Gariiradda dahaarka midabku waxay ka kooban tahay jaakad sare, asal, dahaar, substrate iyo rinji danbe.
Dhameystir rinjiga:ka ilaali qorraxda, ka ilaali waxyeelada ultraviolet ee daaha;Marka dhammayntu gaadho dhumucda la cayimay, waxay samayn kartaa filim gaashaan ah oo cufan, taas oo yaraynaysa qulqulka biyaha iyo ogsijiinta.
Hordhac:waxaa faa'iido leh in la xoojiyo adhesion ee substrate-ka, si desorbation rinjiga ma fududa in ay dhacdo ka dib markii filimka la dhex galiyey biyo, iyo waxa ay sidoo kale hagaajin doonaa caabbinta daxalka, sababtoo ah primer ka kooban yahay daxalka inhibitor pigments, sida pigments chromate. si anode-ku u dhaafo oo caabbinta daxalka loo hagaajiyo.
Dahaarka:guud ahaan galvanized ama aluminium zinc plating, qaybtan ka mid ah nolosha adeegga ee alaabtu waxay leedahay saameynta ugu weyn, dhumucdiisuna waa, ka sii wanaagsan iska caabinta daxalka.
Substrate:guud ahaan saxan qabow oo duuban, xoog kala duwan ayaa go'aamisa sifooyinka farsamada ee saxanka dahaarka leh.
Rinjiga dhabarka:Shaqadu waa in laga hortago daxalka birta gudaha gudaha, guud ahaan laba lakab oo qaab-dhismeedka ah (2/1M ama 2/2, primer + rinjiga dhabarka), haddii dhabarku u baahan yahay in lagu xidho, waxaa lagula talinayaa in la isticmaalo qaab dhismeed hal lakab ah. (2/1).
Habka daxalka gariiradda birta midabka dahaarka leh:
Dahaarka dahaarka, daahan midabka, daahan budo, daahan xumbo dildilaaca, cad / casaan - - - - - khadka goynta ee miridhku diiray - gooyay - meel daahan off - - - - - meel weyn oo miridhku, miridhku cas deegaanka - saxan. - saxan daloolin daxalka failure.
Habka fashilka ee saxan bir ah oo midab leh ayaa lagu muujiyay sawirka kore.Dahaarka oo xumaada, dahaarka oo xumaada iyo daloolista saxanka birta ayaa ah hababka daxalka ee muhiimka ah.Sidaa darteed, kordhinta dhumucda dahaarka iyo isticmaalka cimilada iyo daahan u adkaysta ayaa ah habka ugu waxtarka badan ee looga hortago burburka daxalka saxan bir ah oo midab leh.
