Sodium Carboxymethyl Cellulose Solubility

Sodium Carboxymethyl Cellulose Solubility

Sodium carboxymethyl cellulose (CMC) waa polymer biyo-milmi leh oo laga soo qaatay cellulose, polysaccharide dabiici ah oo laga helo gidaarada unugyada dhirta. Ku milanka CMC ee biyaha waa mid ka mid ah sifooyinkeeda muhiimka ah waxaana saameeya arrimo kala duwan, oo ay ku jiraan heerka beddelka (DS), miisaanka unugyada, pH, heerkulka, iyo kicinta. Halkan waxaa ah sahaminta milanka sodium carboxymethyl cellulose:

1. Darajada Beddelka (DS):

  • Heerka beddelka waxa loola jeedaa celceliska tirada kooxaha karboksymetyl unugga gulukoosta ee silsiladda cellulose. Qiimaha sare ee DS wuxuu muujinayaa heer aad u weyn oo beddelaad ah iyo kororka milanka biyaha.
  • CMC oo leh qiyamka sare ee DS waxay u janjeertaa inay lahaato milmi biyo ka wanaagsan sababtoo ah uruurinta sare ee kooxaha karboksymethyl hydrophilic oo ay weheliso silsiladda polymer.

2. Miisaanka Molecular:

  • Miisaanka molecular ee CMC wuxuu saameyn karaa ku milanka biyaha. Miisaanka unugyadu sareeyo CMC waxa laga yaabaa inuu muujiyo heerar kala dirid oo gaabis ah marka la barbar dhigo darajooyinka miisaanka kelliyada hoose.
  • Si kastaba ha ahaatee, mar la milmo, labadaba miisaanka kelli ee sare iyo kan hoose CMC caadi ahaan waxay sameeyaan xalal leh sifooyinka viscosity la mid ah.

3. pH:

  • CMC waa mid xasiloon oo ku milmi badan pH ballaaran, sida caadiga ah laga bilaabo acidic ilaa xaaladaha alkaline.
  • Si kastaba ha ahaatee, qiimaha pH ee aadka u daran ayaa laga yaabaa inay saameeyaan milanka iyo xasilloonida xalalka CMC. Tusaale ahaan, xaaladaha acidic waxay protonate karaan kooxaha karboksylka, yaraynta milanka, halka xaaladaha alkaline ay u horseedi karaan hydrolysis iyo hoos u dhaca CMC.

4. Heerkulka:

  • Solubility ee CMC guud ahaan waxay kordhisaa heerkulka. Heerkulka sare wuxuu fududeeyaa habka kala dirida wuxuuna keenaa fuuq-bax degdeg ah ee qaybaha CMC.
  • Si kastaba ha ahaatee, xalalka CMC waxa laga yaabaa inay maraan xaalufka kulaylka ee heerkul sare, taas oo horseedaysa hoos u dhaca viscosity iyo xasiloonida.

5. Kicin:

  • Kicinta ama isku darka waxay wanaajisaa kala dirida CMC ee biyaha iyadoo kordhinaysa xidhiidhka ka dhexeeya qaybaha CMC iyo molecules biyaha, sidaas awgeed waxay dardar galinaysaa habka fuuq-celinta.
  • Kacsi ku filan ayaa inta badan loo baahan yahay si loo gaaro kala diri buuxda ee CMC, gaar ahaan darajooyinka miisaanka kelli ee sare ama xalalka xoogga leh.

6. Isku-duubnaanta milixda:

  • Joogitaanka milixdu, gaar ahaan kala-duwanaanta ama cations-ka kala duwan sida ion calcium, waxay saameyn kartaa milanka iyo xasilloonida xalalka CMC.
  • Isku-duubnaanta milixdu waxay u horseedi kartaa samaynta dhismooyin aan la milmi karin ama jeel, hoos u dhigista milanka iyo waxtarka CMC.

7. Isku-duubnaanta Polymer:

  • Solubility CMC sidoo kale waxaa saameyn ku yeelan kara xoojinta polymerka ee xalka. Heerarka sare ee CMC ayaa laga yaabaa inay u baahdaan waqtiyo kala diris dheer ama kacsanaan kordhay si loo gaaro fuuqbax dhamaystiran.

Marka la soo koobo, sodium carboxymethyl cellulose (CMC) waxay soo bandhigaysaa milmi biyo aad u wanaagsan oo ku saabsan xaalado kala duwan, taasoo ka dhigaysa wax lagu daro warshado kala duwan. Solubility ee CMC waxaa saameeya arrimo ay ka mid yihiin heerka beddelka (DS), miisaanka kelli, pH, heerkulka, kicinta, xoojinta milixda, iyo diiradda polymer. Fahamka arrimahan ayaa muhiim u ah wanaajinta habaynta iyo waxqabadka alaabta ku salaysan CMC ee codsiyada kala duwan.
