ʻO ka hoʻomalu maikaʻi ʻana o ka uhi uea galvanized ʻōwili nui

1. Hoʻoponopono i nā ʻāpana kaʻina hana electroplating

E mālama pono i ka waiwai pH o ka ʻōwili nuiuwea galvanizedʻauʻau, hōʻike noiʻi i ka nui o ka wai ʻauʻau pH pili pono i ka maikaʻi o ka uhi uea kila, ka mana kūpono ʻole o ka waiwai pH e hoʻokuʻu i ka uhi.Ke ʻoi aku ka nui o ka pH ma mua o 3, ʻo ka uhi uea kila he burr i hana ʻia e nā dendrites maikaʻi, a ʻaʻole maʻalahi ka ʻili.Hoʻomalu pono ʻia ka nui o kēia manawa.Mai ka microscopic morphology, ʻoi aku ka kiʻekiʻe o ka nui o kēia manawa, ʻoi aku ka nui o ka waiho ʻana o ka palaoa zinc layer, ʻoi aku ka liʻiliʻi o ka ʻāpana zinc pili.

ʻO ka mea ʻē aʻe, ʻoi aku ka nui o ka deposition ion, ʻoi aku ka maikaʻi o ka papa zinc.Ma lalo o ke ʻano he ʻeleʻele a ʻālohilohi ka papa zinc o ka honua, pono ka maikaʻi o ka papa zinc ma kēlā me kēia wahi i ka 80g/m2, a pono e hoʻonui ʻia nā ʻāpana kaʻina penei: ʻo 16-20A / dm2 ka nui o kēia manawa, ka nui o ka zinc. ʻO ka hopena sulfate he 500g/L, a ʻo ka waiwai pH he 2.5-3.0.

2. Hoʻoponopono i nā ʻāpana kaʻina hana kiʻi o ka pahu wai

E like me ka nui-pass liʻiliʻi compression rate kaha kiʻi, ʻo ka huina hoʻopiʻi helu he 96.48%, e hōʻemi ana i ka ʻoki ʻana o ka papa zinc.Hana ʻia ka make kiʻi uea holoʻokoʻa me ka tungsten steel make a me ka polycrystalline die.ʻO ka Angle o ka cone hana o ke kaha kiʻi uea make he 12 ° ~ 16 °, a ʻo ka lōʻihi o ke kāʻei sizing he 0.15 o ke anawaena o ka uea, i mea e hōʻoia ai i ka hoʻololi ʻana o ka papa zinc i ka like me ka. uea kila substrate.

Hoʻohana ka ʻōnaehana hoʻoluʻu e hoʻomaʻalili i ka make kiʻi kiʻi, a lawe aku i ka wela nui i hana ʻia e ka mīkini kaha kiʻi ma ke kaha kiʻi kiʻekiʻe i ka manawa e hōʻoia ai i ka maikaʻi o ka uea.Hoʻoholo i nā ʻāpana kaʻina hana kiʻi: kaha kaha kiʻi 10 ~ 12m/s;ʻO ka wili makani 8 ~ 10N;Ana ka loa 30km;ʻO ka hapa nui o ka lubricant he 3.5 ~ 4.5%;pH waiwai o ka lubricant 7 ~ 8;ʻO ka mahana wela 30 ~ 40 ℃.

Ma hope o ka optimization o ke kaʻina hana, hana nui o 0.80mm electrouwea hao haoHoʻomalu ʻia ka maikaʻi o ka papa zinc electro galvanized i loko o 80 ~ 90g/m2, liʻiliʻi loa ka hoʻopuehu ʻana o ka zinc layer quality;Hōʻike nā hopena i ka awelika kaumaha o ka papa zinc he 14.5g / m2, ʻo ka nalowale o ka papa zinc ma lalo o 5%, a ʻo ka ikaika tensile o ke kaula kila he 2300 ~ 2500MPa.ʻAʻole wale ia e hoʻomalu pono i ka maikaʻi o ka papa zinc o ka uea kila maka, akā e hōʻemi ana i ka ʻōpala pono ʻole a me ke kumukūʻai hana.
