Precautions for artificial stone countertops

(1) Do not place high-temperature objects directly or for a long time on artificial stone countertops.
(2) Never use artificial stone countertops as cutting boards. Please place cutting boards on top when cutting vegetables.
(3) Try to keep the surface of artificial stone as dry as possible.
(4) Strictly prevent the contact of strong chemicals with the surface of artificial stone.
Attention to purchasing:
Traditional artificial stone countertops are usually made of acrylic resin and aluminum hydroxide, which have certain toughness and hardness, but are afraid of being scratched by knives. This material is corrosion-resistant, resistant to light, and can be used to create various shapes under high temperature conditions. The aging process is slow, and the product has a long lifespan. It has the advantages of being non-toxic, harmless, and does not change color. In addition, this type of countertop is easy to renovate, polish, and polish. But currently, counterfeit countertops on the market are not like that anymore. Due to the fact that calcium powder countertops are highly competitive products. A good artificial stone countertop costs several thousand yuan, while a poor quality countertop can be bought for a few hundred yuan, "experts said. Due to fierce competition and the pursuit of high profits, some manufacturers are willing to lower product quality. Originally, aluminum hydroxide should have been added to the resin, but due to the high cost of aluminum hydroxide, they added calcium powder, namely calcium carbonate, to the countertop. Due to the instability of calcium carbonate, it is very prone to chemical reactions when exposed to hot acids. A normal acrylic sheet should have a resin content of 35%. Only when the resin reaches a certain proportion can the sheet have good toughness. After adding calcium powder, the artificial stone board becomes fragile, prone to cracking and deformation, and prone to yellowing. When exposed to ultraviolet light, it turns yellow and is prone to discoloration. Soy sauce and other substances can seep in and contaminate the countertop. The lifespan of the countertop will be greatly reduced, seriously affecting the functionality of the cabinet. It is understood that the service life of the cabinet is about 10 years, and once the countertop is adulterated, the lifespan is only one or two years, greatly reducing the functionality of the cabinet.
According to relevant practitioners, consumers can also detect the authenticity of countertops through the following five methods.
At first glance, the sample color is clear and not turbid, with good transparency, no plastic like gum feeling on the surface, and no small pores on the back of the board;
Second touch: The surface of the sample feels silky, without any roughness or obvious unevenness when touched by hand. (This can distinguish whether aluminum hydroxide or calcium carbonate is used);
Three strokes: Use nails to scratch the surface of the board without obvious scratches;
Four tests: Soy sauce can be used to test the permeability of the countertop (the result is no permeability); Use vinegar to test for the addition of calcium carbonate (results show no color change and no powder); Use a lighter to burn the tabletop sample (the result is flame retardant, no open flame, and the tabletop with higher acrylic content has less odor);
Five checks: Check whether the product has ISO quality system certification, environmental label certification, quality inspection report, product quality assurance card and related anti-counterfeiting marks.
