Ukucutshungulwa ikhoyili ekhandiwe

Incazelo emfushane:

I-galvanizing ibhekisela kubuchwepheshe bokwelapha obungaphezulu bokunamathisela ungqimba lwezinc phezu kwensimbi, ingxubevange noma ezinye izinto zobuhle nokuvimbela ukugqwala.Indlela eyinhloko ukugalela amanzi ashisayo.

I-Zinc incibilika kalula ku-asidi ne-alkali, ngakho ibizwa nge-amphoteric metal.I-Zinc ayishintshi neze emoyeni owomile.Emoyeni onomswakama, ifilimu eyisisekelo ye-zinc carbonate izokwakhiwa endaweni ye-zinc.Emkhathini oqukethe i-sulfur dioxide, i-hydrogen sulfide nomkhathi wasolwandle, ukumelana nokugqwala kwe-zinc kubi, ikakhulukazi emkhathini oqukethe i-asidi ephilayo ekushiseni okuphezulu nomswakama, i-zinc enamathela kulula kakhulu ukugqwala.Amandla we-electrode ajwayelekile we-zinc ngu-0.76v.Nge-substrate yensimbi, i-zinc coating ingeye-anodic coating.Isetshenziselwa ikakhulukazi ukuvimbela ukugqwala kwensimbi.Ukusebenza kwayo okuyisivikelo kuhlobene eduze nogqinsi lokwemboza.Izakhiwo zokuvikela nezokuhlobisa ze-zinc coating zingathuthukiswa kakhulu ngemuva kokudlula, ukudaya noma ukumbozwa nge-ejenti yokuvikela ukukhanya.
