How to distinguish the pros and cons of marble made by others? What are the hazards of low-quality artificial marble?


One look: the color of the sample is pure and not turbid, the appearance is not similar to the plastic texture, and the back of the plate has no small pores.


Second smell: No pungent chemical smell in the nose.


Three touches: The surface of the sample touched by hand has a silky feel, no astringency, and no obvious up and down unevenness.


Four strokes: Use your fingernails to scratch the surface of the board without obvious scratches.


Five touches: The same two pieces of samples are knocked against each other, which is not easy to break.


Six checks: check whether the product has ISO quality system certification, quality inspection report, production quality assurance card and related anti-counterfeiting marks.


The hazards of low-quality artificial marble:


At present, in the market, some artificial slates contain excessive amounts of benzene, formaldehyde, lead, organic acids and other harmful substances. One common feature of this type of slabs is the pungent chemical odor (especially when the odor is greater during processing). ), the color is unnatural chemical color. This inferior artificial stone board containing formaldehyde and benzene will emit a pungent odor during cutting. After the board is consumed and processed by the forming device, there will still be excess formaldehyde and benzene: formaldehyde and Benzene will volatilize discontinuously within 3-5 years. The volatilization of benzene and formaldehyde and exposure to heavy metals will directly pollute imported food. This harmful substance not only passes through the human respiratory system but also directly enters the digestive system. The level of toxicity is And the speed is more significant.


Therefore, it is particularly important to choose high-quality artificial stone. In winter, especially in the north, it is not fluent to close the air at home, and the indoor temperature is higher, which will accelerate the volatilization of such "poisonous board" benzene and formaldehyde and other solvents, and cause more severe damage to human health!
