ʻO ke kila hoʻoheheʻe wela wela

He ʻano mea maka i kapa ʻia (zinc, aluminika) i uhi ʻia ma ka pā kila lōʻihi a haiki o ka ʻōwili anu a i ʻole ka wela.Loaʻa i ka galvanizing wela nā mea maikaʻi o ka uhi ʻana i ka lole, ka adhesion ikaika a me ke ola lawelawe lōʻihi.ʻO ka hopena kino a me ke kemika paʻakikī ma waena o ke kāʻei hao hao wela a me ka hoʻoheheʻe hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao me ka hana paʻa.Hoʻohui pū ʻia ka ʻāpana alloy me ka papa zinc maʻemaʻe a me ka substrate kila.No laila, ikaika kona pale ʻana i ka corrosion.

1.ʻO ka galvanizing wela: ma hope o ka pickling, hoʻomaʻemaʻe ʻia e ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia me ka pahu wai wai.A laila hoʻouna ʻia i ka pahu galvanizing hot dip no ka galvanizing.

2.Hot galvanizing: ma hope o ka pickling, ua hoʻomaʻemaʻe ʻia i ka ʻauʻau o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia i ka wai, a laila hoʻouna ʻia i loko o ka ʻauʻau galvanizing ma hope o ka hoʻomau ʻana i ka umu annealing no ka galvanizing.

3.Direct galvanizing: ma hope o ka pickling, hoʻouna ʻia i loko o ka umu annealing mau a laila i loko o ka pahu galvanizing no ka galvanizing.
