Kina hale hana maʻamau spangle galvanized kila coil gi dx51d
1. He aha ka wela wela galvanized coil.
ʻO ka galvanizing wela ka hana ʻana i ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi ʻāpana alloy, i hui ʻia ka matrix a me ka uhi.ʻO ka galvanizing wela ka hoʻopili mua ʻana i nā ʻāpana kila.I mea e wehe ai i ka hao oxide ma luna o ka ʻili o nā ʻāpana kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia i loko o kahi pahu o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka hopena aqueous hui ʻia o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i ka wela wela. pahu uhi.Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.
2. E like me ka ili no galvanized kila lau, aiaʻo ka spangle nui,spangle mau,mini(liʻiliʻi)spangle,zero spangle.
3. Pkaʻina hana hoʻoili:
Coil kila ʻōwili wela ——-decoiler—-entry accumulator—-annealing umu—– zinc pot—-cooling tower———air pahi——–chromating——exit accumulator—–coiler ——–galavanized steel coil
4. He aha nā pōmaikaʻi o ka wili kila galvanized?
No ka mea, hana ʻia ia ma o ka hoʻohana ʻana i ka lole Zn ma nā ʻaoʻao ʻelua ma ke kaʻina hana wela.
Mīkini.Hiki iā ia ke hoʻokō i nā koi kaʻina hana o ka rolling, Coiling a me nā kaʻina hana ʻē aʻe.
Ke pale wela: Ke hana maʻamau ka pā kila HDG ma lalo o 230℃, a ua loli kona kala ma 250℃, akā naʻe, hiki i ka pā kila galvanized ke hoʻomau i ke kaiapuni ma 315℃no ka manawa loihi.
ʻO ka manaʻo noʻonoʻo kiʻekiʻe: ʻO ka hiki ke noʻonoʻo o ka wela a me nā kukui ʻelua ʻoi aku ka nui ma mua o ka paʻi kila zinc hot-dip, a ʻoi aku ka nui o kona noʻonoʻo ʻana ma mua o 0.70, ʻo ia nā mea hana kūpono no ka mālama ʻana i ka ikehu.
Pūʻolo a me ka hoʻouna ʻana:
Hāʻawi i nā ʻano kaʻa like ʻole e pili ana i ka huakaʻi o ka mea kūʻai aku: ka lawe kaʻaahi a me ka lawe kai.I waena o lākou, ʻoi aku ka maʻamau o ka halihali moana.Load: He ʻokoʻa nā koi o kēlā me kēia hui moku, e like me nā koi o kēlā me kēia hui moku, mālama pono i nā lula, hoʻouka ʻana, hoʻoponopono i nā huahana.Mark: Hana a paʻi e like me nā koi o ka mea kūʻai aku.
