Nowadays, marble is more and more frequent in the application of home decoration, but little friends do not have much knowledge of this type of stone. For example, marble is divided into natural marble and artificial marble, and some marbles are harmful to humans. What are the hazards of marble ? Today, Ou Yifeng Furniture Xiaobian will introduce you to the hazards of marble. Let's take a look!
Marble hazards
Characteristics: Natural marble is metamorphic rock formed by the original rock in the earth's crust through the high temperature and high pressure in the earth's crust. Its texture is fine and solid. After polishing, it is like a mirror. The texture is more stretched and beautiful than granite. Compressive strength is high, according to the different rock formations, up to 300MPa, and water absorption is small, with no wear and deformation characteristics.
Hazard: Some experts have found that the main hazard of natural marble is the radioactive material in stone, which is a characteristic that many stone materials will have. There are two kinds of radioactivity of natural marble. One is that it will cause damage to the body's hematopoietic system, nervous system, etc. after direct exposure to the human body; the other is radioactive trait paralysis, which is emitted into the air and is inhaled by the human body. Will increase the chance of lung cancer. Although marble contains radioactive substances, in fact, natural marble has low radioactivity, and it will not cause any harm to humans. The high-activity radioactive materials are artificial marble furniture.
Artificial marble hazards
Features: With the development of modern architecture, the requirements for lightweight, high-strength, aesthetic, and variety are put forward for decorative materials. Artificial facing stone appears in this situation. It has light weight, high strength, corrosion resistance, pollution resistance, convenient construction, and artificial control of patterns.
Hazard: Because artificial marble is manufactured by humans, some manufacturers use inferior materials in the manufacturing process in order to reduce costs, apply harmful substances such as formaldehyde and benzene, and some even directly add organic solvents, and use inferior heavy metal materials. A large number of "toxic marbles" have been manufactured, and the damage caused by artificial marble is mainly manifested in the pollution caused by inferior materials. This type of plate generally has a common pungent chemical odor. The color is not natural enough and it will cause great harm to the human body. Formaldehyde and benzene will volatilize for a long time in the future, and then enter the human body. It causes great harm to the human body. At the same time, besides harming the body, the inferior artificial marble has relatively own characteristics, such as small hardness, fear of scratching and fear of coloration.
Black marble hazards
Features: Black marble is a color of marble. There are many varieties of marble, black Guilin black alone there is the danger of black marble; Hunan Shaoyang black marble; Shandong Cangshan Moyu, King Venus; Henan Anyang Mo Yuhei. Black marble is also a relatively expensive stone. Most of the colors on the market are dyed black marble.
Hazard: Black marble is also natural and artificial. Natural black marble, like natural marble, contains radioactive materials, but its radioactivity is very low, and it will not affect humans. Artificial marble is the one that affects the human body. Some of the unscrupulous manufacturers violated the national regulations and used materials containing carcinogenic substances to dye marble, which caused the human body to be affected.
The impact of natural marble on the human body is basically negligible, but artificial marble damage to the human body depends on whether the manufacturer has processed according to national standards. There is no problem with the natural black marble itself, and there are problems with the artificially manufactured black marble.
Therefore, when consumers purchase, they must pay attention to two issues:
Whether marble is natural or not, there is no identification certificate or it is a certificate issued by the country;
Did artificial marble pass the national inspection eligibility criteria and obtain certification from relevant authorities? Do not be fooled by cheap money and endanger the health of your family and yourself.
The above is a detailed introduction to the hazards of marble and I hope to help you.
