Mortelklass HPMC

Mortelmassa HPMC kan användas som en cellulosaeterblandning i murbruk och kan användas i nästan alla murbruksprodukter, främst på grund av dess vattenretention. Generellt sett är vattenretentionen av HPMC av mortelgrad relaterad till dess viskositet, substitutionsgrad och partikelstorlek.

Mortelklass HPMC has many functions in mortar. The main function of Mortelklass HPMC in cement mortar is water retention and thickening.




In addition, due to the interaction between Mortelklass HPMC and cement system, it will also play an auxiliary role in entraining air, retarding setting, and improving tensile bonding strength.

In Mortelklass HPMC, the introduction of methoxy groups reduces the surface energy of the aqueous solution containing Mortelklass HPMC, so that Mortelklass HPMC has an air-entraining effect on cement mortar. Introduce appropriate air bubbles into the mortar. Due to the "ball effect" of air bubbles,

Detta kan förbättra murbrukens konstruktion, och samtidigt ökar införandet av bubblor murbrukens utgångshastighet. Naturligtvis måste mängden blöda luft kontrolleras, och för mycket blöda luft kommer att ha en negativ inverkan på murbrukens styrka.



Mortelklass HPMC will delay the setting process of cement, thereby slowing down the setting and hardening process of cement, and prolonging the opening time of mortar. However, this effect is disadvantageous to mortar in colder areas.

Mortelklass HPMC is a long-chain polymer material. After being added to the cement system, it can improve the bonding performance with the substrate under the premise of fully maintaining the moisture of the slurry.

In summary, the performance of Mortelklass HPMC in mortar mainly includes: water retention, thickening, prolonging setting time, air-entraining and improving tensile bonding strength.
