39 results about "Ground stone" patented technology

In archaeology, ground stone is a category of stone tool formed by the grinding of a coarse-grained tool stone, either purposely or incidentally. Ground stone tools are usually made of basalt, rhyolite, granite, or other cryptocrystalline and igneous stones whose coarse structure makes them ideal for grinding other materials, including plants and other stones.

Construction method for crystallizing of sandstone ground stone materials

The invention discloses a construction method for crystallizing of sandstone ground stone materials. The construction method comprises the steps that (1) white cement is smeared on the bottom faces ofthe sandstone stone materials, the sandstone stone materials are laid on the ground, and a gap between every two adjacent sandstone stone materials is 3-5 mm; (2) protective agents are smeared on thesurfaces of the sandstone stone materials, after the protective agents are absorbed by the sandstone stone materials, waterproof films are laid on the surfaces of the sandstone stone materials in a covering mode, and natural air drying is conducted for at least 10 days; (3) hollowing positions of the sandstone stone materials are subjected to potting treatment; (4) the edges of the sandstone stone materials are cut, and thus the gap between every two adjacent sandstone stone materials is 3-5 mm; and (5) the gap between every two adjacent sandstone stone materials is subjected to caulking treatment through marble glue. The surfaces of the sandstone stone materials are delicate, bright and free from pollution, warping deformation of the sandstone stone materials is avoided, the service lifeof the sandstone stone materials is prolonged, and the overall attractive effect of the sandstone ground stone materials is guaranteed.

Non-woven fabric grinding block for stone polishing and manufacturing method of non-woven fabric grinding block

The invention discloses a non-woven fabric grinding block for stone polishing and a manufacturing method of the non-woven fabric grinding block. The non-woven fabric grinding block comprises the following components in percentage by weight: 20-30% of non-woven fabric fiber, 15-30% of grinding material, 5-15% of filler, 20-35% of resin adhesive, 0-5% of wax and 0-5% of pigment. The characteristic that a hard material is used as a grinding tool in the prior art is changed, relatively soft non-woven fabric fibers and soft resin are selected as carriers of the grinding material, proper softness is controlled by utilizing a three-dimensional structure of the non-woven fabric, the grinding tool is well attached to the surface of the stone in the grinding and polishing process, hard collision scratches are avoided, and shadows and scratches are not likely to be generated. In addition, the grinding material held by the resin also has a certain grinding effect, so that the polished and ground stone surface is finer and smoother, and the glossiness is higher. And the board surface is beautiful and bright. The polishing agent is used for polishing stones, and the glossiness can be improved by 5-20 degrees after the polishing agent is arranged behind a magnesia abrasive block or an oxalic acid composite abrasive block.
