Cellulose Ethen (MHEC)

Methyl hydroxeyyl celluloulose. Mona ke kakaretso ea mhec:

Sebopeho:

MHC ke selefounu e fetotsoeng Ether e sentsoeng ho tsoa ka seleng ka makhetlo a mangata. E tšoauoa ka ho ba teng ha lihlopha ka bobeli le tsa hydroxethyl ho sehlopha sa mokokotlo oa sele cellulose.

LITLHAKISO:

1. Qeto ea metsi: MHEC e qhibiliha ka metsing a batang, a etsa tharollo e hlakileng le e hlahlojoang.
2. Thickening: E ​​fana ka thepa e ntle e metle ea ho etsa hore e bohlokoa e le ea bohlokoa joalo ka mofosi oa Rheology ka mekhoa e fapaneng.
3. Sebopeho sa lifilimi: MHER e ka theha lifilimi tse fetohang le tse kopaneng, li kenya letsoho tšebelisong ea eona ho bolaoa le made.
4. Ho bolokoa: Ho fana ka botsitso ho bomumu le ho thibela libaka, ho ntlafatsa bophelo ba lihlahisoa tsa lihlahisoa tse entsoeng.
5. Khomo: MHEC e tsejoa ka thepa ea eona e khomaretsoeng, e kenya letsoho ho ntlafatsang lits'ebetsong tse itseng.

Likopo:

1. Indasteri ea kaho:
   • Lits'ebetso tsa Tile: MHEC e sebelisoa meralo ea Tile ho ntlafatsa ho ikoetlisa, ho boloka metsi le ho tšoarella.
   • Le ho ipheta ebe o sebetsa ka lefu la samente e thehiloeng ho saense ebe e fana ka matla a metsi le ho ntlafatsa.
   • Likhatiso tsa ho iphahamisa: MHEC e sebelisoa likotong tsa boithati bakeng sa thepa ea eona e tolang le ho fetola thepa.
2. Likotsi le lipente:
   • MHC e sebelisoa lipelong tse thehiloeng metsing le makhapetla a leoatle a joaloka thipa le semola. E thusa ho ba le bo-shutelity le ts'ebetso e akaretsang ea koluoa.
3. LITLHAKU:
   • MHEC e sebelisoa ka marena a fapaneng ho ntlafatsa ho latela melao le ho ntlafatsa thepa ea Rheopenion ea mekhoa ea khomarela.
4. Merima:
   • Li-Pharmaceutical, MHC e sebelisoa e le mothetsi, ho senyeha, le moemeli ea etsang filimi ho liforomo tsa tablet.

Ts'ebetso ea Tlhahiso:

Ho hlahisoa ha MHEC ho kenyelletsa sellout sa cellulose se nang le motsoako oa methyl chloride le ergylene oxide. Maemo a ikhethang le mefuta e meng ea khale e laoloa ho fihlela tekanyo e lakatsehang ea sebaka (DS) le ho etsa thepa ea sehlahisoa sa ho qetela.

Taolo ea Boleng:

Mehato ea taolo ea boleng, ho kenyelletsa mekhoa ea ho hlahloba e kang ea nyutlelie (nmr) Spectroscopy

Ho feto-fetoha ha maemo ho etsa hore ho be motsoako oa bohlokoa ka mefuta e mengata ea liforomo, ho kenya letsoho ho ntlafatsang lisebelisoa tsa kaho, lits'ila, likhakanyo le meriana. Baetsi ba thepa ba ka fana ka limaraka tse fapaneng ho fihlela litlhoko tse fapaneng tsa indasteri e fapaneng.
