I-Carboxymethyl Cellulose (CMC)
Imininingwane Yomkhiqizo
Imininingwane enikeziwe
I-flocculent fiber powder emhlophe noma ephuzi okuqukethwe ≥ 99%
(Ububanzi bereferensi yesicelo 'ukusetshenziswa komkhiqizo')
Ilungiswa ngokuphuma kokunye okuphuma ku-cellulose kwe-carboxymethyl substituents, ephathwa nge-sodium hydroxide ukwenza i-alkali cellulose, bese isabela nge-monochloroacetic acid.Iyunithi ye-glucose eyenza i-cellulose inamaqembu amathathu e-hydroxyl eshintshwayo, ngakho imikhiqizo enamazinga ahlukene okushintsha ingatholakala.Uma i-1mmol carboxymethyl yethulwa nge-1g yesisindo esomile ngokwesilinganiso, ayincibiliki emanzini futhi ixube i-asidi, kodwa ingavuvuka futhi isetshenziselwe i-ion exchange chromatography.I-Carboxymethyl pKa, cishe i-4 emanzini ahlanzekile kanye ne-3.5 ku-0.5mol/L NaCl, i-acidic cation exchanger ebuthakathaka, ngokuvamile isetshenziselwa ukuhlukaniswa kwamaprotheni angathathi hlangothi nayisisekelo ku-pH> 4. Uma iqembu le-hydroxyl elingaphezu kuka-40% kuyi-carboxymethyl, ingancibilika emanzini ukwenza isisombululo esizinzile se-colloidal nge-viscosity ephezulu.
I-EVERBRIGHT® 'izophinda ihlinzeke ngendlela oyifisayo :okuqukethwe/ubumhlophe/usayizi wezinhlayiya/PHvalue/umbala/isitayela sokupakisha/ ukucaciswa kwephakheji neminye imikhiqizo eqondene nezimo zakho zokusebenzisa, futhi ikunikeze amasampula amahhala.

Ukusetshenziswa komkhiqizo
I-Carboxymethyl cellulose (CMC) iyi-flocculent powder engenabuthi futhi engenambimbi esebenza kahle futhi kulula ukuyincibilika emanzini.Isixazululo saso esinamanzi siwuketshezi lwe-viscous olungathathi hlangothi noma olune-alkaline, luncibilika kwezinye izinto ezinamathelayo nezincibilika emanzini, futhi aluncibiliki kuzincibilikisi zemvelo njenge-ethanol.I-CMC ingasetshenziswa njenge-binder, thickener, susspension agent, emulsifier, dispersant, stabilizer, sizing agent, njll. I-Carboxymethyl cellulose (CMC) iyisivuno esikhulu kunazo zonke se-cellulose ether, esetshenziswa kabanzi kakhulu, umkhiqizo olula kakhulu, owaziwa ngokuthi " I-MSG yezimboni".
Ukuhlanza
1. I-sodium carboxymethyl cellulose iyi-surfactant, engasetshenziswa njenge-anti-fouling re-deposition, eyi-dispersant kanye ne-surfactant yezinhlayiya zamabala, eyenza ungqimba oluqinile lwe-adsorption ebaleni ukuvimbela ukuphinda kufakwe ku-fiber. .
2. Uma i-sodium carboxymethyl cellulose yengezwa ku-washing powder, isixazululo singahlakazwa ngokulinganayo futhi sikhangiswe kalula ebusweni bezinhlayiya eziqinile, senze ungqimba lwe-hydrophilic adsorption ezungeze izinhlayiya eziqinile.Khona-ke ukungezwani okungaphezulu phakathi koketshezi kanye nezinhlayiya eziqinile kungaphansi kokucindezeleka kwendawo ngaphakathi kwezinhlayiya eziqinile, futhi umphumela wokumanzisa we-molecule ye-surfactant ubhubhisa ukuhlangana phakathi kwezinhlayiya eziqinile.Lokhu kuhlakaza ukungcola emanzini.
3. I-sodium carboxymethyl cellulose yengezwa ku-powder yokuwasha, enomphumela we-emulsifying.Ngemuva kwe-emulsifying uwoyela esikalini, akulula ukuqoqa kanye nemvula engutsheni.
4. I-sodium carboxymethyl cellulose yengezwe ku-powder yokuwasha, enomphumela wokumanzisa futhi ingangena ezinhlayiyeni zokungcola kwe-hydrophobic, ukuchoboza izinhlayiya zokungcola zibe yizinhlayiya ze-colloidal, ukuze ukungcola kube lula ukushiya i-fiber.
