Yikuphi ukungahambi kahle kwe-carboxymethyl cellulose?

I-Carboxymethyl Cellulose (CMC) iyinto esetshenziswayo ye-polymer esetshenziswa kabanzi ekudleni, emikhakheni, izimonyo, izimbotshana, izindwangu, izindwangu kanye nezinye izimboni. Izinzuzo zayo eziphambili zifaka phakathi ukuqina, ukuzinza, ukumiswa, ukumiswa, ukugcinwa kwamanzi neminye imisebenzi, ngakho-ke kusetshenziswa kabanzi emikhakheni eminingi. Kodwa-ke, naphezu kokusebenza kwayo okuhle kakhulu kuzicelo eziningi, i-CMC nayo inobunzima nemikhawulo, engakhawulela ukusetshenziswa kwayo ezindaweni ezithile noma idinga izindlela ezithile zokunqoba lezi zinto ezinzima.

1. I-solubity elinganiselwe

I-solubity ye-CMC emanzini iyisici esibalulekile, kepha ngaphansi kwezimo ezithile, i-solubity ingahle ikhawulelwe. Isibonelo, i-CMC ine-soubity empofu ezindaweni ezinosawoti noma emanzini aphezulu. Endaweni enosawoti onosawoti, ukukhishwa kwe-electrostatic phakathi kwamaketanga ama-molekcis ancishisiwe, okuholela ekusetshenzisweni okuningana kwe-intermolecular, okuthinta i-solubity yayo. Lokhu kubonakala ikakhulukazi lapho kufakwa emanzini olwandle noma emanzini aqukethe inani elikhulu lamaminerali. Ngaphezu kwalokho, i-CMC ihlakaze kancane emanzini okushisa okushisa futhi kungathatha isikhathi eside ukuncibilikisa ngokuphelele, okungaholela ekunciphiseni kahle ekukhiqizeni kwezimboni.

2. Ukuqina kwe-viscosity

I-viscosity ye-CMC ingahle ithintwe yi-PH, lokushisa, kanye namandla ionic ngesikhathi sokusetshenziswa. Ngaphansi kwezimo ze-acidic noma ze-alkali, i-viscosity ye-CMC ingancipha kakhulu, ithinta umphumela wayo wokuqina. Lokhu kungahle kube nomphumela omubi kwezinye izinhlelo zokusebenza ezidinga ukubonakala okuzinzile, njengokucubungula kokudla kanye nokulungiselela okwenziwe ngemithi. Ngaphezu kwalokho, ngaphansi kwezimo zokushisa eziphakeme, ukubonakala kwe-CMC kungahle kwehlise ngokushesha, okuholela ekusebenzeni okulinganiselwe kwezinye izinhlelo zokushisa okuphezulu.

3. I-biodegradadamating

I-CMC i-cellulose eguquliwe enesilinganiso sokuwohloka kancane, ikakhulukazi ezindaweni zemvelo. Ngakho-ke, i-CMC ine-biodegracative empofu futhi ingahle ibe umthwalo emvelo emvelweni. Yize i-CMC ingcono e-biodegradation kunama-polymers athile okwenziwa, inqubo yawo yokucekelwa phansi isathatha isikhathi eside. Kwezinye izinhlelo zokusebenza ezibucayi ngemvelo, lokhu kungaba ukucatshangelwa okubalulekile, okwenza abantu bafune ezinye izinto ezingesinye sezinto ezingesinye sezinto ezingesinye semvelo.

4. Izinkinga zokuqina kwamakhemikhali

I-CMC ingahle ingazinzile ezindaweni ezithile zamakhemikhali, njenge-acid enamandla, isisekelo esinamandla noma izimo ze-oxidative. Ukungcola noma ukusabela kwamakhemikhali kungenzeka. Lokhu kungazinzi kunganciphisa ukusetshenziswa kwayo ezindaweni ezithile zamakhemikhali. Emvelweni we-oxidizing emgodini, i-CMC ingahle ihlanganiswe nokuwohloka kwe-oxidative, ngaleyo ndlela ilahlekelwe ukusebenza kwayo. Ngaphezu kwalokho, kwezinye izixazululo eziqukethe i-metal ion, i-CMC ingahle ihlanganise ngensimbi yensimbi, okuthinta ukuqina kwayo nokuqina kwayo.

