ʻO ke ʻano anticorrosion o ka pahu aila

1、 Anticorrosion o ka paia o loko o ka pahu aila
Aia nā ʻano ʻino ma ka paia o loko o kapahu ʻaila: ʻO ka corrosion hoʻopaʻa, ka mea nui ma lalo o ka pae wai o ka paia o loko o ka pahu aila, ma muli o ka ʻokoʻa o ka oxygen. ʻO ka corrosion Galvanic (electrochemical corrosion), ʻo ia ka mea nui loa a me ka pōʻino ʻino, ma lalo, paia a me luna o ka pahu. Hoʻokumu ʻia ka ʻāpana anode a me ka cathode o ka corrosion electrochemical ma muli o ka ʻokoʻa hiki ke kumu ʻia e ka micro heterogeneity o ka mea ponoʻī, aʻo ke kumu nui o ka corrosion electrochemical ka wai, ka paʻakai a me ka waikawa i loko o ka aila. ʻO ka pōʻino i hoʻokumu ʻia e ka sulfate hōʻemi i ka bacteria a me nā maʻi bacteria ʻē aʻe ka mea nui ma lalo o ka pahu. Loaʻa ka ʻino ʻino ma ka ʻāpana hoʻonui lana o ka pahu lana o ka hale.

He ʻokoʻa loa ka pale anti-static a me ka anti-corrosion i hoʻohana ʻia i loko o ka pahu o nā huahana petroleum mai nā uhi ʻoihana ʻē aʻe. Pono e hoʻokō i ʻelua mau koi: ʻo ka mea mua, me ka anti-static, pono e loaʻa iā ia ka mana anti rust maikaʻi loa no ke kila; ʻO ka uhi o loko o ka pahu i hoʻokomoʻia i loko o ka moku'āina o nā meaʻaila, aʻoi aku ka maikaʻi o ka moku i hoʻokomoʻia i ke komoʻana o ke kino kino ma o ke kiʻi pena a me kaʻinoʻino o ke kila ma mua o ke kaiapuni o ka lewa; ʻO ka lua, pono ia e kū i ka hoʻoinu ʻana i nā huahana ʻaila no ka manawa lōʻihi, ʻaʻole e hoʻohaumia a hoʻohaumia paha nā huahana ʻaila.

Hoʻokumu ʻia ka primer me ka epoxy resin i hoʻololi ʻia, ka pauka zinc a me ka mea hana curing kiʻekiʻe. ʻO ia ka corrosion-resistant ma muli o ke kumu o ka anode mōhai. ʻAʻole ʻino ʻia ka hao ma ke kūʻai ʻana i nā electrons i hoʻokuʻu ʻia e ka pauka zinc. He hoʻomaloʻo wikiwiki ka primer, maikaʻi ʻole impermeability, maikaʻi maikaʻi i ka corrosion-kūpaʻa hana a me ka adhesion ikaika. He kūpono ia no ka ʻāina mahiʻai tank. ʻO ka ʻaʻahu kiʻekiʻe o ka papahana i haku ʻia me ka resin kūikawā, ka puaʻa kūikawā a me ka hoʻopihapiha conductive, nona ka mana antistatic a me ka anticorrosive maikaʻi.2、 Anticorrosion o ka paia o waho o ka pahu wahie
ʻO ka pā waho opahu wahieAia i loko o ke kaiapuni kemika, a ʻo ke ʻano corrosion koʻikoʻi ʻo ia ka corrosion pākaukau mua, ʻoi aku ka māmā ma mua o ka pahu, akā pono ke kū ʻana o ka wā. Eia kekahi, hiki i ka wela o ka nohona o ka pahu aila anti-corrosion ke loaʻa ka hopena maikaʻi ʻole i ka huahana. No ka laʻana, ʻaʻole kūpono ka mahana kiʻekiʻe i ke kauwela i ka mālama ʻana i nā huahana aila paila haʻahaʻa, no laila pono e lawe ʻia nā ana o ka insulation wela a me ka hoʻohaʻahaʻa ʻana i ka mahana e hōʻemi ai i ka nalowale o ka aila a hōʻoia i ka palekana hana.

ʻO ka papa hana hoʻoheheʻe anti-corrosion i manaʻo ʻia no ka paia o waho o ka pahu aila: epoxy Iron Red Antirust Primer (palapala a i ʻole 2-3 mau papa, mānoanoa 80-100 μm) + epoxy micaceous iron intermediate coating (brush or spray 2-3 layers, mānoanoa 100-120 μm) a me ka hoʻopau ʻana i ka thermal-corrosion papa, mānoanoa 80-100 μm). No ka ili one omoku kaomi, hiki ke hoʻohana ʻia ka epoxy zinc rich primer (brush or spray 2-3 layers, mānoanoa 80-100 μm) Degree 80-100 μm) e hoʻonui i ka hopena anti-corrosion. He hopena pale maikaʻi ka Epoxy micaceous iron midcoat, a hiki ke pāʻani i kahi hana pale mau i ka ʻenehana anti-corrosion lōʻihi. Hiki i ka pahu insulation coating ke hoʻemi i ka mahana o ka aila (i hoʻohālikelike ʻia me ka hoʻohana ʻole ʻia o ka uhi) e 7-10 ℃ i ke kauwela a me ke kau wela kiʻekiʻe, a loaʻa iā ia ke kūpaʻa maikaʻi loa a me ka hiki ke hoʻonaninani anti-corrosion, a ua kūpaʻa ke kiʻi pena i ka hoʻoheheʻe ʻana i ka wai.
