Ma muli o ke ʻano hana, ʻeono mau ʻano kumu nui no ka pickling acid a me ka passivation o ke kila kila: ke ʻano immersion, paste method, brushing method, spraying method, circulation method, and electrochemical method.Ma waena o kēia mau mea, ʻoi aku ka maikaʻi o ke kaʻina immersion, paste method, a me ke ʻano hoʻoheheʻe ʻana no ka pickling acid a me ka passivation o nā pahu kila kila a me nā mea hana.
Ke Kaiapuni:ʻO kēia ala kūpono loa nopaipu kila kila, nā kuʻekuʻe lima, nā ʻāpana liʻiliʻi, a hāʻawi i ka hopena lapaʻau maikaʻi loa.E like me ka hiki ke hoʻokomo piha ʻia nā ʻāpana i mālama ʻia i loko o ka ʻakika pickling a me ka hopena passivation, ua hoʻopau ʻia ka hopena o ka ʻili, a ʻoi aku ka paʻakikī a me ke ʻano like o ke kiʻi passivation.He kūpono kēia ʻano hana no ka hoʻomau ʻana i ka hana ʻana akā koi i ka hoʻopiha mau ʻana i ka hopena hou i ka emi ʻana o ka neʻe ʻana o ka hopena.ʻO kāna drawback, ʻo ia ka palena o ke ʻano a me ka hiki o ka pahu waika a ʻaʻole kūpono i nā mea hana nui a i ʻole nā pipeline me nā ʻano lōʻihi a ākea paha.Inā ʻaʻole hoʻohana ʻia no ka manawa lōʻihi, hiki ke emi ka hopena ma muli o ka hoʻoheheʻe ʻana o ka hopena, e koi ana i kahi kahua i hoʻolaʻa ʻia, ka pahu wai a me nā mea hoʻomehana.
ʻAno hoʻopili: Hoʻohana nui ʻia ka ʻakika pickling paste no ke kila kila ma ka home a loaʻa i nā ʻano huahana.ʻO kāna mau mea nui e pili ana i ka waikawa nitric, hydrofluoric acid, corrosion inhibitors, a me nā mea mānoanoa, ma nā ʻāpana kikoʻī.Hoʻohana lima ʻia a kūpono no ke kūkulu ʻana ma ka pūnaewele.Ua pili i ka pickling a me ka passivation o kuhiliʻole kila pahu welds, discoloration ma hope o ka wiliwili, deck tops, kihi, make angles, alapiʻi kua, a me nā wahi nui i loko o ka wai compartments.
ʻO nā mea maikaʻi o ke ʻano paʻi, ʻaʻole ia e koi i nā mea hana kūikawā a i ʻole ka lewa, ʻaʻole pono nā mea hoʻomehana, maʻalahi ka hana ma ka pūnaewele, hoʻopau ʻia ka pickling acid a me ka passivation i hoʻokahi pae, a kūʻokoʻa.He lōʻihi ke ola o ka passivation paste, a ke hoʻohana nei kēlā me kēia noi i kahi paste passivation hou no ka hoʻohana ʻana i hoʻokahi manawa.Hoʻopau ka hopena ma hope o ka papa honua o ka passivation, e emi iho ana i ka over-corrosion.ʻAʻole i kaupalena ʻia e ka manawa holoi ʻana ma hope, a hiki ke hoʻoikaika ʻia ka passivation ma nā wahi nāwaliwali e like me nā welds.ʻO ka hemahema ʻo ia ka ʻilihune o ka hana hana no ka mea hoʻohana, kiʻekiʻe ka hana, kiʻekiʻe nā kumukūʻai, a ʻoi aku ka liʻiliʻi o ka hopena i ka mālama ʻana i ka paia i loko o nā pipeline stainless steel, pono e hui pū me nā ʻano hana ʻē aʻe.
Ke Kaʻina Paʻi:He kūpono no nā kahua paʻa, nā kaiapuni i pani ʻia, nā huahana hoʻokahi, a i ʻole nā mea hana me nā hale maʻalahi o loko no ka pickling acid a me ka passivation, e like me ke kaʻina ʻana i ka pilahi ma kahi laina hana metala.ʻO kāna mau mea maikaʻi ʻo ia ka hana hoʻomau wikiwiki, ka hana maʻalahi, ka hopena corrosive liʻiliʻi ma luna o nā limahana, a hiki i ke kaʻina hoʻololi ke pīpī hou i ka pipeline me ka waikawa.Loaʻa iā ia kahi kiʻekiʻe o ka hoʻohana ʻana i ka hopena.
