Recently, Zhejiang Online reported that Mr. Hangzhou’s public servant was poisoned by formaldehyde poisoning due to the installation of a new house, and there was a dispute with the merchant. In the previous quarter-finals of the CBA playoffs, Liaoning defender Guo Ailun suddenly had a high fever, and one point was not obtained. The reason was that the decoration caused formaldehyde poisoning. After building materials such as inferior adhesives and inferior plates are gradually abandoned by policies and markets, gel-containing coatings are emerging as an important source of formaldehyde, which is worthy of consumer attention.
As an "old problem" in decoration, the key reason why the problem of formaldehyde has not been solved well is that the source is complicated and difficult to eradicate. There are formaldehyde problems in walls, floors, furniture, doors and windows, carpets, and even unqualified curtains. The source of formaldehyde basically points to the same thing - adhesives, these building materials, which are inseparable from production or construction.
In response to the problem of excessive formaldehyde in adhesives, in recent years, the state has also issued many standards and policies such as the "Conditional Standards for Volatile Organic Compounds in Architectural Coatings and Adhesives". By setting the corresponding standards for production and decoration companies, the content of volatile organic compounds in adhesives is limited. To reduce the health hazards of substances such as formaldehyde. The reporter observed that the emission of formaldehyde in building materials with adhesive as the main source of formaldehyde has been reduced, and the problem of excessive formaldehyde in rubber-containing coatings is receiving increasing attention.
At the end of 2017, it was free to explode the formaldehyde explosion table of several newly renovated rental houses. The responsible person believes that the suite with excessive formaldehyde has been refurbished after receiving the house, just brushed the wall and replaced some furniture and electrical appliances. The pungent smell should come from wall paint and new furniture. Since the decoration was not carried out, there was no good ventilation, so the formaldehyde smell was strong.
In the interview with reporters, the paint technology experts in the industry said: “The rubber (adhesive) used in home decoration is an important source of indoor pollution. The industry has the saying that “there is no aldehyde and no glueâ€. In fact, furniture, wood flooring and other building materials The wood is originally non-toxic, but most of the building materials are glued with glue. The coloring and coating of the plate furniture will add glue to the paint in order to fix the color and increase the convenience of painting."
Wei Renhua, secretary general of the Offshore Oil Industry Anticorrosion Branch of the Coatings and Coatings Committee of the Chinese Chemical Society, also said that adhesives are mainly used in furniture and coatings. In the case of paint, traditional paints have been abandoned by the market because they contain a lot of formaldehyde and are extremely harmful. However, in the market, interior wall paints are mixed, especially for products of inferior quality. Once painted, most of them will cause excessive formaldehyde emission in the room.
Experts also pointed out that according to the national "indoor air quality standards", the safe formaldehyde concentration is not more than 0.1mg/m3, while the human body needs 0.4mg/m3 and above to feel discomfort. The concentration of formaldehyde in a certain space also has a superimposed effect. A variety of products that do not exceed the standard are used at the same time, and it is still possible to cause indoor formaldehyde concentration to exceed the standard, which requires special attention of consumers.
To avoid the hazards of rubber-containing coatings, water-based coatings should be selected as much as possible, and businesses are required to produce environmental certificates. Under the premise of conditional conditions, professional formaldehyde removal can be carried out after the decoration, and professional inspection is carried out before check-in.
