Hydroxypropyl methylcellulose yog ua los ntawm paj rwb cellulose ntshiab heev los ntawm kev tshwj xeeb etherification nyob rau hauv alkaline mob, thiab tag nrho cov txheej txheem yog ua tiav nyob rau hauv tsis siv neeg saib xyuas. Nws yog insoluble nyob rau hauv ether, acetone thiab ethanol kiag li, thiab swells mus rau hauv ib tug meej los yog me ntsis cloudy colloidal kua nyob rau hauv dej txias. Cov kua aqueous muaj ib tug nto kev ua ub no, siab pob tshab thiab ruaj khov kev ua tau zoo. Nws yuav siv tau raws li nplaum vuas, marble, yas kho kom zoo nkauj, nplaum reinforcement, thiab kuj yuav txo tau cov nyiaj ntawm cement. Lub dej-tuav kev ua tau zoo ntawm hydroxypropyl methyl fiber tiv thaiv cov slurry los ntawm kev tawg vim yog sai sai qhuav tom qab daim ntawv thov, thiab ua rau lub zog tom qab hardening.
Nrog rau qhov txo qis ntawm cov ntsiab lus methoxyl, qhov taw tes gel nce ntxiv, qhov dej solubility txo qis, thiab qhov ua haujlwm ntawm qhov chaw kuj txo qis. Cov khoom kuj muaj cov yam ntxwv ntawm kev muaj peev xwm tuab, tsis kam ntsev, hmoov tshauv qis, pH ruaj khov, khaws dej, ruaj khov qhov ntev, tsim zaj duab xis zoo heev, thiab ntau yam kev tiv thaiv enzyme, dispersibility thiab cohesiveness.
Nws yog siv los ua cov khoom ua kom tuab, cov khoom tawg thiab cov khoom ruaj khov hauv kev lag luam pleev xim, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Ua cov tshuaj tshem xim. Nws yog siv los ua cov khoom ua kom tuab, cov khoom tawg thiab cov khoom ruaj khov hauv kev lag luam kua mem, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Cov khoom no kuj siv dav hauv tawv, cov khoom ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile.
