Kho cov khoom siv roj hmab celluloid
Vim tias cov khoom tsis yooj yim thiab khoom qub ntawm cov khoom, cov roj hmab celluloid feem ntau tau txais ntau yam kev puas tsuaj: kev sib faib ntawm cov nplaum lo nplaum, dents, tawg, tawg thiab qhov. Yog tias qhov kev puas tsuaj loj, nws yog qhov zoo uas yuav tsum tau kho los ntawm tus kws tshaj lij hauv lub rooj cob qhia. Koj tuaj yeem sim kho cov teeb meem me me ntawm koj tus kheej.
Kev kho cov ntawv me: Ua kom lub ntsej muag celluloid nyob rau hauv cov dej kub heev los yog lub zog ua pa, thiab tom qab ntawd sim kho lub qhov hniav cuav ntawm lub qhov hauv lub npog tas ib ce.
Thaj ua rau thaj: hauv qee cov me nyuam roj hmab ib qho ntawm cov celluloid “dai“- cov qhov ntawm sab hauv rau txuas rau lub cev. Yog tias koj tswj maj mam rub tawm cov ntawv no nrog cov pob tw me me, tom qab ntawd lawv yuav ua rau thaj ua rau thaj chaw zoo: lawv yuav tsum tau muab tso rau hauv acetone kom mos, tom qab kua nplaum rau ntawm lub qhov thiab so qhov chaw gluing nrog ib qho pas dej hauv duav hauv acetone.
Koj tuaj yeem nplaum cov kab nrib pleb thiab cov qhov me me nrog kua nplaum ua tsev. Koj yuav xav tau cov duab tsis tsim nyog lossis zaj duab xis (celluloid), uas koj xav tau ua ntej yaug nrog dej kub ntawm dej qab zib (1/2 me me ib khob dej) kom ntxuav tawm ntawm emulsion, tom qab ntawd ntuav, muab tso rau hauv lub khob ntim thiab hliv. acetone lossis vinegar essence - 1 ntu celluloid rau 3 ntu ntawm cov kuab tshuaj.
