ʻO ka hoʻoheheʻe ʻia ʻana o ka coil Galvanized

ʻO ka wehewehe pōkole:

ʻO ka Galvanizing e pili ana i ka ʻenehana lapaʻau ʻili o ka uhi ʻana i kahi papa o ka zinc ma luna o ka ʻili o ka metala, alloy a i ʻole nā ​​​​mea ʻē aʻe no ka nani a me ka pale ʻana i ka ʻōpala.ʻO ke ala nui ka galvanizing wela.

Hiki ke hoʻoheheʻe ʻia ka Zinc i ka waikawa a me ka alkali, no laila ua kapa ʻia ʻo ia me ka metala amphoteric.ʻAʻole loli ka Zinc i ka ea maloʻo.Ma ka ea haʻahaʻa, e hana ʻia kahi kiʻiʻoniʻoni zinc carbonate kumu ma ka ʻili zinc.I loko o ka lewa i loaʻa ka sulfur dioxide, hydrogen sulfide a me ka lewa moana, maikaʻi ʻole ka pale ʻana o ka zinc, ʻoi aku ka maikaʻi o ka lewa i loko o ka waika organik i ke kiʻekiʻe o ka mahana a me ka haʻahaʻa, ua maʻalahi ka hoʻopili ʻia o ka zinc.ʻO ka mana electrode maʻamau o ka zinc he -0.76v.No ke kila kila, pili ka zinc coating i ka anodic coating.Hoʻohana nui ʻia e pale i ka corrosion o ke kila.ʻO kāna hana pale e pili pono ana i ka mānoanoa o ka uhi.Hiki ke hoʻomaikaʻi maikaʻi ʻia nā mea pale a me nā mea hoʻonaninani o ka zinc coating ma hope o ka passivation, dyeing a i ʻole ka uhi ʻana me ka mea pale māmā.
