Cov ntaub ntawv tseem ceeb ntawm polyaluminium chloride suav nrog calcium aluminate hmoov, hydrochloric acid, bauxite, thiab txhuas hydroxide. Ntau hom polyaluminium chloride tuaj yeem siv cov khoom sib txawv:
Cov ntsiab lus tsawg polyaluminium chloride tsuas yog siv calcium aluminate hmoov, hydrochloric acid, thiab bauxite.
Cov ntsiab lus siab polyaluminium chloride siv calcium aluminate hmoov, hydrochloric acid, bauxite, thiab txhuas hydroxide.
Txau kom qhuav polyaluminium chloride tsuas yog siv aluminium hydroxide thiab hydrochloric acid.
Basic aluminium chloride tsuas yog siv txhuas tshauv thiab hydrochloric acid.
Tsis tas li ntawd, kev tsim cov polyaluminium chloride kuj tseem siv tau cov khoom siv txhuas uas muaj cov khoom siv raw xws li hlau txhuas, khib nyiab aluminium shavings, grey aluminium, aluminium trichloride, coal gangue, thiab ya tshauv.
Polyaluminium chloride (PAC) yog cov khoom siv tsis muaj tshuaj lom neeg, cov khoom siv dej lim dej tawm tshiab thiab inorganic polymer coagulant, abbreviated li polyaluminium. Nws yog dej-soluble inorganic polymer ntawm AlCl3 thiab Al (OH) 3, nrog rau cov tshuaj formula [Al2 (OH) nCl6-n] m, qhov m sawv cev rau qib ntawm polymerization thiab n sawv cev rau qib ntawm nruab nrab. ntawm PAC cov khoom. N=1-5 yog cov khoom siv hluav taws xob hnyav heev nrog Keggin qauv, uas muaj cov txheej txheem siab ntawm electroneutralization thiab kev cuam tshuam ntawm cov colloids thiab cov khoom hauv dej, thiab tuaj yeem tshem tawm cov tshuaj lom micro thiab hnyav hlau ions, nrog cov khoom ruaj khov. Txoj kev tshuaj xyuas tuaj yeem ua raws li lub teb chaws tus qauv GB 15892-2003. Vim tias qhov cuam tshuam ntawm hydroxide ions thiab cov nyhuv polymerization ntawm ntau cov anions, cov khoom siv polyaluminum chloride yog ib qho inorganic polymer dej kho tus neeg sawv cev nrog qhov hnyav molecular hnyav thiab nqi.
Cov xim yog daj los yog lub teeb daj, tsaus xim av, los yog tsaus grey resin zoo li khoom. Cov khoom no muaj zog bridging adsorption kev ua tau zoo, thiab thaum lub sij hawm hydrolysis txheej txheem, lub cev thiab tshuaj txheej txheem xws li coagulation, adsorption, thiab nag lossis daus tshwm sim. Qhov sib txawv ntawm polyaluminium chloride thiab cov tshuaj inorganic coagulants nyob rau hauv qhov tseeb hais tias cov tshuaj inorganic coagulants yog cov tsis tshua muaj molecular crystalline ntsev, thaum polyaluminum chloride tus qauv yog tsim los ntawm ntau yam multi-carboxyl complexes nrog ceev flocculation thiab nag ceev, dav pH ntau, tsis muaj. corrosiveness rau pipeline khoom, pom tseeb dej purification nyhuv, thiab tau zoo tshem tawm hnyav hlau ions xws li SS, COD, BOD, arsenic, mercury, thiab lwm yam nyob rau hauv dej. Cov khoom no yog dav siv nyob rau hauv cov dej haus Muaj dej thiab dej phwj kho sector
