Ⅰ- ʻakikaPickling
1.-Wehewehe oAakika-Pickling: Hoʻohana ʻia nā ʻakika e hoʻoneʻe i ka unahi hao oxide ma ke ʻano kemika ma kekahi ʻano ʻano, wela, a me ka wikiwiki, ʻo ia ka mea i kapa ʻia ʻo pickling.
2.- ʻakika-Hoʻokaʻawale ʻana: E like me ke ʻano o ka waikawa, ua māhele ʻia i loko o ka sulfuric acid pickling, hydrochloric acid pickling, nitric acid pickling, a me ka hydrofluoric acid pickling.Pono e koho ʻia nā ʻano media like ʻole no ka pickling ma muli o nā mea o ke kila, e like me ka pickling carbon steel me ka sulfuric acid a me ka hydrochloric acid, a i ʻole pickling stainless steel me ka hui ʻana o ka waikawa nitric a me ka waikawa hydrofluoric.
E like me ke ʻano o ke kila, ua māhele ʻia i ka pickling wire, forging pickling, steel plate pickling, strip pickling, etc.
E like me ke ʻano o nā lako pickling, ua māhele ʻia i loko o ka pahu pickling, semi-continuous pickling, piha hoʻomau pickling, a me ka hale kiaʻi pickling.
3.- ʻO ke kumu o ka pickling acid: ʻO ka pickling acid ke kaʻina o ka wehe ʻana i nā unahi hao oxide mai nā ʻili metala me ka hoʻohana ʻana i nā ʻano kemika, no laila ua kapa ʻia ʻo ia ka pickling acid chemical.ʻO nā unahi hao oxide (Fe203, Fe304, Fe0) i hana ʻia ma luna o ka ʻili o nā paipu kila, ʻo ia ka oxide kumu i hiki ʻole ke hoʻoheheʻe ʻia i ka wai.Ke hoʻokomo ʻia lākou i loko o ka waiʻawaʻawa a i ʻole ʻia me ka ʻakika ma luna o ka ʻili, hiki i kēia oxide kumu ke hoʻololi i nā hoʻololi kemika me ka waikawa.
Ma muli o ke ʻano hemo, porous, a pohā o ka unahi oxide ma luna o ka ʻili o ke kila kila a i ʻole ke kila kila haʻahaʻa, i hui pū ʻia me ka piʻi pinepine ʻana o ka unahi oxide me ke kila kaula i ka wā o ka hoʻopololei ʻana, ka hoʻopololei ʻana, a me ka lawe ʻana ma ka pickling line, hoʻonui a hoʻonui kēia mau māwae pore.No laila, hana kemika ka hoʻonā waika me ka unahi oxide a me ka hao substrate kila ma nā māwae a me nā pores.ʻO ia hoʻi, i ka hoʻomaka ʻana o ka holoi ʻana i ka waika, ʻekolu mau hopena kemika ma waena o ka pālākiō hao a me ka hao hao a me ka hoʻonā waika i ka manawa like e hana ʻia nā unahi Iron oxide i ka hopena kemika me ka waika a hemo (dissolution). e hoʻohua i ke kinoea hydrogen, ka mea e hoʻomaʻemaʻe me ka mīkini i ka pālākiō oxide (mechanical peeling effect) ʻO ka hydrogen atomic i hana ʻia e hoʻemi i ka hao iron oxides i nā ferrous oxides i hiki ke hoʻololi i ka waika, a laila hoʻopili me nā waikawa e wehe ʻia (hoʻemi).
Ⅱ-ʻO ka hoʻopaʻapaʻa/Inactivation/Deactivation
1.- ʻO ke kumu o ka passivation: Hiki ke wehewehe ʻia ke ʻano o ka passivation e ka manaʻo kiʻiʻoniʻoni ʻoniʻoni, e hōʻike ana ʻo ka passivation ma muli o ka launa ʻana ma waena o nā metala a me nā mea oxidizing, e hana ana i kahi kiʻiʻoniʻoni passivation ʻoi loa, paʻa, uhi maikaʻi, a paʻa hoʻi i hoʻopaʻa ʻia ma ka ʻili metala.Aia kēia papa kiʻiʻoniʻoni ma ke ʻano he ʻāpana kūʻokoʻa, maʻamau he hui o nā metala oxidized.He kuleana ko ia i ka hoʻokaʻawale ʻana i ka metala mai ka mea hoʻoheheʻe ʻia, ka pale ʻana i ka metala mai ka hoʻopili ʻana me ke ʻano corrosive, a laila e hoʻōki i ka hoʻoheheʻe ʻana o ka metala a hana i kahi kūlana passive e hoʻokō i ka hopena anti-corrosion.
2.- Nā pōmaikaʻi o ka passivation:
1) Hoʻohālikelike ʻia me nā ʻano hana hoʻopaʻa kino maʻamau, ʻo ka mālama passivation ka ʻano o ka hoʻonui ʻole ʻana i ka mānoanoa o ka mea hana a me ka hoʻololi ʻana i ke kala, e hoʻomaikaʻi i ka pololei a me ka waiwai hoʻohui o ka huahana, e ʻoi aku ka maʻalahi o ka hana;
2) Ma muli o ke ʻano non reactive o ke kaʻina hana passivation, hiki ke hoʻohui pinepine a hoʻohana ʻia ka mea hoʻohana passivation, e hopena i ka lōʻihi o ke ola a ʻoi aku ke kumukūʻai.
