Qhov sib txawv thiab kev thov ntawm cationic, anionic thiab noionic samam?

Polyacrylamide(Pam) yog ib qho kev siv polymer ntau yam siv hauv dej kho, papermaking, roj tawm thiab lwm thaj teb. Raws li nws ionic cov khoom, Pam tau muab faib ua peb hom tseem ceeb: Cationic Pam, oneionic PAM, APAM) thiab NONIONICAL PAM, NPAM). Peb hom no muaj qhov sib txawv tseem ceeb hauv cov qauv, muaj nuj nqi thiab daim ntawv thov.

1. Cationic Polyacrylamide (Cationic Pam, CPAM)

Cov qauv thiab cov khoom:

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

Daim Ntawv Thov:

- Kev kho dej khib nyiab: CPAM feem ntau siv los kho tsis zoo, xws li kev siv dej tsis zoo nrog cov khoom noj khoom haus, yog li txhawb kev ua kua-kua sib cais.

- Ntawv kev lag luam: Hauv cov txheej txheem papermakaking, CPAM siv tau los ua kev txhawb nqa tus neeg sawv cev thiab tuav tus neeg sawv cev thiab tuav cov ntawv.

- Cov roj tawm: hauv cov roj rauv teb, CPAM siv los kho cov av nkos kom txo cov kev lim dej thiab ua kom tuab.

2. Anionic Polyacrylamide (Anionic Pam, APAM)

Cov qauv thiab cov khoom:

Anionic Pam yog dej-soluble polymer. Los ntawm kev qhia cov pab pawg anionic no ntawm cov kab mob polymer, apam tuaj yeem hnov ​​mob nrog cov tshuaj zoo. Nws yog tsuas yog siv rau flocculation, sedimentation thiab qhia meej ntawm ntau yam wastewaters. Haum rau kev siv hauv alkaline tej yam kev mob.

Daim Ntawv Thov:

- Kev kho dej: Apam yog dav siv nyob rau hauv kev haus dej thiab kev kho dej nyab. Nws tuaj yeem tseem tab condense txwv los ntawm kev nruab nrab ntawm hluav taws xob lossis adsorption, yog li kev txhim kho ntawm dej.

- Ntawv kev lag luam: Raws li kev ua haujlwm thiab kev pab them nyiaj, APAM tuaj yeem txhim kho cov dej lim kom pom ntawm pulp thiab lub zog.

- Tsuas thiab ore Hnav: Thaum lub taub hau thiab kev ua yeeb yaj kiab thiab kev ua kom zoo nkauj tuaj yeem txhawb nqa kev ua kom tiav ntawm cov ore thiab txhim kho tus nqi rov qab.

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

3. Nonultionic Polyacrylamide (Noionic Pam, NPAM)

Cov qauv thiab cov khoom:

Nonionic Pam yog cov molecular polymer siab lossis polyelectrolyte nrog qee qhov nyiaj ntawm pololecular. Nws tuaj yeem adsorb khoom me me cais tawm hauv dej thiab choj nruab nrab ntawm cov lus loj hauv kev ncua, nrawm kom pom tseeb ntawm kev daws teeb meem, thiab txhawb nqa kev ua kom pom tseeb. Nws tsis muaj cov pab pawg thiab feem ntau yog siv cov pab pawg. Tus qauv no ua rau nws qhia tau solubility zoo thiab ruaj khov nyob rau hauv nruab nrab thiab qaug zog acidic tej yam kev mob. Nonionic Pam muaj cov yam ntxwv ntawm cov molecular hnyav thiab tsis muaj cuam tshuam ntau heev los ntawm PH tus nqi.

Daim Ntawv Thov:

- Kev kho dej: NPAM tau siv los kho cov turbity tsawg, muaj cov dej siab huv, xws li cov dej thiab haus dej. Nws qhov zoo dua yog tias nws muaj qhov muaj zog hloov kho kom hloov hauv dej zoo thiab Ph.

- Textile thiab dye kev lag luam: hauv textile ua, npam yog siv los ua cov thickener thiab stabilizer kom txhim kho cov xim nplaum thiab qhov tawg.

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

- Ua Liaj / teb thiab Horticulture: raws li cov av noo, NPAM tuaj yeem txhim kho cov dej ua kom muaj peev xwm kav dej thiab txhawb nqa cov nroj tsuag loj hlob.

Cationic, anionic thiab noionic polyacrylamide muaj cov ntawv thov sib txawv thiab cov teebmeem sib txawv vim lawv cov qauv tshuaj tshwj xeeb thiab them nqi. Nkag siab thiab xaiv qhov tsim nyogPamHom tuaj yeem txhim kho kev txuag nyiaj ntau thiab cuam tshuam kom tau raws li qhov kev xav tau ntawm kev lag luam sib txawv.
