Chii coating anogona kuita kupedza jasi ruvara besmear bhodhi rinoshandiswa pashure nguva, nokuti kukanganiswa nemarudzi ose ezvinhu kwezvakatipoteredza, ayo besmear firimu pfuma uye basa upenyu zvinogona kuderedza, vanofanira kuita repaint kune yayo.Izvo zvinonyanya kudikanwa zvekupfekedzwa kwependi kuve nekumwe dhigirii rekunamatira neiyo yekutanga coating, uye kusimba kuri nani.Kunze kweruvara rakaputirwa bhodhi zvinoenderana nekushandiswa kwezvakatipoteredza rinogona kukamurwa kuita zvikamu zvitatu, chikamu chekutanga, kushandiswa munzvimbo yechisikigo, zvinodiwa zveimwe anti-corrosion athari.Zvakadai se: nzvimbo yekuvaka, uchishandisa ruvara coated board kuparadzaniswa;Kirasi 2, inoshandiswa mumamiriro echisikigo, ine imwe nzira yekudzivirira kuora uye maitiro ekuonekwa.Sezvo: mukugadzirwa kwekunze kweimba yebhodhi;Chikamu chechitatu, chinoshandiswa mune dzimwe nzvimbo dzakaoma, chinoda imwe nhamba yehupenyu hunopesana nekuora.
Simba rekunamira pane akasiyana mavara akavharwa mahwendefa kuti aone iyo yekubikira system yemavara akavharwa mahwendefa.Polyester amino system coating surface ine huwandu hukuru hwe hydroxyl uye amino mapoka, uye chivakwa cheruvara rwekuputira ndiro kazhinji semi-optical coating, coating ine huwandu hukuru hwemafirita kana matting poda, iyo micro surface inopa humwe hukasha, nyore uye kugadzirisa. kukoira paboka rehydrogen bonding uye doxtail wedge effect, saka kunamatira kwakasimba.
Zvinoenderana neiyo yepamusoro wetting theory, kushushikana kwepamusoro kweiyo yakasarudzwa kugadzirisa coating kunofanirwa kunge kwakadzikira pane tension yepasi pevara topcoat yekunyorova;Kugadzirisa zvipfeko kunofanira kunge kune mapoka epolar anogona kuumba hydrogen bonds;Gadzirisa pendi kuti ive yakasimba solvent inogona kuzvimba pendi, kuitira kuvandudza adhesion pakati akaturikidzana;Panguva imwecheteyo, iyo yekupfekedza inogona kushandiswa kudzikisa huremu hwema molecular resin kana kuderedza viscosity yejasi, kushandiswa kweanononoka kunyungudika solvent uye yakaderera-yekubatanidza chiyero chejasi kuvandudza kunamatira kwayo pane iyo ruvara rukukwe. ndiro.