Ukwengezwa kokudla
I-CMC isetshenziswa kabanzi embonini yokudla, ezinhlobonhlobo zeziphuzo zobisi, ama-condiments, idlala indima yokuqina, ukuzinzisa kanye nokwenza ngcono ukunambitheka, ku-ayisikhilimu, isinkwa nama-pastes, ama-noodle asheshayo kanye nama-pastes osheshayo nokunye ukudla, ukudlala indima. ukwakha, ukuthuthukisa ukunambitheka, ukugcina amanzi, ukuqinisa ukuqina nokunye.Phakathi kwazo, i-FH9, i-FVH9, i-FM9 ne-FL9 inokusimama okuhle kwe-asidi.Imikhiqizo yohlobo oluphezulu engeziwe inezindawo ezinhle zokujiya.I-CMC ingaxazulula ngempumelelo inkinga yokuhlukaniswa koketshezi oluqinile kanye nemvula yesiphuzo se-lactic acid lapho okuqukethwe kwamaprotheni kungaphezu kuka-1%, futhi kungenza ubisi lwe-lactic acid lube nokunambitheka okuhle.Ubisi olukhiqiziwe lwe-lactic lungagcina uzinzo ku-PH uhla lwe-3.8-4.2, lungamelana ne-pasteurization kanye nenqubo yokuvala inzalo esheshayo engu-135℃, ikhwalithi yomkhiqizo izinzile futhi ithembekile, futhi ingagcinwa ezingeni lokushisa elivamile isikhathi esingaphezu kwezinyanga eziyisithupha.Ukwakheka kokuqala okunomsoco kanye nokunambitheka kweyogathi kuhlala kungashintshile.U-ayisikhilimu one-CMC, ungavimbela ukukhula kwamakristalu e-ayisikhilimu, ukuze u-ayisikhilimu unambitheke bushelelezi uma udla, unganamathelani, unamafutha, ukhuluphele kanye nokunye ukunambitheka okubi.Ngaphezu kwalokho, izinga lokuvuvukala liphezulu, futhi ukumelana nezinga lokushisa nokumelana nokuncibilika kuhle.I-CMC yama-noodle asheshayo yenza ama-noodle asheshayo abe nokuqina okuhle, ukunambitheka okuhle, ukuma okuphelele, i-turbidity ephansi yesobho, futhi inganciphisa okuqukethwe kukawoyela (cishe ngo-20% ngaphansi kokusetshenziswa kukaphethiloli kwasekuqaleni).
Uhlobo lokuhlanzeka okuphezulu
I-CMC yebanga lephepha isetshenziselwa ukulinganisa iphepha, ukuze iphepha libe nokuminyana okuphezulu kakhulu, ukungena kahle kweyinki, kungathuthukisa ukunamathela phakathi kwemicu engaphakathi ephepheni, ngaleyo ndlela kuthuthukiswe ukumelana nephepha nokugoqa.Thuthukisa ukunamathela kwangaphakathi kwephepha, unciphise uthuli lokuphrinta ngesikhathi sokuphrinta, noma ngisho nothuli lungekho.Ingaphezulu lephepha ukuthola ukuvalwa okuhle nokumelana nowoyela ukuthuthukisa ikhwalithi yokuphrinta.Ingaphezulu lephepha lithuthukisa ukukhanya, linciphisa i-porosity, futhi lidlala indima yokugcina amanzi.Kuyasiza ukuhlakaza i-pigment, yelule impilo ye-scraper, futhi inikeze uketshezi olungcono, izakhiwo ze-optical kanye nokuzivumelanisa nokuphrinta kokwakhiwa kokuqukethwe okuqinile okuphezulu.
Ibanga lokuxubha amazinyo
I-CMC ine-pseudoplasticity enhle, i-thixotropy kanye ne-aftergrowth.I-paste ye-toothpaste izinzile, ukungaguquguquki kuyafaneleka, ukuhleleka kuhle, umuthi wokuxubha awumanzi, awucwebi, awukhiqizi, unamathisele ugqamile futhi uthambile, uthambile futhi umelana nokushintsha kwezinga lokushisa.Ukuhambisana okuhle nezinto ezihlukahlukene zokusetshenziswa ku-toothpaste;Ingadlala indima enhle ekubumbeni, ekuhlanganiseni, ekunyakaziseni nasekulungiseni amakha.
Okukhethekile kuma-ceramics
Emkhiqizweni we-ceramic, asetshenziswa ngokulandelana ku-embryo ye-ceramic, i-glaze paste kanye ne-floral glaze.I-Ceramic grade CMC isetshenziswa njenge-binder engenalutho ku-ceramic billet ukuze kuthuthukiswe amandla kanye nepulasitiki ye-billet.Thuthukisa isivuno.Ku-ceramic glaze, ingavimbela ukuna kwezinhlayiya ezicwebezelayo, ithuthukise ikhono lokunamathela le-glaze, ithuthukise ukuhlangana kwe-glaze engenalutho futhi ithuthukise amandla ongqimba olucwebezelayo.Inokungena kahle nokuhlakazeka ku-glaze yokunyathelisa, ukuze i-glaze yokunyathelisa izinzile futhi ifane.
Indawo kawoyela ekhethekile
Inezici zama-molecule afaka esikhundleni esifanayo, ukuhlanzeka okuphezulu kanye nesilinganiso esincane, esingathuthukisa ukusebenza kahle kwenqubo yodaka.Ukumelana nomswakama omuhle, ukumelana nosawoti kanye nokumelana ne-alkaline, kulungele ukuxutshwa nokusetshenziswa kwamanzi anosawoti agcwele kanye namanzi olwandle.Ilungele ukulungiswa kwempushana kanye nesikhathi esifushane sokuqina emkhakheni wokuxhashazwa kwamafutha.I-Polyanionic cellulose (PAC-HV) iyi-viscosifier esebenza kahle kakhulu enesivuno esiphezulu se-pulp kanye nekhono lokunciphisa ukulahlekelwa kwamanzi odakeni.I-Polyanionic cellulose (PAC-LV) iyisinciphisi esihle kakhulu sokulahlekelwa uketshezi odakeni, esikwazi ukulawula kahle ukulahleka kwamanzi odakeni lwamanzi olwandle nodaka lwamanzi anosawoti agcwele.Ifanele uhlelo lodaka olunzima ukulawula okuqukethwe okuqinile kanye noshintsho olubanzi.I-CMC, njenge-gel fracturing fluid, inezici ze-gelatinability enhle, umthamo oqinile wokuthwala isihlabathi, umthamo wokuphuka kwerabha kanye nezinsalela eziphansi.
