I-Detergent Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
I-Viscosity ephezuluI-HPMCi-hydroxypropyl methyl celluloseI-ThickenerNge-putty powder:
1) Ukubukeka:I-HPMCi-nonionic cellulose ether, impushana emhlophe empunga-emhlophe noma imbudumbudu, ayinaphunga futhi ayinambitheki, encibilika emanzini abandayo, i-glacial acetic acid, i-ethanol, i-methanol ne-propylene glycol, inyibilika 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, isixazululo siba namafu noma sakha ijeli le-flocculent.Nokho, ikhambi libuye licace futhi 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 ukunyibilika 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.

Imikhiqizo ye-Youngcel ihlanganisa zonke izinhlobo zemikhiqizo ewuketshezi njengezihlanzi zaphansi, okokuhlanza kanye nemikhiqizo yokuwasha izitsha ene-pH phakathi.6- 8
Abancanecelingasetshenziswa njenge-thickener ukulungisa i-rheology yezihlanzi eziwuketshezi, ukulungisa ukubukeka okufunayo kanye nokuvumelana okuhle.
Abancanecel inika amandla amafomula e-viscous kanye nezihlanzi zejeli zibe usizo kakhulu futhi zithandeke kakhulu, ngobaAbancanecelizovumela abahlanzi bejeli bashiywe phezulu futhi basebenze isikhathi eside, ngakho-ke umphumela wokuhlanza ongcono.
- Ukujiya imiphumela
- Ukulungiswa kokuvumelana
- Ukuhambisana nama-ionic surfactants
- Izixazululo zokungafihli okuphezulu
