I-Sodium Carboxymethyl Cellulose (CMC) uMgangatho weMaterial

I-Sodium Carboxymethyl Cellulose (CMC)iphuma kwiselulosi kunye nemathiriyeli yendalo yepolymer eneempawu ezigqwesileyo ezifana nokunyibilika kwamanzi, i-viscosity kunye nokuqina. Ngenxa biocompatibility yayo elungileyo, non-ityhefu kunye degradability, CMC isetyenziswa ngokubanzi ukutya, amayeza, imichiza mihla, papermaking, impahla, ukutsalwa ioli kunye namanye amashishini. Njengomsebenzi obalulekileyo osebenzayo, umgangatho womgangatho we-CMC udlala indima ebalulekileyo ekhokelayo kwiinkalo ezahlukeneyo.

1. Iipropati ezisisiseko ze-CMC

Ubume bemichiza ye-AnxinCel®CMC kukuzisa amaqela e-carboxymethyl (-CH2COOH) kwiimolekyuli ze-cellulose, ukwenzela ukuba ibe ne-solubility yamanzi. Iimpawu zayo eziphambili ziquka:

Ukunyibilika kwamanzi: I-CMC inokwenza isisombululo se-viscous ecacileyo emanzini kwaye isetyenziswa ngokubanzi njenge-thickener okanye i-stabilizer kwiimveliso ezahlukeneyo zolwelo.

Ukuqina: I-CMC ine-viscosity ephezulu kwaye inokunyusa ngokufanelekileyo ukuhambelana kolwelo kunye nokunciphisa ulwelo.

Uzinzo: I-CMC ibonisa uzinzo oluhle lweekhemikhali kwii-pH ezahlukeneyo kunye nobushushu.

I-Biodegradability: I-CMC iphuma kwi-cellulose yendalo enokubola okulungileyo kunye nokusebenza okubalaseleyo kokusingqongileyo.

2. Imigangatho yomgangatho weCMC

Imigangatho yomgangatho weCMC iyahluka ngokwemimandla eyahlukeneyo yokusetyenziswa kunye neemfuno zokusebenza. Oku kulandelayo zezinye zeeparamitha zomgangatho ophambili:

Imbonakalo: I-CMC kufuneka ibe mhlophe okanye i-off-white amorphous powder okanye iigranules. Makungabikho ukungcola okubonakalayo kunye nezinto zangaphandle.

Isiqulatho sokufuma: Isiqulatho sokufuma se-CMC ngokubanzi asidluli kwi-10%. Ukufuma okugqithisileyo kuya kuchaphazela ukuzinza kokugcinwa kwe-CMC kunye nokusebenza kwayo kwizicelo.

Viscosity: Viscosity yenye yezalathi ezibalulekileyo CMC. Ngokuqhelekileyo kugqitywa ngokulinganisa i-viscosity yesisombululo sayo samanzi nge-viscometer. Okukhona i-viscosity iphezulu, kokukhona isiphumo sokuqina se-CMC. Ugxininiso olwahlukileyo lwezisombululo ze-CMC zineemfuno ezahlukeneyo ze-viscosity, ngokuqhelekileyo phakathi kwe-100-1000 mPa·s.

IsiGangatho sokuTshintshela (ixabiso le-DS): iDegree of Substitution (DS) yenye yeempawu ezibalulekileyo zeCMC. Imele inani eliqhelekileyo le-carboxymethyl substitution kwiyunithi nganye yeglucose. Ngokuqhelekileyo, ixabiso le-DS liyafuneka ukuba libe phakathi kwe-0.6-1.2. Ixabiso eliphantsi kakhulu le-DS liya kuchaphazela ukunyibilika kwamanzi kunye nesiphumo sokuqina kwe-CMC.

Ubumuncu okanye ixabiso le-pH: Ixabiso le-pH lesisombululo se-CMC lifuneka ngokubanzi ukuba libe phakathi kwe-6-8. Ixabiso le-pH eliphantsi kakhulu okanye eliphezulu kakhulu kunokuchaphazela uzinzo kunye nesiphumo sokusetyenziswa kwe-CMC.

