Ekuqeqetheni kwezimboni zesimanje, ikhono lokumaka unomphela izingxenye zepulasitiki ngokunemba okuphezulu liye laba yinzuzo enkulu yokuncintisana. Izindlela zokuphrisha zakudala njenge-inkjet noma i-pad printing ziyancipha, zibune, noma ziguge ngokuhamba kwesikhathi, okwenza zingafaneleki ukulandelelwa okuhlala njalo nokubekwa uphawu. I-laser marking masterbatch ixazulula le nkinga ngokufaka amakhemikhali asabela ku-laser ngqo ku-plastic matrix ngesikhathi sokubunjwa komjovo noma i-extrusion. Lokhu kusho ukuthi yonke ingxenye ephuma esikhunjeni isilungile ukumakwa okuhlala njalo okunombala ophakeme ngomzuzu idlula ngaphansi komgqomo we-laser. Izimboni ezisukela kwezobuchwepheshe bezimoto kuya kumadivayisi ezokwelapha kanye ne-aerospace zisebenzisa leli khono ukuze kuhlangatshezwane nezimfuneko ze-UDI, izinombolo zochungechunge, amakhodi e-QR, namalogo ahlala ezindaweni ezinzima. I-Dongguan Dazhan JiYuan New Materials Technology Co., Ltd. iye yaba nochwepheshe ekuthuthukiseni lawa ma-masterbatches asebenzayo iminyaka engaphezu kweshumi, inikeza amafomula asebenza kuwo wonke ama-thermoplastics afana ne-ABS, PC, PA, kanye ne-PBT. Noma ngabe udinga umbala omhlophe-on-omnyama noma omnyama-on-omhlophe, i-laser marking masterbatch efanele iyayisusa imisebenzi yesibili, inciphisa isikhathi somjikelezo, futhi iletha ukufundeka okungaguquguquki ngaphansi kwanoma yiluphi uhlobo lokukhanya. Lo mhlahlandlela uzokuhambisa ngesayensi, izindlela zokukhetha, namasu okuphumelela ukuze uthole imiphumela engcono kakhulu kuphrosesi yakho ye-laser marking.

Isidingo esikhulayo sokunciphisa usayizi nokwenza izinto zibe lula kumakhemikhali ezinto zikagesi zabathengi siye saphusha i-laser marking masterbatch kusuka kokukhethekile okukhethekile kuye ekubeni yimfuneko enkulu. Abakhiqizi abake babekezelela izimpawu ezisekelwe uyinki manje bayashintsha ngoba i-laser marking inikeza izinto ezingasebenzisi, isikhathi esingadingi ukoma, futhi akukho ukukhishwa kwezixazululi. Ngaphezu kwalokho, izinhlaka zokulawula njengomthetho we-FDA's Unique Device Identification (UDI) kanye namazinga okulandelelwa kwe-IATF 16949 embonini yezimoto zidinga izimpawu ezihlala zifundeka ngemva kokubulala amagciwane, ukuchayeka kumakhemikhali, noma ukuguga kwe-UV. I-laser marking masterbatch eyenziwe kahle iqinisekisa ukuthi uphawu alufiphali noma aluhlanekezeli ngisho nasezindaweni ezinzima, zinikeza ama-OEM nabakhiqizi abaqashi ukuthula kwengqondo ukuthi idatha yabo yokulandelelwa izohlala isikhathi sonke sobude bomkhiqizo. I-Dongguan Dazhan JiYuan New Materials Technology Co., Ltd. ihlinzeka ngezixazululo eziqondene nawe ezibhekana nalezi zinkinga ezibucayi, ngokuzinikezelaIsikhungo se-R&D izinsiza zokulungisa izakhiwo kumakhasimende ngamunye we-resin kanye nemvelo yokucubungula.

