Embodiment 1
[0017] The process steps for making matt board, matt board, pitted board or concave-convex board are: (1) intercept and process the granite or marble substrate with working plane; (2) immerse the granite or marble substrate in the acid solution for a period of time Finally, take it out, wash it with water, and neutralize it with dilute alkali to get the finished product. The quartz on the slate surface is a convex point, and the feldspar is a concave point, and the mica will not be corroded, so the shimmering bright spot effect of the mica sheet can be presented on the surface of the slate (see figure 1 ).
[0018] The above-mentioned granite or marble substrate is cut out according to the required specifications after the granite or marble is sliced, ground or polished
[0019] The above-mentioned acid solution is 1-10% hydrofluoric acid aqueous solution.
[0020] The above-mentioned granite adopts all the granite marbles in the world. The above-mentioned granite adopts pe...

[0022] Concave-convex art patterns can be made on granite or marble substrates. The process steps are as follows: (1) Paste the plastic self-adhesive film on the working plane of granite or marble substrates. There are two situations when pasting: ① Make a convex art pattern: remove the part other than the required art pattern on the plastic self-adhesive film and paste it on the work plane; ② Make a concave art pattern: press the embodied art pattern on the plastic self-adhesive film After the pattern is hollowed out, paste it on the working plane; (2) Immerse the above-mentioned stone plate in the pre-prepared acid solution for a period of time, take it out, wash it with clean water, and remove the plastic self-adhesive film after neutralizing it with dilute alkali, that is Convex or concave art patterns can be made on granite or marble substrates.

[0026] For surface treatment on the pearl white granite slab, first cut and process the pearl white granite base material with a working plane, that is, slice, smooth or polish the pearl white granite base material and cut it according to the required specifications. After immersing the plate in the prepared acid solution for a period of time, take it out and wash it with clean water. Since the acid solution corrodes the first feldspar on the slate faster, and the quartz is slower to corrode, but the mica is not corroded, so it can appear on the surface of the slate. Concave-convex pits, in which the a feldspar is a concave point, and the quartz is a convex point. At the same time, the shimmering bright spot effect of mica flakes can also be presented on the slate.
