Chitoliro chozungulira chopangidwa ndi galvanizing

Mapaipi achitsulo opangidwa ndi galvanizing amagawidwa m'mitundu iwiri: galvanizing yotenthetsa ndi galvanizing yamagetsi. Gawo lotenthetsa ndi lolimba, mtengo wa galvanizing yamagetsi ndi wotsika, ndipo pamwamba pake sipamakhala posalala kwambiri. Chitoliro chofewa chofewa ndi okosijeni: chimagwiritsidwa ntchito popanga mapaipi ophera okosijeni, nthawi zambiri mapaipi achitsulo opangidwa ndi mainchesi ang'onoang'ono, okhala ndi ma specifications asanu ndi atatu kuyambira mainchesi 3/8 mpaka 2. Gwiritsani ntchito 8, 10, 15, 20 kapena Yapangidwa ndi chitsulo cha 195-Q235, kuti tipewe dzimbiri, ndikofunikira kuchita chithandizo cha aluminiyamu.

Chitoliro chopangidwa ndi galvanized chotenthedwa ndi hot-dip chimapangitsa chitsulo chosungunuka kugwirizana ndi matrix yachitsulo kuti chipange gawo la alloy, kotero kuti matrix ndi chophimbacho ziphatikizidwe. Kuthira galvanization ndi choyambira ndi kuthira chitsulo. Pofuna kuchotsa chitsulo chosakanizika pamwamba pa chitoliro chachitsulo, chikatha kuthira, chimatsukidwa mu thanki ndi ammonium chloride kapena zinc chloride kapena yankho lamadzimadzi losakanikirana la ammonium chloride ndi zinc chloride, kenako nkutumizidwa ku thanki yothira pulasitiki yotentha. Kuthira galvanization ndi hot-dip kuli ndi ubwino wa kuphimba kofanana, kumamatira mwamphamvu komanso kukhala ndi moyo wautali.

Kukonza ma galvanizing ozizira ndi electro-galvanizing, ndipo kuchuluka kwa ma galvanizing ndi kochepa kwambiri, 10-50g/m2 yokha, ndipo kukana kwake dzimbiri n'koipa kwambiri kuposa mapaipi opangidwa ndi ma galvanizing otentha.
