3.2 Ii-aggregates kunye nezihluzi:
I-HPMC ikwanxibelelana nee-aggregates kunye nezihluzi, ezichaphazela iipropathi zoomatshini bodaka.Olu phononongo luvavanya umphumo we-HPMC ekusasazweni kwezi nxalenye kunye negalelo layo kumandla odaka.
Impembelelo ekusebenzeni kodaka:
4.1 Ukunamathela kunye nomanyano:
Ukubambelela kunye nokudityaniswa kobumbano kunye nodaka lodaka lubalulekile kulwakhiwo oluhlala ixesha elide noluthembekileyo.Eli candelo livavanya impembelelo ye-HPMC kwezi zakhiwo kwaye lixoxa ngeendlela ezinegalelo ekuphuculeni ukubambelela.
4.2 Ukwakhiwa:
Ukusetyenzwa yinto ephambili kwisicelo sodaka.Umphumo we-HPMC ekusebenzeni kodaka luphononongwa, kubandakanywa nefuthe layo ekululameni kwesicelo kunye nokugqiba.
4.3 Amandla oomatshini:
Indima ye-HPMC ekuphuculeni amandla omatshini wodaka yaphandwa kuthathelwa ingqalelo impembelelo yayo kuxinzelelo, ukunyanzeliswa kunye namandla okuguquguquka.Uphononongo lukwaxoxa ngedosi efanelekileyo ye-HPMC ukufezekisa ubunzulu obufunwayo.
Ukuqina kunye noKuxhathisa:
5.1 Ukuqina:
Ukomelela kodaka kubalulekile ukumelana nemiba yokusingqongileyo kunye nokugcina imfezeko yesakhiwo kwixesha elide.Eli candelo livavanya indlela i-HPMC enokuphucula ngayo ukuqina kwebhondi kunye nodaka lokutyabeka.
5.2 Ukuchasana nezinto zangaphandle:
HPMC kuxoxwe ngayo ukuphucula isakhono sodaka ukuxhathisa izinto ezifana nokungena kwamanzi, ukuba sesichengeni imichiza, kunye notshintsho lobushushu.Olu phononongo luphonononga iindlela apho i-HPMC i-arhente ekhuselekileyo yokukhusela.
ISikhokelo sokuSebenzisa kunye noKuqulunqa:
6.1 Ukuphunyezwa okusebenzayo:
Usetyenziso olusebenzayo lwe-HPMC ekudibaneni kunye nodaka lokutyabeka luyaphononongwa, luqaqambisa izifundo eziyimpumelelo kunye nokubonisa ukuba nokwenzeka kokubandakanya i-HPMC kwiiprojekthi zokwakha.
6.2 Uphuhliso lwezikhokelo:
Izikhokelo zokuqulunqa ii-mortars kunye ne-HPMC zinikezelwe, kuthathelwa ingqalelo izinto ezifana nedosi, ukuhambelana nezinye izongezo, kunye neenkqubo zokuvelisa.Iingcebiso ezisebenzayo zokufumana iziphumo ezizezona zilungileyo ziyaxoxwa.
Imingeni kunye nezinto ezilindelekileyo kwixesha elizayo:
