Agaciro k'ubushyuhe bwa gel muri hydroxypropyl methylcellulose

1. Ubushyuhe bwa jeli (umuti wa 0.2%) 50-90°C.

2. Ishongesha mu mazi no mu gice kinini cya polar c hamwe n'igipimo gikwiye cya ethanol/amazi, propanol/amazi, dichloroethane, nibindi, ntishongesha muri ether, acetone, ethanol yuzuye, kandi ikabyimba ikagera mu gisubizo cya colloidal cy'amazi akonje cyangwa gisobanutse neza. Igisubizo cy'amazi gifite imikorere yo hejuru, ubwisanzure bwinshi kandi gihamye.

3. HPMC ifite imiterere yo gushyushya. Umuti w'amazi ushyushye kugira ngo ukore gel hanyuma irashonga, hanyuma igashonga nyuma yo gukonja. Ubushyuhe bwo gushyushya butandukanye buratandukanye. Gushonga biratandukana bitewe n'ubushyuhe. Uko ubushyuhe bugabanuka, niko gushonga kuba kunini. Ibisobanuro bitandukanye bya HPMC bigira itandukaniro mu miterere yabyo, kandi gushonga kwa HPMC mu mazi ntibigira ingaruka ku gaciro ka pH.

4. Ingano y'uduce: Igipimo cyo gusohora mesh 100 kiri hejuru ya 98.5%. Ubucucike bw'ibice: 0.25-0.70g/ (ubusanzwe hafi 0.4g/), uburemere bwihariye 1.26-1.31. Ubushyuhe bwo guhindura ibara: 180-200°C, ubushyuhe bwa karuboni: 280-300°C. Agaciro ka methoxyl kari hagati ya 19.0% na 30.0%, naho agaciro ka hydroxypropyl kari hagati ya 4% na 12%. Ubushyuhe (22°C, 2%) 5～200000mPa .s. Ubushyuhe bwa Gel (0.2%) 50-90°C

5. HPMC ifite imiterere yo gukurura, gusohora umunyu, kudahinduka kwa PH, kubika amazi, kudahinduka kw'ibipimo, ubushobozi bwiza bwo gukora filime, uburyo bwinshi bwo kudahangana na enzymes, gukwirakwira no guhuza.
