ʻAneʻane hana ʻia nā mea hoʻopaʻa a pau me ke kila kalapona a me ke kila kila, a manaʻo ʻia nā mea hoʻopaʻa maʻamau e pale i ka pala. Eia kekahi, pono e hoʻopili paʻa ka uhi ʻana o ka lāʻau lapaʻau.
No ka mālama ʻana i ka ʻili, hoʻolohe ka poʻe i ka nani a me ka pale ʻana i ka corrosion, akā ʻo ka hana nui o nā mea hoʻopaʻa ʻana ʻo ka hoʻopaʻa ʻana i ka pilina, a ʻo ka mālama ʻana i ka ʻili he mana nui hoʻi i ka hoʻopaʻa ʻana i ka hana o nā mea hoʻopili. No laila, i ke koho ʻana i ka mālama ʻana i ka ʻili, pono mākou e noʻonoʻo i ke kumu o ka hoʻopaʻa ʻana i ka hana, ʻo ia hoʻi, ke kūlike o ka torque hoʻonohonoho a me ka preload.
1. Electroplating
ʻO ka electroplating o nā mea paʻa, ʻo ia ka mea e hoʻoheheʻe ʻia ka ʻāpana o nā mea paʻa e hoʻopili ʻia i loko o kahi hoʻoheheʻe wai kikoʻī, e loaʻa ana kekahi mau pūhui metala i waiho ʻia, no laila, ma hope o ka hele ʻana i ka hopena wai me kēia manawa, e kahe a pili nā mea metala i loko o ka hopena. ka mahele o na mea paa. ʻO ka electroplating o nā mea hoʻopaʻa maʻamau ka galvanizing, keleawe, nickel, chromium, copper-nickel alloy, etc.
2. Phosphating
ʻOi aku ka maikaʻi o ka Phosphating ma mua o ka galvanizing, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka galvanizing. ʻElua mau ala phosphating maʻamau no nā mea hoʻopaʻa, zinc phosphating a me manganese phosphating. ʻOi aku ka waiwai lubricating o Zinc phosphating ma mua o ka manganese phosphating, a ʻoi aku ka maikaʻi o ka phosphating manganese i ka corrosion a ʻoi aku ka pale ʻana ma mua o ka zinc plating. ʻO nā huahana Phosphating e like me ka hoʻohui ʻana i nā bolts rod a me nā nati o nā ʻenekini, nā poʻo cylinder, nā bearings nui, nā bolts flywheel, nā bolts huila a me nā nati, etc.
3. Oxidation (ʻeleʻele)
ʻO ka ʻeleʻele+ʻaila kahi uhi kaulana no nā mea paʻa ʻoihana, no ka mea ʻoi aku ka liʻiliʻi a maikaʻi ke nānā aku ma mua o ka pau ʻana o ka pau ʻana o ka wahie. No ka mea, ʻaneʻane ʻaʻohe hiki i ka ʻeleʻele-ʻeleʻele, ʻeleʻele koke ia ma hope o ka ʻaila ʻole. ʻOiai i mua o ka aila, hiki i ka hoʻāʻo ʻana i ka paʻakai paʻakai kūʻokoʻa ke hiki i 3 ~ 5 mau hola.
4. Pumi wela zinc
ʻO ka galvanizing wela kahi uhi hoʻoheheʻe wela kahi e wela ai ka zinc i ka wai. ʻO 15 ~ 100μm kona mānoanoa o ka uhi, a ʻaʻole maʻalahi ka mālama ʻana, akā maikaʻi ke kūpaʻa corrosion, no laila hoʻohana pinepine ʻia i ka ʻenekinia. Ma muli o ka wela o ka hoʻoili zinc wela, (340-500C) ʻaʻole hiki ke hoʻohana ʻia no nā mea hoʻopaʻa ma luna o ka papa 10.9. ʻOi aku ka kiʻekiʻe o ke kumukūʻai o ka galvanizing hot-dip o nā mea hoʻopili ma mua o ka electroplating.
5. Zinc impregnation
ʻO ka Zinc impregnation kahi uhi hoʻoheheʻe wela metala o ka pauka zinc. He maikaʻi kona ʻano like ʻole, a hiki ke loaʻa nā ʻāpana i nā kaula a me nā puka makapō. ʻO ka mānoanoa o ka uhi ʻana he 10 ~ 110μm, a hiki ke hoʻomalu ʻia ka hewa i loko o 10%. ʻO kona ikaika paʻa a me ka hana anti-corrosion me ka substrate ka mea maikaʻi loa ma waena o nā uhi zinc (electro-galvanizing, hot-dip galvanizing a me dacromet). ʻO kāna kaʻina hana he pollution-free a ʻoi aku ka maikaʻi o ke kaiapuni. Inā ʻaʻole mākou e noʻonoʻo i ka chromium a me ka mālama ʻana i ke kaiapuni, ʻo ia ka mea kūpono loa no nā mea paʻa ikaika kiʻekiʻe me nā koi anti-corrosion kiʻekiʻe.
ʻO ke kumu nui o ka hoʻomaʻamaʻa ʻana i ka ʻili o nā mea paʻa, ʻo ia ka mea e loaʻa ai i nā mea hoʻopaʻa i ka mana anti-corrosion, i mea e hoʻonui ai i ka hilinaʻi a me ka adaptability o nā mea hoʻopili.
