Pono nā mea hoʻopaʻa i ka Surface Treatment? Pehea e hana ai?

ʻO nā mea paʻa he ʻano ʻāpana mechanical i hoʻohana nui ʻia no ka hoʻopaʻa ʻana i nā pilina. Hiki ke ʻike ʻia nā mea hoʻopaʻa like ʻole ma nā mīkini like ʻole, nā lako, nā kaʻa, nā moku, nā alahao, nā alahaka, nā hale, nā hale, nā mea hana, nā mea kani, nā mea hana a me nā lako.
ʻO nā mea hoʻopaʻa ma kahi kokoke i nāʻoihana a pau i hanaʻia i ke kila kalapona a me ke kila kila. Manaʻo kekahi mau ʻano mea paʻa e pale i ka ʻino. ʻOiai ke hoʻohana ʻia nā mea hoʻopaʻa me nā mea anticorrosive, pono mau ka mālama ʻana i ka ʻili kūpono e pale i ka corrosion o nā mea like ʻole.

ʻO Zinc Plating
Hiki ke hoʻopaʻa ʻia nā mea hao hao me ka zinc no ke kūpaʻa ʻana i ka corrosion maikaʻi aʻe a hiki i ka mānoanoa o 200 – 300 micro inches (.0002" - .0003"). ʻO nā mea paʻa i hoʻopaʻa ʻia i ka zinc he hopena kala ʻālohilohi. He hoʻopau mōhai ia ma ka hana ʻana i kahi "galvanic cell" corrodes ma mua o ke kila kumu. ʻO nā mea paʻa i hoʻopaʻa ʻia i ka Zinc he kūpaʻa kūʻokoʻa akā ʻeleʻele i ka manawa a ʻoi aku ka wikiwiki inā ʻino ka uhi a i ʻole ke ʻike ʻia i nā mea ʻino (e laʻa i nā kaiapuni kai). ʻAʻole i ʻoi aku ma mua o 12 mau hola o ka pale ʻana i ka paʻakai o ka paʻi ʻana o kēia ʻano. ʻO ke kūpaʻa ʻino o ka zinc e pili ana i ka mānoanoa o ka uhi a hiki ke hoʻonui hou ʻia ma ka hoʻohana ʻana i kahi uhi hoʻololi. Hāʻawi ka zinc hoʻopau i kekahi waiwai esthetic, hoʻonui i ka pale ʻana i ka abrasion a hāʻawi i kahi papa hoʻopaʻa maikaʻi loa no ka pena.
Phosphate ʻeleʻele
ʻO ka Phosphating ka mea i kapa ʻia ʻo Parkerization, he kaʻina hoʻololi phosphate hoʻololi ʻia kahi e hoʻoneʻe ʻia ai kahi papa microscopic hao a hoʻololi ʻia me kahi ʻāpana lahilahi like ʻole o ka zinc a i ʻole manganese dioxide e hoʻolilo i ka substrate kila i ʻoi aku ka ʻino a me ke kūpaʻa. ʻO ka hopena hope loa he uʻi a paʻa i ka hina-ʻeleʻele. ʻAʻole hiki ke kaʻina Parkerizing me nā metala non-ferrous e like me ke aluminika, keleawe, a me ke keleawe. ʻAʻole hiki ke hoʻohana ʻia i nā kila i loaʻa ka nui o ka nickel, a i ʻole ma ke kila kila. Hoʻohana pinepine ʻia ka uhi phosphate ʻeleʻele e hoʻoikaika i ka pale ʻana i ka corrosion. Eia naʻe, ʻaʻole hāʻawi ka phosphate coating iā ia iho i ka pale ma muli o ke ʻano porous o ka uhi.
No laila, hoʻohana ʻia ka lāʻau lapaʻau hou me ka ʻaila a i ʻole nā ​​​​mea sila ʻē aʻe no ka loaʻa ʻana o kahi pae haʻahaʻa o ka pale ʻana i ka corrosion.
ʻO nā uhi phosphate hoʻohana maʻamau e kōkua i ka uhaʻi ʻana i nā mea e komo ai a kōkua i ka pale ʻana i ka maʻi ʻeha. Hoʻohana ʻia ia no ka hoʻomākaukau ʻana i nā wahi no ka uhi ʻana a/a i ʻole ke pena. ʻO ke ʻano porous o ka hoʻopau phosphate e hiki ai i nā mea ke komo i loko o ka uhi e hāʻawi ai i kahi kumu adhesion maikaʻi loa no nā lapaʻau lua. Eia kekahi, ʻo ke ʻano kemika o ka uhi e hoʻokaʻawale i ka ʻili o ka ʻāpana e hōʻemi ana i ka corrosion e ulu mai ana ma ka metala a me ka pena.
