Polyaluminium Chloride yog dab tsi?
Polyaluminium chloride, abbreviated li PAC, yog inorganic polymer dej kho tus neeg saib xyuas. Cov hom tau muab faib ua ob pawg: kev siv dej haus hauv tsev thiab kev siv dej tsis siv neeg hauv tsev, txhua qhov kev kawm rau cov qauv sib txawv. Cov tsos mob tau muab faib ua ob hom: kua thiab khoom. Vim muaj cov khoom sib txawv uas muaj nyob rau hauv cov ntaub ntawv raw, muaj qhov sib txawv ntawm qhov tsos xim thiab cov teebmeem ntawm daim ntawv thov.
Polyaluminium chloride yog cov xim tsis muaj xim lossis daj. Nws cov tshuaj yog cov xim tsis muaj xim lossis daj xim av pob tshab, yooj yim soluble hauv dej thiab dilute cawv, insoluble hauv anhydrous cawv thiab glycerol. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua, qhuav, thiab huv warehouse. Thaum lub sij hawm kev thauj mus los, nws yog ib qho tsim nyog los tiv thaiv los nag thiab tshav ntuj ncaj qha, tiv thaiv deliquescence, thiab ua tib zoo saib xyuas thaum thauj khoom thiab tshem tawm kom tsis txhob ntim khoom puas. Lub sijhawm khaws cia rau cov khoom ua kua yog rau lub hlis, thiab rau cov khoom lag luam yog ib xyoos.
Cov tshuaj kho dej feem ntau yog siv los ntxuav cov dej haus, cov dej khib nyiab, thiab cov kav dej hauv nroog, xws li tshem cov hlau, fluorine, cadmium, cov pa phem, thiab cov roj ntab. Nws kuj yog siv rau kev kho dej khib nyiab, xws li luam ntawv thiab dyeing dej khib nyiab. Nws kuj yog siv hauv precision casting, tshuaj, papermaking, roj hmab, tawv ua, roj av, tshuaj lom neeg kev lag luam, thiab dyes. Polyaluminium chloride yog siv los ua tus neeg saib xyuas dej thiab cov khoom siv tshuaj pleev ib ce hauv kev kho deg.
Polyaluminium chloride muaj adsorption, coagulation, nag lossis daus thiab lwm yam khoom. Nws kuj muaj kev ruaj ntseg tsis zoo, toxicity, thiab corrosiveness. Yog hais tias yuam kev txaws ntawm daim tawv nqaij, yaug tam sim ntawd nrog dej. Cov neeg ua haujlwm tsim khoom yuav tsum hnav khaub ncaws ua haujlwm, qhov ncauj qhov ntswg, hnab looj tes, thiab khau looj plab hlaub ntev. Cov khoom siv ntau lawm yuav tsum raug kaw, thiab qhov chaw ua haujlwm cua yuav tsum zoo. Polyaluminium chloride decomposes thaum rhuab saum 110 ℃, tso hydrogen chloride gas, thiab thaum kawg decomposes rau hauv txhuas oxide; Reacts nrog cov kua qaub kom dhau depolymerization, ua rau txo qis hauv polymerization degree thiab alkalinity, thaum kawg hloov mus rau txhuas ntsev. Kev sib cuam tshuam nrog alkali tuaj yeem nce qib ntawm polymerization thiab alkalinity, thaum kawg ua rau tsim cov txhuas hydroxide precipitate lossis aluminate ntsev; Thaum tov nrog txhuas sulfate los yog lwm yam multivalent acid ntsev, nag los yog yooj yim generated, uas yuav txo tau los yog tag nrho cov coagulation kev ua tau zoo.
