Polyaluminum chloride yog lub tshuab lim dej ua haujlwm siab, uas tuaj yeem ua kom huv, tshem tawm ntxhiab, tshem tawm xim, thiab lwm yam. Vim nws cov yam ntxwv zoo tshaj plaws thiab cov txiaj ntsig zoo thiab ntau yam kev siv, cov koob tshuaj tuaj yeem txo tau ntau dua 30% piv rau cov tshuab lim dej ib txwm muaj, thiab tus nqi tuaj yeem txuag tau ntau dua 40%. Nws tau dhau los ua lub tshuab lim dej zoo heev uas tau lees paub hauv tsev thiab txawv teb chaws. Tsis tas li ntawd, polyaluminum chloride kuj tseem siv tau los ntxuav cov dej tshwj xeeb xws li dej haus thiab dej kais, xws li tshem tawm hlau, tshem tawm cadmium, tshem tawm fluorine, tshem tawm cov pa phem radioactive, thiab tshem tawm cov roj slick.
PAC (Poly Aluminium Chloride) Cov yam ntxwv:
Polyaluminum chloride nyob nruab nrab ntawm ALCL3 thiab ALNCL6-NLm] qhov twg m sawv cev rau qib polymerization thiab n sawv cev rau qib neutrality ntawm cov khoom PAC. Polyaluminum chloride luv ua PAC feem ntau kuj hu ua polyaluminum chloride lossis coagulant, thiab lwm yam. Cov xim yog daj lossis daj daj, xim av tsaus, grey tsaus resinous khoom. Cov khoom muaj cov khoom adsorption muaj zog, thiab thaum lub sijhawm hydrolysis, cov txheej txheem lub cev thiab tshuaj xws li coagulation, adsorption thiab nag lossis daus tshwm sim.
PAC (Poly Aluminium Chloride) Daim Ntawv Thov:
Polyaluminum chloride feem ntau yog siv rau kev muab dej hauv nroog thiab kev ntxuav dej: dej ntws, dej hauv pas dej, dej hauv av; kev ntxuav dej hauv kev lag luam, kev kho dej phwj hauv nroog, kev rov qab los ntawm cov khoom siv tau zoo hauv cov dej khib nyiab thiab cov khib nyiab pov tseg, txhawb kev tso dej ntawm cov thee pulverized hauv cov dej khib nyiab ntxuav thee, kev tsim cov hmoov txhuv nplej siab rov ua dua; polyaluminum chloride tuaj yeem ntxuav ntau yam dej khib nyiab hauv kev lag luam, xws li: luam ntawv thiab zas xim dej khib nyiab, cov dej khib nyiab tawv, cov dej khib nyiab uas muaj fluorine, cov dej khib nyiab hlau hnyav, cov dej khib nyiab uas muaj roj, cov dej khib nyiab ua ntawv, cov dej khib nyiab ntxuav thee, cov dej khib nyiab tsuas, cov dej khib nyiab ua npias, cov dej khib nyiab hlau, cov dej khib nyiab ua nqaij, thiab lwm yam; Polyaluminum chloride rau kev kho dej khib nyiab: kev ntsuas qhov loj ntawm daim ntawv, kev ua kom qab zib, kev ua pwm, kev tiv thaiv daim ntaub, kev thauj khoom catalyst, kev teeb tsa sai ntawm cov tshuaj kho kom zoo nkauj, cov khoom siv raw khoom zoo nkauj.
Qhov zoo ntawm PAC (polyaluminum chloride)
Peb yam tseem ceeb tshaj plaws ntawm PAC (polyaluminum chloride) yog dab tsi? Qhov ntsev, PH tus nqi, thiab cov ntsiab lus alumina uas txiav txim siab qhov zoo ntawm polyaluminum chloride yog peb yam tseem ceeb tshaj plaws ntawm polyaluminum chloride.
1. Ntshav ntsev.
Qhov degree ntawm hydroxylation lossis alkalization ntawm ib daim ntawv hauv PAC (polyaluminum chloride) yog hu ua degree ntawm basicity lossis alkalinity. Nws feem ntau yog qhia los ntawm molar piv ntawm aluminium hydroxide B = [OH] / [Al] feem pua. Qhov salinity yog ib qho ntawm cov cim qhia tseem ceeb tshaj plaws ntawm polyaluminum chloride, uas muaj feem cuam tshuam nrog cov nyhuv flocculation. Qhov siab dua ntawm cov dej nyoos concentration thiab qhov siab dua ntawm salinity, qhov zoo dua ntawm cov nyhuv flocculation. Hauv kev xaus, nyob rau hauv qhov ntau ntawm cov dej nyoos turbidity ntawm 86 ~ 10000mg / L, qhov zoo tshaj plaws salinity ntawm polyaluminum chloride yog 409 ~ 853, thiab ntau lwm yam ntxwv ntawm polyaluminum chloride muaj feem cuam tshuam nrog salinity.
2. Tus nqi pH.
Tus pH ntawm PAC (polyaluminum chloride) cov kua kuj yog ib qho cim qhia tseem ceeb. Nws sawv cev rau qhov ntau ntawm OH- hauv lub xeev dawb hauv cov kua. Tus nqi pH ntawm polyaluminum chloride feem ntau nce nrog rau qhov nce ntawm qhov basicity, tab sis rau cov kua uas muaj cov khoom sib txawv, tsis muaj kev sib raug zoo ntawm tus nqi pH thiab qhov basicity. Cov kua uas muaj tib qho salinity concentration muaj tus nqi pH sib txawv thaum qhov concentration sib txawv.
3. Cov ntsiab lus alumina.
Cov ntsiab lus ntawm alumina hauv PAC (polyaluminum chloride) yog qhov ntsuas ntawm cov khoom siv zoo ntawm cov khoom, uas muaj qee qhov kev sib raug zoo nrog qhov ceev ntawm cov tshuaj. Feem ntau hais lus, qhov ceev ntau dua, qhov siab dua ntawm alumina. Qhov viscosity ntawm polyaluminum chloride muaj feem cuam tshuam nrog cov ntsiab lus alumina, thiab viscosity nce nrog qhov nce ntawm cov ntsiab lus alumina. Nyob rau hauv tib yam mob thiab tib qhov concentration ntawm alumina, qhov viscosity ntawm polyaluminum chloride qis dua li ntawm aluminium sulfate, uas yog qhov zoo dua rau kev thauj mus los thiab kev siv.
