Among many artificial stone products, quartz stone has stable structural performance and is environmentally friendly and recyclable. Its external temperament similar to natural stone and these superior internal properties make it a substitute for natural stone. Since the color and texture of natural stone are very limited, it is difficult to meet diversified needs, and quartz stone production technology is controllable, which can be adjusted to any color and texture, extending the fashion of the product.

As the application of quartz stone becomes more and more extensive, quartz stone manufacturers have developed rapidly, which also caused a certain confusion to the quartz stone market. The price difference of quartz stone is large, and the quality is uneven, causing some confusion to buyers. The quality of the 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 particles are evenly mixed. The quality of the vacuum press determines the density of the finished board, which also has a great relationship with the control of the personnel. The time of vacuuming and pressing also directly affects the density of the board. The reasonableness of the curing furnace determines the flatness of the blank. Polishing is the last process in the production of quartz stone plates and it is the most critical. The quality of the polishing equipment directly affects the brightness of the polished surface.

What standards should qualified quartz stone meet? The pressure of the quartz stone plate production press should reach more than 50 tons, and the density of the plate produced should reach 2.6g/cm3. The hardness must reach Mohs hardness level 6 or above, which is why the surface cannot be scratched with a sharp tool. Due to the high density of the board, the water absorption of the board itself is only 0.02%, which is almost zero. In addition, the quartz stone plate must have a certain bending ability, and the bending strength must be greater than 30Mpa so that the plate has a certain resistance to bursting.
