Kedu ihe na-emetụta njigide mmiri nke hydroxypropyl methylcellulose?
Njide mmiri nke ngwaahịa HPMC hydroxypropyl methylcellulose n'onwe ya na-emetụtakarị ihe ndị a:
1. Homogeneity nke cellulose ether HPMC
Ndị otu HPMC methoxy na hydroxypropoxy a na-emeghachi omume na-ekesa nke ọma ma nwee njigide mmiri dị elu.
2. Cellulose ether HPMC thermal gel okpomọkụ
Dị elu okpomọkụ nke thermal conductive gel, nke dị elu nke njide mmiri;N'aka nke ọzọ, na-ebelata ọnụ ọgụgụ njide mmiri.
3. Viscosity nke cellulose ether HPMC
Mgbe viscosity nke HPMC na-abawanye, njigide mmiri na-abawanye;mgbe viscosity rutere n'ogo ụfọdụ, mmụba nke njide mmiri na-eme ka ọ dị nro.
