I-Carboxymethyl Cellulose (CMC)iyinhlanganisela ye-polymer encibilika emanzini eyakhiwe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Isetshenziswa kabanzi emikhiqizweni yamakhemikhali yansuku zonke. Njenge-thickener evamile, i-stabilizer kanye ne-ejenti yokumisa, i-CMC ithatha isikhundla esibalulekile emikhiqizweni yansuku zonke yamakhemikhali njengemikhiqizo yokunakekelwa kwesikhumba, umuthi wokuxubha, okokuhlanza, njll. ngezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali.
1. Amakhemikhali e-carboxymethyl cellulose
I-CMC ikhiqizwa ukusabela kwe-cellulose yemvelo ne-sodium chloroacetate (noma i-chloroacetic acid) endaweni ene-alkali. Isakhiwo sayo samangqamuzana ikakhulukazi sihlanganisa i-cellulose skeleton kanye namaqembu amaningi e-carboxymethyl (-CH₂-COOH), futhi ukwethulwa kwala maqembu kunikeza i-CMC hydrophilicity. Isisindo samangqamuzana kanye nezinga lokushintshwa kwe-CMC (okungukuthi, izinga lokushintshwa kwe-carboxymethyl ku-molecule ye-cellulose) amapharamitha abalulekile athinta ukunyibilika kanye nomthelela wokujiya. Ekwakhiweni kwemikhiqizo yamakhemikhali yansuku zonke, i-CMC ngokuvamile ivela njengempushana emhlophe noma ephuzi kancane enokuncibilika okuhle kwamanzi kanye nezakhiwo ezijiya.
2. Izici ezisebenzayo ze-carboxymethyl cellulose
Izakhiwo ze-physicochemical ye-CMC ziyinikeza imisebenzi eminingi emikhiqizweni yansuku zonke yamakhemikhali:
Ukusebenza okuqinisayo: I-CMC ikhombisa umphumela wokujiya esixazululweni esinamanzi, futhi i-viscosity yesisombululo ingalungiswa ngokugxila, isisindo samangqamuzana kanye nezinga lokushintshwa kwe-CMC. Ukwengeza i-CMC emikhiqizweni yamakhemikhali yansuku zonke ngenani elifanele kungakhuphula i-viscosity yomkhiqizo, kulethe umuzwa ongcono womsebenzisi, futhi kuvimbele umkhiqizo ekuhlungeni noma ekulahlekeni.
I-Stabilizer ne-ejenti yokumisa: Iqembu le-carboxyl esakhiweni samangqamuzana e-CMC lingakha amabhondi e-hydrogen ngama-molecule amanzi futhi libe nokuncibilika okuhle kwamanzi nokunamathela. I-CMC ingakha uhlelo lokumiswa olusatshalaliswe ngendlela efanayo esixazululweni, ngaleyo ndlela isize ukuzinzisa izinhlayiya ezingancibiliki noma amaconsi kawoyela emkhiqizweni futhi ivimbele imvula noma ukuhlukaniswa. Lesi sakhiwo sibaluleke kakhulu ezintweni zokuhlanza kanye nemikhiqizo yokunakekelwa kwesikhumba e-emulsified equkethe i-particle.
Isakhiwo sokwenza ifilimu: I-CMC inendawo enhle kakhulu yokwenza ifilimu, eyenza ifilimu evikelayo ebusweni besikhumba noma amazinyo, enganciphisa ukuhwamuka kwamanzi futhi ikhulise umphumela wokuthambisa womkhiqizo. Lesi sakhiwo sisetshenziswa kakhulu emikhiqizweni yokunakekelwa kwesikhumba kanye nemikhiqizo yokunakekelwa komlomo.
Ukuthambisa: Emikhiqizweni yansuku zonke yamakhemikhali efana nokuxubha amazinyo kanye negwebu lokushefa, i-CMC inganikeza ukuthambisa okuhle, isize ukuthuthukisa ukushelela komkhiqizo, inciphise ukungqubuzana, futhi ngaleyo ndlela ithuthukise ulwazi lomsebenzisi.
3. Ukusetshenziswa kwe-carboxymethyl cellulose emikhiqizweni yansuku zonke yamakhemikhali
Izakhiwo ezihlukahlukene ze-CMC ziyenza ibe isithako esibalulekile emikhiqizweni yansuku zonke yamakhemikhali. Okulandelayo ukusetshenziswa kwayo okukhethekile emikhiqizweni ehlukene:
3.1 Inhlama yamazinyo
Umuthi wokuxubha uyisibonelo esijwayelekile sokusetshenziswa kwe-CMC emikhiqizweni yansuku zonke yamakhemikhali. I-CMC isetshenziswa kakhulu njenge-thickener kanye ne-stabilizer ku-toothpaste. Njengoba umuthi wokuxubha udinga i-viscosity ethile ukuze kuqinisekiswe ukuhlanza okuphumelelayo nokunethezeka lapho uxubha amazinyo, ukungezwa kwe-CMC kungandisa i-viscosity ye-toothpaste, ukuze kungabi mncane kakhulu ukunamathela ku-toothbrush, noma kukhulu kakhulu ukuze kuthinte i-extrusion. I-CMC ingasiza futhi ukumisa ezinye izithako ezingancibiliki njengama-abrasives ku-toothpaste ukugcina ukuthungwa komuthi wokuxubha kuzinzile. Ngaphezu kwalokho, ifilimu eyenza ifilimu ye-CMC ikwazi ukwenza ungqimba oluvikelayo ebusweni bamazinyo, okwandisa umphumela wokuhlanza womlomo womlomo.
