Chemical bonding mechanism of glass fiber cloth:

This action mechanism is that the bonding effect is formed between the bonding mortar and the face brick through the van der Waals force between molecules or the chemical bond between the reactive functional groups.

When the water absorption rate of face brick is small, the sintering degree is good, and the porosity is low, the role of its physical mechanical anchoring mechanism is weakened. For the pure cement bonded mortar that mainly relies on physical mechanical anchoring, the bonding strength of the face brick is not high; For the polymer modified tile bonding mortar, because of the van der Waals force formed between the functional groups on the polymer molecular chain and the molecules of the tile surface material or the new valence bond combination between some functional groups, this polymer mortar can form a firm bond to even the smooth tile surface.
