Nā ʻokoʻa ma waena o ke keleawe a me ke alumini Radiator

I kēia manawa, nui nā mea hana ma ka mākeke i hoʻohālikelike ʻia me nā radiators alumini.ʻIke mākou a pau ʻaʻole i like ka thermally conductive o nā radiator alumini e like me ke keleawe.No laila ʻo wai ka lōʻihi o ke ola lawelawe?E pili ana ka helu heheʻe haʻahaʻa o ka alumini i ke ola lawelawe?ʻO ka helu heheʻe o ke keleawe he 1084.4°C, a ʻo ko aluminika he 660.4°C.Eia nō naʻe, no ka loaʻa ʻana o ka mea hoʻoheheʻe diesel i nā mea pale overheating, ʻaʻole ia e hiki i kēia wela.ʻO ka mea ʻē aʻe, ʻo ka wai wela kiʻekiʻe e hoʻoholo i ke ola radiator.ʻAʻole wai maʻemaʻe ka wai i ko mākou ola i kēlā me kēia lā.Loaʻa iā ia nā ion like ʻole, ʻoi aku ka nui o nā ion chloride.Ke hoʻopili ʻia ke keleawe me nā ion hoʻoikaika e like me Cl- a me SO42- i loko o ka wai, e hoʻopuka ʻo ia i nā ion hoʻoikaika i loko o kēia mau ʻiona hana.Hoʻohua ka wai i ka waika.ʻO ka SO2, CO2, a me H2S i ka lewa i hoʻoheheʻe ʻia i ka wai e hōʻemi pū i ka waiwai PH kūloko.ʻO ke komo ʻana i loko o ke keleawe e hoʻolalelale i ka ʻino o ke keleawe a hoʻoulu i ka pala i loko o ka radiator keleawe a me ka paipu wai wela keleawe.

ʻO ka radiator alumini o mīkini hana hana ʻAʻole hiki ke pale i ka ʻinoʻino o ka wai, a na Cl- e hoʻopau i ke kiʻi pale o ka alumini.Hoʻokomo ʻo Cl- i loko o ke kiʻi pale ma o nā pores a i ʻole nā ​​hemahema ma ka ʻili alumini, no laila e colloidal a hoʻopuehu ka kiʻi pale ma ka ʻili alumini.ʻO ke kiʻi pale Al2O3 e komo i ka hydration a lilo i oxide hydrated, e hoʻemi ana i ka hopena pale.Eia kekahi, ʻo ka Cu2 + i hana ʻia ma hope o ka ʻāʻī ʻana o nā ʻāpana keleawe e hoʻolalelale i ka corrosion pitting o ka alumini.Eia kekahi, hoʻopili ʻia ka SO2 i ka lewa e ka kiʻiʻoniʻoni wai ma ka ʻili alumini, e hoʻoheheʻe ʻia e hoʻohua i ka H2SO3 (sulfurous acid) a me ka hana ʻana me ka oxygen e hoʻohua ai i ka H2SO4 e hoʻopau i ka ʻili alumini.Ke hoʻopau ʻo Cl- me ka hoʻopuehu ikaika a me ka mana komo i ke kiʻi ʻoniʻoni pale alumini, pili hou ʻo SO2- me ka matrix alumini, a hiki ke ʻino.Hoʻonui kēia pōʻai i ka ʻino o ka alumini.No ka mea, ʻoi aku ka kiʻekiʻe o ke kaʻina hana corrosion o ka alumini ma mua o ke keleawe, ma lalo o ka hana a nā electrolytes e like me ka wai, ke hoʻopili ʻia ka alumini i kēia mau metala, ua hoʻokumu ʻia kahi hui galvanic.ʻO ka alumini ka anode.ʻO ka ʻinoʻino Galvanic e hōʻeha koke i ka ʻino o ka alumini.No laila, ʻaʻole i like ka lōʻihi o ke ola o ka radiator alumini e like me ke ola o ka radiator keleawe.

ʻO nā ʻokoʻa ma waena o ke keleawe a me nā radiator pahu wai alumini: ʻokoʻa ka hopena wela, ʻokoʻa ka lōʻihi a me nā antifreeze ʻokoʻa.

1. Nā hopena wela wela

1.1. ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka pahu wai keleawe a pau: ʻoi aku ka maikaʻi o ka hopena wela o nā pahu pahu wai keleawe a pau ma mua o nā mea hoʻoheheʻe pahu wai alumini.ʻOi aku ka maikaʻi o ka hopena wela o ke keleawe ma mua o ka alumini, ʻoi aku ka maʻalahi o ka hoʻopau ʻana i ka wela.

1.2.All alumini pahu wai radiator: ka wela dissipation hopena o nā mea a pau alumina wai pahu radiator ua oi aku ka ino ma mua o ka keleawe a pau pahu wai pahu radiator, a me ka wela conduction hopena o ka aluminika ma mua o ke keleawe, no laila, 'aʻole i maʻalahi ka hemo. wela.

