1. Isingeniso esifushane seCarboxymethyl Cellulose
Igama lesiNgisi: Carboxyl methyl Cellulose
Isifinyezo: CMC
Ifomula yamangqamuzana iyahlukahluka: [C6H7O2(OH)2CH2COONA]n
Ukubukeka: emhlophe noma ephuzi ekhanyayo ene-fibrous granular powder.
Ukunyibilika kwamanzi: kuncibilika kalula emanzini, kwakha i-viscous colloid esobala, futhi isisombululo asithathi hlangothi noma sine-alkaline kancane.
Izici: Inhlanganisela yamangqamuzana ephezulu ye-colloid esebenzayo, engenaphunga, ayinambitheki futhi ayinabuthi.
I-cellulose yemvelo isatshalaliswa kabanzi emvelweni futhi iyi-polysaccharide eningi kakhulu. Kodwa ekukhiqizeni, i-cellulose ivame ukuba khona ngesimo se-sodium carboxymethyl cellulose, ngakho igama eligcwele kufanele kube i-sodium carboxymethyl cellulose, noma i-CMC-Na. Kusetshenziswa kabanzi embonini, ekwakhiweni, kwezokwelapha, ekudleni, kwendwangu, kweze-ceramics nakweminye imikhakha.
2. Ubuchwepheshe be-Carboxymethyl cellulose
Ubuchwepheshe bokuguqula i-cellulose buhlanganisa: i-etherification kanye ne-esterification.
Ukuguqulwa kwe-carboxymethyl cellulose: ukusabela kwe-carboxymethylation kubuchwepheshe be-etherification, i-cellulose i-carboxymethylated ukuze ithole i-carboxymethyl cellulose, ebizwa ngokuthi i-CMC.
Imisebenzi yesisombululo samanzi se-carboxymethyl cellulose: ukuqina, ukwakheka kwefilimu, ukubopha, ukugcinwa kwamanzi, ukuvikelwa kwe-colloid, i-emulsification nokumiswa.
3. Ukusabela kwamakhemikhali kwe-carboxymethyl cellulose
Ukusabela kwe-cellulose alkalization:
[C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ]n + nH2O
Ukusabela kwe-etherification ye-monochloroacetic acid ngemuva kwe-alkali cellulose:
[C6H7O2(OH) 2ONa ]n + nClCH2COONA →[C6H7O2(OH) 2OCH2COONA ]n + nNaC
Ngakho-ke: ifomula yamakhemikhali yokwenza i-carboxymethyl cellulose yile: Cell-O-CH2-COONA NaCMC
I-sodium carboxymethyl cellulose(I-NaCMC noma i-CMC ngamafuphi) iyi-ether ye-cellulose encibilika emanzini engenza i-viscosity yezixazululo zesisombululo samanzi ezisetshenziswa kakhulu ihluke ukusuka ku-cP embalwa ukuya ezinkulungwaneni ezimbalwa ze-cP.
4. Izici zomkhiqizo we-carboxymethyl cellulose
1. Ukugcinwa kwesisombululo samanzi se-CMC: Izinzile ngaphansi kwezinga lokushisa eliphansi noma ukukhanya kwelanga, kodwa i-acidity ne-alkalinity yesisombululo izoshintsha ngenxa yezinguquko zokushisa. Ngaphansi kwethonya lemisebe ye-ultraviolet noma ama-microorganisms, i-viscosity yesisombululo izokwehla noma yonakaliswe. Uma kudingeka ukugcinwa isikhathi eside, i-preservative efanele kufanele yengezwe.
2. Indlela yokulungiselela yesisombululo samanzi se-CMC: yenza izinhlayiya zibe manzi ngokulinganayo kuqala, ezingakhuphula kakhulu izinga lokuqedwa.
3. I-CMC iyi-hygroscopic futhi kufanele ivikelwe kumswakama ngesikhathi sokugcinwa.
4. Usawoti wensimbi esindayo njenge-zinc, ithusi, umthofu, i-aluminium, isiliva, insimbi, ithini, ne-chromium angabangela i-CMC ukuba idle.
5. Imvula ivela esixazululweni esinamanzi esingaphansi kuka-PH2.5, esingabuyiswa ngemva kokunciphisa ngokwengeza i-alkali.
6. Nakuba usawoti onjenge-calcium, i-magnesium nosawoti wetafula ungenawo umthelela wemvula ku-CMC, uzonciphisa i-viscosity yesisombululo.
7. I-CMC iyahambisana namanye ama-glues ancibilika emanzini, izinto ezithambisayo nama-resin.
8. Ngenxa yokucubungula okuhlukile, ukubonakala kwe-CMC kungaba yimpushana enhle, okusanhlamvu okuqinile noma i-fibrous, engahlangene nezakhiwo zomzimba namakhemikhali.
9. Indlela yokusebenzisa i-CMC powder ilula. Ingafakwa ngokuqondile futhi ichithwe emanzini abandayo noma emanzini afudumele ku-40-50 ° C.
5. Izinga lokushintsha nokuncibilika kwe-carboxymethyl cellulose
Izinga lokushintsha libhekisela enanini eliyisilinganiso lamaqembu e-sodium carboxymethyl axhunywe kuyunithi ngayinye ye-cellulose; inani eliphezulu lezinga lokushintshwa ngu-3, kodwa eliwusizo kakhulu ngokwezimboni i-NaCMC enezinga lokushintsha elihluka ukusuka ku-0.5 ukuya ku-1.2. Izakhiwo ze-NaCMC ezinezinga lokushintshwa kwe-0.2-0.3 zihluke kakhulu kulezo ze-NaCMC ngezinga lokushintshwa elingu-0.7-0.8. Owokuqala uncibilika kancane kuphela emanzini angu-pH 7, kodwa okugcina kuncibilika ngokuphelele. Okuphambene kuyiqiniso ngaphansi kwezimo ze-alkaline.
6. I-polymerization degree kanye ne-viscosity ye-carboxymethyl cellulose
I-Polymerization degree: ibhekisela kubude beketango le-cellulose, elinquma i-viscosity. Uma iketango le-cellulose lide, i-viscosity inkulu, kanjalo nesisombululo se-NaCMC.
I-Viscosity: Isixazululo se-NaCMC siwuketshezi olungezona olwase-Newton, futhi i-viscosity yayo esobala iyehla lapho amandla okugunda akhuphuka. Ngemva kokumisa ukugubha, i-viscosity yanda ngokulinganayo kuze kube yilapho izinzile. Okusho ukuthi, ikhambi liyi-thixotropic.
