Paipu i uhi ʻia i ka zinc he pōhaku kumu no nā kenekulia, e pāʻani ana i kahi kuleana koʻikoʻi i ka lawe ʻana i ka wai, ke kinoea, a me nā wai ʻē aʻe. Eia nō naʻe, he paʻakikī koʻikoʻi ka maʻalahi o ka hao i ka corrosion. No ka lanakila ʻana i kēia palena, ua hoʻomohala nā ʻenekinia a me nā metallurgists i nā ʻano pale like ʻole, me ka zinc coating, ʻike ʻia hoʻi ʻo galvanization, e puka mai ana ma ke ʻano he hoʻokahi o nā hopena maikaʻi loa a hoʻohana nui ʻia. Hoʻopili kēia ʻatikala i nā kumu maʻamau o nā paipu hao uhi ʻia me ka zinc, e ʻimi ana i ka ʻepekema ma hope o kēia kaʻina hana a me kāna mau pono he nui.

Hōʻike pale:
Paipu i uhi ʻia i ka zinc ʻO ke kū'ē kūʻokoʻa i ka erosion ke kumu kumu no ka uhi ʻana i nā laina hao. ʻO Zinc kahi metala me ka hoʻoikaika kiʻekiʻe e hoʻoheheʻe koke ʻia i ka ea a me ka makū. ʻOiai hiki i kēia ke hāʻawi i kahi manaʻo o ka haʻalulu, ʻo ia ka mea e hana ai ka zinc i uhi makaʻala nui no ka hao. Hoʻopili paʻa ʻo Zinc i ka papa waho o kahi laina hao a hele a keakea ma waena o ka hao a me kona mau mea kaiapuni ke hoʻohana ʻia.
ʻO nā waiwai electrochemical o Zinc ka ʻepekema ma hope o kona pale ʻana mai ka hū. Hoʻopaʻa ʻia ʻo Zinc e nalowale i nā electrons ma mua o ka hao no ka mea ʻoi aku ka electronegative. E hoʻopau pono ʻia ʻo Zinc i ka ʻike ʻana i kahi electrolyte, e like me ka wai a i ʻole ka pulu i ka lewa, e nalowale ana kona hiki ke pale i ka hao huna. Ua kapa ʻia kēia quirk he cathodic security.
ʻO kahi papa o ka zinc oxide a me ka zinc carbonate i ka pae haʻahaʻa i ka pau ʻana o ka uhi zinc. Ma ka pili pono ʻana i ka paipu, hana kēia mau mea hiki ʻole ke hoʻololi i kahi pale pale hou. Hoʻonui hou ʻia ka pale ʻana o ka uhi zinc mai ka erosion e kēia pilina, i kapa ʻia ʻo passivation.
He mea kupanaha ka pale ʻana o ka zinc coating i ka ʻino. Hiki i kahi uhi zinc ke hāʻawi i ka pale no 20 a 100 mau makahiki i nā kūlana climatic maʻamau, e pili ana i ka mānoanoa a me nā kūlana kaiaola, e like me nā haʻawina. Hiki i nā laina hao i uhi ʻia i ka Zinc ke lōʻihi loa ma mua o nā laina hao i uhi ʻole ʻia, ʻoiai ma nā kūlana ʻino e like me nā ʻāpana kai me ka paʻakai kiʻekiʻe i ka lewa.
He mea nui ia no ka hoʻomanaʻo ʻana ʻaʻole pāpaʻu wale ka pale ʻana o ka uhi zinc. E hoʻomau ka zinc a puni i ka pale cathodic i ka ʻāina i uhi ʻole ʻia ʻoiai inā ua poino a pōʻino paha ka uhi zinc, e hōʻike ana i ka hao huna. ʻO nā electrifies coatings wale nō ka mea me kēia hiʻohiʻona hoʻolaʻa ponoʻī, e hoʻonui hou i ko lākou ola ma hope o kekahi manawa.
