Waterproof coating causes bathroom "poisoning"

Water repellent treatment is a necessary procedure in bathroom renovation. However, some homes found that after the renovation of the bathroom smell is relatively large, the test found that it was actually the pollution caused by the waterproof coating.

In this regard, experts advise consumers that the pollution of waterproof coatings can not be underestimated, and once the pollution is produced, it is not easy to remove.

The reporter found that the brand of waterproof material on the market is diverse and varied. A waterproof material store staff told reporters, "If you say that the waterproof coating poisoning, may be used a poor quality polyurethane waterproof coating. Now on the market polyurethane waterproof coating, is the use of asphalt instead of coal tar as raw material. But in using this Coatings are generally diluted with organic solvents such as toluene and xylene and are therefore toxic.

The odor-resistant waterproof paint is highly toxic. The worker explained that the tar-free polyurethane waterproof material is environmentally friendly and consumers can choose to use it. “The odor-resistant waterproof paint is highly toxic and will volatilize carcinogens such as benzopyrene for a long period of time. It must not be used for indoor waterproofing. Before buying it, be sure to smell it with your nose and if there is a strong irritating odor.”

There are still market data for the eliminated products. As of now, China has 1,400 waterproof material production enterprises with production licenses, and there are more than 500 companies without licenses. Due to the unregulated management of the home improvement market, some inferior products are still "active" in the market. Industry sources told reporters that some informal home improvement companies, or guerrillas decorated on the side of the road, often use low-quality inferior materials for short-term interests. This has led many consumers to bring back pollution without their knowledge. Family.

Such materials are generally made from coal tar or raw materials containing some coal tar. Oil and gas have a pungent odor and excessive inhalation of tar oil and gas in the short term can poison it. At present, this product has been designated as a phase-out building decoration material by the relevant national authorities.

The indoor floors treated with these waterproof coatings can meet the requirements of indoor environmental protection.” In addition, consumers At the time of purchase, it should go to the reputable building materials market and choose a qualified company for construction.

If the waterproof coating contains toxicity, it will become an "invisible killer" in the home. Therefore, when selecting materials, it is necessary to kill this "invisible killer".

He said that there are more homes to warm the floor than in previous years. “Some newly renovated homes are There is no way to live in the ground, because the smell is too heavy."

There is formaldehyde in the glue.” Gu Gong explains, “The boiling point of formaldehyde is 19.5°C, and the temperature of floor heating is often at 20°C. Above, the floor is baked at this temperature for a long time, and the formaldehyde inside will be released in large quantities after reaching the boiling point."

In the indoor air testing of many homes that have been warmly installed, Gu Gong found that once the floor is warmed, the amount of formaldehyde detected is much higher than when it is not available.

When choosing floor heating, try to pick solid wood floors that are branded or floor-heated.

In addition, it is also advisable to open the floor a few times after the floor is laid and before the stay. Each time you open for a day or two, let the formaldehyde be released as much as possible.

"Especially dark fabrics and fabrics that have been specially treated with anti-wrinkle and softness have greater formaldehyde content."

“However, the formaldehyde content of household items is not terrible, as long as its limited range is within the range that the human body can afford.” Experts said that it is necessary to watch out for the use of non-formal manufacturers in the market that have not used high-temperature forming and disinfection. Recycled fibers made from leftovers produce inferior curtains and mattresses.
