1. Imboni kawoyela
I-sodium carboxymethyl celluloseisetshenziswa kakhulu ekukhishweni kukawoyela, futhi isetshenziswa ekwenzeni udaka ukuze kwandiswe i-viscosity nokunciphisa ukulahleka kwamanzi. Ingakwazi ukumelana nokungcola okuhlukahlukene kukasawoti oncibilikayo futhi yandise ukubuyiswa kukawoyela. I-sodium carboxymethyl hydroxypropyl cellulose (NACMHPC) kanye ne-sodium carboxymethyl hydroxyethyl cellulose (NACMHEC) ama-ejenti amahle okumba udaka kanye nezinto zokwakha zokulungiselela uketshezi oluqedayo, olunezinga eliphezulu lokudumba nokumelana nosawoti, Ukusebenza okuhle kwe-anti-calcium, ikhono elihle lokukhulisa i-viscosity, ukumelana nokushisa (160 ℃). Ilungele ukulungiselela uketshezi lokumba lwamanzi ahlanzekile, amanzi olwandle namanzi anosawoti agcwele. Ingakhiwa ibe uketshezi lokumba lokuminyana okuhlukahlukene (103-127g/cm3) ngaphansi kwesisindo se-calcium chloride, futhi ine-viscosity ethile nokulahlekelwa uketshezi oluphansi, ikhono layo lokukhulisa i-viscosity kanye nekhono lokunciphisa uketshezi lokunciphisa lingcono kune-hydroxyethyl cellulose, futhi iyisengezo esihle sokwandisa ukukhiqizwa kukawoyela.
I-sodium carboxymethyl cellulose iphuma ku-cellulose esetshenziswa kabanzi enqubweni yokukhipha uwoyela. Isetshenziselwa uketshezi lokumba, uketshezi lukasimende, uketshezi oluqhekekayo kanye nokwenza ngcono ukutholakala kukawoyela, ikakhulukazi oketshezini lokumba. Ngokuyinhloko idlala indima yokunciphisa ukulahlekelwa uketshezi nokwandisa i-viscosity. I-Hydroxyethyl cellulose (HEC) isetshenziswa njenge-ejenti yokuqina nokuqinisa udaka ngesikhathi sokumba, ukuqeda kahle nokufaka usimende. Uma kuqhathaniswa ne-sodium carboxymethyl cellulose ne-guar gum, i-hydroxyethyl cellulose inomphumela omuhle wokujiya, ukumiswa kwesihlabathi okuqinile, umthamo omkhulu kasawoti, ukumelana nokushisa okuhle, ukumelana nokuxubana okuncane, ukulahlekelwa okuncane koketshezi, nokuphuka kwejeli. I-block, izinsalela eziphansi nezinye izici, isetshenziswe kabanzi.
2. Ukwakha, imboni kapende
I-sodium carboxymethyl cellulose ingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-binder yokwakha amatshe kanye nengxube yodaka, futhi ingasetshenziswa njenge-plaster, udaka kanye nezinto zokulinganisa umhlabathi zesisekelo se-gypsum kanye nesisekelo sikasimende Isetshenziswa njenge-dispersor, i-ejenti egcina amanzi kanye ne-thickener. Ingxube ekhethekile ye-masonry kanye ne-plastering mortar eyenziwe nge-carboxymethyl cellulose, engathuthukisa ukusebenza, ukugcinwa kwamanzi kanye nokumelana nokuqhekeka kodaka, futhi igweme ukuqhekeka nokuvaleka odongeni lwebhulokhi. isigubhu. Izinto zokwakha umhlobiso ongaphezulu u-Cao Mingqian nabanye benza into yokuhlobisa indawo yokwakha evumelana nemvelo nge-methyl cellulose. Inqubo yokukhiqiza ilula futhi ihlanzekile. Ingasetshenziselwa udonga olusezingeni eliphezulu kanye nezindawo zamathayela wamatshe, futhi ingasetshenziselwa ukuhlobisa ngaphezulu kwamakholomu nezikhumbuzo.
