1. Imico itandukanye
Hydroxypropyl methylcellulose: ifu yera cyangwa yera yera ya fibrous cyangwa ifu ya granular, ikaba itandukanye na selile zitandukanye zidafite ionic selile. Nibice bya sintetike, idakora, polymer ya viscoelastic.
Hydroxyethyl selile: Nibintu bitari ionic soluble selulose ethers.
2. Gukoresha bitandukanye
Hydroxypropyl methylcellulose: Ikoreshwa nkibyimbye, ikwirakwiza kandi igahindura inganda mu nganda, kandi ifite ubwuzuzanye bwiza mumazi cyangwa kumashanyarazi. Nkukuraho irangi; nk'ikwirakwizwa mu musaruro wa chloride polyvinyl, nicyo gikorwa nyamukuru gifasha mugutegura PVC hakoreshejwe polymerisation ihagarikwa; ikoreshwa kandi cyane mu mpu, ibicuruzwa, impapuro, kubungabunga imbuto n'imboga n'inganda.
Hydroxyethyl selulose: ikoreshwa nkibikoresho bifata neza, bifata imiti igabanya ubukana, ikwirakwiza, emulifisiyeri na stabilisateur ikwirakwiza, n'ibindi. n'ubuvuzi.
3. Ibisubizo bitandukanye
Hydroxypropyl methylcellulose: Ntishobora gukemuka muri Ethanol yuzuye, ether, na acetone; irabyimba mumazi asobanutse cyangwa yoroheje ya colloidal mumazi akonje.
Hydroxyethyl selulose: ifite imiterere yo kubyimba, guhagarika, guhuza, kwigana, gutatanya, no kugumana ubushuhe. Ibisubizo bifite ubunini butandukanye burashobora gutegurwa. Ifite umunyu mwiza udasanzwe kuri electrolytite.
Hydroxypropyl methylcellulose (HPMC) Imiterere yumubiri na chimique:
1. Kugaragara: MC ni umweru cyangwa hafi ya fibrous yera cyangwa ifu ya granular, nta mpumuro nziza.
2. Ibyiza: MC hafi yo kutaboneka muri Ethanol yuzuye, ether na acetone. Iratatana kandi ikabyimba vuba mumazi ashyushye kuri 80 ~ 90 and, igashonga vuba nyuma yo gukonja. Igisubizo cyamazi kirahagaze neza mubushyuhe bwicyumba kandi gishobora kuza mubushyuhe bwinshi, kandi gel irashobora guhinduka hamwe nigisubizo hamwe nubushyuhe. Ifite ubuhehere buhebuje, gutatanya, gufatana, kubyimba, emulisile, kubika amazi hamwe no gukora firime, ndetse no kudasiga amavuta. Filime yakozwe ifite ubukana buhebuje, guhinduka no gukorera mu mucyo. Kuberako itari ionic, irashobora guhuzwa nizindi emulisiferi, ariko biroroshye gushiramo umunyu kandi igisubizo gihamye murwego rwa PH2-12.
3. Ubucucike bugaragara: 0.30-0.70g / cm3, ubucucike buri hafi 1,3g / cm3.
2. Uburyo bwo gusesa:
Ibicuruzwa bya MC byongewemo mumazi, bizateranya hanyuma bigashonga, ariko uku gusesa biratinda cyane kandi biragoye.Uburyo butatu bwo gusesa burasabwa, kandi uyikoresha arashobora guhitamo uburyo bworoshye ukurikije uko ikoreshwa:
1. Uburyo bwamazi ashyushye: Kubera ko MC idashonga mumazi ashyushye, MC irashobora gukwirakwizwa neza mumazi ashyushye mugihe cyambere. Iyo bimaze gukonjeshwa, uburyo bubiri busanzwe busobanurwa gutya:
1). Shira amazi asabwa muri kontineri hanyuma ubishyuhe kugeza kuri 70 ° C. Buhoro buhoro ongeramo MC mubitindiganya buhoro, tangira kureremba hejuru yamazi, hanyuma buhoro buhoro ukora ibishishwa, hanyuma ukonje ibishishwa munsi yuburakari.
2). Ongeramo 1/3 cyangwa 2/3 byamazi asabwa muri kontineri hanyuma ubishyuhe kuri 70 ℃. Kurikiza uburyo bwa 1) gutatanya MC kugirango utegure amazi ashyushye; hanyuma shyiramo amazi asigaye cyangwa amazi yubukonje mumazi ashyushye, shyira imvange nyuma yo gukurura.

