(HPMC) Ndeupi musiyano urwo kana pasina?

Zvinoita sekunge uri kurevaHydroxyprupyl methylcellose (HPMC), Polymer anoshandiswa zvakanyanya mumasango akasiyana siyana anosanganisira mishonga, kuvaka, chikafu, uye zvizoro. Musiyano uripo pakati peHPMC ne uye pasina tsamba '

HydroxyPropyl methylcellose (HPMC) ndeye semi-synthetic, inert, viscoelastic polymer kubva cellulose. It's typically produced through the chemical modification of cellulose, which involves treating cellulose with alkali and propylene oxide to introduce hydroxypropyl and methyl groups.

Heano mamwe manhamba makuru nezve HPMC:

Chemical chimiro: HPMC ine marefu marefu ezvikamu zveGlucose neHydroxypruppropyl uye methyl mapoka akasungirirwa kune imwe yeiyo hydroxyl (-OOOH) mapoka. Iyo chiyero chevatori ava chinogona kusiyana, zvichitungamira kumakiredhi akasiyana eHPMC neakasiyana zvivakwa.

Zvivakwa zvepanyama: HPMC iri manyorerwo-mhou uye maficha anojekeswa, viscous mhinduro kana ikanyungudika mumvura. View viscosity yaro inogona kudzorwa nekugadzirisa paramita senge smecular uremu, degree rekutsiva, uye kusvinura.

Zvishandiso:

Pharmaceutals: Hpmc inowanzoshandiswa mune yemishonga yekugadzira sedhikeneri, binder, yefirimu yaimbove, uye yakasungirirwa-mumiririri mumatafura, mahwendefa, uye mafomu epamusoro.
Kuvakwa: Muzvinhu zvekuvaka zvakadai semutya, zvinopa, uye madhimoni, HPMC inovandudza kushanda, kuchengetwa kwemvura, uye kuderedza.
Chikafu: HPMC inoshandiswa mune zvigadzirwa zvekudya seanotenda, stabilizer, uye emulsifier. Zvinowanzowanikwa mune makirogiramu zvigadzirwa, sosi, uye madhutsu.
Cosmetics: HPMC inosanganisirwa mune cosmetics uye yeyako yekuchengetedza zvigadzirwa semakirimu, lotioos, uye shampoos kuti isimbise chimiro, kugadzikana, uye mafirimu ekuumba mafirimu.

Zvakanakira:

HPMC inopa yakanakisa mvura yekuchengetwa, iyo yakakosha kune zvikumbiro kunge motars-yakavakirwa motars iyo hydration yakakwana inodiwa pakurapwa kwakaringana.
Inovandudza kudiwa uye kushanda mune zvekuvaka, zvinopa mukuita zviri nani uye kusimba.
Mune mishonga yemishonga, HPMC inofambisa inodzora zvinodhaka zvinodhaka uye zvinovandudza piritsi rekuparadzira zvinhu.
HPMC inoonekwa yakachengeteka pakushandisa uye inogamuchirwa zvakanyanya mune zvekudya uye zvigadzirwa zvezvigadzirwa.
Mamakisi uye dudziro: HPMC inowanikwa mumakiredhi akasiyana uye madimikira akagadziridzwa kune zvakanyatso mafaro. Izvi zvinosanganisira misiyano muViscosity, sizehure, kutsiva chikamu, uye zvimwe zvikamu kuzadzisa zvinodiwa zvemaindasitiri akasiyana uye mafambiro.

Nzvimbo yekudzora: HPMC inowanzozivikanwa seyakachengeteka (gras) nevematare ekuzvidzora seUS chikafu uye zvinodhaka

HPMC inhengo yemuviri ine polymer ine dzakasiyana-siyana maapplication maindasitiri. Zvivakwa zvayo zvinogona kuve zvakarongedzwa kuti usangane chaizvo zvinodiwa, zvichiita kuti ive yakakosha musimboti mune dzakasiyana siyana mafomu uye zvigadzirwa. Kana iwe uine rumwe ruzivo rwakajeka pamusoro peHPMC neHPMC ne kana pasina tsamba 's', ndapota ipa imwe mamiriro ekuwedzera kune imwe tsananguro yakatarwa.
