ʻO Anodizing kahi kaʻina hana i hoʻohanaʻia e hana i kahi kiʻiʻoniʻoni alumini oxide ma luna o ka papa o ka alumini a iʻole nā huahana alumini E pili ana i ka waihoʻana i ka Alumini a iʻole Alumini Alloy Foody e like me keʻano e pili ana i ka electrolyte e hana ai i ke kiʻi uila Alumil Ua hoʻomaikaʻiʻo Anodizing i ka paleʻana o ka corrosion, eʻaʻahu i ka paleʻana, a me nā waiwai hoʻonaninani o nā mea hana alumini I ka wā o ke kaʻina hana Anodinizing o nā poho alumini, hiki i kekahi mau hiʻohiʻona maʻamau ke hiki. E hoʻomaopopo pono iā mākou i nā kumu o nā hemahema. ʻO nā Crosteron, ka hoʻomahaʻana o ka lole,ʻaʻole i pau o Alloy lua, a iʻole nā hopena Galvaric hiki ke alakaʻi i nā hemahema. Ua weheweheʻia lākou penei:
1.ACID a Alkali etching
Ma mua o ke anadizing, e hoʻopiliʻia nā mea alumini a me nā wai alkaline, a iʻole e pili ana i nā'āpana a me nā alkaline i loko o ka wai keʻokeʻo. Inā he mea koʻikoʻi ka corrosion, hiki i nā wahi nui e hiki ke hana. He mea paʻakikī ke hoʻoholo i ka maka o nā maka a iʻole ka corrosion i kumu a iʻole alkali, akā hiki ke hoʻokaʻawaleʻia e ka'āpana o ka'āpana ma lalo o kahi microscope. Inā puni ka lua o ka lua a me kaʻole o ka corrosior inter or intergranur, i kumuʻia e Alkali etching. Inā kūlikeʻole ka lalo a me ka lalo a me ka mea paʻa, me nā pihi hohonu, ua kumu ia e ka etidching. ʻO ka mālama ponoʻana a me ka laweʻana i ka hale hana hiki ke alakaʻi i kēiaʻano o keʻano o ka corrosio. ʻO nā acid i nā mea e pili ana i nāʻoihana polish a iʻole nā mea hana acidic, a me nā mea e pili ana i nā helu crolrinated, nā kumuwaiwai o ka etching. ʻO Alkali etika - mea i lukuʻia e ka luluʻana a me ka puʻupuʻu o ka haku,ʻo ka lehu lehu, a me nā alkanane e holoi anaʻo Alkaline e holoi ana i nā wai wai. Ke hoʻoholoʻia ke kumu, hoʻoikaika i ka hoʻokeleʻana o nā kaʻina hana likeʻole i kaʻoihana i hiki ke hoʻopau i ka pilikia.
2.matMospo Corrosioni
Ua hōʻikeʻiaʻo Aluminim ʻAʻole maʻamauʻo ka corrosion ma keʻano he nui e like me ka acid a iʻole alkali etching a hiki ke hoʻopauʻia e nā hana likeʻole. ʻO ka corrosion inmosphec he nui loa a nānāʻoleʻia e hana i kekahi mau papa, e like me nā wahi haʻahaʻa haʻahaʻa a ma luna o nā papa wai. Ke paʻakikī nui neiʻo Atmospheric Corrosion Ma kēiaʻano,ʻaʻole hiki ke holoi nā holoi alkaliine lele e pio i ka pili o ka nui a me ka hoʻonuiʻiaʻana iā lākou. Inā hoʻoholoʻiaʻo ka corrosinic corrosionion, pono e nānāʻia nā kūlana mālama i ka hale hana. ʻAʻole pono e mālamaʻia nā lako alumini i nā wahi me nā haʻahaʻa haʻahaʻa haʻahaʻa e pale ai i ka laweʻana o ka wai. Pono e maloʻo ka wahi mālama, a pono e like me ke aniani e like me keʻano he hiki.
3.paper Corrosioni (nā wahi wai)
Ke kauʻia ka pepa a iʻole pepa paha ma waena o nā lako alumini a i hoʻohanaʻia no ka paleʻana, e pale i ka abrasition. Eia naʻe, inā lilo ka pepa i lilo i ka pepa, nā wahi o nā corrosioniona ma luna o ka'āpana o ka alumini. Ke hoʻohanaʻia nei nā kāleka corrugated, i nā laina maʻamau o nā'āpana corrosiona ma nā wahi e pili ana i nā wahi o ka hoʻopiliʻana me ka papa corrugated. ʻOiai eʻike ponoʻia nā hewa i kekahi manawa ma kaʻaoʻao alumini,ʻoi pinepine pinepine lākou ma hope o ka holoiʻana a me ka anodine. ʻO kēia mau wahi ākea ka hohonu a paʻakikī loa e wehe i ka mīkini a me ka holoiʻana a me ka holoiʻana. ʻO ka pepa (papa) i hoʻokumuʻia e ACIDE eCID, nui loa ia. No laila, hoʻohanaʻana i ka pepa (papa) me nā chlodes a me nā sulfes a me nā sulfes a me ka paleʻana i ka wai wai e pale ai i ka pepa (ka papa).
4.ʻO ka wai wai o ka wai (iʻikeʻia e like me ka hau
Ma hope o ka holoiʻana a Alkaline, ka lāʻau lapaʻau, a iʻole ka sulfuric acid pick, inā e loaʻa ana ka wai i ka lewa. ʻO ka hohonu hohonu o ka corrosinion. Ke hele nei kēiaʻano o ka corrosion i ka wā e nui loa ai ka wai hoʻomaʻemaʻe i ka nui a iʻole ka nui o ka holoʻana o ka holoʻana o ke kaheʻana E like me nā crystals snowflake-shapedflake ma keʻano, no laila ka inoa "i ka inoa" snowflaker corrosio. " ʻO ke kumu keʻano o ka hopena ma waena o nā mea nui o Zinc i ka alumini a me ka so42- a me CL- i ka wai hoʻomaʻemaʻe. Ināʻoi aku ka pōʻino o ka pahu o ka pahu, hiki ke hoʻonui i nā hopena galvanic e hoʻonui i kēia hemahema. Wahi a nā kumuwaiwai haole, i ka wā eʻoi aku ka nui o ka zn i ka alumini alloy ma mua o ka lōʻihi o keʻano o ka wai ma mua o 15 ppm. Me ka hoʻohanaʻana i ka nitric acid no kaʻohiʻana a hoʻohuiʻole 0.1% hno3 i ka wai hoʻomaʻemaʻe e hiki ai ke hoʻopau.
5. Kulaluna
ʻO ka heleʻana o kahi liʻiliʻi o ka chloride ma kaʻauʻau sulfuric acid aciving antizing e hiki ke alakaʻi i keʻano o ka hoʻopiliʻana. ʻO keʻano hiʻohiʻona he mau kīwī manu hohonu hohonu o nā hōkū ʻAʻoleʻo ka mea pili i nā'āpana me nā kiʻiʻoniʻoni he kiʻiʻoniʻoni, a me ka mānoanoa o ke kiʻi ma keʻano o ke koena "maʻamau" ma lalo o ka waiwai i manaʻoʻia. ʻO kaʻike paʻakai paʻakai i loko o ka wai waiʻo ia ke kumu nui o ke kumu o cl- i kaʻauʻauʻana i kaʻauʻau.
