Factory Direct Supply Pheej Yig Cellulose CMC

Carboxymethyl Cellulose (CMC) yog ib qho khoom noj khoom haus ntxiv, thiab nws cov ntsev ntsev (sodium carboxymethyl cellulose) yog siv los ua phom thiab muab tshuaj txhuam.Sodium carboxymethyl cellulose tov: boiling dej tab sis tus nqi yuav tsum tsis txhob ntau tshaj 0.5% - 0.7% sodium carboxymethyl cellulose tov coj sodium carboxymethyl cellulose 0.5g, ntxiv dej 100ml, cua sov thiab boiling, kom txog thaum tag nrho yaj.Ntxiv cov dej me me kom them nyiaj rau evaporation ua ntej boiling.(1) Nws tus kheej ua nyias txheej txheej nrog sodium carboxymethyl cellulose aqueous tov (0.2% - 0.5%) tus nqi tsim nyog rau hauv ib qho sib npaug sib npaug ntawm cov iav phaj.Thawj thawj zaug, 1.85g silica gel thiab 5ml sodium carboxymethyl cellulose aqueous tov tau muab thiab muab tso rau hauv lub tais mis.Rau qhov so, 1.11g silica gel thiab 3ml sodium carboxymethyl cellulose aqueous tov tau noj txhua zaus.Sib tsoo rau tib qho kev taw qhia kom txog thaum tsis muaj npuas, cov hnoos qeev tuaj yeem yog linear.Natural cellulose yog qhov dav tshaj plaws thiab muaj ntau polysaccharide nyob rau hauv cov xwm.Cov kev hloov kho tam sim no ntawm cellulose feem ntau tsom rau etherification thiab esterification.Carboxymethylation yog ib qho ntawm cov txheej txheem etherification.Cellulose tom qab carboxymethylation carboxymethyl cellulose (CMC), nws cov tshuaj aqueous muaj thickening, film forming, bonding, water retention, colloidal tiv thaiv, emulsification thiab ncua kev kawm ntawv, dav siv nyob rau hauv roj av, zaub mov, tshuaj, textile thiab ntawv kev lag luam, yog ib qho tseem ceeb tshaj plaws. cellulose ether
