ʻIke ʻoe i nā ʻano o nā paipu Galvanized?


Paipu kaulahao, i ʻike ʻia ʻo galvanized steel pipe, ua māhele ʻia i ʻelua ʻano: hot-dip galvanizing a me electro-galvanizing. Loaʻa i ka galvanizing Hot-dip kahi papa zinc mānoanoa a loaʻa iā ia nā mea maikaʻi o ka uhi ʻaʻahu, adhesion ikaika, a me ke ola lawelawe lōʻihi. He haʻahaʻa ke kumukūʻai o nā paipu electro-galvanized, ʻaʻole maʻalahi ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o nā paipu galvanized wela. I mea e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion o nā paipu kila, ua galvanized nā paipu kila maʻamau. Hoʻokaʻawale ʻia nā paipu kila galvanized i ʻelua ʻano: hot-dip galvanizing a me electro-galvanizing. He papa zinc mānoanoa ko ka galvanizing hot-dip. ʻO ka paipu hoʻoheheʻe ʻia o ka oxygen: hoʻohana ʻia ma ke ʻano he paipu no ka hana kila. ʻO ka maʻamau, hoʻohana ʻia nā paipu kila welded liʻiliʻi. No ka pale ʻana i ka corrosion, pono e hoʻomaʻamaʻa maikaʻi ʻia kekahi.

