Method for distinguishing the quality of quartz slices

Quartz slice has strong high temperature resistance, low coefficient of thermal expansion, good chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, ultraviolet transmission spectrum performance, visible light transmission and near-infrared spectrum performance, and has higher mechanical properties than ordinary glass. Therefore, it is one of the indispensable excellent materials in modern cutting-edge technologies such as space technology, atomic energy industry, national defense equipment, automation systems, as well as industries such as semiconductors, metallurgy, chemical engineering, electric light sources, communication, light industry, building materials, etc. So how to distinguish the quality of quartz slices?

1. It smells very natural with a stone odor. During the production process of quartz stone with a residual odor, formaldehyde containing glue is added, and good quartz pieces are produced using environmentally friendly materials. The boards produced have a strong formaldehyde smell, and this type of quartz chip cannot be chosen even if it is sold at a low price, it is dangerous to life!

2. If there are pores, is there any porosity on the surface of the poor quartz sheet.

3. Obvious gaps in products and splices are considered good.

4. The scratches are deep and clearly unqualified, with a key or pencil sharpener.

5. Slightly falling stone powder is considered unqualified and sanded with less than 200 mesh.

6. Those with incisions and cracks are considered unqualified, with the upper and lower edges of the incision surface.
