Manaʻo kumu: hoʻohana nui ʻia ka zinc alloys i loko o ka lumi ʻauʻau, nā ʻeke, nā kāmaʻa a me nā mea pono, no ka maʻalahi, ka plasticity, ke kumu kūʻai haʻahaʻa a me ka hana kiʻekiʻe.

Hoʻohana nui ʻia ʻo Zinc alloy i nā mea maʻemaʻe, nā ʻeke, nā kāmaʻa a me nā mea lole ma muli o kāna hana maʻalahi, ka plasticity ikaika, ke kumu kūʻai haʻahaʻa a me ka hana kiʻekiʻe.Eia nō naʻe, ʻo ka pilikia blistering o ka zinc alloy (electroplating; spraying) ua pilikia mau i nā hoa o nā hale hana lako a me nā hale hana electroplating.

Ua hōʻuluʻulu ʻia ka ʻike o ka zinc alloy foaming i nā hale hana electroplating o kekahi mau ʻoihana lako.

1. I ka hoʻomaka ʻana o ka hoʻolālā ʻana i nā huahana zinc alloy, pono mākou e noʻonoʻo i ka hoʻonohonoho ʻana o ke awa hānai, ke awa hoʻokuʻu slag a me ke awa exhaust o ka mold.Ma muli o ka maʻemaʻe o ke ala kahe o ka mea hana me ka hānai a me ka hoʻokuʻu ʻana i ka slag, ʻaʻohe ea entrapment, ʻaʻohe wai wai, ʻaʻohe ʻeleʻele ʻeleʻele, e pili pono ana inā e hū ana ka electroplating ma hope.ʻO ka mea hana me ka hānai kūpono a me ka hoʻolei ʻana i ka slag die casting he maʻemaʻe ka ʻili, ke kukui keʻokeʻo, ʻaʻohe wai wai.

2. I ka hoʻomohala ʻana i ka mold, pono mākou e noʻonoʻo i ka tonnage a me ke kaomi o ka mīkini kau ʻana.Ua ʻike mākou i kahi hanana blistering 20-30% ma hope o ka electroplating zinc alloy.ʻO kahi hale hana lako Friend ka hōʻike hoʻomāʻewaʻewa mua, a me 8 mau ʻāpana, a pehea e hoʻoponopono ai i ka pilikia o 20-30% ma mua o ka huʻa ʻana, a hoʻopaʻa hope i nā ʻāpana 4, a hoʻololi i 4 mau ʻāpana.

3. ʻAʻole i hoʻomaʻemaʻe ʻia ka hoʻonā calendering, polishing paste a me ka oxide layer ma ka ʻili o ka pretreatment, a ʻo ka ʻili o ka mea hana ma hope o ka calendering a me ka polishing he mālamalama.Nui nā limahana i ka pickling kaʻina o ka electroplating mea kanu pickling casually, ka hopena i ka ili pili calendering agent 'aʻole i hoʻomaʻemaʻeʻia, a me ka lōʻihi bubbles.Eia kekahi, aia kahi pilina nui ma waena o nā mea hoʻolalelale i koho ʻia e ka mea kanu calendering a me ka polishing, a ʻo nā surfactants i kekahi mau mea calendering e paʻakikī loa e holoi.

4. Ma mua o ka komo ʻana o ka huahana i loko o ka ʻauʻau ʻauʻau keleawe alkaline, aia nō ke kiʻi oxide (pickling film) ma ka ʻili o ka mea hana.ʻAʻole mālama pono ʻia ke kiʻi ʻoniʻoni hoʻoneʻe wax a me ka ʻaila.No laila, he mea nui e wehe i ke kiʻiʻoniʻoni.I nā makahiki mua, hiki ke wehe ʻia me ka paʻakai anti-staining.I kēia manawa, ʻaʻole ʻae ʻia ka hoʻokuʻu ʻana i ka wai ʻino me ka paʻakai anti-staining.Manaʻo ʻia e hoʻohana i ka pauka wehe kiʻi ʻoniʻoni lj-d009, ʻoi aku ka maikaʻi ma mua o ka paʻakai anti staining, hiki ke hoʻoneʻe i ka papa nickel, a hoʻokō ka hoʻokuʻu ʻana o COD i nā kūlana o ka honua.

5. He nui nā mea olaola a me nā haumia i loko o ka ʻauʻau keleawe keleawe alkaline, a ʻaʻole ka cyanide manuahi i ka laulā.E ho'āʻo i ke ʻano o ka pahu keleawe alkaline e ʻike inā he haʻahaʻa ka sodium cyanide a i ʻole ke kiʻekiʻe o ka sodium hydroxide!Inā hoʻohui pono ʻoe i ka mea hoʻomālamalama, ʻoi aku ka kiʻekiʻe o ka mālamalama, a he mea nui ka hoʻomaʻemaʻe ʻana i ka pahu keleawe alkaline.Manaʻo ʻia e hana ʻia ka mālama kalapona i hoʻokahi manawa i kēlā me kēia 3-5 mau lā

6. He mea nui loa ka conductivity o ke keleawe keleawe alkali.Inā hemo maʻamau ka anode a inā lawa ka pā keleawe anode e alakaʻi i ka pohū.

7. ʻO nā huahana Zinc alloy blister ke puka mai lākou mai ka umu;ma muli paha o ka wela ʻole o ka umu, ʻo ia hoʻi, ka wela kiʻekiʻe loa.No ka mea ʻaʻole paʻa ka hoʻoheheʻe make, maʻalahi ka hoʻokomo ʻana i ka waika i loko o nā ʻili wai a me nā trachomas o ka zinc alloy.ʻOiai inā loaʻa kahi ʻili o ka ʻili, e loaʻa i ka waika a me ka zinc ka hopena kemika, e hana ana i ka nui o ka hydrogen h.Ke kiʻekiʻe ke kaomi o ka ea i loko ma mua o ke kaomi o ka lewa i kekahi ʻano, a ʻo ka wela kiʻekiʻe e hoʻopuka i nā pua