3. Imboni yamakhemikhali yansuku zonke
I-viscosifier yokuqinisa i-sodium carboxymethyl cellulose idlala indima yokuhlakazeka nokumiswa kokuqina emikhiqizweni yokunamathisela yezinto ezingavuthiwe zempushana, futhi idlala indima yokujiya, ihlakaze kanye ne-homogenizing kuzimonyo eziwuketshezi noma ze-emulsion. Ingasetshenziswa njenge-stabilizer kanye ne-tackifier. Ama-Emulsion stabilizer asetshenziswa njengama-emulsifiers, ama-thickeners nama-stabilizer wamafutha okugcoba nama-shampoos. I-sodium carboxymethyl hydroxypropyl cellulose ingasetshenziswa njengesiqinisi sezinto zokunamathela zokuxubha amazinyo. Inezici ezinhle ze-thixotropic, okwenza umuthi wokuxubha ube muhle ekufomeni, ukugcina isikhathi eside ngaphandle kokuguqulwa, kanye nokunambitheka okufanayo nokuthambile. I-sodium carboxymethyl hydroxypropyl cellulose inokumelana nosawoti okuphakeme nokumelana ne-asidi, futhi umphumela wayo uphakeme kakhulu kunalowo we-carboxymethyl cellulose. Ingasetshenziswa njenge-thickener ku-detergents kanye ne-anti-stain agent. I-dispersion thickener ekukhiqizeni okokuhlanza, i-sodium carboxymethylcellulose ngokuvamile isetshenziswa njengesisabalalisi sokungcola sempushana yokuwasha, i-thickener kanye ne-disperant yezinto zokuhlanza uketshezi.
4. Imithi, imboni yokudla
Embonini yezemithi,i-hydroxypropyl carboxymethylcellulose (HPMC)ingasetshenziswa njengesamukeli sezidakamizwa, esisetshenziswa kakhulu ekukhululweni okulawulwa yi-matrix yezidakamizwa ngomlomo kanye namalungiselelo okukhululwa okuqhubekayo, njengento ebambezela ukukhululwa ukuze kulawuleke ukukhishwa kwezidakamizwa, nanjengento yokumboza ukuze kubambezeleke ukukhululwa kwezidakamizwa. Amafomu okukhishwa, ama-pellets akhululiwe, ama-capsules akhululiwe. Okusetshenziswa kakhulu i-methyl carboxymethyl cellulose ne-ethyl carboxymethyl cellulose, njenge-MC, evame ukusetshenziselwa ukwenza amaphilisi namaphilisi, noma ukumboza amaphilisi ambozwe ngoshukela. Ama-ether e-cellulose esezingeni le-premium angasetshenziswa embonini yokudla futhi angama-thieners asebenzayo, ama-stabilizer, ama-excipients, ama-ejenti agcina amanzi kanye nama-agent akhipha amagwebu ayimishini ekudleni okuhlukahlukene. I-Methyl cellulose kanye ne-hydroxypropyl methyl cellulose kuye kwaqashelwa njengezinto ezingenabungozi ze-metabolic ezingenabungozi. I-High-purity (ngaphezu kuka-99.5%) i-carboxymethylcellulose (CMC) ingafakwa ekudleni, njengobisi nemikhiqizo kakhilimu, izinongo, ujamu, ijeli, ukudla okusemathinini, isiraphu yetafula neziphuzo. I-Carboxymethyl cellulose enobumsulwa obungaphezu kuka-90% ingasetshenziswa ezicini ezihlobene nokudla, njengokuthuthwa nokugcinwa kwezithelo ezintsha. Lolu hlobo lokugoqa kwepulasitiki lunobuhle bomphumela omuhle wokugcina, ukungcoliswa okuncane, akukho monakalo, nokukhiqiza kalula ngemishini.
5. Izinto zokusebenza ze-Optical nezikagesi
I-Electrolyte thickening stabilizer inokuhlanzeka okuphezulu kwe-cellulose ether, ukumelana ne-asidi enhle nokumelana nosawoti, ikakhulukazi insimbi ephansi kanye nokuqukethwe kwensimbi esindayo, ngakho-ke i-colloid izinzile kakhulu, ifanele amabhethri e-alkaline, amabhethri e-zinc-manganese I-Electrolyte thickening stabilizer. Ama-cellulose ether amaningi abonisa i-thermotropic liquid crystallinity. IHydroxypropyl cellulose acetate yakha amakristalu e-thermotropic cholesteric liquid angaphansi kuka-164°C.
