The traditional artificial stone countertop is usually made of acrylic resin and aluminum hydroxide, which has certain toughness and hardness, but it is afraid of knife scratches. This kind of material is corrosion-resistant and light-resistant, and can be made into various shapes under high temperature conditions. The aging process is very slow. The artificial stone countertop has a long life and has the advantages of non-toxic, harmless, and non-discoloring. In addition, this type of countertop is easy to refurbish, polish and polish.

But this is not the case with counterfeit countertops on the current market. Because calcium powder countertops are the product of fierce competition. "A good artificial stone countertop costs a few thousand yuan, while inferior countertops can be bought for a few hundred yuan." According to experts, due to fierce competition, in order to pursue high profits, some manufacturers will not hesitate to reduce the quality of their products, which should have been added to resin. Aluminum hydroxide, but because of the high cost of aluminum hydroxide, they add calcium powder, that is, calcium carbonate, to the countertop. Because calcium carbonate is not stable enough, it is very prone to chemical reactions when encountering hot acid. Normal acrylic board, the resin content inside should reach 35%, only the resin reaches a certain proportion, the board will have better toughness. After adding calcium powder, the artificial stone board becomes fragile, easy to crack and deform, and easy to turn yellow. "Ultraviolet rays will turn yellow as soon as it is irradiated, and it is easy to eat. Soy sauce and other things will seep into the countertop." "The life of the artificial stone countertop will be greatly reduced, which will seriously affect the function of the cabinet." It is understood that the life cycle of the cabinet is approximately. In 10 years, once the countertop is adulterated, the life span is only one or two years, which greatly reduces the function of the cabinet.
According to relevant practitioners, consumers can also detect the authenticity of the countertop in the following five ways.
Take a look: the color of the artificial stone countertop sample is pure and not turbid, with good permeability, no plastic-like texture on the surface, and no small pores on the back of the plate;
Second touch: The surface of the artificial stone countertop sample has a silky feel, no astringency, and no obvious unevenness. (This can identify whether aluminum hydroxide or calcium carbonate is used);
Three strokes: scratch the surface of the board with a nail without obvious scratches;
Four tests: Soy sauce can be used to test the permeability of the countertop (the result is no penetration); the vinegar can be used to test whether calcium carbonate is added (the result is no color and no powder); the countertop sample can be burned with a lighter (the result is flame retardant, no open flame) , The higher the acrylic content, the less tasteless the countertop);
Five checks: check whether the artificial stone countertop product has ISO quality system certification, environmental protection mark certification, quality inspection report, product warranty card and related anti-counterfeiting marks.
