I-Sodium Carboxymethyl Cellulose (CMC)yi-derivative ye-cellulose kunye nezinto ze-polymer zendalo ezineempawu ezintle ezifana nokunyibilika kwamanzi, i-viscosity kunye nokuqina. Ngenxa yokuhambelana kwayo kakuhle kwezinto eziphilayo, ukungabi natyhefu kunye nokubola, i-CMC isetyenziswa kakhulu ekutyeni, kumayeza, kwiikhemikhali zemihla ngemihla, ekwenzeni amaphepha, kwiimpahla, ekutsaleni ioyile nakwamanye amashishini. Njengezinto ezibalulekileyo ezisebenzayo, umgangatho womgangatho we-CMC udlala indima ebalulekileyo yokukhokela kwiinkalo ezahlukeneyo.
1. Iimpawu ezisisiseko ze-CMC
Ulwakhiwo lweekhemikhali lwe-AnxinCel®CMC kukungenisa amaqela e-carboxymethyl (-CH2COOH) kwiimolekyuli ze-cellulose, ukuze ibe nokunyibilika kakuhle kwamanzi. Iimpawu zayo eziphambili ziquka:
Ukunyibilika kwamanzi: I-CMC inokwenza isisombululo esicacileyo nesiqinileyo emanzini kwaye isetyenziswa kakhulu njengesithambisi okanye isizinzisi kwiimveliso ezahlukeneyo zolwelo.
Ukuqina: I-CMC inoburhabaxa obuphezulu kwaye inokunyusa ngokufanelekileyo ukuhambelana kolwelo kwaye inciphise ukunyibilika kolwelo.
Uzinzo: I-CMC ibonisa uzinzo oluhle lweekhemikhali kwiindidi ezahlukeneyo ze-pH kunye nobushushu.
Ukubola kwe-biogradability: I-CMC yimveliso ye-cellulose yendalo enokonakala kwe-biogradability okuhle kunye nokusebenza kakuhle kokusingqongileyo.
2. Imigangatho yomgangatho we-CMC
Imigangatho yomgangatho ye-CMC iyahluka ngokweenkalo ezahlukeneyo zokusetyenziswa kunye neemfuno zokusebenza. Ezi zilandelayo zezinye zeeparamitha eziphambili zomgangatho womgangatho:
Inkangeleko: I-CMC mayibe ngumgubo okanye iigranule ezimhlophe okanye ezingabonakali kakuhle. Akufuneki kubekho ukungcola okubonakalayo kunye nezinto zangaphandle.
Ubungakanani bokufuma: Ubungakanani bokufuma beCMC ngokubanzi abudluli kwi-10%. Ubuninzi bokufuma buya kuchaphazela uzinzo lokugcina lweCMC kunye nokusebenza kwayo kwiindlela ezisetyenziswayo.
Ukuqina: Ukuqina yenye yezona zinto zibalulekileyo ze-CMC. Ihlala imiselwa ngokulinganisa ukuqina kwesisombululo sayo samanzi nge-viscometer. Okukhona ukuqina kuphezulu, kokukhona isiphumo sokuqina se-CMC siqina. Uxinzelelo olwahlukeneyo lwezisombululo ze-CMC luneemfuno ezahlukeneyo zokuqina, ngesiqhelo phakathi kwe-100-1000 mPa·s.
Inqanaba lokuTshintsha (ixabiso le-DS): Inqanaba lokuTshintsha (i-DS) yenye yeempawu ezibalulekileyo ze-CMC. Imele inani eliqhelekileyo le-carboxymethyl substitutions kwiyunithi nganye yeglucose. Ngokubanzi, ixabiso le-DS kufuneka libe phakathi kwe-0.6-1.2. Ixabiso le-DS eliphantsi kakhulu liya kuchaphazela ukunyibilika kwamanzi kunye nefuthe lokutyeba kwe-CMC.
Ixabiso le-asidi okanye i-pH: Ixabiso le-pH yesisombululo se-CMC ngokubanzi kufuneka libe phakathi kwe-6-8. Ixabiso le-pH eliphantsi kakhulu okanye eliphezulu kakhulu linokuchaphazela uzinzo kunye nempembelelo yokusetyenziswa kwe-CMC.
Umxholo wothuthu: Umxholo wothuthu ngumxholo wezinto ezingaphiliyo kwi-CMC, odla ngokufuneka ungadluli kwi-5%. Umxholo wothuthu ophezulu kakhulu unokuchaphazela ukunyibilika kwe-CMC kunye nomgangatho wokusetyenziswa kokugqibela.
