In building materials, the addition amount of HPMC is very low, only 0.1%-1%, but it plays an irreplaceable role and can significantly improve the water retention, fluidity and lubricity of building materials.

Wall putty in construction system
The coating system is generally divided into three layers: wall, putty and paint. When the ambient temperature and humidity change, due to the different deformation coefficients of the three-layer materials, the deformation is consistent, which inevitably generates stress in the decoration system. The putty resists cracking of the substrate and peeling of the film by virtue of its flexibility to relieve stress. At the same time putty provides a leveling, smooth or textured substrate for latex paints. Due to the optimization of the putty formula, the amount of latex paint is reduced and the service life of the coating film is prolonged.
Gypsum VS Cement
Gypsum plays a very important role in the building materials industry. Compared to cement, gypsum has unique characteristics:
- Fast curing speed and adjustable curing time;
- There is a little swelling after hydration, and the cementitious material has no hollowing and cracking phenomenon;
- After curing, a large number of porous structures are formed in the material, which has the functions of ventilation, sound absorption and sound insulation. It can adjust the humidity of living and working places and create a comfortable climate, so gypsum plays an important role in interior decoration;
- Rich in natural gypsum resources, unit energy consumption is lower than cement. Gypsum can be recycled;
- Power plant desulfurization produces a large amount of gypsum, providing a rich source of gypsum.
