Ibisubizo byamazi biragaragara hejuru. Gukorera mu mucyo mwinshi, imikorere ihamye, gel ubushyuhe bwibicuruzwa bifite ibisobanuro bitandukanye
Bitandukanye, solubilité ihinduka hamwe nubukonje, uko ubukonje bugenda bugabanuka, niko bigenda byiyongera cyane, imikorere yuburyo butandukanye bwa hydroxypropyl methylcellulose (HPMC) ifite itandukaniro runaka, iseswa rya hydroxypropyl methylcellulose (HPMC) mumazi ntabwo bigira ingaruka kumikorere ya PH .
88. Hamwe no kugabanuka kwibintu bya vitamine, ingingo ya gel iriyongera, amazi agabanuka, kandi ibikorwa byubuso bwa hydroxypropyl methylcellulose (HPMC) nabyo biragabanuka.
09.
Bitatu, hydroxypropyl methylcellulose (HPMC) ibiranga:
Igicuruzwa gihuza ibintu byinshi byumubiri nubumashini kugirango bibe ibicuruzwa bidasanzwe hamwe nibikoreshwa byinshi, kandi ibintu bitandukanye nibi bikurikira:
(1) Kubika amazi: Irashobora gufata amazi hejuru yububiko nk'imbaho ya sima y'urukuta n'amatafari.
(2) Gukora firime: Irashobora gukora firime ibonerana, ikomeye kandi yoroshye hamwe na peteroli nziza cyane.
.
.
.
.
(7) Kurinda colloid: irashobora kubuza ibitonyanga nuduce guhurira hamwe.
.
.
.
(11) Acide-ishingiro ihamye: ikwiriye gukoreshwa murwego rwa PH3.0-11.0.
(12) Uburyohe kandi butagira impumuro nziza, ntibiterwa na metabolism; ikoreshwa nkibiryo byongera ibiyobyabwenge, ntabwo bizahinduka mubiryo kandi ntibizatanga karori.
4. Hydroxypropyl methylcellulose (HPMC) uburyo bwo gusesa:
Iyo ibicuruzwa bya hydroxypropyl methylcellulose (HPMC) byongewe kumazi mu buryo butaziguye, bizahuza hanyuma bigashonga, ariko uku gusesa biratinda cyane kandi biragoye. Hano hari uburyo butatu bwatanzwe bwo gusesa hepfo, kandi abakoresha barashobora guhitamo uburyo bworoshye ukurikije imikoreshereze yabo:
1. ikurikira:
1). Shira amazi asabwa muri kontineri hanyuma uyashyuhe kugeza kuri 70 ° C. Buhoro buhoro ongeramo hydroxypropyl methylcellulose (HPMC) munsi yo gukurura buhoro, hydroxypropyl methylcellulose (HPMC) itangira kureremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibishishwa, ikonjesha ibishishwa munsi.
2). Shyushya 1/3 cyangwa 2/3 (umubare ukenewe) w'amazi muri kontineri hanyuma ubishyuhe kugeza kuri 70 ° C. Ukurikije uburyo bwa 1), kwirakwiza hydroxypropyl methylcellulose (HPMC) kugirango utegure amazi ashyushye Noneho shyiramo amazi asigaye cyangwa amazi yubukonje asigaye muri kontineri, hanyuma ushyiremo hydroxypropyl methylcellulose (HPMC) amazi ashyushye yavuzwe hejuru kuri amazi akonje, hanyuma ukangure, hanyuma ukonje imvange.
3). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri hanyuma ubishyuhe kuri 70 ° C. Ukurikije uburyo bwa 1), kwirakwiza hydroxypropyl methylcellulose (HPMC) kugirango utegure amazi ashyushye; Umubare usigaye wamazi akonje cyangwa urubura noneho wongewe kumazi ashyushye hanyuma imvange ikonjeshwa nyuma yo gukurura.
2. . 3. Muri iki gihe, hydroxypropyl methylcellulose (HPMC) nayo irashobora gushonga neza.
5. Gukoresha cyane hydroxypropyl methylcellulose (HPMC):
Hydroxypropyl methylcellulose (HPMC) irashobora gukoreshwa nkibibyimbye, bitatanya, emulisiferi hamwe nogukora firime. Ibicuruzwa byacyo byo mu rwego rwinganda birashobora gukoreshwa mumiti ya buri munsi, ibikoresho bya elegitoroniki, ibisigazwa byubukorikori, kubaka no gutwikira.
1. Guhagarika polymerisation:
Mu gukora ibisigisigi bya sintetike nka polyvinyl chloride (PVC), chloride polyvinylidene nizindi copolymer, polymerisation ihagarikwa ikoreshwa cyane kandi irakenewe kugirango ihagarikwa rya monomers hydrophobique mumazi. Nka polymer ikabura amazi, hydroxypropyl methylcellulose (HPMC) ifite ibikorwa byiza byubutaka kandi ikora nkibikoresho byo gukingira indwara, bishobora gukumira neza kwegeranya uduce duto twa polymer. Ikigeretse kuri ibyo, nubwo hydroxypropylmethylcellulose (HPMC) ari polymer yamazi yamazi, nayo irashobora gushonga gato muri monomers hydrophobique kandi ikongerera ubukana bwa monomers ikomokamo uduce twa polymeric, kuburyo ishobora gutanga polymers nubushobozi buhebuje bwo gukuraho monomer zisigaye. no kongera kwinjiza plastiseri.
2. Mugutegura ibikoresho byubwubatsi, hydroxypropyl methylcellulose (HPMC) irashobora gukoreshwa kuri:
1). Ibikoresho bifata kandi bifata ibyuma bya gypsumu;
2). Guhambira amatafari ashingiye kuri sima, amabati n'imfatiro;
3). Amashanyarazi ashingiye kuri plaque;
4). Isima ishingiye kuri sima;
5). Muri formula yo gusiga irangi no gukuraho amarangi.
