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 akuchatshazelwa yi-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 ekhawulezayo i-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 nemveliso yokunamathisela.
2. Amanzi abandayo ngokukhawuleza 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 samanzi sifudumala kwiqondo lokushisa elithile, liya kuba li-opaque kuze kube yilapho i-flocculation state yenziwe, 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.
