Ukusetshenziswa kwe-sodium carboxymethyl cellulose kanye ne-hydroxyethyl cellulose emikhiqizweni yamakhemikhali yansuku zonke

I-Carboxymethylcellulose sodium (CMC-Na) iyinto ephilayo, i-carboxymethylated derivative of cellulose, kanye nenhlaka 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.

Uma ingathathi hlangothi noma i-alkaline, isisombululo siwuketshezi olune-viscosity ephezulu.Izinzile emithini, ukukhanya nokushisa.Nokho, ukushisa kukhawulelwe kuma-80°C, futhi uma kushisa isikhathi eside ngaphezu kuka-80°C, i-viscosity izokwehla futhi izobe ingancibiliki emanzini.

I-sodium carboxymethyl cellulose nayo iwuhlobo lwe-thickener.Ngenxa yezakhiwo zayo ezinhle zokusebenza, isetshenziswe kabanzi embonini yokudla, futhi iye yakhuthaza nokuthuthukiswa okusheshayo nokunempilo kwemboni yokudla ngezinga elithile.Isibonelo, ngenxa yomphumela wayo wokuqina kanye ne-emulsifying, ingasetshenziswa ukuzinzisa iziphuzo ze-yogurt nokwandisa 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 ithuthukise ukunambitheka.

Ngenxa yokuthi inomphumela othile we-gel, kunenzuzo ekudleni ukwenza i-gel kangcono, ngakho-ke ingasetshenziswa ukwenza i-jelly ne-jam;ingasetshenziswa futhi njengendwangu edliwayo yokunamathela, ihlanganiswe nezinye izingqimba, futhi isabalale Kwezinye izindawo zokudla, ingagcina ukudla kukusha kakhulu, futhi ngenxa yokuthi kuyimpahla edliwayo, ngeke kubangele imiphumela emibi kumuntu. impilo.Ngakho-ke, i-CMC-Na yezinga lokudla, njengesengezo sokudla esifanele, isetshenziswa kabanzi ekukhiqizeni ukudla embonini yokudla.

IHydroxyethylcellulose (HEC), ifomula yamakhemikhali (C2H6O2)n, iyi-fibrous emhlophe noma ekhanyayo, engenaphunga, eqinile engenabuthi noma eyimpuphu, eyakhiwe nge-alkaline cellulose ne-ethylene oxide (noma i-chlorohydrin) Ilungiselelwe ukusabela kwe-etherification, ingeyokungewona i-ionic soluble cellulose ethers.Ngoba i-HEC inezici ezinhle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, ukubopha, ukwenza ifilimu, ukuvikela umswakama nokuhlinzeka nge-colloid evikelayo.

Incibilika kalula emanzini ngo-20°C. Ayincibiliki kuzincibilikisi ezivamile eziphilayo.Inemisebenzi yokujiya, ukumisa okwesikhashana, ukubopha, ukufaka emulsifying, ukuhlakaza, nokugcina umswakama.Izixazululo kumabanga ahlukene we-viscosity zingalungiswa.Inoncibilika kahle kasawoti kuma-electrolyte.

I-viscosity ishintsha kancane kububanzi bevelu engu-PH 2-12, kodwa i-viscosity yehla ngale kwalolu bubanzi.Inezici zokuqina, ukumisa, ukubopha, i-emulsifying, ukusabalalisa, ukugcina umswakama nokuvikela i-colloid.Izixazululo kumabanga ahlukene we-viscosity zingalungiswa.
