ʻO ka ʻike ʻana i ke kila kila electrogalvanized a me ka pahu kila wela wela

I ka wā ma mua, ʻo ka hoʻokaʻawale ʻana ma waena o ke kila electrogalvanized a me ka wela-dip galvanized steel grating i hilinaʻi nui ʻia i ka nānā ʻana i ka zinc spangles. ʻO Zinc spangles e pili ana i ke ʻano o nā hua i hoʻokumu ʻia ma hope o ka huki ʻia ʻana o ka pahu hao hao wela i waho o ka ipuhao hou a maloʻo a paʻa ka papa zinc. No laila, 'o ka ili o ka wela-luu galvanized kila grating mea maʻamau 'oʻoleʻa, me typical zinc spangles, oiai ka ili o electrogalvanized kila grating mea laumania. Eia nō naʻe, me ka hoʻomaikaʻi ʻana o nā ʻenehana hou, ʻaʻole i loaʻa hou nā hiʻohiʻona maʻamau o nā spangles zinc maʻamau. I kekahi manawa, ʻoi aku ka māmā o ka ili o ka weuweu puʻupuʻu kila a ʻoi aku ka noʻonoʻo ʻana ma mua o kēlā me ka electrogalvanized steel grating. I kekahi manawa, i ka wā e hoʻokomo pū ʻia ai kahi puʻupuʻu kila wela a me kahi puʻu kila electrogalvanized, he paʻakikī ke hoʻomaopopo ʻana ʻo ia ka mea wela wela a ʻo ia ka electrogalvanized steel grating. No laila, ʻaʻole hiki ke hoʻokaʻawale ʻia nā mea ʻelua ma ka helehelena i kēia manawa.

ʻAʻohe ala ʻike e hoʻokaʻawale i kēia mau ʻano galvanizing ʻelua ma Kina a i ʻole ma waena o ka honua, no laila pono e aʻo i ke ʻano o ka hoʻokaʻawale ʻana i nā mea ʻelua mai ke kumu kumu. E ʻike i ka ʻokoʻa ma waena o nā mea ʻelua mai ke kumu o ka galvanizing
, a e hoʻokaʻawale iā lākou mai ke alo a i ʻole ka loaʻa ʻole o ka papa aloi Zn-Fe ma ke ʻano. Ke hōʻoia ʻia, pono e pololei. ʻO ke kumu o ka galvanizing wela o nā huahana grating kila ka hoʻoinu ʻana i nā huahana kila ma hope o ka hoʻomaʻemaʻe ʻana a me ka hoʻōla ʻana i ka wai zinc hoʻoheheʻe ʻia, a ma o ka hopena a me ka hoʻopuehu ʻana ma waena o ka hao a me ka zinc, ua uhi ʻia kahi ʻāpana zinc alloy me ka adhesion maikaʻi ma luna o ka ʻili o nā huahana kila. ʻO ke kaʻina hana o ka papa galvanizing wela ke kaʻina hana o ka hana ʻana i ka hao-zinc alloy ma waena o ka matrix hao a me ka papa zinc maʻemaʻe o waho. ʻO kāna adhesion ikaika e hoʻoholo i kona kūpaʻa maikaʻi loa. Mai ka ʻano microscopic, ʻike ʻia ʻo ia ma ke ʻano he papa ʻelua.
ʻO ke kumu o ka electrogalvanizing o nā huahana grating kila, ʻo ia ka hoʻohana ʻana i ka electrolysis e hana i kahi ʻano like ʻole, paʻa, a paʻa maikaʻi i ka metala a i ʻole nā ​​​​mea hoʻoheheʻe ʻia ma ka ʻili o nā ʻāpana kila, a hana i kahi uhi ma ka ʻili o ke kila kila, i mea e hoʻokō ai i ke kaʻina hana o ka pale ʻana i ke kila kila mai ka ʻino. No laila, ʻo ka hoʻopili electro-galvanized kahi ʻano uhi e hoʻohana ai i ka neʻe kuhikuhi o ke au uila mai ka electrode maikaʻi i ka electrode maikaʻi ʻole. Zn2+ i loko o ka electrolyte nucleates, ulu a waiho ma luna o ke kila grating substrate ma lalo o ka hana o ka hiki ke hana i ka galvanized papa. Ma kēia kaʻina hana, ʻaʻohe kaʻina diffusion ma waena o ka zinc a me ka hao. Mai ka nānā ʻana i ka microscopic, ʻoiaʻiʻo he papa zinc maʻemaʻe.
ʻO ka mea nui, ʻo ka galvanizing hot-dip he papa hao-zinc alloy a me kahi papa zinc maʻemaʻe, aʻo ka electro-galvanizing he papa zinc maʻemaʻe wale nō. ʻO ka hele ʻana a i ʻole ka ʻole o kahi ʻāpana hao-zinc alloy i loko o ka uhi ʻana ke kumu nui no ka ʻike ʻana i ke ʻano o ka uhi ʻana. Hoʻohana nui ʻia ke ʻano metallographic a me ke ʻano XRD e ʻike ai i ka uhi e hoʻokaʻawale i ka electro-galvanizing mai ka hot-dip galvanizing.
