1) The anti-pollution ability of the rock slab must meet the requirements. When we go to buy rock slabs, we can wipe some oil stains on the rock slabs. If the oil stains are wiped off easily, it means that the rock slabs have a strong anti-pollution ability.
The wear resistance should be good.
The heat resistance is better. We can use fire to burn. If there is no change in the rock slab, it means that it has excellent heat resistance, with good impact resistance.
