Hydroxypropyl methyl cellulose, abbreviated li cellulose [HPMC], yog ua los ntawm cov paj rwb ntshiab heev cellulose li raw khoom, thiab yog npaj los ntawm tshwj xeeb etherification nyob rau hauv alkaline tej yam kev mob. Cov txheej txheem tag nrho yog ua tiav raws li kev soj ntsuam xyuas 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, ceramics, 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 cov mortar, muaj kev tiv thaiv kev tawg, thiab tuaj yeem txhim kho lub zog ntawm cov cement;
2. Cov nplais pobzeb: txhim kho cov yas thiab dej tuav ntawm cov pobzeb xovxwm, txhim kho cov nplaum quab yuam ntawm cov pobzeb, thiab tiv thaiv chalking;
3. Txheej ntawm asbestos thiab lwm yam ntaub ntawv refractory: raws li tus neeg sawv cev ncua kev kawm ntawv, fluidity improver, thiab kuj txhim kho cov adhesion 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. Plaster: Raws li muab tshuaj txhuam los ntawm cov khoom siv ntuj, nws tuaj yeem txhim kho cov dej tuav thiab txhim kho kev sib raug zoo nrog cov substrate;
8. Txheej: Raws li cov yas yas rau cov latex coatings, nws muaj kev cuam tshuam rau kev txhim kho kev khiav hauj lwm kev ua tau zoo thiab fluidity ntawm coatings thiab putty hmoov;
9. Txau txheej: Nws muaj cov txiaj ntsig zoo ntawm kev tiv thaiv cov cement lossis latex txau tsuas yog cov ntaub ntawv muab tub lim los ntawm kev tso dej thiab txhim kho fluidity thiab txau qauv;
10. Cement thiab gypsum cov khoom lag luam theem nrab: siv los ua extrusion molding binder rau hydraulic cov ntaub ntawv xws li cement-asbestos series los txhim kho fluidity thiab tau cov khoom zoo li molded;
11. Fiber phab ntsa: vim nws cov tshuaj tiv thaiv enzyme thiab cov kab mob los 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 npuas (PC version) rau lub luag haujlwm ntawm cov tshuaj khib nyiab, mortar, thiab cov neeg ua haujlwm plaster.
