1. Heerkulka jel (0.2% xal) 50-90°C.
2. Ku milmay biyaha iyo inta badan polar c iyo saamiga ku habboon ethanol/biyaha, propanol/biyaha, dichloroethane, iwm., aan milmin ee ether, acetone, ethanol dhammaystiran, oo barara si cad ama wax yar u turbid xal kolloidal biyo qabow. Xalka aqueous wuxuu leeyahay dhaqdhaqaaqa dusha sare, daahfurnaanta sare iyo waxqabadka xasilloon.
3. HPMC waxay leedahay hantida gelation kulaylka. Xalka aqueous alaabta ayaa la kululeeyaa si ay u sameeyaan jel oo soo da'aya, ka dibna milaan qaboojinta ka dib. Heerkulka gelation ee tilmaamo kala duwan ayaa ka duwan. Solubility wuxuu ku kala duwan yahay viscosity. Maqnaanshaha hoose, waa ka sii weynaanta milanka. Tilmaamaha kala duwan ee HPMC waxay leeyihiin kala duwanaansho gaar ah hantidooda, iyo kala dirida HPMC ee biyaha ma saamayso qiimaha pH.
4. Cabbirka qaybta: 100 mesh heerka baasasku wuu ka weyn yahay 98.5%. Cufnaanta buk: 0.25-0.70g/ (badanaa ku dhawaad 0.4g/), cufnaanta gaarka ah 1.26-1.31. heerkulka midabka: 180-200C, heerkulka carbonization: 280-300C. Qiimaha methoxyl wuxuu u dhexeeyaa 19.0% ilaa 30.0%, iyo qiimaha hydroxypropyl wuxuu u dhexeeyaa 4% ilaa 12%. Viscosity (22°C, 2%) 5～200000mPa .s. Heerkulka jelka (0.2%) 50-90°C
5. HPMC waxay leedahay sifooyinka awoodda dhumucda, dheecaanka milixda, xasiloonida PH, haynta biyaha, xasiloonida cabbirka, hantida samaynta filim heer sare ah, caabbinta enzyme ballaaran, kala-baxsanaan iyo isku-duubnaan.
