Ua kapa ʻia ʻo Galvalume steel coils he aluzinc coils / Zincalum coils / galvanized alumini coils.Aia ia me 55% aluminika, 43.4% zinc a me 1.6% silika i ho'ōla ʻia ma 600 ℃. Ke hana nei i kahi aniani quaternary nui, no laila e hana i kahi pale ikaika a maikaʻi e pale ai i ke komo ʻana o nā kumu ʻino.
Nā hiʻohiʻona huahana
▶ Pale ʻino maikaʻi loa.ʻO ke ola lawelawe o ka galvalume he 3-6 mau manawa e like me ka lōʻihi o ka galvanized surface.I ka wā o ka hoʻāʻo ʻana i ka paʻakai ma mua me ka galvalume a me ka galvanized i like ka mānoanoa o ka uhi.
▶ Ka Hana Hana Pono.Hoʻopiha piha i ke koi o ka hana ʻōwili, stamping, bending, ect.
▶ Hoʻomaʻamaʻa māmā maikaʻi loa.ʻO ka hiki ke hoʻohālikelike i ka mālamalama a me ka wela he ʻelua i ka galvanizing. A ʻoi aku ka nui o ka reflectivity ma mua o 0.7.No laila, hoʻohana pinepine ʻia e like me nā mea insulation.
▶ Pale wela maikaʻi loa.Hiki ke hoʻohana ʻia nā huahana Galvalume ma 315 degere Celsius no ka manawa lōʻihi me ka ʻole o ka wehe ʻana.ʻOiai nā huahana galvanized discolor ma 250 degere Celsius.
▶ Hoʻopili maikaʻi ma waena o ka pena.He maʻalahi ke pena a hiki ke pena ʻia me ka ʻole o ka hoʻomaʻamaʻa mua ʻana a me ka wā.
