Muyezo wa kuuma kwa waya wachitsulo chamalangeti

Kuuma ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pamakina azinthu zachitsulo.Thewaya wachitsulofakitale imayambitsa njira yoyesera yofulumira komanso yotsika mtengo yoyesa kuuma.Komabe, pakuuma kwazinthu zachitsulo, palibe tanthauzo logwirizana komanso lomveka bwino kuphatikiza njira zonse zoyesera kunyumba ndi kunja.Kawirikawiri, kuuma kwachitsulo nthawi zambiri kumaonedwa kuti ndi kukana kwa zinthu za pulasitiki, zokopa, kuvala, kapena kudula.

Coil wamkuluwaya wamalatamu nthaka kumiza mtunda debugging, kusunga liwiro choyambirira osasintha, malinga t = KD kudziwa nthaka kumiza nthawi (1), pamene: T ndi nthaka kumizidwa nthawi zonse, kutenga 4-7D ndi awiri a zitsulo waya mm , ndiyeno yerekezerani mtunda womizidwa ndi zinki.Posintha mtunda wa zinc dip, nthawi ya zinc dip ya waya wachitsulo wamitundu yosiyanasiyana imatha kufupikitsidwa ndi 5s pafupifupi.Mwanjira imeneyi, kugwiritsa ntchito zinki pa tani imodzi ya waya wachitsulo kumachepa kuchokera pa 61kg mpaka 59.4kg.

Hot kuviika galvanizing ndi otentha Sungunulani zinki madzi kuviika plating, kupanga liwiro, wandiweyani koma wosafanana ❖ kuyanika, msika amalola makulidwe a microns 45, mpaka 300 microns pamwamba.Ndi mtundu wakuda, umadya zitsulo zambiri za zinki, umapanga wosanjikiza wolowera ndi chitsulo choyambira, ndipo umalimbana bwino ndi dzimbiri.Kutentha kwa dip galvanizing kumatha kusungidwa kwazaka zambiri m'malo akunja.Kutetezedwa kwa kupaka zinki pazitsulo zachitsulo kumakhala ndi mfundo ziwiri: kumbali imodzi, ngakhale nthaka imakhala yogwira ntchito komanso yosavuta kutulutsa oxidize kuposa chitsulo, koma filimu yake ya oxide si yotayirira komanso yophatikizika ngati iron oxide.Kuchuluka kwa okusayidi wosanjikiza komwe kumapangidwa pamwamba kumalepheretsa kuwonjezereka kwa zinki mkati.

Makamaka pambuyo passivation wamalatawosanjikiza, pamwamba pa oxide wosanjikiza ndi thicker ndi yaying'ono, palokha ali mkulu makutidwe ndi okosijeni kukana.Komano, pamene pamwamba pa kanasonkhezereka wosanjikiza kuonongeka, kuvumbulutsa mkati chitsulo masanjidwewo, chifukwa nthaka yogwira kuposa chitsulo, nthaka adzakhala ndi udindo wa nsembe zinki anode, nthaka adzakhala oxidized pamaso chitsulo, kuti atetezedwe. chitsulo chosanjikiza sichidzawonongeka.
