Niki HydroxypropylMethylCellulose

Hydroxypropyl Methylcellulose (HPMC) ni ether ya selile idafite ionic ikomoka kuri selile naturel. Ihinduranya binyuze mu guhindura imiti ya selile, ubusanzwe iboneka mu biti cyangwa ibiti by'ipamba. HPMC ikoreshwa cyane mu nganda zitandukanye bitewe nuburyo butandukanye kandi bukoreshwa.

Imiterere ya shimi:

• HPMC igizwe numugongo wa selile hamwe na hydroxypropyl hamwe na methyl insimburangingo ifatanye nitsinda rya hydroxyl yibice bya glucose. Urwego rwo gusimbuza (DS) rwerekana impuzandengo ya hydroxypropyl na methyl mumatsinda ya glucose murwego rwa selile. Imiterere yimiti ya HPMC itanga ibintu byihariye nko gukama amazi, ubushobozi bwo gukora firime, no guhindura viscosity.

Ibiranga n'ibiranga:

1. Amazi meza: HPMC irashobora gushonga mumazi akonje, amazi ashyushye, hamwe na solge zimwe na zimwe nka methanol na Ethanol. Gukemura biterwa nibintu nkurwego rwo gusimbuza, uburemere bwa molekile, nubushyuhe.
2. Igenzura rya Viscosity: HPMC ibisubizo byerekana imyitwarire ya pseudoplastique cyangwa shear-inanura, aho ububobere bugabanuka hamwe no kongera umuvuduko wogosha. Irakoreshwa cyane nkibyimbye, ihindura imvugo, hamwe na stabilisateur muburyo butandukanye kugirango igenzure ububobere no kunoza imiterere.
3. Imiterere ya firime: HPMC irashobora gukora firime zibonerana cyangwa zisobanutse iyo zumye. Izi firime zifite imiterere myiza, ihindagurika, hamwe na barrière, bigatuma HPMC ibereye gutwikirwa, firime, hamwe nibinini bya farumasi.
4. Kuvomera no kubyimba: HPMC ifitanye isano n’amazi kandi irashobora gukurura no kugumana amazi menshi. Iyo ikwirakwijwe mu mazi, HPMC itanga amazi kugirango ikore geles ifite imitekerereze ya pseudoplastique, ituma amazi agumana kandi agakora neza.
5. Inertness ya chimique: HPMC ni inert ya chimique kandi ntabwo ikora reaction yimiti mugihe cyo gutunganya no kubika neza. Irahujwe nurwego runini rwibindi bintu byongeweho byongeweho.

Porogaramu:

• Imiti ya farumasi: Nibyingenzi mubinini, capsules, amavuta, guhagarika, hamwe no kugenzura-kurekura.
• Ubwubatsi: Ongeraho mumatafari ya tile, minisiteri, gushushanya, plasta, hamwe no kwishyira hamwe kugirango utezimbere amazi, gukora, hamwe no gufatira hamwe.
• Irangi hamwe na Coatings: Thickener, stabilisateur, hamwe nogukora firime mugushushanya kwa latex, polymerisiyasi ya emulsion, hamwe na coatings kugirango bigabanye ububobere no kuzamura imiterere ya firime.
• Ibiribwa n'ibinyobwa: Umuti wibyibushye, emulisiferi, na stabilisateur mu isosi, imyambarire, isupu, deserte, n'ibinyobwa kugirango utezimbere kandi uhamye.
• Kwitaho kwawe no kwisiga: Thickener, agent ahagarika, hamwe nuwashizeho firime muri shampo, kondereti, cream, amavuta yo kwisiga, hamwe na masike kugirango azamure imikorere nibikorwa byiza.

Hydroxypropyl Methylcellulose (HPMC) ihabwa agaciro kubera byinshi, umutekano, ndetse no gukora neza mubikorwa bitandukanye byinganda, bigira uruhare mugukoresha kwinshi mubikorwa byinshi.
