Nui ka leo galvanized uea galvanizing mea prone i ka pilikia

Aia nā ʻāpana paʻa i loko o ka hoʻonā paʻa.Inā ʻoʻoleʻa ka lihi a me ka piko o nā ʻāpana, ʻoi aku paha ka nui o ka nui o kēia manawa.Ina kapapa galvanizedmaikaʻi, akā i ka 3% nitric acid māmā, he malu ʻeleʻele ka uhi, ʻike ʻia ke kiʻiʻoniʻoni passivation ʻeleʻele, hiki ke galvanized wai keleawe a i ʻole ke alakaʻi a me nā mea metala ʻē aʻe.E nānā mua i ka mahana a me ka nui o kēia manawa, a laila ma o ka ʻauʻau ʻauʻau, e hoʻoholo a hoʻoponopono i ka ʻike o ka zinc a me ka sodium hydroxide i loko o ka ʻauʻau, he haʻahaʻa ka DPE, hiki ke hoʻomaopopo ʻia ma o ka hoʻāʻo ʻana o ka pahu pahu.

Inā ʻaʻole ʻo ka uhi ʻana i nā kumu i luna, hiki ke kumu ʻia e ka haumia i ka hopena plating, hiki ke lawe i kahi mea liʻiliʻi o ka plating solution, a kānana ma hope o ka hoʻokolohua, a laila lawe i kahi liʻiliʻi o ka plating solution, hoʻokolohua i ka pauka zinc i hana ʻia. , E nānā inā ʻaʻole paʻa nā ʻāpana paʻa a i ʻole keleawe, ke kēpau, a me nā mea haumia ʻē aʻe ʻē aʻe, kēlā me kēia mea, hoʻāʻo, ʻaʻole paʻakikī ke ʻimi i ke kumu o ka hāʻule.ʻO ka wehe ʻole ʻana o ka ʻaila a i ʻole ka ʻakika waika ke kumuuea hao nuiʻōhū uhi.

Akā, ʻo ke kumu nui o kēia ʻano ʻauʻau e maʻalahi i ka huʻi ʻana, ʻo ia ka adsorption o nā mea hoʻohui organik ma ka ʻili aniani o ka uhi, i hiki ʻole ai i ke aniani kumu a i ʻole kekahi ʻili aniani ke ulu maʻamau, e hopena i ka ulu ʻana o ka nuclei kristal hou. a i ʻole kekahi ʻili aniani;A i ʻole nā ​​mea hoʻohui kūlohelohe i loko o ka clip uhi, keakea i ka hoʻonohonoho maʻamau o ka lattice, ka hopena i ka distortion lattice, a laila e hoʻonui ai i ke koʻikoʻi o loko o ka uhi ʻana, ka hopena o ka uhi ʻana.
