Substrate : Substrate-yada loogu talagalay gariiradaha birta ee midabaysan ee marmar-qaabaysan sida caadiga ah waxaa ka mid ah go'yaal qabow-duuban, xaashiyo bir ah oo kulul, ama go'yaal bir ah oo dahaaran Al-Zn. Waraaqaha birta ah ee qabow-duuban waxaa lagu gartaa tayada dusha sare iyo saxnaanta cabbirka sare, halka galvanized-kuleelka iyo alwaaxyada dahaarka leh ee Al-Zn ay bixiyaan iska caabin daxaleed oo heer sare ah, iyagoo siinaya ilaalin la xoojiyay iyo nolol adeeg dheer oo ku habboon jawiga hawlgalka ee kala duwan. Rinjiga: Dahaarka sida caadiga ah loo isticmaalo waxaa ka mid ah polyester-ka, polyester-ka silikoon-la beddelay, polyester-ka cimri-dheeraada, iyo fluorocarbon. Dahaarka polyester-ka waxay bixiyaan tayada qurxinta wanaagsan iyo socodsiinta qiimo jaban; Dahaarka polyester-ka silikoon-ku-beddelay waxay bixiyaan cimilo wanaagsan iyo caabbinta wasakhda; Dahaarka polyester-ka ee adkeysiga sare leh waxay bixiyaan iska caabin heer sare ah oo loogu talagalay walxaha dabiiciga ah sida shucaaca UV, dabaysha, iyo roobka; iyo dahaarka fluorocarbon waxay keenaan jawi aan caadi ahayn, iska caabin daxalka, iyo guryaha is-nadiifinta-ilaalinta midabada firfircoon iyo muuqaal soo jiidasho leh mustaqbalka fog-in kasta oo ay ku yimaadaan qiime sare.
