Recently, Zhejiang Online reported that Mr. Hangzhou’s Mr. Minh’s discomfort with formaldehyde caused by installing new homes was in dispute with the merchants. In the previous quarter-finals of the CBA playoffs, Liaoning defender Guo Ailun had a sudden high fever and had not scored one point. The reason is that the decoration leads to formaldehyde poisoning. After the inferior building materials and inferior building materials are gradually abandoned by the policies and markets, the rubber-containing coatings are coming from behind and become an important source of formaldehyde, which is very worthy of consumer attention.
As the “old puzzle” in decoration, the key reason why the formaldehyde problem has not been solved well is that the source is complex and it is difficult to eradicate. Wall surfaces, floors, furniture, doors and windows, carpets, and even unqualified curtains all have formaldehyde problems. Sources of formaldehyde Basically all point to the same thing - adhesives, these building materials, they can not be separated in the production or construction process.
In view of the problem of excess formaldehyde in adhesives, in recent years, the State has also issued many standards and policies such as “Limiting Standards for Volatile Organic Compounds in Architectural Coatings and Adhesives”. The formulation of companies’ production and decoration companies to restrict the volatile organic content of adhesives has been introduced. , reduce the harm of formaldehyde and other substances on health. The reporter observed that, nowadays, building materials with adhesive as the main source of formaldehyde, the emission of formaldehyde has been reduced, and the problem of excessive formaldehyde with plastic coatings is increasingly concerned.
At the end of 2017, it was easy to burst out with a number of newly furnished formaldehyde formaldehyde bursts for rented rooms. The person in charge feels that the suite with excessive formaldehyde exceeded the renovation and was newly renovated. It just brushed the wall and replaced some furniture. And electric appliances. The pungent smell, should come from the wall paint, new furniture. Because after the renovation, there is no good ventilation, so the smell of formaldehyde is relatively strong.
In an interview with reporters, experts in the industry's coating process said: 'The glue (adhesive) used in home improvement is an important source of indoor pollution, and the industry is more likely to say that there is no aldehyde or glue, in fact, furniture, wood flooring and other building materials. The wood is originally non-toxic, but most building materials are glued and glued. In order to fix the color of the sheet furniture, the ease of painting is also added to the paint.
According to Wei Renhua, secretary general of the China Petroleum Society's Coatings Coatings Committee of the Offshore Oil Industry Anti-corrosion Branch, adhesives are mainly used in furniture and paints. In the paints, traditional paints have been gradually damaged because they contain a lot of formaldehyde and are extremely harmful. Abandoned. However, in the market, interior wall paints are mixed, especially poor quality products. Once brushed, most of the indoor formaldehyde emissions will be exceeded.
Experts also pointed out that according to the national "indoor air quality standards", the safety of formaldehyde concentration is not more than 0.1mg/m3, but the human body must be 0.4mg/m3 and above the concentration can feel discomfort. Formaldehyde concentration in a certain space also With superimposed effect, a variety of products that do not exceed the standard can be used at the same time, it may still cause excessive indoor formaldehyde concentration, which requires consumers to pay special attention.
To avoid the hazards of paints containing plastics, we should try our best to choose water-based paints, and require businesses to show environmental certificates. Under the premise of conditions, professional formaldehyde removal can be performed after completion of renovations, and professional inspections will be carried out afterwards.
