In recent years, the concept of “green home improvement†is gradually accepted by the public. However, due to the superimposed effect of pollutants caused by the large amount of building materials used in the decoration process, even if people completely adopt green building materials, indoor air pollution cannot be completely eliminated.
A year ago, in order to create a green home, Mr. Zhang carefully selected a variety of green building materials during the decoration, from paint to adhesive, from floor to flexible packaging, all pay attention to the environmental protection of the product, and they are all selected with green The product identified. However, when it was painstakingly completed the entire renovation, the report of an air quality testing company made him disappointed - there are still many pollutants in the room.
It sounds incredible: the complete use of green building materials can not prevent decoration pollution, which makes many consumers puzzled. Insiders pointed out that this is the misunderstanding of people's understanding of "green home improvement." Wang Fang, secretary-general of Shanghai Indoor Environmental Purification Association, told reporters that the pollutants in the decoration process will have a superposition effect. For example, a piece of plate of one square meter will not release excessive pollutant gas, but a bookcase made of several square meters of the plate will be used. It is possible to release excessive pollutant gases.
In addition, there are many problems in the green building materials on the market. “There are too many types, so that even people in the industry are unclear. The certification mark is too complicated, and it may also be adulterated.â€
A survey conducted by the Shanghai Indoor Environmental Purification Industry Association showed that more than half of the newly renovated air quality in Shanghai did not meet national standards. In 2010, the association selected new renovated houses in the city as a sample [new news price house type review] for testing. It was found that in 30 sample houses, the indoor air quality fully met the national standard of 12 sets, and the unqualified rate reached 60%. Among them, 15 households were unqualified, accounting for 50% of the total. The excess value was mostly within 2 times of the national limit standard. In general, the study, bedroom and storage room in the newly renovated room are the hardest hit areas of pollution.
“Pomelo peel, durian, garlic, onion, all these methods can not solve the fundamental problem.†For many folk purification tricks that have emerged in the private sector, the industry believes that although these items can reduce the smell in the room, they cannot be from the source. Eliminate pollutants.
Different pollutants have different characteristics, and special air treatment needs to be carried out under the premise of maintaining indoor ventilation and ventilation. Different methods of decontamination can be adopted separately. It is best to choose a qualified environmental management company for treatment, or use an air purifier to improve air quality. It can also be treated by adsorption, coating, photocatalytic catalysis, chemical spray professional agents. Wait.
