ʻO ka holoi ʻana ma hope o ka wehe ʻana i ka aila a me ka wehe ʻana i ka ʻōpala, ʻoiai aia ia i ke kaʻina hana kōkua ma mua o ka pena ʻana, pono nō hoʻi ia e hoʻokō pono.Ma hope o ka wehe ʻana o ka ʻaila a me ka ʻōpala, ʻoi aku ka maʻalahi o ka ili o ka workpiece e pili i kekahi mau surfactants non-ionic a me CL-.Inā ʻaʻole hoʻomaʻemaʻe maikaʻi ʻia kēia mau mea koena, hiki ke hana i ka phosphating film thinning, linear defects, a me ka phosphating.No laila, no ka hoʻomaikaʻi ʻana i ka maikaʻi o ka holoi ʻana i ka wai ma hope o ka wehe ʻana o ka aila a me ka hoʻopau ʻana i ka ʻōpala, pono ia e hele ma waena o nā holoi ʻana he nui, ʻelua holoi, manawa 1-2min, a hoʻololi pinepine i ka wai e hōʻoia i ka waiwai PH o ka wai ma waena o 5-7 .
Phosphating
ʻO ka mea i kapa ʻia he phosphating, e pili ana i ka mea hana metala ma hope o ka loaʻa ʻana o ka dihydrogen phosphate acid solution treatment, ka hopena kemika a ma kona ʻili e hoʻohua i kahi papa o ka phosphate film paʻa, ua kapa ʻia ke kiʻiʻoniʻoni phosphating.ʻO ke kumu nui o ka phosphating film e hoʻonui i ka adhesion o ka uhi a hoʻomaikaʻi i ke kūpaʻa corrosion o ka uhi.Nui nā ʻano o ka phosphating, e like me ka mahana o ka phosphating, hiki ke hoʻokaʻawale ʻia i ke kiʻekiʻe wela phosphating (90-98 ℃), ka mahana wela phosphating (60-75 ℃), haʻahaʻa wela phosphating (35-55 ℃) a me ka mahana maʻamau phosphating.
Ka hoʻopaʻapaʻa
Hoʻohana nui ʻia ka ʻenehana passivation o ka phosphating film ma ʻAmelika ʻĀkau a me nā ʻāina ʻEulopa.Hoʻokumu ʻia ka ʻenehana passivation i nā ʻano o ka phosphating film ponoʻī.He lahilahi ka phosphating film, maʻamau i ka 1-4G / m2, ʻaʻole ʻoi aku ka nui ma mua o 10g/m2, nui ka wahi pore manuahi, a ua kaupalena ʻia ke kūpaʻa corrosion o ke kiʻi ponoʻī.Kekahi a hiki i ka hoʻomaloʻo kaʻina hana ma ka wikiwiki melemele rust, ma hope o ka phosphating i ka passivation pani lapaʻau, hiki ke phosphating film pore hōʻike metala oxidation, a me ka hookumu ana o ka passivation papa, phosphating kiʻiʻoniʻoni hiki ke pāʻani i ka hoʻopiha, oxidation, hana phosphating film paʻa i loko o ka. lewa.
Ka maloʻo ʻana o ke kiʻiʻoniʻoni phosphating
ʻO ka hoʻomaloʻo ʻana i ke kiʻiʻoniʻoni phosphating hiki ke pāʻani i ʻelua mau kuleana, ma ka ʻaoʻao hoʻokahi, ʻo ia ka hoʻomākaukau ʻana no ke kaʻina hana aʻe e wehe i ka wai ma luna o ka ʻili o ke kiʻi phosphating, ma ka ʻaoʻao ʻē aʻe, ʻo ia ka hoʻomaikaʻi hou ʻana i ke kūpaʻa corrosion o ke kiʻi. ma hope o ka uhi ʻana.
No ka hoʻokumu ʻana i kahi laina pretreatment coating, pono e hoʻopau ʻia ka hoʻolālā kaʻina hana ma mua o ka hoʻolālā ʻana, ka hana ʻana a me ka hoʻokomo ʻana i nā mea hana maʻamau.No laila, ʻo ka hoʻolālā kaʻina hana ke kumu o ka laina hana, a ʻo ke ala pololei a kūpono e loaʻa ai ka hopena maikaʻi i ka hana hana a me ka maikaʻi o ka huahana.
Hoʻohana ʻia no nā ʻano pena kiʻi hana, hiki ke hoʻololi ʻia nā ʻano hoʻohālike ʻē aʻe.
