1. Pfungwa dzakasiyana
Kupisa-kunyudza simbi, kunozivikanwawo sekupisa-kunyudza simbi uye kupisa-kunyudza simbi, inzira inoshanda yekudzivirira ngura, inonyanya kushandiswa muzvivakwa zvesimbi mumaindasitiri akasiyana-siyana. Kunyudza zvikamu zvesimbi zvakabviswa ngura mumushonga wezinc wakanyungudutswa pa500°C, kuitira kuti pamusoro pezvikamu zvesimbi zvinamire kune zinc layer, kuitira kuti chinangwa chekudzivirira ngura chibudirire.
Kugadzira electrogalvanizing, inozivikanwawo se cold galvanizing muindasitiri, inzira yekushandisa electrolysis kugadzira simbi yakafanana, yakakora uye yakabatana zvakanaka kana alloy deposition layer pamusoro pebasa. Kana ichienzaniswa nedzimwe simbi, zinc isimbi yakachipa uye iri nyore kuputira. Inodzivirira ngura isingadhuri uye inoshandiswa zvakanyanya kudzivirira zvikamu zvesimbi, kunyanya kubva mukuora kwemhepo, uye pakushongedza.
2. Maitiro acho akasiyana
Kufamba kwemaitiro ekupisa-kunyika: kunyungudutsa zvigadzirwa zvakapedzwa - kuwacha - kuwedzera mvura yekuputira - kuomesa - kuputira parack - kutonhodza - kurapwa nemakemikari - kuchenesa - kukuya - kuputira-kunyika pakupisa kwapera.
Kuyerera kwemaitiro emagetsi: kubvisa mafuta emakemikari - kuwacha nemvura inopisa - kuwacha - kubvisa mafuta emagetsi - kuwacha nemvura inopisa - kuwacha - ngura yakasimba - kuwacha - alloy yesimbi yakasanganiswa nemagetsi - kuwacha - kuwacha - kupenya - kupfava - kuwacha - kuomesa.
3. Unyanzvi hwakasiyana
Kune nzira dzakawanda dzekugadzirisa galvanizing yekupisa. Kana chinhu chebasa chabviswa mafuta, kunyungudutswa, kunyikwa, kuomeswa, nezvimwewo, chinogona kunyikwa mubhavhu rezinc rakanyungudutswa. Sezvimwe zvinhu zvinopinzwa mupombi dzinopisa zvinogadziriswa nenzira iyi.
Kugadzika kwemagetsi kunogadziriswa nemidziyo yemagetsi. Mushure mekudzima mafuta, kukwesha uye mamwe maitiro, kunonyudzwa mumushonga une zinc salt, uye michina yemagetsi inosanganiswa. Munguva yekufamba kwemhepo dzakanaka nedzisina kunaka, zinc layer inoiswa pachinhu chebasa.
4. Chitarisiko chakasiyana
Kuonekwa kwese kwe hot-dip galvanizing kwakaomarara zvishoma, izvo zvinogadzira mitsetse yemvura inoyerera, mabundu anodonhedza mvura, nezvimwewo, kunyanya pamucheto we workpiece, iyo ine sirivha chena yese. Rutivi rwepamusoro rwe electro-galvanizing rwakatsetseka, kunyanya yero-girini, hongu, kunewo mavara, bhuruu-chena, chena nechiedza chegirini, nezvimwewo. Workpiece yese haina kuoneka zinc nodules, agglomeration nezvimwe zviitiko.
