I-Sodium Carboxymethyl Cellulose (CMC)iyi-derivative ye-cellulose kanye nezinto zemvelo ze-polymer ezinezakhiwo ezinhle kakhulu njengokuncibilika kwamanzi, i-viscosity kanye nokuqina. Ngenxa yokuhambisana kwayo okuhle kwezinto eziphilayo, ukungabi nobuthi kanye nokubola, i-CMC isetshenziswa kabanzi ekudleni, emithini, kumakhemikhali ansuku zonke, ekwenzeni amaphepha, ezindwangu, ekukhishweni kwamafutha nakwezinye izimboni. Njengezinto ezibalulekile ezisebenzayo, izinga lekhwalithi le-CMC lidlala indima ebalulekile eqondisayo emikhakheni ehlukene.
1. Izakhiwo eziyisisekelo ze-CMC
Isakhiwo samakhemikhali se-AnxinCel®CMC ukwethula amaqembu e-carboxymethyl (-CH2COOH) kuma-molecule e-cellulose, ukuze ibe nokuncibilika kwamanzi okuhle. Izakhiwo zayo eziyinhloko zifaka:
Ukuncibilika kwamanzi: I-CMC ingakha isixazululo esibonakalayo esiqinile emanzini futhi isetshenziswa kabanzi njengesithambisi noma isiqinisi emikhiqizweni ehlukahlukene yoketshezi.
Ukuqina: I-CMC inobuthi obukhulu futhi ingakhuphula ngempumelelo ukuhambisana koketshezi futhi inciphise ukugeleza koketshezi.
Ukuzinza: I-CMC ibonisa ukuzinza okuhle kwamakhemikhali kumazinga ahlukene e-pH kanye nokushisa.
Ukubola kwe-biogradability: I-CMC iyi-derivative ye-cellulose yemvelo enokubola kwe-biogradability okuhle kanye nokusebenza okuhle kwemvelo.
2. Izindinganiso zekhwalithi ze-CMC
Izindinganiso zekhwalithi ze-CMC ziyahlukahluka ngokuya ngezinkambu ezahlukene zokusetshenziswa kanye nezidingo zokusebenza. Okulandelayo ezinye zezindinganiso eziyinhloko zekhwalithi:
Ukubukeka: I-CMC kufanele ibe impuphu noma ama-granule amhlophe noma amhlophe qwa. Akufanele kube khona ukungcola okubonakalayo kanye nezinto zangaphandle.
Okuqukethwe komswakama: Okuqukethwe komswakama kwe-CMC ngokuvamile akudluli u-10%. Umswakama owedlulele uzothinta ukuzinza kwesitoreji se-CMC kanye nokusebenza kwayo ekusetshenzisweni kwayo.
Ukujiya: Ukujiya kungenye yezinkomba ezibalulekile ze-CMC. Ngokuvamile kunqunywa ngokulinganisa ukujiya kwesisombululo sayo samanzi nge-viscometer. Uma ukujiya kuphakeme, kulapho umphumela wokujiya we-CMC uqina khona. Ukujiya okuhlukene kwezixazululo ze-CMC kunezidingo ezihlukile zokujiya, ngokuvamile phakathi kuka-100-1000 mPa·s.
Isilinganiso Sokushintsha (inani le-DS): Isilinganiso Sokushintsha (i-DS) singenye yezici ezibalulekile ze-CMC. Simelela inani elimaphakathi lokushintsha kwe-carboxymethyl kuyunithi ngayinye ye-glucose. Ngokuvamile, inani le-DS liyadingeka ukuthi libe phakathi kuka-0.6-1.2. Inani eliphansi kakhulu le-DS lizothinta ukuncibilika kwamanzi kanye nomphumela wokujiya kwe-CMC.
I-asidi noma inani le-pH: I-pH yesisombululo se-CMC ngokuvamile iyadingeka ibe phakathi kuka-6-8. I-pH ephansi kakhulu noma ephezulu kakhulu ingathinta ukuzinza kanye nomphumela wokusetshenziswa kwe-CMC.
Okuqukethwe komlotha: Okuqukethwe komlotha okuqukethwe yizinto ezingaphili ku-CMC, okuvame ukudingeka ukuthi kungadluli u-5%. Okuqukethwe komlotha okuphezulu kakhulu kungathinta ukuncibilika kwe-CMC kanye nekhwalithi yokusetshenziswa kokugcina.
