Hiki ke ʻino ʻia o ka tinplate

Hoʻokumu ʻia ka corrosion o nā huahana metala e ka instability electrochemical o ka mea i loko o ka ʻike corrosive.ʻO nā mea nui e pale ai i ka corrosion o ka pahu tinplate ʻekolu ʻāpana ʻo ia ka uhi ʻana o ke kino pahu, ka papa tinplate plating a me ka papa hao, a me ka uhi luna a me ka uhi lalo i loko o ka uhi.No ka mea, loaʻa i nā huahana pale metala ke ola o ke ola, ke hiki i ka tin ke hoʻolālā i ke ola corrosion ʻoi aku ka nui ma mua o ke ola o ka papa e hiki ai ke hoʻokō i nā koi o ka hana ʻana, e hōʻoia i ka maikaʻi a me ka palekana o ka meaʻai a me ka mea inu i ka wā o ke ola, ʻoi aku ka nui o ka corrosion. ʻO ka margin ka maikaʻi o ka maikaʻi, hoʻonui i ke kumukūʻai waiwai o nā huahana.I mea e noʻonoʻo ai i nā koi o ke ola hoʻolālā kūpono a me ka mālama ʻana i ka waiwai i ka manawa like, ʻo ka hana ʻana o nā tinplate ʻekolu mau ʻāpana i nā koi kūpono no nā mea maka a me nā kaʻina hana, a mālama i ka maikaʻi o nā huahana.

Hōʻike ka hana hoʻokolohua ʻo ka uhi ʻana, ka papa tinning a me ka papa hao o ka tinplate nā pale pale corrosion nui o ka pahu.Hiki i nā mea waiwai paʻa a me nā ʻenehana kūpono ke hoʻokō i nā koi kūpaʻa corrosion o ka hapa nui o nā huahana pahu paʻa.Ua ʻike pū ʻia nā noiʻi e pili ana i ka ʻino i loko o ka pahu o kekahi mau huahana i hana mua ʻia, ma muli o nā ʻano ʻino like ʻole a me kahi o ka hanana ʻana, ʻokoʻa loa kona ulu ʻana, ua hoʻopuka kekahi mau pahu paʻa i nā ʻōpala i loko o kekahi mau pule, koʻikoʻi. ʻO ka ʻinoʻino ma hope o kekahi mau mahina e ʻike ʻia ke ʻano o ka corrosion perforation, hiki ke hoʻomau i ka ʻino ʻana o ka pahu paʻa i ke ola o ka papa ma hope o ka hiki ʻole o ka corrosion perforation.I ke kaʻina hana a me ka mālama ʻana i nā pahu tinplate, ʻike pinepine ʻia e loaʻa ka pahu pahu ma mua o ka hiki ʻana i ke ola o nā kini paʻa, a ua māhele ʻia nā ʻano corrosion nui i ka corrosion like a me ka corrosion kūloko.He pōʻino ka ʻino kūloko i ka maikaʻi a me ka palekana o ka pahu, a hiki ke alakaʻi i ka ʻino a me ka leakage perforation i ka wā o ke ola o ka pahu.

1. ʻAi like ʻole

ʻO ka corrosion uniform, ʻike ʻia hoʻi ʻo ka corrosion piha, ua māhele ʻia ke ʻano corrosion ma luna o ka ʻili metala holoʻokoʻa, ʻano like ka nui o ka corrosion o kēlā me kēia ʻāpana o ka ʻili metala, ʻoi aku ka lahilahi o ka ʻili metala, a ʻaʻole maopopo ka ʻili metala. ʻokoʻa i ka morphology corrosion, maʻalahi ka ʻimi ʻana a me ka mālama ʻana o ia ʻano palaka no ka mea aia ma luna o ka ʻili āpau.ʻO ke ʻano corrosion maʻamau i loko o ka tinplate hiki ke corrosion ʻo ia ka corrosion like ʻole, ka mea i hana nui ʻia ma ka ʻāʻī ma ka piko o ke kino hiki, ka wahi deformation ma lalo o ke kino hiki a me ke kūlana o ka wahi weld coating.

2. Kaʻino kūloko

ʻO ka corrosion kūloko, ʻike ʻia hoʻi ʻo ka corrosion non-uniform, ma muli o ke ʻano like ʻole o ka hana electrochemical, e like me nā metala like ʻole, nā hemahema o ka ʻili, nā ʻokoʻa ʻokoʻa, ka ʻike kaumaha a i ʻole ka like ʻole o ke kaiapuni.Hiki ke hoʻokaʻawale ʻia ka ʻino a me ka anode o ka corrosion kūloko, ʻike ʻia ka corrosion kūloko i kahi kikoʻī, hiki koke mai, hoʻopau koke ʻia ka mea, a hiki i ka corrosion kūloko o ka tinplate ke alakaʻi maʻalahi i ke ʻano leakage perforation.Hāʻawi ka corrosion kūloko i nā ʻano ʻano like ʻole, e like me ke ʻano o ka ʻino o ka corrosion kūloko, hiki ke hoʻokaʻawale ʻia kēlā ʻano corrosion i loko o ka uila uila, pore corrosion, seam corrosion, intergranular corrosion, wear corrosion, stress corrosion, fatigue corrosion a koho koho.

ʻO ka corrosion kūloko o nā pahu tinplate ka hapa nui i ka weld a i ʻole ke apo hoʻonui o ka uhi lalo o ka pahu, kahi o ka corrosion lalo ka wahi nui o ka corrosion perforation, e like me ka hōʻike ʻana ma ke kiʻi ma lalo, ke kikowaena o ka ʻeleʻele. ʻike ʻia ka ʻāpana corrosion i nā lua corrosion, i hoʻohālikelike ʻia me ka ʻāpana corrosion ʻaʻahu, he liʻiliʻi loa ka ʻāpana corrosion, he ʻano maʻamau o ka corrosion kūloko, ʻo ka hoʻomohala mau ʻana o ka corrosion e alakaʻi i ka perforation tank corrosion.
ʻO ka maʻamau, kakino-welder a me ka coater o Changtai akamai no ka hiki-hana lako， ʻO nā mea hana maikaʻi loa e hoʻoponopono i nā pilikia ma luna, e ʻoluʻolu e nīnau i ka ʻenehana ʻenehana changtai Company i ka hoʻoponopono ʻana i kēia pilikia.
