Paub meej! Kev txiav txim ntawm flocculation nyhuv ntawm PAC thiab PAM

Polyaluminium Chloride (PAC)

Polyaluminium chloride (PAC), hu ua polyaluminum luv luv, Poly Aluminium Chloride dosing In Water Treatment, muaj cov tshuaj formula Al₂Cln(OH)₆-n. Polyaluminium Chloride Coagulant yog ib tug inorganic polymer dej kho tus neeg saib xyuas nrog loj molecular hnyav thiab siab nqi uas tsim los ntawm lub bridging nyhuv ntawm hydroxide ions thiab lub polymerization ntawm polyvalent anions. Poly Aluminium Chloride Pac tuaj yeem muab faib ua cov khoom thiab cov kua hauv daim ntawv. Khoom polyaluminium Yellow, grey-ntsuab, tsaus xim av hmoov. Pac kua yog yooj yim cuam tshuam los ntawm noo noo thiab yooj yim soluble nyob rau hauv dej. Cov txheej txheem hydrolysis yog nrog cov txheej txheem ntawm lub cev thiab tshuaj xws li electrochemistry, agglutination, adsorption, thiab nag lossis daus, thiab muaj zog bridging adsorption zog.

1. Mechanism ntawm kev ua

Cov tshuaj aqueous ntawm PAC tshuaj yog cov khoom siv hydrolysis ntawm FeCl₃ thiab Al (OH)₃, nrog rau cov nqi colloidal, yog li nws muaj zog adsorption rau tshem tawm cov khib nyiab hauv dej, thiaj li ua tiav lub hom phiaj ntawm coagulating suspended solids hauv dej.

2. Khoom nta

● Polyaluminium chloride yog tshuaj ruaj khov nyob rau hauv chav tsev kub, thiab yuav tsis deteriorate tom qab cia mus ntev. Cov khoom siv polyaluminium tau yooj yim absorbs ya raws, tab sis tsis deteriorate, thiab yog non-toxic thiab harmless.

● Tus nqi pH ntawm cov dej uas tsim nyog yog 4-14, tab sis tus nqi pH ntawm qhov kev kho kom zoo yog 6-8.

● Poly Aluminium Chloride Powder muaj cov yam ntxwv ntawm kev siv me me, tus nqi qis, kev ua haujlwm siab, kev ua haujlwm yooj yim, kev siv dav dav thiab tsis tshua muaj corrosiveness.

Polyacrylamide (PAM)

Polyacrylamide (PAM) / nonionic polyacrylamide / cation polyacrylamide / anionic polyacrylamide, alias flocculant No. 3, yog cov dej-soluble linear polymer tsim los ntawm dawb radical polymerization ntawm acrylamide (AM) monomer. Coagulation thiab flocculation txheej txheem nyob rau hauv dej kho, Polyacrylamide sds muaj zoo flocculation thiab yuav txo tau kev sib txhuam ntawm cov kua Resistance yuav muab faib ua plaub hom: anionic, cationic, nonionic thiab amphoteric raws li ionic zog.

Polyacrylamide yog cov hmoov dawb dawb, uas tuaj yeem yaj hauv dej hauv txhua qhov kev faib ua feem, cov tshuaj aqueous yog ib yam thiab pob tshab, thiab cov viscosity ntawm cov tshuaj aqueous nce ntxiv nrog qhov nce ntawm cov txheeb ze molecular hnyav ntawm cov polymer. PAM yog insoluble nyob rau hauv feem ntau cov organic solvents, xws li formaldehyde, ethanol, acetone, ether, thiab lwm yam.

1. Mechanism ntawm kev ua

Polyacrylamide yog dej-soluble polymer lossis polyelectrolyte. Muaj qee tus naj npawb ntawm cov polar pawg hauv PAM cov saw hlau molecular, uas tuaj yeem nqus tau cov khoom seem uas raug tshem tawm hauv cov dej phwj tuaj, ua cov txuas txuas ntawm cov khoom los yog los ntawm cov nqi nruab nrab, kom cov khoom tuaj yeem ua rau cov flocs loj. Yog li ntawd, polyacrylamide tuaj yeem ua kom cov khib nyiab tshem tawm. Cov sedimentation ntawm cov khoom nruab nrab muaj qhov pom tseeb heev ntawm kev ua kom cov ntsiab lus meej meej thiab txhawb kev pom.

2. Sau ntawv

Polyacrylamide muaj tshuaj lom unpolymerized acrylamide monomer. Hauv kev kho dej haus uas tau teev tseg hauv kuv lub tebchaws, qhov siab tshaj plaws tau tso cai yog 0.01mg / L. Txhawm rau tiv thaiv qhov degradation ntawm polyacrylamide, qhov ntsuas kub ntawm nws cov kua dej yuav tsum tau tswj kom tsis txhob siab tshaj 40 ° C. Txhawm rau tiv thaiv kom tsis txhob raug tshav ntuj, ib qho me me ntawm stabilizer, xws li sodium thiocyanate, sodium nitrite, thiab lwm yam, tuaj yeem muab ntxiv rau cov tshuaj. Polyacrylamide khoom hmoov yuav tsum tau ntim rau hauv cov nruas hlau uas npog nrog cov hnab ntim dej noo-pov thawj polyethylene lossis lined nrog polyethylene txheej, thiab kaw kom tsis txhob raug cov av noo siab.

Cov kua polyacrylamide yuav tsum tau ntim thiab muab tso rau hauv cov thawv ntoo lossis cov thawv hlau. Lub sijhawm khaws cia yog li 3 txog 6 lub hlis. Nws yuav tsum tau stirred ua ntej siv. Qhov kub cia yuav tsum tsis txhob siab tshaj 32 ° C thiab qis dua 0 ° C.
