Ukusetshenziswa Okubanzi kweHydroxypropyl Methyl Cellulose
IHydroxypropyl methyl cellulose, ebizwa nge-(HPMC): i-hydroxypropyl methyl cellulose (HPMC) iyimpushana emhlophe engenaphunga, enganambitheki, engenabuthi, kunezinhlobo ezimbili zempushana esheshayo nengasheshi, esheshayo, Uma ihlangana namanzi abandayo, isheshe. ahlakazeke anyamalale emanzini. Ngalesi sikhathi, uketshezi alunayo i-viscosity. Ngemuva kwemizuzu emi-2, i-viscosity ye-liquid iyanda, yakha i-viscous colloid ebonakalayo. Uhlobo olungasheshi: Lungasetshenziswa kuphela emikhiqizweni yempushana eyomile njengempushana ephutshayo kanye nodaka lukasimende. Ngeke isetshenziswe ku-glue ewuketshezi nopende, futhi kuzoba ne-clumping.
A. Izakhiwo zomzimba namakhemikhali
1. Ukubukeka: Impushana emhlophe noma emhlophe, ayinaphunga futhi ayinambitheki.
2. Usayizi wezinhlayiya: izinga lokuphasa lika-100 mesh likhulu kuno-98.5%; izinga lokuphasa lika-80 mesh likhulu kuno-100%.
3. Izinga lokushisa le-Carbonization: 280-300°C.
4. Ukuminyana okubonakalayo: 0.25-0.70g/ (imvamisa cishe ku-0.5g/), amandla adonsela phansi athile 1.26-1.31.
5. Izinga lokushisa lokushintsha umbala: 190-200°C.
6. Ukushuba kobuso: Isixazululo samanzi esingu-20% singu-42-56dyn/cm.
7. Ukunyibilika: Kuncibilika emanzini nakwezinye izincibilikisi eziphilayo, njenge-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane, njll. ngesilinganiso esifanele. Isixazululo esinamanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu nokusebenza okuzinzile. Imikhiqizo enokucaciswa okuhlukile inamazinga okushisa e-gelation ahlukene, okuyi-thermal gelation property ye-HPMC. Ukunyibilika kuyahlukahluka nge-viscosity, i-viscosity ephansi, ukuncibilika okukhulu, ukucaciswa okuhlukile kwe-HPMC kunomehluko othile ekusebenzeni, futhi ukuhlakazeka kwe-HPMC emanzini akuthintwa inani le-pH.
8. Ngokuncipha kokuqukethwe kwe-methoxy, iphuzu lejeli le-HPMC liyakhula, ukuncibilika kwamanzi kuncipha, nomsebenzi ongaphezulu nawo uyancipha.
9. I-HPMC futhi inezici zekhono lokuqina, ukukhipha usawoti, okuqukethwe komlotha ophansi, ukuzinza kwe-pH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, impahla enhle kakhulu yokwenza ifilimu, ububanzi obubanzi bokumelana nama-enzyme, ukuhlakazeka nokubumbana.
Umsebenzi we-Hydroxypropyl methylcellulose:
• Ingakwazi ukujiyisa udaka olusanda kuxutshwa ukuze lube ne-viscosity ethile emanzi futhi ivimbele ukuhlukaniswa. (ukujiya)
• Ukugcinwa kwamanzi kuyisici esibaluleke kakhulu, esiza ukugcina inani lamanzi amahhala odakeni, ukuze izinto zikasimende zibe nesikhathi esengeziwe sokumanzisa ngemva kokufakwa kodaka. (ukugcinwa kwamanzi)
• Inempahla yokungenisa umoya, ekwazi ukwethula amabhamuza afanayo kanye namabhamuza amahle ukuze kuthuthukiswe ukusebenza kodaka.
