I-Methyl hydroxyethyl celluloseilungiswa ngokungenisa izinto ezithatha indawo ye-ethylene oxide (MS0.3~0.4) ku-methyl cellulose, futhi izinga lokushisa layo lejeli liphakeme kunele-methyl cellulose kanye ne-methyl hydroxypropyl cellulose. , ukusebenza kwayo okuphelele kungcono kune-methyl cellulose kanye ne-methyl hydroxypropyl cellulose.
I-Methyl hydroxyethyl cellulose isetshenziswa kakhulu njenge-thickener, stabilizer kanye ne-colloid evikelayo e-mortar yezakhiwo kanye ne-water-based coatings.

Izakhiwo zomzimba nezamakhemikhali
1. Ukuncibilika: kuncibilika emanzini nakwezinye izinyibilikisi eziphilayo, ukuhlushwa okuphezulu kuncike kuphela ku-viscosity, ukuncibilika kuyashintsha nge-viscosity, lapho i-viscosity incipha, kulapho ukuncibilika kuba kukhulu khona.
2. Ukumelana nosawoti: Lo mkhiqizo uyi-non-ionic cellulose ether, ezinzile kakhulu kwisisombululo samanzi, kodwa ukwengezwa ngokweqile kwe-electrolyte kungabangela i-gelation kanye nemvula.
3. Umsebenzi womphezulu: Ngenxa yokuthi isixazululo samanzi sinomsebenzi womsebenzi womphezulu, singasetshenziswa njenge-ejenti yokuvikela ye-colloid, i-emulsifier kanye ne-dispersant.
4. Ijeli Yokushisa: Uma isixazululo samanzi somkhiqizo sishiswa kufikela ekushiseni okuthile, siba yi-opaque, sibe amajeli, bese sakha i-precipitate, kodwa uma sipholiswa njalo, sibuyela esimweni sokuqala sesisombululo.
5. Ukwakheka Kwezinto Eziphilayo: Ukwakheka kwezinto eziphilayo akusebenzi futhi kunephunga nephunga eliphansi. Ngenxa yokuthi azigaywanga futhi zinephunga nephunga eliphansi, zisetshenziswa kakhulu ekudleni nakwezokwelapha.
6. Ukumelana nokukhunta: Inamandla amahle okulwa nokukhunta kanye nokuqina okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.
7. Ukuqina kwe-PH: I-viscosity yesisombululo samanzi somkhiqizo ayithinteki kakhulu yi-asidi noma i-alkali, futhi inani le-PH lizinzile phakathi kuka-3.0-11.0.
8. Okuqukethwe komlotha okuphansi: Njengoba umkhiqizo ungeyona i-ionic, ucwengisiswa kahle ngokugezwa ngamanzi ashisayo ngesikhathi senqubo yokulungiselela, ngakho-ke okuqukethwe komlotha wawo kuphansi kakhulu.
9. Ukugcinwa komumo: Njengoba isixazululo samanzi esigxile kakhulu somkhiqizo sinezakhiwo ezikhethekile ze-viscoelastic uma siqhathaniswa nezixazululo zamanzi zamanye ama-polymer, ukwengeza kwaso kunekhono lokuthuthukisa ukuma kwemikhiqizo ye-ceramic ekhishwe.
10. Ukugcinwa kwamanzi: Ukunamathela kwamanzi komkhiqizo kanye nokuthambekela okuphezulu kwesisombululo sawo samanzi kuwenza ube yinto ephumelelayo yokugcina amanzi.

Ukupakisha nokuthumela:
Isisindo esiphelele esingu-25 kg, isikhwama esihlanganisiwe sephepha-plastiki, singenziwa ngokwezifiso ngokwezidingo zamakhasimende.
Lo mkhiqizo umunca umswakama kalula futhi kufanele ugcinwe endaweni epholile, eyomile.
