Light ventilation can not completely solve the pollution
Because many substances harmful to the human body are deeply hidden inside the decorative material, the release involves a fairly complicated dynamic process. For example, the release of free formaldehyde in the plate includes: the residual reaction in the plate making process is not involved in the reaction. Free formaldehyde; the intermediate product that is not completely reacted during the curing process of the adhesive is hydrolyzed and oxidized by the environmental factors to release formaldehyde; the cured adhesive is affected by environmental factors, slowly oxidatively hydrolyzed to release formaldehyde, etc. According to Japanese scientists, the release time is proved by experiments. It lasts for 3 to 15 years, so decoration pollution cannot be completely eliminated in a short time. However, it can be said that vacant and open room windows to enhance ventilation can accelerate the volatilization of toxic pollutants, significantly improve indoor air quality, but because formaldehyde and other pollutants release time is too long, it is impossible to completely evaporate in a short period of time, so it is recommended to decorate and Indoor air quality testing is performed after the furniture is entered to ensure indoor air health.
Please check with a specialized agency
After the completion of the decoration, the inspection should be carried out in strict accordance with the national testing standards, and must be tested after all the furniture enters the scene, so as to ensure the accuracy of the test results, and the detection can not be exceeded. Because the inspection after the decoration does not exceed the standard does not mean that there is no pollutant in the room, it only means that the decoration pollutant index is within the national limit value. If the release of furniture pollutants is added later, it is difficult to determine the indoor air quality standard, which is very It’s hard to stay in peace.
There will be pollution when there is decoration
As long as the decoration will bring a certain amount of indoor pollution. It is only the degree of pollution is different. If the indoor pollution index is controlled within the relevant national standards, it will not cause too much harm to the human body.
Innocent people do not mean complete security
As long as indoor pollutants do not exceed the limit, it will not immediately lead to illness or death, but its toxicity is chronic. Living in a problematic indoor environment for a long time, people's immunity must be affected, and toxic substances are in humans. Accumulation in the body will eventually lead to illness in the human body. In reality, most people are sick, and often do not think of it because of home pollution. Therefore, in order to be healthy, it is recommended to retreat an indoor air quality test after moving into a new home. If the standard exceeds the standard, it can be comprehensively managed by a professional management company.
Environmentally friendly materials cannot completely avoid pollution
Buying good furniture and environmentally friendly materials can actually reduce indoor air pollution. However, every piece of qualified furniture and environmentally-friendly materials is not released without pollutants, but the release amount is within the corresponding national standards, but definitely no release of pollutants, such as national standards. The E1 standard specified in the free formaldehyde emission standard for plates requires a formaldehyde release limit of ≤1.5 mg/L (dryer method), which is equivalent to ≤9 mg/100 g in the perforation extraction method (meaning that every 100 g is absolutely The release of free formaldehyde from dry sheets should not exceed 9 mg). Since the space of the house is constant, even if each product (furniture) is an environmentally-friendly product that meets the standards, the pollutants released by a large number of furniture and environmentally-friendly decorative materials will continue to increase with the increase in the absolute number of furniture and materials. Lead to excessive indoor pollution.
