Taiwan Changchun PVA BP26 Granule For Building Mortar
The application of PVA Resin Changchun Brand in cement mainly lies in improving material properties, enhancing adhesion and durability. The specific functions and application scenarios are as follows:
1.Improving crack resistance and bond strength
During the hardening process of cement, PVA forms a flexible membrane structure, which disperses internal stress and inhibits the formation of micro-cracks, significantly enhancing crack resistance. At the same time, it can enhance the bond strength between the mortar and the substrate, and is suitable for applications such as tile adhesives and flexible adhesives. 1
2.Enhance water resistance and durability
PVA Resin Changchun Brand improves the microstructure of cement-based materials, enhancing their water resistance and prolonging the service life of the materials. For instance, adding 0.9% - 1.2% of PVA fibers can increase the crack resistance of concrete by 40% - 60% and the impact strength by 2 - 3 times. 1
3. As a cement additive
PVA Resin Changchun Brand can be used as a cement additive to improve the fluidity and durability of concrete. Its aqueous solution has strong adhesion to cellulose materials (such as paper, wood), and is suitable for use as a cement additive, re-wetting adhesive, etc.
