I-Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC

1) Ukubukeka: I-HPMC iyi-nonionic cellulose ether, impushana emhlophe empunga-emhlophe noma i-granule, engenaphunga futhi ayinambitheki, encibilika emanzini abandayo, i-glacial acetic acid, i-ethanol, i-methanol ne-propylene glycol, encibilika kancane ku-acetone kuye ngezinga lokushintshwa, cishe ayincibiliki emanzini ashisayo, i-ethylene glycol ne-toluene. I-HPMC incibilika engxubeni ye-methanol engu-10% kanye ne-90% ye-methylene chloride ukuze yakhe izixazululo ze-colloidal.
2) Isixazululo se-HPMC sinomsebenzi ongaphezulu, ukukhanya okuphezulu, nokusebenza okuzinzile. Uma kushiswa ngezinga elithile lokushisa, ikhambi liyaguqubala noma lakha ijeli elithambile. Nokho, ikhambi liphinde licace ngemva kokupholisa. Izinhlobo ezahlukene ze-HPMC zinamazinga okushisa ahlukene e-gelation. I-solubility iyahlukahluka ngokuya nge-viscosity. Lapho i-viscosity iphansi, i-solubility ephakeme enayo. Izinhlobo ezahlukene ze-HPMC zihlukile kwezinye izakhiwo futhi ukuncibilika kwazo emanzini akuthintwa i-pH.
3) Osayizi bezinhlayiya: Izinga lokuphasa elingu-100% ku-80 mesh.
4) Ukuminyana okubonakalayo: 0.25-0.70 g/mL (imvamisa cishe u-0.5 g/mL), ukuminyana okuthile 1.26-1.31mL.
5) Ukushisa kokushintsha kombala: 190-200 ° C; Ukushisa kwe-Carbonization: 280-300 ° C.
I-6) Ukungezwani kwendawo: 42-56 dyn / cm (2% isixazululo samanzi).
7) Okuqukethwe okuphezulu kwe-methoxy ku-HPMC, izinga lokushisa eliphansi le-gelation, kanye nokuncibilika okuphezulu emanzini nangaphezulu.
8) I-HPMC inezinye izici, isibonelo, ukujiya kwempahla, ukuzinza kwe-pH, ukugcinwa kwamanzi, indawo enhle kakhulu yokwenza ifilimu, ukuhlakazeka okuhle nekhono lokunamathela.
