HPMC Polymer

HPMC (Hydroxypropyl Methylcellulose) yog non-ionic, dej-soluble polymer muab los ntawm cellulose.Nws yog dav siv nyob rau hauv ntau yam kev siv, xws li tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab lwm yam lag luam.HPMC yog ntau yam polymer uas tuaj yeem siv los hloov kho lub cev lub cev ntawm cov tshuab aqueous, xws li viscosity, nto nro, thiab adhesion.

HPMC yog ib qho polysaccharide tsim los ntawm kev rov ua dua ntawm cov piam thaj molecules, uas tau txuas ua ke los ntawm ether thiab methyl pawg.Cov pab pawg ether muab HPMC nws cov dej-solubility, thaum cov methyl pawg muab cov polymer nrog nws cov yam ntxwv tsis-ionic.Qhov no ua rau HPMC yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv, vim nws tuaj yeem tawg tau yooj yim hauv dej thiab lwm cov kuab tshuaj polar.

HPMC yog siv nyob rau hauv ntau yam kev lag luam, xws li tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab lwm yam lag luam.Hauv kev lag luam kws tshuaj, HPMC yog siv los ua ib qho kev sib khi, disintegrant, thiab tus neeg ua yeeb yaj kiab.Nws kuj yog siv los ua ib qho excipient hauv cov ntsiav tshuaj thiab tshuaj ntsiav, raws li nws pab txhim kho cov flowability thiab compressibility ntawm hmoov.Hauv kev lag luam zaub mov, HPMC yog siv los ua cov thickener, stabilizer, thiab emulsifier.Nws kuj yog siv nyob rau hauv cov tshuaj pleev ib ce kev lag luam raws li ib tug zaj duab xis-tsim tus neeg sawv cev thiab emulsifier.

HPMC yog ib qho kev nyab xeeb thiab siv tau zoo polymer uas tsis muaj tshuaj lom thiab tsis ua rau khaus.Nws tseem yog biodegradable thiab environmentally friendly.HPMC muaj nyob rau hauv ntau qib thiab cov ntaub ntawv, xws li hmoov, granules, thiab flakes.Nws kuj tseem muaj nyob rau hauv qhov sib txawv molecular hnyav, uas tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb.

HPMC yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv vim nws muaj ntau yam, kev nyab xeeb, thiab ua haujlwm tau zoo.Nws yog tus nqi-zoo thiab txhim khu kev qha polymer uas tuaj yeem siv los hloov kho lub cev lub cev ntawm cov tshuab aqueous.HPMC yog ib qho tseem ceeb muaj nyob rau hauv ntau yam khoom, thiab nws cov kev siv yog zoo li yuav loj hlob mus rau yav tom ntej.
