Ua kapa ʻia ʻo Hot dip galvanizing o ka pā kila.Hoʻoheheʻe ʻia nā ingots Zinc i loko o nā ʻāina ākea a ua hoʻohui ʻia kekahi mau mea kōkua i ka galvanizing wela.Hoʻopiliʻia nā'āpana kila kila i loko o ka pahu galvanizing a hoʻopaʻaʻia kahi papa galvanizing i ka pā kila.ʻO ka ikaika o ka galvanizing wela e pili ana i kona pale ʻana i ka corrosion, a ʻoi aku ka maikaʻi o ka adhesion a me ka paʻakikī o ka pepa galvanized.ʻO ka nui o ka pā kila galvanized ma hope o ka galvanizing.No laila ʻo kēia ka nui o ka zinc.
ʻO ka hoʻohui ʻana o ka papa galvanizing wela wela ka papa galvanizing wela, kahi i haku ʻia me ka hao zinc alloy ma waena o ka hao matrix a me ka papa zinc maʻemaʻe.Hoʻokumu ʻia ke ʻano o ka mea hana e ka ʻāpana hao zinc alloy i loko o ka wela wela, i mea e hoʻopā ai ka hao a me ka papa zinc maʻemaʻe.Ke hoʻokomo ʻia ka mea hana hao i loko o kahi solution zinc hoʻoheheʻe ʻia, hoʻokumu ʻia ka zinc mua a me ka hao (kino) ma ke kikowaena.He aniani kēia i hana ʻia me nā ʻātoma zinc i loko o ka hao metala paʻa.Ke hui pū ʻia nā ʻātoma metala ʻelua, liʻiliʻi loa ka ikaika umekaumaha ma waena o nā ʻātoma.
No laila, i ka lawa ʻana o ka zinc i loko o kahi heheʻe paʻa, hoʻopuehu nā ʻātoma ʻelua o ka zinc a me ka hao kekahi i kekahi.Hoʻoneʻe ʻia nā ʻātoma zinc i loko o ka lattice o ka matrix, a ua hoʻokumu ʻia nā mea hao i loko o nā ʻāpana.Hiki ke hoʻohana ʻia ke ʻano zinc o ka hao a me ka hui intermetallic FeZn13 i loko o ka hoʻoheheʻe zinc hoʻoheheʻe ʻia a me ka lalo o ka pepa galvanized wela e like me ka zinc slag.ʻO ka papa zinc maʻemaʻe i haku ʻia me ka hoʻoheheʻe leaching zinc he aniani hexagonal.
Ke holo ka mahana i ka mahana like a mālama ʻia ka wela like, ʻaʻole like ka nui o ka hao i hoʻoheheʻe ʻia.Ma kahi o 500, piʻi nui ka poho o ka hao me ka hoʻohui ʻana o ka mahana a me ka insulation.He haʻahaʻa a ʻoi aku paha ma mua o 480 ~ 510c, a ʻoi aku ka lohi o ka nalowale o ka hao epitaxial, a paʻakikī ke hopu i ka lōʻihi.No laila, e kāhea nā mea a pau i ka 480 ~ 510c ka wahi hoʻoheheʻe malignant.
I loko o kēia pae wela, ua ʻino loa ka hopena zinc i ka mea hana a me ka ipu hao, a nalowale ka hao ma 560 degere Celsius e hoʻohui maopopo, a ʻo ka zinc ka mea hao ma luna o 660 degere Celsius, e hoʻohui ʻia ka zinc slag. wikiwiki, ʻaʻole hiki ke hoʻohana i ka plating.No laila, lawe ʻia ka electroplating ma ka laulā o 430 ~ 450 degere Celsius.
