Surley waa ururindaaweynta ka hor iyo hababka electrophoresis buufin foornada habka gudbinta kursiga tijaabada qubeyska farsamada ilaalinta deegaanka Agabka goobta shaqadastyle oo dhan hal dukaan.
Qalab kala duwan iyo alaabooyinkooda habka farsamaynta, gaadiidka, kaydinta, dusha sare waa sahlan tahay in la soo saaro ama
ku dheji walxaha shisheeye, sida mashiinka mashiinka, maqaarka oksaydhka, saliidda, iwm., wasakhooyinka dusha sare waxay saameyn doonaan cufnaanta dahaarka iyo xoogga isku xirnaanta ee matrixka. Dahaarka pretreatment ee ugu muhiimsan Ujeeddada waa in laga saaro walxahan iyo in la sameeyo beddelka kiimikada dusha ku habboon si ay u bixiyaan shuruudahaCoating ku habboon ee substrate ah, si loo kordhiyo adhesion ee filimka, dheereeyo nolosha adeegga filimka, Siiso ciyaar buuxda si ay u difaaca. saamaynta iyo saamaynta qurxinta ee daahan.
Sidaa darteed, buufin waxa ku jira ka hor farsamaynta. Inta badan waxa ka mid ah dhinacyada soo socda:
filimka phosphating wuxuu awooday inuu bixiyo saldhig aad u habboon oo loogu talagalay daaha rinjiga, waxaa sabab u ah saameynta soo socota:
1) Waxay siisaa nadiif, lebis, oogada dufanka la'aan ah iyada oo ku saleysan xaalufinta dhammaystiran
2) waxay wanaajisaa adhesion of film organic in substrate ay sabab u tahay ficil jirka iyo kiimikaad Ma aha wax adag in la fahmo in qaab-dhismeedka dalool ee filimka fosfooraska kordhiyaa aagga dusha sare ee substrate ah, si meesha xidhiidhka ka dhexeeya labada kordho u dhigma, iyo faa'iidada wadaagga ah ee faa'iidada leh ee u dhexeeya labada lakab ee filimka ayaa la soo saaray. Isla mar ahaantaana, isdhexgalka kiimikaad ee u dhexeeya resin aan saturated iyo crystal phosphate waxay sidoo kale kor u qaadaysaa xooggeeda xidhitaanka
3) waxay bixiyaan lakab go'doon ah oo xasilloon oo aan fiicneyn, hal mar dhaawaca daahan, waxay leedahay doorka xakamaynta daxalka, gaar ahaan jeexitaanka anode Qodobka ugu horreeya ayaa badanaa la dayacay Kaliya si buuxda ugu fiican saliidda si loo sameeyo filim fosfit ah oo ku qanacsan sidaas darteed. Filimka fosfatka laftiisa ayaa ah saameynta ugu dareensan ee tignoolajiyada pretreatment ee ugu kalsoonida badan ee is-hubinta.
