Umlingo "Wokukhanya": Izimfihlo Zokuphrinta Nge-UV
Wake wazibuza ukuthi kungani amaphethini asemaphaketheni kagwayi ekhanya kangaka, enezimo eziyinkimbinkimbi kanye nokuthinta okuyingqayizivele? Ngemuva kwalokhu kukhona ubuchwepheshe obumangalisayo - ukuphrinta kwe-UV! Kufana nokuphonsa isipelingi "sokusetha okusheshayo" kuyinki, okwenza ukuphrinta okuvamile kube yimilingo.
Uyinki osetshenziswa ekuphrinteni okuvamile ufana namanzi achithekile phansi, adinga isikhathi sokoma ngokwemvelo. Kodwa-ke, uyinki wokuphrinta we-UV uqukethe "abalingani abathathu abangomlingo". I-resin isebenza "njengomakhi oyingcweti", obhekene nokwakha ungqimba lwephethini oluqinile; i-reactive diluent ifana "nesithambisi", esivumela uyinki ukuthi ishelele kahle ezintweni ezahlukahlukene; futhi ingxenye ebaluleke kakhulu, i-photoinitiator, "inkinobho yokuqalisa" elinde imiyalelo.
Ngesikhathi sokuphrinta, uyinki udluliselwa kusuka epuletini lokuphrinta uye ebusweni bephepha, ipulasitiki, noma ngisho nensimbi, lapho uqala khona ukunamathela. Njengoba isisekelo sidlula ngaphansi "kwendilinga yomlingo" yesibani se-UV, kuqala ukusabela okuhle! YAGUANG Uhlelo lwe-UV njengesibonelo, ingashintshwa ukuze isetshenziswe emishinini ehlukahlukene njengokunyathelisa kwe-offset, ukunyathelisa nge-gravure, ukumboza, kanye nokunyathelisa emishinini yensimbi/ejikelezayo, isebenza njengomsizi wokunyathelisa oguquguqukayo. Kungakhathaliseki ukuthi umshini omkhulu wokunyathelisa noma idivayisi encane ejikelezayo,YAGUANGUhlelo lwe-UV luhlinzeka ngemisebe ye-UV enembile, okufeza ukuphiliswa okusheshayo.
Ukukhanya kwe-UV okuphumayo kusebenza "njengesihluthulelo somlingo", kuvula ngokushesha i-photoinitiator, "inkinobho yokuqalisa". I-photoinitiator iqondisa ngokushesha i-resin kanye ne-reactive diluent ukuthi "ibambe izandla" futhi i-polymerize ngokushesha. Ngemizuzwana engu-0.1 nje, uyinki owuketshezi wokuqala uguquka ube ifilimu eqinile, eqinile, necwebezelayo!
Lobu buchwepheshe abugcini nje ngokumisa iphethini ngokushesha kodwa futhi benza imibala ikhanye kakhulu futhi iqine, imelane nokuguguleka namanzi. Ngaphezu kwalokho, YAGUANG Uhlelo lwe-UV lusekela imithombo yokukhanya ye-UV ye-LED enobungani nemvelo. Uma iqhathaniswa nemithombo yokukhanya yendabuko, ayikhiqizi i-ozone futhi isebenzisa amandla amancane, okwenza kube "umlingo oluhlaza" eMhlabeni. Ngesikhathi esizayo uma ubona ibhokisi likagwayi elipakishwe kahle, kungani ungaqageli ukuthi liqukethe "umlingo wokukhanya" wokunyathelisa kwe-UV?
