Ntchito yomanga fakitale ya HPMC
1. MODCELL Hydroxypropyl Methyl Cellulose(HPMC), ndi ma non-ionic cellulose ethers opangidwa kuchokera ku cellulose yachilengedwe yapamwamba kwambiri (thonje woyeretsedwa) kudzera muzotsatira zamakemikolo.Ikhoza kusungunuka m'madzi pachiŵerengero chilichonse, max awo, ndende zimadalira mamasukidwe awo.
2. Iwo ali ndi zinthu monga kusungunuka kwa madzi, katundu wosungira madzi, mtundu wosakhala wa ionic, mtengo wokhazikika wa PH, ntchito yapamwamba, kusinthika kwa gelling kuthetsa kutentha kosiyana, kukhuthala, kupanga filimu ya cementation, mafuta opangira mafuta, kukana nkhungu ndi zina.
3. Ndizinthu zonsezi, zimagwiritsidwa ntchito kwambiri pakupanga makulidwe, ma gelling, kuyimitsa kukhazikika, komanso kusunga madzi.
4. Iwo ali zachilendo ndi ofunika gulu thupi ndi mankhwala katundu, malinga ndi kusiyana m'malo digiri ya m'malo gulu ndi digiri kusinthidwa.
5. Pambuyo pobowola pamwamba pake itamwa chinyezi, imatha kusunga chinyezi;
Wopanga ntchito yomanga ya HPMC 1

Mtengo wa HPMCZopangira zokhala ndi zinthu zabwino, zimagwiritsidwa ntchito kwambiri pomanga ngati zomatira matailosi a ceramic, kudzipangira simenti, matope otchinjiriza, pulasitala matope, kukongoletsa kwa putty, gypsum.
HPMC ndi mtundu wa ufa mphira umene ungagwiritsidwe ntchito ngati chowonjezera chakudya, dispersant, emulsifier, suspending wothandizira, thickener, excipient, filler, stabilizer, mafuta kusamva ❖ kuyanika, etc.
➢Nthawi yayitali yotseguka
➢Kukana kwambiri kuterera
➢Kusunga madzi kwambiri
➢Kukwanira kokwanira kumamatira mphamvu
