Anti-corrosion o galvanized kila paipu kuʻihao: Ma hope o ka mālama ʻana i ka ʻili, wela ka zinc. Inā ʻaʻole hiki ke galvanizing ma ka pūnaewele, hiki iā ʻoe ke hahai i ke ʻano anti-corrosion ma ka pūnaewele: brush epoxy zinc-rich primer, epoxy micaceous iron intermediate pena, a me ka polyurethane topcoat. ʻO ka mānoanoa e pili ana i nā kūlana kūpono.

Nā hiʻohiʻona o ke kaʻina paipu kila galvanized
1. ʻO ka maikaʻi o ka sulfate galvanizing: ʻO ka 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 kūlike me 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 nā paipu electroplating 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 sulfate maʻamau, mālama wale i ka paʻakai zinc sulfate nui, a hoʻolei i nā mea ʻē aʻe. Ma ke kaʻina hana hou, ua hoʻohui ʻia ka nui kūpono o ka paʻakai hao e hana i kahi uhi hao zinc-hao mai ka uhi metala hoʻokahi. ʻO ka hoʻonohonoho hou ʻana o ke kaʻina hana ʻaʻole wale e hoʻolaha i nā pono o ke kaʻina kumu o ka hana kiʻekiʻe o kēia manawa a me ka wikiwiki deposition wikiwiki akā hoʻomaikaʻi maikaʻi hoʻi i ka hiki ke hoʻopuehu a me ka mana plating 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 hōʻike ʻia ka hana hana ʻana i ka hoʻomau ʻana o ka electroplating o nā uea a me nā paipu i ʻoi aku ka maikaʻi a me ka ʻoi aku ka maikaʻi o ka uhi ʻana i nā huaʻai 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.

2. Ka hoololi ana o ka sulfate zinc plating: Sulfate electroplating o ka zinc-iron alloy wale nō ka paʻakai paʻakai zinc sulfate o ka sulfate zinc plating, a me nā mea i koe e like me ka alumini sulfate a me ka alum (potassium alumina sulfate) hiki ke hoʻohui me ka sodium hydroxide i ka wā o ka. ka hoʻoponopono ʻana i ka hoʻoheheʻe ʻana no ka hoʻoulu ʻana i ka wai hydroxide insoluble no ka wehe ʻana; no nā mea hoʻohui organik, hoʻohui ʻia ke kalapona hoʻōla pauka no ka adsorption a me ka wehe ʻana. Hōʻike ka hōʻike i ka paʻakikī o ka alumini sulfate a me ka potassium alumini sulfate e hoʻopau loa i ka manawa hoʻokahi, he hopena ia i ka mālamalama o ka uhi, akā ʻaʻole ia he koʻikoʻi a hiki ke hoʻopau ʻia me ka wehe ʻana. I kēia manawa, hiki ke hoʻihoʻi ʻia ka mālamalama o ka uhi. Hiki ke hoʻohui ʻia ka hopena e like me ka ʻike o nā mea i koi ʻia e ka hana hou ma hope o ka mālama ʻana, a ua pau ka hoʻololi ʻana.

3. ʻO ka wikiwiki o ka waihoʻana a me ka hana palekana maikaʻi loa: ʻO ka maikaʻi o kēia manawa o ka sulfate electroplating zinc-iron alloy ka mea kiʻekiʻe e like me 100%, a ʻaʻole i hoʻohālikelike ʻia ka wikiwiki deposition wikiwiki e kekahi kaʻina galvanizing. ʻO ka holo wikiwiki o ka paipu maikaʻi he 8-12m / min, a ʻo ka mānoanoa o ka uhi ʻana he 2m / min, he paʻakikī ke hoʻokō me ka hoʻomau galvanizing. ʻO ka uhi ʻana he ʻulaʻula, palupalu, a ʻoluʻolu i ka maka. E like me ke ʻano o ka pae aupuni GB / T10125 "Artificial Atmosphere Test-Salt Spray Test", ua paʻa ka uhi ʻana a ʻaʻole i hoʻololi ʻia no nā hola 72; ʻike ʻia kahi ʻōpala keʻokeʻo liʻiliʻi ma ka ʻili o ka uhi ma hope o 96 mau hola.

4. Hana maʻemaʻe kūʻokoʻa: Hoʻohana ka paipu kila galvanized i ke kaʻina hana zinc-iron alloy sulfate electroplating, ʻo ia hoʻi, ua hoʻopili pololei ʻia nā laina laina hana a ʻaʻole i lawe ʻia ka hopena. ʻO kēlā me kēia kaʻina hana o ke kaʻina hana i loko o kahi ʻōnaehana circulation. ʻO nā haʻina o kēlā me kēia pahu, ʻo ia hoʻi ka acid a me ka alkali solution, electroplating solution, a me ka light and passivation solution, e hana hou ʻia a hoʻohana hou ʻia me ka ʻole o ka leakage a i ʻole ka hoʻokuʻu ʻana i waho o ka ʻōnaehana. ʻO ka laina hana he 5 mau pahu hoʻomaʻemaʻe wale nō, i hana hou ʻia a hoʻohana pinepine ʻia, ʻoi aku hoʻi i ke kaʻina hana me ka hana ʻole ʻana o ka wai ma hope o ka passivation.

5. ʻO ke ʻano o nā mea hana electroplating: ʻO ka electroplating o nā paipu kila galvanized e like me ka electroplating o nā uea keleawe, ʻo ia hoʻi nā electroplating mau, akā ʻokoʻa nā mea hana plating. ʻO ka pahu paʻi i hoʻolālā ʻia no nā hiʻohiʻona lohi o ka uea hao he lōʻihi a ākea akā pāpaʻu. I ka wā electroplating, hele ka uea hao i loko o ka lua a hohola ma luna o ka ʻili wai ma kahi laina pololei, e mālama ana i kahi mamao mai kekahi i kekahi. Eia naʻe, ʻokoʻa nā paipu kila galvanized mai nā uwea hao a loaʻa iā lākou nā hiʻohiʻona kūʻokoʻa. ʻOi aku ka paʻakikī o nā lako pahu. Hoʻokumu ʻia ke kino pahu i nā ʻāpana luna a lalo. ʻO ka ʻaoʻao o luna ka pahu plating, a ʻo ka ʻaoʻao haʻahaʻa ʻo ia ka pahu hoʻopaʻa ʻana i ka hoʻoheheʻe ʻana, e hana ana i kahi kino pahu trapezoidal i haiki ma luna a ākea ma lalo. Aia kahi ala no ka electroplating o nā paipu kila galvanized i loko o ka pahu plating. ʻElua mau puka ma lalo o ka pahu i hoʻopili ʻia i ka pahu mālama ma lalo, a hana i kahi ʻōnaehana hoʻonā plating a hoʻohana hou i ka ʻōnaehana me ka paila submersible. No laila, ʻoi aku ka ikaika o ka hoʻopili ʻana o nā paipu kila galvanized, e like me ka electroplating o nā uea hao. ʻAʻole like me ka electroplating o nā uea hao, ʻo ka hopena plating o nā paipu kila galvanized electroplated.