Ukunyibilika: I-CMC kufuneka inyibilike ngokupheleleyo emanzini kubushushu begumbi ukuze yenze isisombululo esicacileyo nesixhonyiweyo. I-CMC enokunyibilika kakubi inokuba nokungcola okunganyibilikiyo okanye i-cellulose ekumgangatho ophantsi.
Umxholo wesinyithi esinzima: Umxholo wesinyithi esinzima kwi-AnxinCel®CMC kufuneka uhambelane nemigangatho yesizwe okanye yeshishini. Ngokuqhelekileyo kufuneka ukuba umxholo uwonke wesinyithi esinzima ungadluli kwi-0.002%.
Iimpawu ze-microbiological: I-CMC kufuneka ihlangabezane nemigangatho yomda weentsholongwane. Ngokuxhomekeke ekusetyenzisweni, i-CMC yodidi lokutya, i-CMC yodidi lwamayeza, njl.njl. zifuna ulawulo olungqongqo lomxholo weentsholongwane eziyingozi ezifana neebhaktheriya, ukungunda, kunye ne-E. coli.
3. Imigangatho yokusetyenziswa kwe-CMC
Amasimi ahlukeneyo aneemfuno ezahlukeneyo ze-CMC, ngoko ke kufuneka kwenziwe imigangatho ethile yesicelo. Imigangatho yesicelo eqhelekileyo ibandakanya:
Ishishini lokutya: I-CMC yodidi lokutya isetyenziselwa ukuqina, ukuzinzisa, ukuxuba, njl.njl., kwaye iyimfuneko ukuze ihlangabezane nemigangatho yokhuseleko lokutya, efana nokungabi nabungozi, okungenabungozi, okungenabungozi, kwaye inokunyibilika kakuhle emanzini kunye nokuxinana. I-CMC ingasetyenziselwa ukunciphisa umxholo wamafutha kunye nokuphucula incasa kunye nokuthungwa kokutya.
Ishishini leMithi: Njengesixhobo esiqhelekileyo sokongeza amayeza, i-CMC yodidi lwamayeza ifuna ulawulo olungqongqo lokungcola, umxholo weentsholongwane, ukungabi natyhefu, ukungabangeli ukungezwani komzimba, njl. Imisebenzi yayo ephambili ibandakanya ukukhululwa okulawulwayo kwamayeza, ukuqina, izinto zokuncamathelisa, njl.
Iikhemikhali zemihla ngemihla: Kwizinto zokuthambisa, iisepha kunye nezinye iikhemikhali zemihla ngemihla, i-CMC isetyenziswa njengesithambisi, isizinzisi, iarhente yokuxhoma, njl.njl., kwaye iyimfuneko ukuze ibe nokunyibilika kwamanzi, ukuxinana kunye nozinzo olufanelekileyo.
Ishishini lokwenza amaphepha: I-CMC isetyenziswa njenge-glue, i-ejenti yokugquma, njl.njl. kwinkqubo yokwenza amaphepha, ifuna i-viscosity ephezulu, uzinzo kunye nenqanaba elithile lokukwazi ukulawula ukufuma.
Ukusetyenziswa kwe-oyile: I-CMC isetyenziswa njengesongezelelo solwelo kulwelo lokugrumba i-oyile ukwandisa ukutyeba nokuphucula ukutyeba. Usetyenziso olunjalo luneemfuno eziphezulu zokunyibilika kunye nokukwazi ukwandisa ukutyeba kwe-oyile.
Ngophuhliso oluqhubekayo lwesayensi netekhnoloji,I-CMC, njengezinto zepolymer zendalo, iya kuqhubeka nokwandisa iindawo zayo zokusetyenziswa. Xa kuqulunqwa imigangatho yomgangatho wezinto zeCMC, ukongeza ekuqwalaseleni iimpawu zayo zomzimba nezekhemikhali, kuyimfuneko ukuqwalasela ngokupheleleyo iimfuno zayo zokusetyenziswa ukuqinisekisa ukuba inokuhlangabezana neemfuno zamacandelo ahlukeneyo emizi-mveliso. Ukwenza imigangatho eneenkcukacha nezicacileyo yindlela ebalulekileyo yokuqinisekisa umgangatho kunye nefuthe lokusetyenziswa kweemveliso ze-AnxinCel®CMC, kwaye kukwabalulekile ekuphuculeni ukhuphiswano lwemarike lwezinto zeCMC.