Ukuncibilika: I-CMC kufanele incibilike ngokuphelele emanzini ekushiseni kwegumbi ukuze yakhe isixazululo esibonakalayo nesilengayo. I-CMC encibilika kabi ingase ibe nokungcola okungancibiliki noma i-cellulose esezingeni eliphansi.
Okuqukethwe kwensimbi esindayo: Okuqukethwe kwensimbi esindayo ku-AnxinCel®CMC kumele kuhambisane nezindinganiso zikazwelonke noma zemboni. Ngokuvamile kuyadingeka ukuthi okuqukethwe okuphelele kwensimbi esindayo kungadluli ku-0.002%.
Izinkomba ze-microbiological: I-CMC kufanele ihlangabezane nezindinganiso zomkhawulo wamagciwane. Kuye ngokusetshenziswa, i-CMC yezinga lokudla, i-CMC yezinga lemithi, njll. zidinga ukulawulwa okuqinile kokuqukethwe kwamagciwane ayingozi njengebhaktheriya, isikhunta, kanye ne-E. coli.
3. Izindinganiso zokusetshenziswa ze-CMC
Izinkambu ezahlukene zinezidingo ezahlukene ze-CMC, ngakho-ke kudingeka kuklanywe amazinga athile ohlelo lokusebenza. Izindinganiso ezivamile zohlelo lokusebenza zifaka:
Imboni yokudla: I-CMC esezingeni lokudla isetshenziselwa ukuqina, ukuzinza, ukuhlanganisa ukudla, njll., futhi iyadingeka ukuze ihlangabezane nezindinganiso zokuphepha kokudla, njengokungabuthi, okungenangozi, okungenazo izinto ezibangela ukungezwani komzimba, futhi inokuncibilika kwamanzi okuhle kanye nokunamathela kahle. I-CMC ingasetshenziswa futhi ukunciphisa okuqukethwe kwamafutha nokuthuthukisa ukunambitheka kanye nokuthungwa kokudla.
Imboni yezemithi: Njengesithako esivamile semithi, i-CMC yezinga lezemithi idinga ukulawulwa okuqinile kokungcola, okuqukethwe kwamagciwane, ukungabi nobuthi, ukungazweli komzimba, njll. Imisebenzi yayo eyinhloko ifaka phakathi ukukhishwa okulawulwayo kwemithi, ukuqina, izinamathiselo, njll.
Amakhemikhali ansuku zonke: Ezimonyweni, ezihlanzweni kanye nakwamanye amakhemikhali ansuku zonke, i-CMC isetshenziswa njengesithambisi, isiqinisi, i-ejenti yokumisa, njll., futhi iyadingeka ukuze ibe nokuncibilika kwamanzi okuhle, ukujiya kanye nokuqina.
Imboni yokwenza amaphepha: I-CMC isetshenziswa njenge-glue, i-ejenti yokumboza, njll. enqubweni yokwenza amaphepha, edinga i-viscosity ephezulu, ukuzinza kanye nezinga elithile lekhono lokulawula umswakama.
Ukusetshenziswa kwe-oyili: I-CMC isetshenziswa njengesithasiselo soketshezi oketshezini lokubhoboza i-oyili ukuze kwandiswe ukuthamba nokukhulisa ukuthamba. Ukusetshenziswa okunjalo kunezidingo eziphezulu zekhono le-CMC lokuncibilika nokukhulisa ukuthamba.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe,I-CMC, njengezinto zemvelo ze-polymer, izoqhubeka nokwandisa izindawo zayo zokusetshenziswa. Lapho kwakhiwa amazinga ekhwalithi yezinto ze-CMC, ngaphezu kokucabangela izakhiwo zayo zomzimba nezamakhemikhali, kuyadingeka futhi ukucabangela ngokuphelele izidingo zayo zokusetshenziswa ukuqinisekisa ukuthi ingahlangabezana nezidingo zemikhakha ehlukene yezimboni. Ukwakha amazinga anemininingwane futhi acacile kuyindlela ebalulekile yokuqinisekisa ikhwalithi kanye nomphumela wokusetshenziswa kwemikhiqizo ye-AnxinCel®CMC, futhi kuyisihluthulelo sokuthuthukisa ukuncintisana kwemakethe kwezinto ze-CMC.