Hoʻonui i ke ola lawelawe:
paipu i uhi ʻia me ka zinc's ʻo ka corrosion re:sistance ka hopena pololei i ke ola lawelawe lōʻihi. ʻO nā paipu hao i waiho ʻole ʻia me ka pale ʻole ʻia, hiki ke hoʻololi koke i ko lākou kūpaʻa. ʻO ka hoʻokumu ʻana o ka ʻōpala ka hopena i ka lua a nāwaliwali i nā paia paipu, a laila e alakaʻi i ka leaks a i ʻole ka pau ʻole. Hiki i kēia kaʻina hana o ka pōʻino ke hiki koke mai, ʻoi aku ka nui ma nā wahi me ka nui o ka makū, ka paʻakai, a i ʻole nā kūlana waikawa.
ʻO nā paipu hao i hoʻopaʻa ʻia i ka zinc, ma ka ʻaoʻao ʻē aʻe, hiki ke mālama i ko lākou kūpaʻa paʻa no ka lōʻihi. Ke hele nei ka uhi zinc ma ke ʻano he conciliatory layer, e ʻoki mālie ana i ka wā lōʻihi me ka mālama ʻana i ka hao huna. ʻO kēia kaʻina hoʻohana lohi, hoʻomalu ʻia e hoʻonui i ke ola kōkua o ka laina.
ʻO ke ola o ka nā paipu i uhi ʻia i ka zinc ʻaʻole ia he pilikia o nā manaʻo kuhi hypothetical. Hōʻike nā hiʻohiʻona maoli i ko lākou paʻa. No ka laʻana, ʻo nā paipu kila electrifies i hoʻokomo ʻia i loko o nā hale i ka waena o ke kenekulia iwakālua he mau manawa kōkua i kēia mau lā, ma mua o hoʻokahi haneli ma hope o ka ʻoiaʻiʻo. I nā noi hou, kahi e hōʻike ʻia ai nā laina i nā kūlana ikaika hou, electrifies pipes regular outlive their uncoated partners by variables of two to four.
ʻO ke ola kōkua lōʻihi o nā paipu i uhi ʻia i ka zinc he mau hopena nui ma mua o ke ola o nā ʻāpana kū hoʻokahi. Hoʻemi ia i ka hoʻihoʻi hou ʻana o ka hoʻololi ʻana i nā laina, ka palena ʻana i nā keakea i ke kākoʻo, hoʻemi ʻana i nā kumukūʻai mālama, a me ka hoʻololi ʻana i nā waiwai. ʻO nā pono kumulative o kēia ola lawelawe lōʻihi hiki ke lilo i mea nui i nā papahana ʻoihana nui e like me nā ʻōnaehana wai kūloko a i ʻole nā mea hana ʻoihana.
Eia kekahi, kōkua ʻia nā hana e mālama i ke kaiapuni e ka lōʻihi o nā paipu i uhi ʻia i ka zinc. Ma ka hōʻemi ʻana i ke koi no ka hoʻololi mau ʻana, ʻoi aku ka liʻiliʻi o ka ikehu a me nā ʻāpana i hoʻomaʻemaʻe ʻole ʻia i ka wā lōʻihi, e koi ana i ka hopena haʻahaʻa haʻahaʻa a nui. I ka nānā ʻana o nā ʻoihana a me nā aupuni i ka hoʻohaʻahaʻa ʻana i kā lākou kapuaʻi kalapona a me ka hoʻonui ʻana i ka pono waiwai, ua lilo kēia ʻano i mea nui.
Māmā e mālama:
ʻO kekahi o nā pōmaikaʻi nui o nā paipu hao i uhi ʻia i ka zinc ʻo ko lākou maʻalahi o ka mālama ʻana. ʻAʻole pale wale ka papa zinc pale i ka corrosion akā maʻalahi hoʻi i ka mālama mau ʻana a me ka hoʻoponopono ʻana o ka ʻōnaehana paipu. ʻO kēia hiʻohiʻona he mea nani loa nā paipu galvanized no nā noi kahi i kaupalena ʻia ke komo ʻana i ka mālama mau ʻana a i ʻole kahi e hoʻemi ʻia ai ka manawa haʻahaʻa o ka ʻōnaehana.
