First, to see whether there is porosity in the cross-section of the product. If any, the texture of the product is loose and the density cannot reach ≥ 2.40 g/cm3. It cannot be used on the ground, especially on the ground with high traffic.
Second, with the eyes to observe whether the product surface sand pit and cracks, if any, then the product density does not meet the requirements.
Third, the polishing degree of qualified products is generally between 79 and 90, because 95% of the internal structure of artificial marble is natural marble powder, so the polishing degree is higher. The inferior product has a high resin content, generally more than 15%, so the surface looks old and dull.
Fourth, the compressive strength of qualified products is generally 6500 PSI -13000 PSI, bending strength between 1150 PSI -2300 PSI. Poor products do not meet this standard because they contain too much resin. The most direct method of identification is to use a lighter to burn, and it is a poor quality product that smells bad.
In addition, it can be identified by other methods such as water soaking, ink leakage and physical impact. Consumers are advised to exercise caution when purchasing artificial marble.
