Now many owners use environmentally friendly materials and furniture during renovation to avoid decoration pollution, but the so-called environmentally friendly materials are not polluted? According to previous analysis of the testing data of 565 households within 1 year of decoration, the over-standard rate of formaldehyde was 71%, the over-standard rate of benzene series was 19%, and the over-standard rate of TVOC was as high as 73%. Why use environmentally friendly decoration materials, and the pollution is still exceeding the standard?
What is environmentally friendly sheet?
At present, in the international market, the formaldehyde limit level in the plate is divided into three levels of E2, E1 and E0, namely E2≤5.0mg/L, E1≤1.5mg/L, E0≤0.5mg/L. Although the formaldehyde content of E0 is very low, this does not mean that the E0 plate is completely free of formaldehyde, and even the E0 grade plate is used more, and the formaldehyde will exceed the standard.
The E1 environmental protection standard is a national mandatory health standard. It is a mandatory “safety standard line†of 1.5 mg/L or less, and the pollution content is about 3 times that of the E0 grade plate. Therefore, the E1 plate will be used more than the standard. This is the reason why the environmental protection panels used in decoration and furniture are clearly used, or the formaldehyde is exceeded.
1. Environmentally friendly sheet does not mean no pollution
There is still a certain amount of pollutants in the environmentally friendly materials, and after a large amount of use, the pollution will also exceed the standard due to the cumulative effect. Especially in the process of fine decoration, there are many materials used, so reliable pollution detection must be carried out before the stay.
2. Do not blindly believe in famous brands
In many cases, brand-name furniture or plates are often better than ordinary products, but in actual inspections, nearly 30% of households with excessive pollution are brand-name products that consumers trust. According to the owner's reaction, these furniture will also have a serious smell and no improvement in ventilation for several months. Therefore, the products of non-known brands may not be of poor quality, and the brand products may not meet the quality standards.
3. Ventilation time is too short
Usually people think that the new home should be ventilated for half a year, but the length of ventilation depends on the actual pollution situation. Some families are simple to decorate and use materials environmentally friendly. They may be ventilated for two months. Some families have complicated decoration and use a lot of plates. Exceeding the standard is serious, and ventilation is still unable to meet the standard for one year. Both of these situations are very common. It is necessary to flexibly choose the length of ventilation according to the actual situation of the decoration. Not all households must be ventilated for half a year.
4. Without formaldehyde, there is no need to remove formaldehyde?
The most obvious performance of decoration pollution is the smell. The smell often indicates that the pollution is very serious, but it should be noted that no smell does not mean no pollution. For example, formaldehyde is almost invisible within 5 times of the standard. Low-concentration formaldehyde is not as irritating as people think, and odor is generally benzene and TVOC. Therefore, when there is odor, it is necessary to pay attention to pollution control, but no smell does not mean that formaldehyde is not needed, and the actual test data should be referred to.
5. Can you feel safe when you check the standard?
The continuous release of formaldehyde from the board to the air lasts for three to fifteen years. Even if the test is up to the standard on a certain day, it cannot be said that it will always reach the standard in the future, especially when it is hot in summer or when there is heating in the north and winter, it is a high incidence of pollution recurrence.
So how should the decoration of formaldehyde be removed?
1. More ventilation
Ventilation is the most basic and cost-effective method of removing formaldehyde, which uses air flow to remove pollutants and bring fresh air. Although the time for ventilation in addition to formaldehyde is relatively slow, ventilation cannot be ignored regardless of the formaldehyde removal product used.
2. Adsorption of formaldehyde
In addition to formaldehyde, it is necessary to match a variety of methods, and only a single ventilation in addition to formaldehyde is likely to remain dead corners. In the corners, inside the furniture, in the drawers, and in other corners where ventilation is difficult to reach, you can use activated carbon bags to absorb the pollution. Activated carbon has developed pores, which can be targeted to strengthen the treatment and improve the efficiency of formaldehyde removal. In addition to activated carbon, Maya Blue can also be used to prevent secondary pollution.
3. Plants in addition to formaldehyde
Plants such as spider plant, green radish, and poisonous grass can absorb harmful toxic gases to a certain extent. However, the conversion rate of plant pollution to decoration is very low. In order to achieve the desired formaldehyde removal effect, it is not enough to fill a house with green plants. However, plants can increase the oxygen content and humidity in the air. It is still a good choice for fresh indoor air and beautifying the environment. In short, it is beneficial and harmless.
