1. When observing the surface finish of horizon group quartz slab products, it is found that the place with particles is bright, but the powder is not bright. The powdery part is not bright, which is caused by the low hardness of the quartz powder. Therefore, improving the hardness of quartz powder is an effective way to improve the hardness and finish of the plate. After many tests and applications, it is found that adding 10% of 100-mesh flat glass powder to 325-mesh quartz powder can increase the Mohs hardness of the plate by 0.5 and improve the surface finish by 3-5o.

2. The watermark problem of fine-grained quartz plate is a difficult problem to be solved in the production of quartz plate. Generally, manufacturers start from improving the mixing effect of the mixer, and add a pulverizer before the cloth to solve the problem. It will get a certain effect, but it cannot be eradicated. After careful research, the so-called watermark problem, in addition to the problem of the formula, is actually caused by the different densities of the whole surface of the plate, that is, the pressure and vibration force on the whole plate during pressing are different. The solution is to increase the rigidity of the indenter.

3. Increase the variety of colors on the surface of horizon group quartz slab products, and expand the application range of quartz slabs. The surfaces of the resulting quartz stone slabs are now flat. With the development of decoration, it is required to make the surface natural, which requires the application of a new process.
