2. Acrylic thickeners:

Associative Thickeners:
Cov yam ntxwv: Cov tuab tuab ua viscosity los ntawm cov koom ua ke koom nrog hauv cov xim av matrix.
Cov ntawv thov: Siv dav hauv cov duab kos duab rau lawv cov versatility, lawv muab cov khoom ntws zoo thiab ua rau lawv haum rau ob qho tib si rau cov menyuam thiab txhuam cov ntawv thov.

Polyurethane thickenters:
Cov yam ntxwv: Polyurethane thickenters muaj zoo tshaj plaws sag kuj thiab leveling.
Cov ntawv thov: Lawv feem ntau ua haujlwm hauv cov txheej txheem ua haujlwm siab xws li cov xim xim thiab ntoo txheej txheem ntoo, muab cov yeeb yaj kiab zoo dua tsim thiab ntws tswj.

3. Cov av tuab tuab:

Bentonite:
Cov yam ntxwv: Bentonite yog cov av nplaum ntuj nrog cov khoom siab siab kawg.
Cov ntawv thov: Nws yog siv hauv cov xim pleev xim rau cov xim pleev xim thiab txheej ci los tiv thaiv kev sib txuam thiab txhim kho kev ruaj khov, tshwj xeeb hauv cov xim hlau hnyav xws li stucco thiab cov duab kos.

Tus cwj pwm:
Cov yam ntxwv: Cov neeg ua kom zoo muaj cov tshuaj ntsuab zoo heev thiab ruaj khov.
Cov ntawv thov: Nws feem ntau yog siv nyob rau hauv cov txheej txheej ntawm cov txheej txheem thiab cov xim pleev xim rau nws lub peev xwm los muab cov khoom lag luam tawm tsam thiab tiv thaiv kev tawm tsam.

4. Cov hluavtaws tuab:

Polyacrylic Acid (Paa):
Cov yam ntxwv: PAA muab cov viscosity siab ntawm cov kev sib haum xeeb thiab yog ph-rhiab.
Cov ntawv thov: Nws yog siv ntau ntawm cov xim av uas muaj cov xim dej ntau, suav nrog emulsion xim thiab cov primersion, rau nws cov khoom siv ua tuab thiab ua kom ruaj khov.
Hydrophobically hloov polyacrylates:

Cov yam ntxwv: Cov tuab no muab cov khoom ntws zoo thiab ua kom muaj nuj nqis.
Cov ntawv thov: feem ntau yog siv nyob rau hauv Adas Sab Hauv thiab Sab Nraud Pleev rau lawv muaj peev xwm txhim kho cov xim ua haujlwm thiab tsos.

5. Cellulosic thickeners:

Ethylhydroxyethyl cellulose (EHEC):
Cov yam ntxwv: EHEC muaj cov siab tuab tuab thiab ua tiav zoo nrog lwm cov xim ntxiv.
Cov ntawv thov: Nws yog dav siv nyob rau hauv looj cov xim tsev thiab hniav pleev xim rau nws tus cwj pwm shear-thuav thiab zoo heev.

Carboxymethyl cellulose (CMC):
Cov yam ntxwv: CMC muab cov viscosity nyob ruaj khov tshaj li cov xov tooj dav thiab ua yeeb yam zoo zaj duab xis-ua cov khoom ntiag tug.
Cov ntawv thov: Nws pom cov ntawv thov hauv cov txheej txheem tshwj xeeb xws li cov xov xwm tshwj xeeb thiab cov nplaum vim nws lub peev xwm txhawm rau txhim kho adhesion thiab dej tsis kam.

6. Alkali-o o emulsion (ase) thickeners:

Ase thickeners:
Cov yam ntxwv: Ase thickeners yog pH-rhiab thiab muab kev tswj zoo heev.
Cov ntawv thov: Lawv feem ntau siv hauv cov khoom ua tau zoo tshaj plaws ua yeeb yam, suav nrog cov duab xim sab nrauv thiab elastomeric txheej ci, rau lawv cov kev tshwj xeeb tuab thiab ruaj khov.

Thickeners yog indispensable additives hauv cov xim pleev xim rau hauv cov xim pleev xim, muab ib myriad ntawm cov txiaj ntsig tau los ntawm viscosity tswj rau sag tsis kam thiab ua haujlwm kom zoo. Los ntawm kev nkag siab txog cov yam ntxwv thiab cov kev siv ntawm ntau hom kev ua yeeb yam, cov xim pleev xim tuaj yeem ua kom tau raws li kev ua tau zoo rau cov ntawv thov sib txawv thiab substrates. Seb nws puas tau txhim kho cov txheej txheem zoo nkauj hauv cov xim ua kom ncaj ncees hauv cov xim tuab tuaj yeem txhim kho kev ua tau zoo tag nrho thiab cov neeg siv cov xim pleev xim.
