Filim sawir leh oo loogu talagalay sifaynta saxda ah
Filimka Etched Photo
Waxay qabataa habka etching kiimikaad si ay uga baaraandegto qaabab kala duwan oo kakan oo ah mesh sax ah oo sarreeya iyo garaafyada xaashiyo bir ah oo kala duwan iyadoo loo eegayo jaantusyada joomatari ee loo qaabeeyey, kuwaas oo aan lagu dhammaystiri karin habab farsamo oo kala duwan.
Qalab
xaashi bir ah, xaashi naxaas ah, xaashi aluminium ah iyo go'yaal alloy oo kala duwan.
Mabda'a Etching
Etching waxa kale oo loo yaqaan Etching photochemical.Waxa loola jeedaa samaynta saxanka iyada oo loo marayo soo-gaadhista, ka dib korriinka, filimka difaaca ee goobta lagu dhejiyo ayaa la saaraa, goobta etching waxaa lala xiriiriyaa xal kiimiko ah si loo gaaro saameynta kala-baxa iyo daxalka si loo sameeyo qaabka iyo cabbirka loo baahan yahay.
Habka wax soo saarka
① Iska yaree saxanka birta si waafaqsan shuruudaha sawirka.
② Garaafyada naqshadeynta saxanka birta ah.
③ Diyaarso ama dooro xalal kiimiko oo kala duwan iyadoo loo eegayo agabyo kala duwan.
④ Nadiifinta saxan-qalin-qallaynta-soo-gaadhista-horumarinta-foofooyinka qallajinta-qadhka-saarista-nadiifinta iyo qalajinta.
Heerka Farsamada
① Meesha xoqista: 500mmx600mm.
② Dhumucda alaabta: 0.01mm-2.0mm, gaar ahaan ku habboon taarikada aadka u khafiifka ah ee ka hooseeya 0.5mm.
③ Dhexroorka siliga ugu yar iyo dhexroorka daloolka ugu yar: 0.01-0.03mm.
(1) Micropores waa godad wareegsan
Waxaa lagu kala soocay qaabka sawirka saxan lagu xardhay: wareegsan, semicircular, leydi, iwm.
Waxaa lagu kala saaraa dhumucda saxan sawireedka: 0.05mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, iwm.
Tilmaamo iyo cabbirro kala duwan ayaa loo habayn karaa iyadoo loo eegayo shuruudaha macaamiisha.
(2) Micropores waa dalool qaabaysan dhexda
Waxaa lagu kala soocay qaabka sawirka saxan lagu xardhay: wareegsan, semicircular, leydi, iwm.
Waxaa lagu kala saaraa dhumucda saxan sawireedka: 0.05mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, iwm.
Tilmaamo iyo cabbirro kala duwan ayaa loo habayn karaa iyadoo loo eegayo shuruudaha macaamiisha.
Astaamaha
① Saxnimo sare.
② Habaynta qaabab kala duwan oo dalool-yar oo adag.
③ Hagaajinta alaabada yaryar iyo kuwa khafiifka ah ee kala duwan.
Adeegsada
Filim sawir leh ayaa loo isticmaali karaa mesh shaandhaynta saxda ah, saxan shaandhaynta, kartoonada shaandhada iyo shaandhaynta batroolka, kiimikaadka, cuntada, dawooyinka iyo warshadaha kale.