3. Intego:
Iki gicuruzwa gikoreshwa cyane mubwubatsi, ibikoresho byubwubatsi, impuzu zitatanye, impapuro zometseho, inyongeramusaruro za polymerisiyonike, kuvanaho amarangi, uruhu, wino, impapuro, nibindi nkibibyimbye, ibifunga, ibikoresho bigumana amazi, abakozi bakora firime, ibicuruzwa, nibindi. . .
Imiterere yumubiri na chimique ya methyl selulose (MC):
3. Kugaragara: MC ni umweru cyangwa hafi ya fibrous yera cyangwa ifu ya granular, nta mpumuro nziza.
Ibyiza: MC hafi yo kudashonga muri Ethanol yuzuye, ether na acetone. Iratatana kandi ikabyimba vuba mumazi ashyushye ya 80 ~ 90> ℃, igashonga vuba nyuma yo gukonja. Umuti wamazi urahagaze neza mubushyuhe busanzwe kandi urashobora kuza mubushyuhe bwinshi, kandi gel irashobora guhinduka hamwe nigisubizo hamwe nubushyuhe. Ifite ubuhehere buhebuje, gutatanya, gufatana, kubyimba, emulisile, kubika amazi hamwe no gukora firime, ndetse no kudasiga amavuta. Filime yakozwe ifite ubukana buhebuje, guhinduka no gukorera mu mucyo.

1.Ubucucike bugaragara: 0.30-0.70g / cm3, ubucucike ni 1,3g / cm3.
Kugera. Uburyo bwo gusesa:
MC> Igicuruzwa cyongewemo mumazi, bizateranya hanyuma bigashonga, ariko uku gusesa biratinda cyane kandi biragoye. Uburyo butatu bukurikira bwo guseswa burasabwa, kandi abayikoresha barashobora guhitamo uburyo bworoshye ukurikije imikoreshereze:
1. Uburyo bwamazi ashyushye: Kubera ko MC idashonga mumazi ashyushye, MC irashobora gukwirakwizwa neza mumazi ashyushye mugihe cyambere. Iyo bimaze gukonjeshwa, uburyo bubiri busanzwe busobanurwa gutya:
1). Shira amazi asabwa muri kontineri hanyuma ubishyuhe kugeza kuri 70 ° C. Buhoro buhoro ongeramo MC mubitindiganya buhoro, tangira kureremba hejuru yamazi, hanyuma buhoro buhoro ukora ibishishwa, hanyuma ukonje ibishishwa munsi yuburakari.
2). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri hanyuma ubishyuhe kuri 70 ° C. Kurikiza uburyo muri 1) gutatanya MC kugirango utegure amazi ashyushye; hanyuma shyiramo amazi asigaye cyangwa amazi yubukonje mumazi ashyushye, shyira imvange nyuma yo gukurura.
Uburyo bwo kuvanga ifu: kuvanga byumye byifu ya MC hamwe nubunini cyangwa bunini bwibindi bikoresho byifu kugirango ubisarangane byuzuye, hanyuma wongeremo amazi yo kubishonga, hanyuma MC irashobora gushonga nta agglomeration.
3. Noneho MC nayo irashobora gushonga neza.
Bitanu. Intego:
Iki gicuruzwa gikoreshwa cyane mubwubatsi, ibikoresho byubwubatsi, impuzu zitatanye, impapuro zometseho, inyongeramusaruro za polymerisiyonike, kuvanaho amarangi, uruhu, wino, impapuro, nibindi nkibibyimbye, ibifunga, ibikoresho bigumana amazi, abakozi bakora firime, ibicuruzwa, nibindi. . .
1. Ikoreshwa nka binder muri plaster, plaster, ifu yuzuye cyangwa ibindi bikoresho byubwubatsi kugirango utezimbere kandi wongere igihe cyo gukora. Irashobora gukoreshwa mugushiraho amabati yubutaka, marble, gushushanya plastike, kongera paste, kandi birashobora no kugabanya urugero rwa sima. Amazi yo kubika amazi ya HPMC abuza gutemba guturika bitewe no gukama vuba nyuma yo kubisaba, kandi bikongerera imbaraga nyuma yo gukomera.

8. Inganda zimiti: ibikoresho byo gutwikira; ibikoresho bya firime; kugenzura igipimo cya polymer ibikoresho byo gutegura-kurekura buhoro; stabilisateur; guhagarika abakozi; ibinini bya tablet; umubyimba. Ibyangiza ubuzima: iki gicuruzwa gifite umutekano kandi ntigifite uburozi, kandi gishobora gukoreshwa nk'inyongeramusaruro y'ibiryo, Nta bushyuhe, nta kurakara ku ruhu no mu mucyo. Mubisanzwe bifatwa nkaho bifite umutekano (FDA1985), kwemererwa gufata buri munsi ni 25mg / kg (FAO / OMS 1985), kandi ibikoresho byo gukingira bigomba kwambara mugihe cyo gukora.
Ingaruka ku bidukikije: Irinde guterera bidatinze gutera umwanda uhumeka.
Ibyago byumubiri nubumara: Irinde guhura ninkomoko yumuriro, kandi wirinde ko habaho ivumbi ryinshi ahantu hafunze kugirango wirinde ingaruka ziturika.
Iki kintu mubyukuri gikoreshwa gusa nkikibyimbye, kitari cyiza kuruhu.
