Uhlalutyo lokusasaza kwe-carboxymethyl seluplose (cmc)

I-Carboxymethyl Selelose (CMC) yi-Polymer esetyenziswe ngamanzi amaninzi ngokudityaniswa kakuhle nokungazinzanga okuhle, ukuqina kunye nokuzinza kwecolloidal. Ifunyanwa ngokutshintsha amaqela e-hydroxyl kwi-selsulose molecular thein kunye ne-carboxymethyl amaqela (-C2cooh). Olu hlengahlengiso lwekhemikhali lwenza imolekyuli ye-CMC inobuqhetseba obunamandla kunye nokusasazeka okulungileyo, ngakumbi kwisisombululo esibalulekileyo, kusetyenziswa i-viscotity yobuchule obubalulekileyo, ngenxa yoko isetyenziswa ngokubanzi kumzi-mveliso, ukutya, amayeza, amayeza, amayeza, amayeza, cosmetics kunye namanye amasimi.

1. Inkcazo kunye nokuphembelela izinto zokusasazwa kwe-CMC
Ukusasazeka kwe-CMC kudla ngokubhekisa kubuchule bayo bokusasazeka kunye nokunyibilika emanzini okanye ezinye izinto. I-SellUlose uqobo ingena emanzini, kodwa emva kokulungiswa, i-CMC inesifo esihle samanzi. Ukwahlulwa kwayo kuyachaphazeleka ngezinto ezininzi, ikakhulu kubandakanya le miba ilandelayo:

Ubunzima bemolekyuli: ubunzima bemolekyuli ye-CMC ichaphazela ngokuthe ngqo ukulimala kwayo kunye nokusasazeka kwayo. Ubunzima obuphezulu bemolekyuli buhlala buthetha isakhiwo esikhulu semolekyuli, esinokuthi sikhokelele ekuchitheni kancinci kwaye sinokuchaphazela ukufika kwesisombululo sokugqibela, ngaloo ndlela echaphazela isiphumo sokusasazwa. I-CMC enomthwalo wemolekyuli ophantsi inobunzima obungcono kwisisombululo, kodwa isiphumo sayo esinxunguphalisayo sibe buthathaka.

Inqanaba lebhokisi ye-carboxymethy Inqanaba eliphezulu lebhokisi yebhokisi ye-carboxymmethyth lithetha amaqela ama-hydrophilic (-Cooo) kwimolekyuli, enokwenza i-hydrogen ye-hydrogen kunye nokomeleza intsebenzo phakathi kweemolekyuli, ngaloo ndlela ukuphucula i-smobiobility kunye nokusasazeka kwe-CMC. Ngokuchasene noko, inqanaba elincinci lebhokisi yebhokisi ye-carboxymethyyting inokukhokelela ekusasazeni kakubi kwe-CMC, okanye nokuba nobunzima bokunyibilikisa.

Ixabiso le-PH yesisombululo: Ukuzalwa nokusasazeka kunye nokusasazeka kwe-CMC kungahluka kakhulu kwiinqobo ezahlukeneyo zexabiso. Kwimeko ye-acidic okanye ukungathathi cala, i-CMC ngokubanzi ingonakali; Ngelixa ngaphantsi kwemeko ye-alkaline, i-CYC's Hydrophility iphuculwe, enokunyusa i-viscofity yesisombululo se-CMC kwaye ichaphazele ukusasazeka kwayo. Ke ngoko, uhlengahlengiso lwexabiso le-pH lubalulekile ekusasazeni i-CMC.

Amandla e-Ionic: Ukugxininiswa kwe-ion kwisisombululo kuya kuchaphazela ukusasazeka kwe-CMC. Ugxininiso oluphezulu lweetyiwa okanye ezinye izinto ze-iones zinokunciphisa isothulolo kunye nokusasazeka kwawo ngokunxibelelana nezityholo ezimbi kwiimolekyuli ze-CMC. I-CMC ibonisa ukusasazeka kwempembelelo entle phantsi kwamandla ase-Ionic esezantsi.

Iqondo lokushisa: Iqondo lobushushu linefuthe elithile ekusasazeni i-CMC. Ngokubanzi, ukwanda kwamaqondo obushushu kuya kukhawulezisa inkqubo yokupheliswa kwe-CMC kunye nokuphucula ukusasazeka. Nangona kunjalo, iqondo eliphakamileyo kakhulu linokubangela ukuqhekezwa okanye ukudityaniswa kwe-CMC ye-CMC Molecular, ethi ichaphazele isiphumo sokuzinza kunye nokusasazeka kwazo. Ke ngoko, ulawulo olululo lobushushu lubalulekile ekusasazeni i-CMC.

I-2. Iindawo zokufunda ze-CMC
Ukuhlaselwa okugqwesileyo kwe-CMC kwenza ukuba isetyenziswe ngokubanzi kwiindawo ezininzi. Oku kulandelayo zezinye zeendawo eziphambili:

I-Coasthis kunye nepeyinti: Kwinkqubo yokulungiselela iingubo kunye neepeyinti, i-CMC, njenge-gickener kwaye isasazeke ngokufanelekileyo kwaye iwathintela amasuntswana kwaye athintele ekusombululeni. Ngenxa ye-hydrophicity eyomeleleyo, i-CMC inokudlala izenzo ezigwenxa ezigqwesileyo, ngaloo ndlela ziphucula uzinzo kunye nokufana kokudibana.

