Polyacrylamide (PAM)

Polyacrylamide (PAM) yog cov dej-soluble polymer tsim los ntawm polymerization ntawm acrylamide. Cov tsos yog dawb granules los yog hmoov. Thiab nws yog soluble hauv dej thiab insoluble hauv organic teeb meem. PAM yog cov khoom siv hluavtaws tuaj yeem hloov kho rau ntau yam kev siv. Yog li PAM tshuaj tuaj yeem siv rau roj av kev tshawb nrhiav.water kho, textile, papermaking, ntxhia ua, tshuaj, kev ua liaj ua teb thiab lwm yam lag luam. lwm.

Taw qhia ntawm Polyacrylamide (PAM)

Cov polyacrylamide (PAM) tuaj yeem muab faib ua plaub hom, lawv yog anionic PAM, cationic PAM, nonionic andamphoteric PAM. Hauv qab no yog lawv cov ncauj lus kom ntxaws thiab specifications.

Anionic Polyacrylamide (APAM)

Qhov hnyav molecular ntawm anionic polymer flocculant feem ntau yog siab dua li ntawm cationic polymer lossis nonionicpolymer, thiab nws cov khoom meej meej yog tau txais los ntawm kev tsis txaus siab ntawm cov nqi. lts muaj nuj nqi feem ntau yog toflocculate tsis zoo them colloids, nrog rau kev ua haujlwm xws li turbidity tshem tawm thiab decolorization, thiab yog tsim nyog rau kev kho dej nrog cov organic colloid cov ntsiab lus siab.

APAM anionic polyacrylamide tuaj yeem siv dav hauv kev kho dej khib nyiab ntawm kev lag luam tshuaj lom neeg, kev kho dej hauv nroog, xws li kev ntxhua khaub ncaws, kev ua ntxhia, metallurgy, hlau thiab hlau kev lag luam thiab kev lag luam hluav taws xob. Anionic polymers yog siv rau hauv kev lag luam roj av rau kev txhim kho cov roj rov qab. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua papermaking auxiliary agent thiab textile pulping agent.

Cationic Polyacrylamide (CPAM)

Cationic polyacrylamide yog linear siab molecular polymer uas yog copolymerized los ntawm cationic monomer andacrylamide nyob rau hauv sib txawv proportions los ntawm advanced polymerization technology. Cov cationic polymer muaj cov yam ntxwv ntawm kev tawg sai sai, nqaim molecular hnyav faib thiab me me npaum li cas.

CPAM muaj txiaj ntsig zoo hauv kev siv thiab muaj lub cev qhuav dej ntau. Cationic polymer yog siv rau cov dej khib nyiab hauv lub Hoobkas cawv, monosodium glutamate Hoobkas, qab zib Hoobkas, haus dej haus, tanneries, dyeing thiab lwm yam teb. Nws muaj cov nyhuv zoo dua los siv ua ke nrog inorganic coagulant tshwj xeeb. Tsis tas li ntawd, cationic polyacrylamide tuaj yeem siv los ua cov ntawv ntxiv thiab.

Nonionic Polyacrylamide (NPAM)

Nonionic polyacrylamide yog ib qho zoo heev flocculant thiab tuaj yeem siv rau ntau hom dej phwj tuaj kho cov yam ntxwv yog: nws cov flocculation kev ua tau zoo tsis tshua muaj cuam tshuam los ntawm pH tus nqi ntawm cov dej khib nyiab thiab ntsev thiab lub zog flocculation siab dua li ntawm anionic flocculants, tshwj xeeb tshaj yog nyob rau hauv kev kho mob. acidic dej. cov nyhuv zoo dua li ntawm anionic PAM. Tsis tas li ntawd, hauv kev kho cov dej phwj tuaj hauv oilfields, nws feem ntau yog siv ua ke nrog inorganic flocculants.

Amphoteric polyacrylamide

Amphoteric polyacrylamide yog tau los ntawm hydrolysis thiab copolymerization ntawm vinyl amide thiab vinyl cationicmonomer acrylamide monomer. Tab sis nws tsis yog qhov sib xyaw ntawm anionic thiab cationic hom. lf cationic polyacrylamideis siv ua ke nrog anionic polyacrylamide, cov tshuaj tiv thaiv yuav ua rau nag lossis daus. Yog li ntawd, amphotericPAM yog cov khoom zoo tagnrho.

Cov amphoteric PAM molecules muaj cationic pawg thiab anionic pawg, thiab muaj cov yam ntxwv ntawm cationic flocculants, yog li nws yuav qhia tau zoo heev ua hauj lwm. Qhov no flocculant tuaj yeem siv rau hauv qhov dav ntawm pH tus nqi. muaj peev xwm lim dej siab thiab tsis muaj cov ntsiab lus noo noo ntawm lim ncuav mog qab zib. thiab tseem tuaj yeem siv rau cov kua qaub leaching ntawm ores los yog rov qab cov hlau tseem ceeb hauv cov hlau uas muaj cov kua qaub catalysts.
