Kev Lag Luam Gelatin Ua Raws Li Tus phab ej zais hauv Kev Tsim Khoom Ntau Yam
Cov khoom lag luam gelatin thiab lawv cov ntawv thov
Daim ntawv duab thiab zaj duab xis:
Hauv kev thaij duab ib txwm muaj, cov gelatin kev lag luam siv rau hauv kev tsim cov ntawv thaij duab thiab zaj duab xis. Ua tus nqa khoom rau cov emulsion photosensitive, nws tuaj yeem faib cov tshuaj photosensitive xws li nyiaj halide kom sib npaug, ua kom cov duab zoo.
Cov nplaum taub hau sib phim:
Cov gelatin siv tau los ua kom cov taub hau ntawm cov ntais ntawv lo rau kom ntseeg tau tias muaj kev nyab xeeb thiab ntseeg tau ntawm cov ntais ntawv. Nws cov khoom nplaum zoo heev ua rau cov ntais ntawv ruaj khov dua thaum siv.
Cov nplaum:
Cov gelatin hauv kev lag luam siv tau los ua ntau yam nplaum. Cov nplaum ntuj thiab tsis muaj tshuaj lom yeej ib txwm nyiam los ntawm cov kws tshaj lij. Lawv kuj siv rau hauv kev xa ntawv - piv txwv li, cov nplaum ntawm cov ntawv xa ntawv thiab cov ntawv xa ntawv yog coated nrog dextrin, uas yog ib qho kev siv ntuj tsim.
Gelatin siv tau ua cov nplaum rau cov ntaub nplaum, muab kev nplaum zoo thiab ruaj khov, thiab tsim nyog rau ntau yam khoom siv ntaub nplaum rau kev siv hauv kev lag luam thiab hauv tsev.
Ua ib qho nplaum uas tsis ua rau ib puag ncig puas tsuaj, gelatin yog siv dav hauv kev sib txuas ntoo thiab kev sib dhos rooj tog. Nws cov khoom nplaum zoo heev ua kom cov qauv ruaj khov thiab ruaj khov ntawm cov rooj tog.
Kev kho mob gauze:
Gelatin siv tau rau kev kho thiab txheej ntawm daim ntaub qhwv, ua kom nws lub zog thiab ruaj khov thaum tseem tswj nws qhov mos thiab ua pa tau, ua rau nws tsim nyog rau kev kho mob thiab cov khoom siv tu cev.
Cov kua luam ntawv:
Ua ib qho thickener thiab nplaum, gelatin tuaj yeem txhim kho qhov fluidity thiab adhesion ntawm cov luam ntawv inks, xyuas kom meej tias qhov luam ntawv zoo thiab haum rau ntau yam ntaub ntawv luam ntawv.
Daim Ntawv:
Ntxiv cov gelatin rau kev lag luam rau kev ntsuas qhov loj thaum lub sijhawm ua ntawv tuaj yeem txhim kho qhov tsis kam dej, lub zog, thiab qhov ci ntsa iab ntawm daim ntawv, thiab txhim kho kev luam ntawv thiab kev sau ntawv.
Cov txheej txheem:
Gelatin siv tau ua ib txheej rau saum npoo ntawm cov rooj tog, muab kev ci ntsa iab thiab kev tiv thaiv, thiab txhim kho qhov zoo li thiab kev tiv thaiv kev hnav ntawm cov rooj tog. Thaum lub sijhawm luam ntawv, gelatin siv tau ua txheej rau saum npoo, txhim kho qhov ci ntsa iab thiab kev tiv thaiv kev hnav ntawm cov khoom luam tawm thiab txhim kho qhov zoo li tag nrho ntawm cov khoom. Hauv kev tsim cov ntaub nplaum, gelatin siv tau ua ib txheej rau kev txhim kho qhov tsis kam dej thiab kev tiv thaiv kev hnav ntawm cov ntaub nplaum. Gelatin kuj tseem siv tau ua ib txheej rau cov ntais ntawv, muab kev tiv thaiv ntxiv tiv thaiv dej noo thiab oxidation.
