Kila kohu ʻole
ʻO ia ka pōkole o ke kila kila kūpaʻa waikawa. Wahi a GB/T20878-2007, ua wehewehe ʻia ʻo ia he kila me ke kūpaʻa kila a me ka palaho ma ke ʻano he mau ʻano nui, me ka nui o ka chromium ma ka liʻiliʻi he 10.5% a me ka nui o ke kalapona ʻaʻole iʻoi aku ma mua o 1.2%. 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 kumukūʻai o ke kila kila ma mua o ka alumini alloy.
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.
Pepa galvanized
ʻO ke ʻano o ka galvanizing he ʻano hana anti-rust waiwai a maikaʻi hoʻi i hoʻohana pinepine ʻia. Ma muli o nā ʻano hana like ʻole i ke kaʻina hana uhi ʻana, he ʻokoʻa nā kūlana ʻili o ka pepa galvanized, e like me ka spangle maʻamau, ka spangle maikaʻi, ka spangle pālahalaha, ka ʻili ʻole 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.
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 me nā mea ʻē aʻe. ʻO ka papa alumini e pili ana i ka mea alumini me ka mānoanoa o 0.2mm a i ʻole 500mm, ka laulā o 200mm, a me ka lōʻihi o 16m.
