He aha ka mea e hoʻolilo ai i ka paipu kila galvanized i koho maikaʻi loa no ka plumbing?

I ke koho ʻana i nā mea hana no nā paipu wai,paipu kila galvanizedua lilo ia i mea punahele i waena o nā mea kūkulu hale a me nā mea hana hana no nā makahiki. ʻO nā mea ʻeluapaipu galvanizeda mepaipu galvanized, ua ulu aʻe mai ka maʻamaupaipu kila, kū i waho no ko lākou pono kūpono a me ka hana hilinaʻi i nā papahana hoʻolako wai a me nā papahana hoʻokahe wai o kēlā me kēia lā.

ʻO ka mea e hoʻokaʻawale ai i kēia mau paipu, ʻo ia ke ʻano hana galvanizing wela-luʻu. I ka hoʻomaka ʻana, hele ka paipu kila maka i ka pickling e wehe i ka oxide hao o luna. A laila hoʻomaʻemaʻe ʻia me ka hopena kemika ʻoihana ma mua o ka hoʻokomo ʻia ʻana i loko o ka pahu plating wela-luʻu. I loko o ka pahu, launa pū ke kumu kila me ka zinc heheʻe ma o nā loli kino a me nā kemika, e hana ana i kahi papa zinc-hao paʻa. Hoʻopili pono kēia papa me ka uhi zinc maʻemaʻe a me ke kino paipu. ʻO ka hopena hope loa he ʻili i uhi like ʻia me ka hoʻopili ikaika, ka hiki ke pale i ka palaho maikaʻi loa a me ke ola lawelawe lōʻihi, e hoʻololi pono ana i nā wahi plumbing humid a paʻakikī.

Me ke keʻena nui ma ka ʻĀpana ʻo Shanghai Yangpu, ua hoʻokumu ʻia ʻo ZZ Group i ka hoʻomaka ʻana o nā makahiki 1980. Me kahi kapikala i hoʻopaʻa inoa ʻia he 200 miliona RMB, uhi kēia hui nui i ke kālepa kila, ka hana ʻana, ka waiwai paʻa a me ka hoʻopukapuka kālā. Ma ke ʻano he mea pāʻani kiʻekiʻe ma ka ʻāpana mea hao o Kina, ua loaʻa iā ia nā inoa e like meʻOihana Hilinaʻi 100 Kiʻekiʻe Loa o ka ʻĀinaa meNā ʻoihana pilikino 100 kiʻekiʻe loa o ShanghaiHāʻawi mākou i nā huahana galvanized kiʻekiʻe i nā mea kūʻai aku ma ka ʻāina holoʻokoʻa.

Ma muli o nā mea a pau, me ka hana lima paʻa a me ka hana paʻa, ʻo ka paipu kila galvanized ka koho kūpono loa a hilinaʻi hoʻi no nā noi plumbing hou.