I-physics eyisisekelo ngemuva kwe-laser marking masterbatch ijikeleza ukumunca i-near-infrared (NIR). Ama-thermoplastics amaningi ngokwemvelo ayabonakala noma ayabonakala kancane ku-wavelength eyi-1064 nm ekhishwa yi-Nd:YAG noma i-fiber lasers ejwayelekile. Ngaphandle komamunci, umgqomo we-laser udlula epolimerini ngaphandle kokudala umaki obonakalayo, uchitha amandla nesikhathi. Izithako ze-Dazhan JiYuan laser marking ziqukethe izakhiwo ezikhethekile ze-NIR-absorbing molecules namapigimenti athwebula la mandla e-photon futhi awaguqule abe ukushisa okwenzeka endaweni ethile. Lokhu kushisa kuqalisa ushintsho olulawulwayo lwe-chemical noma lwe-physical epulasitikini elizungezile, njenge-carbonization (ukumaka okumnyama), ukuvutha (ukumaka okukhanyayo ezindaweni ezimnyama), noma ukushintsha kombala. Okubalulekile ukuthola i-steep thermal gradient ukuze ukusabela kwenzeke kuphela endaweni lapho i-laser igxile khona, kushiya izinto ezizungezile zingathinteki. Ithimba lethu lilungise kahle i-absorption cross-section yalezi zithako ukuze zisebenze kahle ngisho nasezinyathelweni eziphansi, ngokuvamile phakathi kuka-0.5% no-3% ngesisindo kuye ngepolimeri nomphumela ofunwayo.

Inkinga eyodwa ejwayelekile abakhiqizi abayihlangabezana nayo ukumakwa okungahambisani ngenxa yokuhlakazeka okungalungile noma ukungafani kwezindawo zokumunca ukukhanya. I-carbon black ejwayelekile ingakwazi ukumunca ukukhanya kwe-NIR, kodwa yenza umaki omnyama kuphela endaweni emnyama, inganikezi ngokungafani futhi ivame ukulimaza ubuso ngokushisa okweqile. I-chemistry eyengeziwe ye-Dazhan JiYuan ixazulula lokhu ngokusebenzisa ama-metal oxides enziwe ngokucophelela, i-antimony-doped tin oxide ekhethekile, noma ama-organic NIR dyes amunca kakhulu ku-1064 nm ngenkathi ihlala ingabonakali noma cishe ingabonakali ku-polymer eyisisekelo. Lokhu kuvumela lokho umkhakha obiza "ukumakwa okungabonakali" - into eyengeziwe ayishintshi umbala wengxenye yemvelo kuze kube yilapho i-laser iqala ukudubula. Ngaphezu kwalokho, i-Ikhaya ikhasi lichaza ukuthi silawula kanjani ukusatshalaliswa kosayizi wezinhlayiya ukuze kuvinjelwe ukukhanya okuhlakazekayo, okungenjalo kungadala ukubukeka okufiphelele noma okufana nobisi ezintshweni ezicacile. Ngomkhiqizo wethu we-laser marking masterbatch, uthola impahla eyisisekelo ecolekile, engenambala enikeza imaki ezicacile, ezinezinqumo eziphakeme lapho i-laser ihlola khona kuphela.

Njalo masterbatch yokumaka nge-laser evela kwa-Dazhan JiYuan iyinhlanganisela elinganiselayo ngokucophelela yenhlaka ethwalayo, abamunca i-NIR, abakhuthazi bomunye, nezisizi zokucubungula. Inhlaka ethwalayo ikhethwa ukuze ihambisane nenkomba yokugeleza kwe-melt yenhlaka esingumama nokuzinza kwe-thermal, iqinisekisa ukuthi i-masterbatch isakazeka ngokulinganayo ngaphandle kokubola ngesikhathi sokubunjwa komjovo. Abamunca i-NIR yinhliziyo yohlelo, futhi sinikeza imindeni eminingi: izinhlayiya ezincane ze-metal oxide (njenge-molybdenum trioxide noma i-tungsten bronze) ezintweni zobunjiniyela ezishisayo, imibala ye-organic near-infrared ezindaweni ezithintana nokudla, kanye ne-lanthanum hexaboride (LaB₆) ezicelo ezidinga izikhathi zokuphendula ezisheshayo kakhulu. Abakhuthazi bomunye, ngokuvamile i-titanium dioxide noma i-zinc sulfide, kunezwa lapho umaki omhlophe ocwebezelayo udingeka ku-substrate emnyama. Lezi zengezo zisebenza ngokudala amagwebu amancane asakaza ukukhanya okubonakalayo, akhiqize ukubukeka okumhlophe ngokumelene nesizinda esimnyama. Ngaphezu kwalokho, sifaka ama-ejenti okusakaza nama-lubricants ukuvimbela ukuhlanganiswa nokubeka ezindaweni zesikhunta, okwandisa impilo yamathuluzi futhi kunciphisa isikhathi sokungasebenzi.

