Problems solved by technology

[0004] 1. Heating and heating during production requires energy consumption, and the waste discharged will also pollute the environment;
[0005] 2. The chemical composition of the glue after heating is unstable, and it is easy to chemically react with cement, lime calcium, gypsum, etc., and it is difficult to ensure the effective quality of raw materials;
[0006] 3. Most of the traditional glue needs to be mixed with cooked rubber powder for construction, and strive to criticize the dust, but it will make the wall easy to mold after use
