Advantages of natural marble stone: The pattern is formed naturally, it feels good after polishing, has strong hardness, and is not afraid of coloring, large pores, and permeable compared to artificial wear.
Disadvantages: There is a part of radiation, natural marble stone is brittle, and the connection part of the easily broken marble and the marble with poor flatness is obvious. It cannot be seamless, it is easy to breed bacteria, lacks flexibility, is difficult to repair, and breaks quickly. The temperature changes.
The advantages of artificial marble: no radiation, artificial marble with a wide range of colors, complete varieties, a certain degree of flexibility compared with natural, unobvious joints, and a strong sense of integrity!
Disadvantages: Harmful parts of synthetic materials, low hardness, not resistant to scratches, fear of burning, fear of coloring.
How to distinguish between an artificial marble and a natural marble stone
There is also a simpler way to identify artificial marble and natural marble stone: drop a few drops of dilute hydrochloric acid, natural marble stone foams violently, artificial marble foams weakly or even does not foam.
The hazards of inferior artificial marble
Currently on the market, there are some artificial stones that are commensurate with excessive benzene, formaldehyde, lead, organic acids and other harmful substances. This kind of board has a common feature, which is the pungent chemical odor (especially large in the processing process). Odor), the color is not natural chemical color, which includes the pungent smell of formaldehyde and benzene during the cutting process. Inferior artificial stone plates. After the sheet metal forms the processing capacity of the device, there is still excess benzaldehyde: formaldehyde and benzene Will be 3-five years of discontinuous volatilization period, volatile benzene and formaldehyde contact with heavy metal pollution will directly import food, which is through the respiratory system and direct access to the digestive system, poisoning speed and more obvious levels not only harmful substances.
Therefore, it is particularly important to choose artificial stone with excellent teaching quality management. In winter, especially in the north, homes are closed because the air is not smooth and the indoor temperature is high. It will accelerate the volatile solvents and "poisonous" such as benzene and formaldehyde. , Used to damage human well-being is more serious!
The methods of identifying some inferior artificial marbles are hoped to be useful for everyone. The general analysis is as follows:
Take a look: The color of the sample is pure but not turbid, the appearance is not similar to plastic colloid, and the back of the board has no small pores. Second smell: Is there any pungent chemical smell? Three touches: touch the sample to have a silky appearance without astringency, and does not significantly improve the unevenness of the upper and lower surfaces. Four stroke: the appearance of the nail plate without scratches. Five touches: the same two pieces of samples are knocked against each other, and it is not easy to break.
