Hydroxypropyl methylcellulose
HydroxypropylMethylcellulose (HPMC) kana hypromelloserinobva pane rimwe divis yeMethyl cellulose ethers. Zvirichena kana isina-chena fibrous kana granularcellulose etherupfu. Iye zvino ndiyo cellulose ethers nekuita kwakanakisa munyika, kubatanidza kukora, kumisa, kuparadzira, emulsifying uye kudzikamisa. Hydroxypropyl methyl cellulose (HPMC) haina chepfu, iri nyore kushandisa, uye inonyungudika mumvura. Iyo polyanion mune aqueous mhinduro uye ine yakasarudzika yemuviri zvimiro. Iyo chaiyo performance ndeye se pazasi:

Features:
1. Solubility: Inenge isinganyungudike mu absolute ethanol, ether uye acetone, uye inonyunguduka kuva yakajeka kana zvishoma turbid colloidal solution mumvura inotonhora. Inogona kunyungudutswa mune mamwe organic solvents, uye inogona zvakare kunyungudika mune yakasanganiswa solvent yemvura-organic solvents.
2. Munyu kuramba: Inenge yakagadzikana mukugadzirisa kwemvura kana simbi yemunyu kana organic electrolytes iripo.
3. Surface chiitiko: inogona kushandiswa se colloid inodzivirira, emulsifier uye dispersant.
4. PH-kugadzikana: PH inokosha inenge yakagadzikana muhuwandu hwe3.0 ~ 11.0. Iyo viscosity yemushonga wemvura haina kukanganiswa neasidhi kana alkali.

Iyo yekutanga hydroxypropyl methyl cellulose(HPMC) inogona kuparadzirwa zvakaenzana mumvura inopisa, uye wobva wawedzera huwandu hwakasara hwemvura inotonhora kusvika Mumvura inopisa slurry, inotonhorera mushure mekusimudzira.
2. Powder mixing method: sanganisa iyo hydroxypropyl methyl cellulose(HPMC) hupfu nehumwe hukuru hwezvimwe zvinhu zvehupfu, zviparadzire nekusanganiswa kwakaoma, wobva wawedzera mvura kuti inyunguduke..
3. Organic solvent wetting method: tanga waparadzira kana kunyorovesa iyo hydroxypropyl methyl cellulose (HPMC) ne organic solvent, wobva wawedzera mvura kuti inyunguduse.
