1. Imboni kawoyela
I-sodium carboxymethyl cellulose isetshenziswa kakhulu ekukhishweni kwamafutha, asetshenziswa ekwenziweni kodaka, idlala indima ye-viscosity, ukulahleka kwamanzi, ingamelana nokungcola okuhlukahlukene kukasawoti oncibilikayo, ithuthukise izinga lokubuyisa uwoyela.I-sodium carboxymethyl hydroxypropyl cellulose (NaCMHPC) kanye ne-sodium carboxymethyl hydroxyethyl cellulose (NaCMHEC) yizinto ezinhle zokumba udaka nokulungiswa koketshezi oluqedayo, ezinesivuno esikhulu sokudonsa, ukumelana nosawoti omuhle kanye ne-calcium, ikhono elihle elikhulayo le-viscosity nokumelana nokushisa (160 ℃) .Ifanele ukulungiswa kwamanzi ahlanzekile, amanzi olwandle kanye noketshezi lokumba lwamanzi anosawoti agcwele, ngaphansi kwesisindo se-calcium chloride ingalungiswa ibe ukuminyana okuhlukahlukene (103 ~ 127g/cm3) uketshezi lokumba, futhi kuyenze ibe ne-viscosity ethile futhi iphansi. ukulahlekelwa kokuhlunga, i-viscosity yayo kanye nomthamo wokulahlekelwa kokuhlunga kungcono kunoi-hydroxyethyl cellulose, iyizithasiselo ezinhle zokukhiqiza uwoyela.
I-Sodium carboxymethyl cellulose iwumphumela we-cellulose osetshenziswa kabanzi ohlelweni lokuxhashazwa kukawoyela, esetshenziswe kuketshezi lokumba, uketshezi lukasimende, uketshezi oluqhekekayo kanye nokwenza ngcono umthamo wokukhiqiza uwoyela, ikakhulukazi oketshezini lokumba olunomthamo omkhulu, ikakhulukazi ukukhumula nokuhlalisa kanye nokuhlunga. i-viscosification.I-Hydroxyethyl cellulose(HEC) isetshenziselwa ukumba, ukuqedela kanye nezinqubo zikasimende njengendlela yokuqinisa udaka.Uma kuqhathaniswa ne-sodium carboxymethyl cellulose kanye ne-guar gum, i-hydroxyethyl cellulose inezinzuzo zomphumela omuhle wokuqina, isihlabathi esimisiwe esiqinile, okuqukethwe kukasawoti omningi, ukumelana nokushisa okuhle, ukulahlekelwa uketshezi oluphansi, i-glue block ephukile kanye nezinsalela eziphansi.
2. Imboni yokwakha neyokumboza
I-sodium carboxymethyl cellulose, ingxube yodaka lwesakhiwo kanye nodaka lokunameka, ingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-binder, futhi ingasetshenziswa njenge-disperant, i-ejenti yokugcina amanzi kanye ne-thickener ye-plaster, udaka kanye nezinto ezibushelelezi zaphansi ze-gypsum nosimende. phansi.Kuyingxube ekhethekile yokwakhiwa kwamatshe nodaka eyenziwe nge-carboxymethyl cellulose yamabhulokhi kakhonkolo afakwa umoya.Ingathuthukisa ukusebenza, ukugcinwa kwamanzi kanye nokumelana nokuqhekeka kodaka, futhi igweme ukuqhekeka kanye nokuvuleka kwezindonga zamabhulokhi.Izinto zokwakha umhlobiso ongaphezulu kwe-Cao Mingqian et al eyenziwe nge-methyl cellulose iyindawo yokuhlobisa indawo yokwakha enemvelo, inqubo yokukhiqiza ilula, ihlanzekile, ingasetshenziselwa udonga olusezingeni eliphezulu, i-tile surface, ingasetshenziselwa umhlobiso ongaphezulu. wamakholomu namaphilisi.
