What are the hazards of artificial marble

　　 The original marble refers to the white limestone with black patterns in Dali, because its surface can naturally form various patterns, such as landscape paintings, etc. These natural marbles are not very harmful, but now, marble has become A general term that refers to all kinds of limestone used in construction with color patterns. Because of this, quality problems frequently occur in the production of various types of marble, especially some products that are not exquisite in workmanship, although the price is relatively convenient. The harm is even greater.

　　1. The hazards of natural marble

　　Natural marble, as its name implies, is marble formed naturally in nature. Stone is not good. It contains radioactive substances. Some experts have discovered that there are two main radioactive hazards of natural marble: one is the radioactive substance radon and its daughters formed by the decay of radioactive radiation in the air. This substance enters the human respiratory system and causes radiation damage and induces lung cancer. At the same time, it also affects the human nervous system, making people feel depressed and drowsy. The other is that the radiant body in the stone produces a biological effect after directly irradiating the human body, which will damage the blood-forming organs, nervous system, reproductive system and digestive system in the human body.

　　Although marble contains radioactive substances, the emissions of marble are very small and basically have no response to the human body, so you don’t need to worry too much.

　　2, the characteristics of artificial marble

　　Artificial marble is usually made of natural marble or granite crushed stone as the filler, with cement, gypsum and unsaturated polyester resin as the adhesive It is made by mixing, forming, grinding and polishing, so artificial marble has many characteristics of natural marble. For example, artificial marble can be adjusted manually, so it has a variety of colors, good flexibility, unobvious connection treatment, and a very strong overall feeling. , And colorful, with ceramic luster, high surface hardness, not easy to damage, corrosion resistance, high temperature resistance, and very easy to clean. But there is also a big shortcoming, which can cause significant harm to the human body. At present, there are generally four kinds of artificial marbles commonly used in the market: clay artificial marble, polyester artificial marble, composite artificial marble, and sintered artificial marble.

　　3. Artificial marble damage

　　Because the artificial marble is made by man, it has many uncontrollable In order to reduce costs, some manufacturers use inferior materials in the manufacturing process to apply harmful substances such as formaldehyde and benzene. Some even directly add organic solvents and use heavy metal inferior materials to produce a large number of 'toxic marbles.' The damage of artificial marble is also mainly manifested in the pollution caused by inferior materials.

　　 This type of board generally has a common feature, it has a pungent chemical smell, and the color is not natural enough. It will cause great harm to the human body. Formaldehyde and benzene will be in the future for a long time. It volatilizes within a period of time and then enters the human body, causing great harm to the human body. At the same time, inferior artificial marble in addition to harm the body, its own characteristics are also relatively deviated, such as low hardness, fear of scratches, fear of coloring.

　　 Then how to reduce the harm of marble?

　　 When buying stone, be sure to figure out the radioactivity and harmful gas indicators of the stone, and keep indoor ventilation when using it. Only open windows for ventilation to reduce hazards. Placing some plants is also helpful for fresh air. Please pay attention to choosing suitable indoor plants, such as:

　　Aloe: Aloe has a certain effect of absorbing peculiar smell, and it also has the effect of beautifying the room;

　　Aloe Vera: p>

　　 Cactus, Ling arrow lotus, Fairy finger: When the TV or computer is turned on in the room, the negative oxygen ions will decrease rapidly. The stomata on the fleshy stems of these plants are closed during the day and opened at night. While absorbing carbon dioxide, they release oxygen, which increases the concentration of negative ions in the indoor air;
