There are two kinds of marble on the market, one is natural marble and the other is artificial marble. For these two types of marble, many consumers have a question about what kind of marble they want to choose. Where is the difference between artificial marble and natural marble ? Which one is better? Next, Xiao Bian answered for everyone.
The difference between artificial marble and natural marble
I. Comparison of advantages and disadvantages of natural marble and artificial marble
1 , natural marble
Advantages: natural pattern, good feel after polishing, strong hardness, much wear resistance compared to man-made, fear of coloring, pores, penetration
Disadvantages: Partial radiation, natural stone brittleness, poor flatness, love fracture, marble and marble connection is very obvious, can not be seamless splicing, easy to breed bacteria, lack of elasticity, difficult to repair, rapid temperature changes will occur rupture.
2 , artificial marble
Advantages: No radiation, various colors, a certain degree of flexibility relative to the natural, the connection between marble and marble is not obvious, the overall feeling is strong!
Disadvantages: chemical synthetic materials are harmful to the human body, have low hardness, are afraid of scratching, are afraid of hot, and are afraid of coloring.
Second, the harm of inferior artificial marble
In the current market, there are locally appropriate artificial stone slabs containing excessive amounts of harmful substances such as benzene, formaldehyde, lead, and organic acids. One common feature of these types of plates is that they have a pungent chemical odor (especially if the odor is greater during processing. ), The color is not natural chemical color, this type of artificial stone plate containing formaldehyde and benzene will produce a pungent odor 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. Volatilization of benzene and formaldehyde and exposure to heavy metals will directly contaminate 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, the selection of artificial stone with excellent quality is particularly important. In the winter, especially in the north, the home is not fluent in the air, the indoor temperature is high, it will accelerate the volatilization of such “toxic†benzene and formaldehyde and other solvents, and harm the body's well-being. More severe!
Third, comparing the hazards of natural marble and artificial marble
1 , the hazards of natural marble
In fact, for marble, there are mainly artificial marble and natural marble. Artificial marble may have some hazards. So what about natural marble? The hazards of natural marble are not the same as those of artificial marble. According to expert analysis, natural marble is also a hazard. This hazard mainly comes from the volatilization of radioactive elements in natural marble. The radioactive hazards in natural stone are mainly in two aspects: In vivo radiation and in vitro radiation.
2. Hazard of Artificial Marble
For the hazards of artificial marble, the hazards of natural marble are not the same as the hazards of artificial marble. Experts have not concluded that all artificial marble is hazardous. According to experts' suggestions, the hazard of artificial marble is mainly reflected in the pollution caused by inferior materials. on. Artificial marble is made from the day after tomorrow, so it has a lot of uncontrollable elements. In order to reduce costs, some manufacturers use inferior materials in the manufacturing process, resulting in some toxic substances.
How to distinguish inferior marble
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.
The above is an introduction to the differences between artificial marble and natural marble. I hope to help you. For more knowledge about marble, please continue to pay attention to information on this site.
