Kaʻina electroplating o nā ʻāpana kaʻa

Hoʻokaʻawale kaʻina hana electroplating

1. Kaʻi ʻana

ʻO ka etching kahi ala e wehe ai i nā oxides a me nā huahana rust ma ka ʻili o nā ʻāpana me ka hoʻohana ʻana i ka hoʻoheheʻe ʻana a me ka etching o nā hopena waikawa. ʻO nā hiʻohiʻona o ke kaʻina hana etching kaʻa ʻo ia ka: wikiwiki ka wikiwiki o ka hana a nui ka nui o ka hui.

2. Ua hooheheeia

ʻO ka Zinc coating ka mea paʻa i ka lewa, loaʻa ka mana palekana hilinaʻi no ke kila a me ke kumu kūʻai haʻahaʻa. E like me kahi kaʻa kaʻa liʻiliʻi, ʻo ka ʻili o nā ʻāpana galvanized he 13-16m², ʻoi aku ma mua o 80% o ka nui o ka wahi plating.

3. Ke keleawe a me ka alumini electroplating

ʻO ka hoʻoheheʻe ʻia ʻana o nā huahana plastik e hele ana ma o ka hana kalai ʻana, ʻo ka ʻili o ka mea plastik e hoʻoheheʻe i nā pores microscopic, a laila e hoʻoheheʻe i ka alumini i ka ʻili.

Hoʻohana nui ʻia ke kila no nā kaʻa ma ke ʻano he kila hoʻonaninani kumu. ʻO ke aniani o waho he aniani, kiʻekiʻe kiʻekiʻe, kūpaʻa maikaʻi i ka corrosion, a hoʻohana nui ʻia no nā kaʻa kiʻekiʻe.
