Baaritaanka Viscosity-ga Cellulose Ether

Dheef-dhalaalkaether-yada cellulose, sida Hydroxypropyl Methylcellulose (HPMC) ama Carboxymethyl Cellulose (CMC), waa halbeeg muhiim ah oo saameyn kara waxqabadkooda codsiyada kala duwan. Viscosity waa cabbir lagu cabbiro iska caabbinta dareeraha ee socodka, waxaana saameyn kara arrimo ay ka mid yihiin xoojinta, heerkulka, iyo heerka beddelka ether-ka cellulose.

Waa kan hage guud oo ku saabsan sida loo sameyn karo baaritaannada viscosity ee ether-yada cellulose:

Habka Cabirka Brookfield:

Viscometer-ka Brookfield waa qalab caadi ah oo loo isticmaalo cabbiraadda daxalka dareeraha. Tallaabooyinka soo socda waxay bixiyaan dulmar aasaasi ah oo lagu sameeyo tijaabada daxalka:

1. Diyaarinta Muunad:
   • Diyaari isku-darka la yaqaan ee xalka ether-ka cellulose. Isu-geynta la doortay waxay ku xirnaan doontaa shuruudaha gaarka ah ee codsiga.
2. Is-waafajinta Heerkulka:
   • Hubi in muunaddu ay la mid tahay heerkulka tijaabada ee la rabo. Viscosity-gu wuxuu ku xirnaan karaa heerkulka, sidaa darteed tijaabinta heerkul la xakameeyey ayaa muhiim u ah cabbiraadda saxda ah.
3. Habaynta:
   • Hagaaji cabbirka viskometer-ka Brookfield adoo isticmaalaya dareerayaal cabbir caadi ah si loo hubiyo akhrinta saxda ah.
4. Soo rarista Muunadda:
   • Ku shub qadar ku filan oo ah xalka ether-ka cellulose qolka viscomer-ka.
5. Xulashada Spindle:
   • Dooro isdul-xidh ku habboon iyadoo lagu saleynayo heerka la filayo ee viscosity-ga muunadda. Isdul-xidhyo kala duwan ayaa loo heli karaa heerarka viscosity-ga hooseeya, dhexdhexaadka ah, iyo kuwa sare.
6. Cabbirka:
   • Ku dhex geli dunka muunadda, oo bilow qalabka cabbira. Dunku wuxuu ku wareegayaa xawaare joogto ah, iska caabbinta wareeggana waa la cabbiraa.
7. Xogta Diiwaangelinta:
   • Ka duub akhrinta viscosity-ga shaashadda viscometer-ka. Cutubka cabbirku wuxuu caadi ahaan ku jiraa sentipoise (cP) ama millipascal-seconds (mPa·s).
8. Cabbiraadaha Ku Celi:
   • Samee cabbiro badan si loo hubiyo in dib loo soo saari karo. Haddii uu dheellitirku isbeddelo waqtiga ka dib, cabbiro dheeraad ah ayaa laga yaabaa in loo baahdo.
9. Falanqaynta Xogta:
   • Falanqee xogta viscosity-ga iyadoo la eegayo shuruudaha codsiga. Codsiyada kala duwan waxay yeelan karaan bartilmaameedyo viscosity gaar ah.

Arrimaha Saameeya Iftiinka:

1. Xoojinta:
   • Xoogaa badan oo ah xalalka ether-ka ee cellulose-ka ayaa badanaa keena viscosities sare.
2. Heerkulka:
   • Viscosity-gu wuxuu noqon karaa mid u nugul heerkulka. Heerkulka sare wuxuu yareyn karaa viscosity-ga.
3. Heerka Beddelka:
   • Heerka beddelka ether-ka cellulose wuxuu saameyn karaa dhumucdiisa iyo, sidaas darteed, dheellitirkiisa.
4. Heerka Xidhitaanka:
   • Viscosity-gu wuu kala duwanaan karaa iyadoo la eegayo heerka gooynta, viscomers-yada kala duwanna waxay ku shaqayn karaan heerarka gooynta kala duwan.

Had iyo jeer raac tilmaamaha gaarka ah ee uu bixiyo soo saaraha ether-ka cellulose si loo baaro viscosity-ga, maadaama habraacyadu ay ku kala duwanaan karaan nooca ether-ka cellulose iyo codsigeeda loogu talagalay.
