ʻO Zinc kahi kaʻina hana hoʻoheheʻe metallurgical.Mai ka hiʻohiʻona microscopic, ʻo ke kaʻina hana o ka hot dip galvanizing he ʻelua koena ikaika, ke kaulike wela a me ke kaulike hao hao zinc.Ke hoʻokomo ʻia ka mea hana kila ma kahi o 450℃ʻO ka wai zinc hoʻoheheʻe ʻia, ka wela wela o ka wai zinc absorption wela o ka mea hana, hiki i luna o 200℃, ua akaka ka pilina o ka zinc a me ka hao, zinc, hao ke komo i ka ʻili.Ke hoʻokokoke mālie nei ka mahana o ka mea hana i ka wela o ka zinc i hoʻoheheʻe ʻia, hana ʻia ka ʻili o ka mea hana me ka ʻokoʻa like ʻole o ka ʻāpana hao hao zinc, kahi hierarchical o ka zinc coating, me ka manawa lōʻihi, ʻo ka ulu ʻana o nā ʻāpana hoʻoheheʻe ʻokoʻa e hōʻike ana i ka wikiwiki wikiwiki.Mai kahi hiʻohiʻona macro, ʻo ka hana o ke kaʻina hana ma luna i hoʻokomo ʻia i loko o ka zinc wai, ʻo ka paila wai zinc i ka wā i hoʻohālikelike ʻia ka zinc, ka hopena hao, a mālie mālie ka ʻili zinc.Hana ʻia ka mea hanaʻo ka ʻili o ka zinc, e hoʻemi mālie ʻia ka mahana o ka mea hana ma lalo o 200℃, ua hookiia ka pane e ka zinc, hao, wela wela ka uhi galvanized ua hoʻoholo 'ia ka mānoanoa.

ʻO ka mānoanoa o ka zinc coating nā mea nui: kahi mea metala kumu, ka ʻili o ke kila, ke kila o nā mea hana silika a me ka phosphorus a me ka hāʻawi ʻana, ke koʻikoʻi o loko o ke kila, ka geometry mea hana, ke kaʻina hana galvanizing wela. .Hoʻokaʻawale ʻia nā kūlana o ka honua a me Kina i nā ʻāpana e like me ka mānoanoa kila, ka mānoanoa o ka mānoanoa o ka zinc coating a me ka huki ʻana i ke kūloko e hiki i ka mānoanoa kūpono, e hoʻoholo ai i ka hana anticorrosion zinc coating.ʻOkoʻa kila mānoanoa o ka workpiece, e hoʻokō thermal equilibrium, a me ka zinc ion hoʻololi equilibration i nā manawa like ʻole, ʻokoʻa ka mānoanoa o ka uhi ʻana.Hoʻokumu ʻia ka mānoanoa awelika o ka maʻamau coating ma ke ʻano o ka ʻike galvanizing i ka hana ʻenehana, ʻike ʻia ka mānoanoa kūloko o ka mānoanoa o ka zinc coating i ka mahele like ʻole o ka uhi a me nā koi pale corrosion e pono ai ka ʻike.No laila, ʻokoʻa iki nā kūlana ISO, nā kūlana ASTM, nā kūlana JIS a me nā kūlana Kina.

ʻO ka mānoanoa o ka zinc coating e hoʻoholo i ka hana o nā ʻāpana pale anticorrosion.No ka 3 mm ma lalo o ka ʻili o ka pā kila lahilahi, he paʻakikī ke kiʻi i kahi uhi ʻoi aku ka mānoanoa o ka hana ʻoihana, ʻoi aku, ʻaʻole i kūlike me ka mānoanoa o ka mānoanoa o ka zinc plating mānoanoa a e hoʻopilikia i ka ikaika adhesion o ka uhi a ka substrate a me ka maikaʻi o ka hiʻohiʻona.ʻO ka uhi mānoanoa ke kumu o ka uhi ʻana i ke ʻano o ka ʻili, maʻalahi ka peeling, ʻaʻole hiki i nā ʻāpana plating ke kū i ka hui ʻana i ke kaʻina hana a me ka hoʻonohonoho ʻana.Inā ʻoi aku ka nui o nā mea kila o ke silikoni a me ka phosphorus, ʻoi aku ka paʻakikī o ka hana ʻana i ka ʻoihana ʻoi aku ka paʻakikī, ʻo ia ka ʻike silika o ke kila i ka hopena ma waena o ke ʻano ulu ulu o ka zinc-hao.
