Kaʻina hana lapaʻau ʻili o nā kī kaʻa

Ke kaʻina hana lapaʻau ili owili huilaʻO ka mea maʻamau e komo i kēia mau mea:

1.Galvanizing: E ​​hoʻokomo i ka ʻili o ka bolt i loko o kahi solution zinc a hana i kahi papa pale o ka zinc ma ka ʻili o ka bolt ma o nā hopena electrochemical.Hiki i kēia kaʻina hana lapaʻau ke hoʻomaikaʻi i ke kūpaʻa corrosion o nā bolts a hoʻonui i ko lākou ola lawelawe.

2.Hoʻomaʻamaʻa wela: E hoʻomaikaʻi i nā waiwai mechanical o nā bolts ma ka hoʻomehana ʻana iā lākou i kahi mahana a laila hoʻomaʻalili wikiwiki iā lākou.ʻO nā ʻano hana lapaʻau maʻamau e pili ana i ka quenching, tempering, etc., hiki ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī o nā bolts.

3.Rust pale lapaʻau: E hoʻohana i ka rust inhibitors a me ka uhi e pale aku i ka ili owili huilamai ka oxidation a me ka corrosion.ʻO nā ʻano hana pale maʻamau e pili ana i ka pīpī ʻana i ka pena anti rust, ka hoʻopili ʻana i nā pale anti-corrosion, etc.

4.Electroplating: E ​​hoʻokomo i ka pōleʻa i loko o kahi electrolyte e hana i ka hopena electrochemical o nā ion metala ma waena o ka anode a me ka cathode, e hoʻokomo i nā ion metala ma luna o ka ʻili o ka bolt, e hana i kahi kiʻi metala me ka pale ʻana i ka corrosion, ka ʻōlinolino, a me ka nani.

5.Dacromet: E kau i nā ʻāpana bolt i hoʻohauʻoli ʻia e ka wai i loko o kahi ʻauʻau i loaʻa ka hopena Dacromet no ka hoʻopaʻa ʻana.ʻO ka hopena Dacromet kahi hopena hoʻoheheʻe inorganic i loaʻa ka zinc, aluminika, a me ka chromium.
