Paipu galvanized wela

Hoʻopili ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana i kahi papa paʻa, i hui ʻia ka matrix a me ka uhi. Hot dip galvanizing ʻo ia ka pickling mua i ka paipu kila, i mea e wehe ai i ka oxide hao ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, ma o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia ka pahu wai wai no ka hoʻomaʻemaʻe. a laila i loko o ka pahu hoʻoheheʻe wela. Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi. ʻO ka hapa nui o nā kaʻina hana ma ke kūkulu ʻākau e hoʻohana i ke kaʻina hana hoʻopiha zinc o ke kāʻei galvanized.

Paipu galvanized anu

Cold galvanized mea uila galvanized, galvanized nui ka liʻiliʻi loa, 10-50g/m2 wale nō, ʻokoʻa kona kūʻē corrosion ma mua o ka paipu galvanized wela. ʻO nā mea hana paipu galvanized maʻamau, i mea e hōʻoiaʻiʻo ai i ka maikaʻi, ʻaʻole hoʻohana ka hapa nui i ka galvanizing uila (ke anu anu). ʻO kēlā mau ʻoihana liʻiliʻi wale nō me nā mea hana kahiko e hoʻohana i ka galvanizing uila, ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o kā lākou kumukūʻai. I ka wā e hiki mai ana, ʻaʻole ʻae ʻia nā paipu galvanized anuanu e hoʻohana ʻia e like me nā paipu wai a me ke kinoea.

ʻO ka paipu kila galvanized wela

Hiki ke hoʻololi kino a me ke kemika paʻakikī ma waena o ka pahu kila a me ka ʻauʻau i hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao paʻa me ka pale ʻana i ka corrosion. Hoʻohuiʻia ka papa'āpana me ka'āpana zinc maʻemaʻe a me ka matrix paipu kila. No laila, ikaika kona pale ʻana i ka corrosion.

Ma hope o ka hoʻomohala ʻana o ka paipu kila galvanized wela i ka 1960s a 1970s, ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka huahana, 1981 a 1989 i hāʻawi ʻia i ke Kuhina metallurgical o nā huahana kiʻekiʻe a me ka makana kālā aupuni, ua hoʻonui ʻia ka hana no nā makahiki he nui, 1993 huahana o nā mea hou aku. ma mua o 400,000 tons, 1999 puka o ka ʻoi aku ma mua o 600,000 tons, a lawe ʻia aku i Asia Hema, ʻApelika, ʻAmelika Hui Pū ʻIa, Iapana, Kelemānia mau ʻāina a me nā ʻāina. Hoʻohana nui ʻia nā paipu galvanized wela e like me nā paipu wai a me nā paipu kinoea, a ʻo nā kikoʻī maʻamau he +12.5 ~ + 102 mm. Ma hope o nā makahiki 1990, ma muli o ka nānā ʻana o ka mokuʻāina i ka mālama ʻana i ke kaiapuni, ʻoi aku ka paʻakikī o ka hoʻomalu ʻana i nā ʻoihana pollution kiʻekiʻe, ʻo nā "ʻekolu ʻōpala" i hana ʻia i ka hana ʻana i nā paipu galvanized hot-dip he paʻakikī ke hoʻoponopono, hui pū me ka ka hoʻomohala wikiwiki ʻana o nā paipu wiliwili kila, nā paipu PVC a me nā paipu hui, a me ka mokuʻāina e hoʻolaha i ka noi ʻana i nā mea hana hale kemika, ua kaupalena ʻia ka hoʻohana ʻana i nā paipu kila kila, e hana ana i ka hoʻomohala ʻana i nā paipu welded hot-dip welded pipes. i hoʻopili ʻia ʻo Beam a me ka palena, wela hoʻi i hoʻopaʻa ʻia i ka paipu welded ma hope ua hoʻomohala mālie.

Paipu kila galvanized anu

ʻO ka papa zinc he uhi uila, a ua hoʻopaʻa kūʻokoʻa ka papa zinc me ka matrix paipu kila. He lahilahi ka papa zinc, a ua hoʻopili wale ʻia ka papa zinc i ka matrix tube kila a maʻalahi ke hāʻule. No laila, ʻilihune kona pale ʻana i ka corrosion. I nā hale noho hou, pāpā ʻia ka hoʻohana ʻana i nā paipu kila galvanized anuanu e like me nā paipu wai.
