ʻOi aku ka nui ma mua o 35m, a hiki i 200m ka papa wela wela, me ka uhi galvanizing wela maikaʻi, ka uhi paʻa a ʻaʻohe mea hoʻohui.E like me kā mākou e ʻike ai, ʻo ke ʻano o ke kūpaʻa corrosion o ka lewa o ka zinc e pili ana i ka pale mechanical a me ka pale electrochemical.Ma lalo o nā kūlana corrosion o ka lewa, aia nā kiʻiʻoniʻoni pale o ZnO, Zn (OH) 2 a me ka zinc carbonate kumu ma ka ʻili o ka papa zinc, e hoʻolohi i ka ʻino o ka zinc i kekahi ʻano.Inā pōʻino kēia kiʻiʻoniʻoni pale (ʻike ʻia ʻo ka ʻele keʻokeʻo), e hana ʻia kahi kiʻiʻoniʻoni hou
ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion o ka wai wela i ka hao hao kumu ma mua o ka galvanizing electro.
Hot dip galvanizing hale hana: ʻo ka mānoanoa o ka wela-hoʻopaʻa galvanized papa o ke kila mesh e hoʻoholo ai i ka hana anti-corrosion o ke kila mesh.Hiki i ka mea hoʻohana ke koho i ka mānoanoa o ka zinc coating i ʻoi aku ka kiʻekiʻe a i ʻole ka haʻahaʻa ma mua o ka maʻamau.No ka mīkini kila lahilahi me ka ʻili maʻemaʻe a me ka mānoanoa ma lalo o 3mm, paʻakikī i nā mea hana galvanizing wela ke loaʻa ka uhi mānoanoa i ka hana ʻoihana.Eia kekahi,ʻo ka mānoanoa o ka zinc coating i kūponoʻole me ka mānoanoa o ka mesh kila e hoʻopili i ka pili ma waena o ka uhi a me ka substrate a me keʻano o ka maikaʻi o ka uhi.ʻO ka nui o ka uhi ʻana e alakaʻi i ke ʻano ʻino, maʻalahi ka ʻili ʻana o ka uhi, a ʻaʻole hiki i ke kila kila ke kū i ka hui ʻana i ka wā o ka lawelawe ʻana a me ke kau ʻana.Inā ʻoi aku ka nui o nā mea hana e like me ke silikoni a me ka phosphorus i loko o nā mea maka o ke kila mesh, paʻakikī ke loaʻa i nā ʻāpana lahilahi i ka hana ʻoihana.ʻO kēia no ka mea e pili ana ka ʻike silika i loko o ke kila i ke ʻano ulu o ka papa alloy ma waena o ka zinc a me ka hao, ka mea e ulu wikiwiki ai ka pae zinc iron alloy layer a kū i mua o ka ʻili o ka uhi, e hopena i ka ʻeleʻele, Matt a me ka ikaika hoʻopaʻa maikaʻi ʻole. o ka uhi ana.
