Hydroxypropyl methyl cellulose (HPMC)
Cov tsos mob: Milky dawb los yog hmoov dawb
Carbonization kub: 280-300%
Xim kub: 190-200%
Particle loj: 100 mesh pass tus nqi yog ntau dua 98.8%; 80 mesh pass tus nqi 99.9%; Qhov loj me me ntawm tshwj xeeb specification yog 40-60 mesh
Pom meej ntom ntom: 0.25-0.70g / cm (feem ntau yog 0.5g / cm), tshwj xeeb lub ntiajteb txawj nqus: 1.26-1.31
Solubility: soluble hauv dej thiab qee cov kuab tshuaj, xws li kev faib ua feem ntawm ethanol / dej, propanol / dej.The aqueous tov
muaj kev ua haujlwm saum npoo, siab pob tshab thiab kev ua haujlwm ruaj khov.
Hydroxypropyl methyl cellulose, tseem hu ua hydroxypropyl methyl cellulose, fiber ntau pob hydroxypropyl methyl ether, yog kev xaiv
ntawm cov paj rwb ntshiab heev li raw khoom raws li alkaline tej yam kev mob los ntawm tshwj xeeb
etherification thiab kev npaj.Nws muaj cov yam ntxwv ntawm thickening peev xwm, ntsev tsis kam, tsis tshua muaj tshauv ntsiab lus, PH stability, dej tuav
Dimension stability, zoo heev zaj duab xis tsim, thiab dav mildew kuj,
dispersibility thiab adhesion.
Kev tsim kho kev lag luam
1.Cement mortar
2.Ceramic pobzeb cement
3.Asbestos thiab lwm yam refractory txheej: raws li tus neeg sawv cev ncua kev kawm ntawv, fluidity improver, tab sis kuj txhim kho cov adhesion ntawm substrate
4.Gypsum coagulant slurry: txhim kho dej tuav thiab ua haujlwm, txhim kho adhesion rau substrate
5.Joint cement: ntxiv rau hauv av sib koom ua ke cement rau gypsum board los txhim kho cov dej ntws thiab dej tuav
