Electro galvanizing
Tsanangudzo Pfupi
Electro galvanizing: inozivikanwawo sekutonhora galvanizing muindasitiri, inzira yekugadzira yunifomu, dense uye yakanyatso sungirirwa simbi kana alloy deposition layer pamusoro peiyo workpiece ne electrolysis.
Kana ichienzaniswa nedzimwe simbi, zingi yakachipa uye iri nyore kuiswa.Iyo yakaderera kukosha anti-corrosion electroplated coating.Inoshandiswa zvakanyanya kuchengetedza simbi nesimbi, kunyanya kudzivirira kuparara kwemhepo, uye yekushongedza.Tekinoroji yeplating inosanganisira yekugezesa yekugezera (kana kuturika plating), mbiya plating (inokodzera zvikamu zvidiki), bhuruu plating, otomatiki plating uye inoenderera plating (yakakodzera waya uye tambo).

Chinangwa che electro galvanizing ndechekudzivirira zvinhu zvesimbi kubva pakusvibiswa, kuvandudza kusagadzikana kwekuora uye hupenyu hwebasa resimbi, uye kuwedzera kutaridzika kwekushongedza kwezvigadzirwa.Simbi ichasvibiswa nemamiriro ekunze, mvura kana ivhu nekuwedzera kwenguva.KuChina, simbi yakaora inotora chikamu chimwe mugumi chehuwandu hwesimbi gore rega rega.Nokudaro, kuitira kuchengetedza hupenyu hwebasa resimbi kana zvikamu zvayo, electro galvanizing inowanzo shandiswa kugadzira simbi.
Nekuti zingi haisi nyore kuchinja mumhepo yakaoma uye inogona kugadzira yakakosha zinc carbonate firimu munzvimbo ine hunyoro, iyi firimu inogona kudzivirira mukati kubva mukukuvadzwa kwecorrosion.Kunyange kana zinc layer yakakuvadzwa nezvimwe zvinhu, zinc nesimbi zvichabatana kuti zviumbe micro bhatiri mushure menguva yakati rebei, kuitira kuti matrix esimbi ive cathode uye inodzivirirwa.Zvinogumiswa kuti electro galvanizing ine zvinotevera maitiro:
Iyo ine yakanaka corrosion resistance, yakanaka uye yakafanana musanganiswa, uye haisi nyore kupinzwa ne gasi rinoparadza kana mvura.
Nekuda kwekuti zinc layer yakanyatso kuchena, hazvisi nyore kuti corroded mu acid kana alkali nharaunda.Kunyatso chengetedza muviri wesimbi kwenguva yakareba.
Inogona kushandiswa mumarudzi akasiyana-siyana mushure mechromate passivation.Inogona kusarudzwa maererano nezvinodiwa nevatengi.Galvanizing yakanaka uye inoshongedza.
Iyo zinc coating ine yakanaka ductility uye haizodonha nyore panguva dzakasiyana dzekukotama, kubata uye kukanganisa.
