ʻO ka mānoanoa o ka wela-dip galvanized layer nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika, ke ola lōʻihi a me nā mea ʻē aʻe.He haʻahaʻa ke kumukūʻai o ka galvanizing, ʻaʻole maʻalahi ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka paipu galvanized wela.ʻO ke kaʻina hana o ka wela-dip galvanizing layer ke kaʻina hana o ka hana ʻana i ka hao zinc alloy ma waena o ka matrix hao a me ka papa zinc maʻemaʻe ma waho.Hoʻokumu ʻia ka ʻāpana hao zinc alloy ma luna o ka ʻili o ka mea hana i ka wā wela-dip galvanizing, kahi e hui maikaʻi ai ma waena o ka hao a me ka papa zinc maʻemaʻe.Hiki ke wehewehe wale ʻia ke kaʻina hana: i ka wā i hoʻokomo ʻia ai ka mea hana hao i loko o ka zinc hehee, ʻo ia ka zinc slag.Ke hoʻoneʻe ʻia ka mea hana mai ka solution immersion zinc, hoʻokumu ʻia kahi papa zinc maʻemaʻe ma luna o ka ʻili, ʻo ia ke aniani hexagonal.ʻAʻole ʻoi aku ka nui o ka hao ma mua o 0.003%.
ʻO ka paipu galvanized wela:
ʻO ia ka hana ʻana o ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana i kahi ʻāpana paʻa, i hui pū ai ka matrix a me ka uhi.Hot dip galvanizing mea e pickle mua ka paipu kila.I mea e wehe ai i ka hao oxide ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, ua hoʻomaʻemaʻe ʻia i loko 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 pahu wai wai, a laila hoʻouna ʻia i ka pahu galvanizing wai wela.Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.ʻO ka hapa nui o nā kaʻina hana ma ka ʻĀkau e hoʻohana i ke kaʻina o ka ʻōwili pololei ʻana i ke kaula hao e hoʻohui i ka zinc.ʻO ka matrix paipu kila a me ka hoʻoheheʻe hoʻoheheʻe hoʻoheheʻe he paʻakikī ko ke kino a me ke kemika, e hana ana i kahi papa hoʻoheheʻe zinc hao me ka paʻa paʻa.Hoʻohuiʻia ka papa'āpana me ka'āpana zinc maʻemaʻe a me ka matrix paipu kila.No laila, he ikaika ka corrosion kū'ē.