Ulwazi oluqoqwe ngokusebenzisa iminyaka yesayensi yokwakheka lunikeza i-Dazhan JiYuan inzuzo ehlukile kubahlinzeki be-masterbatch abavamile. IthuMayelana NathiAmagqamisa ekhasini imigqa yethu yokukhiqiza eqinisekiswe yi-ISO 9001 lapho yonke imikhiqizo ihlolwa ukuthola ukusebenza kahle kokumunca ku-1064 nm, ukuzinza kwezinga lokushisa kufika ezingeni lokucubungula irayisi, kanye nokugqama kokumaka okulinganiselwe yi-spectrophotometry. Siphinde sinikeze izinhlobo ezikhethekile ezihlanganisa izivikeli-zomlilo ze-UV ukuvimbela ukuba mthubi komaki ngokuhamba kwesikhathi, kanye nezinhlobo ezihambisana nemithetho yokuthintana nokudla kwezicelo zezokwelapha nezokupakisha. Ngokuhlanganisa lezi zithako ngobuningi obufanele, siletha i-laser marking masterbatch engasebenzi kahle kuphela ngosuku lokuqala kodwa igcina ukusebenza kwayo isigaba ngesigaba, is Shift nges Shift.

Eminye yemibuzo esiyithola njalo kubunjiniyela ukuthi ungayithola kanjani imakhi emhlophe ecacile engxenyeni emnyama uma kuqhathaniswa nemakhi emnyama engxenyeni engokwemvelo noma enemibala elula. Impendulo ilele endleleni yokuphendula eyenziwa yi-laser. Kumakhi amnyama ezintweni eziyisipulasitiki ezilula, i-laser ibanga ukubola: i-NIR absorber ifudumeza i-polymer ngaphezu kwezinga layo lokubola, iguqule ungqimba oluncane lwezinga eliphezulu lube yikhaboni eliyisisekelo. Lokhu kukhiqiza imakhi emnyama, empunga, noma ensundu emnyama ehlala njalo futhi engasuswa kalula. Kumakhi alula ezintweni eziyisipulasitiki ezimnyama, inqubo isebenzisa ukubilisa noma ukukhipha umbala: i-absorber ifudumeza umswakama noma into yokubilisa ngaphakathi kwe-masterbatch, idala amagwebu amancane kakhulu angenamoya asakaza ukukhanya okubonakalayo futhi abonakale njengomhlophe. I-Dazhan JiYuan inikeza imigqa yemikhiqizo ehlukene elungiselelwe inqubo ngayinye, futhi singakwazi ngisho nokulungisa umthunzi ompunga ngokulungisa umthwalo we-absorber kanye nomphromotha wokungafani. Umphumela uhlelo lokumaka oluhlangabezana namazinga aqinile okufundeka kahle okuhlolwa kwamakhodi amabhakhodi (ISO/IEC 15416) nokumakwa kwezingxenye eziqondile (ISO/IEC 15426).

Umehluko awugcini nje ngokubukeka—uthinta ngqo amazinga okufundwa emgqa wokukhiqiza othomathikhi. Uphawu olunezinga eliphansi lokuhluka luphoqa amakhamera okubona ukuthi alungise ngesikhathi eside sokuchayeka namakhodi ayinkimbinkimbi, kanciphise ukukhiqiza. Ngomkhiqizo we-Dazhan JiYuan laser marking masterbatch, uhlale uthola amazinga okuhluka angaphezu kuka-80% (alinganiswa njengo-(R_ongaphawulwanga − R_uphawulwe) / R_ongaphawulwanga), okuvumela amakhamera ajwayelekile ezimboni ukuthi afunde amakhodi ngesivinini somugqa esidlula amamitha angu-60 ngomzuzu. Sikwenza lokhu ngokulawula ngokunembayo ukwakheka kwezinhlayiya zabakhuthazi bokuhluka kanye nezinga lokushisa lokubola kwezinto ezivuthayo. Ngaphezu kwalokho, i-IzixazululoIkhasi linikeza amanothi eningiliziwe esicelo asiza ukukhetha i-masterbatch efanele yokuphuma kombala wakho othize, noma ngabe ubeka i-ABS emnyama yezixhumi zezimoto noma i-polycarbonate emhlophe yezindlu zezokwelapha.

