Iqhaza elibalulekile le-HPMC odakeni oluxutshwe okumanzi ikakhulukazi linezici ezintathu ezilandelayo:
1. I-HPMC inomthamo omuhle kakhulu wokugcina amanzi.
2. Umthelela we-HPMC ekuvumelaneni kanye ne-thixotropy yodaka oluxutshwe okumanzi.
3. Ukusebenzisana phakathi kwe-HPMC nosimende.
Ukugcinwa kwamanzi wukusebenza okubalulekile kwe-HPMC, futhi kuwukusebenza abakhiqizi abaningi bakadaka lwemiksi emanzi abakunaka.
Umthelela wokugcina amanzi we-HPMC uncike esilinganisweni sokumuncwa kwamanzi sesendlalelo sesisekelo, ukwakheka kodaka, ukujiya koqweqwe lodaka, isidingo samanzi sodaka, kanye nesikhathi sokusetha sento yokusetha.
I-HPMC – ukugcinwa kwamanzi
Ukuphakama kwezinga lokushisa lejeli le-HPMC, kuba ngcono ukugcinwa kwamanzi.
Izici ezithinta ukugcinwa kwamanzi kodaka oluxubene olumanzi yi-HPMC viscosity, inani elingeziwe, ubuncane bezinhlayiyana kanye nezinga lokushisa lokusebenzisa.
I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-HPMC.Ngomkhiqizo ofanayo, imiphumela ye-viscosity elinganiswa ngezindlela ezihlukene iyahluka kakhulu, futhi eminye iphinda kabili umehluko.Ngakho-ke, uma kuqhathaniswa ama-viscosity, kufanele kwenziwe phakathi kwezindlela zokuhlola ezifanayo, okuhlanganisa izinga lokushisa, i-spindle, njll. Ngokuvamile, ukuphakama kwe-viscosity, kuba ngcono umphumela wokugcina amanzi.
Kodwa-ke, ukuphakama kwe-viscosity kanye nesisindo samangqamuzana esikhulu se-HPMC, ukwehla okuhambisanayo ekuncibilikeni kwayo kuzoba nomthelela omubi emandleni nasekusebenzeni kokwakhiwa kodaka.Ukuphakama kwe-viscosity, umphumela wokujiya wodaka, kodwa awulingani.Ukuphakama kwe-viscosity, i-viscous yodaka olumanzi, okubonisa ukunamathela ku-scraper ngesikhathi sokwakhiwa nokunamathela okuphezulu ku-substrate.Kodwa-ke, i-HPMC inomphumela omncane ekuthuthukiseni amandla esakhiwo sodaka olumanzi ngokwalo, okubonisa ukuthi ukusebenza kokulwa nokuhlehla akubonakali.Ngokuphambene, enye i-HPMC eguquliwe ene-viscosity emaphakathi nephansi ihle kakhulu ekuthuthukiseni amandla esakhiwo sodaka olumanzi.
Ukucoleka kwe-HPMC nakho kunomthelela othile ekugcinweni kwayo kwamanzi.Ngokuvamile, ku-HPMC ene-viscosity efanayo kodwa ukucoleka okuhlukile, uma i-HPMC icolisa, kuba ngcono umphumela wokugcina amanzi ngaphansi kwesamba esifanayo sokwengezwa.
