IHydroxypropyl methyl cellulose (HPMC) iyi-polymer engeyona i-ionic, i-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo. Umkhiqizo awunaphunga, awunambitheki, umpushana omhlophe ongenabuthi, ungancibilika emanzini abandayo ukuze wenze isisombululo se-viscous esisobala, ngokujiya, ukubopha, ukuhlakaza, ukuhlanganisa, ukwenza ifilimu, ukumisa okwesikhashana, ukukhangisa, i-gelling, umsebenzi ongaphezulu, izici ezifana njengokugcina umswakama kanye nama-colloid avikelayo.
I-HPMC esheshayo yeBanga isetshenziswa kakhulu kumakhemikhali endwangu, imikhiqizo yokuhlanza amakhemikhali yansuku zonke, izimonyo neminye imikhakha; njenge-shampoo, ukugeza umzimba, okokuhlanza ubuso, okokugcoba, ukhilimu, ijeli, i-toner, i-hair conditioner, imikhiqizo yesitayela, umuthi wokuxubha, amathe, amanzi ebhamuza lamathoyizi, njll.
Izici zomkhiqizo zebanga lansuku zonke lamakhemikhali i-hydroxypropyl methyl cellulose ikakhulukazi zifaka:
1. Izinto zokusetshenziswa zemvelo, ukucasuka okuncane, ukusebenza okuncane, ukuphepha nokuvikelwa kwemvelo;
2. Ukuncibilika kwamanzi nokujiya: kungancibilika emanzini abandayo ngokushesha, kuncibilike kwezinye izinyibilikisi zemvelo kanye nengxube yamanzi nezincibilikisi eziphilayo;
3. Ukuqina kanye nokwenyuka kwe-viscosity: ukukhuphuka okuncane kokuncibilika kuzokwakha isisombululo se-viscous esisobala, ukukhanya okuphezulu, ukusebenza okuzinzile, izinguquko ze-solubility nge-viscosity, i-viscosity ephansi, i-solubility enkulu; ngcono ngempumelelo ukuzinza kokugeleza kwesistimu;
4. Ukumelana nosawoti: I-HPMC iyi-polymer engeyona i-ionic, ezinzile kuzixazululo ezinamanzi zosawoti wensimbi noma ama-electrolyte aphilayo;
5. Umsebenzi ongaphezulu: isixazululo esinamanzi somkhiqizo sinomsebenzi ongaphezulu, futhi sinemisebenzi kanye nezakhiwo ze-emulsification, i-colloid evikelayo nokuzinza okuhlobene; ukungezwani kwendawo: 2% isixazululo samanzi ngu-42-56dyn / cm;
6. Ukuzinza kwe-PH: i-viscosity yesisombululo samanzi izinzile ngaphakathi kwebanga le-PH3.0-11.0;
7. Umphumela wokugcina amanzi: impahla ye-hydrophilic ye-HPMC ingangezwa emikhiqizweni ewudaka, unamathisele kanye ne-pasty ukuze kugcinwe umphumela wokugcina amanzi;
8. I-Thermal Gelation: Uma isisombululo se-aqueous sishiswa ekushiseni okuthile, siba yi-opaque size senze (i-poly) isimo se-flocculation, okwenza isixazululo silahlekelwe yi-viscosity. Kodwa ngemva kokupholisa, izophenduka ibe yisimo sokuqala sesixazululo futhi. Izinga lokushisa lapho kwenzeka khona i-gel kuncike ohlotsheni lomkhiqizo, ukugxila kwesisombululo kanye nezinga lokushisa;
9. Ezinye izici: izakhiwo ezinhle kakhulu zokwakha ifilimu, kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokubumbana, njll.
