In the dry and highly quartz stone which is good
Scratch: use wallpaper knife to cut on any surface to see if wallpaper knife is obviously changed, and whether there is no obvious scratch or no scratch on quartz stone surface.Board thickness: qualified quartz stone surface thickness should be uniform, the error is not more than 2 millimeters.Trachoma: dense, fine quartz without obvious pores or trachoma.Resistance to pollution: generally qualified quartz stone, at least water droplets in its surface will form water droplets, not direct penetration, stain resistance, artificial stone markers can be rubbed up, dry wipe can be.Some quartz stone do a strong impact, steel ball landing more than a meter, will not lead to fragmentation.Some weathering quartz stone is very strong on the outside, exposed to the weather for more than a month is intact.
Some people because of high temperature? Some people because good-looking? The reasons are different. I'm here to say briefly about the characteristics of the qualified quartz stone and the skills of quality identification.High temperature resistance: To observe whether the shape changes with the lighter barbecue, premise of good eye protection, since there may be cracked, the test objective of this part is to know quartz stone will not be lit, fire performance.
In fact, the selection of quartz stone do not be too blind to follow the brand, because each brand under the product quality is different, the direct comparison is not comparable. It doesn't make sense to use a brand of high-end products and other brands of low-end products.
