HPMC Hydroxypropyl Methyl Cellulose CAS No.9004-65-3
IiNkcazo zeeMveliso
- IHydroxypropyl Methyl Cellulose (HPMC) yi-agent etyebisayo, iindidi ezibalulekileyo kwi-non-ionic cellulose exutywe ne-ether.
- IHydroxypropyl Methyl Cellulose (HPMC) luhlobo lweselulosi oluphuma kunye nokusetyenziswa kwayo kuye kwanda ngokukhawuleza kwiminyaka yakutshanje. I-ether engeyiyo ionic cellulose exutywe ne-ether eyenziwe kwikotoni esulungekileyo ngoluhlu lweempendulo usebenzisa i-propylene oxide kunye ne-methyl chloride njengee-etherification agents emva konyango lwe-alkalization. Iimpawu zayo zihluke ngomlinganiselo womxholo we-methoxy kunye nomxholo we-hydroxypropyl.
Uphawu lweMveliso
- Ukunyamezela ityuwa;
- ukuzinza kwe-pH;
- Ukugcinwa kwamanzi;
- Uzinzo lweDimensional;
- Iipropati ezigqwesileyo zokwenza ifilimu;
- Ukuchasana kwe-enzyme ebanzi, ukusasazeka kunye nokubambisana.