Nakuba i-1064 nm (i-fiber noma i-Nd:YAG) iyisikhathi esivamile sokumakwa kwe-laser yepulasitiki, ezinye izikhathi ezifana ne-532 nm (eluhlaza) noma i-355 nm (i-UV) ngezinye izikhathi zisetshenziselwa ukumakwa okuhle kakhulu kumafilimu amancane noma izinto ezibucayi ekushiseni. I-Dazhan JiYuan's laser marking masterbatch yakhelwe ikakhulukazi i-1064 nm, enikeza ibhalansi engcono kakhulu yokusebenza kahle kokumunca kanye nezindleko ngoba ama-fiber lasers atholakala kabanzi futhi agcina ukusebenza okuphezulu kwe-wall-plug. Kodwa-ke, sinikeza nezigaba ezikhethekile ezilungiswe nge-532 nm noma ama-CO₂ lasers (10.6 µm) kumakhasimende anezinto ezikhona kulezo zikhathi. Ukucushwa kwe-pulse kubaluleke kakhulu njengoba kunjalo ne-wavelength: ama-nanosecond pulsed lasers ajwayelekile ekumakeni i-masterbatch ngoba isikhathi se-pulse sifushane ngokwanele ukudala amandla aphezulu ngaphandle kokuncibilikisa ipulasitiki eyinhloko. Izithako zethu zakhiwe ukuze ziphendule kahle ezikhathini ze-pulse phakathi kwe-5 ns kanye ne-200 ns, nge-peak absorption ehambisana namandla ajwayelekile we-20–50 kW/cm² ahlinzekwa yi-pulsed fiber laser.

Lapho ushintsha phakathi kwamapholima ahlukene, ungadinga ukulungisa kokubili ukwakheka kwe-masterbatch kanye namapharamitha e-laser. Ngokwesibonelo, i-PBT ne-PET zithatha amandla e-laser amaningi kune-polypropylene ngenxa yamaqembu azo e-carbonyl, ngakho-ke ukulayisha okuncane komthamo kanye namandla e-laser aphansi kuyadingeka ukuze kugwenywe ukushiswa ngokweqile. I-Dazhan JiYuan ihlinzeka ngamathebula aqondisa ukwakheka ku-Imikhiqizo ikhasi, likuvumela ukuthi ukhethe izinga elifanele le-masterbatch ngokusekelwe emndenini wakho we-resin nombala wokumaka oyifunayo. Siphinde senze izivivinyo zokucubungula nge-laser elabhorethri yethu, lapho sifanisela imodeli yakho ye-laser, ukucushwa kwelensi, nesivinini sokukhiqiza ukuze sincome amapharamitha okuqala afanele. Le ndlela yokusebenza ngokuqondile inciphisa isikhathi sokuzama nokuhluleka esitezi sakho sasefektri, songa kokubili ukuchitha izinto kanye nesikhathi sokuma komshini.

Ukukhanya (amandla ngendawo, avame ukuboniswa ku-W/cm²) kanye ne-fluence (amandla ngendawo, J/cm²) yizona zimiso ezimbili ezibaluleke kakhulu ukuze kufezekiswe amamaki angaguquki. Ukukhanya okuphansi kakhulu futhi i-NIR absorber ayifinyeleli umkhawulo wayo wokuvula, kushiya umaki ongabonakali. Ukukhanya okuphezulu kakhulu futhi i-absorber iyashisa kakhulu, ibangele ukubila, ukushiswa, noma ngisho nokudabuka, ikakhulukazi ezingxenyeni ezinezindonga ezincane. Ithimba lobuchwepheshe le-Dazhan JiYuan lincoma ukuqala ngokukhanya okungu-5–15 MW/cm² kwi-thermoplastics eziningi eziqukethe i-masterbatch yethu ku-1–2% yokulayisha. Usayizi wechashaza ubaluleke ngokufanayo: ichashaza elincane (0.05–0.2 mm) ligxilisa amandla ombhalo omuhle namakhodi anencazelo ephezulu, kanti ichashaza elikhulu (0.3–0.6 mm) lingcono ekugcwaliseni izindawo ezifana namalogo noma izithunzi zangemuva. Siyeluleka amakhasimende ukuthi asebenzise ama-telecentric F-theta lenses ukuze agcine usayizi wechashaza ongaguquki kulo lonke insimu yokumaka, okususa ukuhlanekezela komphetho okungadala ukwehluleka ukufunda kumakhodi e-Data Matrix.

