Kuyini ukuphulukiswa kwe-UV kwama-adhesives?

Inqubo yokuphulukisa i-UV yobuchwepheshe bokunamathisela iqukethe izinyathelo ezine eziyisisekelo:

Isicelo Sokunamathisela:

I-glue ezwela ukukhanya noma i-UV adhesive ibekwe ebusweni bokubopha, okungaba ingilazi, ipulasitiki, insimbi, noma izinhlanganisela.

Ukuqondanisa:

Izakhi zibekwa endaweni ngendlela eqondile kakhulu ukuze kufinyelelwe ngisho nokuxhumana phakathi kwezingqimba zokunamathisela.

Ukuchayeka kokukhanya kwe-UV:

Uhlelo lokuphulukisa lwe-UV LED noma uhlelo lwesibani sokuphulukisa i-UV luwumthombo wama-wavelengths athile (imvamisa i-365nm noma i-395nm) ukwenza kusebenze ama-photoinitiators.

Ukwelapha nokuqina:

I-photopolymerized adhesive ithatha imizuzwana embalwa ukwelapha, futhi ingaphulukisa ngokuphelele ngobuqotho obuvelele besibopho esivelele.

Yonke inqubo izosusa ukusetshenziswa kokuphulukisa ukushisa noma isikhathi eside sokumiswa futhi inikeze ubuchwepheshe bokunamathisela obusheshayo, obuthuthukisa ukusebenza kahle kokukhiqiza futhi bunciphise ukusetshenziswa kwamandla.

UV-Curable Adhesives are of various

types

I-UV-Epoxy Resins

Izinamathiselo ezenziwe nge-epoxy zilungele kakhulu ukubopha kwesakhiwo lapho kudingeka khona amandla aphezulu okubopha lapho usebenza ngokukhanya kwe-UV. Esinye sezicelo ezijwayelekile ekwenzeni i-elekthronikhi nasekukhiqizeni izimoto.

I-Acrylic Acids, Ukunamathela Okuphulukisayo kwe-UV

Ama-Acrylics nawo ayaziwa ukuthi anejubane eliphakeme le-ejenti yokubopha kanye nokuphulukiswa kokushisa okuphansi kwe-UV, okusetshenziselwa ukubopha i-lens optical kanye nokukhiqizwa kwezingxenye zepulasitiki.

Izindlela zokusebenzisa i-UV-Curable Pressure-Sensitive Adhesives (PSA)

Lezi zinamathelayo zingasetshenziswa emaphaketheni nasezinhlosweni zokulebula, futhi zinikeze izixazululo ezisheshayo ekuhlanganisweni kwe-UV ezingenakukhishwa futhi zingagugi. 

I-Polyurethane ne-UV-Curable silicone Adhesives

Ukusetshenziswa kwazo kuyaguquguquka, kunembile ekuhlanganisweni kwe-UV, futhi kuyahambisana ne-biocompatible; lokhu kubenza babe balulekile ezinqubweni zokubopha i-aerospace namadivayisi wezokwelapha.

Izinzuzo ze-UV-Curable Adhesives

 Ukwelashwa okusheshayo nokuphumelelayo

Inqubo yokuphulukisa izinamathiselo ze-UV ithatha imizuzwana embalwa ukuqedela i-polymerization, futhi uma kuqhathaniswa, nezinqubo zokukhiqiza ezijwayelekile, ezisebenzisa ukushisa noma ama-solvents, inqubo ithatha isikhathi esiningi.

 I-Solvency-Free futhi inobungani bemvelo

Iningi lezinhlelo zokunamathela zokuphulukisa i-UV azincibilikisiwe, futhi zikhiqiza ukukhishwa okuncane kakhulu kwe-VOC; ngakho-ke, zingama-adhesives we-UV anobungani be-eco-friendly angasetshenziswa ekukhiqizeni ngokuzinzile

.

