Amandla Okuphulukisa kwe-UV: Ukuvuselela Ukukhiqiza Ngesivinini kanye Nempumelelo

I-UV photopolymerization, eyaziwa nangokuthi ukwelapha ngemisebe noma ukwelapha kwe-UV, ubuchwepheshe obushintsha umdlalo obulokhu buguqula izinqubo zokukhiqiza cishe izingxenye ezintathu kwezine zekhulunyaka. Le nqubo emisha isebenzisa amandla e-ultraviolet ukushayela ukuphambana ngaphakathi kwezinto ezenziwe nge-UV, njengoyinki, ama-coatings, izinto zokunamathisela, nezinsimbi.

Enye yezinzuzo ezibalulekile zokwelashwa kwe-UV yikhono layo lokukhiqiza izinto ezibonakalayo ezifiseleka kakhulu ngokufakwa kwezinyawo ezinesivinini esikhulu. Lokhu kusho ukuthi izinto ezisetshenziswayo zingaguqulwa zisuke esimweni esimanzi, esiwuketshezi ziye esimweni esiqinile, esomile cishe ngaso leso sikhathi. Lokhu kuguqulwa okusheshayo kufinyelelwa ngaphandle kwesidingo sezithwali ze-liquid, ezivame ukusetshenziswa emanzini avamile kanye nokwakhiwa okusekelwe ku-solvent.

Ngokungafani nezinqubo zokomisa zendabuko, ukwelapha kwe-UV akumane kuhwamuke noma komise izinto. Kunalokho, kuba nokusabela kwamakhemikhali okwenza izibopho eziqinile, ezihlala isikhathi eside phakathi kwama-molecule. Lokhu kubangela izinto eziqine ngendlela emangalisayo, ezimelana nokulimala kwamakhemikhali nesimo sezulu, futhi ezinezindawo ezifiselekayo ezingaphezulu njengokuqina nokumelana nokushelela.

Ngokuphambene, ukwakhiwa kwamanzi okuvamile kanye ne-solvent-based kuncike ezithwali eziwuketshezi ukuze kube lula ukusetshenziswa kwezinto endaweni. Uma isisetshenzisiwe, isithwali kufanele sihwamuke noma somiswe kusetshenziswa ohhavini abadla amandla kanye namahubhu okomisa. Le nqubo ingashiya izinsalela eziqinile ezijwayele ukuklwebheka, zonakale kanye nokulimala kwamakhemikhali.

Ukwelashwa kwe-UV kunikeza izinzuzo ezimbalwa ezibalulekile kunezinqubo zokomisa zendabuko. Kokunye, kuqeda isidingo samahhavini adla amandla kanye namahubhu okomisa, kunciphisa ukusetshenziswa kwamandla kanye nomthelela wemvelo. Ukwengeza, ukuphulukiswa kwe-UV kususa isidingo sama-volatile organic compounds (VOCs) kanye nezinto ezingcolisa umoya eziyingozi (HAPs), okwenza kube inketho evumelana nemvelo.

Kafushane, ukwelapha kwe-UV kuwubuchwepheshe obusebenza kahle kakhulu obunikeza izinzuzo eziningi kubakhiqizi. Ikhono layo lokukhiqiza izinto ezisezingeni eliphezulu ngesivinini nangokunemba likwenza kube ukukhetha okuhle kwezimboni eziningi. Ngokusebenzisa amandla okwelapha e-UV, abakhiqizi bangakhiqiza izinto ezisebenza kangcono, ukubukeka, nokuqina, kuyilapho futhi behlisa umthelela wazo kwezemvelo.
