Imiti ya buri munsi hydroxypropyl methylcellulose HPMC

Hydroxypropyl methylcellulose ni ether idafite ionic selulose ether ikozwe mubintu bisanzwe bya polymer (pamba) selile ikoresheje uburyo bwa chimique. Ni ifu yera idafite impumuro nziza, idafite uburyohe bwabyimbye mubisubizo bisobanutse cyangwa bicu byoroheje bya colloidal mumazi akonje. Ifite umubyimba, guhambira, gutatanya, kwigana, gukora firime, guhagarika, adsorbing, gell, hejuru yubutaka, kugumana ubushuhe no kurinda colloid.

 

Ibiranga ibyiza bya selile ya buri munsi ya selile HPMC:

1. Kurakara gake, ubushyuhe bwinshi kandi butari uburozi;

2. Umugari mugari wa pH agaciro, ushobora kwemeza ko uhagaze murwego rwa pH agaciro 6-10;

3. Kongera imiterere;

4. Kongera ifuro, guhagarika ifuro, kunoza uruhu;

5. Kunoza neza imikorere ya sisitemu.

Ingano yo gukoresha imiti ya selile ya buri munsi selile HPMC:

Ikoreshwa muri shampoo, koza umubiri, isabune yisahani, kumesa, kumesa, gel, kogosha umusatsi, ibicuruzwa byububiko, umuti wamenyo, amacandwe, amazi yikinisho.

Uruhare rwimiti ya buri munsiselile HPMC:

Ahanini bikoreshwa mubyimbye, kubira ifuro, emulisiyasi ihamye, gutatanya, gufatira hamwe, kunoza imitunganyirize ya firime no kugumana amazi, ibicuruzwa byijimye cyane bikoreshwa mubyimbye, ibicuruzwa bidafite ubukana buke bikoreshwa cyane cyane muguhagarika no guhagarika firime.

Imiti ya buri munsi ya selile ya selile HPMC:

Ingano ya hydroxypropyl methylcellulose ikwiranye ninganda zimiti ya buri munsi muri rusange