I-Fluence kufanele ilungiswe ngokulungisa amandla e-laser, isivinini sokuskena, kanye ne-pulse repetition frequency (PRF). Umthetho omuhle uwukugcina i-fluence phakathi kuka-1 no-6 J/cm² ukuze kumakwe okumnyama naphakathi kuka-3 no-8 J/cm² ukuze kumakwe okubilayo (okumhlophe). Uma umaki ubonakala ubuthakathaka kakhulu, khulisa amandla noma wehlise isivinini sokuskena; uma ubonakala umnyama kakhulu noma ubushelelezi, yehlisa amandla noma khulisa isivinini sokuskena. Yethu Ibhulogiinokwethula uchungechunge lwezifundo ezibonisa izithombe zangaphambi nangemva kokulungiswa kwamapharamitha ezinhlobonhlobo zezimo, njengezindawo ezijikileyo kumajekese ezokwelapha noma i-flash encane kuma-connectors kagesi. Siphinde sigcizelele ukubaluleka kwebanga lokugxila elingaguquki: ngisho nokuhlehlisa okungu-1 mm kunganciphisa i-irradiance ngo-30% noma ngaphezulu, okuholela emakhazeni angaguquki kuwo wonke umkhiqizo. Ngokuhlanganisa i-laser marking masterbatch yethu nokulawula okuzinzile kwamapharamitha, uthola amamaki aphindaphindeka kalula, anombala ophakeme adlula izivivinyo zekhwalithi eziqinile kakhulu.

Ukugxila kokulayisha kwe-masterbatch yokumaka nge-laser kuthinta kakhulu ikhwalithi yokumaka kanye nenani eliphelele ngezinga ngalinye. Ukusebenzisa okungeziwe okuncane kubangela umaki ongabonakali noma ongagcwalisiwe ngoba abekho abamunca i-NIR abanele ukubangela ukusabela. Ukusebenzisa okungeziwe okuningi kudlala izinto futhi kungadala imiphumela engemihle njengezici zemishini ezincishisiwe, ukwanda komhwamuko ezingxenyeni ezicacile, noma ukukhishwa okweqile ngesikhathi sokubumba. I-Dazhan JiYuan ithuthukise inqubo elula yokulungisa ukulayisha: ukuze kube nomaki omnyama, sivame ukuncoma u-1-2% ngesisindo se-masterbatch kuya ku-resin; ukuze kube nomaki omhlophe, u-2-3% ngoba ukusabela kokubumba kudinga isilinganiso esiphakeme sama-blowing agents kanye nabakhuthazi bokungafani. Ngoba i-masterbatch yethu igxilile kakhulu, ufinyelela la malayisho ngendleko encane yezinto ezingeziwe, uvame ukwengeza ngaphansi kwe-USD 0.01 ngezinga elithile lengxenye engu-50 g. Lokhu kwenza i-masterbatch yokumaka nge-laser ibe yinye yezindlela ezingabizi kakhulu zokumaka ezitholakalayo lapho ubheka izinto ezingadliwa kanye nezinqubo zesibili ezingekho.

Ngaphandle kokonga okuqondileyo kwezinto, amafomula ethu athuthukisa isantya somjikelo ngeendlela ezimbini. Okokuqala, i-absorption kinetics ekhawulezayo ivumela i-laser ukuba isebenze kwiisantya eziphezulu zokuskena—ukuya kuthi ga kwi-12,000 mm/s kunye ne-fiber lasers ezisemgangathweni—ngaphandle kokudela umbala. Okwesibini, kuba i-masterbatch yenzelwe ukwenza uphawu olucocekileyo kwisigaba esinye, uyayiphelisa imfuneko yeemijikelo ezininzi ze-laser, ezinokuphinda kabini okanye ziphindwe kathathu ixesha lomjikelo. Abavelisi abatshintshela kwi-Dazhan JiYuan laser marking masterbatch ngokuqhelekileyo babika ukuncipha kwe-30–50% kwixesha elipheleleyo lomjikelo wokumakisha xa kuthelekiswa neepakethi ezongezelelweyo eziqhelekileyo. Idibene nokupheliswa kwe-inki, i-solvents, iilebula, kunye nexesha lokuseta i-pad printing, ukuphuculwa kweendleko zokuba nazo ngokubanzi kubalulekile. YethuXhumana Nathi ikhasi linikeza ukufinyelela ngqo onjiniyela bezicelo abangakwazi ukubala imali oyongayo ngokusekelwe kunqubo yakho yokumaka yamanje kanye nomthamo wokukhiqiza.

