I-HPMC inokunyibilika kwi-solvent exutywe namanzi abandayo kunye ne-organic matter ukwenza isisombululo se-viscous ebonakalayo.Isisombululo samanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu kunye nokuzinza okunamandla.Ukutshatyalaliswa kwayo emanzini akuchaphazeli i-pH.Ineziphumo ezityebileyo kunye nezokunqanda ukukhenkceza kwishampu kunye nejeli yeshawa, kwaye inokugcinwa kwamanzi kunye neempawu ezintle zokwenza ifilimu yeenwele kunye nolusu.Ngokunyuka okukhulu kwezixhobo ezisisiseko, i-cellulose (i-antifreeze thickener) inokunciphisa kakhulu iindleko kwaye ifumane iziphumo ezifanelekileyo xa isetyenziswa kwishampu kunye nejeli yeshawa.
Ibakala lemihla ngemihla lemichiza yamanzi abandayo ye-hydroxypropyl methyl cellulose inezi mpawu zilandelayo zemveliso:
1. Ukusebenza kakuhle kokugcinwa kwamanzi.I-HPMC ineempawu ze-hydrophilic.Inokugcina ukugcinwa kwamanzi aphezulu kwi-paste, i-paste kunye neemveliso zokunamathisela.
2. Amanzi abandayo esheshayo i-hydroxypropyl methylcellulose HPMC isebenzisa izinto eziluhlaza zendalo, ezinomsebenzi omnene, ukucaphuka okuphantsi, ukukhuselwa kwendalo kunye nokhuseleko.
3. I-PH izinzile, kwaye i-viscosity yesisombululo samanzi ngokuqhelekileyo izinzile kuluhlu lwe-pH3.0 ukuya kwi-11.0.
4. Isisombululo samanzi semveliso sinomsebenzi ongaphezulu, i-emulsification, ukukhuselwa kwe-colloid kunye nokuzinza kwesihlobo.Ukunyanzeliswa kwayo komhlaba malunga ne-2% kunye nesisombululo samanzi ngu-42-56dyn / cm.
5. Ukuqina kunye ne-solubility yamanzi, inokuchithwa ngokukhawuleza emanzini abandayo, ezinye i-solvents eziphilayo kunye nemixube ene-solvents eziphilayo.
6. Ukwandisa i-viscosity: xa inani elincinci lokuchithwa linyuka, isisombululo se-viscous esicacileyo siya kwenziwa, esineempawu zokusebenza okuzinzile kunye nokucaca okuphezulu.I-solubility iya kutshintsha kunye ne-viscosity.I-viscosity ephantsi, inqanaba elikhulu lokuchithwa, elinokuphucula ngokufanelekileyo ukuzinza kokuhamba kwenkqubo.
7. Ukuxhathisa ityuwa ngokugqwesileyo.I-HPMC yi-polymer engeyiyo i-ionic, ezinzileyo kwi-organic electrolyte isisombululo esinamanzi okanye i-electrolyte ephilayo.
8. I-Thermal Gelation: xa isisombululo esinamanzi sifudumala kwiqondo lokushisa elithile, liya kuba li-opaque de liveliswe i-flocculation state, eya kwenza ngokupheleleyo isisombululo silahlekelwe yi-viscosity yayo.Nangona kunjalo, iya kutshintsha ibe yimeko yesisombululo sokuqala emva kokupholisa.Ngengxaki ye-gel ye-thermal, iqondo lokushisa lixhomekeke ikakhulu kuhlobo lwemveliso, ukugxininiswa kwesisombululo kunye nesantya sokufudumala.
9. I-HPMC inezinye iipropati kwintsimi yezicelo zeekhemikhali zemihla ngemihla, ezifana neempawu ezibalaseleyo zokwenza ifilimu, ukuxhathisa i-enzyme ebanzi, ukusabalalisa kunye neempawu zokudibanisa.
