Difference between quartz stone and granite

A: The difference between quartz stone and granite:

1. Quartz stone is made of 93% quartz and 7% resin, and the hardness reaches 7 degrees, while the granite is synthesized from marble powder and resin, so the hardness is generally 4-6 degrees, which is simply quartz Stone is harder than granite, scratch-resistant and wear-resistant.

2. Quartz stone can be reused. Because the internal material of quartz stone is evenly distributed, the front and back sides are basically the same. That is to say, after the surface is severely impacted and damaged, the front and back sides pass After simple polishing and sanding, the same effect as the original front can be achieved, which greatly reduces maintenance costs and costs. The granite cannot be reused, because its positive effect is specially made, and once it is damaged, it cannot be used again. Simply put, quartz stone is not easy to break, while granite is easy to break.

3. Due to the characteristics of its own material, quartz stone determines its high temperature resistance. The temperature below 300 degrees Celsius will not have any influence on it, that is, it will not deform and break; because it contains a large amount of resin, it is It is particularly prone to deformation and scorching at high temperatures.

4. Quartz stone is a non-radiation product and has no adverse effects on the body; the raw materials we make quartz stone are non-radiation quartz; and the granite is made of natural marble powder, so there may be radiation, which may cause adverse effects on the body.

 5. When looking at the sample, there is a protective film on the surface of the stone. The surface of the quartz stone does not need any processing.

B: 　The real pressure injection quartz stone (thousands of tons of pressing + vacuum method) is essentially different from small workshop casting (directly poured into the mold) quartz stone:

There are two types of quartz stone: pouring and pressure injection. Generally, it is difficult to distinguish between the two types of quartz stones on the market. In terms of hardness, injection molding has high hardness and compactness, which is better than pouring. But our country currently does not have a mature injection technology. There will be many quality problems in the future. The casting hardness is much lower than that of injection molding.

When buying, you can take the key to scratch the surface to see if there are any scratches, then check the brightness of the surface, and see if there are pores on the back of the sheet. There is also the issue of thickness.

Then there is the problem of penetration. The pores of the quartz stone produced by thousands of tons of pressing + vacuum method are all filled with resin, and the quartz stone produced by this process is not easy to crack.
