Coil Ppgi Coated Galvanized Steel ASTM Color Zinc Coated Coil corrugated galvanized steel sheets

ʻO ka wehewehe pōkole:

ʻO ka coil i uhi ʻia ke kala he huahana ia o ka pā galvanized wela, alumini wela i hoʻopaʻa ʻia i ka zinc plate, electrogalvanized plate, a me nā mea ʻē aʻe, ma hope o ka hoʻomaʻamaʻa ʻana o ka ʻili (kemika degreasing a me ka hoʻololi ʻana i ke kemika), i uhi ʻia me hoʻokahi a i ʻole kekahi mau ʻāpana o ka uhi kūlohelohe ma ka ʻili, a laila kālua a hoʻōla ʻia. No ka mea, ua uhi ʻia me nā ʻano kala like ʻole o ka peʻa kala kala i kapa ʻia, i kapa ʻia ʻo coil coated color. Ma waho aʻe o ka pale ʻana o ka zinc layer, ʻo ka uhi kūlohelohe ma ka papa zinc e uhi a pale i ke kaula kila no ka pale ʻana i ka ʻōpala, a ʻo ke ola lawelawe ma kahi o 1.5 mau manawa ʻoi aku ka lōʻihi o ka galvanized strip. ʻO ke kala i uhi ʻia he māmā ke kaumaha, nani ke ʻano a me ke kūpaʻa corrosion maikaʻi, akā hiki ke hana pololei ʻia, ua māhele ʻia ke kala i ka hina, uliuli, ʻulaʻula ʻulaʻula, hoʻohana nui ʻia i ka hoʻolaha ʻana, ke kūkulu ʻana, ka ʻoihana ʻoihana home, nā ʻoihana uila, nā ʻoihana lako a me nā ʻoihana halihali.

ʻO ka pena i hoʻohana ʻia i ka nui o ka uhi kala e koho ʻia e like me ke ʻano hoʻohana like ʻole, e like me ka polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride a pēlā aku. Hiki i nā mea hoʻohana ke koho e like me ka hoʻohana.
