Everyone is familiar with quartz stone. It is one of the most ideal countertop materials and the most widely used material in countertop. Quartz stone is composed of quartz sand and cullet as the main filler (the silica content reaches 99.9%). The unsaturated resin is added and stirred for high pressure and high vibration molding.

Since the quartz content in the plate is as high as 93% or more

It is separated from the artificial stone product by quartz stone manufacturers as quartz stone. The surface of quartz stone is smooth, smooth and free scratch-resistant, dense and non-porous, colorful and colorful. The structure is anti-corrosion and anti-fouling like glass. The finished shape is as perfect as artificial stone. The advantages of quartz stone compared to other materials are: wear resistance, scratch resistance, high temperature resistance, penetration resistance, no color difference, etc.

What are the main differences in the quality of quartz stone?

The same quartz stone slab, but the quality has a big difference. The quality of the quartz stone raw materials will directly affect the quality of the slab. The main filler quartz sand is divided into several grades, and the price is also several times different. In addition, the proportion of raw materials, if the quartz sand content in the plate is less than 90%, it will directly affect its hardness.

The most important reason to affect the quality of sheet metal is the production equipment. At present, the production process of quartz stone is mainly based on die casting, and the tonnage of the press is the key to quality of the sheet. In the production of quartz stone, the force per square must be greater than 60 tons (the negative pressure must be greater than 98 under vacuum conditions), and the density of the plate must reach 2.6 g/cm3.

China’s small quartz worktops stone factory has many households, and the pressure tonnage of small manufacturers is not up to this requirement. The production equipment they use may be early obsolete equipment, mainly to quickly occupy the market with low quartz stone prices. For those who have a long-term management of the quartz stone industry, they can only be distinguished by looking at the appearance of the brand plate. Even if the appearance is not visible, in the processing of the plate, you can feel it when you open the material.

So how should our end users distinguish?

In fact, the difference in the quality of quartz stone plates is mainly the hardness of the plates. We can use irons such as keys and fruit knives to scratch the surface of the plates. If a white scratch appears, it is unacceptable because the white scratch is a powder of the blade material. If the black scratch is qualified, because the hardness of quartz is second only to diamond, its hardness is higher than that of iron, and the black scratch is the color of iron.
