He aha ka electroplating?
ʻO ka electroplating ke kaʻina hana o ka hoʻohana ʻana i ke kumu o ka electrolysis e waiho i kahi ʻāpana lahilahi o nā metala ʻē aʻe a i ʻole nā mea hoʻoheheʻe ʻia ma luna o kekahi mau mea metala. He kaʻina hana ia e hoʻohana ai i ka electrolysis e hoʻopili i kahi kiʻiʻoniʻoni metala i ka ʻili o ka metala a i ʻole nā mea waiwai ʻē aʻe, no laila e pale ai i ka hoʻoheheʻe metala (e like me ka ʻōpala), hoʻomaikaʻi i ka pale ʻana i ka lole, conductivity, reflectivity, corrosion resistance (e like me ka copper sulfate), a hoʻonui i ka nani.
Hoʻokaʻawale hou ʻia ka Electroplating i nā kaʻina kikoʻī e like me ka hoʻoheheʻe keleawe, ka uhi gula, ka plating kālā, ka chromium plating, ka nickel plating, a me ka zinc plating. I ka ʻoihana hana, hoʻohana nui ʻia ka zinc plating, nickel plating, a me ka chromium plating. He aha ka ʻokoʻa ma waena o kēia mau mea ʻekolu?
01- Hoʻoulu ʻia
Wehewehe: ʻO ka hoʻoheheʻe Zinc e pili ana i kahi ʻenehana lapaʻau ʻili e pili ana i ka uhi ʻana i kahi papa zinc ma ka ʻili o kahi metala, hao, a i ʻole nā mea ʻē aʻe no nā kumu hoʻonaninani a me ka pale ʻana.
Nā hiʻohiʻona: ʻO ke kumu kūʻai haʻahaʻa, ke kūpaʻa corrosion maʻamau, ke kala keʻokeʻo kālā.
Noi: Screws, circuit breakers, industry products, etc.
02- Ka hoʻopaʻa ʻana i ka nikela
Wehewehe: ʻO ke ʻano o ka hoʻopaʻa ʻana i kahi papa nickel ma luna o kahi metala a i ʻole kekahi mau metala ʻole ma o ka electrolysis a i ʻole nā hana kemika i kapa ʻia ʻo nickel plating.
Nā hiʻohiʻona: Nani, hiki ke hoʻohana ʻia no ka hoʻonaninani, ke kumu kūʻai kiʻekiʻe, ka hana paʻakikī liʻiliʻi, a ʻo ke kala ke kala keʻokeʻo a melemele.
Noi: ʻO nā mea paʻa kukui mālama ikehu, nā ʻāpana, nā ʻāpana lako, etc.
03- Hoʻopili Chromium
Wehewehe: ʻO Chromium he metala keʻokeʻo keʻokeʻo me ka waihoʻoluʻu polū liʻiliʻi. ʻO ke ʻano o ka hoʻopaʻa ʻana i kahi papa o ka chromium ma luna o kahi metala a i ʻole kekahi mau metala ʻole ma o ka electrolysis a i ʻole nā ʻano kemika i kapa ʻia ʻo chromium plating.
Nā hiʻohiʻona: ʻElua ʻano o ka chrome plating. ʻO ka mea mua no nā mea hoʻonani, me kahi hiʻohiʻona nani a me ke kūpaʻa maikaʻi. ʻAʻole maikaʻi kona hiki ke pale i ka ʻōpala e like me ka zinc plating, akā ʻoi aku ka maikaʻi ma mua o ka oxidation; ʻO ke ala ʻelua ka hoʻonui ʻana i ka paʻakikī a me ke kūpaʻa ʻana o nā ʻāpana metala, ʻo ia ka hana o nā ʻāpana.
Hoʻohana: ʻO nā ʻāpana hoʻonani nani, nā mea hana, nā kīʻaha, a me nā mea ʻē aʻe ma nā mea pono hale, nā mea uila a me nā huahana ʻē aʻe.
E hoʻonui i ka ʻike:
1. Hoʻokumu nui ʻia ka hana electroplating ma muli o ka hoʻohaumia ʻana i nā metala koʻikoʻi i loko o ka wai a me ka wai. Ua kāohi koʻikoʻi ka ʻāina i ka hoʻonui ʻana i ka ʻoihana electroplating a ua hoʻemi ʻia i kēlā me kēia makahiki.
Ma Kina, pili ka hana electroplating i ka galvanization, copper plating, nickel plating, a me chromium plating, me ka galvanization accounting no 50% a me ka copper plating, chromium plating, a me ka nickel plating accounting no 30%.
Inā ʻo ke kumu o ka pale ʻana i ka ʻōpala, hiki ke hoʻohana ʻia ka galvanizing a cadmium plating; Inā pili ka nānā ʻana i ka pale ʻana i ka lole, ʻo ka nickel a i ʻole ka chromium plating ke koho maikaʻi loa.
