Hoʻohana huahana

Loaʻa iā ia nā noi i nā ʻoihana electroplating a me electrolysis, a hiki ke hoʻohana ʻia hoʻi e hana i nā kaula.

Hoʻohana ākea ʻo Zinc sulfate heptahydrate i nā hāʻina galvanizing. I ka wā electroplating, ʻo ka pono nui loa o ka zinc sulfate heptahydrate solution galvanizing ʻo ia ka kiʻekiʻe o kēia manawa e like me 100% a wikiwiki ka helu o ka waiho. Kūlike ʻole kēia e nā hana galvanizing ʻē aʻe.

ʻO ke kaʻina hana kuʻuna sulphate zinc plating kūpono wale ia no ka electroplating o nā paipu a me nā kaula me nā ʻano geometric maʻalahi ma muli o ka nele o ka crystallization maikaʻi o ka uhi a me ka hiki ʻole o ka dispersion a me ka hiki ke hele i loko. I ke kaʻina electroplating zinc sulfate o ke kinikini hao, koe wale no ka paʻakai kiniki paʻakai, hoʻolei ʻia nā mea hana ʻē aʻe. Hoʻohui ʻia kahi nui kūpono o ka paʻakai hao i ka hana hana hou e hana i ka uhi pale hao hoʻokahi kumu i uhi uhi kiniki-hao. ʻO ka hoʻonohonoho hou ʻana o ke kaʻina hana ʻaʻole i lawe wale i mua nā mea maikaʻi o ke kūlana kiʻekiʻe o kēia manawa a me ka helu waiho wikiwiki o ke kaʻina hana mua, akā hoʻomaikaʻi maikaʻi hoʻi i ka hiki i ka hoʻopuehu a me ka hiki i ka plating hohonu. I ka wā ma mua, ʻaʻole hiki ke hoʻopili ʻia i nā ʻāpana paʻakikī, akā i kēia manawa hiki ke hoʻopili ʻia i nā ʻāpana maʻalahi a paʻakikī hoʻi, a me ka hana pale He 3 a 5 mau manawa ke kiʻekiʻe aʻe ma mua o ka metala hoʻokahi.

Ua hōʻoia ka hana ʻana i ka electrogalvanization mau o nā kaula a me nā paipu me ka zinc sulfate bath e ʻoi aku ka maikaʻi, ʻoi aku ka māmā a me ka wikiwiki o ka waiho ʻana ma mua o ka uhi mua. Kū i ke koi o ka uhi ʻana mānoanoa ma waena o 2 ~ 3min
