Zibo Zhuoxing Chemical Co., Ltd yog ib qho ntawm cov kev ua kom qis pev hom pce hmoov muag khoom hauv Suav teb, muab cov khoom lag luam zoo tshaj plaws.
Cov lwg me ntawm polycarboxylic acid (ntsev) dej reducer yog tsim los ntawm txoj kev ntawm" comb" lossis" ntoo" qauv. Lub saw tseem ceeb ntawm cov qauv molecule muaj ntau lub ceg (sab txuas) ntawm qee qhov ntev thiab nruj.Muaj ib qho tseem ceeb, thaum lub saw tseem ceeb yog adsorbed nyob rau saum npoo ntawm cov nplais cement, cov ceg ntoo txuas tsim lub dav hlau sib txuas nrog cov ceg ntoo sib txuas ntawm lwm yam , tiv thaiv cov khoom tawm kom tsis txhob sib raug zoo, yog li ua tiav cov txiaj ntsig ntawm kev sib cais (piv txwv li txo cov dej) .Yuav ua li cas thiaj li paub txog kev txhim kho cov dej kom txo qis ntawm polycarboxylic acid?
1. Nws tuaj yeem tau ntxiv ncaj qha rau hauv cov qauv ntawm cov kua dej ua ntej lossis npaj rau hauv kev daws ntawm qee qhov kev xav, thiab tus nqi dej coj los ntawm polycarboxylic acid series ua haujlwm siab rau cov dej ua kom rov tuaj yeem txiav tawm.
2, vim tias cov dej tso tawm tus neeg sawv cev txo dej txo tus nqi yog loj, kev siv dej muaj qhov siab siab, kev siv dej yuav tsum yog kev tswj xyuas nruj.
3. Nws yuav tsum tsis txhob xyaw nrog naphthalene series cov dej siab-nqus tau tus neeg sawv cev. Thaum siv dej-txo tus neeg sawv cev, tus tov khoom yuav tsum raug muab ntxuav kom huv, txwv tsis pub nws yuav tsim tawm cov txiaj ntsig ntawm txo tus neeg sawv cev.
Thaum cov dej txuas ntxiv rau cov pob zeb ua ke, cov pab pawg hydrophobic ntawm cov dej reducer yog adsorbed nyob rau saum npoo ntawm cov npoo av, thiab cov pab pawg hydrophilic cov ntsiab lus rau cov kua dej aqueous tov los ua ib txheej-ntau los yog ntau cov qauv molecule adsorption film.Due rau kev taw qhia ntawm surfactant adsorption, xis mas colloidal hais saum npoo nrog rov qab kos npe them, yog li nyob rau hauv kev sib deev tsis sib haum, cov vaj tse - dej tsis tuaj yeem tsuas yog tsis muaj yoj yoj yoj nyob rau hauv daim ntawv ntawm kev ncua, thiab thaum pib ntawm dej tsim flocculation qauv kuj tuaj yeem sib sau thiab vau, thiab tso dej hauv cov qauv flocculation, ua tiav lub hom phiaj ntawm kev txo dej.
