Isingeniso: Udaba oluphrintiwe ukukhombisa ukubaluleka kwalo ebusweni bombhalo nokuphrinta umbhalo, ukukhanya okungaphezulu kwento ephrintiwe embozwe ungqimba lwe-coating ekhanyelayo engenambala, ngemva kokulinganisa, yomiswa phezu kwento ephrintiwe ukuze yakhe into encane. kanye nongqimba olukhanyayo olukhanyayo olufanayo lobuchwepheshe bokucubungula.I-glazing ayikwazi nje ukuthuthukisa ukukhanya kwendawo ephrintiwe, ivikele umbhalo ophrintiwe, kodwa futhi ngeke ithinte ukugaywa kabusha kwephepha.Lesi sihloko sabelana ngokuqukethwe okuhlobene kwezinto ezithinta ikhwalithi ecwebezelayo yereferensi yabangane:
Ukucwebezela
Ukukhanya okungaphezulu kuhlanganiswe (noma kufafazwe, kuphrintiwe) ebusweni bendaba ephrintiwe ngesendlalelo se-coating esobala engenambala, evikela futhi yandise ukucwebezela kwento ephrintiwe ngemva kokumiswa.Ngaphezulu kwento ephrintiwe embozwe (noma ifutho, ukuphrinta) oqweqweni lwe-coating esobala engenambala, ngemuva kokulinganisa, ukomisa, ukucindezela, ukuphulukisa ebusweni bendaba ephrintiwe ukuze kwakhiwe ungqimba olukhanyayo olukhanyayo oluncane nolunye, dlala ukuze uthuthukise. ubushelelezi obuphezulu benkampani yenethiwekhi, vikela umsebenzi wokucubungula umhlobiso wokuphrinta wenqubo, owaziwa ngokuthi inqubo ye-glazing.Inqubo yokuphrinta ingahlukaniswa ibe yi-coating glazing, i-coating pressure light, i-UV glazing, i-pearlescent pigment glazing nokunye.
01 Ukufaneleka kwe-glazing
Ukufaneleka kokuphrinta kwegloss ikakhulukazi kubhekisela kumthelela wephepha lokuphrinta noyinki wokuphrinta.Isici esiyinhloko esinomthelela yi-crystallization yephepha, uyinki kanye nodaba oluphrintiwe.
1) Ukusebenza kwephepha
Izinga lokuphrinta lincike ekutheni iphepha linokufaneleka okuhle kwe-glazing.Phakathi kwazo, ukushelela nokusebenza kokumuncwa kuyisici esiyinhloko esithinta ukufaneleka kokukhanya kwephepha.
Ubushelelezi bephepha
Okubizwa ngokuthi bushelelezi, yizinga lephepha elingaphandle kokufana okubushelelezi.Lapho ubushelelezi bephepha buphezulu, ukugqoka okucwebezelayo kungathintana kahle nephepha, futhi kugeleze phansi endaweni yephepha, emva kokumisa kungakha indawo ephezulu yefilimu ebushelelezi, enomphumela omuhle we-glazing;Lapho ubushelelezi bephepha buphansi, ngenxa yokuthi ingaphezulu lephepha lukhuni, ukuhluka kwephepha lephepha eliphansi lizothatha ukugqoka kwe-glazing, ngakho-ke umphumela we-glazing awumuhle, ngenxa yalokhu kusilela, kufanele kuqala kuhlanganiswe ungqimba lwe-glazing. okunamathelayo ebusweni bendaba ephrintiwe bese kuba yi-glazing.
Impahla yokumuncwa kwephepha
Okubizwa ngokuthi ukusebenza kokumuncwa, njengoba negama lisho, yizinto zokuxhuma uyinki yokumuncwa kanye nokusebenza kwe-solvent.I-capillary absorbability kanye nokungabi bikho kwefayibha yephepha kunquma ukuthi indawo yephepha inokumuncwa okuqinile yini.Lapho iphepha linezakhiwo eziqinile zokumunca, lizokwandisa i-viscosity ye-glazing coating.Ngakho, impahla yokulinganisa iyancipha;Ngokuphambene nalokho, lapho impahla yokumunca yephepha ibuthakathaka, khona-ke i-viscosity yokugcoba i-gloss ngeke ikhule ngenxa yokomisa.Lokhu kwenza ukuqina, ukuqina kanye nokusebenza kwe-conjunctiva kwehle, kunzima ukwakha ifilimu enhle ebusweni bendaba ephrintiwe.Ukuze sixazulule le nkinga, kufanele selule isikhathi sokulinganisa futhi sandise izinga lokushisa lokumisa ukuze sithuthukise ikhwalithi yokucwenga.
