ʻO ka galvanizing welahe kaʻina hana e hoʻokomo ʻia ai kahi mea metala a ʻāpana paha me ka ʻili maʻemaʻe i loko o kahi solution zinc i hoʻoheheʻe ʻia, a ua hoʻokumu ʻia kahi papa o ka zinc metala ma ka ʻili ma o ka hopena kino a me ke kemika ma ka interface. ʻO ka galvanizing Hot-dip, ka mea i ʻike ʻia he hot-dip galvanizing a me ka hot-dip galvanizing, he ʻano hana anti-corrosion maikaʻi, i hoʻohana nui ʻia no ka anti-corrosion ili o nā hale metala, nā lako a me nā mea i nā ʻoihana like ʻole. No laila he aha nā ʻano opaipu kila maʻemaʻe ʻole?

1. ʻO nā ʻāpana hina o nā ʻano nui like ʻole ma luna o ka ʻili o ka paipu kila seamless galvanized ka ʻokoʻa kala o ka galvanizing, kahi pilikia paʻakikī i ka ʻoihana galvanizing o kēia manawa, pili nui i nā mea i loaʻa i loko o ka paipu kila ponoʻī a me nā mea i loko. ka ʻauʻau zinc. ʻAʻole pili ka ʻili i ka hana anti-corrosion o ka paipu kila, ʻo ka ʻokoʻa wale nō i ka helehelena.

2. Aia ma ka ili o kela a me keia paipu hao wiliwili, he zinc, i hanaia e ka hooluolu a me ka hooikaika ana o ka wai zinc e kahe ana ma ka paia o ka paipu ma hope o ka laweia'na o ka paipu kila mahe'e. ipu hao.

4. E hoʻohana kekahi poʻe kūʻai i ka pilina ma ke kaʻina hana o ka hoʻohana ʻana i ka paipu kila seamless galvanized e kaomi i ka groove. Ma muli o ka mānoanoa zinc papa o ka wela-hoi galvanized seamless kila paipu, ma lalo o ka hana o ka luku waho ikaika, hapa o ka galvanized papa e poha a peʻe aku, ka mea, aole i pili i ka maikai o ka galvanized seamless kila paipu iho. .

5. E pane ana kekahi mau mea kūʻai aku aia ka wai melemele ma ka paipu kila uʻi galvanized (kapa ʻia kēia wai i ka wai passivation), hiki ke passivate i ka ʻili metala. Hoʻohana maʻamau no ka mālama post-plating o galvanized, cadmium a me nā uhi ʻē aʻe. ʻO ke kumu o ka hana ʻana i kahi kūlana ili ma ka ʻili o ka uhi e hiki ke pale i ka hopena maʻamau o ka metala, hoʻomaikaʻi i kona kūpaʻa corrosion, a hoʻonui i ka aesthetics o ka huahana. Hiki iā ia ke hoʻomaikaʻi maikaʻi i ke kūpaʻa corrosion o ka paipu kila a hoʻolōʻihi i ke ola lawelawe o ka mea hana.

ʻOi aku ka maikaʻi o ka hopena pale o ka papa galvanized wela ma luna o ka paipu kila maʻemaʻe ma mua o ka pena a i ʻole ka papa plastik. I ke kaʻina hana o ka hoʻoheheʻe wela, hoʻoheheʻe ʻia ka zinc me ke kila e hana i kahi ʻāpana hui waena zinc-hao, ʻo ia hoʻi, kahi papa alloy. Ua hoʻopaʻa ʻia ka ʻāpana alloy i ke kila a me ka zinc, ʻoi aku ka ikaika ma mua o ka paʻa ma waena o ka pena a me ke kila. Hōʻike ʻia ka papa galvanized wela i ka lewa a ʻaʻole e hāʻule i nā makahiki a hiki i ka ʻino maoli ʻana.

ʻO ka ʻenehana galvanizing wela opaipu kila ʻoleHiki ke hoʻokaʻawale ʻia i ka dip plating a me ka blowing plating:

1. Hoʻopaʻa ʻia. E hooluolu me ka wai ma hope pono o ka hooluu ana. ʻOi aku ka mānoanoa o ka papa zinc ma mua o 70 microns, no laila ke kiʻekiʻe ke kumukūʻai o ka galvanizing, a nui ka nui o ka zinc. I loko o ka lewa maʻamau ma mua o 50 mau makahiki, aia nā hiʻohiʻona o ka kahe zinc, a hiki ke hoʻopaʻa ʻia ka paipu kila lōʻihi loa i 16m.

2. Puhi ka uhi. Ma hope o ka galvanizing, puhi ʻia ka ʻaoʻao o waho a maʻalili ʻia ka loko. ʻOi aku ka mānoanoa o ka papa zinc ma mua o 30 microns, haʻahaʻa ke kumukūʻai, a liʻiliʻi ka hoʻohana zinc. Ma hope o 20 mau makahiki o ka hoʻohana ʻana i ka lewa maʻamau, aneane ʻaʻole ʻike ʻia kahi ʻano o ka wai zinc. Laina hana zinc puhi nui 6-9m.
