Isihluzi seThickener Hydroxypropyl Methyl Cellulose Etere HPMC

I-1) Imbonakalo: I-HPMC yi-ether ye-cellulose e-nonionic, i-white greyish-white powder okanye i-granule, ingenavumba kwaye ayinancanci, i-soluble emanzini abandayo, i-glacial acetic acid, i-ethanol, i-methanol kunye ne-propylene glycol, i-soluble kancinane kwi-acetone ngokuxhomekeke kwiqondo lokutshintshela, ayinyibiliki ngokupheleleyo emanzini ashushu, ethylene glycol kunye netoluene. I-HPMC inyibilika kumxube we-10% ye-methanol kunye ne-90% ye-methylene chloride ukwenza izisombululo ze-colloidal.
2) Isisombululo se-HPMC sinomsebenzi ongaphezulu, ukukhanya okuphezulu, kunye nokusebenza okuzinzileyo. Xa kushushu kwiqondo elithile lobushushu, isisombululo siba ngamafu okanye senze ijeli ehlumayo. Nangona kunjalo, isisombululo siyacaca kwakhona emva kokupholisa. Iindidi ezahlukeneyo ze-HPMC zinobushushu obuhlukeneyo be-gelation. I-solubility iyahluka kunye ne-viscosity. I-viscosity ephantsi, i-solubility ephezulu inayo. Iindidi ezahlukeneyo ze-HPMC zahlukile kwezinye iipropati kwaye ukunyibilika kwazo emanzini akuchatshazelwa yi-pH.
3) Ubungakanani be-particle: 100% izinga lokupasa kwi-80 mesh.
4) Ubuninzi obubonakalayo: 0.25-0.70 g / mL (ngokuqhelekileyo malunga ne-0.5 g / mL), ubuninzi obuthile 1.26-1.31mL.
5) Ubushushu bokutshintsha umbala: 190-200 ° C; Ubushushu beCarbonization: 280-300°C.
I-6) Uxinzelelo lomphezulu: 42-56 dyn / cm (2% isisombululo samanzi).
7) Umxholo ophezulu we-methoxy kwi-HPMC, ubushushu obuphantsi be-gelation, kunye ne-solubility ephezulu emanzini kunye nomsebenzi ongaphezulu.
8) I-HPMC inezinye iimpawu, umzekelo, ukuqina kwepropati, ukuzinza kwe-pH, ukugcinwa kwamanzi, ipropati ebalaseleyo yokwenza ifilimu, ukusabalalisa okulungileyo kunye nokukwazi ukunamathela.
