Nā ʻano koho mea no nā pā metala

ʻO ke koho ʻana i nā ʻano mea no nā pā metala penei:

1. Kila kila: ʻO ia ka pōkole o ke kila kila kūpaʻa waikawa. He kūpaʻa ia i ka ea, ka mahu, ka wai a me nā mea ʻino ʻē aʻe a i ʻole he kila kila. Ma ke ʻano laulā, ʻoi aku ka paʻakikī o ke kila kila ma mua o ka alumini alloy, akā ʻoi aku ke kiʻekiʻe o ke kumukūʻai o ke kila kila ma mua o ka alumini alloy.

2. Pepa ʻōwili anu: He huahana i hana ʻia mai nā ʻōwili wela i ʻōwili ʻia ma ka mahana o ka lumi a ma lalo o ka mahana recrystallization. Hoʻohana ʻia i ka hana kaʻa, nā huahana uila, a pēlā aku.

ʻO ka papa kila ʻōwili anu ka pōkole o ka pepa kila kila kalapona maʻamau i ʻōwili anu ʻia, i ʻike ʻia hoʻi he pepa ʻōwili anu, i ʻike nui ʻia ʻo ka pepa ʻōwili anu, i kekahi manawa i kuhihewa ʻia ʻo ia he pepa ʻōwili anu. ʻO ka papa anu he papa kila me ka mānoanoa o lalo o 4 mm, i hana ʻia me nā ʻāpana kila kila kalapona maʻamau i ʻōwili wela ʻia a ʻōwili anu hou ʻia.

3. Papa alumini: ʻO ka papa alumini e pili ana i ka papa ʻehā i hana ʻia e nā ʻōpae alumini ʻōwili, i māhele ʻia i ka papa alumini maʻemaʻe, ka papa alumini alloy, ka papa alumini lahilahi, ka papa alumini mānoanoa waena, ka papa alumini i hoʻohālikelike ʻia, ka papa alumini maʻemaʻe kiʻekiʻe, ka papa alumini maʻemaʻe, ka papa alumini i hui pū ʻia, a pēlā aku.

4. Pepa galvanized: pili i kahi pepa kila i uhi ʻia me kahi papa zinc ma luna o ka ʻili. ʻO ke galvanizing kahi ʻano hana anti-rust waiwai a maikaʻi hoʻi i hoʻohana pinepine ʻia. Ma muli o nā ʻano lapaʻau like ʻole i ke kaʻina hana uhi, he ʻokoʻa nā kūlana ʻili o ka pepa galvanized, e like me ka spangle maʻamau, spangle maikaʻi, spangle pālahalaha, ʻili ʻole spangle a me ka phosphating, a pēlā aku. Hoʻohana nui ʻia nā huahana pepa galvanized a me nā huahana strip i ke kūkulu ʻana, ka ʻoihana māmā, ke kaʻa, ka mahiʻai, ka mahi holoholona, ​​ka lawaiʻa, ke kālepa a me nā ʻoihana ʻē aʻe.
