Methyl Hydroxyethyl Cellulose MHEC

I-Methyl hydroxyethyl cellulose ilungiswe ngokuzisa i-ethylene oxide substituents (MS0.3 ~ 0.4) kwi-methyl cellulose, kwaye ubushushu bayo be-gel buphezulu kune-methyl cellulose kunye ne-methyl hydroxypropyl cellulose. , ukusebenza kwayo okubanzi kubhetele kune-methyl cellulose kunye ne-methyl hydroxypropyl cellulose.

I-Methyl hydroxyethyl cellulose isetyenziswa kakhulu njenge-thickener, stabilizer kunye ne-colloid yokukhusela kwi-architectural mortar kunye neengubo ezisekelwe emanzini.

Iimpawu zomzimba kunye neekhemikhali

1. I-Solubility: i-solubility emanzini kunye nezinye i-solvents eziphilayo, i-concentration ephezulu ixhomekeke kuphela kwi-viscosity, utshintsho lwe-solubility kunye ne-viscosity, i-viscosity ephantsi, i-solubility enkulu.

2. Ukumelana netyuwa: Imveliso i-ether ye-cellulose engekho i-ionic, ezinzileyo kwisisombululo esinamanzi, kodwa ukongezwa okugqithisileyo kwe-electrolyte kunokubangela i-gelation kunye nemvula.

3. Umsebenzi womphezulu: Ngenxa yokuba isisombululo samanzi sinomsebenzi womsebenzi ongaphezulu, sinokusetyenziswa njenge-agent ekhuselayo ye-colloid, i-emulsifier kunye ne-dispersant.

4. Ijeli ye-Thermal: Xa isisombululo se-aqueous semveliso sifudumala kwiqondo lokushisa elithile, liba li-opaque, i-gels, kwaye lenze i-precipitate, kodwa xa licolile ngokuqhubekayo, libuyela kwimeko yesisombululo sokuqala.

5. I-Metabolism: I-Metabolism ine-inert kwaye inevumba eliphantsi kunye nevumba elimnandi. Ngenxa yokuba azikho i-metabolized kwaye zinevumba eliphantsi kunye nevumba elimnandi, zisetyenziswa kakhulu ekutyeni nakumayeza.

6. Ukunganyangeki kokungunda: Inamandla okuthintela ukubola kunye nokuzinza okuhle kwe-viscosity ngexesha lokugcinwa kwexesha elide.

7. Ukuzinza kwe-PH: I-viscosity yesisombululo se-aqueous yemveliso ayinakuchaphazeleka nge-asidi okanye i-alkali, kwaye ixabiso le-PH lizinzile kuluhlu lwe-3.0-11.0.

8. Isiqulatho somlotha ophantsi: Ekubeni imveliso i-non-ionic, ihlanjululwa ngokufanelekileyo ngokuhlamba ngamanzi atshisayo ngexesha lokulungiselela inkqubo, ngoko umxholo wayo womlotha uphantsi kakhulu.

9. Ukugcinwa kobume: Ekubeni isisombululo esinamanzi esixutywe kakhulu semveliso sineempawu ezikhethekileyo ze-viscoelastic xa kuthelekiswa nezisombululo zamanzi zezinye iipolymers, ukongezwa kwayo kunamandla okuphucula imilo yeemveliso ze-ceramic ezikhutshiweyo.

10. Ukugcinwa kwamanzi: I-hydrophilicity yemveliso kunye ne-viscosity ephezulu yesisombululo sayo samanzi yenza ukuba i-agent esebenzayo yokugcina amanzi.

Isicelo:
iglu yethayile
Ukutyabeka udaka, i-grout, i-caulk
Udaka lwe-insulation
ukuziphakamisa
Ipeyinti yodonga lwangaphakathi nangaphandle (ipeyinti yamatye yokwenyani)

Ukupakisha kunye nokuthumela ngenqanawa:
I-25 kg ye-net weight, i-paper-plastic composite bag, inokwenziwa ngokwezifiso ngokweemfuno zabathengi.
Le mveliso ithatha umswakama ngokulula kwaye kufuneka igcinwe kwindawo epholileyo, eyomileyo.