ʻO Cadmium
Hoʻopili Cadmium hāʻawi maikaʻi i ka pale ʻana i ka corrosion ʻoiai ma nā wahi paʻakikī (e laʻa me nā lewa paʻakai). Hāʻawi ia i kahi kumu pena maikaʻi ma muli o nā waiwai adhesion pena maikaʻi loa, a ʻoi aku ke kūpaʻa i ka wehe ʻana ma mua o ka plating zinc.
He maikaʻi nō hoʻi ʻo Cadmium no ka hoʻopaʻa ʻana i ke kila kila, a me ka alumini e pale ai i ka ʻino galvanic. He keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo ʻo Cadmium ma ke ʻano. Hiki i ka mālama hou ʻana ke hoʻohua i kahi ʻano iridescent, ʻeleʻele, gula, amber a ʻoliva a hoʻonui i ka pale ʻana i ka corrosion.
ikona
Hoʻohana ʻia ʻo Chrome i ka hoʻopaʻa ʻana i nā mea hoʻopaʻa maʻamau no nā kumu esthetics. Hāʻawi ia i ke kūpaʻa corrosion e like me ka zinc plating, akā ma ke kumukūʻai ʻoi aku ka kiʻekiʻe. Inā ʻoi aku ka nui o ke kūpaʻa ʻana i ka corrosion e koi ʻia i ke kila kila, hiki ke hoʻopaʻa ʻia i ka chrome, e pale ana i ka ʻino inā e pōʻino ka chrome.
Nahu Pahu
Ma muli o ke kaʻina hana i hoʻohana ʻia a me ka noi i manaʻo ʻia, hiki ke waiho ʻia ka nickel me ka palupalu a paʻakikī paha, ʻulaʻula a ʻālohilohi paha. Hoʻohana pinepine ʻia ka Nickel plating no ka hoʻopau hoʻonaninani. ʻO ka hoʻoheheʻe ʻana i ka nickel alohilohi kahi hoʻopau hoʻohālikelike e like me ke kila kila, akā paʻakikī loa me ka ductility maikaʻi ʻole. No laila, pono e hana ʻia nā ʻāpana i ke ʻano hope ma mua o ka uhi ʻia ʻana me ka nickel mālamalama. ʻOi aku ka satiny hoʻopau ma mua o ka nickel māmā, a ʻoi aku ka ductile.
Pono e uhi ʻia me ka nickel palupalu nā mea i hoʻoweliweli ʻia i ka wela a i ʻole ka piko liʻiliʻi i mea e hōʻemi ai i ka ʻili ʻana a i ʻole ka ʻili.
Hoʻohana nui ʻia ka Nickel plating ma nā mea hoʻopaʻa i nā wahi e pono ai ka pale corrosion a me ka conductivity maikaʻi.
Hawaʻi-wela
ʻO ka galvanizing hot-dip o nā mea hoʻopaʻa he mea hoʻopaʻa kila kalapona i ka wela o kahi kokoke i 510 ° c hoʻoheheʻe i ka pahu zinc plated i mea e hoʻopaʻa ai i ka ili o Fe-Zn alloy i loko o ka passivation o ka zinc, ka hopena i ka mālama ʻana. ʻOi aku ka kiʻekiʻe o nā mea paʻa o ke kumu kūʻai galvanized wela ma mua o ka electroplating.
ʻO Dcromet
ʻAʻohe pilikia hoʻoheheʻe hydrogen. Me ka noʻonoʻo ʻole i ka pale ʻana i ke kaiapuni o ka hexavalent chromium, kūpono maoli ia no nā mea paʻa ikaika kiʻekiʻe me nā koi anticorrosion kiʻekiʻe.
ʻO nā mea hoʻopaʻa, ʻo ia kekahi o nā huahana me ka nui o ka lawe ʻana a me ka hoʻokuʻu ʻana i Kina, he koʻikoʻi kūpono a hoʻolālā e hoʻolaha i nā ʻoihana Kina e komo i ka honua a hoʻolaha i ko lākou komo piha ʻana i ka hui honua a me ka hoʻokūkū.