3. Imboni yamakhemikhali yansuku zonke
I-sodium carboxymethyl cellulose, i-tackifier ezinzile, idlala indima ekuhlakazeni ukuzinza kokumiswa emikhiqizweni yokunamathisela yezinto ezingavuthiwe eziyimpushana, ukuqina, ukuhlakazeka kanye ne-homogenizing kuzimonyo eziwuketshezi noma ze-emulsion.Ingasetshenziswa njenge-stabilizer ne-viscosifier.I-Emulsifying stabilizer isetshenziswa njenge-emulsifier, i-tackifier kanye ne-stabilizer yamafutha kanye ne-shampoo.I-sodium carboxymethyl hydroxypropyl cellulose ingasetshenziswa njenge-adhesive stabilizer ye-toothpaste, enezici ezinhle ze-thixotropic, ukuze umuthi wokuxubha ube nokuhleleka okuhle, ukuguqulwa kwesikhathi eside, ukunambitheka okufanayo nokuthambile.I-sodium carboxymethyl hydroxypropyl cellulose ukumelana nosawoti, ukumelana ne-asidi kuphakeme, umphumela ungcono kakhulu kune-carboxymethyl cellulose, ingasetshenziswa njenge-tackifier ku-detergent, i-ejenti yokuvimbela ukunamathela kokungcola.Ekukhiqizeni okokuhlanza, i-sodium carboxymethyl cellulose ngokuvamile isetshenziswa njenge-disperant yokungcola yempushana yokuwasha, i-thickener kanye ne-disperant yokuhlanza uketshezi.
4. Imboni yezemithi nokudla
Embonini yezemithi,i-hydroxypropyl carboxymethyl cellulose(i-HPMC) ingasetshenziswa njengezihlanganisi zezidakamizwa, ezisetshenziswa kabanzi ekukhululweni okulawulwa kwamathambo ezidakamizwa ngomlomo kanye namalungiselelo okukhululwa okuqhubekayo, njengento evimbela ukukhululwa ukuze ulawule ukukhishwa kwezidakamizwa, njenge-coating material ekhululayo esebenza ngokuqhubekayo, i-pellets yokukhululwa okuqhubekayo, amaphilisi okukhululwa okuqhubekayo. .Okusetshenziswa kakhulu i-methyl carboxymethyl cellulose, i-ethyl carboxymethyl cellulose, efana ne-MC ivame ukusetshenziswa ekwenzeni amaphilisi namaphilisi, noma amaphilisi kashukela amboziwe.Ikhwalithi ephezului-cellulose etherszingasetshenziswa embonini yokudla, futhi zingama-thickeners asebenzayo, ama-stabilizers, ama-excipients, ama-ejenti okugcina amanzi kanye nama-foaming ejenti ayimishini ekudleni okuhlukahlukene.I-methylcellulose kanyei-hydroxypropyl methylcellulosebaqashelwe
Into engasebenzi kahle ye-metabolic engeyona ingozi kusayensi yokwakheka komzimba.Ukuhlanzeka okuphezulu (99.5% noma ngaphezulu ubumsulwa)i-carboxymethyl cellulose(CMC) ingezwa ekudleni okufana nobisi nemikhiqizo kakhilimu, izinongo, ojamu, ojeli besikhumba, amathini, amasyrups etafula kanye neziphuzo.I-Carboxymethyl cellulose enobumsulwa obungaphezu kuka-90% ingasetshenziswa ezicini ezihlobene nokudla, njengokuthuthwa nokugcinwa kwezithelo ezintsha.Lokhu kugoqa kwepulasitiki kunezinzuzo zomphumela omuhle wokulondoloza, ukungcola okuncane, akukho monakalo, kanye nokwenza lula kokukhiqiza ngemishini.
5. Izinto zokusebenza ze-Optical nezikagesi
Ngenxa yokuhlanzeka okuphezulu kwei-cellulose ether, ukumelana okuhle kwe-asidi, ukumelana nosawoti, ikakhulukazi okuqukethwe okuphansi kwensimbi nezinsimbi ezinzima, i-colloidal elungiselelwe izinzile kakhulu, ifanele amabhethri e-alkaline, amabhethri e-zinc-manganese i-electrolyte thickening stabilizer.Abaningii-cellulose ethersbonisa izakhiwo zekristalu ye-thermotropic liquid.I-acetyli-hydroxypropyl celluloseyakha amakristalu e-thermogenic cholesteric liquid ngaphansi kwe-164 ℃.
