I. mazwi
Chiedza chependi resolution: inoreva kuti mangani mapoinzi anogona kuiswa mune imwe inch kureba; chikwata: PDI
Optical density: inoreva huwandu hwemasirivheri akaderedzwa mu emulsion firimu, ndiko kuti, kugona kuvharira mwenje, iyo unit ndeye "D", iyo fomula: D = lg (chiitiko chiedza simba / transmitted chiedza simba)
Gamma: Gamma inoreva dhigirii iyo dhizaini yekuona kweiyo yakaipa firimu inoshanduka mushure mekuiswa pasi pekusimba kwakasiyana kwechiedza?
II. Kuumbwa uye basa rechiedza chekupenda firimu
1 nzvimbo yepamusoro:
Inobata basa mukudzivirira kukwenya uye inodzivirira sirivheri munyu emulsion layer kubva pakukuvadzwa!
2.Drug firimu (sirivha munyu emulsion layer)
Muchikamu chemufananidzo, izvo zvakakosha zve emulsion isirivha bromide, sirivheri chloride, sirivheri iodide uye imwe sirivheri yemunyu photosensitive zvinhu, pamwe negelatin uye pigment inogona kudzoreredza simbi yepakati pasi pekuita kwechiedza. Asi munyu wesirivha hauna kunyungudika mumvura, saka gelatin inoshandiswa kuita kuti ive yakasimirirwa mamiriro uye yakaputirwa pachigadziko chefirimu. Iyo pigment iri mu emulsion inotamba sensitizing mhedzisiro.
3. Adhesive layer
Kurudzira kunamatira kwe emulsion layer kune iyo firimu base. Kuti uvandudze simba rekubatanidza pakati pe emulsion uye nheyo yefirimu, aqueous solution yegelatin uye chrome alum inoshandiswa sevhavha yekubatanidza kuti iite zvakasimba.
4. Polyester base layer
Inotakura firimu base uye isina kunaka firimu base inowanzo shandisa nitrocellulose, acetate kana polyester firimu base. Mhando mbiri dzekutanga dzemabhesi emufirimu ane kuchinjika kukuru, uye saizi yepolyester film base haina kugadzikana.
5. Anti-halo / static layer
Anti-halo uye static magetsi. Mumamiriro ezvinhu akajairwa, nzvimbo yepasi peiyo firimu base inoratidzira mwenje, ichiita kuti emulsion layer inzwisiswe zvakare kugadzira halo. Kudzivirira halo, mhinduro ine mvura yegelatin plus basic fuchsin inoshandiswa kupfekedza kumashure kweiyo firimu base kuti itore mwenje. Inonzi anti-halation layer.
III, maitiro ekushanda kwechiedza chekupenda firimu
1. Chiedza chekupenda
Kupenda kwechiedza chaizvoizvo inzira yechiedza. Mushure mokunge firimu iri pachena, munyu wesirivha unodzorera nzvimbo yesirivha, asi panguva ino, hapana mifananidzo inogona kuonekwa pafirimu, iyo inonzi latent image. Michina yemwenje inowanzoshandiswa ndeiyi: flat-panel laser light drawing machines, Inner barrel type laser light plotter, outer barrel type laser light plotter, etc.
2. kukura
Iyo sirivheri munyu mushure mekuvhenekera inoderedzwa kuita dema sirivheri zvimedu. Kupisa kwemugadziri ane simba guru pakukurumidza kwekusimudzira. Iyo yakakwirira tembiricha, iyo inokurumidza kukurumidza kukurumidza. Iyo yakakodzera tembiricha yekukura i18℃～25℃. Izvo zvikamu zvikuru zvemumvuri wemvura zvinoumbwa nemugadziri, anodzivirira, accelerator uye inhibitor. Mabasa ayo ndeaya anotevera:
1) .Developer : Basa remugadziri nderokuderedza photosensitive sirivheri munyu kune sirivheri.Naizvozvo, mugadziri ari zvakare inoderedza mumiririri. Makemikari anowanzo shandiswa seanoderedza anosanganisira hydroquinone uye p-cresol sulfate.
2). Chidziviriro mumiriri: Iyo inodzivirira inodzivirira mugadziri kubva kune oxidizing, uye sodium sulfite inowanzoshandiswa seanodzivirira.
3) .Accelerator: Accelerator chinhu che alkaline chine basa rekumhanyisa budiriro. Inowanzo shandiswa accelerators sodium carbonate, borax, sodium hydroxide, nezvimwewo, iyo sodium hydroxide ndiyo yakasimba accelerator.
4). Inhibitor: Basa re inhibitor ndere kurambidza kudzikiswa kwesirivheri yakareruka munyu kune sirivheri, izvo zvinogona kudzivirira chikamu chisina kuvhenekerwa kubva pakuburitsa mhute panguva yekuvandudza. Potassium bromidi inhibitor yakanaka, uye ine simba refotosensitive Nzvimbo dzinodzivirirwa zvisina simba, uye nzvimbo dzisina kusimba kwechiedza chakasimba.
IV. Kugadzirisa
Shandisa ammonium thiosulfate kuti ubvise munyu wesirivha usina kuderedzwa kuva sirivheri, kana zvisina kudaro chikamu ichi chemunyu chesirivha chichabudiswa zvakare, kuparadza chifananidzo chepakutanga.
