[0003] This kind of inorganic foaming material adopts the insulation board formed after the above-mentioned pouring, foaming, coagulation and solidification production process. Due to the characteristics of natural foaming that cannot be accurately controlled, it leads to defects such as uneven upper surface and poor thickness precision of the product; in addition , although this kind of inorganic foam board has good thermal insulation due to its low density, the strength of this porous and loose structure is also poor. During handling and construction, it is easy to lose slag on the surface or even crack as a whole. Easy to crush and sink, which in turn leads to poor workability of the product

Embodiment Construction
[0020] The present invention will be described in further detail below through a specific embodiment, so as to help understand the content of the present invention.
[0021] like figure 1 As shown, a metal or non-metallic mesh 3 or non-woven fabric is laid on the bottom of the flat mold consisting of a flat bottom plate 1 and a rectangular mold frame 2. The mold frame and the flat bottom plate are of a split structure, so as to facilitate Remove its frame.
[0022] like figure 2 As shown, apply a layer of inorganic slurry 4 without foaming agent on the bottom of the flat mold, and level it with a brush or trowel. The slurry 4 should be soaked through the metal or non-metal mesh 3 to form a dense structure with mesh 3. The protective layer. The inorganic slurry may have the same composition as the foaming material but does not contain a foaming agent, or may be an inorganic slurry having a different composition from the subsequent foaming material.

The invention discloses a production method for an inorganic foaming board, comprising the steps of pouring and foaming in a flat die. After the foaming process is finished and a material has no flowability, the material is pressed from the upper surface to the required thickness by using a flat clamp, and then a curing process is carried out. The production method for the inorganic foaming insulation board is characterized in that the material is pressed by using the flat clamp when the material has no flowability after the foaming is finished and before curing is carried out, so that the upper surface of the material is flat, and the thickness is guaranteed to be even and precise. In addition, a compact layer is formed on the upper surface after the material is pressed, the strength and the hardness of the surface of the material are enhanced, and fracture resistance, slag falling resistance and resistance to pressure are improved.
Description
technical field [0001] The invention belongs to the field of building materials, in particular to a production method of an inorganic foam board. Background technique [0002] Inorganic foamed boards include foamed cement boards made by foaming cement and fly ash, foamed gypsum boards, and inorganic foamed gelled perlite boards. The production process is through casting in the mold, foaming, Condensation and curing. [0003] This kind of inorganic foaming material adopts the insulation board formed after the above-mentioned pouring, foaming, coagulation and solidification production process. Due to the characteristics of natural foaming that cannot be accurately controlled, it leads to defects such as uneven upper surface and poor thickness precision of the product; in addition , although this kind of inorganic foam board has good thermal insulation due to its low density, the strength of this porous and loose structure is also poor. During handling and construction, it is ...
