I-Methyl hydroxyethyl celluloseIlungiswa ngokungenisa izinto ezithatha indawo ze-ethylene oxide (MS0.3 ~ 0.4) kwi-methyl cellulose, kwaye ubushushu bayo bejeli buphezulu kunobo be-methyl cellulose kunye ne-methyl hydroxypropyl cellulose. , ukusebenza kwayo okupheleleyo kungcono 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 ne-water-based coatings.

Iimpawu zomzimba nezekhemikhali
1. Ukunyibilika: xa inyibilika emanzini nakwezinye izinyibilikisi zendalo, uxinaniso oluphezulu luxhomekeke kuphela kwi-viscosity, ukunyibilika kuyatshintsha kunye ne-viscosity, kokukhona i-viscosity iphantsi, kokukhona ukunyibilika kukhulu.
2. Ukumelana netyuwa: Le mveliso yi-non-ionic cellulose ether, ezinzileyo kwisisombululo samanzi, kodwa ukongezwa kakhulu kwe-electrolyte kunokubangela i-gelation kunye nemvula.
3. Umsebenzi womphezulu: Ngenxa yokuba isisombululo samanzi sinomsebenzi womsebenzi womphezulu, singasetyenziswa njenge-arhente yokukhusela i-colloid, i-emulsifier kunye ne-dispersant.
4. Ijeli yobushushu: Xa isisombululo samanzi semveliso sishushu ukuya kubushushu obuthile, siba yi-opaque, iijeli, kwaye senza i-precipitate, kodwa xa ipholiswa rhoqo, ibuyela kwimeko yesisombululo sokuqala.
5. I-Metabolism: I-Metabolism ayisebenzi kwaye inevumba nevumba eliphantsi. Ngenxa yokuba azigaywanga kwaye zinevumba nevumba eliphantsi, zisetyenziswa kakhulu ekutyeni nakwezonyango.
6. Ukumelana nokungunda: Inamandla okulwa nokungunda kunye nozinzo oluhle lokuthamba ngexesha lokugcina ixesha elide.
7. Uzinzo lwe-PH: Ukuqina kwesisombululo samanzi semveliso akuchaphazeleki kakhulu yi-asidi okanye i-alkali, kwaye ixabiso le-PH lizinzile kuluhlu lwe-3.0-11.0.
8. Umxholo wothuthu ophantsi: Ekubeni imveliso ingena-ionic, ihlanjululwa ngempumelelo ngokuhlanjwa ngamanzi ashushu ngexesha lokulungiselela, ngoko ke umxholo wothuthu wayo uphantsi kakhulu.
9. Ukugcinwa kwemilo: Ekubeni isisombululo samanzi esixineneyo kakhulu semveliso sineempawu ezikhethekileyo ze-viscoelastic xa kuthelekiswa nezisombululo zamanzi zezinye iipolymers, ukongezwa kwaso kunamandla okuphucula imilo yeemveliso zeseramikhi ezikhutshiweyo.
10. Ukugcinwa kwamanzi: Ukuqina kwamanzi kwimveliso kunye nokuqina okuphezulu kwesisombululo sayo samanzi kuyenza ibe yiarhente yokugcina amanzi esebenzayo.

Ukupakisha kunye nokuthumela:
Ubunzima obupheleleyo obuyi-25 kg, ibhegi edityanisiweyo yephepha-plastiki, ingenziwa ngokwezifiso ngokweemfuno zabathengi.
Le mveliso ifunxa umswakama lula kwaye kufuneka igcinwe kwindawo epholileyo neyomileyo.
