I-Carboxymethyl Cellulose (isiNgisi: I-Carboxymethyl Cellulose, i-CMC ngamafuphi) iyisengezo sokudla esisetshenziswa kakhulu, futhi usawoti wayo we-sodium (sodium carboxymethyl cellulose) uvame ukusetshenziswa njenge-thickener nokunamathisela.
I-Carboxymethyl cellulose ibizwa nge-industrial monosodium glutamate, esetshenziswa kabanzi ekukhiqizeni izimboni futhi iletha inani elikhulu lokusetshenziswa emikhakheni ehlukahlukene yokukhiqiza.I-Carboxymethyl cellulose iyimpuphu, engenabuthi, kodwa kulula ukuyincibilika emanzini.Iyancibilika emanzini abandayo nasemanzini ashisayo, kodwa ayincibiliki ezihlangwini zemvelo.Izoba uketshezi lwe-viscous ngemuva kokuqedwa, kepha i-viscosity izohluka ngenxa yokukhuphuka nokwehla kwezinga lokushisa.Ngenxa yezakhiwo zayo ezikhethekile, kunezidingo eziningi ezikhethekile zokugcina nokuthutha.
Izakhiwo zomzimba namakhemikhali
I-Carboxymethyl cellulose yinto emhlophe noma ephuzi ekhanyayo, engenaphunga, ayinambitheki, ama-hygroscopic granules, impushana noma imicu emihle.
※Pukulungiswa
I-Carboxymethylcellulose ihlanganiswa ukusabela kwe-base-catalyzed ye-cellulose ne-chloroacetic acid.Amaqembu e-polar (organic acid) e-carboxyl enza i-cellulose inyibilike futhi isebenze ngamakhemikhali.Ngemva kokusabela kokuqala, ingxube ewumphumela yakhiqiza cishe u-60% CMC kanye no-40% kasawoti (i-sodium chloride ne-sodium glycolate).Umkhiqizo ubizwa ngokuthi i-CMC yezimboni yezihlanzi.Lawa masawoti asuswa kusetshenziswa inqubo eyengeziwe yokuhlanza ukuze kukhiqizwe i-CMC emsulwa ukuze isetshenziswe ekudleni, emithini yemithi kanye nakuma-dentfrices (i-toothpaste).Amabanga aphakathi nendawo “ahlanziwe semi-purified” nawo akhiqizwa, avame ukusetshenziswa ekufakweni kwephepha okufana nokubuyiselwa kwemibhalo egciniwe.Izakhiwo ezisebenzayo ze-CMC zincike ezingeni lokushintshwa kwesakhiwo se-cellulose (okungukuthi, mangaki amaqembu e-hydroxyl abamba iqhaza ekuphenduleni esikhundleni), kanye nobude beketanga lesakhiwo somgogodla we-cellulose kanye nezinga lokuhlanganisa komgogodla we-cellulose. .I-Carboxymethyl esikhundleni.
※Aisicelo
I-Carboxymethylcellulose isetshenziswa ekudleni njenge-viscosity modifier noma i-thickener ngaphansi kwenombolo E466 noma i-E469 (nge-enzymatic hydrolysis) kanye nokusimamisa ama-emulsion emikhiqizweni eyahlukene, kuhlanganise no-ayisikhilimu.Iphinde ibe yingxenye yemikhiqizo eminingi okungeyona eyokudla efana nokuxubha amazinyo, okokuthambisa, amaphilisi okudla, opende abasuselwe emanzini, okokuhlanza, izinto zokulinganisa izindwangu, ukupakishwa okuphinda kusetshenziswe okushisayo kanye nemikhiqizo yamaphepha eyahlukene.Isetshenziswa ngokuyinhloko ngoba i-viscosity ephezulu, ayinabo ubuthi futhi ngokuvamile ibhekwa njenge-hypoallergenic njengoba imicu yomthombo oyinhloko i-softwood wood pulp noma i-cotton linters.I-Carboxymethylcellulose isetshenziswa kakhulu ekudleni okungenayo i-gluten nokuncishisiwe okunamafutha.Ezihlahleni zokuwasha, isetshenziswa njengenhlabathi elenga i-polymer eklanyelwe ukufaka ukotini nezinye izindwangu ze-cellulosic, okudala umgoqo okhokhiswa kabi enhlabathini yotshwala bokugeza.I-Carboxymethylcellulose isetshenziswa njenge-lubricant ezinyembezini zokwenziwa.I-Carboxymethylcellulose iphinde isetshenziswe njenge-ejenti yokuqina, isibonelo, embonini yokumba uwoyela, lapho iyingxenye yodaka lokumba, lapho isetshenziswa khona njenge-modifier viscosity kanye ne-ejenti yokugcinwa kwamanzi.Isibonelo, i-sodium CMC (Na CMC) yasetshenziswa njengesilawuli esingalungile sokulahlekelwa izinwele konogwaja.Izindwangu ezinithiwe ezenziwe nge-cellulose, ezifana nekotini noma i-viscose rayon, zingaguqulwa zibe ama-CMC futhi zisetshenziswe emisebenzini yezokwelapha ehlukahlukene.
