kiʻekiʻe anodizing mīkini semi auto alumini anodizing laina
①Aluminum profile surface lapaʻau:
ʻO ka mālama ʻana i ka ʻili o nā profiles aluminika, i ʻike ʻia ʻo ka pretreatment surface, ʻo ia ka hoʻohana ʻana i nā mea kino a me nā mea kemika e wehe i ka lepo ma luna o ka ʻili o nā profiles alumini, i ʻike ʻia ke kino profile alumini, kahi kūpono no ka hoʻomaʻamaʻa oxidation hope o ka alumini. ili pili.
②Aluminum profile surface degreasing kaʻina hana:
ʻO ke kumu o ke kaʻina hana degreasing no nā profiles aluminika e wehe i ka ʻaila lubricating ʻoihana a me ka ʻaila anti-corrosion ma luna o ka ʻili o nā profiles aluminika, a me ka lepo a me nā haumia e pili ana i ka ʻili o nā profiles, e hōʻoia i ka corrosion alkali o nā profiles aluminika, a e hōʻoia i ka maʻemaʻe o nā pahu etching alkali;a e hoʻomaikaʻi i ka maikaʻi o ka mālama ʻana i ka ʻili o nā profiles aluminika.
③ Aluminum profile acid etching kaʻina hana:
ʻO ke kaʻina hana etching acid ma luna o ka ʻili o nā profiles aluminika e hoʻokō i ka mālama ʻana i ka corrosion acid surface ma hope o ka degreasing ʻana i nā profiles alumini.ʻO ke kumu nui ka wehe ʻana i nā oxides i hana ʻia ma hope o ka hoʻoheheʻe ʻia ʻana o nā mea metala ʻē aʻe ma ka ʻili o nā profiles aluminika a me nā kiʻiʻoniʻoni oxide i hana maoli ʻia e nā profiles;pono ia ma hope koke o ka mālama ʻana i ka waika.E lawe i ka holoi wai, a e hoʻomalu ʻia ka mahana o ka holoi wai ma mua o 50 °C e pale i nā kaha kahe ma ka ʻili o ka ʻaoʻao, a laila hoʻomaʻemaʻe me ka wai kahe.No ka mea he ʻano keleawe ka ʻaoʻao alumini, lilo ka ʻili i ka pōʻeleʻele ma hope o ka hoʻoheheʻe ʻana i ka waikawa, a pono e hoʻoinu ʻia i loko o ka waika nitric solution no 3-5 mau minuke e hoʻomaʻamaʻa ai ka ʻili.
④Kaʻina etching alkaline o nā profile alumini:
ʻO ke kumu nui o ke kaʻina hana etching alkali o nā kiʻi alumini like ʻole me ke kaʻina hana etching acid, e wehe i nā koena mea a me nā papa metamorphic ma luna o ka ʻili o nā profiles alumini i ka wā o ke kaʻina oxidation, a e hoʻopau i nā hemahema i waiho ʻia ma ka ka ʻili o nā ʻaoʻao alumini i ka wā o ke kaʻina extrusion;He kuleana koʻikoʻi ka mālama ʻana o ka alkali etching i ka maikaʻi holoʻokoʻa o ka ʻili alumini.
⑤Aluminum profile neutralization kaʻina hana:
ʻO ke kumu o ke kaʻina hana neutralization profile aluminika, ʻo ia ka wehe ʻana i ke keleawe, manganese, hao, silicon a me nā mea hoʻoheheʻe ʻē aʻe a i ʻole nā mea haumia e waiho ʻia ma ka ʻili o ka ʻaoʻao alumini ma hope o ka etching acid a me ka hoʻomaʻamaʻa etching alkali, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hopena alkaline, a. hoʻokaʻawale i ka ʻaoʻao alumini.ʻO ka lye i koe ma hope o ka hoʻomaʻamaʻa ʻana i ka alkaline etching e hoʻohana mau ʻia e hoʻohana i kahi solution 30% -50% nitric acid.No nā alumini alumini silikona kiʻekiʻe, e hoʻolei ʻia i loko o nā ʻāpana, me ka hoʻohana ʻana i ka hui ʻana o ka waikawa nitric a me ka hydrogen fluoride i loko o ka ratio o ka 1:3 acid.Hoʻopili ʻo Silicon me ka hydrogen a me ka waika hydrofluoric e hana ai i ka waikawa fluorosilicic a waiho i ka ʻili alumini.
⑥Anodizing ka mālama ʻana i nā ʻaoʻao alumini:
ʻO ke ʻano o ka anodizing i ka ʻaoʻao alumini ka hoʻohana ʻana i ka hopena ma ke ʻano he medium, a hoʻohana i ka hoʻokuʻu ʻana e hana i kahi kiʻiʻoniʻoni oxide ma luna o ka ʻili o ka ʻaoʻao alumini, i loaʻa i ka ʻaoʻao alumini ke kūpaʻa ʻoi loa, ma muli o ka pae pale i loaʻa. e ka anodized alumini profile He kiʻekiʻe ka paʻakikī a me ka pale ʻana i ka corrosion, a ʻo ka mānoanoa maʻamau ʻo 10-12μ, hiki ke hoʻomaikaʻi maikaʻi i ka pale ʻana o ka oxidation o nā profiles alumini a hoʻomaikaʻi i ka aesthetics o nā profiles.
Hoʻohana maʻamau ka anodization sulfuric acid i ka 10-20% H2SO4 e like me ka electrolyte, ʻo ka mahana hana he 15-20 ℃, ʻo ka nui o kēia manawa he 1-2.5A / dm2, a ʻo ka manawa electrolysis e pili ana i nā koi mānoanoa kiʻi, maʻamau 20-60min.ʻO ke kumu mana maʻamau ʻo ke au pololei.ʻOkoʻa ka volta i hoʻohana ʻia ma muli o ka conductivity, ka mahana a me ka ʻike alumini o ka electrolyte.ʻO ka maʻamau, ʻo ia ka 15-20V.He hopena koʻikoʻi nā ʻāpana kaʻina hana i ka hana o ka membrane.
⑦ Aluminum profile surface sealing treatment:
Ma hope o ka anodized o ka profile alumini, e hoʻokumu ʻia nā micropores ma luna o ka ʻili, kahi maʻalahi ke hoʻoheheʻe ʻia a hoʻopaʻa ʻia i ka wā hoʻohana.Pono e hana ʻia ka hoʻopaʻa ʻana ma hope o ka mālama anodizing.ʻO ke kaʻina hana puka mai ʻEulopa), sulfuric acid anodizing maʻamau e hoʻohana i ka 10-20% H2SO4 e like me ka electrolyte, ʻo ka mahana hana ʻo 15-20 ℃, ʻo ka nui o kēia manawa he 1-2.5A / dm2, ʻo ka manawa electrolysis e pili ana i ka mānoanoa kiʻiʻoniʻoni. pono, maʻamau i loko o 20-60min.ʻO ke kumu mana maʻamau ʻo ke au pololei.ʻOkoʻa ka volta i hoʻohana ʻia ma muli o ka conductivity, ka mahana a me ka ʻike alumini o ka electrolyte.ʻO ka maʻamau, ʻo ia ka 15-20V.He hopena koʻikoʻi nā ʻāpana kaʻina hana i ka hana o ka membrane.