3) Hoʻoikaika ka Passivation i ka hoʻokumu ʻana o ka oxygen molecular structure passivation film ma ka ʻili metala, he paʻa a paʻa i ka hana, a he hopena hoʻoponopono ponoʻī i ka lewa i ka manawa like.No laila, ke hoʻohālikelike ʻia me ke ʻano kuʻuna o ka uhi ʻana i ka aila antirust, ʻoi aku ka paʻa o ke kiʻi passivation i hana ʻia e ka passivation a paʻa i ka corrosion.ʻO ka hapa nui o nā hopena hoʻopiʻi i ka papa oxide pili pololei a pili ʻole paha i ke kaʻina hana o ka thermal oxidation.Ma ke ana wela o 800-1250℃, ke kaʻina hana hoʻoheheʻe wela me ka hoʻohana ʻana i ka oxygen maloʻo, ka oxygen pulu, a i ʻole ka mahu wai he ʻekolu mau pae.ʻO ka mea mua, komo ka oxygen i loko o ka lewa kaiapuni i ka papa oxide i hana ʻia, a laila hoʻoheheʻe ka oxygen i loko ma o ka silicon dioxide.Ke hōʻea ʻo ia i ke kikowaena Si02-Si, hoʻopili ʻo ia me ke silika e hana i ka silicon dioxide hou.Ma kēia ʻano, hiki mai ke kaʻina hana hoʻomau o ka hoʻoheheʻe ʻana o ke komo ʻana o ka oxygen, e hoʻohuli mau ana ka silikona kokoke i ke kikowaena i loko o ka silica, a ke ulu nei ka papa oxide i loko o ka wafer silika ma kekahi ʻano.
Ⅲ- Phosphating
ʻO ka lapaʻau Phosphating kahi hopena kemika e hana i kahi papa kiʻiʻoniʻoni (phosphating film) ma ka ʻili. Hoʻohana nui ʻia ke kaʻina hana phosphating ma luna o nā ʻili metala, me ka manaʻo e hāʻawi i kahi kiʻi pale e hoʻokaʻawale i ka metala mai ka ea a pale i ka corrosion;Hiki ke hoʻohana ʻia ma ke ʻano he kumu mua no kekahi mau huahana ma mua o ka pena.Me kēia papa o ka phosphating kiʻiʻoniʻoni, hiki iā ia ke hoʻomaikaʻi i ka adhesion a me ka corrosion resistance o ka papa pena, hoʻomaikaʻi i nā waiwai hoʻonaninani, a hoʻomaikaʻi i ka ʻili metala.Hiki iā ia ke pāʻani i kahi hana lubricating i kekahi mau kaʻina hana anu metala.
Ma hope o ka hoʻomaʻamaʻa phosphating, ʻaʻole e oxidize ka mea hana a i ʻole ka ʻōpala no ka manawa lōʻihi, no laila ʻoi aku ka nui o ka hoʻohana ʻana i ka mālama phosphating a ʻo ia hoʻi kahi kaʻina hana lapaʻau maʻamau.Hoʻohana nui ʻia ia i nā ʻoihana e like me nā kaʻa, nā moku, a me ka hana mechanical.
1.- Hoʻohui a me ka hoʻohana ʻana i ka phosphating
ʻO ka maʻamau, ʻokoʻa ke kala ʻokoʻa ka mālama ʻana i ka ʻili, akā hiki ke hoʻokumu ʻia ka mālama ʻana i ka phosphating i nā pono maoli ma o ka hoʻohana ʻana i nā ʻāpana phosphating ʻē aʻe e hōʻike i nā kala like ʻole.ʻO ia ke kumu e ʻike pinepine ai mākou i ka mālama ʻana i ka phosphating i ka hina, kala, a ʻeleʻele paha.
ʻO ka hao phosphating: ma hope o ka phosphating, e hōʻike ka ʻili i ke kala a me ka uliuli, no laila ua kapa ʻia ʻo ia ka phosphorus kala.Hoʻohana nui ka phosphating solution i ka molybdate ma ke ʻano he mea maka, kahi e hana ai i kahi kiʻiʻoniʻoni phosphating kala anuenue ma luna o ka ʻili o nā mea kila, a hoʻohana nui ʻia hoʻi e pena i ka papa lalo, i mea e hoʻokō ai i ke kūpaʻa corrosion o ka mea hana a hoʻomaikaʻi i ka adhesion. o ka uhi ili.
ʻO JINBAICHENG kahi hale hana paipu kila ma Kina, Hiki iā mākou ke hana a hoʻolako i ka paipu kila maʻemaʻe, paipu welded, paipu ssaw, paipu gi me ka ʻili o ka Acid-Pʻinoʻino, ʻO ka hoʻopaʻapaʻa, a me ka Phosphating.Hāʻawi mākou i ka lawelawe kuʻuna a hāʻawi iā ʻoe i ka hopena maikaʻi loa no kāu mau papahana.E kelepona mai iā mākou no ke kumu kūʻai maikaʻi loa:https://www.sdjbcmetal.com/steel-pipe-series/ leka uila:jinbaichengmetal@gmail.com a i ʻole WhatsApp mahttps://wa.me/18854809715
