Hydroxypropyl Methyl Cellulose HPMC Hufnaanta

Daah-furnaan sare iyo waxqabad xasilloon.

HPMC waxay leedahay hantida gelation kulaylka.Xalka aqueous sheyga ayaa la kululeeyaa si uu u sameeyo jel oo soo da'o, ka dibna mila marka la qaboojiyo ka dib.Heerkulka gelation ee tilmaamo kala duwan ayaa ka duwan.Solubility wuxuu ku kala duwan yahay viscosity.Maqnaanshaha hoose, ayaa sii weynaan kara milanka.Tilmaamaha kala duwan ee HPMC waxay leeyihiin kala duwanaansho gaar ah oo ku saabsan hantidooda, iyo kala dirida HPMC ee biyaha ma saameynayso qiimaha pH.

Cabbirka qaybta: 100 mesh heerka kaarka mesh wuxuu ka weyn yahay 98.5%.

Cufnaanta buk: 0.25-0.70g/ (badanaa qiyaastii 0.4g/), cufnaanta gaarka ah 1.26-1.31.

heerkulka midabka: 200-200C,

Heerkulka kaarboonaynta: 280-300°C.

Qiimaha methoxy 19.0% ilaa 30.0%,

Hydroxypropyl qiimaha 4% ilaa 12%.

Viscosity (22℃, 2%) 5～200000mPa.s.

Heerkulka jel (0.2%) waa 50-90 ° C.

HPMC waxay leedahay sifooyinka awoodda dhumucda, dheecaanka milixda, xasiloonida PH, haynta biyaha, xasiloonida cabbirka, hantida samaynta filim heer sare ah iyo baaxad ballaadhan oo caabbinta enzyme, kala-baxsanaanta iyo isku xirnaanta.
