ʻO ka paʻi Zinc ka mea maʻamau, koho ʻāpana liʻiliʻi. ʻO ka galvanizing wela ka mea maʻamau, koho ola lōʻihi.
2. He aha ka Zinc Plated?
ʻO Zinc Plating he electrodeposited zinc coating hoʻohana ʻia i ke kila a i ʻole ka hao ma o ka hana electrochemical.
ʻO kāna kumu kumu, ʻo ia ka hana ʻana i kahi papa zinc pale e pale i ka metala kumu mai ka ʻino.
Ma ka hana ʻenekinia, hoohana nui ia ma ʻāpana liʻiliʻi a liʻiliʻi e like me na mea paa, Nā wilipū, punawai, nā brackets, a me ka lako lako, ʻoi aku ka nui o ka pololei ʻana a me ka mana kūpono.
ʻO ke kumu hana maʻalahi akā maikaʻi loa: ʻo ka uhi ʻana o ka zinc ma ke ʻano he papa ʻālana.
Ke ʻike ʻia ka ʻāpana i ka wai, oxycongen, a i ʻole nā kūlana corrosive ʻē aʻe, ʻānai mua ka zinc a pale i ke kila o lalo.
No ka mea, hoʻohana ʻia ka uhi ʻana ma kahi haʻahaʻa haʻahaʻa, Mālama ʻo zinc plating i ke ʻano kumu o ka ʻāpana a pale i ka distortion i hiki ke loaʻa i nā kaʻina hana uhi kiʻekiʻe..
Nā hiʻohiʻona o ka Zinc Plated Materials
Hoʻohālikelike ʻia nā ʻāpana i hoʻopaʻa ʻia i ka zinc e a kope, keʻaʻahuʻia, a ʻili maʻalahi, a maikaʻi ka paʻa ʻana.
Hoʻohālikelike ʻia me nā mea hoʻoheheʻe zinc-based, Hoʻopili ka zinc plating i kahi palena palena wale nō o ka mānoanoa,
He mea kūpono ia no nā ʻāpana kikoʻī kahi e hoʻopilikia ai ke kūkulu nui ʻana i nā kaula, kūpono, a i ʻole nā mea hoʻoneʻe.
ʻO ka hopena maʻamau ʻeleʻele hina a ʻeleʻele paha, ʻoiai hiki ke loaʻa nā hiʻohiʻona ʻoi aku ka maikaʻi ma o ka hoʻokele kaʻina hana a ma hope o ka mālama ʻana.
Ma ka hana pono, Hiki i nā ʻenekini ke koho i nā papa mānoanoa o ka uhi ʻana e like me ke ʻano lawelawe a me ka geometry.
Hoʻolilo kēia i ka zinc plating i kahi koho maʻalahi no nā ʻāpana e pono ai ka pale me ka ʻole e kaumaha ana i ka pololei.
ʻO kekahi pōmaikaʻi koʻikoʻi ʻo ia ka hiki ke hoʻohui ʻia ke kaʻina hana ka hoʻopaʻa ʻana a i ʻole ka hoʻopaʻa ʻana, hiki ke hoʻomaikaʻi i ka helehelena a hoʻonui i ka pale ʻana i ka corrosion ma nā wahi haʻahaʻa.

I kēia mau hihia, ʻO ka waiwai nui o ka zinc plating ka hiki ke hāʻawi kope, pale ʻana i ka corrosion ʻoiai e mālama ana i ka ʻāpana me ka pololei a me ka hoʻokele waiwai.
3. He aha ka Galvanized?
Ma ka hana ʻenekinia, i hooheheeia pili pinepine kila hoʻopaʻa wela: ka hao a i ʻole ke kila i hoʻoheheʻe ʻia i loko o ka zinc hoʻoheheʻe ʻia e hana i kahi uhi pale.
Hoʻopili ʻo ASTM A123/A123M i nā uhi zinc galvanized wela ma luna o ka hao a me nā huahana kila., me nā huahana i hana ʻia a i hana ʻole ʻia,
