Umehluko phakathi kwe-electro galvanizing kanye ne-hot galvanizing

1. Imiqondo ehlukene

I-hot-dip galvanizing, eyaziwa nangokuthi i-hot-dip galvanizing kanye ne-hot-dip galvanizing, iyindlela ephumelelayo yokunqanda ukugqwala kwensimbi, esetshenziswa kakhulu ezindaweni zesakhiwo sensimbi ezimbonini ezihlukahlukene. Kuwukucwilisa izingxenye zensimbi ezikhishwe ukugqwala esixazululweni se-zinc esincibilikisiwe esingaba ngu-500 ° C, ukuze ubuso bezingxenye zensimbi bunamathele kungqimba lwe-zinc, ukuze kufezwe injongo yokulwa nokugqwala.

I-Electrogalvanizing, eyaziwa nangokuthi i-galvanizing ebandayo embonini, inqubo yokusebenzisa i-electrolysis ukwakha iyunifomu, insimbi ecinene futhi eboshwe kahle noma isendlalelo se-alloy deposition ebusweni bomsebenzi. Uma kuqhathaniswa nezinye izinsimbi, i-zinc iyinsimbi eshibhile futhi ecwecwe kalula. Kuyi-coat elwa nokugqwala enenani eliphansi futhi isetshenziswa kakhulu ukuvikela izingxenye zensimbi, ikakhulukazi ekugqwaleni komkhathi, kanye nokuhlobisa.

2. Inqubo ihlukile  

Ukugeleza kwenqubo ye-hot-dip galvanizing: ukukha imikhiqizo eqediwe - ukuwasha - ukwengeza isixazululo se-plating - ukomisa - ukufakwa kwama-rack - ukupholisa - ukwelashwa ngamakhemikhali - ukuhlanza - ukugaya - ukugalela okushisayo kwediphu kuqediwe.

Ukugeleza kwenqubo ye-Electrogalvanizing: ukukhishwa kwamakhemikhali - ukugeza kwamanzi ashisayo - ukugeza - ukukhishwa kwe-electrolytic - ukugeza kwamanzi ashisayo - ukugeza - ukugqwala okunamandla - ukugeza - i-electrogalvanized iron alloy - ukugeza - ukugeza - ukukhanya - passivation - ukugeza - ukomisa.

3. Ubuciko obuhlukene

Maningi amasu okucubungula ama-hot-dip galvanizing. Ngemuva kokuthi i-workpiece iyancipha, i-pickling, i-dipping, i-drying, njll., ingacwiliswa ekugezeni kwe-zinc encibilikisiwe. Njengamanye amapayipi okufaka amapayipi ashisayo acutshungulwa ngale ndlela.

I-Electrolytic galvanizing icutshungulwa ngemishini ye-electrolytic. Ngemuva kokunciphisa, ukuqoqa nezinye izinqubo, kucwiliswa esixazululweni esiqukethe usawoti we-zinc, futhi imishini ye-electrolytic ixhunyiwe. Ngesikhathi sokunyakaza okuqondiswayo kwemisinga emihle nemibi, ungqimba lwe-zinc lufakwa ku-workpiece. .

4. Ukubukeka okuhlukile

Ukubonakala sekukonke kwe-hot-dip galvanizing kubi kancane, okuzokhiqiza imigqa yamanzi enqubo, amathumba aconsayo, njll., ikakhulukazi ekugcineni kwendawo yokusebenza, emhlophe esiliva iyonke. Ungqimba olungaphezulu lwe-electro-galvanizing lubushelelezi, ikakhulukazi oluphuzi-luhlaza, yiqiniso, kukhona okumibalabala, okuluhlaza okwesibhakabhaka-mhlophe, okumhlophe ngokukhanya okuluhlaza okotshani, njll. I-workpiece yonke ngokuyisisekelo ayiveli amaqhuqhuva e-zinc, i-agglomeration nezinye izenzakalo.
