Hydroxypropyl Methyl Cellulose HPMC Transparency

Kujeka kwepamusoro uye kushanda kwakagadzikana.

HPMC ine pfuma ye thermal gelation.Chigadzirwa chine aqueous solution chinopisa kuti chigadzire gel uye chinonaya, uye chinozonyungudika mushure mekutonhora.Iyo tembiricha yegelation yemhando dzakasiyana dzakasiyana.Solubility inosiyana ne viscosity.Iyo yakaderera viscosity, iyo yakakura solubility.Madiro akasiyana eHPMC ane mimwe misiyano mumidziyo yavo, uye kunyungudika kweHPMC mumvura hakukanganiswe nehukoshi hwepH.

Particle size: 100 mesh pass rate yakakura kupfuura 98.5%.

Hukuru density: 0.25-0.70g/ (kazhinji anenge 0.4g/), chaiyo giravhiti 1.26-1.31.

Discoloration tembiricha: 200-200 ° C,

Carbonization tembiricha: 280-300°C.

Methoxy kukosha 19.0% kusvika 30.0%,

Hydroxypropyl kukosha 4% kusvika 12%.

Viscosity (22℃, 2%) 5～200000mPa.s.

Tembiricha yegel (0.2%) i50-90°C.

HPMC ine hunhu hwekukora kugona, kubuda munyu, kugadzikana kwePH, kuchengetedza mvura, kugadzikana kwedimensional, yakanakisa kugadzira firimu pfuma uye kuwanda kwekudzivirira kwe enzyme, dispersibility uye kubatana.
