Home decoration should be something that every ordinary person will encounter. After we finished the decoration, we happily moved into the new house, but did we think of the pollution that will occur after the renovation? Let’s talk about the pollution that we should all know about home decoration. 10 points of common sense.
First, the decoration is equal to pollution
As long as there is decoration, it 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. According to statistics, 90% of newly renovated houses have exceeded the standard of pollution, especially formaldehyde is more serious than standard, and more than 95% of them do not meet national standards.
Second, there is no smell, there may be pollution exceeding the standard
Some harmful substances are colorless and odorless, so they are not necessarily noticeable. Colored and odorous substances are not always detectable. For example, formaldehyde, which everyone has heard, is a colorless and irritating gas, but it is generally more than three times higher than the national standard. Therefore, in order to make a health recommendation for the family, please check with a professional testing agency to determine if there is any pollution.
Third, environmentally friendly materials do not mean no pollution
Buying good furniture and environmentally friendly materials can actually reduce indoor air pollution, but each piece of qualified furniture and environmentally friendly plates is not free of pollutants, but the release amount is within the national standards, but definitely no pollutants are released.
For example, the E1 standard specified in the National Standard for Free Formaldehyde Release of Plates requires a formaldehyde release limit of ≤1.5 mg/L. Because the space of the house is constant, that is to say, even if every piece of furniture and environmentally friendly materials are environmentally friendly products, the pollutants released by a large number of furniture and environmentally friendly decorative materials will continue to increase with the absolute number of furniture and materials. Accumulating, leading to excessive indoor pollution.
Fourth, the human body does not have an abnormality does not mean indoor environmental safety
As long as the indoor pollutants do not exceed a certain amount, 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 Accumulation in the human 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, for health, it is recommended to conduct an indoor air quality test before moving into a new home. If the standard exceeds the standard, it can be comprehensively managed by a professional management company.
Fifth, light ventilation can not completely solve the pollution
Each indoor pollutant has a release cycle, and the release of formaldehyde is the most harmful to us for 3 to 15 years.
It is not a problem that can be solved by ventilation for a few months. In the period of 1 to 3 years of intensive dispersal, you have to take a big risk of causing cancer and cancer. And formaldehyde exists in the three states of free, adsorption and combination. Only the free formaldehyde can be eliminated by ventilation, and it must be more than 4 times of the normal wind speed. However, it is safe to say that vacant and open windows in the room to enhance ventilation can accelerate the volatilization of toxic pollutants and significantly improve indoor air quality.
Sixth, plants purify the air
It is now familiar to know that plants are selected after filtration to filter or adsorb harmful substances in the air. But first of all, it is impossible for plants to absorb the harmful substances in the decorative materials, so it is still impossible to fundamentally solve the threat of pollution. Secondly, when choosing plants placed in the living room, it is necessary to consult relevant experts to select plants that are good for improving indoor air quality. Otherwise, mistakes in selection may lead to worse results. Third, the absorption of indoor pollutants by plants is minimal and can only be used as an aid.
Seven, deodorant is only a temporary solution
The deodorant itself does not have the function of treatment, or even the absorption and absorption, the deodorant can only cover the effect, and the pollutant in the chamber a does not reduce any. If the deodorant is improperly purchased, it will even have a worse impact. . In short, the deodorant is not better than the use.
Eight, activated carbon can not completely solve the pollution
Placement of activated carbon in the room will have a certain relief effect on indoor air pollution, but this method still cannot solve the problem fundamentally. Activated carbon aims to purify and improve indoor air quality by adsorbing toxic substances in indoor air. That is to say, it is a relatively passive purification mode, and only toxic volatiles within its adsorption range can be adsorbed. In addition, activated carbon also has a problem of adsorption saturation, which can no longer exert adsorption after adsorption saturation, and each household does not have the detection conditions, and we cannot know when to reach saturation.
IX. After the renovation, special agencies should be invited to conduct inspection and treatment.
After the completion of the decoration, the inspection shall be carried out in strict accordance with the national testing standards, and in order to ensure the accuracy of the test results, it must be tested after the decoration is completed and all the furniture enters the site. If you don't exceed the standard, you can feel at ease. Because the inspection after the decoration does not exceed the standard does not mean that there is no pollutant in the room, but only refers to the decoration pollutant index within the national limit value. If you add the release of furniture contaminants, it is difficult to determine the indoor air quality standards, it is difficult to rest assured.
X. Dealing with pollution is best started before the renovation
Indoor environmental governance can be divided into two types: pre-intervention and post-remediation.
The so-called pre-intervention type starts from the arrival of decorative materials, and the decorative materials (mainly the plates) are treated in a targeted manner in advance, and the decoration is completed. After the furniture enters the site, the indoor environment is comprehensively cleaned and treated.
The post-remediation type is the comprehensive purification of the indoor environment that is carried out after the decoration is completed and the furniture is found to be inconsistent with the indoor air quality.
Obviously, the pre-intervention type can completely solve the pollution of home decoration. At the same time, if the product with antibacterial effect is tested by the national authority disease control institution, it can also improve the human immune function to a certain extent.
