II. Abun da ke ciki da aikin fim din zanen haske
Layer na 1:
Yana taka rawa wajen hana karce kuma yana kare layin emulsion na gishiri na azurfa daga lalacewa!
2.Drug film (azurfa gishiri emulsion Layer)
A cikin hoton hoton, babban abubuwan da ke cikin emulsion sune bromide na azurfa, chloride na azurfa, iodide na azurfa da sauran abubuwa masu ban sha'awa na gishiri na azurfa, da gelatin da pigments waɗanda zasu iya mayar da cibiyar cibiyar azurfa a ƙarƙashin aikin haske. Amma gishirin azurfa ba shi da narkewa a cikin ruwa, don haka ana amfani da gelatin don sanya shi cikin yanayin da aka dakatar kuma an rufe shi a kan tushen fim. Alamun da ke cikin emulsion yana taka rawar gani.
3. M Layer
Haɓaka mannewa na emulsion Layer zuwa gindin fim. Don haɓaka ƙarfin haɗin gwiwa tsakanin emulsion da tushe na fim, ana amfani da maganin ruwa na gelatin da chrome alum azaman haɗin haɗin gwiwa don sanya shi da ƙarfi.
4. Polyester tushe Layer
Tushen fim ɗin mai ɗaukar hoto da tushe mara kyau na fim gabaɗaya suna amfani da nitrocellulose, acetate ko tushen fim ɗin polyester. Nau'o'in fina-finai guda biyu na farko suna da babban sassauci, kuma girman tushen fim ɗin polyester yana da inganci.
5. Anti-halo/static Layer
Anti-halo da wutar lantarki a tsaye. A ƙarƙashin yanayi na al'ada, ƙasan filin fim ɗin hoto zai nuna haske, yana sa Layer emulsion ya sake fahimtar da shi don samar da halo. Don hana halo, ana amfani da maganin ruwa na gelatin tare da fuchsin na asali don shafa bayan gindin fim don ɗaukar haske. Ana kiran sa Layer anti-halation.
III, tsarin aiki na fim din zanen haske
1. Zane mai haske
Zanen haske shine ainihin tsari mai haske. Bayan an fallasa fim ɗin, gishirin azurfa ya dawo da cibiyar azurfa, amma a wannan lokacin, ba za a iya ganin hotuna akan fim ɗin ba, wanda ake kira hoton ɓoye. Na'urorin hasken da aka fi amfani da su sune: na'urorin zana haske mai lebur-panel, nau'in ganga na ciki irin na'urar hasken wutar lantarki, nau'in nau'in hasken wuta na waje, da dai sauransu.
2. tasowa
Gishirin azurfa bayan haske yana raguwa zuwa barbashi na azurfa baki. Yanayin zafin jiki na mai haɓaka yana da tasiri mai girma akan saurin ci gaba. Mafi girman zafin jiki, saurin ci gaba da sauri. Madaidaicin zafin jiki mai tasowa shine 18 ℃ ~ 25 ℃. Babban abubuwan da ke cikin ruwan inuwa sun ƙunshi mai haɓakawa, mai karewa, mai haɓakawa da hanawa. Ayyukansa sune kamar haka:
1) Mai haɓakawa: Aikin mai haɓakawa shine ya rage gishirin azurfa mai ɗaukar hoto zuwa azurfa.Saboda haka, mai haɓakawa kuma wakili ne na ragewa. Sinadaran da aka saba amfani da su azaman masu ragewa sun haɗa da hydroquinone da p-cresol sulfate.
2). Wakilin kariya: Wakilin kariya yana hana mai haɓakawa daga oxidizing, kuma ana amfani da sodium sulfite a matsayin wakili mai kariya.
3).Accelerator: Accelerator wani abu ne na alkaline wanda aikinsa shine haɓaka ci gaba. Accelerators da aka saba amfani da su sune sodium carbonate, borax, sodium hydroxide, da dai sauransu, wanda sodium hydroxide ke da ƙarfi mai ƙarfi.
4). Mai hanawa: Matsayin mai hanawa shine hana raguwar gishirin azurfa mai haske zuwa azurfa, wanda zai iya hana ɓangaren da ba shi da haske daga haifar da hazo yayin haɓakawa. Potassium bromide shine mai hanawa mai kyau, kuma yana da ƙarfi mai ɗaukar hoto.
IV. Gyarawa
Yi amfani da ammonium thiosulfate don cire gishirin azurfa wanda ba a rage shi zuwa azurfa ba, in ba haka ba wannan ɓangaren gishiri na azurfa zai sake bayyana, ya lalata ainihin hoton.
