Hydroxypropyl methylcellulose waa eter cellulose aan-ionic ahayn oo laga sameeyay maadada polymer-ka dabiiciga ah (suuf) cellulose iyada oo loo marayo nidaamyo kiimiko oo taxane ah. Waa budo cad oo aan ur lahayn, oo aan dhadhamin kuna barara xal kolloidal cad ama waxoogaa daruuro leh oo biyo qabow ah. Waxay leedahay dhumuc, xidhidh, kala firdhisan, emulsifying, filim samaynta, laalista, adsorbing, gelling, dusha firfircoon, qoyaan-hayntiisa iyo sifooyinka kolloid ilaalinta.
Tilmaamaha iyo faa'iidooyinka kiimikaad maalinlaha ah ee cellulose cellulose:
1. Cuncun hooseeya, heerkulka sare iyo kuwa aan sunta ahayn;
2. Degganaanshaha qiimaha pH ballaaran, kaas oo hubin kara xasilloonidiisa inta u dhaxaysa qiimaha pH 6-10;
3. Kobcinta qaboojinta;
4. Kordhi xumbo, deji xumbo, hagaaji dareenka maqaarka;
5. Si wax ku ool ah u wanaaji dheecaanka nidaamka.
Baaxadda codsiga maalinlaha ah ee cellulose cellulose kiimikaad:
Loo isticmaalo shaambo, maydhista jirka, saabuunta saxanka, saabuunta dharka, jel, qaboojiyaha timaha, alaabada habaynta, daawada cadayga, candhuufta, biyaha xumbo-cayaaraha.
Doorka darajada kiimikada maalinlaha ahcellulose HPMC:
Inta badan loo isticmaalo dhumucdiisuna, xumbo, emulsification deggan, kala firdhiso, adhesion, hagaajinta filimada-samaynta iyo guryaha-haysashada biyaha, wax soo saarka viscosity sare waxaa loo isticmaalaa dhumucdiisuna, wax soo saarka hoose ee viscosity waxaa inta badan loo isticmaalaa kala firidhsan hakinta iyo film-samaynta.
Tignoolajiyada HPMC ee fasalka cellulose kiimikaad maalinle ah:
Qadarka hydroxypropyl methylcellulose ee ku habboon warshadaha kiimikada ee maalinlaha ah waa guud ahaan
