Njira yothandizira pamwamba ndi ndondomeko ya chubu yamkuwa yamkuwa

1. Pentanimkuwa
Ntchitoyi ndi yochotsa ntchito zakumbuyo, zomwe sizimagwiritsidwa ntchito kawirikawiri. Njira: Mabasi oyendera magawo atatu a AC azipakidwa utoto wakuda, ndipo khodi yamtundu idzayikidwa m'malo owoneka bwino. Gawo A lidzakhala lachikasu, gawo B lidzakhala lobiriwira, ndipo gawo C lidzakhala lofiira. Mzere wosalowerera ndale kapena mzere wosalowerera upake utoto wabuluu wopepuka.
2. Kupaka malata pazitsulo zamkuwa
Ubwino: okhwima ndondomeko. Nthawi yayitali yogwira ntchito, yomwe imagwiritsidwa ntchito kwambiri. Kufooka: nthawi yaitali pamwamba tsitsi mdima, manja sangathe kuchita. Osati kuteteza chilengedwe!
Kutuluka kwa ndondomeko: kupukuta pamwamba, kuchotsa mafuta ndi kudzoza kwina → kutsuka madzi oyera → plating mkulu wa Pb-Sn aloyi kutsuka madzi apampopi → kuchapa madzi oyera → plating → kuchapa madzi apampopi → neutralization (Na2HPO4+Na3PO4)→ kuchapa madzi opopera → kuviika madzi a stearic acid → kuchapa madzi owuma → kuchapa → kuchapa madzi owuma → kuchapa madzi ofunda
3. Mkuwa wamkuwa wokutidwa ndi woteteza
Ubwino: kukhalabe ndi mtundu woyamba wa mkuwa, wotsika pang'ono kuposa mtengo wa malata. Zoipa: Kugwira ntchito kwautali.
Kutuluka kwa njira: kupukuta musanayambe mankhwala → kuchapa madzi oyera → pickling passivation workpiece → kuyanika chinyezi →JLR-510 chithandizo chachitetezo → kuyeretsa madzi oyenda → kumiza m'madzi otentha (pafupifupi 100 ℃, kugwiritsidwa ntchito potenthetsa workpiece, cholinga cha madzi evaporation kapena kuyanika) → kuyanika → phukusi kutsekedwa.
Chitoliro chamkuwa chodziwikiratu ndi mzere wopukutira chimadziwika chifukwa chimakhala ndi chipangizo chokhotakhota, chida chothandizira, chipangizo choyeretsera, chipangizo choyezera komanso cholumikizira chomwe chimayikidwa motsatira njira yoyenda ya chitoliro chamkuwa podutsa ndikupumula. Mmenemo, chipangizo chotsegulira, chotsegula chipangizo cha chubu chamkuwa chotsegula; Chipangizo chothandizira chubu cha Copper, chipangizo chothandizira chimagwiritsidwa ntchito pothandizira chipangizo chotsitsimula pambuyo pa chubu chamkuwa chotsegula;
