I-Hydroxypropyl methyl cellulose (HPMC) i-polymer engeyiyo i-ionic, i-ether ye-cellulose engekho i-ionic eyenziwe kwi-cellulose ye-polymer yendalo. Imveliso ayinavumba, ayinancasa, ayinayo ityhefu emhlophe engumgubo, inokunyibilika emanzini abandayo ukwenza isisombululo se-viscous esicacileyo, kunye nokuqina, ukubopha, ukusabalalisa, ukumisa, ukwenza ifilimu, ukuxhoma, i-adsorbing, i-gelling, umsebenzi ophezulu, iimpawu ezinjalo. njengokugcina ukufuma kunye ne-colloids ekhuselayo.
I-HPMC yeBanga ngoko nangoko isetyenziswa ikakhulu kwiikhemikhali ezilukiweyo, kwiimveliso zemihla ngemihla zokucoca iikhemikhali, izithambiso nezinye iinkalo; ezifana neshampu, ukuhlamba umzimba, isicoci sobuso, i-lotion, i-cream, ijeli, i-toner, isilungisi seenwele, iimveliso zesitayile, intlama yamazinyo, amathe, amanzi eqamza lokudlala, njl.
Iimpawu zemveliso yomgangatho wemichiza yemihla ngemihla ye-hydroxypropyl methyl cellulose ikakhulu ibandakanya:
1. Izinto eziluhlaza zendalo, ukucaphuka okuphantsi, ukusebenza kancinci, ukhuseleko kunye nokukhuselwa kwendalo;
2. Ukunyibilika kwamanzi kunye nokuqina: inokunyibilika emanzini abandayo ngokukhawuleza, i-soluble kwezinye i-solvents eziphilayo kunye nomxube wamanzi kunye ne-organic solvents;
3. Ukuqina kunye nokunyuka kwe-viscosity: ukunyuka okuncinci kokuchithwa kuya kwenza isisombululo esicacileyo se-viscous, ukukhanya okuphezulu, ukusebenza okuzinzileyo, utshintsho lwe-solubility kunye ne-viscosity, i-viscosity ephantsi, i-solubility enkulu; ukuphucula ngokufanelekileyo ukuzinza kokuhamba kwenkqubo;
4. Ukumelana netyuwa: I-HPMC i-polymer engeyiyo i-ionic, izinzile kwizisombululo ezinamanzi zetyuwa zetsimbi okanye i-electrolytes ye-organic;
5. Umsebenzi womphezulu: isisombululo se-aqueous semveliso sinomsebenzi ongaphezulu, kwaye sinemisebenzi kunye neempawu ze-emulsification, i-colloid yokukhusela kunye nokuzinza kwesihlobo; ukunyanzeliswa komhlaba: 2% isisombululo samanzi ngu-42-56dyn / cm;
6. Ukuzinza kwe-PH: i-viscosity yesisombululo samanzi izinzile ngaphakathi koluhlu lwe-PH3.0-11.0;
7. Isiphumo sokugcina amanzi: ipropathi ye-hydrophilic ye-HPMC inokongezwa kwi-slurry, intlama kunye neemveliso ze-pasty ukugcina umphumo ophezulu wokugcina amanzi;
8. I-Thermal Gelation: Xa isisombululo esinamanzi sifudunyezwa kwiqondo elithile lobushushu, liba li-opaque de lifake (i-poly) i-flocculation state, eyenza isisombululo silahlekelwe yi-viscosity yayo. Kodwa emva kokupholisa, iya kujika ibe yimeko yesisombululo sokuqala kwakhona. Iqondo lokushisa apho kwenzeka khona i-gel phenomenon kuxhomekeke kuhlobo lwemveliso, ukuxinwa kwesisombululo kunye nesantya sokufudumala;
9. Ezinye iimpawu: iipropathi ezigqwesileyo zokwenza ifilimu, kunye noluhlu olubanzi lokumelana ne-enzyme, ukusabalalisa kunye nokubambisana, njl.
