Polyaluminum chloride muaj cov khoom zoo li adsorption, condensation, nag thiab lwm yam, nws qhov ruaj khov tsis zoo, corrosive, xws li tsis txhob cia nchuav rau ntawm daim tawv nqaij kom ntxuav tam sim ntawd. Cov neeg ua haujlwm tsim khoom yuav tsum hnav khaub ncaws, lub ntsej muag, hnab looj tes, hnav khau roj hmab. Polyaluminum chloride muaj qhov zoo ntawm kev ruaj khov zoo ntawm kev tsuag kom qhuav, thaj chaw dej dav, hydrolysis ceev ceev, muaj peev xwm nqus tau zoo, paj alum loj, nag sai, dej tsawg turbidity thiab kev ua haujlwm zoo dehydration. Cov khoom tsuag kom qhuav tuaj yeem ua kom muaj kev nyab xeeb, txo cov xwm txheej dej, dej haus rau cov neeg nyob hauv tsev muaj kev nyab xeeb thiab txhim khu kev qha. Yog li ntawd, polyaluminum chloride, tseem hu ua high-efficiency polyaluminum chloride, high-efficiency PAC lossis high-efficiency tsuag kom qhuav polyaluminum chloride. Polyaluminum chloride yog tsim rau cov dej nyoos nrog ntau yam turbidity, nrog ntau yam kev siv pH, tab sis nws cov nyhuv sedimentation tsawg dua li polyacrylamide.
Qhov yooj yim ntawm polyaluminum chloride yog ib qho tseem ceeb hauv polyaluminum, tshwj xeeb tshaj yog rau cov dej haus polyaluminum khoom. Qhov qis dua cov ntsev hauv paus, qhov siab dua tus nqi, txhua tus neeg yuav khoom tuaj yeem ua haujlwm raws li qhov xwm txheej tiag tiag ntawm tus neeg tsim khoom. Tsis tas li ntawd, cov khoom siv raw sib txawv, cov txheej txheem sib txawv ntawm kev tsim khoom ntawm polyaluminum chloride khoom yog sib txawv hauv cov ntsev hauv paus, uas yuav tsum tau tus neeg tsim khoom los kho. Cov txiaj ntsig kev lag luam ntawm kev tsim khoom thiab kev siv tuaj yeem nce ntxiv los ntawm kev nce qib ntsev hauv paus ntawm polyaluminum chloride khoom. Qhov yooj yim yog nce los ntawm 65% mus rau 92%, tus nqi ntawm cov khoom siv raw tuaj yeem txo qis los ntawm 20%, thiab tus nqi ntawm kev siv tuaj yeem txo qis los ntawm 40%.
Cov xim ntawm polyaluminum chloride feem ntau muaj dawb, daj, tan, xim sib txawv ntawm polyaluminum chloride nyob rau hauv daim ntawv thov thiab ntau lawm technology kuj yog txawv heev. Lub polyaluminum chloride nrog cov ntsiab lus ntawm trialoxide nyob rau hauv qhov ntau ntawm lub teb chaws tus qauv xws li los ntawm 27% mus rau 30% yog feem ntau yog ib tug khoom hmoov ntawm kha-daj rau daj thiab lub teeb daj. Cov hom polyaluminum chloride muaj zoo dej solubility. Nyob rau hauv tus txheej txheem ntawm kev yaj, nrog rau lub cev thiab tshuaj hloov pauv xws li electrochemistry, coagulation, adsorption thiab nag lossis daus, cov flocs tsim ceev thiab tuab, muaj kev ua haujlwm siab, precipitate sai sai, thiab muaj qhov pom tseeb purification nyhuv rau siab turbidity dej. Dawb polyaluminum chloride vim nws yog lub npe hu ua siab purity tsis-hlau dawb polyaluminum chloride, lossis zaub mov qib dawb polyaluminum chloride, piv nrog nws polyaluminum chloride yog qhov zoo tshaj plaws cov khoom, lub ntsiab raw khoom yog zoo txhuas hydroxide hmoov, hydrochloric acid, cov txheej txheem ntau lawm yog qhov siab heev domestic technology tsuag kom qhuav txoj kev. Dawb polyaluminium chloride yog siv nyob rau hauv papermaking sizing neeg sawv cev, qab zib decolorizing thiab clarifying neeg sawv cev, tanning tawv, tshuaj, tshuaj pleev ib ce thiab precision casting thiab dej kev kho mob.
Cov khoom siv raw ntawm daj polyaluminium chloride yog calcium aluminate hmoov, hydrochloric acid, bauxite, feem ntau yog siv rau hauv kev kho dej phwj thiab kev kho dej haus, cov khoom siv raw siv rau kev kho dej haus yog txhuas hydroxide hmoov, hydrochloric acid, muaj me ntsis calcium aluminate hmoov, cov txheej txheem txais yuav yog lub phaj ncej lim txheej txheem lossis tshuaj tsuag kom qhuav txheej txheem. Rau kev kho dej haus, lub teb chaws muaj cov kev cai nruj ntawm cov hlau hnyav, yog li ob qho tib si cov ntaub ntawv raw thiab cov txheej txheem ntau lawm zoo dua li tan polyaluminium chloride. Daj polyaluminium chloride feem ntau yog tsim los ntawm lub nruas ziab lossis los ntawm tshuaj tsuag kom qhuav. Cov ntaub ntawv raw ntawm xim av polyaluminium chloride yog calcium aluminate hmoov, hydrochloric acid, bauxite thiab hlau hmoov. Cov txheej txheem ntau lawm yog txais yuav lub nruas ziab txoj kev, feem ntau yog siv rau hauv kev kho dej phwj, vim tias cov hlau hmoov ntxiv rau hauv yog li xim yog xim av, ntau hlau hmoov ntxiv, xim yog tsaus dua, hlau hmoov yog tias ntau dua li qee qhov nyiaj hauv qee lub sijhawm kuj hu ua polyaluminum-hlau chloride, hauv kev kho dej phwj muaj cov txiaj ntsig zoo heev.
