Hpmc ufa wopanga zipatso za HPMC ufa wa hpmc
Mafotokozedwe Akatundu
HPMC ndi yopanda fungo, yopanda pake, yopanda mphamvu yopanda mphamvu yopangidwa kuchokera ku cellulose yachilengedwe kudzera mu celluul yokhazikika kudzera mu celluuse yosiyanasiyana ya mankhwala ndikukhala ndi ufa woyera ndi kusungunuka kwamadzi abwino. Ili ndi kukulira, kutsatira, kubalalika, emulsiftaute, filimu, kuyimitsidwa, kukhazikika, ndi ma colloud coloction ntchito.

Kugwira nchito
Ndiko kupanga polymer, ma viscoelastic, ma viscoelastic omwe nthawi zambiri amagwiritsidwa ntchito mu ophthalmology monga mafuta, kapena ngati zitsamba kapena zotsatsa mu mankhwala am`kamwa, zomwe nthawi zambiri zimapezeka m'malo osiyanasiyana. Monga chakudya chowonjezera, hydroxypropyl methylcelulose ingagwiritsidwe ntchito mu maudindo otsatirawa: emulsifier, thiCerfair, woyimilira, wolumala wa nyama.
Karata yanchito
Kuphimba ndi chophimba chomwe chimagwiritsidwa ntchito pamtunda wamakoma, nthawi zambiri amatchedwa gawo lapansi. Cholinga chogwiritsira ntchito zofunda zitha kukhala zokongoletsa, zogwira ntchito, kapena zonse ziwiri. Chovala chimawonjezeranso katundu wabwino monga anti-slatterring ndi kusaka, kukula kwake, etc.
