ʻO ka hui kemika o ka mea hoʻololi rust "Tsinkar"
Nā mea
He aha ka hana ʻana o Zinkar?
ʻO ka hui kemika o Tsinkar he mea palekana ia no nā kānaka, akā i ka manawa like me nā mea ikaika e kū pono ana i nā kikowaena o ka luku metala. Hoʻokumu ʻia ia ma ka phosphoric acid i hoʻomaʻemaʻe ʻia me ka hoʻohana ʻana i nā ʻenehana kūikawā a hoʻoheheʻe ʻia me ka wai, kahi i hoʻohui ʻia ai nā pūhui zinc a me manganese.
ʻO kahi hiʻohiʻona koʻikoʻi o ka mea hoʻololi ʻo Zinkar ʻo ia ka hoʻohui ʻana o ka hopena i loko o ka manganese a me ka zinc i loko o kahi kūlana reactive, kahi e hana ai i kahi kiʻi pale o ka ikaika kūikawā ma ka ʻili metala. Ua hōʻike nā kānaka ʻepekema ʻo ia nā mea kemika ikaika o ka lāʻau lapaʻau, e hana ana i nā pālua, e hiki ai ke hoʻokō i ka pono kiʻekiʻe o Tsinkar - ma kahi o 2-2,7 mau manawa kiʻekiʻe ma mua o ka monophosphate solutions, ʻoi aku ka nui ma ka mākeke a ʻo lākou. ʻoi aku ka maikaʻi, akā ʻaʻole kūpono ka mālama ʻana.
Pehea e hana ai nā mea hana i ka mea hoʻololi rust Zinkar?
ʻO ka hana nui o ka zinc he hopena pololei i nā kikowaena o ka corrosion electrochemical, ka hana ʻana i kahi pale metala pale. Aia kona manaʻo i ka ʻoiaʻiʻo ma lalo o ka mana o ka ea e haki ka mea pale, e hōʻoia ana i ka palekana o nā mea metala ma lalo o ia.
Me ke kōkua o ka manganese, ua hoʻopili ʻia ka ʻili i mālama ʻia, ʻo ia hoʻi, ua hoʻomaikaʻi ʻia nā ʻano o ka papa pale, kahi e hoʻokaʻawale ai iā Zincar mai nā pūhui monophosphate.
Hiki i ka waikawa Orthophosphoric ke hiki i ka zinc a me ka manganese ke hōʻike iā lākou iho i ke ala maikaʻi loa. ʻO ke ʻano o kāna hana ʻo ka hoʻokumu ʻana i kahi papa pale i ke ʻano o kahi kiʻiʻoniʻoni phosphate, kahi e hoʻomaikaʻi nui ai i ka adhesion, ʻo ia hoʻi, ka hoʻopili ʻana o ka ʻili metala a me nā mea pena i hoʻopili ʻia iā ia. Inā pōʻino ka pena a me ka phosphate, pau ka ulu ʻana o nā kikowaena corrosion i loko o nā palena o ka wahi i uhaki ʻia ka pono o ka papa. I ka manawa like, hoʻemi ʻia ka hopena o ka waikawa phosphoric ma ka pālākiō a me nā oxides non-hydrated.
Eia kekahi, aia ka hopena o Zinkar i ka tannin, a me ka adsorption a me ka passivating inhibitors. Pono ka mea mua no ka hoʻololi ʻana i ka hao hao i loko o nā pūhui e hiki ai i nā ʻāpana ʻōpala ke hoʻopili i ka pae molekala kekahi i kekahi a me ka nui paʻa o ka metala. Hoʻolālā ʻia nā mea hope e hoʻolōʻihi i nā kaʻina hana corrosion e like me ka hiki, a hele mai ka passivation me ke kōkua o nā mea i loaʻa nā waiwai oxidizing. ʻO ka papa pale, e komo pū ana me nā mea passivating, e hoʻolohi i ka wikiwiki o ka ʻōpala o nā metala. ʻO ke kumu o ka hana o nā mea hoʻopiʻi adsorption ʻo ia ka hana ʻana i kahi kiʻiʻoniʻoni hou aʻe ma ka papa oxide, e hoʻonui ai i ka pale corrosion.
ʻO ka hopena o ka pilina o nā mea kemika
ʻO ka hui kemika o Tsincar hiki iā mākou ke kamaʻilio e pili ana i kēia anti-rust e like me kekahi o nā mea anti-corrosion maikaʻi loa e pili ana i ka pono. Ma hope koke o ka hoʻopili ʻana i ka hopena i ka papa metala i hoʻopili ʻia, hoʻomaka nā mea e hana ai i ka huahana e luku i ka pala, aʻo nā ʻano oxide o ke kila e hoʻololi ʻia i nā phosphate. I kēia kaʻina hana, hana ka manganese me ka zinc. Hāʻawi lākou i ka hoʻokumu ʻana i kahi papa pale hilinaʻi o nā mea hana.