Umzi-mveliso wokutya: i-CMC, njengendawo enkulu kwaye isetyenziswa kwindawo yokutya, efana ne-jelly, i-ice cream, ishey. Ukutya, i-CMC inceda ekuphuculeni ukuthungwa kunye nokuncamathela imveliso, ngelixa uqinisekisa ukuxutywa kwezinto ezingafakwanga ngokuphucula ukusasazeka.

Amalungiselelo amachiza amayeza: Kumzi-mveliso wamayeza, i-CMC isetyenziswa njengokusasazeka kunye nokuzinzisa kumalungiselelo amachiza amachiza, i-geses yezamayeza, iliso lamehlo, ukunqunyanyiswa kwamanye amalungiselelo. Ukungahambi kakuhle kuyanceda ekuqinisekiseni ukusasazwa ngokufanayo kwezithako zamachiza kunye nokuphucula uzinzo lokusebenza kweziyobisi.

Ishishini le-Cosmetic: I-CMC isetyenziswa ngokubanzi kwi-cosmetics, ngakumbi kwiimveliso ezinjengeedokom, iikhrim, i-shampoos kunye ne-jells yeshawari. Ukusasazeka kwayo kunokuqinisekisa ukusasazwa kwe-iyunifomu yezithako kunye nokuphucula uzinzo kunye nokusebenzisa amava eemveliso.

Iphepha kunye neeleyibhile: I-CMC ihlala isetyenziswa kwinkqubo yokwenziwa kwemveliso kunye nee-ticts njenge-thi chupokener kunye nokusasazeka ukuphucula amandla kunye nomgangatho wephepha. Kwinkqubo yokuprinta kunye nokudaya kwe-DEY YORK, i-CMC inokusasaza i-dys kunye ne-pigment ukuqinisekisa ukuba i-dilomung ye-dilom.

I-3. Isicwangciso sokuziqhelanisa nokusasazeka kwe-CMC
Ukuze ukwazi ukuphucula ukusasazeka kwe-CMC, ezi zicwangciso zoncedo zilandelayo ziya kwamkelwa:

Lungisa ubunzima bemolekyuli kunye ne-carboxymethythy ye-CMC: ngokulawula ubunzima bemolekyuli kunye nebhokisi ye-carboxymethythy ye-CMC, ukusasazeka kwayo kwizicelo ezahlukeneyo kunokuhlengahlengiswa. Umzekelo, ubunzima obuphezulu bemolekyuli kunye nenqanaba eliphezulu lebhokisi yebhokisi ye-carboxymethyyting inokunceda ukuphucula ukusasazeka kwe-CMC kwisisombululo esinamandla.

Ukusetyenziswa kwe-surfacants: kwezinye iinkqubo, ukongeza isixa esifanelekileyo se-surfacants kunokuphucula ukusasazeka kwe-CMC, ngakumbi xa ujongene nezinto ezingafunekiyo zeoyile. I-surfacapes inokunciphisa uxinzelelo kunye nokukhuthaza ukusasazeka kweemolekyuli ze-CMC.

Ukuphelisa iimeko zokugqaliselwa: Ukulawulwa ngokufanelekileyo kweqondo lobushushu le-CMC, ixabiso le-pH kunye nokugxininiswa kweSolvent kunokuphucula ukusasazeka kwawo. Umzekelo, i-CMC ngokubanzi ilunge ngakumbi kwiqondo lokushisa eliphantsi kunye neemeko ze-PH.

Ukudibanisa abanye abasasazi: kwizicelo ezithile ezikhethekileyo, i-CMC inokudityaniswa nabanye abasasazi ukufezekisa izenzo ezingcono. Umzekelo, ezinye iipoli zemolekyuli eziphakamileyo zemolekyuli okanye iimveliso zendalo zinokusebenza nge-CMC ukuphucula ukusasazeka kwayo.

I-Carboxymethyl Selelose ineentsali ezigqwesileyo kwaye isetyenziswa ngokubanzi kwi-cayishini, ukutya, amayeza, amayeza kunye namanye amashishini. Ukusasazeka kwayo kuchaphazeleke zizinto ezininzi ezinje ngomonde wemolekyuli, isidanga sebhokisi yebhokisi ye-carboxymethy Ukusasazeka kwe-CMC kunokuphuculwa ngakumbi ngeendlela ezifanelekileyo zokwenza izinto, ezinjengokuhlengahlengisa ubunzima bemolekyuli kunye nokusebenzisa i-surfacants. Njengoko imfuno yemizi-mveliso iyaqhubeka nokwanda, uphando lwe-CMC luka-CMC luya kuqhubeka nokwenza nzulu ukuhlangabezana neemfuno ezahlukeneyo zamacandelo ahlukeneyo.
