Hydroxypropyl methyl cellulose, hu ua cellulose (HPMC), yog ua los ntawm cov paj rwb ntshiab heev cellulose ua raw khoom thiab yog tshwj xeeb etherified nyob rau hauv alkaline tej yam kev mob.Tag nrho cov txheej txheem yog ua tiav raws li kev soj ntsuam tsis siv neeg thiab tsis muaj cov khoom xyaw nquag xws li tsiaj cov kabmob thiab cov roj.
Cellulose HPMC muaj ntau yam kev siv, xws li zaub mov, tshuaj, chemistry, tshuaj pleev ib ce, kiln kev lag luam, thiab lwm yam. Cov nram qab no luv luv qhia nws daim ntawv thov nyob rau hauv kev tsim kho kev lag luam:
1. Cement mortar: txhim kho cov dispersion ntawm cement-xuab zeb, zoo heev txhim kho cov yas thiab dej tuav ntawm mortar, muaj kev tiv thaiv kev tawg, thiab txhim khu lub zog ntawm cov cement;
2. Cov nplais pobzeb: txhim kho cov yas thiab cov dej tuav ntawm cov pobzeb xovxwm, txhim kho qhov adhesion ntawm cov vuas, thiab tiv thaiv pulverization;
3. Txheej ntawm cov ntaub ntawv refractory xws li asbestos: raws li tus neeg sawv cev ncua, fluidity txhim kho tus neeg sawv cev, thiab tseem txhim kho lub zog sib txuas rau lub substrate;
4. Gypsum coagulation slurry: txhim kho cov dej tuav thiab kev ua haujlwm, thiab txhim kho adhesion rau substrate;
5. Joint cement: ntxiv rau cov cement sib koom ua ke rau gypsum board los txhim kho fluidity thiab dej tuav;
6. Latex putty: txhim kho fluidity thiab dej tuav ntawm putty raws li resin latex;
7. Stucco: Raws li cov tshuaj pleev ib ce uas hloov cov khoom ntuj tsim, nws tuaj yeem txhim kho cov dej tuav thiab txhim kho kev sib raug zoo nrog lub substrate;
8. Coatings: Raws li ib tug plasticizer rau latex coatings, nws muaj peev xwm txhim kho kev ua hauj lwm kev ua tau zoo thiab fluidity ntawm coatings thiab putty hmoov;
9. Txau cov xim: Nws muaj txiaj ntsig zoo ntawm kev tiv thaiv kev sib tsoo ntawm cov cement lossis latex txau cov ntaub ntawv thiab cov khoom ua kom zoo dua qub thiab cov qauv tshuaj tsuag;
10. Cov khoom thib ob ntawm cov cement thiab gypsum: siv los ua extrusion molding binder rau cov khoom siv hydraulic xws li cement-asbestos, txhim kho fluidity thiab tau cov khoom zoo li molded;
11. Fiber phab ntsa: Vim muaj cov tshuaj tiv thaiv enzyme thiab cov kab mob tiv thaiv kab mob, nws muaj txiaj ntsig zoo li cov ntaub ntawv rau cov xuab zeb phab ntsa;
12. Lwm tus: Nws tuaj yeem siv los ua tus neeg saib xyuas huab cua npuas (PC version) rau nyias cov av nplaum xuab zeb mortar thiab plaster tus neeg teb xov tooj.
