Aluminium chlorohydrate (ACH) thiab polyaluminum chloride (PAC) zoo li yog ob hom tshuaj sib xyaw uas siv los uaflocculants hauv kev kho dej. Qhov tseeb, ACH sawv ua cov tshuaj muaj zog tshaj plaws hauv PAC tsev neeg, xa cov ntsiab lus siab tshaj plaws ntawm alumina thiab qhov yooj yim ua tiav hauv cov ntaub ntawv ruaj khov lossis cov ntaub ntawv daws teeb meem. Ob qho tib si muaj kev ua yeeb yam txawv me ntsis, tab sis lawv qhov chaw thov txawv heev. Kab lus no yuav ua rau koj nkag siab tob txog ACH thiab PAC kom koj tuaj yeem xaiv cov khoom tsim nyog.
Polyaluminium chloride (PAC) yog ib lub siab molecular polymer nrog cov tshuaj formula [Al2(OH)nCl6-n]m. Vim nws cov khoom siv tshuaj lom neeg tshwj xeeb, nws muaj ntau yam kev siv hauv ntau qhov chaw.Polyaluminum chloride (PAC) plays lub luag haujlwm tseem ceeb hauv kev kho dej, tshem tawm cov khib nyiab pov tseg, cov tshuaj colloidal, thiab cov organic insoluble los ntawm cov txheej txheem coagulation. Los ntawm neutralizing particles, PAC txhawb kev sib sau ua ke, yooj yim rau lawv tshem tawm ntawm dej. PAC, feem ntau siv nrog rau lwm yam tshuaj xws li PAM, txhim khu cov dej zoo, txo cov turbidity, thiab ua tau raws li cov qauv kev lag luam.
Hauv kev tsim cov ntaub ntawv, PAC ua haujlwm raws li tus nqi-zoo flocculant thiab precipitant, txhim kho cov dej phwj tuaj thiab rosin-tsis nruab nrab sizing. Nws txhim kho cov teebmeem sizing, tiv thaiv cov ntaub thiab cov kab mob sib kis.
PAC cov ntawv thov txuas ntxiv mus rau kev lag luam mining, pab hauv kev ntxuav ore thiab sib cais cov ntxhia. Nws cais dej los ntawm gangue, yooj yim rov siv dua, thiab dehydrates sludge.
Hauv kev rho tawm roj av thiab kho kom zoo, PAC tshem tawm impurities, insoluble organic teeb meem, thiab hlau los ntawm cov dej khib nyiab. Nws demulsifies thiab tshem tawm cov roj tee, stabilizing wellbores thiab tiv thaiv tsim kev puas tsuaj thaum lub sij hawm roj drilling.
Textile luam ntawv thiab dyeing tau txais txiaj ntsig los ntawm PAC lub peev xwm los kho cov dej khib nyiab nrog cov ntim loj thiab cov khoom muaj kuab paug siab. PAC txhawb kom muaj zog, ceev ceev ntawm cov paj alum, ua tiav cov txiaj ntsig zoo kawg li.
ACH, Aluminium Chlorohydrate, nrog rau cov mis molecular Al2 (OH) 5Cl · 2H2O, yog ib qho inorganic polymer compound uas nthuav tawm ntau dua alkalization degree piv rau polyaluminium chloride thiab tom qab tsuas yog txhuas hydroxide. Nws undergoes choj polymerization los ntawm hydroxyl pawg, ua rau cov molecule uas muaj ntau tshaj plaws ntawm hydroxyl pawg.
Muaj nyob rau hauv kev kho dej thiab cov qib tshuaj niaj hnub (qib tshuaj pleev ib ce), ACH tuaj hauv cov hmoov (khoom) thiab kua (solution) cov ntaub ntawv, nrog rau cov khoom yog cov hmoov dawb thiab cov kua uas tsis muaj xim pob tshab.
Cov teeb meem insoluble thiab Fe cov ntsiab lus tsis tshua muaj, yog li nws tuaj yeem siv rau hauv cov tshuaj txhua hnub.
ACH pom ntau daim ntawv thov. Nws ua haujlwm raws li cov khoom siv raw rau cov kws tshuaj thiab cov tshuaj pleev ib ce tshwj xeeb, tshwj xeeb tshaj yog cov khoom siv tshuaj tua kab mob uas paub txog nws txoj kev ua tau zoo, tsis tshua muaj khaus, thiab kev nyab xeeb. Tsis tas li ntawd, ACH yog kim thiab yog li tsis tshua muaj siv los ua flocculant hauv dej haus thiab kev kho dej khib nyiab. ACH kuj tseem ua kom pom qhov ua tau zoo ntawm cov pH spectrum dav dua li cov pa hlau cov ntsev thiab cov dej qis hauv polyaluminum chlorides.
