He aha ke ano o ka Phosphate coatings

ʻO nā uhi phosphate hoʻohana ʻia e hoʻonui i ka pale ʻana i ka corrosion a hoʻomaikaʻi pena kala adhesion, a hoʻohana ʻia ma nā ʻāpana kila no ka pale ʻana i ka corrosion, lubricity, a i ʻole he kumu no ka uhi ʻana a i ʻole ka pena pena. me ka ʻili o ka ʻāpana i uhi ʻia e hana i kahi papa o ka insoluble, crystalline phosphates. Hiki ke hoʻohana ʻia nā pale hoʻololi Phosphate ma ka alumini, zinc, cadmium, kālā a me ka tin.
ʻO nāʻano nui o ka phosphate coatings he manganese, ka hao a me ka zinc. Hoʻohanaʻia nā phosphates Manganese no ka paleʻana i ka corrosion a me ka lubricity a hoʻohana waleʻia e ka hoʻokomoʻana. Hoʻohana maʻamau ʻia nā phosphate hao ma ke ʻano he kumu no ka uhi hou ʻana a i ʻole ke pena ʻana a hoʻohana ʻia ma ka hoʻomaʻamaʻa ʻana a i ʻole ka pulupulu ʻana. Hoʻohana ʻia nā Zinc phosphates no ka hōʻoia ʻana i ka ʻōpala (P&O), kahi papa kumu lubricant, a ma ke ʻano he kumu pena/pena a hiki ke hoʻohana ʻia ma ka hoʻoinu ʻana a i ʻole ka pulupulu ʻana.
ʻO ka uhi phosphate he papa hoʻololi i ʻehikural mahalo. ʻOi aku ka liʻiliʻi ma mua o ka nui o nā metala akā ʻoi aku ka paʻakikī ma mua o nā uhi. Loaʻa iā ia nā waiwai hoʻonui wela i waena o ka metala a me ka uhi. ʻO ka hopena, hiki i nā papa phosphate ke hoʻomaʻemaʻe i nā loli hikiwawe o ka hoʻonui ʻana i ka wela i ʻole ma waena o ka metala a me ka pena. He porous ka uhi ʻana o ka Phosphate a hiki ke komo i ka uhi. Ma hope o ka ho'ōla ʻana, paʻa ka pena, paʻa i loko o nā pores phosphate. Hoʻonui nui ʻia ka adhesion.

KA HANA HANA PAPA PHOSPHATE

1. ʻO ka hoʻomaʻemaʻe hui ʻana a me ka phosphating. 1.0 a 1.5 mau minuke ma 100 degere F a 150 degere F.
2. Holoi wai no 1/2 mau minuke
3. Holoi wai ʻakika Chromic a i ʻole holoi wai deionized. 1/2 minuke.
