Hydroxypropyl Methyl Cellulose HPMC Transparency

Ukucaca okuphezulu kunye nokusebenza okuzinzileyo.

I-HPMC inepropati ye-thermal gelation. Imveliso yesisombululo se-aqueous ishushu ukuze yenze i-gel kunye ne-precipitates, kwaye idibanise emva kokupholisa. Ukushisa kwe-gelation yeenkcukacha ezahlukeneyo kuyahluka. Ukunyibilika kuyahluka kunye ne-viscosity. I-viscosity ephantsi, i-solubility enkulu. Iimpawu ezahlukeneyo ze-HPMC zineeyantlukwano ezithile kwiipropati zabo, kwaye ukuchithwa kwe-HPMC emanzini akuchatshazelwa yixabiso le-pH.

Ubungakanani besuntswana: Ireyithi yokupasa ngemesh eyi-100 inkulu kune98.5%.

Ubushushu bejeli (0.2%) ngu 50-90°C.

I-HPMC ineempawu zokukwazi ukutyeba, ukukhutshwa kwetyuwa, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, ipropathi ebalaseleyo yokwenza ifilimu kunye noluhlu olubanzi lokuxhathisa i-enzyme, ukusabalalisa kunye nokubambisana.
