In addition to marble furniture has a very high request for the consolidation and environmental protection of the sheet, there is also a strict control of the radioactivity of the stone. For a long time, people have mistakenly thought that marble furniture will have radiation, and it will inevitably cause some scruples when purchasing. In fact, natural marble has very low radioactivity and does not harm the human body at all. The highly radioactive materials are artificial marble furniture. So what are the hazards of artificial marble ? How to distinguish artificial marble? Let's take a look together. What are the hazards of artificial marble As the main raw material of artificial marble is petroleum derivatives, domestic oil prices continue to rise, making some manufacturers use inferior raw materials such as formaldehyde and benzene and other harmful substances in the manufacturing process in order to obtain greater profits. In addition, direct participation in organic solvents and the use of inferior inorganic pigments, which may contain heavy metals such as lead or cadmium, will lead to the quest for maximum benefit. In the current market, there are quite a few artificial stone slabs containing excessive amounts of harmful substances such as benzene, formaldehyde, lead, and organic acids. One common feature of this type of sheet is that it has a pungent chemical odor (especially if the odor is greater during processing. ), The color is unnatural chemical color, this type of artificial stone plate containing formaldehyde and benzene will produce a pungent atmosphere in the cutting process, after the plate consumes the processing and molding device, there will still remain excessive formaldehyde and benzene: formaldehyde and Benzene will discontinuously volatilize within 3-5 years. The volatilization of benzene and formaldehyde and exposure to heavy metals will directly contaminate the imported food. This harmful substance not only passes through the human respiratory system but also enters directly into the digestive system. And the speed is more pronounced. Therefore, it is particularly important to choose artificial stones with excellent quality. In the winter, especially in the north, the home blockade of air is not fluent and the indoor temperature is high, it will accelerate the volatilization of such “toxic plate†benzene and formaldehyde and other solvents, and harm the human body’s well-being. More serious! How to distinguish artificial marble Due to the fact that man-made stone contains chemical synthetic substances, some of the artificial stones produced by the poor quality are harmful to the human body, have a low hardness, are afraid of scratching, are afraid of hot, and are fearful of coloration. Therefore, we must carefully identify when purchasing, to avoid the purchase of low-quality production of artificial stone, here I give you six ways to identify the inferior artificial marble method, I hope useful to everyone, summarized as follows: A look: The visual color of the sample is not cloudy, there is no similar plastic gum texture on the outside, and there is no fine pore on the back of the plate. Two smells: The nose smells no pungent chemical breath. Three touch: Hand touch the appearance of the sample has a sense of silk, no astringent, no significant sense of up and down. Four strokes: The surface of the sheet was cut with a fingernail, and there was no obvious scratch. Five touch: The same two samples hit each other, not easily broken. Six checks: Check whether the product has ISO quality system certification, quality inspection report, there is no production quality insurance card and related security signs. What are some of the hazards associated with artificial marble and how artificial marble can be distinguished is briefly introduced here and I hope to help you.
