Habka wax-soo-saarka asaasiga ah ee xaashida aluminium-ka-midabka leh ee dahaarka leh waa sida soo socota: Marka hore, gariiradda aluminiumka ee dhammaatay waxay martaa hoos u dhigista alkaline iyo daaweynta basbaaska. Dhaqida alkaline waxay ka saartaa saliidaha rogmanaya iyo wasakhda dusha aluminiumka si loo xaqiijiyo ku dhegganaanta. Passivation waxay samaysaa filim difaac cufan oo ku saabsan substrate aluminium, kor u qaadista iska caabbinta daxalka iyo xidhiidhka ka dhexeeya substrate iyo daahan; ka dib daawayn ka dib, dusha xaashida ayaa la eegayaa si loo hubiyo in aanay saliid lahayn iyo wasakhda haraaga ah ka hor inta aan loo sii gudbin heerka daahan Habka caadiga ah "laba jaakad, laba-dubi" (habka caadiga ah): Koodhka koowaad: daahan rullaluistemadka koowaad ah + marxaladda dubista koowaad Asal gaar ah oo kor u qaada adhesion ayaa lagu dabaqaa daahan rullaluistemadka ah oo dhumucdiisuna tahay 5-8 μm. Walaxda ayaa markaa gasha xariiqda dubista waxaana lagu daaweeyaa 200-240 ° C 30-60 ilbiriqsi si loo hubiyo in curiyaha si buuxda u bogsado iyo si kor loogu qaado xidhiidhka ka dhexeeya dusha sare iyo substrate-ka. Jaakad Labaad: Dahaarka dusha sare ee dahabka ah + marxaladda dubista labaad Daahaarka dahabiga ah ee la diyaariyey (oo lagu sameeyay polyester-ka caadiga ah, adkeysiga sare ee HDP, ama resin fluorocarbon oo ay weheliso luul dahab ah ama pigments dahabka ah) ayaa si siman loogu dabaqayaa aasaaska iyada oo loo marayo dahaarka rullaluistemadka oo ah dhumuc dhan 10-15 μm. Maaddadu waxay mar kale gashaa foornada si ay u daaweyso 220-260 ° C, taas oo u oggolaanaysa daaha dahabka ah inuu si buuxda isku xiro oo hubiyo mid lebbisan, midab deggan.
