Tijaabinta viscosity ee heerka cuntada sodium karboxymethyl cellulose (CMC) ayaa muhiim u ah hubinta shaqeynteeda iyo waxqabadkeeda codsiyada kala duwan ee cuntada. Cabbirrada viscosity-ka ayaa ka caawiya soo-saareyaasha inay go'aamiyaan dhumucda iyo xasilinta awoodaha xalalka CMC, kuwaas oo lama huraan u ah gaaritaanka sifooyinka badeecada la doonayo sida texture, dareenka afka, iyo xasilloonida. Halkan waxaa ah hage dhammaystiran oo ku saabsan habka tijaabada ee heerka cunnada ee sodium CMC viscosity:

1. Mabda'a:

• Viscosity waa cabbirka caabbinta dareeraha qulqulka. Xaaladda xalalka CMC, viscosity waxaa saameeya arrimo ay ka mid yihiin xoojinta polymer, heerka beddelka (DS), miisaanka kelli, pH, heerkulka, iyo heerka xiirid.
• Viscosity ee xalalka CMC waxaa sida caadiga ah lagu cabbiraa iyadoo la isticmaalayo viskometer, kaas oo quseeya cadaadiska xiirid ee dareeraha oo cabbira isbeddelka ka dhashay ama heerka socodka.

2. Qalab iyo Reagen:

• Muunad heerka-cunto sodium karboxymethyl cellulose (CMC).
• Biyo nadiif ah.
• Viscometer (tusaale, viskometer Brookfield, rotational ama capillary viscometer).
• Spindle ku habboon kala duwanaanshaha viscosity ee muunada.
• Qubeyska biyaha ee heerkulka lagu xakameeyo ama qolka kulaylka.
• Kiciya ama kicinta birta.
• Beakers ama koobabka muunada.
• Saacadda joogsiga ama saacadda.

3. Habka:

1. Tusaalaha Diyaarinta:
   • U diyaari xalal taxane ah oo CMC ah oo leh xaddi kala duwan (tusaale, 0.5%, 1%, 2%, 3%) ee biyaha saafiga ah. Isticmaal dheellitir si aad u miisaanto qiyaasta ku habboon ee budada CMC oo si tartiib tartiib ah ugu dar biyaha adigoo walaaqaya si aad u hubiso kala firdhisanaan buuxda.
   • Oggolow xalalka CMC inay fuuq baxaan oo isku simaan muddo ku filan (tusaale, 24 saacadood) si loo hubiyo fuuq-baxa iyo xasilloonida isku midka ah.
2. Dejinta Qalabka:
   • U cabbir viscometerka sida waafaqsan tilmaamaha soo-saaraha adoo isticmaalaya dareeraha tixraaca viscosity-ga caadiga ah.
   • U deji viscometer-ka xawaaraha ku habboon ama kala duwanaanta heerka xiirta ee viscosity-ka la filayo ee xalalka CMC.
   • Ku sii kululee fiiskootarka iyo dunta birta heerkulka tijaabada la rabo adiga oo isticmaalaya qubeyska heerkulka lagu xakameeyo ama qolka kulaylka.
3. Cabbirka:
   • Ku buuxi koobka muunada ama digsi qaboojiyaha xalka CMC si loo tijaabiyo, adiga oo hubinaya in xadhiggu si buuxda ugu dhex milmay muunadda.
   • Ku dheji xadhigga muunadda, adigoo ka taxadaraya inaad soo bandhigto xumbo hawo.
   • Bilow viscometerka una ogolow in dunidu uu ku wareego xawliga la cayimay ama heerka xiirta muddo go'an (tusaale, 1 daqiiqo) si loo gaadho xaalad joogto ah.
   • Ku duub akhriska viscosity ee ka muuqda muuqalka Ku celi cabbirka xal kasta oo CMC ah iyo heerar kala duwan oo xiirid haddii loo baahdo.
4. Falanqaynta Xogta:
   • Shirqo qiyamka viscosity ka dhanka ah fiirsashada CMC ama heerka xiirid si loo dhaliyo qalooca viscosity.
   • Xisaabi qiyamka viscosity ee muuqda heerar gaar ah oo xiirid ama uruurin isbarbardhigga iyo falanqaynta.
   • Go'aanso hab-dhaqanka rheological ee xalalka CMC (tusaale, Newtonian, pseudoplastic, thixotropic) oo ku salaysan qaabka qalloocyada viscosity iyo saamaynta heerka xiirid ee viscosity.
5. Fasiraadda:
   • Qiimayaasha viscosity-ka sare waxay muujinayaan iska caabin weyn oo socodka iyo sifooyinka dhumuc weyn ee xalka CMC.
   • Habdhaqanka viscosity ee xalalka CMC way kala duwanaan kartaa iyadoo ku xidhan arrimo ay ka mid yihiin fiirsiga, heerkulka, pH, iyo heerka xiirid. Fahamka arrimahan ayaa muhiim u ah wanaajinta waxqabadka CMC ee codsiyada cuntada gaarka ah.

4. Tixgelin:

• Hubi hagaajinta saxda ah iyo dayactirka viscometerka si loo cabbiro sax ah oo la isku halayn karo.
• Xakamee xaaladaha tijaabada (tusaale, heerkulka, heerka xiirid) si loo yareeyo kala duwanaanshiyaha iyo hubinta soo saarista natiijooyinka.
• Xaqiiji habka adigoo isticmaalaya heerarka tixraaca ama falanqaynta isbarbardhigga hababka kale ee la ansaxiyay.
• Samee cabbirada viscosity meelo badan oo ay weheliyaan habaynta ama xaaladaha kaydinta si loo qiimeeyo xasilloonida iyo ku habboonaanta codsiyada loogu talagalay.

Iyadoo la raacayo habkan tijaabada ah, viscosity of sodium carboxymethyl cellulose (CMC) xalalka cuntada si sax ah ayaa loo go'aamin karaa, bixinta macluumaad qiimo leh oo loogu talagalay samaynta, xakamaynta tayada, iyo hagaajinta habka warshadaha cuntada.
