Artificial stone countertop identification method

A check: First check whether the artificial stone products have quality system certification, anti-counterfeiting marks, quality inspection reports, etc.
Two strokes: Use your nails to scratch the surface of the board, whether there are obvious scratches, and judge its hardness.
Three checks: Visually inspect the product for its pure color, no plastic-like texture on the surface, and whether there are pores on the front of the board.
Four touches: touch the surface of the sample without astringency, silky feeling, no obvious uneven feeling, and the interface is smooth.
Five smells: There is no pungent chemical smell in the nose.
Six touches: The same two samples are knocked against each other, which is not easy to break.
Seven burns: Take a slender strip of artificial stone and burn it on the fire. The artificial stone of poor quality is easy to burn, and it burns very vigorously. The artificial stone of good quality cannot be burned unless it is added with a combustion aid. and it will automatically turn off.
Eight throwing: look at its hardness and strength, take a piece of material, the size of 200*200 is enough, throw it hard on the concrete floor, the artificial stone of poor quality will be broken into many small pieces, and the good quality will be broken at most Into two or three pieces, and if the force is not enough, it can bounce off the ground.