Ukunemba nokusebenza okuphezulu

Isibani sokuphulukisa i-UV adhesive sinikeza ubude obufanayo bokuphulukisa kanye nokubopha okunembile kwe-UV ngamandla aphezulu okubopha nokucaca okuhle kakhulu kwe-optical.

 Ukonga amandla nokushisa okuphansi

Inqubo yokuphulukisa izibani ze-UV ze-LED idinga amandla amancane uma kuqhathaniswa nezibani ze-mercury, eziqhubeka nokugcina izinhlelo zokuphulukisa ezisebenza kahle ezithuthukisa isikhathi eside semishini nezindleko zokusebenza.

 Ukuthuthukiswa kokuhambisana kwezinto ezibonakalayo

Izinamathiselo zokubopha i-UV zingabopha ama-substrates ahlukahlukene, njengengilazi, izinsimbi, i-ceramics, namapulasitiki, futhi agcine amandla okunamathisela ekukhanyeni kwe-UV.

Ukuqonda kwezobuchwepheshe: Ukucaciswa kwe-UV Curing System

Uhlelo lokunamathisela lwe-UV LED lwanamuhla luhlanganisa:

Ububanzi be-Wavelength: 365nm-405nm (elungiselelwe amakhemikhali amaningi wokunamathisela)

Ukukhanya: 1-30 W / cm2 (i-viscosity yokunamathela kanye nohlobo lwe-substrate).

Ukulawulwa kokuqina kwe-UV: Ukuncika kwamandla okuguquguqukayo kokusebenza kahle kokuphulukisa kwe-UV.

Uhlelo lokupholisa: Izinhlelo zoketshezi noma zomoya ezipholile (izinga lokushisa elizinzile).

Isikhathi Sokwelapha: 1-20 imizuzwana ukwelashwa okugcwele.

Uhlobo lwesibani. I-LED, i-mercury noma i-hybrid.

Ku-UV NDT, imishini yethu yokuphulukisa ye-UV yobuchwepheshe obuphezulu yakhelwe ngokunemba, ukuthembeka, nokusimama, ngaleyo ndlela ikhiqize ukusebenza kwekhwalithi ephezulu kakhulu kuzo zonke izinqubo zokubopha.

UV Curing in the Contemporary

Industry

Ukukhiqizwa kwe-elekthronikhi

Ku-elekthronikhi, ukuphulukiswa kwe-UV ku-PCB adhesive bonding kunikeza ukuzinza okushisayo, ukumelana namakhemikhali, nokuphulukiswa okusheshayo ezintweni ezifana nama-microchips, izinzwa, kanye ne-fiber optics.

Imboni Yezimoto

Ukubopha kwe-UV ekukhiqizeni izimoto kuthuthukisa ukuqina kwamalambu, izikrini ze-infotainment zemoto, nokubopha kwesakhiwo esilula.

Amadivaysi wezokwelapha

Izinamathiselo ezisetshenziswa kumadivayisi wezokwelapha ziphulukisiwe kusetshenziswa i-UV, eqinisekise ukuthi amalunga ayinyumba, ahambisana ne-biocompatible, futhi aqinile adingekayo kuma-catheter, amasirinji, nemishini yokuxilonga.

Ukubopha kwe-Optical

Ukubopha kwe-optical kuphulukiswa kusetshenziswa i-UV ukuhlinzeka ngokungabi bikho kwamabhamuza ahlinzeka ngokusobala, okufanelekile izikrini zokuthinta, amalensi, namaphaneli okubonisa.

I-Aerospace nezokuvikela

Ukubopha kwesakhiwo kungenzeka ngezinto ezihlanganisiwe ze-UV, ezihlinzeka ngobuningi be-crosslinking kanye ne-polymerization kinetics ezivumelanisa nezimo ezimbi kakhulu.

Photopolymerization Chemistry and Mechanism

I-UV yokuphulukisa i-chemistry ifaka ama-acrylate monomers, ama-oligomers, nama-photoinitiators, asabela ekukhanyeni kwe-UV. Ukusabela kungenziwa ngezindlela ezimbili:

Ukwelashwa kwamahhala kwe-radical:

Isebenza kumasistimu we-acrylate, futhi inephulukisa okusheshayo nokubopha okuhle.

