Ukwakhiwa kwefilimu yeibhodi camera umbalaezinengilazi ngokuyinhloko kuhlanganisa izici ezimbili: enamathela ukunamathela kanye enamathela omiswe.
Ukunamathela kwe-A color camera board coating
Isinyathelo sokuqala sokunamathela phakathi kwe-substrate ye-steel strip kanye ne-coating ukumanziswa kombala webhodi elinamekwe endaweni engaphansi. Ukumanzisa okokumboza kungangena esikhundleni somoya namanzi okwakukhangiswe ekuqaleni endaweni ye-steel strip substrate. Ngesikhathi esifanayo, i-volatilization ye-solvent endaweni ye-substrate iholela ekuhlakazeni noma ekuvuvukeni. Uma imingcele yokuncibilika kwe-resin eyenza ifilimu yombala webhodi elihlanganiswe ngombala kanye ne-substrate surface ikhethwe ngokufanele, izokwakha ungqimba olungenakuqhathaniswa phakathi kwendawo engaphansi yebhodi ehlanganiswe ngombala kanye nefilimu yokunamathela, lokhu kubalulekile ekunamatheleni okuhle ukunamathela.
Ukomiswa kwe-Bibhodi camera umbalaenamathela
Ukwakhiwa kokunamathela kombala webhodi elihlanganiswe ngombala kuqeda kuphela isinyathelo sokuqala sokubunjwa kwefilimu yokugqoka enkambweni yokugqoka ibhodi elinemibala enemibala, futhi inqubo yokuba ifilimu eqhubekayo eqinile idinga ukuqhubeka, engaqedela yonke inqubo yokubunjwa kwefilimu yokuhlanganisa. . Inqubo yokushintsha kusuka "kwifilimu emanzi" kuya "ifilimu eyomile" ngokuvamile ibizwa ngokuthi "ukoma" noma "ukwelapha". Le nqubo yokomisa nokuphulukisa iwumgogodla wenqubo yokwenza ifilimu yokuhlanganisa. Izembatho ezinamafomu ahlukene kanye nezingoma zinezinqubo zabo zokwenza ifilimu, ezinqunywa izakhiwo zezinto zokwakha ifilimu ezisetshenziselwa ukugqoka. Ngokuvamile, sihlukanisa inqubo yokwenza ifilimu yokuhlanganisa izigaba ezimbili:
(1) Ayiguquli. Ngokuvamile, kubhekiselwa endleleni yokwenza ifilimu ebonakalayo, encike kakhulu ekuvuthweni kwezincibilikisi noma eminye imithombo yezindaba ehlakazayo efilimu yokumboza, kancane kancane ikhulise i-viscosity yefilimu yokumboza futhi yakhe ifilimu eqinile yokuhlanganisa. Isibonelo, i-acrylic coatings, i-chlorinated rubber coatings, i-ethylene coatings, njll.
(2) Uguquko. Ngokuvamile, kubhekiselwa ekwenzeka kokuhlangana kwamakhemikhali phakathi nenqubo yokwenza ifilimu, futhi ukumboza kuncike kakhulu ekuhlanganeni kwamakhemikhali ukuze kwakhe ifilimu. Le nqubo yokwenza ifilimu ibhekisela ekwenziweni kwe-polymerization yezinto ezakha ifilimu ezimbotsheni, ezibizwa ngokuthi ama-polymers, ngemva kokufaka isicelo. Kungashiwo ukuthi kuyindlela ekhethekile ye-polymer synthesis, elandela ngokuphelele indlela yokusabela ye-polymer synthesis. Isibonelo, i-alkyd coatings, i-epoxy coatings, i-polyurethane coatings, i-phenolic coatings, njll. Kodwa-ke, izigqoko eziningi zanamuhla azenzi amafilimu ngendlela eyodwa, kodwa zithembele ezindleleni eziningi ukuze ekugcineni zenze amafilimu, futhi ukumbozwa kwamakhoyili kuwuhlobo olujwayelekile lwefilimu. encike ezindleleni eziningi ukuze ekugcineni enze amafilimu.
