Hydroxypropyl methyl cellulose (HPMC)
Kuonekwa : Milky white or white powder
Carbonization tembiricha: 280-300%
Kupisa kwemavara: 190-200%
Particle size: 100 mesh pass rate yakakura kupfuura 98.8%; 80 mesh pass rate 99.9%; Iyo particle size yeyakakosha yakatarwa ndeye 40-60 mesh
Density inooneka: 0.25-0.70g/cm(kazhinji anenge 0.5g/cm), chaiyo inokwevera: 1.26-1.31
Solubility: inonyungudika mumvura uye zvimwe zvinonyungudutsa, zvakadai sechikamu chakakodzera che ethanol / mvura, propanol / mvura. The aqueous solution
ine basa repamusoro, kujeka kwepamusoro uye kushanda kwakagadzikana.
Hydroxypropyl methyl cellulose, inozivikanwawo sehydroxypropyl methyl cellulose, fiber bundle hydroxypropyl methyl ether, ndiyo sarudzo.
yeyakanyanya yakachena fiber fiber seyakagadzirwa pasi pemamiriro ealkaline neakakosha
etherification uye kugadzirira.Iine hunhu hwekukora kugona, munyu kuramba, kuderera kwedota, kugadzikana kwePH, kuchengetedza mvura.
dimensional kugadzikana, yakanakisa firimu kuumba, uye yakakura mildew kuramba,
dispersibility uye kunamatira.
Indasitiri yekuvaka
1.Cement dhaka
2.Ceramic tile simende
3.Asbestos uye imwe refractory coating: semumiriri wekumisa, fluidity inovandudza, asiwo inovandudza kunamatira kwe substrate.
4.Gypsum coagulant slurry: kuvandudza kuchengetedza kwemvura uye kushanda, kunatsiridza kunamatira kune substrate.
5.Joint simende: yakawedzerwa kune pasi yakabatana simende yegypsum board kuvandudza fluidity uye kuchengetedza mvura.
