He aha nā kaʻina hana lapaʻau maʻamau?

1. Kapu ana: E pale i ka ʻili ma ke kāpī ʻana i ka pena a i ʻole ka pauka i mea e pale ai i ka ʻino, hāʻawi i kahi uhi paʻa, a hoʻololi i nā kala he nui e like me nā pono. Hoʻohana maʻamau i nā kākoʻo hale kila, e like menā papa hoʻohui eleeka, alakaʻi i nā pūpū kāmaʻa, nā pale kila kihi, nā hale lako mīkini, etc.

2. Electroplating: ʻO nā mea maʻamau ka galvanizing, chrome plating a me ka nickel plating, kūpono loa no nā pale metala, e like me nā pale kila kila,nā pale kākoʻo kila kihi, etc. ʻO nā hiʻohiʻona o ka galvanizing ka pale ʻana i ka ʻōpala, ʻoiai nā hiʻohiʻona o ka chrome plating a me ka nickel plating e hoʻonui ʻia i ka ʻili a me ke kūpaʻa.

3. Anodizing: Hoʻohana pinepine ʻia kēia ʻano hana no nā pale pale alumini. Hoʻopuka ia i kahi papa oxide ma ka ʻili alumini ma o ka mālama ʻana i ka electrochemical, hoʻonui i ka antioxidant a me ka pale ʻana i nā huahana alumini, a hiki ke kala ʻia.

4. Electrophoretic uhi: He kūpono no nā pale me nā ʻano paʻakikī, hiki i ka ʻenehana electrophoretic ke uhi pono i ka pena ma ka ʻili metala, me nā kihi āpau ʻaʻole hiki i ka ʻoihana maʻamau ke hiki. ʻO ka pōmaikaʻi o ka electrophoresis ʻo ia ka pale ʻana i ka ʻōpala maikaʻi loa a me ke kūpaʻa ʻana.

5. Lapaʻau Phosphate: hoʻohana nui ʻia no ka hoʻomaʻamaʻa mua ʻana ma mua o ka pena ʻana, ʻoi aku hoʻi no nā pale kila, kahi e hoʻokumu ai i kahi kumu ʻoi aku ka maikaʻi no ka pena ʻana a i ʻole ka hoʻoulu ʻana, hoʻonui i ka adhesion o ka uhi a hāʻawi i ka hana anti-rust.

ʻO ke koho ʻana o kēia mau ʻano hana lapaʻau e pili ana i nā mea e like me nā mea waiwai, hoʻohana i ka ʻāina, ke kumukūʻai a me nā pono o ka mea kūʻai aku.
