Izinzuzo kanye Nezinhlobo ze-HPMC

IHydroxypropylmethylcellulose (HPMC) iyinhlanganisela esetshenziswa kabanzi enezinhlobonhlobo zezicelo zezimboni, ezentengiselwano, nezokunakekelwa kwezempilo.I-HPMC iyinhlanganisela engenaphunga, ayinambitheki, futhi engenabuthi etholakala ku-cellulose.Kuyinhlanganisela encibilikayo emanzini esetshenziswa ezinhlobonhlobo zokudla, izimonyo, izidakamizwa, kanye nemithi.I-HPMC yaziwa ngekhono layo elihle kakhulu lokwenza ifilimu, izakhiwo zokunamathela namandla okugcina amanzi.Yaziwa nangokuthi i-viscosity yayo enhle kakhulu, ukuzinza nokuhambisana nezinhlobonhlobo zezinto.

Izinhlobo ze-HPMC:

Kunezinhlobo ezimbalwa ze-HPMC emakethe, ngayinye enezakhiwo ezihlukile zomzimba namakhemikhali.Nazi ezinye izinhlobo ezijwayelekile ze-HPMC:

1. I-HPMC ye-viscosity ephansi:

I-viscosity ephansi ye-HPMC ibonakala ngesisindo esiphansi samangqamuzana kanye nezinga eliphansi lokushintshwa.Ngenxa yezakhiwo zayo ezinhle kakhulu zokubopha, ivame ukusetshenziswa njenge-binder kanye ne-disintegrant kumaphilisi.

2. I-HPMC ye-viscosity emaphakathi:

I-viscosity emaphakathi I-HPMC inesisindo samangqamuzana amaphakathi kanye nezinga lokushintshwa.Ivame ukusetshenziselwa ukuzinzisa ama-emulsions, ukumiswa kanye namagwebu embonini yokudla neziphuzo.

3. High viscosity HPMC:

I-viscosity ephezulu ye-HPMC ibonakala ngesisindo samangqamuzana aphezulu kanye nezinga eliphezulu lokushintshwa.Isetshenziswa kakhulu njenge-thickener ne-ejenti ye-gelling ezimbonini zokudla nezimonyo.

4. Ukwelashwa okungaphezulu kwe-HPMC:

I-HPMC ephathwayo ebusweni iphathwa ngamakhemikhali ahlukahlukene ukuze kulungiswe izindawo zayo ezingaphezulu.Ngokuvamile isetshenziswa njengesengezo embonini yokwakha ukuthuthukisa izakhiwo zezinto ezisekelwe usimende.

Izinzuzo ze-HPMC:

I-HPMC iletha izinzuzo eziningi ezimbonini ezihlukahlukene.Nazi ezinye izinzuzo ezingaba khona ze-HPMC:

1. Iphephile futhi ayinabo ubuthi:

Enye yezinzuzo eziyinhloko ze-HPMC ukuphepha kwayo nokungabi nobuthi.I-HPMC isuselwa ku-cellulose, inhlanganisela yemvelo.Ayicasuli futhi isikhumba, amehlo kanye nolwelwesi lwamafinyila, okwenza ibe isithako esiphephile emikhiqizweni eyahlukene.

2. Ukuncibilika kwamanzi:

I-HPMC incibilika kakhulu emanzini, okuyenza ibe isithako esihle kakhulu semikhiqizo ehlukahlukene edinga ukugcinwa kwamanzi nokunamathela.Ivamise ukusetshenziswa njenge-binder kanye ne-disintegrant embonini yokudla neyokwenza imithi.

3. Ikhono lokwenza ifilimu:

I-HPMC inamakhono amahle kakhulu okwenza ifilimu, okuyenza ibe isithako esihle kakhulu semikhiqizo ehlukahlukene edinga ukumbozwa okuyisivikelo.Isetshenziswa kakhulu embonini yezemithi yokugqoka amaphilisi namaphilisi.

4. Viscosity kanye nokujiya izakhiwo:

I-HPMC ine-viscosity enhle kakhulu kanye nezindawo zokujiya, okuyenza ibe isithako esihle kakhulu semikhiqizo ehlukahlukene edinga ukuthungwa okuminyene, okubushelelezi.Isetshenziswa kakhulu ezimbonini zokudla nezimonyo ukujiyisa amasoso namaloshini.

5. Ukuzinza nokuhambisana:

I-HPMC inokusimama okuhle kakhulu nokuhambisana nezinto ezihlukahlukene, okuyenza ibe isithako esihle kakhulu emikhiqizweni ehlukahlukene edinga ukuzinza nokuhambisana.Ivamise ukusetshenziswa embonini yezemithi ukuze kuzinziswe ukwakheka kwemithi.

I-HPMC iyinhlanganisela esebenza ngezinto eziningi eletha izinzuzo eziningi ezimbonini ezihlukahlukene ezihlanganisa ukudla, izimonyo kanye nemithi.Izakhiwo zayo eziyingqayizivele zomzimba namakhemikhali ziyenza ibe isithako esihle kakhulu emikhiqizweni ehlukahlukene, okuhlanganisa ama-binders, ama-disintegrants, ama-emulsions, ama-suspending agents, amagwebu, ama-thickeners, ama-gelling agents, kanye nabaqambi bamafilimu.I-HPMC futhi iphephile futhi ayinabo ubuthi, okuyenza ibe isithako esihle kakhulu emikhiqizweni ehlukahlukene edinga ukuphepha kanye nokungabi nobuthi.Izinhlobo ezahlukahlukene ze-HPMC ezitholakala emakethe zinikeza izimboni ezahlukahlukene ngezinketho ezahlukahlukene ongakhetha kuzo ngokwezidingo nezidingo zazo ezithile.
