Piʻi ʻana:
E like me ka hoʻopaʻa ʻana, ka mahana a me ka wikiwiki, hoʻohana ʻia nā ʻakika e wehe i ka ʻili iron oxide ma ke ʻano kemika, i kapa ʻia ʻo pickling.
Phosphating:
ʻO ke kaʻina hana o ka hana ʻana i ka uhi phosphate ma ka ʻili metala ma o nā hopena kemika a me ka electrochemical.Ua kapa ʻia ke kiʻi hoʻololi phosphate i hana ʻia he kiʻiʻoniʻoni phosphating.
Ke kumu: E hoʻonui i ka anti-corrosion a me nā waiwai anti-rust o ka ʻili o ka mea.I ka manawa like, ʻo ke kiʻi phosphate i hana ʻia ma ke ʻano he lubricating carrier he hopena maikaʻi me ka lubricant a hoʻemi i ka coefficient friction surface o ka hoʻoili ʻana o ka mea.E hoʻomaikaʻi i ka hoʻopili pena a hoʻomākaukau no ka hana aʻe.
Saponification:
Ma hope o ka phosphating ka workpiece, ka stearate a me ka zinc phosphate kiʻiʻoniʻoni i loko o ka hopena i hoʻokomo ʻia i ka ʻauʻau saponification e hana i kahi papa saponification zinc stearate.Ke kumu: E hana i kahi papa saponification me ka adsorption maikaʻi loa a me ka lubricity ma luna o ka ʻili o ka mea, i mea e hoʻomaʻamaʻa ai i ka holomua o ka ʻenehana hana hope.
ʻO ke ʻano o ka pickling rust a me ka unahi ka mea i hoʻohana nui ʻia ma ke kahua ʻoihana.Hoʻokō ʻia ke kumu o ka wehe ʻana i ka ʻōpala a me ka paona oxide e ka hopena mechanical stripping o ka waika ma luna o ka oxide dissolution a me ka corrosion e hana i ke kinoea hydrogen.ʻO nā mea maʻamau i hoʻohana ʻia i ka pickling he hydrochloric acid, sulfuric acid, a me ka phosphoric acid.ʻAʻole hoʻohana ʻia ka ʻakika Nitric no ka mea e hoʻopuka ana i ke kinoea nitrogen dioxide ʻona i ka wā pickling.Hiki ke hoʻohana ʻia ka waiʻona hydrochloric pickling no ka hoʻohana ʻana i nā haʻahaʻa haʻahaʻa, ʻaʻole pono e ʻoi aku ma mua o 45 ℃, pono e hoʻohui pū i ka nui kūpono o ka waika noe inhibitor.ʻO ka wikiwiki o ka pickling o ka sulfuric acid ma ka haʻahaʻa haʻahaʻa he lohi loa, kūpono ia e hoʻohana i ka mahana wela, ka mahana 50 - 80 ℃, hoʻohana i ka ʻike o 10% - 25%.ʻO ka maikaʻi o ka phosphoric acid pickling ʻaʻole ia e hoʻohua i nā koena corrosive, ʻoi aku ka palekana, akā ʻoi aku ka maikaʻi o ka phosphoric acid, ʻoi aku ka nui o ke kumukūʻai, ʻoi aku ka wikiwiki o ka pickling wikiwiki, ʻo ka hoʻohana maʻamau ʻo 10% a 40%, a hiki ke hoʻololi ʻia ka mahana hana. ka mahana maʻamau i 80 ℃.I ke kaʻina hana pickling, ʻo ka hoʻohana ʻana i nā ʻakika hui ʻia he ala maikaʻi loa ia, e like me ka waikawa hydrochloric-sulfuric acid i hui pū ʻia, phosphoric acid-citric acid i hui pū ʻia.
Hoʻopili piha ʻia ka laina pickling i hoʻolālā ʻia e Wuxi T-control.Hana ʻia ke kaʻina hana i loko o kahi pahu paʻa a hoʻokaʻawale ʻia mai ka honua waho;lawe ʻia ka noe waika e ka hale kiaʻi noe no ka hoʻomaʻemaʻe ʻana;hoʻokaʻawale ʻia ke kaʻina hana mai ke olakino o ka mea hana Impact;ka mana otometi, ka hana kiʻekiʻe o ka hana, ka puka nui, ka mea kūpono no ka hoʻopuka nui, ka hana kikowaena;kamepiula 'akomi mana o ke kaʻina kaʻina hana, paʻa kaʻina hana;i hoʻohālikelike ʻia me ka laina hana pickling phosphating ma mua, ua hoʻomaikaʻi maikaʻi ʻia ka hana, akā ʻoi loa ka hoʻemi ʻana o ka honua i ka pollution i ke kaiapuni.
