I-Carboxymethyl Cellulose (CMC)yikhompawundi yepolymer enyibilikayo emanzini eyenziwe ngokuguqulwa kweekhemikhali zeselulosi yendalo. Isetyenziswa ngokubanzi kwiimveliso zemichiza yemihla ngemihla. Njenge-thickener eqhelekileyo, i-stabilizer kunye ne-arhente yokumisa, i-CMC ikwindawo ebalulekileyo kwiimveliso zemichiza yemihla ngemihla njengemveliso yokunakekelwa kwesikhumba, i-toothpaste, i-detergents, njl. kunye neempawu zayo ezibalaseleyo zomzimba kunye neekhemikhali.
1. Iimpawu zeMichiza ye-carboxymethyl cellulose
I-CMC iveliswa kukusabela kwe-cellulose yendalo kunye ne-sodium chloroacetate (okanye i-chloroacetic acid) kwindawo yealkaline. Isakhiwo sayo se-molecular ikakhulu sibandakanya i-cellulose skeleton kunye namaqela amaninzi e-carboxymethyl (-CH₂-COOH), kwaye ukuqaliswa kwala maqela kunika i-CMC i-hydrophilicity. Ubunzima bemolekyuli kunye neqondo lokutshintshwa kwe-CMC (oko kukuthi, ireyithi ye-carboxymethyl endaweni ye-cellulose molekyuli) ziiparamitha eziphambili ezichaphazela ukunyibilika kwayo kunye nesiphumo sokujiya. Ekuqulunqweni kweemveliso zemichiza yemihla ngemihla, i-CMC idla ngokubonakala njengomgubo omhlophe okanye otyheli kancinane kunye nokunyibilika kakuhle kwamanzi kunye neempawu zokujiya.
2. Iimpawu ezisebenzayo ze-carboxymethyl cellulose
Iipropathi ze-physicochemical ze-CMC zinika imisebenzi emininzi kwiimveliso zemichiza yemihla ngemihla:
Ukuqina kokusebenza: I-CMC ibonisa isiphumo sokuqina kwisisombululo esimanzi, kunye ne-viscosity yesisombululo sayo sinokuhlengahlengiswa kunye noxinaniso, ubunzima bemolekyuli kunye nenqanaba lokuthatha indawo ye-CMC. Ukongeza i-CMC kwiimveliso zemichiza yemihla ngemihla kwisixa esifanelekileyo kunokunyusa i-viscosity yemveliso, kuzise amava angcono omsebenzisi, kwaye kuthintele imveliso kwi-stratification okanye ilahleko.
I-Stabilizer kunye ne-arhente yokumisa: Iqela le-carboxyl kwisakhiwo se-molecular ye-CMC linokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi kwaye zinokunyibilika kakuhle kwamanzi kunye nokunamathela. I-CMC inokwenza inkqubo yokunqunyanyiswa esasazwe ngokufanayo kwisisombululo, ngaloo ndlela inceda ukuzinzisa amasuntswana anganyibilikiyo okanye amathontsi e-oyile kwimveliso kunye nokuthintela imvula okanye i-stratification. Le propati ibaluleke kakhulu kwiimveliso zokucoca kunye ne-emulsified skin care products eziqulethe i-particle.
Ipropathi yokwenza ifilimu: I-CMC inepropathi egqwesileyo yokwenza ifilimu, eyenza ifilimu ekhuselayo phezu kwesikhumba okanye amazinyo, enokunciphisa ukuphuphuma kwamanzi kunye nokwandisa umphumo wokufuma kwimveliso. Le propati isetyenziswa ngokubanzi kwiimveliso zokunakekelwa kwesikhumba kunye neemveliso zokunakekelwa ngomlomo.
Ukuthambisa: Kwiimveliso zemichiza yemihla ngemihla ezifana nentlama yamazinyo kunye negwebu lokucheba, i-CMC inokubonelela ngokuthambisa okulungileyo, incede ekuphuculeni ukuguda kwemveliso, inciphise ukungqubana, kwaye ngaloo ndlela iphucule amava omsebenzisi.
3. Ukusetyenziswa kwe-carboxymethyl cellulose kwiimveliso zemichiza yemihla ngemihla
Iipropati ezahlukeneyo ze-CMC zenza ukuba ibe yinto ebalulekileyo kwiimveliso zemichiza yemihla ngemihla. Oku kulandelayo kukusetyenziswa kwayo kwiimveliso ezahlukeneyo:
3.1 Intlama yamazinyo
Intlama yamazinyo ngumzekelo oqhelekileyo wesicelo seCMC kwiimveliso zemichiza yemihla ngemihla. I-CMC isetyenziswa ikakhulu njengento etyebisayo kunye nezinzisi kwintlama yamazinyo. Ekubeni intlama yamazinyo idinga i-viscosity ethile yokuqinisekisa ukucocwa okusebenzayo kunye nokuthuthuzela xa kuxutyushwa amazinyo, ukongezwa kwe-CMC kunokunyusa i-viscosity ye-toothpaste, ukuze ingabi yincinci kakhulu ukuba ibambelele kwibrashi yamazinyo, okanye iqine kakhulu ukuba ichaphazele i-extrusion. I-CMC inokunceda nokumisa ezinye izithako ezinganyibilikiyo ezifana neziqholo kwintlama yamazinyo ukugcina ukuthungwa kwentlama yamazinyo kuzinzile. Ukongezelela, ipropati yokwenza ifilimu ye-CMC yenza ukuba yenze uluhlu olukhuselayo phezu kwamazinyo, ukwandisa umphumo wokucoca umlomo womlomo.
