The sitting room tea table marble panels have radiation? How to choose and buy high quality marble coffee table?

marble tea table will have radiation, everyone will think when buying will inevitably some worry, in fact, natural marble of radioactive is low, basic won't cause harm to human body. In recent years, the marble is widely used in furniture production, but there is a lot of bad fake marble furniture on the market at present, these so-called inferior marble furniture not only contains a lot of radioactive elements, to bring so much harm the health of consumers. Marble radiation refers to the radiation dose rate greater than zero. 23 mu Sv/h range, the damage to human body. Marble radiation dose rate at 0. 23 mu Sv/h range, radiation is greater than this value is on the high side, below this value, can be neglected.

the state on the application of the stone has a strict standard of classification, and production and processing unit is strictly in accordance with the standards of classification processing, and stone the radioactive decay of radon gas mainly through internal radiation cause person damage, (of the international commission on radiological defense ICRP) Is the internal irradiation ammonia concentration shall not be higher than the standard prescribed by the Bp / 100 square meters, according to the security will be divided into four categories, namely A, B, C, and greater than C:

A class, is not higher than 70 Bp ( If, in accordance with the quality of the mobile phone absorption is much smaller than words, mobile phone is 1 w/KG) Is applicable to any place.

B class, no higher than 90 bq in addition to the indoor, can apply anywhere.

C, do not apply to the construction and the outdoor environment, metope, roads, etc.

more than class C, above 100 Bp above applies only to dam, seawall, bridge pier is used.

tell from the radiation, the radiation of natural marble is very low, and basically what poses a harm to human body, and is larger than the natural marble, artificial marble radiation will have certain harm to human body, so nine JuWang remind friends are home to buy marble table, marble coffee table price to put aside, it is important to first take a look at its radiation levels, does great harm to human body. This is very critical.

marble table usually when processing to the stone material of radioactive, usually after processing of the tea table of radioactive standard, basic will not harm the human body. But some inferior even fake marble coffee table on the market, in addition to the performance difference, also contains excessive amounts of radioactive elements, when the choose and buy must identify carefully, lest affect health.

: strict standard of our country in the world standard. Stone is mainly radon radioactive substances in the radon gas is heavier than air, general heavy on the ground, if under the condition of ventilation, oxygen will be diluted, lack of oxygen concentration, never constitutive wei harm to human body; If poor indoor and ventilated condition, a person to 24 hours in the indoor lasted for half a year, to hurt, once a person walk, radon gas will be solved. Therefore, stone of the radioactive harm to human body, is almost a little feeble, marble is a kind of zero radioactivity can be called 'green', it is the most ideal home decor stone.

2, how to choose and buy marble coffee table?

1, the concept of lines, each piece of natural marble should have the natural grain of unique design, lack of change and inferior marble furniture surface, abrasive grain.

2, see the color, the color of natural marble natural, fluent, beautiful. Inferior marble furniture is cheap white marble into other color of marble, and the color most of these products is not the natural color of marble, look stiff and rigid.

3, flashlight, inferior marble is gravel for the filling material, in cement, gypsum and not saturated polyester resin as adhesive, classics agitate is made after forming, grinding and polishing. Cut torch light opaque surface exposure without burnish, is made of high quality marble, marble furniture in giessen torch light beams penetrate directly, high surface gloss.

4, drops of hydrochloric acid, high grade marble drops of hydrochloric acid can produce a large number of chemical reaction, severe foaming, because natural marble raw material contains a lot of calcium. In contrast, inferior marble because its itself is by focusing on synthesis of resin, cement, all of the chemical reaction is not strong or even no bubbles.
