whats the funcation of hpmc in mortar
The first is the bonding and thickening effect of hpmc. When we apply cement mortar, we are very optimistic about its bonding performance. What should we do if the compressive strength of cement mortar is insufficient? Add hpmc, the effect of hpmc is that it has bonding, Water retention, improving compressive strength and other functions. It can improve engineering construction, high water retention, and anti-sag work ability. That way, work efficiency is improved. The other is thickening. Adding hpmc can increase the compressive strength and flexural strength of cement mortar. Reasonable improvement of the surface coating, increase the adhesion, and enhance the adhesive compressive strength of the mortar, which can also be better for engineering construction.
The second is good reliability, which is also very important. The use of raw materials containing hpmc can improve reliability and will not be harmed by the pH value. Such products have stronger quality and are not prone to problems. The third is the water retention performance of hpmc. Everyone who uses putty powder for interior walls understands that the water retention performance of the putty powder is very important. Otherwise, after the construction of the project, the water retention performance is too poor, which will easily cause the wall to crack and eventually shed skin. The base cellulose can reasonably retain water, bond and moisturize in the putty powder. The surface troweling performance improves uniformity. Prevent the film from taking off the situation and so on.
Ultimately it is its dispersion. Except for interior wall putty powder and cement mortar, it has the effect of a colloidal solution protective film in the production of anti-corrosion coatings, which can reasonably avoid the condensation of aggregated particles. In addition, tile adhesive as a tile adhesive and adhesive can further improve the construction performance of the adhesive