Ukuphulukiswa kwe-Cationic:

Imvamisa itholakala kuma-resin e-epoxy, ukumelana okuqinile kwamakhemikhali nokushisa.

Ukusebenza nokuqina kokubopha okuphulukisiwe kungumphumela wokulinganisela phakathi kokuminyana kokuxhuma nokunamathela ngaphansi kwe-UV.

Control of UV Curing Intensity and Wavelength

Kubalulekile ukukhetha ukuqina okufanelekile kokuphulukisa kwe-UV nobude be-wavelength ukuze uthuthukise ukusebenza kwama-adhesives:

Okunamathisela kwe-Epoxy: Ukuphulukiswa okujulile kokunamathisela kwe-epoxy.

I-385nm: Ukwelashwa kwe-acrylics ye-universal.

I-395nm-405nm: Izinhlelo ze-LED zokuphulukisa okusheshayo ebusweni.

Ukulinganiswa kokukhanya kwe-UV kwethuluzi lokuphulukisa kungasetshenziswa ukuqinisekisa ukungaguquguquki nokuphindaphinda kuwo wonke amaqoqo okukhiqiza, ngakho-ke, ukuqinisekiswa kwekhwalithi kulula futhi kunembile kakhulu.

Energy Saving and Eco-Friendliness

Ngokuguqulwa kwezimboni zibe yizinqubo eziluhlaza, izinhlelo zokuphulukisa ze-UV ze-LED ziye zaba yisikhetho, ngoba zidla amandla amancane, zinesikhathi eside sokuphila futhi ngaphandle kwe-mercury-free. Izinhlelo zokuphulukisa ze-LED vs mercury UV zikhonjisiwe ukuthi zinokonga amandla afinyelela ku-60%, uma kuqhathaniswa nezinhlelo zendabuko, ezithethelela ukusimama komhlaba wonke.

Ukuhlaziywa kwemakethe kanye nezibikezelo zesikhathi esizayo

Ngokokuqonda kwakamuva kwemakethe, umbiko wemakethe yokunamathisela we-UV wokuphulukisa we-2025 ukhombisa ukuthi imakethe kulindeleke ukuthi ikhule kakhulu endabeni yezimakethe zezimoto, i-elekthronikhi neyokupakisha. Isizukulwane esilandelayo sokunamathela ukuphulukisa kanye nezixazululo zokuphulukisa i-UV eziqondene namakhasimende zifunwa kakhulu ngenxa ye-automation kanye nezidingo zokukhiqiza ezinobungani bemvelo. Izinkampani ezinjenge-UV NDT zihola ushintsho olunjalo futhi zihlinzeka abakhiqizi bezimboni zokunamathela kwe-UV ngezinhlelo ezintsha zokuphulukisa ze-UV nezixazululo.

Isiphetho

Ukuphulukiswa kwe-UV kwama-adhesives kungenye yezinto ezibalulekile embonini yokubopha. Ukuphulukiswa kwe-UV sekuphenduke indawo esheshayo yezinhlelo ezishisayo nezisuselwa ku-solvent ngenxa yejubane layo elingakaze libonwe ngaphambili, ukunemba, nokusimama. Ikusasa lokubopha lisekuphulukiseni ukukhanya kwe-ultraviolet, kungaba ekukhiqizeni i-elekthronikhi, imishini yezokwelapha, noma ukukhiqizwa kwezimoto. Izinhlelo zokuphulukisa ze-UV ezisezingeni eliphakeme, izibani zokuphulukisa zokunamathisela, nezixazululo ezenziwe ngokwezifiso ekuhlanganiseni. Ukuze ufunde ngokuphulukiswa okuhle kakhulu kwe-UV, vakashela i-UVET, ukukhetha kwethu okuthandayo endaweni yokuphulukiswa kwe-UV yezimboni.
