1. Ubushyuhe bwa gel (0.2% igisubizo) 50-90 ° C.
2. Gushonga mumazi hamwe na polar c nyinshi hamwe nigipimo gikwiye cya Ethanol / amazi, propanol / amazi, dichloroethane, nibindi, bidashonga muri ether, acetone, etanol yuzuye, hanyuma bikabyimba neza cyangwa bituje gato mumazi akonje ya colloidal.Igisubizo cyamazi gifite ibikorwa byubuso, gukorera mu mucyo no gukora neza.
3. HPMC ifite umutungo wa gelasique.Igicuruzwa cyamazi yo mumazi arashyuha kugirango akore gel hanyuma agwe, hanyuma ashonga nyuma yo gukonja.Ubushyuhe bwa gelation bwibisobanuro bitandukanye buratandukanye.Gukemura biratandukanye nubwiza.Hasi ya viscosity, niko gukomera.Ibisobanuro bitandukanye bya HPMC bifite itandukaniro runaka mumiterere yabyo, kandi iseswa rya HPMC mumazi ntabwo rihindurwa nagaciro ka pH.
4. Ingano y'ibice: igipimo cya mesh 100 kirenze 98.5%.Ubucucike bwinshi: 0.25-0.70g / (mubisanzwe hafi 0.4g /), uburemere bwihariye 1.26-1.31.Ubushyuhe bwo guhindura ibara: 180-200 ° C, ubushyuhe bwa karubone: 280-300 ° C.Agaciro metoxyl kangana na 19.0% kugeza 30.0%, naho hydroxypropyl agaciro kiva kuri 4% kugeza 12%.Ubushuhe (22 ° C, 2%) 5 ～ 200000mPa .s.Ubushyuhe bwa gel (0.2%) 50-90 ° C.
