Qhov txawv thiab daim ntawv thov ntawm cationic, anionic thiab nonionic PAM?

Polyacrylamide(PAM) yog cov khoom siv ntau yam polymer dav siv hauv kev kho dej, ntawv ua, roj rho tawm thiab lwm yam haujlwm. Raws li nws cov khoom ionic, PAM muab faib ua peb hom: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) thiab nonionic (Nonionic PAM, NPAM). Peb hom no muaj qhov sib txawv loj hauv cov qauv, kev ua haujlwm thiab kev siv.

1. Cationic polyacrylamide (Cationic PAM, CPAM)

Structure thiab Properties:

Cationic PAM: Nws yog linear polymer compound. Vim tias nws muaj ntau pawg neeg nquag, nws tuaj yeem tsim hydrogen bonds nrog ntau yam tshuaj thiab feem ntau flocculate tsis zoo them colloids. Haum rau siv nyob rau hauv acidic tej yam kev mob

Daim ntawv thov:

- Kev kho dej khib nyiab: CPAM feem ntau yog siv los kho cov dej khib nyiab tsis zoo, xws li cov dej phwj hauv nroog, cov khoom noj khoom haus khib nyiab, thiab lwm yam. Cov nqi zoo tuaj yeem ua ke nrog cov khoom tsis zoo uas raug tshem tawm los ua flocs, yog li txhawb kev sib cais ntawm cov kua dej.

- Kev lag luam ntawv: Hauv cov txheej txheem papermaking, CPAM tuaj yeem siv los ua tus neeg sawv cev txhawb nqa thiab khaws cov neeg sawv cev los txhim kho lub zog thiab khaws cov ntawv.

- Cov roj rho tawm: Hauv cov roj av, CPAM yog siv los kho cov av nkos kom txo tau pom thiab ua kom tuab.

2. Anionic polyacrylamide (Anionic PAM, APAM)

Structure thiab Properties:

Anionic PAM yog cov dej-soluble polymer. Los ntawm kev qhia cov pab pawg anionic ntawm cov pob txha polymer, APAM tuaj yeem hnov ​​​​mob nrog cov khoom zoo. Nws yog tsuas yog siv rau flocculation, sedimentation thiab clarification ntawm ntau yam industrial wastewaters. Haum rau siv nyob rau hauv alkaline tej yam kev mob.

Daim ntawv thov:

- Kev kho dej: APAM tau siv dav hauv cov dej haus thiab kev kho dej khib nyiab. Nws muaj peev xwm condense tshem tawm hais los ntawm hluav taws xob neutralization los yog adsorption, yog li txhim kho cov clarity ntawm dej.

- Kev lag luam ntawv: Raws li kev khaws cia thiab pom kev pab, APAM tuaj yeem txhim kho cov dej pom kev ua haujlwm ntawm cov ntaub ntawv thiab lub zog ntawm daim ntawv.

- Mining thiab Ore Hnav Hnav: Thaum lub sij hawm flotation thiab sedimentation ntawm ore, APAM tuaj yeem txhawb cov sedimentation ntawm ore hais thiab txhim kho tus nqi rov qab ntawm ore.

- Kev Txhim Kho Av: APAM tuaj yeem txhim kho cov qauv av, txo cov av yaig, thiab siv dav hauv kev ua liaj ua teb thiab horticulture.

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM)

Structure thiab Properties:

Nonionic PAM yog ib lub siab molecular polymer los yog polyelectrolyte nrog ib tug npaum li cas ntawm polar noob nyob rau hauv nws cov molecular saw. Nws muaj peev xwm adsorb cov khoom raug tshem tawm hauv dej thiab txuas ntawm cov khoom los tsim cov floccules loj, ua kom cov sedimentation ntawm cov khoom nyob rau hauv ncua kev kawm ntawv, ua kom lub ntsiab lus meej ntawm kev daws, thiab txhawb kev pom. Nws tsis muaj pab pawg raug them thiab feem ntau yog tsim los ntawm cov pab pawg amide. Cov qauv no ua rau nws pom zoo solubility thiab stability nyob rau hauv nruab nrab thiab tsis muaj zog acidic tej yam kev mob. Nonionic PAM muaj cov yam ntxwv ntawm qhov hnyav molecular thiab tsis cuam tshuam los ntawm tus nqi pH.

Daim ntawv thov:

- Kev Kho Dej: NPAM tuaj yeem siv los kho cov dej tsis muaj turbidity, siab purity dej, xws li dej hauv tsev thiab dej haus. Nws qhov zoo dua yog tias nws muaj zog yoog raws rau kev hloov pauv hauv dej zoo thiab pH.

- Kev lag luam textile thiab dyeing: Hauv kev ua textile, NPAM yog siv los ua cov thickener thiab stabilizer los txhim kho cov xim adhesion thiab dyeing uniformity.

- Kev lag luam metallurgical: NPAM yog siv los ua cov roj nplua nyeem thiab cov dej txias hauv kev ua hlau kom txo tau kev sib txhuam thiab txhim kho kev ua haujlwm.

- Kev ua liaj ua teb thiab horticulture: Raws li cov av moisturizer, NPAM tuaj yeem txhim kho cov dej khaws cia ntawm cov av thiab txhawb cov nroj tsuag kev loj hlob.

Cationic, anionic thiab nonionic polyacrylamide muaj cov ntawv thov sib txawv thiab cov teebmeem vim lawv cov qauv tshuaj lom neeg thiab cov yam ntxwv. Kev nkag siab thiab xaiv qhov tsim nyogPAMhom tuaj yeem txhim kho kev ua tau zoo thiab cov teebmeem kom tau raws li qhov xav tau ntawm kev lag luam sib txawv.
