I. terminology
Ukulungiswa kokudweba okukhanyayo: kubhekiselwa emaphuzu amangaki afakwe kubude obuningi be-intshi; Iyunithi: PDI
Ubuningi be-Optical: kubhekiswa inani lezinhlayiya zesiliva elincishisiwe kwifilimu ye-emulsion, okungukuthi, amandla okuvimba ukukhanya, iyunithi yi- "D = LG (D = LG (I-Elevent Light Energy Energy / Amandla akhanyayo)
UGamma: UGamma ubhekisela ezingeni lapho ubuningi bokukhanya kwefilimu elingezinhle kuguquka ngemuva kokuqina kokukhanya okuhlukile?
II. Ukwakheka kanye nomsebenzi wefilimu lokudweba ukukhanya
1 ungqimba ongaphezulu:
Idlala indima ekuvimbeleni imihuzuko futhi ivikele isiliva emulsion ungqimba kusuka ekulimaleni!
Ifilimu le-2.Rug (isiliva usawoti emulsion ungqimba)
Esithombeni, izingxenye eziphambili ze-emulsion ziyisiliva i-bromide yesiliva, i-chloride yesiliva, i-iodide yesiliva nezinye izinto zesiliva ezishisayo, kanye ne-gelatin engabuyisela isikhungo sesiliva esiyisisekelo ngaphansi kwesenzo sokukhanya. Kepha usawoti wesiliva awunamehlo emanzini, ngakho-ke i-gelatin isetshenziselwa ukuyenza ibe yisimo esimisiwe futhi ihlanganiswe esisekelweni sefilimu. I-pigment emulsion idlala umphumela ozwakalayo.
3. Ungqimba olunamathela
Gqugquzela ukunamathela kwe-emulsion ungqimba kwisisekelo sefilimu. Ukuze uthuthukise amandla okubopha phakathi kwe-emulsion kanye nesizinda sefilimu, isisombululo esinamanzi se-gelatin ne-chrome alum sisetshenziswa njengesendlalelo se-bonding ukuyenza iboshwe ngokuqinile.
4. Isendlalelo se-Polyester base
Isizinda sefilimu ethwala kanye nesizinda sefilimu esingesihle ngokuvamile sisebenzisa i-NitroCellulose, i-Acetate noma i-Polyester Film Base. Izinhlobo ezimbili zokuqala zezisekelo zefilimu zinokuguquguquka okukhulu, kanti usayizi we-polyester film base uzinzile
I-5. Anti-halo / ungqimba lwe-tuli
I-Anti-Halo kanye nogesi ophelele. Ngaphansi kwezimo ezijwayelekile, ingaphezulu lesizinda sefilimu elinezithombe kuzobonisa ukukhanya, okwenza ungqimba lwe-emulsion luphinde lwandiswe ukukhiqiza i-halo. Ukuvimbela i-halo, ikhambi elinamanzi le-gelatin plus fuchsin eziyisisekelo lisetshenziselwa ukumboza emuva kwesisekelo sefilimu ukudonsa ukukhanya. Ibizwa ngokuthi ungqimba lwe-anti-hamation.
I-III, inqubo yokusebenza yefilimu yokudweba ukukhanya
1. Ukudweba okukhanyayo
Umdwebo okhanyayo empeleni uyinqubo ekhanyayo. Ngemuva kokuba ifilimu iveziwe, usawoti wesiliva ubuyisela isikhungo sesiliva, kepha ngalesi sikhathi, akukho zithombe ezingabonakala kwifilimu, ebizwa ngokuthi isithombe sangemuva. Imishini elula esetshenziswayo yilena: Imishini yokudweba ye-Laser-Panel Laser Light Light, uhlobo lwangaphakathi lwe-barnel laser ukukhanya, uhlobo lwangaphandle lwe-barrel lohlobo lwe-laser light plotter, njll.
2. Ukuthuthuka
Usawoti wesiliva ngemuva kokukhanyisa kuncishiswa izinhlayiya zesiliva ezimnyama. Izinga lokushisa lonjiniyela linethonya elikhulu kwijubane lokuthuthukisa. Ukushisa okuphezulu, ijubane lentuthuko ngokushesha. Izinga lokushisa elifanelekile lingu-18 ℃ ~ 25 ℃. Izici eziphambili ze-Shadow Fluid zakhiwa unjiniyela, umvikeli, i-accelerator ne-inhibitor. Imisebenzi yayo imi ngalendlela elandelayo:
1) .Developer: Umsebenzi wonjiniyela ukunciphisa usawoti wesiliva we-photosensitive isiliva Amakhemikhali asetshenziswa kakhulu njengoba ukunciphisa ama-ejenti afaka i-hydroquinone kanye ne-p-cresol sulfate.
2). I-ejenti evikelayo: I-ejenti evikelayo ivimbela onjiniyela kusuka ku-oxidizing, futhi i-sodium sulfite ivame ukusetshenziswa njenge-ejenti evikelayo.
3) .Accelerator: I-Accelerator iyinto ye-alkaline into esebenza kuyo ukusheshisa ukuthuthuka. Ama-accelerators asetshenziswa kakhulu yi-sodium carbonate, i-borax, i-sodium hydroxide, njll., Lapho i-sodium hydroxide iyisivinini esinamandla.
4). I-Inhibitor: Iqhaza le-inhibitor ukuvimbela ukuncishiswa kosawoti wesiliva esiliva kuya esiliva, okungavimba ingxenye ebikholwe ekukhiqizweni kwenkungu ngesikhathi sokuthuthuka. I-Potassium Bromide iyi-inhibitor enhle, futhi inezindawo eziqinile zezithombe zivinjelwe buthaka, futhi izindawo ezinokuzwela okukhanyayo ziqinile.
IV. Ukuhlela
Sebenzisa i-ammonium thiesulfate ukususa usawoti wesiliva ongancishisiwe kube yisiliva, ngaphandle kwalokho le ngxenye kasawoti wesiliva izophinde ivezwe futhi, ichithe isithombe sokuqala.