Hoʻokumu ka zinc coating i kahi ʻano like ʻole, paʻa paʻa ma luna o ka ʻili holoʻokoʻa o ka paipu hao. ʻAʻole hiki ke hōʻiliʻili i nā waihona a i ʻole ka unahi ʻana o kēia ʻili maʻemaʻe ke hoʻohālikelike ʻia me nā paipu hao i uhi ʻole ʻia. Ma nā ʻōnaehana hoʻohele wai, hiki i kēia ke kōkua i ka mālama ʻana i nā kahe kahe a hoʻemi i ke kūkulu ʻana o nā waihona mineral i ka manawa. ʻO ka ʻili maʻemaʻe nō hoʻi e maʻalahi ka hoʻomaʻemaʻe inā pono, inā ma o ka mīkini a i ʻole ka mālama kemika.
I ka hopena o ka pōʻino i ka zinc coating, hiki ke hana maʻalahi ka hoʻoponopono kūloko me ka ʻole o ka pono e pani i nā ʻāpana paipu holoʻokoʻa. Hiki ke hoʻoponopono ʻia nā wahi liʻiliʻi o ka pōʻino, e like me nā ʻōpala a i ʻole nā corrosion kūloko, me ka hoʻohana ʻana i nā pena a i ʻole nā sprays waiwai nui o ka zinc. Loaʻa i kēia mau huahana nā ʻāpana kiʻekiʻe o ka zinc e hāʻawi i ka pale cathodic e like me ka uhi galvanized kumu. No nā wahi nui o ka pōʻino, hiki ke hoʻohana ʻia nā ʻenehana e like me ka hoʻoheheʻe ʻana (ka hoʻoheheʻe ʻana i ka zinc i hoʻoheheʻe ʻia ma luna o ka ʻili) e hoʻihoʻi hou i ka papa pale.
ʻO nā waiwai hoʻōla ponoʻī o nā pani zinc e kōkua pū i ko lākou maʻalahi o ka mālama ʻana. Inā ʻoki ʻia a ʻāwili ʻia ka uhi, e hōʻike ana i ka hao o lalo, e hoʻomau ka zinc a puni i ka pale cathodic i ka wahi i ʻike ʻia. 'O ia ho'i, 'a'ole hiki i ka poino li'ili'i o ka uhi ke ho'ololi koke i ke kū'ē'ana o ka paipu, e hā'awi ana i nā hui mālama i ka ma'alahi o ka ho'oponopono 'ana.
ʻO kekahi ʻano o ka maʻalahi o ka mālama ʻana nā paipu i uhi ʻia i ka zinc ʻo ko lākou kūlike me nā ʻano hui like ʻole. Hiki ke hoʻopaʻa ʻia nā paipu Galvanized, hoʻopaʻa ʻia, a hoʻohui ʻia me ka hoʻohana ʻana i nā hui mechanical. Ma hope o ka hui ʻana, hiki ke pale ʻia nā wahi i hōʻike ʻia me ka hoʻohana ʻana i nā pūhui zinc-rich, e hōʻoiaʻiʻo ana i ka pale mau ma ka lōʻihi o ka ʻōnaehana paipu.
ʻO nā mea hana paipu i uhi ʻia e Zinc:
I ka wā e loaʻa ai nā paipu i uhi ʻia i ka zinc, nui nā mea hana ma ka honua holoʻokoʻa e hāʻawi ana i nā ʻano huahana e kūpono i nā noi like ʻole. ʻO kekahi o ia mea hana ʻo ka Longma Group, nāna e hoʻolako i nā paipu i uhi ʻia i ka zinc e pili ana i nā kūlana hoʻonaninani honua. Aia kēia mau maʻamau i ka DIN30670, DIN30678, CSAZ245.20, EN10339, ISO21809-1, AWWAC210, a me C213, e hōʻoia ana i kā lākou huahana e hoʻokō i nā kūlana koʻikoʻi a me nā pae hana.
