Product Description:
Hydroxypropyl Methylcellulose (HPMC) ipfumbu chena isinganhuhwi, isina chepfu. Mushure mekunyungudika zvakakwana mumvura, ichaita sarudzo yakajeka viscous. Iyo isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer zvinhu kuburikidza neyakatevedzana yemakemikari kugadzirisa. Iyo ine hunhu hwekukora, kunamatira, kupararira, emulsification, kuumbwa kwemafirimu, kumiswa, adsorption, gelation, chiitiko chepamusoro, kuchengetedza unyoro uye kuchengetedzwa kwecolloids.
Application:
Kunyungudika kwemvura uye kugona kukora: inogona kunyungudika mumvura inotonhora, uye kugadzira yakajeka viscous mhinduro.
Dissolution mune organic solvents: Nekuti ine imwe huwandu hwe hydrophobic methoxy mapoka, chigadzirwa ichi chinogona kunyungudika mune mamwe organic solvents.
PH kukosha kugadzikana: The viscosity yeHPMC's aqueous solution haina kugadzikana muhuwandu hwePH kukosha 3.0-11.0.
Chiitiko chepamusoro: HPMC aqueous solution ine chiitiko chepamusoro. Iyo ine emulsifying mhedzisiro, inodzivirira kugona kwecolloid uye kugadzikana kwehama.
Thermal gelation: Kana yapiswa pamusoro peimwe tembiricha, iyo aqueous solution yeHPMC inogona kuita opaque, kuburitsa kunaya kwemvura, uye kurasikirwa neviscosity. Nekudaro, zvakachinja zvishoma nezvishoma kusvika kune yekutanga mhinduro mamiriro mushure mekutonhora.
Low ash content: HPMC haisi-ionic, inogona kushambidzwa nemvura inopisa panguva yekugadzirira uye kunyatsonatswa, saka madota ayo akaderera zvikuru.
Munyu kuramba: Sezvo chigadzirwa ichi isiri-ionic uye isiri-polymeric electrolyte, inenge yakagadzikana mune aqueous mhinduro dzesimbi munyu kana organic electrolytes.
Kuchengeta mvura mhedzisiro: Nekuti HPMC ndeye hydrophilic uye mhinduro yayo ine aqueous ine viscous yakanyanya. Inogona kuwedzerwa kune dhaka, gypsum, pende, nezvimwewo kuchengetedza mvura yakawanda yekuchengetedza muchigadzirwa.
Mildew resistance: Iine huturu hwakanaka, uye ine yakanaka viscosity kugadzikana panguva yekuchengeta kwenguva refu.
Lubricity: Kuwedzera HPMC kunogona kuderedza friction coefficient uye kunatsiridza lubricity ye extruded ceramic zvigadzirwa uye simende zvigadzirwa.
Firimu-yekugadzira chivakwa: Inogona kuburitsa yakasimba, inochinjika, yakajeka flakes ine yakanaka mafuta uye ester kuramba.
Muzvishandiso zvekuvaka, HPMC cellulose inogona kushandiswa senge inochengetedza mvura uye inodzoreredza simende slurry kuita kuti dhaka ripombike.
Sekunamatira, kushandiswa kweHPMC mumapurasita, gypsum, putty powder kana zvimwe zvinhu zvekuvaka zvinogona kuvandudza kupararira kwavo uye kuwedzera nguva yavo yekushanda.
Kuchengetedzwa kwayo kwemvura kunogona kudzivirira paste kubva pakutsemuka nekukurumidza mushure mekuputira, uye zvakare inogona kuwedzera kusimba kwejasi mushure mekuoma.
Kunze kwezvo, HPMC kemikari inogona zvakare kushandiswa sechinhu chinonamira chekusimudzira mataira, marble, uye kushongedzwa kwepurasitiki muindasitiri yekuvaka.
Pamusoro pezvo, HPMC poda inoshandiswa seyakakora, stabilizer, emulsifier, excipient, uye kuchengetedza mvura mukugadzirwa kweimwe indasitiri, senge petrochemicals, machira, zvekuvakisa, kubvisa pendi, makemikari ekurima, ingi, kudhinda machira uye dhayi. ceramics, papermaking, cosmetics, nezvimwewo.
Package: 25 kgs / bhegi kana sezvaunokumbira.
Kuchengeta: Chengetedza panzvimbo ine mhepo, yakaoma.
Mitemo yakaitwa: International Standard.
