Does artificial marble have radiation?

Artificial marble contains radiation.

At present, the marble commonly used by people on the market is divided into two types: natural and artificial. Since marble, granite, gypsum and other materials in nature contain the natural radioactive element radium, artificial marble is also made of natural marble or granite gravel as filler. Therefore, when used as building materials for interior decoration, the radioactive gas radon and its progeny produced by the decay of radium elements will produce radiation. Radon has been listed as one of 19 carcinogens by the World Health Organization and listed by the International Agency for Research on Cancer. The main carcinogens entering the room.

Currently, studies have shown that indoor radon concentrations in my country have shown an increasing trend. The use of marble in home decoration should be minimized, and the radioactive radon concentration of marble should be tested before decoration. You can also reduce the indoor radioactive radon concentration by replacing low-radioactive stone materials, frequently opening windows for ventilation, and using air purifiers and negative ion generators.

In addition, in addition to being radioactive, the adhesives used in artificial marble can also produce harmful gases such as formaldehyde and benzene. Therefore, when buying marble, you should pay attention to the following points:

First, go to a regular merchant to buy, especially artificial marble, and the manufacturer must issue a relevant test report;

Second, When identifying natural and artificial marble, you can add a few drops of dilute hydrochloric acid. Natural marble has violent foaming, while artificial marble has weak or even no foaming;

The third is to identify the quality of marble. You can tap it lightly with your hands. The marble with a loose structure will have a low and mute sound, while the high-quality marble will have a crisp sound when knocked.

Extended information

Traditional artificial marble countertops are usually made of acrylic resin and aluminum hydroxide, which have a certain degree of toughness and hardness, but are afraid of being scratched by knives. This kind of material is resistant to corrosion and light, and can be made into various shapes under high temperature conditions. The aging process is very slow, the product has a long life, and it has the advantages of being non-toxic, harmless and not discolored.

In addition, this kind of countertop is easy to renovate, sand and polish. But this is not the case with the counterfeit countertops currently on the market. Because calcium powder countertops are a product of fierce competition. "A good artificial stone countertop costs several thousand yuan, while a low-quality countertop can be purchased for a few hundred yuan." Experts said that due to fierce competition, in order to pursue high profits, some manufacturers do not hesitate to reduce product quality. It should be added to the resin. Aluminum hydroxide, but because the cost of aluminum hydroxide is high, they add calcium powder, that is, calcium carbonate, to the countertop.

Because calcium carbonate is not stable enough, it is very prone to chemical reactions when encountering hot acid. The resin content of a normal acrylic board should reach 35%. Only when the resin reaches a certain proportion can the board have better toughness. After adding calcium powder, the artificial stone slab becomes fragile, easily cracked, deformed, and prone to yellowing. "Ultraviolet light will turn yellow when exposed to it, and it is easy to eat color. Soy sauce and other things will seep in and pollute the countertop." "The life of the countertop will be greatly reduced, seriously affecting the function of the cabinet."

It is understood that, The service life of cabinets is about 10 years. Once the countertop is adulterated, its lifespan is only one or two years, which greatly reduces the functionality of the cabinets.
