Foamed cement insulation board production process

1. Feeding and mixing: adding quantitative cement, foaming agent and stabilizing foam enhancer to the mixer through the feeding system, dry mixing for 30 seconds;

2, stirring: adding quantitative warm water to the mixer, wet stirring for 2 minutes; adding a quantitative blowing agent to the mixer for 8-15 seconds;

3, injection molding, foaming: immediately after the slurry is injected into the mold for foaming, the foaming process is about 3-5 minutes;

4. Initial maintenance: After the injection molding is completed, it is allowed to stand for several hours for initial maintenance;

5, demoulding: the foaming cement insulation board is initially set, and it can be demoulded when it has initial strength;

6. Cutting: The foamed cement insulation board with a certain strength can be cut after demoulding, and the cutting specifications can be adjusted according to the needs;

7, finished product maintenance: foaming cement insulation board curing age should be no less than 7 days.
