How does Redispersible Polymer Powder reduce the risk of tile hollowing?

As the size of the tiles increases, hollowing is more and more likely to occur after laying, and even the accident of the tiles falling off occurs. This problem has a lot to do with the flexibility of the bonding material.

The ceramic tile has high density and low deformation, and the base layer will have a large deformation due to various external and own factors. The tile adhesive as an adhesive layer must be able to absorb the stresses caused by deformation. If the tile adhesive does not contain glue powder, or the content of vae rdp powder is low, it will be difficult to absorb the stress caused by deformation, so that the entire paving system will gradually fall off at the weak point, forming an empty drum.

Redispersible Polymer Powder can provide tile adhesive with the ability to adapt to stress and deformation, that is, improve the flexibility of tile adhesive. In this system, the rigidity of the tile adhesive is mainly provided by inorganic materials such as cement and sand, and the flexibility is provided by the glue powder. The polymer is interspersed in the pores of the cement stone to form a polymer network, which becomes the elastic link between the rigid components, making it flexible. When deformation occurs, the polymer network absorbs the stress, ensuring that the rigid components are not cracked or damaged.

Therefore, improving the flexibility of the bonding material is very important to reduce hollowing. Appropriate amount of glue powder can improve the state of the network structure formed by the polymer inside the tile glue.