2.ʻokoʻa ka lōʻihi

2.1.ʻOi aku ka maikaʻi o ka radiator pahu wai keleawe a pau: ʻoi aku ka maikaʻi o ka radiator pahu wai keleawe a pau ma mua o ka radiator pahu wai alumini.ʻOi aku ka ʻoi aku o ka ʻeleʻele keleawe a me ke kūpaʻa corrosion kiʻekiʻe.

2.2 ʻOi aku ka ʻino o ka pahu pahu wai alumini a pau: ʻoi aku ka maikaʻi o ka lōʻihi o ka pahu pahu wai aluminika a pau ma mua o ka radiator pahu wai keleawe a pau.Wehe loa ka papa alumini oxide a haʻahaʻa ka pale ʻana i ka corrosion.

Heʻokoʻa ka 3.Antifreeze

3.1.ʻO ka mea hoʻoheheʻe pahu wai keleawe a pau: hiki i nā mea hoʻoheheʻe pahu wai keleawe a pau ke hoʻohana i ka wai ma ke ʻano he antifreeze me ka ʻole e ālai i ka pahu wai.

3.2.ʻAʻole hiki ke hoʻohana i ka wai hoʻoheheʻe pahu wai alumini a pau: ʻaʻole hiki ke hoʻohana ʻia nā mea hoʻoheheʻe wai alumini a pau ma ke ʻano he antifreeze, akā pono e hoʻohana i ka antifreeze kūpono.ʻO ka hoʻohui ʻana i ka wai e hoʻopaʻa ʻia ka pahu wai.

E like me ka hoʻokaʻawale ʻana: ua māhele ʻia ka radiator o ka ʻōnaehana hoʻoheheʻe ʻana i ka pahu wai keleawe a me ka pahu wai alumini.

E like me ka hoʻokaʻawale ʻana o ka hoʻolālā radiator, ua hoʻokaʻawale ʻia ka radiator o ka ʻōnaehana hoʻoluʻu ʻenekini i ke ʻano kāʻei tube a me ke ʻano ʻano pā.Hoʻohui pū ʻia me nā mea, ʻo ka radiator maʻamau o ka ʻōnaehana hoʻomehana ʻenehana i ka mākeke ʻo ia ka nui o ke kāʻei paipu keleawe, ke kāʻei paipu alumini a me ka pā pāpaʻi alumini.

ʻO nā pono o ka radiator pahu wai keleawe:

ʻO ka paipu keleawe me ka pahu wai, ka hoʻokele wela wikiwiki a me ka hana hoʻopau wela maikaʻi.Hiki ke hoʻohana ʻia ka wai ma ke ʻano he antifreeze

I kēia manawa, ʻaʻohe keleawe maʻemaʻe a me ka alumini nā pahu wai radiators , ua hoʻohui ʻia nā mea a pau me nā mea ʻē aʻe.

ʻOi aku ka liʻiliʻi o ke kumukūʻai holoʻokoʻa o ka pahu wai alumini ma mua o ka pahu wai keleawe.He kūpono ia no ka radiator wahi nui.Loaʻa ka hilinaʻi maikaʻi a me ka lōʻihi o ka pahu wai pahu alumini.

ʻAʻohe mea kānalua ʻoi aku ka nui o nā radiator keleawe ma mua o nā radiators alumini.Me ka holomua o ka ʻenehana pahu wai alumini, ua hoʻomaka kekahi mau ʻoihana e noʻonoʻo ana i nā kumukūʻai hana e hoʻohana nui i ka radiator tank wai alumini.

ʻOi aku ka maikaʻi o ke keleawe ma mua o ka alumini.ʻO ke kumu nui ʻo ia ka wehe ʻana o ka papa o ka alumini, ʻoi aku ka paʻa o ka ʻāpana o ke keleawe, a ʻoi aku ka kiʻekiʻe o ke kūpaʻa ʻana o ke keleawe keleawe ma mua o ka alumini.No laila, i loko o ka wahi corrosive liʻiliʻi, e like me ka wai maoli, nāwaliwali ka waika, nāwaliwali alkali solution a me ka paʻakai paʻakai, e hoʻomau ʻia ka alumini a hiki i ka ʻāʻī ʻana, ʻoiai ʻaʻole maʻalahi ka pōʻino o ka papa keleawe o ke keleawe, ka substrate. ʻoi aku ka maikaʻi o ka corrosion-resistant a maikaʻi ke kūpaʻa kūlohelohe.

No laila, ke noʻonoʻo ʻoe e hoʻohana i ke ʻano o ka radiator, hiki iā ʻoe ke hoʻoholo e like me kāu mau koi, e like me ke kūlana hoʻonohonoho ma ka pūnaewele, ka ʻoihana hana a me nā mea ʻē aʻe. .com, e alakaʻi mākou iā ʻoe e koho i kahi huahana kūpono.
