ʻO ka paipu Galvanized he paipu kila me kahi uhi wela a i ʻole electroplated ma kona ʻili.Hiki i ka Galvanizing ke hoʻonui i ka pale ʻana o nā paipu kila a hoʻonui i ko lākou ola lawelawe.Hōʻike kēia ʻatikala i nā ʻano hana o nā paipu galvanized:
1. Hoʻonui i ka Sulfate Zinc Plating
ʻO ka pōmaikaʻi nui loa o ka sulfate zinc plating ʻo ia ka pono o kēia manawa a hiki i ka 100% a me ka wikiwiki deposition rate, ʻaʻole i hoʻohālikelike ʻia e nā kaʻina hana zinc plating.Ma muli o ka lawa ʻole o ka crystallinity o ka uhi, ka hoʻopuehu maikaʻi ʻole a me ka hiki ke hoʻopili hohonu, kūpono wale ia no ka electroplating o nā paipu a me nā uea me nā ʻano geometric maʻalahi.Hoʻonui ʻia ke kaʻina hana hoʻoheheʻe zinc sulfate maʻamau e ke kaʻina hana hoʻoheheʻe zinc sulfate.Hoʻopaʻa wale ʻia ka paʻakai nui Zinc sulfate, a hoʻolei ʻia nā mea ʻē aʻe.E hoʻohui i ka nui kūpono o ka paʻakai hao i ke kaʻina hana hou e hana ai i kahi uhi hao zinc mai ka uhi metala hoʻokahi.ʻO ka hoʻoponopono hou ʻana o ke kaʻina hana ʻaʻole wale e hoʻolaha i nā pono o ka hana kiʻekiʻe o kēia manawa a me ka wikiwiki o ka deposition wikiwiki o ke kaʻina hana mua, 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 hoʻopili ʻia nā ʻāpana maʻalahi a paʻakikī, a hoʻomaikaʻi ʻia ka hana pale e 3-5 mau manawa i hoʻohālikelike ʻia me nā metala hoʻokahi.Ua hōʻoia ka hana hana no ka hoʻomau electroplating o nā uea a me nā paipu, ʻoi aku ka maikaʻi o ka nui o ka uhi ʻana, ʻoi aku ka māmā, a ʻoi aku ka wikiwiki o ka deposition ma mua o ka wā ma mua.Hoʻokō ka mānoanoa o ka uhi i nā koi i loko o 2-3 mau minuke.
2. Ka hoohuli ana o ka Sulfate Zinc Plating
ʻO Zinc sulfate wale nō, ka paʻakai koʻikoʻi o ka sulfate zinc plating, i hoʻopaʻa ʻia no ka sulfate electro galvanized iron alloy.Hiki ke hoʻoneʻe ʻia nā mea ʻē aʻe e like me ka Aluminum sulfate a me ka alum (Potassium alum) ma o ka hoʻohui ʻana i ka sodium hydroxide e hana i ka wai wai wai hiki ʻole ke hoʻoheheʻe ʻia i ka wā o ka mālama ʻana i ka solution plating;No nā mea hoʻohui organik, hoʻohui ʻia ka pauka i hoʻāla ʻia no ka adsorption a me ka wehe ʻana.Hōʻike ka hōʻike he mea paʻakikī ke hoʻopau loa i ka Aluminum sulfate a me ka alum Potassium i ka manawa hoʻokahi, kahi hopena i ka mālamalama o ka uhi, akā ʻaʻole ia he koʻikoʻi, a hiki ke hoʻopau ʻia me ia.I kēia manawa, hiki ke hoʻihoʻi ʻia ka ʻōlinolino o ka uhi ʻana i ka hopena ma o ka mālama ʻana, a hiki ke hoʻopau ʻia ka hoʻololi ʻana ma ka hoʻohui ʻana i nā mea i koi ʻia e ka hana hou.
3. ʻO ka wikiwiki deposition wikiwiki a me ka hana pale maikaʻi loa
ʻO ka hana kūpono o kēia manawa o ka sulfate electroplating zinc iron alloy kaʻina he kiʻekiʻe e like me 100%, a ʻaʻole like ka helu deposition i kekahi kaʻina galvanizing.ʻO ka wikiwiki hana o ka paipu maikaʻi ʻo 8-12 m / min, a ʻo ka mānoanoa o ka uhi ʻana he 2 m / min, he paʻakikī ke hoʻokō i ka hoʻomau galvanizing.ʻO ka uhi ʻana he ʻulaʻula, palupalu, a ʻoluʻolu i ka maka.Hoʻāʻo ʻia e like me ke ʻano maʻamau GB / T10125 "Artificial Atmosphere Test - Salt Spray Test", 72 mau hola, paʻa a hoʻololi ʻole ka uhi;Ma hope o 96 mau hola, ʻike ʻia kahi ʻōpala keʻokeʻo liʻiliʻi ma ka ʻili o ka uhi.
4. Hana maʻemaʻe kū hoʻokahi
Hoʻohana ka paipu galvanized i ke kaʻina hana galvanized galvanized iron alloy sulfate electroplating, kahi i hōʻike ʻia e ka perforation ma waena o ka laina laina hana a me ka slot, me ka ʻole o ka hoʻonā ʻana a i ʻole ke kahe ʻana.ʻO kēlā me kēia kaʻina hana i loko o ke kaʻina hana i loaʻa i kahi ʻōnaehana circulating.ʻO nā haʻina i loko o kēlā me kēia pahu, me ka acid-base solution, electroplating solution, discharge 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 wale nō he 5 mau pahu hoʻomaʻemaʻe, i hoʻokuʻu mau ʻia ma o ka hoʻohana hou ʻana, ʻoi aku hoʻi i ke kaʻina hana kahi ʻaʻohe wai ʻino i hana ʻia ma hope o ka passivation me ka hoʻomaʻemaʻe ʻole.
5. Ka particularity o electroplating lako
ʻO ka electroplating o nā paipu galvanized, e like me ka electroplating o ka uea, no ka electroplating mau, akā ʻokoʻa nā mea hana no ka electroplating.ʻO kahi ʻāwī paʻa i hoʻolālā ʻia no ka uea hao me kona mau hiʻohiʻona ʻōniʻoniʻo, lōʻihi a ākea ke kino o ke aʻe akā pāpaʻu.I ka wā o ka electroplating, puka ka uea hao mai ka lua ma ke ʻano laina pololei
