Among many artificial stone products, quartz stone structure performance is stable, green and environmentally friendly, and can be recycled. It is similar to the external temperament of natural stone and these superior intrinsic properties, making it a substitute for natural stone. Due to the limited color and texture of natural stone, it is difficult to meet the diversified needs, and the quartz stone making technology can be controlled, and can be blended into any color and texture, which extends the fashion of the product.
With the wider application of quartz stone, quartz stone manufacturers have been able to develop rapidly, which also caused some confusion in the quartz stone market. The price difference of quartz stone is large and the quality is uneven, which causes certain confusion to the purchaser. The quality of quartz stone plate is not only limited to the purchase of raw materials, but also has an inseparable relationship with the production equipment and process. For example, mixing and mixing is the main reason for determining the color difference. The quality of the mixer determines whether the particle mixing is uniform. The quality of the vacuum press determines the density of the board, which is also related to the handling of the personnel. The vacuum and pressing time also directly affect the density of the board. The rationality of the curing oven determines the flatness of the blank. Polishing is the last step in the production of quartz stone sheets and is the most critical. The quality of the polishing equipment directly affects the brightness of the polished surface.
What are the criteria for qualified quartz stone? The pressure of the quartz stone plate production press should reach 50 tons or more, and the density of the produced plates should reach 2.6 g/cm3. Hardness should reach Mohs hardness of 6 or higher, which is why it is impossible to scratch the surface with a sharp sharpener. Due to the high density of the sheet, the water absorption of the sheet itself is only 0.02% almost zero. In addition, the quartz stone plate should have a certain bending ability, and the bending strength should be greater than 30Mpa so that the plate has a certain resistance to bursting.
