Ka ʻike o ka sodium carboxymethyl cellulose

Nā waiwai o Sodium Carboxymethyl Cellulose

CMC mea he cellulose derivative me ka glucose polymerization degere o 200-500 a me ka etherification degree o 0.6-0.7. He pauda keʻokeʻo keʻokeʻo a i ʻole mea fibrous, ʻaʻohe ʻala a hygroscopic. ʻO ke degere o ka hoʻololi ʻana o ka hui carboxyl (ke degere o ka etherification) e hoʻoholo i kāna mau waiwai. Ke piʻi ka degere etherification ma luna o 0.3, hiki ke hoʻoheheʻe ʻia i ka hopena alkali. Hoʻoholo ʻia ka viscosity o ka hopena wai e ka pH a me ka degere o ka polymerization. Ke 0.5-0.8 ka degere o ka etherification, ʻaʻole ia e hoʻoheheʻe i ka waika. Hiki ke hoʻoheheʻe ʻia ka CMC i loko o ka wai a lilo i mea hoʻoheheʻe viscous i loko o ka wai, a ʻokoʻa kona viscosity me ka neʻe ʻana a me ka mahana. Paʻa ka mahana ma lalo o 60 ° C, a e emi ana ka viscosity i ka wā i wela ai no ka manawa lōʻihi ma kahi mahana ma luna o 80 ° C.

Ka laulā o ka hoʻohana ʻana i ka sodium carboxymethyl cellulose

Loaʻa iā ia nā hana like ʻole e like me ka thickening, suspending, emulsifying and stabilizing. I ka hana ʻana i ka mea inu, hoʻohana nui ʻia ia ma ke ʻano he mānoanoa no nā mea inu wai wai pulp, ma ke ʻano he emulsification stabilizer no nā mea inu protein a me kahi stabilizer no nā inu yogurt. ʻO ka maʻamau he 0.1% -0.5%.
