Hydroxypropyl methylcellulose yog tsim los ntawm cov paj rwb ntshiab heev cellulose los ntawm tshwj xeeb etherification nyob rau hauv alkaline tej yam kev mob, thiab tag nrho cov txheej txheem yog tiav nyob rau hauv tsis siv neeg xyuas. Nws yog insoluble nyob rau hauv ether, acetone thiab kiag li ethanol, thiab swells mus rau hauv ib tug ntshiab los yog me ntsis cloudy colloidal tov nyob rau hauv dej txias. Cov tshuaj aqueous muaj cov dej num saum npoo av, siab pob tshab thiab kev ua haujlwm ruaj khov. Nws tuaj yeem siv los ua cov nplais pobzeb, marble, kho kom zoo nkauj yas, muab tshuaj ntxiv, thiab tuaj yeem txo cov cement. Cov dej tuav kev ua tau zoo ntawm hydroxypropyl methyl fiber tiv thaiv cov slurry los ntawm kev tawg vim yog ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening.
Nrog rau qhov txo qis ntawm cov ntsiab lus methoxyl, cov ntsiab lus gel nce, cov dej solubility txo qis, thiab cov dej ua haujlwm hauv qab kuj txo. Cov khoom kuj muaj cov yam ntxwv ntawm thickening muaj peev xwm, ntsev kuj, tsis tshua muaj tshauv hmoov, pH stability, dej tuav, seem stability, zoo heev zaj duab xis tsim, thiab ntau yam enzyme kuj, dispersibility thiab cohesiveness.
Nws yog siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam xim, thiab muaj kev sib raug zoo hauv dej los yog cov kuab tshuaj organic. Raws li cov xim tshem tawm. Nws yog siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam number case, thiab muaj kev sib raug zoo hauv dej los yog cov kuab tshuaj organic. Cov khoom no kuj tau siv dav hauv cov tawv nqaij, cov khoom siv ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile
