Title: NON-SINTERED FILLED VACUUM STONE AND PREPARATION PROCESS
Abstract:
A non-sintered filled vacuum stone and a preparation process. The vacuum stone comprises particle aggregates having different particle sizes and a filling unit body having a standard volume; the filling unit body is prepared from a solid particle filler having a fine particle size and a liquid filler; the surface of the solid particle filler is provided with a flexible liquid-filled film formed by filling the liquid filler; the particle aggregates having different particle sizes are filled with and attached to each other; a gap between the particle aggregates is filled with the filling unit body to from a vacuum enclosure. According to the vacuum stone, small and large particles are filled with each other so that all the gaps are fully filled and air in the gaps among the particle aggregates are expelled to form the vacuum enclosure, i.e., the vacuum stone is formed by using the principle of Magdeburg hemispheres.
