Baaritaanka Viscosity Cellulose Ether

viscosity eeethers cellulose, sida Hydroxypropyl Methylcellulose (HPMC) ama Carboxymethyl Cellulose (CMC), waa halbeeg muhiim ah oo saameyn ku yeelan kara waxqabadkooda codsiyada kala duwan. Viscosity waa cabbirka caabbinta dareeraha qulqulka, waxaana saameyn ku yeelan kara arrimo ay ka mid yihiin xoojinta, heerkulka, iyo heerka beddelka etherka cellulose.

Halkan waxaa ah hage guud oo ku saabsan sida baaritaanka viscosity ee ethers cellulose loo samayn karo:

Habka Viscometer ee Brookfield:

Viscometer-ka Brookfield waa qalab caadi ah oo loo isticmaalo in lagu cabbiro viscosity-ka dareeraha. Talaabooyinka soo socdaa waxay bixinayaan tilmaamo aasaasi ah oo lagu samaynayo tijaabada viscosity:

1. Tusaalaha Diyaarinta:
   • Diyaari fiirsashada la og yahay ee xalka etherka cellulose. Xoojinta la doortay waxay ku xirnaan doontaa shuruudaha gaarka ah ee codsiga.
2. Isku dheelitirka heerkulka:
   • Hubi in muunadku la mid yahay heerkulka la rabo. Viscosity wuxuu noqon karaa mid ku-tiirsanaan heer kul ah, markaa tijaabinta heerkulka la xakameeyey ayaa muhiim u ah cabbirada saxda ah.
3. Qalabaynta:
   • Cabbir viskometer-ka Brookfield adoo isticmaalaya dareerayaasha cabbiraadda caadiga ah si loo xaqiijiyo akhrinta saxda ah.
4. Soodejinaya Tusaalaha:
   • Ku shub qadar ku filan oo ah dareeraha etherka cellulose qolka viscometerka.
5. Xulashada Spindle-ka:
   • Dooro dunta saxda ah oo ku salaysan kala duwanaanshaha viscosity ee la filayo ee muunadda. Sariiro kala duwan ayaa loo heli karaa kala duwanaanshaha hoose, dhexe, iyo sare ee viscosity.
6. Cabbirka:
   • Dhex geli dunta dunta muunada, oo billow fiisaha. Spindle-ku wuxuu ku wareegaa xawaare joogto ah, waxaana la cabbiraa caabbinta wareegga.
7. Xogta Duubista:
   • Ka duub akhriska viscosity tusaha muuqalka Halbeegga cabbiraadda ayaa caadi ahaan ah centipoise (cP) ama millipascal-ilbiriqsi (mPa·s).
8. Ku celceli Cabbiraadaha:
   • Samee cabbirro badan si aad u hubiso soo saarista. Haddii viscosity-ku kala duwan yahay waqtiga, cabbiraadyo dheeraad ah ayaa laga yaabaa inay lagama maarmaan noqoto.
9. Falanqaynta Xogta:
   • Falanqee xogta viscosity ee macnaha guud ee shuruudaha codsiga. Codsiyada kala duwan ayaa laga yaabaa inay leeyihiin bartilmaameedyo viscosity gaar ah.

Waxyaalaha Saameeya Viscosity:

1. Xoog-saarista:
   • Heerarka sare ee xalalka ether cellulose waxay badanaa keenaan viscosities sare.
2. Heerkulka:
   • Viscosity wuxuu noqon karaa heer-kulul. Heerkulka sare wuxuu yarayn karaa viscosity.
3. Heerka Beddelka:
   • Heerka beddelka ether-ka cellulose wuxuu saameyn karaa dhumucdiisa iyo, sidaas awgeed, viscositykeeda.
4. Qiimaha Jeex:
   • Viscosity wuxuu ku kala duwanaan karaa heerka dhogorta, iyo viscometers kala duwan ayaa laga yaabaa inay ku shaqeeyaan heerar kala duwan.

Had iyo jeer raac tilmaamaha gaarka ah ee ay bixiso soo saaraha etherka cellulose si aad u tijaabiso viscosity, maadaama habraacyadu ay kala duwanaan karaan iyadoo ku saleysan nooca etherka cellulose iyo codsigeeda loogu talagalay.
