The the concentration of cement foaming agent is generally high, so it needs to be diluted with a certain proportion of water to form a foaming liquid. Then the foaming liquid is made into foam. Pour water and foaming agents into a water tank to fully dissolve them and observe the blisters. The prepared cement is poured into a cylinder, then fully stirred by a stirring tool, and sent into a wallboard machine through a high-pressure conveying pipe or manually processed into a finished product.

Ceramic powder This is a heterogeneous, composite material made of metals or alloys and one or many ceramic phases. Ceramic phase of cermets usually contains high melting point oxides (Al2O3,ZrO3, BeO3, MgO etc.). ), nitrides (TiN, BN, Si3N4, etc. ), carbides (TiC, WC, etc. ), borides (TiB2, ZrB2, etc.) The main components of the metal phase are Ti, Cr. Ni, Co., Fe and any other metals. They can also be metal materials like bronze alloys or high-temperature alloys. Cermets are classified acc
CuO could also be a good candidate in solar energy conversion due to many properties: high absorption coefficient, narrow bandgap in the visible region, which is expected to give high conversion efficiency, being nontoxic, stable, good electrical conductance, simple manufacturing process, and so on. A more direct way to convert solar energy to electricity is to use CuO as an absorber in solar cells. The efficiency of solar cells based on CuO is far lower than that of leading chalcogenide systems
