I. isigama
Isisombululo sokupeyinta ukukhanya: kubhekiselele ekubeni mangaphi amanqaku anokubekwa kwi-intshi enye ubude; iyunithi: PDI
Ubuninzi be-Optical density: ibhekisela kwisixa seencinci zesilivere ezincitshisiweyo kwifilimu ye-emulsion, oko kukuthi, ukukwazi ukuvimba ukukhanya, iyunithi "D", i-formula: D = lg (isiganeko samandla okukhanya / ukuhanjiswa kwamandla okukhanya)
I-Gamma: I-Gamma ibhekiselele kwinqanaba apho ukuxinana kwe-optical yefilimu engalunganga kutshintsha emva kokuba phantsi kobunzima obahlukeneyo bokukhanya?
II. Ukubunjwa kunye nomsebenzi wefilimu yokudweba ukukhanya
1 umaleko womphezulu:
Idlala indima ekuthinteleni imikrwelo kwaye ikhusela umaleko we-emulsion yetyuwa yesilivere ukuba wonakaliswe!
2.Ifilimu yeziyobisi (isilivere ye-emulsion layer)
Kumaleko womfanekiso, amacandelo aphambili e-emulsion yibromide yesilivere, i-chloride yesilivere, i-iodide yesilivere kunye nezinye izinto zesilivere ze-photosensitive, kunye ne-gelatin kunye neepigments ezinokubuyisela iziko eliphambili lesilivere phantsi kwesenzo sokukhanya. Kodwa ityuwa yesilivere ayinyibiliki emanzini, ngoko i-gelatin isetyenziselwa ukuyenza ibe yindawo emisiwe kwaye ifakwe kwisiseko sefilimu. I-pigment kwi-emulsion idlala umphumo obonakalayo.
3. Umaleko wokuncamathelisa
Ukukhuthaza ukunamathela kwe-emulsion layer kwisiseko sefilimu. Ukuze kuphuculwe amandla okubambisana phakathi kwe-emulsion kunye nesiseko sefilimu, isisombululo esinamanzi se-gelatin kunye ne-chrome alum sisetyenziswa njengoluhlu lwe-bonding ukuze luqiniswe ngokuqinileyo.
4. Umaleko wesiseko sepolyester
Isiseko sefilimu ye-Carrier kunye nesiseko sefilimu esibi ngokuqhelekileyo sisebenzisa i-nitrocellulose, i-acetate okanye isiseko sefilimu ye-polyester. Iindidi ezimbini zokuqala zeziseko zefilimu zinokuguquguquka okukhulu, kwaye ubungakanani besiseko sefilimu yepolyester buzinzile.
5. Umaleko we-Anti-halo / static
I-Anti-halo kunye nombane omileyo. Ngaphantsi kweemeko eziqhelekileyo, umgangatho ophantsi wesiseko sefilimu yezithombe uya kubonakalisa ukukhanya, okwenza i-emulsion layer ivakaliswe kwakhona ukuvelisa i-halo. Ukuthintela i-halo, isisombululo esinamanzi se-gelatin kunye ne-fuchsin esisiseko sisetyenziselwa ukugqoka ngasemva kwesiseko sefilimu ukuze kufakwe ukukhanya. Ibizwa ngokuba yi-anti-halation layer.
III, inkqubo yokusebenza kwefilimu yokudweba ukukhanya
1. Ukupeyinta ukukhanya
Ukupeyinta ukukhanya ngokwenene kuyinkqubo yokukhanya. Emva kokuba ifilimu ibonakaliswe, ityuwa yesilivere ibuyisela iziko lesilivere, kodwa ngeli xesha, akukho mizobo ingabonwa kwifilimu, ebizwa ngokuba ngumfanekiso ofihlakeleyo. Oomatshini bokukhanya abaqhelekileyo abasetyenziswayo zezi: i-flat-panel laser light drawing machines, i-Inner barrel type laser light plotter, umgqomo wangaphandle uhlobo lwe-laser light plotter, njl.
2. ukuphuhlisa
Ityuwa yesilivere emva kokukhanyisa iyancitshiswa ibe ngamasuntswana esilivere amnyama. Ubushushu bomphuhlisi bunempembelelo enkulu kwisantya sophuhliso. Ukuphakama kweqondo lokushisa, ngokukhawuleza isantya sophuhliso. Ubushushu bokukhula obufanelekileyo yi-18℃～25℃. Amacandelo aphambili olwelo lwesithunzi aqulunqwe ngumphuhlisi, umkhuseli, i-accelerator kunye ne-inhibitor. Imisebenzi yayo imi ngolu hlobo lulandelayo:
1) .Umphuhlisi: Umsebenzi womphuhlisi kukunciphisa ityuwa yesilivere ye-photosensitive kwisilivere.Ngoko ke, umphuhlisi naye uyi-arhente yokunciphisa. Iikhemikhali eziqhele ukusetyenziswa njengeejenti zokunciphisa ziquka i-hydroquinone kunye ne-p-cresol sulfate.
2). I-agent ekhuselayo: I-agent ekhuselayo ikhusela umthuthukisi kwi-oxidizing, kwaye i-sodium sulfite isoloko isetyenziswa njenge-agent ekhuselayo.
3) .I-Accelerator: I-Accelerator yinto ye-alkaline umsebenzi wayo kukukhawulezisa uphuhliso. I-accelerators esetyenziswa ngokuqhelekileyo i-sodium carbonate, i-borax, i-sodium hydroxide, njl., apho i-sodium hydroxide i-accelerator enamandla.
4). I-inhibitor: Indima ye-inhibitor kukuthintela ukunciphisa ityuwa yesilivere ekhanyayo kwisilivere, enokuthintela inxalenye engakhanyiyo ekuveliseni inkungu ngexesha lophuhliso. I-Potassium bromide sisithinteli esilungileyo, kwaye ine-photosensitive eyomeleleyo
IV. Ukulungisa
Sebenzisa i-ammonium thiosulfate ukususa ityuwa yesilivere engancitshiswanga ibe yisilivere, ngaphandle koko le nxalenye yetyuwa yesilivere iya kubonakaliswa kwakhona, itshabalalise umfanekiso wokuqala.