3.2 Izicoci
Indima ye-CMC kwizicoci ibaluleke ngokulinganayo. Uninzi lwezicoci zolwelo kunye nolwelo lokuhlamba izitya luqulathe amasuntswana anganyibilikiyo kunye ne-surfactants, athanda ukuhluzwa ngexesha lokugcinwa. I-CMC, njenge-agent exhomayo kunye ne-thickener, inokumisa ngokufanelekileyo amasuntswana, izinzile ukuthungwa kwemveliso, kwaye iphephe ukucwangciswa. Ukongeza, i-CMC inokubonelela ngokuthambisa okuthile ngexesha lokusetyenziswa kunye nokunciphisa ukucaphuka kwesikhumba, ngakumbi kwisicoci sempahla kunye nesepha yesandla.
3.3 Iimveliso zokhathalelo lolusu
Kwiimveliso zokhathalelo lwesikhumba, i-CMC isetyenziswa ngokubanzi njenge-thickener kunye ne-moisturizer. Ngokomzekelo, kwiimveliso ezifana ne-lotions, i-creams kunye ne-essences, i-CMC inokunyusa ngokufanelekileyo i-viscosity yemveliso kwaye izise imvakalelo egudileyo yokusetyenziswa. Iimpawu zokwenza ifilimu ye-CMC yenza ukuba yenze ifilimu ekhuselayo kwindawo yesikhumba ukuthintela ukukhuphuka kwamanzi kunye nokwandisa umphumo wokunyusa wemveliso, ngaloo ndlela ufezekise injongo yokunyusa ixesha elide. Ukongeza, i-CMC inokhuseleko oluphezulu kwaye ilungele ulusu olubuthathaka kunye neentlobo ezahlukeneyo zolusu.
3.4 Ukucheba amagwebu kunye neemveliso zokuhlambela
Ekuchebeni amagwebu kunye neemveliso zokuhlambela,CMCinokudlala indima yokuthambisa, iphucule ukuguda kwemveliso, kwaye inciphise ukukhuhlana kolusu. Isiphumo sokutyeba se-CMC sinokomeleza uzinzo lwegwebu, lwenza ugwebu lube-ethe-ethe kwaye luhlale luhleli, luzisa ukucheba ngcono kunye namava okuhlamba. Ukongezelela, ipropati yokwenza ifilimu ye-CMC inokwenza uluhlu olukhuselayo kwesikhumba, ukunciphisa ukucaphuka kwangaphandle, ngokukodwa ukulungeleka kwesikhumba esibucayi.
4. Ukhuseleko kunye nokuzinza kwe-carboxymethyl cellulose
I-CMC ithathwe kwi-cellulose yendalo kwaye inokonakala okuphezulu kwe-biodegradability. Ayisayi kubangela ungcoliseko oluqhubekayo kwimo engqongileyo ngexesha lokusetyenziswa, oluhlangabezana neemfuno zophuhliso oluzinzileyo. I-CMC nayo ibonakaliswe ukuba ikhuselekile ngokwentelekiso kusetyenziso lwabantu. I-CMC ivunyiwe njengesongezo sokutya kumazwe amaninzi, ebonisa ukuba inetyhefu ephantsi emzimbeni womntu. Umxholo we-CMC kwiimveliso zemichiza yemihla ngemihla udla ngokuba phantsi. Emva kwezilingo ezininzi zeklinikhi, i-CMC ayizukubangela ukucaphuka okukhulu eluswini okanye kumgodi womlomo, ngoko ke ilungele zonke iintlobo zabantu.
Usetyenziso olubanzi lwei-carboxymethyl cellulose (CMC)kwiimveliso zemichiza yemihla ngemihla ingqina ukusebenza kwayo okugqwesileyo kunye nokuguquguquka. Njenge-thickener ekhuselekileyo, esebenzayo kwaye ezinzileyo, i-arhente yokumisa kunye ne-lubricant, i-CMC idlala indima ebalulekileyo kwiimveliso zeekhemikhali zemihla ngemihla ezifana nemveliso yokunakekelwa kwesikhumba, i-toothpaste, i-detergents, njl. ukuzinza kunye nesiphumo semveliso. Ukongeza, ubuhlobo bendalo be-CMC kunye nokonakaliswa kwezinto eziphilayo kuyenza ihlangabezane nemfuno yoluntu yangoku yemathiriyeli ekrwada yokusingqongileyo. Ke ngoko, njengoko imfuno yabathengi yomgangatho ophezulu, ekhuselekileyo, kunye nemveliso ehambelana nokusingqongileyo isanda, amathuba okusetyenziswa kwe-CMC kushishino lwemichiza yemihla ngemihla aya kuba banzi.
