1. Polyaluminium chloride (PAC) muaj cov khoom adsorption, coagulation, thiab nag lossis daus, tab sis nws qhov kev ruaj ntseg tsis zoo thiab nws yog corrosive. Yog hais tias nws txaws rau ntawm daim tawv nqaij, yaug tam sim ntawd nrog dej.
2. PAC muaj qhov zoo xws li kev ruaj ntseg zoo tom qab ziab kom qhuav, siv dav rau ntau lub cev dej, hydrolysis sai, muaj zog adsorption muaj peev xwm, loj thiab ntom flocs, sai sedimentation, tsawg effluent turbidity, thiab zoo dewatering kev ua tau zoo. Kev siv tshuaj tsuag- cov khoom qhuav ua kom muaj kev nyab xeeb, txo cov dej sib tsoo, thiab muaj kev nyab xeeb heev thiab txhim khu kev qha rau cov dej haus hauv tsev. Yog li ntawd, PAC kuj tsuas yog hu ua high-efficiency polyaluminum chloride, siab -efficiency polyaluminum chloride, los yog siab -efficiency spray-polyaluminum chloride qhuav. PAC yog tsim rau cov dej nyoos ntawm ntau yam turbidities thiab muaj pH dav, tab sis nws cov nyhuv sedimentation yog deb tshaj ntawm polyacrylamide.
3. Cov tsos thiab xim: Cov ntaub ntawv zoo sib xws ntawm PAC yog xim daj, lub teeb daj, lossis cov hmoov dawb los yog granules. Qhov tob ntawm cov xim yog feem ntau cuam tshuam nrog nws cov ntaub ntawv raw thiab txheej txheem kev npaj. Xim variations feem ntau cuam tshuam nrog hlau ion impurities; purity ntau dua ua rau cov xim sib dua. Dawb polyaluminum chloride, tseem hu ua siab -purity hlau- dawb dawb polyaluminum chloride los yog zaub mov-qib dawb polyaluminum chloride, yog cov khoom zoo tshaj plaws piv rau lwm cov polyaluminum chlorides. Nws tuaj yeem siv rau hauv ntau qhov chaw xws li cov ntawv sizing cov neeg ua haujlwm, cov khoom qab zib decolorizing thiab qhia meej, tanning, tshuaj, tshuaj pleev ib ce, precision casting, thiab dej kho. Yellow polyaluminium chloride yog tsim los ntawm calcium aluminate hmoov, hydrochloric acid, thiab bauxite, thiab tsuas yog siv hauv cov dej khib nyiab thiab dej haus. Rau kev kho dej haus, cov khoom siv raw yog aluminium hydroxide hmoov, hydrochloric acid, thiab ib qho me me ntawm calcium aluminate hmoov. Cov txheej txheem kev siv yog phaj thiab thav duab pom lossis tshuaj tsuag kom qhuav. Brownish-liab polyaluminum chloride yog tsim los ntawm calcium aluminate hmoov, hydrochloric acid, bauxite, thiab hlau hmoov. Cov kua polyaluminium chloride feem ntau yog daj ntseg daj rau cov kua tsis muaj xim pob tshab nrog cov concentration ntawm 10% -20%. Nws cov xim thiab concentration sib txawv nyob ntawm seb qhov℃ntawm polymerization thiab acidity ntawm aluminium chloride.
