Κονίαμα βαθμού HPMC

Κονίαμα βαθμού HPMC

Κονίαμα βαθμού HPMC plays a very important role in mortar.

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

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

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

Αυτό μπορεί να βελτιώσει την κατασκευαστική απόδοση του κονιάματος, και ταυτόχρονα, η εισαγωγή φυσαλίδων αυξάνει το ρυθμό παραγωγής του κονιάματος. Φυσικά, η ποσότητα του αέρα εξαέρωσης πρέπει να ελεγχθεί και ο υπερβολικός αέρας θα έχει αρνητικό αντίκτυπο στην αντοχή του κονιάματος.

Κονίαμα βαθμού 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.

Κονίαμα βαθμού 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 Κονίαμα βαθμού HPMC in mortar mainly includes: water retention, thickening, prolonging setting time, air-entraining and improving tensile bonding strength.
