Artificial marble is made of unsaturated polyester resin as the binder, natural marble or calcite, dolomite, silica sand, glass powder, and other inorganic powder, as well as an appropriate amount of flame retardant, color, etc., through mixing ingredients, porcelain casting, vibration compression, extrusion and other methods of molding and curing. Artificial marble is developed according to the problems in the actual use of natural stone materials. It has made great progress in moistureproof, acidproof, high-temperature resistance, and patchwork.
Of course, man-made things naturally have man-made shortcomings. Artificial stone is obviously not natural enough, and its texture is relatively fake, so it is often used in places with high practical requirements, such as cabinets, and in some harsh environments, such as kitchens and bathrooms; The window sill, ground, and other places that emphasize decoration are less used.
Because the production process of artificial marble varies greatly, and its performance and characteristics are not completely consistent, the advantages mentioned above are not necessarily the performance of artificial marble purchased by users. What are the differences between artificial marble and natural marble?
1、 Natural marble
Advantages: natural patterns, the good hand feels after polishing, strong hardness, more wear-resistant than artificial, not afraid of coloring, pores, and penetration.
Disadvantages: the natural marble is brittle, has poor flatness, and is easy to break. The connection between marble and marble is very obvious, and can not be seamlessly spliced. It is easy to breed bacteria, has insufficient elasticity, and is difficult to repair. The rapid change in temperature will cause cracks.
2、 Artificial marble
Advantages: various designs and colors, relatively natural flexibility, the indistinct connection between marble and marble, and strong overall feeling!
Disadvantages: some of the chemical synthetic substances are harmful to the human body, with small hardness, fear of scratching, scalding, and coloring
3、 How to distinguish artificial marble from natural marble
There is a simpler way to distinguish artificial and natural marble: drop a few drops of dilute hydrochloric acid, natural marble will blister violently, and artificial marble will not have a big reaction. Stone workshop stone5A
4、 The Harm of Inferior Artificial Marble
At present, there are quite a few man-made stone slabs on the market, which contain excessive amounts of benzene, formaldehyde, lead, organic acids, and other harmful substances. The common feature of such slabs is that they have a pungent chemical odor. This low-quality man-made stone slab containing formaldehyde and benzene will give off a pungent smell when cutting and processing. After the plate is consumed by the processing and molding device, there will still be excessive amounts of formaldehyde and benzene left: formaldehyde and benzene will volatilize discontinuously within 3-5 years, The volatilization of benzene and formaldehyde and exposure to heavy metals will directly pollute imported food. This harmful substance can not only pass through the human respiratory system but also directly enter the digestive system, with a more significant toxicity level and speed.
Therefore, it is particularly important to select high-quality artificial stone In winter, especially in the north, the air is not fluent when the house is closed, and the indoor temperature is high, which will accelerate the volatilization of solvents such as benzene and formaldehyde, which will cause more serious damage to human health!
5、 The methods to identify inferior artificial marble are as follows:
First look: the color of the visual sample is pure without turbidity, the appearance has no similar plastic colloid feeling, and the back of the plate has no small pores.
Second smell: no pungent chemical smell.
Third touch: feel the appearance of the sample with your hand, with a sense of silk, without astringency, and without obvious unevenness.
Four scratches: scratch the surface of the board with your nails without obvious scratches.
Five impacts: the same two samples are not easy to be broken by knocking each other.
Six checks: check whether the products have ISO quality system certification, quality inspection report, production quality assurance card, and relevant anti-counterfeiting marks.
