He aha ka Zinc Phosphate Coatings

Manaʻo ʻia ʻo Zinc phosphate coating i ka hihia o ke koi ʻana o ke kūpaʻa corrosion kiʻekiʻe ma mua o ka hao phosphate. Hiki ke hoʻohana ʻia ma ke ʻano he kumu no nā kiʻi pena (ʻoi loa no ka thermosetting ka uhi lepo), ma mua o ke ki'i anu / hana anu o ke kila a me ka ho'ohana mua 'ana i ka aila pale / lubrication.
ʻO kēia ke ʻano i koho pinepine ʻia inā makemake ʻia ke ola lōʻihi ma lalo o nā kūlana corrosive. Maikaʻi nō hoʻi ka uhi ʻana me ka zinc phosphate no ka mea, ua hana nā kristal i kahi ʻili porous e hiki ke hoʻoheheʻe ʻia a hoʻopaʻa mechanical i ke kiʻi uhi. Ma ka ʻaoʻao ʻē aʻe, koi pinepine nā ʻōnaehana zinc phosphate i nā pae lapaʻau, ʻoi aku ka paʻakikī o ka mālama ʻana a ʻoi aku ka pipiʻi o ka hoʻouka ʻana a me ka hana. Hoʻokomo pinepine ʻia ke kiʻi zinc ma 200-500 milligrams i kēlā me kēia kapuaʻi square. ʻO ka nui o ka manawa e pono ai ma kahi o 4 mau minuke no kahi ʻōnaehana spray.
No ka uhi ʻana o ka zinc phosphate i lalo, ʻokoʻa ke kaumaha o ka uhi ʻana ma waena o 2 - 6 g/m². ʻAʻohe pono o nā mea paona kiʻekiʻe. Pono e ʻoi aku ke kiʻekiʻe o ka paona o ka zinc phosphate ma mua o ke kaha kiʻi anuanu / hoʻololi anuanu o ke kila, ʻokoʻa ia ma ka laulā o 5 - 15 g/m². No ka uhi ʻana i nā ʻāpana hao / kila e mālama ʻia me ka aila a i ʻole ka wax, ʻoi aku ka nui o ke kaumaha o ka uhi ʻana ma waena o 15 – 35 g/m².