Umxholo wothuthu: Umxholo wothuthu ngumxholo we-inorganic matter kwi-CMC, edla ngokufunwa ukuba ungadluli kwi-5%. Isiqulatho sothuthu esiphezulu kakhulu sinokuchaphazela ukunyibilika kweCMC kunye nomgangatho wesicelo sokugqibela.

Ukunyibilika: I-CMC kufuneka ichithwe ngokupheleleyo emanzini kwiqondo lobushushu begumbi ukwenza isisombululo esicacileyo, esimisiweyo. I-CMC enonyibiliko olulambathayo inokuqulatha ukungcola okunganyibilikiyo okanye i-cellulose ekumgangatho ophantsi.

Umxholo wentsimbi enzima: Umxholo wentsimbi enzima kwi-AnxinCel®CMC kufuneka ihambelane nemigangatho yelizwe okanye yoshishino. Ngokuqhelekileyo kufunwa ukuba umxholo opheleleyo weentsimbi ezinzima awuyi kudlula i-0.002%.

Izalathi zeMikhrobhayoloji: I-CMC kufuneka ihlangabezane nemigangatho yomlinganiselo wemicrobial. Ngokuxhomekeke kusetyenziso, i-CMC yokutya-grade, i-CMC ye-pharmaceutical-grade, njl. ifuna ulawulo olungqongqo lwe-microorganisms ezinobungozi ezifana neebhaktheriya, i-mold, kunye ne-E. coli.

3. Imigangatho yokusetyenziswa kwe-CMC

Imimandla eyahlukeneyo ineemfuno ezahlukeneyo ze-CMC, ngoko ke imigangatho yesicelo ethile kufuneka iqulunqwe. Imigangatho yesicelo eqhelekileyo ibandakanya:

Ishishini lokutya: I-CMC ye-Food-grade isetyenziselwa ukuqina, ukuzinzisa, i-emulsification, njl., kwaye kufuneka ihlangabezane nemigangatho yokhuseleko lokutya, efana ne-non-toxic, engenabungozi, i-non-allergenic, kwaye inokunyibilika kakuhle kwamanzi kunye ne-viscosity. I-CMC ingasetyenziselwa ukunciphisa umxholo wamafutha kunye nokuphucula incasa kunye nokuthungwa kokutya.

Imboni yamachiza: Njengomxhasi oqhelekileyo weziyobisi, i-CMC ye-pharmaceutical-grade idinga ulawulo olungqongqo lwezinto ezingcolileyo, umxholo we-microbial, ukungabikho kwetyhefu, ukungabikho kwe-allergenicity, njl.

Iikhemikhali zemihla ngemihla: Kwii-cosmetics, i-detergents kunye nezinye iikhemikhali zemihla ngemihla, i-CMC isetyenziswe njenge-thickener, i-stabilizer, i-agent yokumisa, njl., kwaye kufuneka ibe ne-solubility yamanzi, i-viscosity kunye nokuzinza.

Umzi-mveliso wePapermaking: I-CMC isetyenziswa njenge-adhesive, i-ejenti yokwaleka, njl. kwinkqubo yokwenza iphepha, ifuna i-viscosity ephezulu, ukuzinza kunye neqondo elithile lokulawula ukufuma.

Oilfield exploitation: I-CMC isetyenziswa njengesongezo solwelo kwi-oilfield drilling fluids ukunyusa i-viscosity kunye nokuphucula ulwelo. Ezo zicelo zineemfuno eziphezulu ze-solubility kunye ne-viscosity-ukwandisa isakhono se-CMC.

Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe,CMC, njengempahla yepolymer yendalo, iya kuqhubeka nokwandisa iindawo zayo zesicelo. Xa kuqulunqwa imigangatho yomgangatho wezinto ze-CMC, ngaphezu kokuqwalasela iimpawu zayo zomzimba kunye neekhemikhali, kuyafuneka ukuba kuqwalaselwe ngokubanzi iimfuno zesicelo sokuqinisekisa ukuba inokuhlangabezana neemfuno zemimandla eyahlukeneyo yezoshishino. Ukuqulunqa imigangatho ecacileyo kunye necacileyo yindlela ebalulekileyo yokuqinisekisa umgangatho kunye nesiphumo sokusetyenziswa kweemveliso ze-AnxinCel®CMC, kwaye ingundoqo ekuphuculeni ukukhuphisana kwemarike yezinto ze-CMC.
