What is the pollution of the building materials factory, and what are the disadvantages of the pollu

Building materials are common items in our decoration, but with the development of society and economy and our awareness of environmental protection, we are gradually concerned about the pollution of building materials products, the pollution of building materials to the living environment is not as shocking as the cracking of the wall or the tilt of the beams and columns, it is difficult for ordinary people to observe with the naked eye, the following is a detailed introduction to the pollution of building materials for you mainly as follows: Radioactive contamination: It has been determined that about 2%-3% of buildings have asbestos and radon in them, the radiation dose of radon in the room is 10 times more harmful than the X-ray examination.

Scientists have also found that if there is a radioactive gas radon in the room, if in the clean air, the short-lived radon nuclei hit the walls, carpets, doors, windows, and curtains, the radiation effect can be slowly weakened, and if the air is mixed with cigarette smoke, the radon nuclei will condense on the smoke particles, and the radioactive isotopes in the cigarette smoke will also increase the incidence of lung cancer in people. Nowadays, many building materials such as granite, marble, floor tiles and other ceramic building materials and cement contain some radioactive materials such as radon or cobalt to varying degrees. Volatile toxic gases from building materials:

Chemical fiber carpets laid in the living room, wooden furniture made of sawdust fiberboard, or foam materials, composite boards, etc., will slowly emit a small amount of formaldehyde gas, and formaldehyde and asbestos have been proven to be quite dangerous carcinogens. The other is benzene, a solvent that is often used in fuels, inks, paints, plastic products and rubber, which can make people dizzy, chest tightness, and even nosebleeds or asthma, and more than a certain concentration can also become a carcinogen. With the popularity of air conditioning in the home, indoor air circulation is not circulating, which makes the concentration of these volatile toxic gases greatly increased, becoming an invisible health killer.

The easiest way to eliminate pollution from building materials in the home is to place greenery. Scientists have found that green plants have a good purifying effect on polluted air in rooms and offices.

Over the course of several years, they tested the absorption capacity of dozens of different greens for dozens of chemical compounds, and shifted their focus to ornamental plants that could be purchased at any nursery, and found that the amount of greenery that was effective in lowering the chemicals in the air and converting them into their own nutrients was surprising.

Building materials are not only radioactively contaminated, but also volatile toxic gases, so factories can't avoid it

Modern homes generally decorate, buy fiber carpets, insulation, thermal insulation building materials and other materials continue to release a variety of toxic chemicals into the room, the most harmful of which is formaldehyde and radon pollution. Radon is produced by the metamorphosis of radium, a radioactive element found in building materials, tap water and coal gas. Radon has been linked to the onset of lung cancer.

The main means of prevention is indoor ventilation.

The range of building materials is wide.

1. Bricks and tiles: Burning bricks and tiles will produce nitrogen dioxide, nitric oxide, carbon monoxide, carbon dioxide, sulfur dioxide and other toxic and harmful substances. It also produces a lot of dust.

2. The manufacture of cement, lime, stone and ceramic tiles will produce toxic gases and toxic water.

3. Wood boards, etc.: formaldehyde, TVOC and other gases.

4. Coatings, etc.: produce toxic gases and harm human health.
