How to Identify Artificial Marble and Natural Marble?

There is a simpler way to distinguish between artificial and natural marble: drop a few drops of dilute hydrochloric acid, the natural marble will foam violently, while the artificial marble will foam weakly to no foaming.

Advantages and disadvantages of natural marble

Advantages of natural marble:
1. Natural marble has compact structure, good compressive strength, natural texture, thick texture, majestic and majestic, very small linear expansion coefficient, good rigidity, high hardness, strong wear resistance, small temperature deformation, and easy and simple maintenance. Long service life, non-magnetization, no stagnation, not affected by humidity, good plane weighing.
2. The stone structure is dense and the compressive strength is high.
3. Good decoration. Stone has natural texture, thick texture, solemn and majestic artistic effect
4. After long-term natural aging, the rock has a uniform structure, a very small linear expansion coefficient, and the internal stress completely disappears without deformation.
5. Good rigidity, high hardness, strong wear resistance, small temperature deformation.
6. It is not easy to stick to dust, easy to maintain and maintain, and has a long service life, which can reach more than a hundred years.
7. No magnetization, it can move smoothly during measurement, without any sense of stagnation, and is not affected by humidity, and the plane is well-balanced.

Disadvantages of natural marble:
1. Naturally generated, so there is color difference:
2. It is too hard and not elastic enough to make a table that exceeds 1 meter. It is easy to break when heated or hit, and it is difficult to repair, and it is not easy to process smooth shapes; 3. There are natural pores and are easy to be polluted, so it is harmful to the use environment. have higher requirements;
4. During the splicing operation, because the artificial glue color cannot match the natural stone, and its cross-section is uneven, seam splicing is allowed.
5. Natural marble is radioactive. Qualified natural marble has strict control over the radioactivity of the stone, and basically will not cause harm to the human body.

The hazards of inferior artificial marble are currently in the market. Some artificial stone slabs contain excessive amounts of harmful substances such as benzene, formaldehyde, lead, and organic acids. A common feature of these slabs is that they have a pungent chemical odor (especially during processing. This kind of inferior artificial stone plate containing formaldehyde and benzene will emit a pungent smell during cutting, and excess formaldehyde and benzene will still remain after the plate is produced, processed and shaped Benzene, formaldehyde and benzene will volatilize discontinuously within 3-5 years. The volatilization of benzene and formaldehyde and the exposure to heavy metals will directly pollute imported food. This harmful substance not only passes through the human respiratory system but also directly Entering the digestive system, the degree and speed of poisoning are more significant.

Therefore, it is particularly important to choose high-quality artificial stone. In winter, especially in the north, the closed air at home is not smooth, and the indoor temperature is high, which will accelerate the volatilization of solvents such as benzene and formaldehyde, which are harmful to human body, and damage human health. more severe!

How to distinguish the advantages and disadvantages of artificial marble?

The method of distinguishing inferior artificial marble is hoped to be useful to everyone, as follows:
1. Look: Visually, the color of the sample is pure and not turbid, there is no plastic-like texture on the surface, and there is no small air hole on the back of the board.
2. Smell: The nose smells no pungent chemical smell
3. Touch: The surface of the sample has a silky feel, no astringency, and no obvious unevenness when touched by hand
4. Scratch: Use your nails to scratch the surface of the board without obvious scratches
5. Collision: The same two samples are knocked against each other, not easy to break
6. Check: Check whether the product has ISO quality system certification, quality inspection report, product quality assurance card and related anti-counterfeiting marks.
