I-Hydroxypropyl methylcellulose (HPMC)iyinhlanganisela ehlukahlukene esetshenziswa kabanzi ezinhlobonhloboizimboningenxa yezakhiwo zayo eziningi.Isici esisodwa esibalulekile esithinta ukusebenza kwe-HPMC ubumsulwa bayo, obungaba nomthelela omkhulu ekubukekeni kwayo, ngenxa yalokho, nokusetshenziswa kwayo.Le ndatshana icubungula ukuhlobana phakathi kokuhlanzeka kwe-HPMC kanye ne-viscosity, ikhanyisela imithelela yayo emikhakheni eyahlukene.
I-HPMCkanye Nokubaluleka Kwaso:
I-HPMC, etholakala ku-cellulose yemvelo, ibhekana nokuguqulwa kwamakhemikhali ukuze yakhe i-polymer yokwenziwa enezici ezihlukile.Le nhlanganisela ithola ukusetshenziswa kwemithi, izimonyo, ukwakhiwa, nokunye, ngenxa yokuqina kwayo, ukumisa okwesikhashana, kanye nekhono lokwenza amafilimu.Kodwa-ke, ubumsulwa be-HPMC buvela njengento ebaluleke kakhulu ethonya lokhu kusebenza.
Umthelela Wobumsulwa ku-Viscosity:
Ukuhlanzeka kudlala indima ebalulekile ekunqumeni i-viscosity yezixazululo ze-HPMC.Amazinga aphezulu wokuhlanzeka ngokuvamile aholela emiphumeleni ye-viscosity engaguquki futhi ebikezelwe.Ukungcola, okufana nensalelai-cellulose, ingathula ukuhluka kwe-viscosity, okuthinta ukusebenza okuphelele kwemikhiqizo esekelwe ku-HPMC.
Izakhiwo zokujiya kanye nokugawula:
Ezicelweni ezidinga ukujiya kanye ne-gelling, njengemikhiqizo yokudla kanye nokwakheka kwemithi,I-HPMCubumsulwa buthinta ngqo ukuthungwa nokuzinza okufunayo.Ubumsulwa obuphakeme I-HPMC iqinisekisa ukulawula okunembile phezu kwe-viscosity, ikhiqiza imikhiqizo ephezulu enekhwalithi engaguquki.
Izici zokumiswa:
Ikhono le-HPMC lokumisa izinhlayiya ekwenziweni koketshezi lithintwa ubumsulwa bayo.Ukungcola kungavimbela ukwakheka kokumiswa okuzinzile, okungaba nomthelela ekusebenzeni kwemithi yoketshezi lomlomo nokunye ukumiswa.
Ukwakhiwa Kwefilimu kanyeUkugqoka:
Ukuhlanzeka kuthonya izici zokwenza ifilimu ye-HPMC, ebalulekile ezinhlelweni ezifana nokugcotshwa kwamaphilisi emithi.I-HPMC ehlanzekile ngokungaguquki iqinisekisa ukunamathela okufanayo nokuthembekile, okuthinta amaphrofayili okukhishwa kwezidakamizwa nokuzinza kweshalofu.
Imboni yezokwakha:
Emkhakheni wezokwakha, lapho i-HPMC isetshenziswa njengesengezo sikasimende, ukuhlanzeka kuthinta ngqo umthamo wayo wokugcina amanzi, ukusebenza, kanye nezakhiwo zokunamathela.I-HPMC enobumsulwa obuphezulu inikela ekushintshaneni okufiswayo nasekusebenzeni kwezinto zokwakha.
Ukuhlanzeka kwe-HPMC kuyipharamitha ebalulekile ethinta kakhulu i-viscosity yayo, ngenxa yalokho, ukusebenza kwayo kuzo zonke izimboni ezihlukahlukene.Amazinga aphezulu okuhlanzeka aholela emiphumeleni ethembeke kakhudlwana nengaguquguquki ekushubeni, ekumisweni, nasekufakeni amafilimu.Abakhiqizi nabacwaningi ngokufanayo kufanele babeke phambili ikhwalithi nobumsulwa be-HPMC ukuze kuqinisekiswe ukusebenza kahle nokuthuthukisa ukusebenza kahle kwemikhiqizo emikhakheni eyahlukene.Njengoba lesi sihloko sigqamisa, ukuqonda umthelela wokuhlanzeka kwe-HPMC ku-viscosity kuyisihluthulelo sokuvula amandla ayo aphelele ezinhlelweni eziningi.