5. Intengo ephakeme

Yize i-CMC iyisitatimende esisebenza kahle kakhulu, izindleko zayo zokukhiqiza ziphakeme kakhulu, ikakhulukazi imikhiqizo ye-CMC ehlanzekile noma imisebenzi ethile. Ngakho-ke, kwezinye izinhlelo zokusebenza ezibucayi ezingabizi, ukusetshenziswa kwe-CMC kungenzeka kungabi ngokomnotho. Lokhu kungashukumisa izinkampani ukuthi zibheke ezinye izindlela ezingezelelwe ezibiza kakhulu lapho zikhetha abakhuthele noma abaqinisi, yize lezi zinye izindlela zingahle zibe zinhle njenge-CMC ekusebenzeni.

6. Kungahle kube nemikhiqizo eyenziwe ngenqubo yokukhiqiza

Inqubo yokukhiqiza ye-CMC ifaka ukuguqulwa kwamakhemikhali kwe-cellulose, okungakhiqiza eminye imikhiqizo, njenge-sodium chloride, i-sodium carboxylic acid, njll. Le mikhiqizo ye-carboxylic, yethula ukungcola okungathandeki ngaphansi kwezimo ezithile. Ngaphezu kwalokho, ama-reagents wamakhemikhali asetshenziswa kwinqubo yokukhiqiza angaba nomthelela omubi emvelweni uma engaphathwa kahle. Ngakho-ke, yize i-CMC ngokwayo inezakhiwo eziningi ezinhle kakhulu, imiphumela yezemvelo nezempilo yenqubo yayo yokukhiqiza nayo iyisici esidinga ukucatshangelwa.

7. Ukuthambekela okukhawulelwe

Yize i-CMC isetshenziswa kabanzi kwezokwelapha kanye nezimonyo futhi ine-biocomtic enhle, ukuqina kwawo kungase kungenele ezinye izinhlelo. Isibonelo, kwezinye izimo, i-CMC ingadala ukucasuka kwesikhumba noma ukusabela komzimba, ikakhulukazi lapho isetshenziswa ekugxilweni okuphezulu noma isikhathi eside. Ngaphezu kwalokho, i-metabolism nokuqedwa kwe-CMC emzimbeni kungathatha isikhathi eside, okungenzeka kungabi kahle ezinhlelweni ezithile zokulethwa kwezidakamizwa.

8. Izakhiwo ezingenamishini ezinganele

Njengomkhulu kanye ne-stabilizer, i-CMC inamandla aphansi emishini, okungenzeka ukuthi yinto ekhawulelwe kwezinye izinto ezidinga amandla aphezulu noma ukuqina okuphezulu. Isibonelo, kwezinye izindwangu noma izinto ezihlanganisiwe ezinezidingo zamandla aphezulu, ukusetshenziswa kwe-CMC kungahle kunqunyelwe noma kungadinga ukusetshenziselwa ukuhlanganiswa nezinye izinto zokuthuthukisa izakhiwo zayo zemishini.

Njengokusebenza okusebenzayo okusetshenziswayo okubanzi, i-carboxymethyllls (CMC) inezinzuzo eziningi, kepha ukunganaki kwayo nokulinganiselwa akunakwa. Lapho usebenzisa i-CMC, izici ezinjengokuzinikela kwayo, ukuzinza kwento, ukuqina kwamakhemikhali, umthelela wezemvelo nezindleko kumele kubhekwe ngokucophelela ngokuya ngesimo esithile sohlelo lokusebenza. Ngaphezu kwalokho, ucwaningo lwesikhathi esizayo kanye nentuthuko lungathuthukisa ukusebenza kwe-CMC futhi linqobe ukushiyeka kwalo okukhona, ngaleyo ndlela landisa amathuba okusebenza kwalo kumasimu amaningi.
