Methyl hydroxyethyl celluloseyog npaj los ntawm kev qhia txog ethylene oxide substituents (MS0.3 ~ 0.4) rau hauv methyl cellulose, thiab nws qhov kub gel siab dua li ntawm methyl cellulose thiab methyl hydroxypropyl cellulose. , nws cov kev ua tau zoo dua li methyl cellulose thiab methyl hydroxypropyl cellulose.
Methyl hydroxyethyl cellulose feem ntau yog siv ua cov khoom ua kom tuab, stabilizer thiab tiv thaiv colloid hauv cov architectural mortar thiab cov txheej txheem dej.

Cov khoom siv lub cev thiab tshuaj lom neeg
1. Kev yaj: yaj tau hauv dej thiab qee cov kuab tshuaj organic, qhov siab tshaj plaws tsuas yog nyob ntawm qhov viscosity, qhov solubility hloov pauv nrog qhov viscosity, qhov qis dua qhov viscosity, qhov ntau dua qhov solubility.
2. Tsis kam ntsev: Cov khoom yog non-ionic cellulose ether, uas ruaj khov nyob rau hauv cov kua dej, tab sis ntxiv ntau dhau ntawm electrolyte tuaj yeem ua rau gelation thiab nag lossis daus.
3. Kev Ua Haujlwm Ntawm Qhov Chaw: Vim tias cov kua dej muaj kev ua haujlwm ntawm qhov chaw, nws tuaj yeem siv ua tus neeg sawv cev tiv thaiv colloid, emulsifier thiab dispersant.
4. Thermal gel: Thaum cov kua dej ntawm cov khoom raug cua sov rau qee qhov kub, nws dhau los ua opaque, gels, thiab tsim cov precipitate, tab sis thaum nws txias tas li, nws rov qab mus rau lub xeev kua qub.
5. Kev Ua Haujlwm ntawm Cov Khoom Noj: Kev ua haujlwm ntawm cov khoom noj yog inert thiab muaj ntxhiab tsw qab thiab tsw qab tsawg. Vim tias lawv tsis tau ua haujlwm ntawm cov khoom noj thiab muaj ntxhiab tsw qab tsawg, lawv tau siv dav hauv cov khoom noj thiab tshuaj.
6. Kev tiv thaiv kab mob pwm: Nws muaj peev xwm tiv thaiv kab mob pwm zoo thiab ruaj khov viscosity zoo thaum lub sijhawm khaws cia ntev.
7. PH ruaj khov: Qhov viscosity ntawm cov kua dej ntawm cov khoom tsis tshua cuam tshuam los ntawm kua qaub lossis alkali, thiab tus nqi PH ruaj khov nyob rau hauv qhov ntau ntawm 3.0-11.0.
8. Cov tshauv tsawg: Vim tias cov khoom tsis yog ionic, nws tau ua kom zoo los ntawm kev ntxuav nrog dej kub thaum lub sijhawm npaj, yog li nws cov tshauv tsawg heev.
9. Kev khaws cia cov duab: Vim tias cov kua dej uas muaj zog heev ntawm cov khoom muaj cov yam ntxwv tshwj xeeb viscoelastic piv rau cov kua dej ntawm lwm cov polymers, nws qhov ntxiv muaj peev xwm txhim kho cov duab ntawm cov khoom siv ceramic extruded.
10. Kev khaws dej: Qhov hydrophilicity ntawm cov khoom thiab qhov viscosity siab ntawm nws cov kua dej ua rau nws yog ib tus neeg sawv cev khaws dej zoo.

Ntim thiab xa khoom:
Qhov hnyav tag nrho 25 kg, hnab yas sib xyaw ua ke, tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Cov khoom no nqus tau cov dej noo yooj yim thiab yuav tsum tau khaws cia rau qhov chaw txias thiab qhuav.
