Koil Galvalume i pena mua ia

ʻO PPGL he kila galvalume i pena mua ʻia, i ʻike ʻia ʻo Aluzinc steel. Hoʻohana ka galvalume & aluzinc steel coil i ka pepa kila i ʻōwili ʻia ma ke ʻano he substrate a hoʻopaʻa ʻia e 55% aluminika, 43.4% zinc a me 1.6% silika ma 600 °C. Hoʻohui ia i ka pale kino a me ka lōʻihi kiʻekiʻe o ka alumini a me ka pale electrochemical o ka zinc. Ua kapa ʻia ʻo ia ka aluzinc steel coil.

Pōmaikaʻi:

ʻO ka pale ʻana i ka corrosion ikaika, 3 mau manawa o ka pepa kila galvanized.
ʻOi aku ka liʻiliʻi o ka 55% alumini ma mua o ka nui o ka zinc. Ke like ka paona a me ka mānoanoa o ka papa hoʻopalapala, ʻo ka ʻāpana o ka pā kila galvalume he 3% a i ʻole ka nui ma mua o ka ʻāpana kila galvanized.

Ua uhi ʻia ʻo Ppgi/ppgl (ke kila galvanized prepainted/prepainted galvalume steel) me ka papa organik, e hāʻawi ana i ka waiwai anti-corrosion kiʻekiʻe a me ke ola ʻoi aku ka lōʻihi ma mua o ka pepa kila galvanized.

ʻO ka metala kumu no ka ppgi/ppgl he kila ʻōwili anuanu, ke kila galvanized wela, ke kila electro-galvanized a loaʻa ke kila galvalume dip. ʻO ka mea i uhi ʻia e like me kēia: polyester, silicon modified polyester, polyvinylidene
fluoride, polyester kiʻekiʻe-durability, etc.