Izinsiza eziningi zobunjiniyela ezisetshenziswa ezintweni zikagesimende nezimoto kumele zibe nezinto ezivimbela ukushisa (FRs) ukuze zihlangane nezilinganiso ze-UL 94 V-0 noma V-2. Inkinga ejwayelekile ukuthi izinto ezithile ezivimbela ukushisa, ikakhulukazi izinhlobo ezine-bromine noma ezisekelwe ku-phosphorus, zingaphazamisa ukusabela kokumakwa nge-laser ngokumunca amandla e-laser ngokwazo noma ngokubola ezingeni lokushisa elingaphansi komkhawulo wokushisa ube yikhala. I-Dazhan JiYuan ixazulule lokhu ngokuthuthukisa uchungechunge oluthile lwe-masterbatch yokumakwa nge-laser ehambisana namakhemistri nezinhlelo ezivame kakhulu ze-FR, okuhlanganisa izithako ezine-halogen, i-organophosphorus, nezisekelwe emaminerali. Ifomula yethu ilungisa amakhemistri omthumeli ukuze isebenze ezingeni lokushisa eliphezulu, iqinisekisa ukuthi ukusabela okubangelwa yi-laser kudlula ukumunca okungafunwa kusuka kusithako se-FR. Siphinde silungise i-resin ethwele ukuze sigcine amandla okushayeka kanye nokwelulwa lapho kuphuka, okungahle konakaliswe lapho kusetshenziswa ama-masterbatch ajwayelekile ezimweni ezine-FR.

Ukuhlolwa kwensimu okwenziwe nabakhiqizi abakhulu bezithintayo zomlilo kubonisa ukuthi izingxenye ezinama-FR additives kanye ne-Dazhan JiYuan laser marking masterbatch zigcina isilinganiso sazo se-UL 94 futhi azibonisi ukwehla kwisilinganiso sokuphelelwa umoya (LOI). Siphinde siqinisekise ukuthi i-masterbatch ayisebenzi njengendlela yokuthuthela komlilo ukuze ukhanye ebusweni, okungadala iziphepho zobuhle kanye nezinkinga zezempilo ezingenzeka. Kumakhasimende afuna izinga eliphezulu kakhulu lokuhambisana, i-Izixazululoikhasi liqukethe isihlobo sokuhambisana esihlobanisa izigaba zethu ze-masterbatch nemindeni ethile ye-FR nezinhlobo zemichiza. Lokhu kuhlelwa kusenesikhathi konga amasonto okuzama nokuhluleka futhi kuqinisekisa ukuthi umkhiqizo wakho wokugcina uhlangabezana nezidingo zokusebenza kokumaka kanye nezokuphepha ngesikhathi esisodwa.

Ezimeni ezilawulwayo njengemishini yezokwelapha, ukupakisha ukudla, nokuphepha kwezimoto, noma yisiphi isengezo esingeniswa ku-resin yepulasitiki kumele sihlangane nokuqinisekiswa okunzulu kokuhambisana. I-Dazhan JiYuan laser marking masterbatch yenziwa ngaphansi kwezinhlelo zokuphatha ikhwalithi ye-ISO 9001:2015, futhi izithako zethu zamakhemikhali zikhethwa kubahlinzeki abanikeza izimemezelo ezigcwele zomthetho. Ezicelo zezokwelapha, sinikeza izigaba ezihambisana ne-FDA 21 CFR 175.105 (izincibilikisi) kanye ne-21 CFR 177.1520 (ama-olefin polymers), okwenza zifanelekele amadivaysi ezokwelapha we-Class I ne-Class II adinga ukumakwa kwe-UDI. Lezi masterbatches zadlula ukuhlolwa kwe-cytotoxicity (ISO 10993-5) futhi azibonisi ukuthi kukhona okungaphuma ngaphansi kwezimo zokubulala amagciwane ezilinganisiwe. Amakhasimende ezimoto, ama-masterbatches ethu ahlangabezana nemikhawulo ye-volatile organic compound (VOC) kanye ne-fogging echazwe izindinganiso ezinkulu ze-OEM njenge-BMW GS 97034-3 kanye ne-VW PV 3900.

