Analysis of two production methods of foamed cement insulation board

Foamed cement can be divided into physical foaming and chemical foaming according to different production methods.

First, physical foaming

The foaming agent is prepared into a foam by mechanical equipment, and the foam is added to a slurry made of cement-based cementing material, aggregate, admixture, admixture and water, and is mixed, stirred, cast and cured. Insulation board (hereinafter referred to as foamed cement insulation board).

Second, chemical foaming

The foaming agent is added to the slurry made of the cement-based cementing material, the aggregate, the admixture, the admixture and the water, and is mixed and stirred to make the inside of the slurry by chemical reaction in the mold. An insulating plate that is closed and vented and cured.
