ICarboxymethyl Cellulose (CMC) sisongezo esiqhelekileyo sokutya, kwaye ityuwa yayo yesodium (i-sodium carboxymethyl cellulose) isetyenziswa njengegunk kunye nokuncamathelisa.Isisombululo se-sodium carboxymethyl cellulose: amanzi abilayo kodwa isixa asikwazi ukuba ngaphezu kwe-0.5% - 0.7% isisombululo se-sodium carboxymethyl cellulose thatha i-sodium carboxymethyl cellulose 0.5g, yongeza amanzi 100ml, ukufudumeza kunye nokubilisa, de kuchithwa ngokupheleleyo.Yongeza umlinganiselo omncinci wamanzi ukuhlawulela ukuvela komphunga phambi kokuba ubilise.1Ngethuba lokuqala, i-1.85g ye-silica gel kunye ne-5ml ye-sodium carboxymethyl cellulose isisombululo se-aqueous yathathwa kwaye yafakwa kwisitya sobisi.Kwabanye, i-1.11g silica gel kunye ne-3ml ye-sodium carboxymethyl cellulose isisombululo se-aqueous sathathwa ngexesha ngalinye.Gaya kwicala elifanayo de kungabikho bubble, i-mucus ingaba ngumgca.I-cellulose yendalo yeyona polysaccharide isasazwe kakhulu kwaye ininzi kwindalo.Iindlela zangoku zokuguqula i-cellulose zijolise ikakhulu kwi-etherification kunye ne-esterification.I-Carboxymethylation yenye yeendlela ze-etherification.I-cellulose emva kwe-carboxymethylation carboxymethyl cellulose (CMC), isisombululo sayo samanzi sinokuqina, ukubunjwa kwefilimu, ukudibanisa, ukugcinwa kwamanzi, ukukhuselwa kwe-colloidal, i-emulsification kunye nokumiswa, isetyenziswe ngokubanzi kwi-petroleum, ukutya, amayeza, i-textile kunye neshishini lephepha, yenye yezona zinto zibalulekileyo. i-cellulose ether
I-sodium carboxymethyl cellulose (CMC) yi-anionic cellulose ether, ukubonakala komgubo omhlophe okanye ophuzi kancinci we-flocculent fiber okanye umgubo omhlophe, akukho vumba, ingenancasa, ayinayo ityhefu;I-Soluble emanzini abandayo okanye ashushu, okwenza isisombululo esicacileyo kunye ne-viscosity ethile.Isisombululo singathathi hlangothi okanye i-alkaline encinci, i-insoluble kwi-ethanol, i-ether, i-isopropyl alcohol, i-acetone kunye nezinye i-solvents eziphilayo, kodwa i-soluble kwi-ethanol okanye isisombululo se-acetone esiqulethe i-60% yamanzi.I-hygroscopic kunye ne-photothermal stable, kwaye i-viscosity iyancipha ngokunyuka kweqondo lokushisa.Isisombululo sizinzile kwi-PH 2 ~ 10, kwaye i-PH ingaphantsi kwe-2. Kukho i-precipitates eqinile, kwaye i-viscosity iyancipha xa ixabiso le-PH liphezulu kune-10. Ukushisa kwe-discoloration kwakuyi-227 ℃, ukushisa kwe-carbonization kwakuyi-252 ℃, kunye noxinzelelo lwangaphezulu lwe-2% yesisombululo samanzi sasiyi-71mn / n.