Ukuqashelwa yi-UL kuyisidingo esibalulekile esinye sezinto ezisetshenziswa ezindlini zikagesi, izixhumi, nezishintshi. I-Dazhan JiYuan isebenza ngqo ne-UL ukuze ithole izinhlu ze-Yellow Card zemikhiqizo yethu lapho isetshenziswa ezinsizeni ezifanelekayo, iqinisekisa ukuthi isengezo asinciphisi i-RTI (Relative Thermal Index) yempahla noma isigaba sayo sokuvutha. Sihlinzeka ngamaphakheji aphelele emibhalo, okuhlanganisa amashidi edatha yokuphepha kwezinto (MSDS), amashidi edatha yezobuchwepheshe (TDS), kanye nezincwadi zokumemezela ukuhambisana, ukuze kube lula inqubo yakho yokuqinisekisa. YethuMayelana Nathiikhasi lichaza ukuzibophezela kwethu ekuqiniseni imigomo, futhi ithimba lethu lekhwalithi lihlola njalo uchungechunge lwethu lokuhlinzekwa ukuze liqinisekise ukuthi zonke izindawo ze-masterbatch yokumaka nge-laser zihlangabezana nezicaciso ezidingwa izinhlangano ezilawula imboni yakho.

Ngisho ne-masterbatch enhle kakhulu yokumaka nge-laser izokwehluleka uma ingahlanganisiwe kahle ku-plastic matrix. Izinhlayiya ze-absorber ezihlangene zakha izindawo ezishisayo ezikhiqiza amamaki angalingani, kanti izindawo ezicebile nge-resin azikhiqizi nhlobo imaki. Umthetho wegolide ukusebenzisa i-masterbatch esihlangene kakade ku-resin ethwalayo ehambisanayo ene-melt flow index (MFI) eseduze ne-resin yakho eyisisekelo. Amaphilisi e-masterbatch e-Dazhan JiYuan akhiqizwa kusetshenziswa i-twin-screw extrusion enezindawo zokuxuba eziqinile ezichitha izinhlayiya ezihlangene zibe usayizi wezinhlayiya d99 ongaphansi kuka-5 µm. Kumshini wakho wokubumba nge-injection, sincoma ukusebenzisa i-screw ejwayelekile enesilinganiso esincane se-L/D esingu-20:1 kanye ne-mixing screw tip (njengohlobo lwe-Dulmage noma i-pineapple) ukuze uhlanganise ngisho nangokwengeziwe i-melt. Uma usebenzisa i-gravimetric blender, setha ukudla kwe-masterbatch maphakathi ne-screw ukuze uvumele ibanga elanele lokuncibilika ngaphambi kokubumba.

Ukomisa kungenye into ephinde inganakiwe: amabanga athile e-laser marking masterbatch aqukethe abomisa amanzi abuthakathaka noma ama-blowing agents, ngakho-ke sincoma ukugcoba i-masterbatch ku-80–100 °C imizuzu engu-2–4 ngaphambi kokucubungula, ikakhulukazi ezinhlelweni ze-polyamide noma i-polycarbonate. Ukuhambisana kwe-regrind nakho kubalulekile—sihlolile i-masterbatch yethu nge-regrind content engu-30% futhi sabona ukwehla okuncane ekugqamiseni komaki, inqobo nje uma i-regrind ingangcolisiwe ngezinto ezingahambisani. Sishicilela imihlahlandlela enemininingwane yokucubungula ku-Imikhiqizo ikhasi, okubandakanya amaprofayela okushisa komgqomo anconyiwe, izilungiselelo zengcindezi yangemuva, nezindawo zokujikeleza kwe-screw ezintshweni ezivamile kakhulu. Ukulandela le miqondiso kuqinisekisa ukuthi i-laser marking masterbatch yakho yenza njengoba ihlelwe, ingxenye ngengxenye, ngesilinganiso esincane sokuchitha.

Abahlinzeki be-masterbatch yokumaka nge-laser abafani bonke—abaningi banikeza imikhiqizo eyodwa elingana konke esebenza kahle kuma-polyolefins ajwayelekile kodwa ihluleka kuma-plastics obunjiniyela noma izicelo ezikhethekile. I-Dazhan JiYuan izihlukanisa ngokunikeza izinsizakalo zokwakheka ngokwezifiso ezisekelwa yithimba le-R&D elizinikele elineminyaka eminingi yesipiliyoni ezintweni ezisebenzayo. Sivame ukukhethwa lapho ikhasimende lidinga umbala othile wokumaka (omhlophe okumsulwa, omnyama okukhanyayo, noma isikali esithile esimpunga), lapho inhlaka eyisisekelo iqukethe izivimbeli zomlilo noma ezinye izithako ezibangela ukuphazamiseka, noma lapho ukuthobela imithetho kufuna ukulandelelwa okubhalisiwe kwakho konke okwakhiwa amakhemikhali. Siphinde sibe namandla ezindaweni zokukhiqiza ezisheshayo lapho ukuncishiswa kwesikhathi sokujikeleza kuguqulela ngqo ekongeni izindleko. Uma inqubo yakho yokumaka yamanje iyisithiyo, noma uma wethula umkhiqizo omusha odinga ukumakwa unomphela ngaphandle kwezinyathelo zesibili, i-Dazhan JiYuan laser marking masterbatch iyisixazululo esiklanyelwe ukuhlangabezana nezidingo zakho eziqondile.

