Polyaluminium chloride yog lub siab ua pa dej, uas tuaj yeem ua kom tau zoo, thiab lwm yam. Tus nqi tau raug cawm dim los ntawm ntau tshaj 40%. Nws tau dhau los ua cov lim dej zoo heev uas tau lees paub hauv tsev thiab txawv teb chaws. Ntxiv rau, polyaluminate chloride tseem tuaj yeem siv los ntxuav cov dej haus tshwj xeeb xws li cov tshuaj tua dej, xws li cov tshuaj ntxuav yeeb yaj kiab, thiab roj kev qeeb qeeb.
PAC (Poly Aluminium Chloride) Nta:
Polyaluminium chloride yog nruab nrab ntawm Alcl3 thiab Alncl6-NLM] qhov twg m sawv daws cov degree ntawm polymerization thiab n sawv cev rau qib ntawm cov khoom pAC. Polyaluminium Chloride Pw tau raws li PAC yog feem ntau tseem hu ua polyaluminum chloride lossis COAGULANT, thiab >> Cov xim av tsaus nti, xim av tsaus nti. Cov khoom lag luam muaj cov khoom sib txawv nkauj nyab nraug adsorption, thiab thaum lub cev muaj txheej txheem hydrolysis, cov txheej txheem ntawm lub cev thiab tshuaj lom neeg thiab nag lossis daus.
PAC (Poly Aluminium Chloride) Daim Ntawv Thov:
Polyaluminium chloride yog siv rau cov dej hauv nroog thiab dej paug: Dej dej, dej hauv av, dej hauv av; Kev Siv Dej Dej Ua Si, Nroog Phwj Kev Kho Mob, Rov Qab Los Ntawm Cov Khoom Siv Hluav Taws Xob Hauv Kev Siv Dej Khib Nyiab, cov hmoov txhuv nplej siab ua haujlwm ntawm cov hmoov txhuv nplej siab; Polyaluminium chloride tuaj yeem ua kom huv ntau yam dej khib nyiab, cov tshuaj lim dej thiab cov dej khib nyiab pov tseg, cov tshuaj ntxuav tawv nqaij, cov quav dej lwg, cov quav dej khib nyiab, metallurgical quav, nqaij Ua kom dej lwg, thiab lwm yam .; Polyaluminium chloride rau kev kho dej phwj:
Qhov ntsuas qhov zoo ntawm PAC (polyaluminum chloride)
Peb yog peb qhov tseem ceeb tshaj plaws ntawm PAC (polyaluminum chloride)? Lub Supinity, P muaj nuj nqis, thiab alumina cov ntsiab lus uas txiav txim siab qhov zoo ntawm polyaluminum chloride yog peb qhov tseem ceeb tshaj plaws ntawm polyaluminum chloride.
1. Salinity.
Cov qib ntawm hydroxylation lossis alkalization ntawm ib daim ntawv nyob rau hauv PAC (polyaluminum chloride) yog hu ua qib ntawm theem pib lossis alkalinity. Nws yog feem ntau qhia los ntawm kev sib piv me colar ntawm txhuas hydroxide b = [Oh] / [AL] feem pua. Lub salinity yog ib qho tseem ceeb tshaj plaws ntawm polyaluminum chloride, uas yog ze rau cov flocculation. Lub siab dua cov dej nyoos thiab ntau dua lub salinity, qhov zoo dua cov txiaj ntsig flocculation. Txhawm rau kom suav, hauv ntau cov dej ntws tawm ntawm 86 ~ 10000mg / l, qhov zoo tshaj plaws salinity ntawm polyaluminum chloride muaj feem xyuam rau salinity.
2. PH tus nqi.
Lub pH ntawm PAC (polyaluminum chloride) kev daws teeb meem tseem yog qhov ntsuas tseem ceeb. Nws sawv cev tus nqi ntawm OH- hauv lub xeev dawb hauv kev daws teeb meem. Tus lej pH ntawm polyaluminum tshuaj tshuaj chloride feem ntau yuav nce nrog cov theem pib, tab sis rau cov kua nrog cov sib piv, tsis muaj kev sib raug zoo ntawm tus nqi PHIC thiab qhov yooj yim. Cov kua nrog tib lub qhov siab npau suav muaj qhov sib txawv ntawm cov pH muaj txiaj ntsig thaum lub siab sib txawv.
3. Alumina cov ntsiab lus.
Lub alumina cov ntsiab lus hauv PAC (Polyaluminum chloride) yog kev ntsuas ntawm cov khoom siv zoo ntawm cov khoom, uas muaj qee qhov kev sib raug zoo ntawm kev daws teeb meem. Feem ntau hais lus, ntau dua qhov kev txheeb ze ntau dua, ntau dua cov alumina cov ntsiab lus. Lub viscosity ntawm polyaluminum tshuaj tov yog cuam tshuam nrog cov ntsiab lus alumina, thiab viscosity nce nrog kev nce ntawm alumina cov ntsiab lus. Raws li tib qho kev mob thiab tib lub concumina, lub viscosity ntawm polyaluminum chloride yog qis dua li ntawm txhuas sulfate, uas yog ntau dua rau kev thauj mus los thiab siv.
