ʻO ka puʻu hoʻoheheʻe wela wela ka mea e hoʻoheheʻe ai i ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi ʻāpana, i hui ʻia ka matrix a me ka uhi. ʻO ka galvanizing wela ka hoʻopili mua ʻana i ka paipu kila. I mea e wehe ai i ka hao oxide ma ka ʻili o ka paipu kila, ma hope o ka pickling, ua hoʻomaʻemaʻe ʻia i loko o ka pahu o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole i hui pū ʻia i ka wai o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i loko o ka. ʻauʻau wela. Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.

1. High puʻe kū'ē 'ana: wela-luu galvanized seamless paipu hiki ke ku i kiʻekiʻe kaomi.
2. Hiki ke mālama ʻia nā pena me ka adhesion awelika o 500g / m2 ma mua o 50 mau makahiki me ka mālama ʻole ʻia i nā wahi maloʻo a me nā kaona.

3. ʻAʻole pono ka mālama ʻana i ka wā e hoʻohana ʻia ai: ʻO nā paipu hoʻoheheʻe wela wela ke kū maikaʻi loa i ka wā a me ke ola lōʻihi o ka lawelawe ʻana, ʻaʻole koi i nā kumukūʻai mālama. Ke hoʻohālikelikeʻia me ka pena, pono ia i ka mālama mau, kahi e mālama ai i ka nui o ke kālā a me nā koina pilikanaka.
4. ʻO ke kūpaʻa maikaʻi, hiki ke kū i ka pōʻino mechanical mai ka lawelawe ʻana a me ka hāpai ʻana: ʻO ka papa galvanized he ʻano hoʻoheheʻe me ka paʻakikī maikaʻi loa a me nā waiwai mechanical.

5. Ke pale mau nei ka poino kūloko a i ʻole nā ​​kīnā liʻiliʻi: No ka mea, ʻoi aku ka ikaika o ka zinc ma mua o ka hao, hiki i nā kīnā liʻiliʻi ke pale i ke kila i ʻike ʻia, ʻo ia ka waiwai palekana o nā anodes mōhai.

6. Mālama piha, ʻaʻohe kihi make: ʻo nā hiʻohiʻona hana o ka puʻu puʻupuʻu wela wela e hoʻopiha piha i ka mea hana i loko o ka zinc wai, i hiki i kēlā me kēia kihi o ka mea hana ke hui pū kekahi me kekahi, ʻoi aku ka ʻoi a me ka ʻili concave. hiki ke mānoanoa i ka uhi ʻana, ʻo ia hoʻi kahi wahi i hiki ʻole ke hiki ke hoʻopaʻa ʻia.

7. ʻAʻole pili i nā ʻano mīkini o ka hoʻolālā kumu: ʻaʻohe hopena o ka galvanizing hot-dip i nā mea mechanical o ka seamless tube (SMLS).

ʻO ka ʻokoʻa ma waena o ka welagalvanizinga me ka galvanizing anu:

ʻO ka puʻupuʻu puʻupaʻa wela wela: hiki mai nā hopena kino a me ke kemika ma waena o ka paipu kila a me ka hoʻoheheʻe hoʻoheheʻe hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao me ka paʻa paʻa. Hoʻohui ʻia ka papa ʻaina me ka ʻāpana zinc maʻemaʻe a me ka substrate paipu kila. No laila, ua ikaika ka corrosion kū'ē.

ʻO ka puʻupuʻu liʻiliʻi galvanized anu: ʻO ka papa zinc he papa electroplating, a ua hoʻopaʻa kūʻokoʻa ʻia ka papa zinc me ka substrate paipu kila. He lahilahi ka papa zinc, a pili wale ka papa zinc i ka substrate paipu kila a maʻalahi ke hāʻule. No laila, ʻilihune kona pale ʻana i ka corrosion. I nā hale hou i kūkulu ʻia, pāpā ʻia ka hoʻohana ʻana i nā paipu kila galvanized anuanu e like me nā paipu wai.
