Iyini iglue ye-UV?
Igama elithi "glue ye-UV" ngokuvamile libhekisela kuglue engenamthunzi, eyaziwa nangokuthi inhlaka ezwela ukukhanya noma elaphekayo ye-ultraviolet. Iglue ye-UV idinga ukuqiniswa ngokuvezwa ekukhanyeni kwe-ultraviolet futhi ingasetshenziswa ekuhlanganiseni, ekupendeni, ekumbozeni, nakwezinye izinhlelo zokusebenza. Isifinyezo esithi "UV" simelela imisebe ye-Ultraviolet, okuyimisebe ye-electromagnetic engabonakali enamaza obubanzi asukela ku-110 kuya ku-400nm. Isimiso ngemuva kokuqiniswa kwe-UV engenamthunzi sihilela ukumuncwa kokukhanya kwe-ultraviolet yi-photoinitiators noma i-photosensitizers entweni, okuholela ekwakhiweni kwama-free radicals noma ama-cation asebenzayo aqala i-polymerization kanye nokusabela kokuxhumanisa ngemizuzwana.
Inqubo yokunamathela iglue engenamthunzi: iglue engenamthunzi ibizwa nangokuthi iglue ye-ultraviolet, kumele ibe ngemisebe ye-ultraviolet iye kuglue ngaphansi kwesisekelo sokwelapha, okungukuthi, i-photosensitizer kuglue engenamthunzi futhi ukuxhumana nokukhanya kwe-ultraviolet kuzohlangana ne-monomer, ngokwethiyori ngaphandle kokukhanyiswa komthombo wokukhanya kwe-ultraviolet iglue engenamthunzi cishe ngeke yelapheke. Uma ijubane lokwelapha le-UV liqina, isikhathi sokwelapha esijwayelekile sisuka kumasekhondi ayi-10-60. Iglue engenamthunzi kumele ikhanyiswe ngokukhanya ukuze ilapheke, ngakho-ke iglue engenamthunzi esetshenziselwa ukubopha ngokuvamile ingaxhunyaniswa nezinto ezimbili ezisobala noma eyodwa yazo kumele ibonakale, ukuze ukukhanya kwe-ultraviolet kudlule futhi kukhanye kuglue.
Izici zeglue ye-UV
1. Ukuvikelwa/ukuphepha kwemvelo
Akukho ukushaqeka kwe-VOC, akukho ukungcola emoyeni ozungezile; izithako ezinamathelayo azikhawulelwe kakhulu noma azivunyelwe emithethweni yezemvelo; akukho ncibilikisi, akukho ukusha okuncane
2. Kulula ukuyisebenzisa futhi ithuthukisa ukusebenza kahle kokukhiqiza
Ijubane lokusila liyashesha futhi lingaqedwa ngemizuzwana embalwa kuya kweshumi lemizuzwana, okuzuzisa imigqa yokukhiqiza ezenzakalelayo futhi kuthuthukisa umkhiqizo wabasebenzi. Ngemva kokusila, singahlolwa futhi sithuthwe, konge isikhala. Ukusila ekamelweni lokushisa konga amandla, njengokukhiqizwa kwesinamathelisi esimelana nokucindezela esingu-1g. Amandla adingekayo yi-1% kuphela yesinamathelisi esisekelwe emanzini esihambisanayo kanye ne-4% yesinamathelisi esisekelwe ku-solvent. Singasetshenziswa ezintweni ezingafaneleki ukusila okushisa okuphezulu. Amandla asetshenziswa ukusila kwe-ultraviolet angonga u-90% uma kuqhathaniswa ne-resin yokusila yokushisa. Imishini yokusila ilula futhi idinga kuphela izibani noma amabhande okuhambisa. Ukonga isikhala; uhlelo lwengxenye eyodwa, akukho ukuxuba okudingekayo, kulula ukuyisebenzisa.
3. Ukuhambisana
Izinto ezizwela izinga lokushisa, izinyibilikisi kanye nomswakama zingasetshenziswa.
Lawula ukuqiniswa, isikhathi sokulinda singalungiswa, izinga lokuqiniswa lingalungiswa. Iglue ingasetshenziswa ngokuphindaphindiwe ukuze kuqiniswe izikhathi eziningi. Isibani se-UV singafakwa kalula emgqeni wokukhiqiza okhona ngaphandle kwezinguquko ezinkulu.
4. Uhlu olubanzi kakhulu lwesicelo kanye nomphumela omuhle wokubopha
Iglue ye-UV inezindlela eziningi zokusebenza futhi inemiphumela emihle kakhulu yokubopha phakathi kwepulasitiki nezinto ezahlukahlukene. Inamandla aphezulu okubopha futhi ingaphula umzimba wepulasitiki ngaphandle kokukhipha i-gum ngokusebenzisa izivivinyo zokubhujiswa. Iglue ye-UV ingabekwa ngemizuzwana embalwa, futhi ifinyelele amandla aphezulu ngomzuzu owodwa;
Ibonakala kahle ngokuphelele ngemva kokuphola, futhi umkhiqizo ngeke ube phuzi noma ube mhlophe isikhathi eside. Uma kuqhathaniswa nokubopha okunamathelayo okusheshayo kwendabuko, inezinzuzo zokumelana nokuhlolwa kwemvelo, akukho mhlophe, ukuguquguquka okuhle, njll. Inokushisa okuphansi okuhle kakhulu, izinga lokushisa eliphezulu kanye nokumelana nomswakama ophezulu.
Isinamathiseli seglue se-UV se-SV 203 esiguquliwe se-Acrylate
I-SV 203 iyi-UV enesici esisodwa noma inhlaka ebonakalayo ekhanyisiwe. Isebenzisa kakhulu izinto eziyisisekelo zokubopha insimbi nengilazi. Isetshenziswa ekubopheni phakathi kwensimbi engagqwali, i-aluminium, kanye namapulasitiki athile abonakalayo, ingilazi yemvelo kanye nengilazi yekristalu.

Isetshenziswa kabanzi embonini yefenisha, embonini yamakhabhinethi okubonisa ingilazi, embonini yezandla zekristalu kanye nasembonini ye-elekthronikhi. Ifomula yayo ehlukile engancibilikisi. Ifaneleka embonini yefenisha yengilazi futhi ingafuthwa ngopende ngemva kokubopha. Ngeke iphenduke ibe mhlophe noma inciphe.
Xhumana ne-siway sealant ukuze ufunde kabanzi nge-UV glue!
