I-sodium carboxymethyl cellulose

I-sodium carboxymethyl cellulose (CMC-Na) iphuma ku-carboxymethylated ku-cellulose futhi iyishingamu ye-ionic cellulose ebaluleke kakhulu. I-sodium carboxymethyl cellulose imvamisa iyinhlanganisela ye-anionic polymer elungiswa ngokusabela i-cellulose yemvelo nge-caustic alkali ne-monochloroacetic acid, enesisindo samangqamuzana asuka ezinkulungwaneni ezimbalwa kuya ezigidini. I-CMC-Na iyimpushana emhlophe noma i-granular, ayinaphunga, ayinambitheki, i-hygroscopic, kulula ukuyihlakaza emanzini ukuze yakhe isixazululo se-colloidal esobala.

2. Izakhiwo zomzimba namakhemikhali

I-CMC-Na ngempushana ephuzi, emhlophe ukuya kokuphaphathekile, eyimbudumbudu noma ene-fibrous, i-hygroscopicity eqinile, encibilika kalula emanzini, futhi isixazululo siwuketshezi olune-viscosity ephezulu uma lungathathi hlangothi noma lune-alkaline. Izinzile emithini, ukukhanya nokushisa. Kodwa-ke, ukushisa kunqunyelwe ku-80 ° C, futhi uma kushisa isikhathi eside ngaphezu kuka-80 ° C, i-viscosity izokwehla futhi izobe ingancibiliki emanzini. Ukuminyana kwayo okuhlobene ngu-1.60, futhi ukuminyana kwesihlobo sama-flakes ngu-1.59. Inkomba ye-refractive ingu-1.515. Iba nsundu uma ishiselwa kufika ku-190-205°C, futhi i-carbonizes uma ishise ibe ngu-235-248°C. Ukuncibilika kwayo emanzini kuncike ezingeni lokushintsha. Ayincibiliki ku-asidi notshwala, akukho mvula uma kunosawoti. Akulula ukuvutshelwa, inamandla aqinile emulsifying ku-oyela ne-wax, futhi ingagcinwa isikhathi eside.

3. Isicelo esikhulu

Isetshenziswa kakhulu embonini kawoyela yokumba udaka, okokusula okokwenziwa, umakhi wezihlanzi, ukuphrinta izindwangu kanye ne-ejenti yokudaya, i-colloidal tackifier encibilika emanzini emikhiqizweni yansuku zonke yamakhemikhali, i-tackifier kanye ne-emulsifier embonini yezemithi, ukuqina kwemboni yezokudla, i-adhesive ye-ceramic. imboni, i-industrial paste, i-ejenti yokulinganisa embonini yephepha, njll. Isetshenziswa njenge-flocculant ekuhlanzeni amanzi, ikakhulukazi esetshenziselwa ukwelashwa kwamanzi angcolile, okungakhuphula okuqukethwe okuqinile kwekhekhe lokuhlunga.

I-sodium carboxymethyl cellulose nayo iwuhlobo lwe-thickener. Ngenxa yezakhiwo zayo ezinhle zokusebenza, iye yasetshenziswa kakhulu embonini yokudla, futhi iye yakhuthaza nokuthuthukiswa okusheshayo nokunempilo kwemboni yezokudla ngezinga elithile. Isibonelo, ngenxa yomphumela wayo wokuqina kanye ne-emulsifying, ingasetshenziswa ukuzinzisa iziphuzo ze-yogurt futhi kwandiswe i-viscosity yesistimu ye-yogurt; ngenxa yezindawo zayo ezithile ze-hydrophilicity kanye ne-rehydration, ingasetshenziswa ukuthuthukisa ukusetshenziswa kwe-pasta njengesinkwa nesinkwa esishisayo. ikhwalithi, yelula impilo yeshalofu yemikhiqizo ye-pasta, futhi uthuthukise ukunambitheka; ngoba inomphumela othile we-gel, ivumela ukwakheka okungcono kwejeli ekudleni, ngakho-ke ingasetshenziswa ukwenza i-jelly ne-jam; ingasetshenziswa futhi njengefilimu enamathelayo edliwayo Impahla ihlanganiswe nezinye izingqimba futhi ifakwe ebusweni bokunye ukudla, okungagcina ukudla kusha kuze kube sezingeni eliphezulu, futhi ngenxa yokuthi kuyizinto ezidliwayo, ngeke kubangele okubi. imiphumela empilweni yomuntu. Ngakho-ke, i-CMC-Na yezinga lokudla, njengesengezo sokudla esifanele, isetshenziswa kabanzi ekukhiqizeni ukudla embonini yokudla.