Sikumema ukuthi uhlole i-masterbatch yethu esikhungweni sakho ngokusebenzisa uhlelo lwethu lwesampula. Xhumana NathiIkhasi liqukethe ifomu lapho ungacela khona kufika ku-5 kg wezinto zokuhlolwa okukhiqizayo, kanye nedatha yezobuchwepheshe echaza amaparamitha elaser anconyiwe we-resin yakho. Onjiniyela bethu bezicelo bayatholakala ukuze basize ngohlelo olukude noma olusekhona ukukusiza uthuthukise inqubo kusukela ekuqaleni kuze kube sekugcineni. Ukukhetha i-Dazhan JiYuan kusho ukukhetha umngane otshala imali empumelelweni yakho, hhayi nje umphakeli othumela iphalethi ejwayelekile. Ngaphezu kweminyaka eyishumi yokuqamba izinto ezithuthukisa i-laser marking, sinomlando, izitifiketi, kanye nobuchwepheshe obuqinile bokukhuphula izinga lezingxenye zakho zepulasitiki zibe sezingeni elisha lekhwalithi nokulandelelwa.

I-masterbatch yokumaka nge-laser ubuchwepheshe obuguqulayo obuvumela ukumakwa okuhlala njalo, okunamandla aphezulu ngqo ezingxenyeni zepulasitiki ngaphandle kwanoma yiziphi izinto ezingasetshenziswa. I-Dongguan Dazhan JiYuan New Materials Technology Co., Ltd. inikeza uhla olubanzi lwezibonelo ze-masterbatch ezixazulula izinselele zobuchwepheshe eziyinhloko: ukumunca i-NIR, ukuthuthukisa okungafani, ukuhambisana nezinto ezicisha umlilo, kanye nokuhambisana namazinga e-FDA, ISO, ne-UL. Ngokukhetha izinga le-masterbatch elilungile, umthamo wokulayisha (uvame ukuba ngu-0.5–3% ngesisindo), namapharamitha e-laser (ubude bamaza obungu-1064 nm, i-irradiance engu-5–15 MW/cm², kanye ne-fluence engu-1–6 J/cm² yokumakwa okumnyama), abakhiqizi bangakwazi ukuthola amamaki acacile, aqinile ngesivinini somugqa esithuthukisa ukusebenza kahle kwemishini. I-masterbatch yethu esakazwe ngaphambili iqinisekisa ukusakazeka okufanayo, futhi isikhungo sethu se-R&D sihlinzeka ngokusekelwa kokwakheka okwenziwe ngokwezifiso kwezicelo ezidingekayo embonini yezimoto, ezokwelapha, ezikagesi, kanye nezomkhathi.

Sikukhuthaza ukuthi usebenzise izinsiza zangaphakathi esizihlanganyele kulo lonke lesi sihloko—iIkhaya ikhasi ukuze uthole ukubuka konke ngenkampani, i-Isikhungo se-R&Dikhasi ngobuchwepheshe obujulile, i-Imikhiqizoikhasi lokukhetha isigaba, i-Izixazululo ikhasi lezicelo zemboni, kanye ne-Ibhulogiukuze uthole izifundo ezisebenzayo. Okubalulekile ukuthi ukumakwa kwe-plastic nge-laser okuphumelelayo kuyisistimu ephelele: i-chemistry ye-masterbatch, izilungiselelo ze-laser, kanye nenqubo yokubumba kufanele kusebenze ngokuvumelana. Nge-Dazhan JiYuan njengomlingani wakho we-formulation, uthola ukufinyelela kulo lonke ulwazi lwesayensi yezinto, umlando oqinisekisiwe wokuthobela imithetho, nokuzibophezela ekukusizeni ukufeza imikhomba ephelele njalo. Thinta ithimba lethu namuhla ukuze uqale ukuhlolwa kwakho futhi uzizwe umehluko ongawenza i-masterbatch ye-laser marking eyakhelwe injongo kwimikhiqizo yakho.
