China Paint Galvanized Zinc Sheet/Coil
Basic Concept:
Pamusoro pechikamu chinoramba chiripo, simbi inotonhora-yakaputirwa simbi uye galvanized strip simbi (electro-galvanized and hot-dip galvanized) inoshandiswa se substrates, uye mushure mekugadzirisa kwepamusoro (kuderedza uye kurapwa kwemakemikari), nzira yekuputira roller inoshandiswa.
Imwe kana mamwe zvidimbu zvependi yemvura inoshandiswa, uye pepa rinowanikwa nekubika uye kutonhora rinonzi simbi yakavharwa.
Sezvo kuvhara kunogona kuva nemhando dzakasiyana-siyana dzemavara, itsika yekuisa simbi yakavharwa.
Mahwendefa anonzi color coated steel plates. Uye nekuda kwekuti kupfekedzwa kunoitwa ndiro yesimbi isati yaumbwa, inonzi pre-coated steel plate kune dzimwe nyika.
Process flow:
Mashizha esimbi akavharwa nemavara akavakirwa pane simbi inotonhora-yakakungurutswa uye galvanized simbi. Mushure mekugadzirisa kwepamusoro (kuderedza, kuchenesa, kushandiswa kwemakemikari kutendeuka), machira anoshandiswa nenzira inopfuurira.(roller coating method), chigadzirwa chakagadzirwa nekubika uye kutonhora.
Iyo huru yekugadzira maitiro eyakajairwa maviri-kuputira uye maviri-aviri anoenderera eruvara coating unit process kuyerera ndeye: kusunungura → preatment → kupfekedza → kubheka → post-kugadzirisa → kukoira.

Application:
Coated simbi ndiro ine huremu huremu, chitarisiko chakanaka uye yakanaka corrosion kuramba, uye inogona kugadziriswa zvakananga.
Inopa rudzi rutsva rwezvinhu zvakasvibirira, zvine mhedzisiro yakanaka sekutsiva huni nesimbi, kuvaka kwakanaka,
kuchengetedza simba, uye kudzivirira kusvibiswa. Kuvhara kwemavara uchishandisa galvanized simbi sheet se substrate
Pamusoro pekudzivirira zinc, iyo organic coating pane zinc layer inoita basa rekuvhara uye kuzviparadzanisa nevamwe, izvo zvinogona.
kudzivirira ndiro yesimbi kubva kune ngura, uye hupenyu hwayo hwebasa hwakareba kupfuura iyo yeplate yesimbi.
Zvichienderana nenhanganyaya, hupenyu hweplate yakavharwa hurefu ne50% pane huya hwegalvanized steel plate.
