Heerka qurxinta HPMC
Heerka qurxinta HPMC hydroxypropyl methylcellulose waa budo cad ama wax yar oo huruud ah, waana mid aan ur lahayn, aan dhadhamin oo aan sun ahayn. Waxay ku milmi kartaa biyo qabow iyo dareerayaasha organic si ay u sameeyaan xal muuqda oo hufan. Dareeraha biyuhu wuxuu leeyahay dhaqdhaqaaqa dusha sare, daah-furnaan sare, iyo xasillooni xooggan, iyo kala diristeeda biyaha ma saameynayso pH. Waxay leedahay saameyn dhumuc iyo baraf ka hortag ah oo ku jirta shaambooyinka iyo shaambada qubeyska, waxayna leedahay haynta biyaha iyo sameynta aflaanta wanaagsan ee timaha iyo maqaarka. Cellulose (ku dhumucdiisuna) waxay gaari kartaa natiijooyin fiican marka loo isticmaalo shaambooyinka iyo shaambada qubeyska.
Ugu weynMuuqaals
1. Xanaaqa hoose, shaqeynta heerkulka sare;
2. Xasilooni ballaaran oo pH ah, taas oo dammaanad qaadi karta xasilloonideeda inta u dhaxaysa pH 3-11;
3. Kobcinta qaboojinta;
4. Kordhi oo deji xumbo, hagaaji dareenka maqaarka;
5. Dheecaannada habka xalalka.

Codsiga kala duwan ee darajada qurxinta HPMC:
Loo isticmaalo dhaqidda jirka, nadiifiyaha wejiga, kareemka, kareemka, jel, toner, timaha qaboojiyaha, alaabada habaynta, daawada cadayga, dhaqidda afka, biyaha xumbo-cayaaraha. Doorka maalinlaha ah ee fasalka cellulose ee kiimikaad HPMC
Codsiyada la isku qurxiyo, waxaa inta badan loo isticmaalaa dhumucyada la isku qurxiyo, xumbo, emulsification deggan, kala firidhsan, adhesion, samaynta filimada iyo hagaajinta waxqabadka haynta biyaha, wax soo saarka viscosity sare waxaa loo isticmaalaa sida dhumuc, iyo wax soo saarka hoose-viscosity waxaa inta badan loo isticmaalaa joojinta iyo kala firdhisanaan. Sameynta filimada.
Tignoolajiyada heerka isqurxinta ee cellulose HPMC:
