Application of redispersible latex powder in tile adhesive
by admin on 21-03-04
As early as the 1930s, polymer binders were used to improve the performance of mortars. After the successful launch of polymer emulsions on the market, WACKER developed a spray drying process to provide emulsions in the form of rubber powder. The beginning of the era of dry-mix mortar. For more ...
Analyze what factors will affect the water retention of plaster plaster
by admin on 21-02-21
The water retention rate of plastering gypsum slurry is related to the content of water-retaining agent, retarder and water ratio. Increasing the amount of water-retaining agent can increase the water retention rate, delay the setting time, and have a retarding effect, but it affects the strength...