3.2 Izihlanzi
Iqhaza le-CMC ezintweni zokuhlanza libaluleke ngokufanayo. Izihlanzi eziningi eziwuketshezi kanye noketshezi lokugeza izitsha ziqukethe izinhlayiya ezingancibiliki kanye nama-surfactants, athambekele ekuhlukaniseni ngesikhathi sokugcinwa. I-CMC, njenge-ejenti elengayo kanye ne-thickener, ingamisa izinhlayiya ngempumelelo, iqinise ukuthungwa komkhiqizo, futhi igweme ukuhlukaniswa. Ngaphezu kwalokho, i-CMC inganikeza ukugcotshwa okuthile ngesikhathi sokusetshenziswa futhi inciphise ukucasuka kwesikhumba, ikakhulukazi kumshini wokuhlanza izingubo nensipho yezandla.
3.3 Imikhiqizo yokunakekelwa kwesikhumba
Emikhiqizweni yokunakekelwa kwesikhumba, i-CMC isetshenziswa kabanzi njenge-thickener kanye ne-moisturizer. Isibonelo, emikhiqizweni enjengamafutha okugcoba, ama-creams kanye ne-essences, i-CMC ingakhuphula ngempumelelo i-viscosity yomkhiqizo futhi ilethe umuzwa obushelelezi wokusetshenziswa. Izakhiwo ze-CMC ezenza ifilimu zikwazi ukwenza ifilimu evikelayo ebusweni besikhumba ukuze kuvinjelwe ukuhwamuka kwamanzi nokwandisa umphumela wokuthambisa womkhiqizo, ngaleyo ndlela kufezeke inhloso yokuthambisa isikhathi eside. Ngaphezu kwalokho, i-CMC inokuphepha okuphezulu futhi ifanele isikhumba esibucayi nezinhlobo ezahlukene zesikhumba.
3.4 Ukushefa amagwebu nemikhiqizo yokugeza
Kumikhiqizo yokushefa igwebu neyokugeza,I-CMCingadlala indima yokugcoba, ithuthukise ukushelela komkhiqizo, futhi inciphise ukungqubuzana kwesikhumba. Umthelela wokujiya we-CMC ungaphinda uthuthukise ukuzinza kwegwebu, wenze igwebu libe ntekenteke futhi lihlale njalo, ilethe umuzwa ongcono wokushefa nokugeza. Ukwengeza, impahla yokwenza ifilimu ye-CMC ingakha isendlalelo sokuzivikela esikhumbeni, sinciphise ukucasuka kwangaphandle, ikakhulukazi efanelekayo isikhumba esibucayi.
4. Ukuphepha nokusimama kwe-carboxymethyl cellulose
I-CMC isuselwa ku-cellulose yemvelo futhi inokubola okuphezulu kwe-biodegradability. Ngeke kubangele ukungcola okuqhubekayo emvelweni ngesikhathi sokusetshenziswa, okuhlangabezana nezidingo zentuthuko esimeme. I-CMC iphinde yafakazelwa ukuthi iphephile uma kuqhathaniswa nokusetshenziswa abantu. I-CMC igunyazwe njengesengezo sokudla emazweni amaningi, okubonisa ukuthi inobuthi obuphansi emzimbeni womuntu. Okuqukethwe kwe-CMC emikhiqizweni yamakhemikhali yansuku zonke ngokuvamile kuphansi. Ngemuva kokuhlolwa okuningi komtholampilo, i-CMC ngeke ibangele ukucasuka okukhulu esikhumbeni noma emlonyeni womlomo, ngakho ilungele zonke izinhlobo zabantu.
Ukusetshenziswa okubanzi kwei-carboxymethyl cellulose (CMC)emikhiqizweni yamakhemikhali yansuku zonke ifakazela ukusebenza kwayo okuhle kakhulu nokuguquguquka. Njenge-thickener ephephile, esebenza kahle futhi esimeme, i-ejenti yokumisa kanye ne-lubricant, i-CMC idlala indima ebalulekile emikhiqizweni ehlukahlukene yansuku zonke yamakhemikhali njengemikhiqizo yokunakekelwa kwesikhumba, umuthi wokuxubha, okokuhlanza, njll. Ayikwazi nje ukuthuthukisa isipiliyoni somkhiqizo, kodwa futhi ithuthukise. ukuzinza kanye nomphumela womkhiqizo. Ngaphezu kwalokho, ubungane bemvelo be-CMC kanye nokuwohloka kwemvelo kuyenza ihlangabezane nesidingo somphakathi wesimanje sezinto ezingavuthiwe ezihambisana nemvelo. Ngakho-ke, njengoba isidingo sabathengi semikhiqizo yekhwalithi ephezulu, ephephile, nehambisana nemvelo sikhula, amathuba okusebenza kwe-CMC embonini yamakhemikhali yansuku zonke azoba banzi.
