Hydroxypropyl Methylcellulose (HPMC) Teko ea Teko ea Viscosity

Ho etsa liteko tsa viscosity bakeng sa Hydroxypropyl Methylcellulose (HPMC) ho kenyelletsa ho lekanya viscosity ea tharollo ea HPMC maemong a fapaneng le mocheso. Mona ke mokhoa o akaretsang oa ho etsa liteko tsa viscosity:

Lintho Tse Hlokehang:

  1. Hydroxypropyl Methylcellulose (HPMC) phofo
  2. Metsi a silafetseng kapa solvent (e loketseng kopo ea hau)
  3. Sesebelisoa sa ho lekanya viscosity (mohlala, viscometer)
  4. Molamu o hlohlelletsang kapa moferefere wa makenete
  5. Libeake kapa lijana tsa ho kopanya
  6. Thermometer
  7. Sebapa-nako kapa stopwatch

Mokhoa:

  1. Tokisetso ea Tharollo ea HPMC:
    • Lokisetsa letoto la litharollo tsa HPMC tse nang le likhakanyo tse fapaneng (mohlala, 1%, 2%, 3%, joalo-joalo) metsing a hloekisitsoeng kapa motsoako oa khetho ea hau. Etsa bonnete ba hore phofo ea HPMC e hasane ka ho feletseng ka mokelikeli ho thibela ho bokellana.
    • Sebelisa cylinder e fumaneng mangolo kapa ho leka-lekanya ho lekanya palo e loketseng ea phofo ea HPMC 'me u e kenye mokelikeli ha u ntse u susumetsa ka ho tsoelang pele.
  2. Ho kopanya le ho qhibiliha:
    • Hlohlelletsa tharollo ea HPMC hantle ka ho sebelisa molamu o susumetsang kapa magnetic stirrer ho etsa bonnete ba ho qhibiliha ka ho feletseng ha phofo. Lumella tharollo ho hydrate le ho teteaneng metsotso e seng mekae pele u hlahloba viscosity.
  3. Ho lekanya Viscometer:
    • Haeba u sebelisa viscometer, etsa bonnete ba hore e hlophisitsoe hantle ho latela litaelo tsa moetsi. Beha sesebelisoa ho li-setting tse nepahetseng bakeng sa tekanyo ea viscosity.
  4. Tekanyo ea Viscosity:
    • Tšela tekanyo e nyane ea tharollo ea HPMC e lokiselitsoeng ka phaposing ea ho lekanya ea viscometer.
    • Kenya seluloana kapa ntho e potolohang ea viscometer ka har'a tharollo, ho etsa bonnete ba hore e qoelisoa ka botlalo 'me e se ke ea ama tlase kapa mahlakoreng a kamore.
    • Qala viscometer 'me u tlalehe ho bala ha viscosity ho bontšitsoe seletsa.
    • Pheta tekanyo ea viscosity bakeng sa khatello e 'ngoe le e' ngoe ea tharollo ea HPMC, ho netefatsa hore mocheso le maemo a mang a liteko a lula a tsitsitse.
  5. Phetoho ea Mocheso:
    • Haeba u lekola phello ea mocheso ho viscosity, lokisa litharollo tse ling tsa HPMC maemong a batloang le maemo a mocheso.
    • Sebelisa thermometer ho lekola mocheso oa tharollo le ho fetola ha ho hlokahala ka ho hlapa metsi kapa tikoloho e laoloang ke mocheso.
  6. Tlhahlobo ea Lintlha:
    • Rekota 'malo oa viscosity bakeng sa mahloriso a mang le a mang a HPMC le mocheso o lekiloeng.
    • Sekaseka datha ho tseba mekhoa kapa likamano lipakeng tsa mahloriso a HPMC, mocheso le viscosity. Rala liphetho ho kerafo haeba u lakatsa ho bona kamano ka mahlo a kelello.
  7. Tlhaloso:
    • Hlalosa lintlha tsa viscosity ho latela litlhoko tsa hau tse ikhethileng tsa kopo le lintlha tsa moralo. Nahana ka lintlha tse kang litšobotsi tse lakatsehang tsa phallo, thepa ea ho sebetsana le maemo a ho sebetsa.
  8. Litokomane:
    • Ngola mokhoa oa liteko, ho kenyeletsoa lintlha tsa tharollo ea HPMC e lokisitsoeng, litekanyo tsa viscosity tse nkuoeng, le maikutlo afe kapa afe a fumanoeng tekong.

Ka ho latela mokhoa ona, o ka etsa tlhahlobo ea viscosity test bakeng sa Hydroxypropyl Methylcellulose (HPMC) mme oa fumana lintlha tsa bohlokoa mabapi le thepa ea eona ea rheological le boitšoaro tlas'a maemo a fapaneng le maemo a mocheso. Fetola mokhoa o hlokahalang ho latela litlhoko tse khethehileng tsa tlhahlobo le ho fumaneha ha lisebelisoa.
