He aha ka ʻokoʻa ma waena o ka pepa galvanized a me ka ʻili kila?

ʻO ka pepa Galvanized e pili ana i kahi pā kila mānoanoa me kahi papa zinc i uhi ʻia ma ka ʻili.ʻO ka hot-dip galvanizing kahi ʻano lapaʻau anti-rust kūpono i koho pinepine ʻia.Ma kahi o ka hapalua o ka hana zinc o ka honua i hoʻohana ʻia i kēia hana.
ʻO ka pepa Galvanized e pale i ka corrosion ma ka ʻili o ka pā kila mānoanoa a hoʻonui i kona ola lawelawe.Hoʻopili ʻia ka ʻili o ka pā kila mānoanoa me kahi papa zinc metala.Ua kapa ʻia kēia ʻano pā kila mānoanoa me ka zinc-coated he galvanized sheet.
E like me ka hana a me ka hana ʻana, hiki ke hoʻokaʻawale ʻia i nā ʻāpana:
① Paʻa kila mānoanoa me ka wela wela.Hoʻokomo ʻia ka ʻāpana kila i hoʻoheheʻe ʻia i loko o ka ʻauʻau zinc i hoʻoheheʻe ʻia, no laila e hoʻopili ʻia ka ʻili o ka pale kila i hoʻopili ʻia me kahi papa zinc.I kēia pae, ʻo ke kī ʻo ia ka hoʻohana ʻana i ke kaʻina hana galvanizing wela hoʻomau no ka hana ʻana, ʻo ia hoʻi, ʻo ka pā kila mānoanoa i loko o kahi pā e hoʻomau mau ʻia i loko o kahi pahu plating me ka zinc hehee e hana ai i kahi pepa galvanized;
②Pepa galvanized i hoʻoikaika ʻia i ka palaoa.Hana ʻia kēia ʻano pā kila mānoanoa e ke ʻano wela wela, akā ma hope koke o ka puka ʻana i waho o ka pahu, ua wela ia ma kahi o 500 ° C e hoʻohuli ai i kahi kiʻiʻoniʻoni alumini alumini o ka zinc a me ka hao.ʻO kēia ʻano pepa galvanized ka hoʻopili maikaʻi ʻana o nā uhi hale kūkulu hale a me ka wili uila;
③ Pepa uila uila.ʻO ka hana ʻana o kēia ʻano pepa galvanized e ka electroplating he hana maikaʻi loa.Eia naʻe, lahilahi ka uhi ʻana, a ʻaʻole maikaʻi ke kūpaʻa ʻana i ka corrosion e like me ka pale wela wela;
④Pepa galvanized ʻaoʻao hoʻokahi a ʻelua ʻaoʻao.ʻO ka ʻaoʻao hoʻokahi a me ka ʻaoʻao ʻelua, ʻo ia hoʻi, nā waiwai i hoʻopaʻa ʻia ma ka ʻaoʻao hoʻokahi wale nō.Ma ke ʻano o ka hoʻoheheʻe uila, ka hoʻoulu ʻana, ka mālama anti-rust, ka hana ʻana a me ka hana ʻana, a me nā mea ʻē aʻe, ʻoi aku ka ikaika o ka adaptability ma mua o ka pepa galvanized ʻaoʻao ʻelua.I mea e pale aku ai i ka hemahema o ka zinc uncoated ma nā ʻaoʻao ʻelua, aia kekahi ʻano ʻāpana galvanized i uhi ʻia me ka zinc chromatographic ma kēlā ʻaoʻao, ʻo ia hoʻi, ka pepa galvanized me ka ʻokoʻa ma nā ʻaoʻao ʻelua;
⑤ Aluminum huila, composite galvanized pepa.Hana ʻia ia me ka zinc a me nā mea metala ʻē aʻe e like me ke aluminika, ke alakaʻi, ka zinc, etc.ʻO kēia ʻano pā kila mānoanoa he mau hiʻohiʻona lapaʻau anti-rust ʻē aʻe a me nā hiʻohiʻona maikaʻi hoʻopuʻi;
Ma waho aʻe o nā mea ʻelima i luna, aia kekahi pepa galvanized waihoʻoluʻu, paʻi ʻaʻahu i hoʻoheheʻe ʻia i ka pepa galvanized, polyethylene laminated galvanized sheet a pēlā aku.Akā i kēia manawa, ʻo ka mea maʻamau ka mea maʻamau i ka wela-dip galvanized sheet.
ʻO ka pā kila kila ka inoa maʻamau o ke kila kuhiliʻole ʻakika, kūpaʻa i nā mea ʻino nāwaliwali e like me ke kinoea, ka mahu, ka wai, a i ʻole nā ​​​​papa kila me nā waiwai kila kila i kapa ʻia he pā kila kila;ʻoiai ʻo nā mea hoʻoheheʻe-kūʻai (acid, alkali, paʻakai a me nā mea hoʻoheheʻe kemika ʻē aʻe) ) ua kapa ʻia nā mea kila i kālai ʻia he mau kila-kūpono.
Ma muli o ka ʻokoʻa o ka haku mele ʻana o nā mea ʻelua, ʻokoʻa ko lākou pale ʻana i ka corrosion.ʻO ka mea maʻamau, ʻaʻole kūpaʻa nā pā kila kuhiliʻi i ka ʻānai ʻana, ʻoiai ʻo nā kila kūpaʻa ʻakika maʻamau, loaʻa nā waiwai kila kila.ʻO ka huaʻōlelo "stainless steel plate" ʻaʻole wale e pili ana i kahi ʻano pā kila kila, akā hōʻike pū ʻia ma mua o 100 mau ʻano o nā papa kila kila.E loaʻa i kēlā me kēia pā kila stainless i kūkulu ʻia a hoʻolālā ʻia nā hiʻohiʻona maikaʻi loa no kāna kumu nui kūikawā.ʻO ke kī i ka holomua, ʻo ia ka ʻike mua ʻana i ka hoʻohana mua ʻana, a laila ka pae kila kūpono.ʻEono wale nō nā māka kila e pili ana i ke kumu nui o ke kūkulu hale.Loaʻa iā lākou a pau he 17-22% chromium, a he nickel hoʻi nā māka kila maikaʻi.ʻO ka hoʻohui ʻana i ka molybdenum e hoʻomaikaʻi hou i ka ʻino o ka ea a kūpaʻa loa i ka ea fluoride.
ʻO ka pā kila kila ʻole e pili ana i ke kila i kū ʻole i nā mea ʻino nāwaliwali e like me ke kinoea, ka mahu, a me ka wai, a me nā mea hoʻoheheʻe kemika kūlohelohe e like me ka waikawa, ka alkali, a me ka paʻakai, ʻike ʻia hoʻi ʻo ke kila kila waikona.Ma nā noi kikoʻī, kapa pinepine ʻia ke kila kūʻē i nā mea corrosive nāwaliwali, a ʻo ke kila kūʻē i ka solvent corrosion i kapa ʻia ʻo ka acid-resistant steel.Ma muli o ka ʻokoʻa o ka haku mele ʻana ma waena o nā mea ʻelua, ʻaʻole pono ka mea mua i ke kūʻē ʻana i ka hoʻoheheʻe ʻana, ʻoiai ʻo ka mea maʻamau he stainless.ʻO ka pale ʻana i ka corrosion o nā pā kila kila i loko o nā mea alumini alumini i loko o ke kila.
