Polyaluminium chloride, abbreviated li polyaluminum los yog polyaluminum chloride, abbreviated li PAC, kuj feem ntau hu ua dej purifying tus neeg saib xyuas los yog coagulant. Nws lub ntsiab tivthaiv yog aluminium oxide, piv txwv li alumina. Cov mis mos chemical yog [Al2 (OH) nCl6-n] m (m Tsawg dua lossis sib npaug rau 10, n=1 ~ 5)
Vim muaj cov qauv sib txawv, cov kev faib tawm ntawm polyaluminium chloride kuj muaj ntau haiv neeg. Yog tias muab faib los ntawm daim ntawv, nws tuaj yeem muab faib ua kua polyaluminium chloride thiab khoom polyaluminum chloride; Raws li kev faib tawm ntawm cov txheej txheem ziab, nws tau muab faib ua nruas hom polyaluminium chloride thiab tshuaj tsuag kom qhuav polyaluminium chloride. Nws tuaj yeem muab faib ua high-purity polyaluminum chloride, haus dej qib polyaluminum chloride thiab qib industrial polyaluminum chloride raws li qhov kev siv. Tam sim no, kev lag luam feem ntau siv txoj kev faib tawm raws li qhov sib txawv ntawm kev siv. Polyaluminum chloride muab faib ua high-purity polyaluminum chloride, haus dej qib polyaluminum chloride thiab qib industrial polyaluminum chloride.
Yog li dab tsi yog pawg ntawm polyaluminium chloride?
1. siab purity polyaluminium chloride, tseem hu ua zaub mov qib polyaluminium chloride, yog ib tug milky dawb hmoov. Cov ntaub ntawv tseem ceeb yog cov khoom siv zoo aluminium hydroxide thiab hydrochloric acid, thiab cov cuab yeej siv siab tshaj plaws yog tshuaj tsuag kom qhuav. High purity polyaluminium chloride yog dav siv hauv cov dej haus, dej hauv nroog thiab kev tsim cov dej huv huv, tshwj xeeb tshaj yog hauv kev lag luam papermaking, tshuaj, qab zib refining, tshuaj pleev ib ce additives, kev lag luam tshuaj niaj hnub thiab lwm yam.
2. haus dej qib polyaluminium chloride, cov khoom yog lub teeb daj hmoov. Cov ntaub ntawv tseem ceeb yog aluminium hydroxide, calcium aluminate thiab hydrochloric acid. Cov thev naus laus zis tshaj plaws yog tshuaj tsuag kom qhuav. Cov dej haus qib polychlorinated aluminium yog dav siv hauv cov dej haus, dej hauv nroog thiab kev ua dej huv.
3. qib kev lag luam polyaluminium chloride, cov khoom yog cov hmoov daj daj, cov khoom siv tseem ceeb yog calcium aluminate hmoov, bauxite thiab hydrochloric acid, ntau lawm technology yog tshuaj tsuag kom qhuav txheej txheem los yog nruas ziab txheej txheem. Kev lag luam qib polyaluminium chloride feem ntau yog tsim rau kev lag luam dej, dej khib nyiab, kev lag luam dej thiab hauv nroog cov dej phwj tuaj.
Polyaluminium chloride yog dej-soluble inorganic polymer coagulant. Vim nws ceev ceev flocculation thiab sedimentation ceev, dav siv pH nqi ntau, tsis muaj corrosion rau pipeline khoom thiab pom tseeb dej purification nyhuv, nws muaj peev xwm pab txhawb cov xim SS, COD, BOD, arsenic, mercury thiab lwm yam hnyav hlau ions hauv dej. Nws yog dav siv hauv dej haus, dej haus thiab dej phwj kho.