(1) Hana maʻemaʻe kūʻokoʻa
Hoʻohana ka paipu galvanized i ke kaʻina hana electroplating sulfate o ka zinc-iron alloy, ʻo ia ka mea aia nā perforations pololei ma waena o nā laina laina hana a me nā pā me ka ʻole o ka lawe ʻana a i ʻole ke kahe ʻana o ka hopena. ʻO kēlā me kēia kaʻina hana o ke kaʻina hana i haku ʻia me kahi ʻōnaehana circulation. ʻO nā haʻina i loko o kēlā me kēia pahu, ʻo ia hoʻi ka acid a me ka alkali solution, electroplating solution, light extraction and passivation solution, a me nā mea ʻē aʻe, ua hana hou ʻia a ʻaʻole i hoʻokuʻu ʻia ma waho o ka ʻōnaehana. ʻO ka laina hana wale nō he 5 mau pahu hoʻomaʻemaʻe, e hoʻohana ana i ke kahe. Hoʻohana hou a hoʻokuʻu pinepine ʻia, ʻoi aku hoʻi i nā kaʻina hana i hana ʻole i ka wai ʻino me ka hoʻomaʻemaʻe ʻole ma hope o ka passivation.
(2) ʻO ke ʻano o nā lako electroplating
ʻO ka electroplating o nā paipu galvanized a me ka electroplating o nā uea keleawe e like me ka electroplating hoʻomau, akā ʻokoʻa nā mea hana plating. Hoʻolālā ʻia ka pahu hoʻoheheʻe me ke ʻano ʻāpana lohi o ka uea hao. He lōʻihi ke kino pahu, ākea akā pāpaʻu. I ka wā o ka electroplating, hele nā ​​uea hao i loko o nā lua a hohola ma luna o ka ʻili wai ma kahi laina pololei, e mālama ana i ka mamao ma waena o lākou. Eia nō naʻe, ʻokoʻa ka paipu galvanized mai ka uea hao i kona mau hiʻohiʻona ponoʻī a ʻoi aku ka paʻakikī o ka pahu pahu. Hoʻokumu ʻia ke kino pahu i nā ʻāpana luna a lalo. ʻO ka ʻaoʻao o luna ka pahu pahu plating a ʻo ka ʻaoʻao haʻahaʻa ʻo ia ka pahu hoʻopaʻa ʻana i ka hoʻoheheʻe ʻana, e hana ana i kahi kino pahu e like me trapezoid i haiki ma luna a ākea ma lalo. Aia kahi ala no ka hana electroplating paipu galvanized i loko o ka pahu plating. ʻElua puka ma lalo o ka pahu e kamaʻilio me ka pahu waihona haʻahaʻa, a hoʻokumu i kahi ʻōnaehana hoʻoheheʻe paʻa me ka paila submersible. No laila, ua like nā paipu galvanized me ka hao uwea electroplating, a ʻo nā ʻāpana i hoʻopaʻa ʻia he ikaika. Eia nō naʻe, ʻaʻole like me ka hoʻopaʻa ʻana i ka uea hao, ʻoi aku ka ikaika o ka hopena plating no nā paipu galvanized.
(3) Optimization o ka sulfate galvanizing
ʻO nā mea maikaʻi o ka sulfate galvanizing ʻo ia ke kiʻekiʻe o ka pono o kēia manawa e like me 100% a wikiwiki ka helu deposition, ʻaʻole i hoʻohālikelike ʻia e nā kaʻina hana galvanizing ʻē aʻe. No ka maikaʻi ʻole o ka crystallization o ka uhi ʻana, ʻilihune ka hiki ke hoʻopuehu a me ka hiki ke hoʻopaʻa ʻia hohonu, no laila kūpono wale ia no ka hoʻopili ʻana i nā paipu a me nā uea me nā ʻano geometric maʻalahi. ʻO ke kaʻina hana zinc-iron alloy sulfate electroplating e hoʻomaikaʻi i ke kaʻina hana galvanizing maʻamau. Hoʻopaʻa wale ʻia ka paʻakai zinc sulfate, a hoʻolei ʻia nā mea i koe. Hoʻohui ʻia ka nui kūpono o ka paʻakai hao i ke kaʻina hana hou e hana ai i ka uhi ʻana o ka zinc-hao mai ka uhi metala hoʻokahi. ʻO ka hoʻonohonoho hou ʻana o ke kaʻina hana ʻaʻole ia e lawe i mua i nā pono o ka hana kiʻekiʻe o kēia manawa a me ka wikiwiki o ka deposition o ke kaʻina hana mua, akā hoʻomaikaʻi maikaʻi hoʻi i ka hiki ke hoʻopuehu a me ka hiki ke hoʻopaʻa hohonu. I ka wā ma mua, ʻaʻole hiki ke hoʻopaʻa ʻia nā ʻāpana paʻakikī, akā i kēia manawa hiki ke hoʻopaʻa ʻia nā ʻāpana maʻalahi a paʻakikī, a ʻo ka hana pale ʻana he 3 a 5 mau manawa kiʻekiʻe ma mua o ka metala hoʻokahi. Ua hōʻoia ka hana hana i ka wā i hoʻohana ʻia no ka hoʻomau mau ʻana o nā uea a me nā paipu, ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ka uhi ʻana ma mua o nā mea mua, a wikiwiki ka deposition rate. Hiki i ka mānoanoa o ka uhi ke koi i loko o 2 a 3 mau minuke.
(4) Ka hoʻololiʻana o ka sulfate zinc plating
ʻO ka paʻakai paʻakai o ka zinc-iron alloy wale nō ka paʻakai o ka zinc sulfate. Hiki ke hoʻohui ʻia nā mea ʻē aʻe e like me ka alumini sulfate, alum (potassium alumini sulfate), a pēlā aku i ka ʻauʻau plating i ka wā o ka mālama ʻana e hoʻohua i ka ua wai hydroxide insoluble. Wehe; no nā mea hoʻohui organik, hoʻohui i ka pauka i hoʻāla ʻia e wehe iā lākou ma ka adsorption.
Ua hōʻike ʻia nā hoʻāʻo ʻana e nā mea hana paipu galvanized he paʻakikī ka alumini sulfate a me ka potassium alumini sulfate e wehe loa i ka manawa hoʻokahi a loaʻa ka hopena i ka ʻōlinolino o ka uhi, akā ʻaʻole ia he koʻikoʻi a hiki ke lawe ʻia no ka ʻai. I kēia manawa, hiki ke hoʻihoʻi ʻia ka ʻōlinolino o ka uhi ma o ka mālama ʻana me ka hopena. E hoʻohui i ka mea i makemake ʻia e like me ke kaʻina hana hou e hoʻopau ai i ka hoʻololi.

Inā makemake ʻoe e ʻike i nā kikoʻī hou aku e pili ana i ka paipu kila galvanized, e ʻoluʻolu e kelepona mai iā mākou.

E leka uila iā mākou no ka ʻike hou aku
