The original marble is the marbled white limestone of Dali, because its surface can naturally form a variety of patterns, such as landscape painting, these natural marble is not much harm, but now, marble has become a general term , Refers to all the colored patterns of limestone for construction, but also because of this, resulting in the production of various types of marble frequently quality problems, especially some work not refined products, although the price is more convenient, more dangerous Big.
1, the dangers of natural marble
Natural marble, as the name implies, is naturally formed in nature, marble, stone is not good is containing radioactive material. Some experts have found that there are mainly two kinds of radioactive hazards of natural marble: one is the radionuclide and its daughters, which are formed by the decay of radioactive radiation in the air. This substance enters the human respiratory system causing radiation damage, inducing lung cancer, but also affect the human nervous system, lethargic, drowsy. Another is that the stone in the radiation directly to the human body produces a biological effect, the body's blood-forming organs, nervous system, reproductive system and digestive system damage.
Although marble contains radioactive substances, the material emitted by marble is very small and hardly affects the human body. Therefore, we do not have to worry too much about it.
2, the characteristics of artificial marble
Artificial marble is usually made of natural marble or granite crushed stone for the filler, with cement, gypsum and unsaturated polyester resin as a binder, after molding by mixing, grinding and polishing made, so artificial marble has many natural marble The characteristics of artificial marble, such as artificial adjustment, so many different colors, good flexibility, convergence is not obvious, the overall sense of very strong and colorful, with a ceramic luster, the appearance of high hardness, not easy to damage, corrosion resistance, High temperature, and very easy to clean. But there is also a big disadvantage, the more significant damage to the human body. Artificial marble commonly available on the market currently has the following four: Mud artificial marble, polyester artificial marble, synthetic artificial marble, sintered artificial marble.
3, artificial marble damage
Because man-made marble is made from artificial, it has many uncontrollable elements, some manufacturers in order to reduce costs, the use of inferior materials in the manufacturing process, the application of formaldehyde, benzene and other harmful substances, and some even directly added to the organic solvent , The use of heavy metals, poor quality materials, to create a large number of "toxic marble", and artificial marble damage is mainly manifested in the pollution caused by inferior materials.
Such boards generally have a common characteristic, pungent chemical odor, color is not natural, it will cause great harm to the human body, formaldehyde and benzene will be volatile in the future for a long period of time, and then enter The human body, causing great harm to the human body, while inferior artificial marble in addition to hurt the body, its own characteristics are relatively biased, such as hardness, fear of scratches, afraid of coloring.
In order to avoid the harm caused by marble, it is best to choose the best quality marble. So how to choose high-quality artificial marble it?
First, the eyes look: General good quality artificial marble, the surface color is relatively pure, small back holes will not appear on the plate.
Second, the nose smell: poor quality artificial marble will have a clear pungent chemical odor, but the quality will not.
Third, the hand touch: high-quality artificial marble surface will have a very clear sense of silk, and the surface is very smooth, two inferior is not.
Fourth, nails planning: I believe many people have tried this method, which is indeed a more effective method, high-quality artificial marble, with a nails plan, there will be no obvious scratches.
Fifth, each tapping: you can choose the two lines of marble, people knock on each other, if it is easy to break, then it is inferior, if not, to prove that the quality is better.
Sixth, check certificate: a product, we must first check whether it has ISO quality system certification, quality inspection reports, etc., which can be the first step to prevent their being cheated.
