Waba uzi ibya Hypromellose?

HydroxyPropyl MethylcellUlose (Inn Izina: Byoroheje Izina) Nigisigisigi-synthique, polymer polymer, vielymer isanzwe ikoreshwa nka lubricilmologymologymology, cyangwa nkigicura cyimiti yo mu kanwa, kandi mubisanzwe iboneka mubicuruzwa bitandukanye byubucuruzi.

Nkibiryo byongeweho, Hyppimellose birashobora gukina inshingano zikurikira: Emulsifuer, Thickener, ihagarika ingwe no gusimbuza gelatin gelatin. Kode yayo (e-code) muri codex alimentarius ni E464.

Imiti yimiti:

Igicuruzwa cyarangiye cya hydroxyproppopyl methylcellse ni ifu yera cyangwa yera ihamye cyane, kandi ingano yera irarengana kugeza kuri 80-mesh. Ikigereranyo cy'ikintu kirimo kuri hydroxyproppopyle ibikubiye ibicuruzwa byarangiye biratandukanye, kandi viscometity iratandukanye, bityo biba ubwoko butandukanye butandukanye. Ifite ibiranga yo gushonga mumazi akonje kandi ihungaba mumazi ashyushye asa na methyl selile Irashobora gushonga muri methanol anhydrous na ethanol, kandi irashobora gushonga muri hydrocarbone nka dichloroethane nka acetone, inzoga za IsOine, na Diacetone. Iyo gushonga mumazi, bizahuza na molekile y'amazi kugirango ikore colloid. Birahamye aside na alkali, kandi ntabwo bigira ingaruka kurwego rwa PH = 2 ~ 12. HYPROMMOMELLOSE, nubwo idafite uburozi, iraka kandi yitabira cyane hamwe nibikoresho bya okiside.

Ibyatsi bibi bya HPMC byiyongera hamwe no kwiyongera kw'ibintu byo kwibanda n'uburemere bwa molekile, kandi iyo ubushyuhe buzamutse, ubushyuhe bwayo butangira kugabanuka. Iyo bigeze ku bushyuhe runaka, viscosity irazamuka gitunguranye kandiga bibaho. uburebure bwa. Igisubizo cyacyo gihamye kirahagaze ubushyuhe bwicyumba, usibye ko gishobora guteshwa agaciro na enzymes, kandi virusi ya rusange ntabwo ifite ibintu byangiza. Ifite imiterere yihariye yubushyuhe, imiterere nziza ya firime hamwe nibikorwa byo hejuru.

Gukora:

Nyuma ya selile ifatwa na alkali, antion ya alkoxy ikozwe mu gucikamo hydroxyl Itsinda rishobora kongeramo oxide yo kugabanya hydroxyProppopyl selile; Irashobora kandi guhuza na methyl chloride kugirango itange methyl selile. HydroxyPropyl Methylcellse ikorwa mugihe ibisubizo byombi bikozwe icyarimwe.

Gukoresha:

Gukoresha hydroxyproppopyl methylcellse isa nizindi bahanga ba selire. Ikoreshwa cyane cyane nkuwatatanye, ihagarika, Thickener, Emulsifuer, stabilizer no kumemeka mumirima itandukanye. Birasumba abandi bahanganye na selile ukurikije ibyokuntu, bidashoboka, gukorera mu mucyo hamwe na enzyme.

Mu biribwa n'inganda za farumasi, ikoreshwa nk'inyongera. Ikoreshwa nk'ingirakamaro, umubyibushye, ikwirakwizwa, emollient, stabilizer na emalisiier. Ntabwo ifite uburozi, ntagaciro kimubiri, kandi nta mpinduka za metabolike.

Byongeye kandi, HPMC ifite ibyifuzo muri synthekique resin polymeiriotariation, peteroli, ceramics, impapuro, gutontoma, guhuza, ibikoresho byo kubaka.
