Hydroxypropyl methyl cellulose, luv ua cellulose [HPMC], yog ua los ntawm cov paj rwb ntshiab heev ua cov khoom siv raw, thiab tau npaj los ntawm kev sib xyaw tshwj xeeb hauv qab alkaline. Tag nrho cov txheej txheem tau ua tiav hauv kev saib xyuas tsis siv neeg thiab tsis muaj cov khoom xyaw nquag xws li cov tsiaj txhu thiab roj.
Cellulose HPMC muaj ntau yam kev siv, xws li khoom noj, tshuaj, tshuaj lom neeg, tshuaj pleev ib ce, ceramics, thiab lwm yam. Cov hauv qab no qhia luv luv txog nws daim ntawv thov hauv kev lag luam kev tsim kho:
1. Cov cement mortar: txhim kho qhov kev sib kis ntawm cov cement-xuab zeb, txhim kho qhov plasticity thiab dej khaws cia ntawm cov mortar, muaj cov nyhuv rau kev tiv thaiv kev tawg, thiab tuaj yeem txhim kho lub zog ntawm cov cement;
2. Cov cement pobzeb: txhim kho qhov plasticity thiab dej tuav ntawm cov pobzeb mortar nias, txhim kho lub zog nplaum ntawm cov pobzeb, thiab tiv thaiv chalking;
3. Txheej ntawm asbestos thiab lwm yam khoom siv refractory: ua tus neeg sawv cev ncua, fluidity improver, thiab tseem txhim kho qhov adhesion rau lub substrate;
4. Gypsum coagulation slurry: txhim kho kev khaws cia dej thiab kev ua haujlwm, thiab txhim kho kev nplaum rau lub substrate;
5. Cov cement sib koom ua ke: ntxiv rau cov cement sib koom ua ke rau gypsum board los txhim kho kev ntws thiab kev khaws cia dej;
6. Cov tshuaj nplaum latex: txhim kho qhov fluidity thiab dej khaws cia ntawm cov tshuaj nplaum raws li cov tshuaj nplaum latex;
7. Cov Nplaum: Ua ib qho nplaum es tsis yog cov khoom siv ntuj, nws tuaj yeem txhim kho kev khaws dej thiab txhim kho lub zog sib txuas nrog lub substrate;
8. Txheej: Ua ib qho plasticizer rau cov txheej latex, nws muaj kev cuam tshuam rau kev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov txheej thiab cov hmoov putty;
9. Tshuaj tsuag txheej: Nws muaj cov txiaj ntsig zoo rau kev tiv thaiv cov cement lossis latex tsuag tsuas yog cov khoom siv los ntawm kev poob thiab txhim kho cov kua thiab cov qauv tsuag;
10. Cov khoom siv cement thiab gypsum theem nrab: siv ua cov khoom siv extrusion molding rau cov ntaub ntawv hydraulic xws li cement-asbestos series los txhim kho kev fluidity thiab tau txais cov khoom pwm sib xws;
11. Phab ntsa fiber: vim nws cov tshuaj tiv thaiv enzyme thiab tshuaj tiv thaiv kab mob, nws zoo li cov khoom siv rau cov phab ntsa xuab zeb;
12. Lwm tus: Nws siv tau ua tus neeg sawv cev rau cov npuas dej (PC version) rau lub luag haujlwm ntawm cov mortar nyias, mortar, thiab plaster operators.
