Misunderstanding of decoration : Control indoor air pollution
Myth 1: A complete reliance on short-term ventilation or ventilation can solve the problem.
As a basic environmental protection measure, ventilation treatment can improve indoor pollution, but because most harmful substances will be slowly released for 3-15 years, it is not a few months of ventilation and ventilation can solve the problem. Within 3 years, you have to take a big risk of causing cancer and cancer; and the winter and summer in northern China need to close the doors and windows. Moreover, most of the living rooms and office buildings are not ideal for ventilation, and the ventilation effect will be greatly reduced. In addition, formaldehyde is used as an example. Free, adsorbed, and combined exist in three states. Only the venting treatment in the free state can be eliminated and must be more than 4 times the normal wind speed.
Frequent window ventilation is a healthy living habit that medical experts unanimously recommend, but if formaldehyde pollution is serious, ventilation alone cannot solve the problem fundamentally. Because the formaldehyde release in artificial boards usually takes more than 8 years, not to mention the summer, do you open the window or turn on the air conditioner? What about winter and the rainy season?
Myth 2: I think there is no pollution and no pollution.
Indoor formaldehyde pollution can be seen everywhere: plates, furniture, wallpapers, carpets, paints, glues, etc., and the formaldehyde release period in the plates is more than 8 years. Even if it is not smelled, it can endanger health, especially indoors. Poor air circulation, once exceeded the standard will seriously endanger human health.
Misunderstanding 3: Avoid pollution by using environmentally-friendly materials
Compliance with the standard means that the release of harmful substances is lower than the national standard. For example, the mandatory national standard for formaldehyde emission from wood-based panels and their products is not more than 1.5 mg per liter of air. However, if the same material is accumulated and used in a large area within a certain area, the harmful substances are also accumulated, and finally, the harmful objects in the renovated house may exceed the standard.
With the increase of people’s awareness of environmental protection and the improvement of consumers’ level, many families adopt high-quality environmentally-friendly materials, which of course can greatly reduce the harmful gas content and reduce the possibility of harm, but it is still difficult to meet environmental protection standards because of the decoration process. Putty, adhesive, gum water and other auxiliary materials should be used in large quantities, and even strong ones may release harmful gases.
Misunderstanding 4: Governing indoor pollution is to eliminate formaldehyde
Formaldehyde mainly comes from artificial board, furniture and decoration used in adhesives and synthetic fabrics such as carpets. Excessive concentrations can cause nausea, vomiting, cough, chest tightness, wheezing and even emphysema. It is one of the main pollutants of indoor air. Because it is the ‘number one killer’ of indoor pollution, it is highly recognized. Many consumers believe that eliminating indoor pollution is to eliminate formaldehyde, but it is not. In addition to formaldehyde, a large number of chemical materials used in building decoration materials, such as paints, solvents, thinners, adhesives, benzene series, such as benzene, toluene, xylene, etc., long-term inhalation of air with a higher concentration of benzene Causes chronic poisoning of benzene, triggers allergic dermatitis, laryngeal edema and thrombocytopenia, and can also cause aplastic anemia.
Myth 5: Over-reliance on plants
The green plants used to decorate the living environment are a powerful tool for purifying indoor air. Some home improvement people like to put a few pots of flowers in the living room, which not only can beautify the environment, but also make people happy. For example, ivy and iron trees can absorb benzene and organic matter, and indoor plants such as spider plants and aloe can absorb formaldehyde. However, relevant experts said that although some flowers have a little effect of removing pollution, the characteristics of plant action are slow, long time, and the amount of adsorption and decomposition is very limited. For the large-scale decoration, the effect is almost negligible. Moreover, some flowers are not suitable for living in the living room. For example, night scent will emit a lot of stimulating granules in the evening, which will make people with high blood pressure and heart disease feel dizzy, depressed and uncomfortable, and even worse. The rich fragrance of rose flowers will cause some people to have chest tightness, discomfort and suffocation. Difficulty breathing; oleander can secrete a milky white liquid. After a long period of contact, it can cause poisoning, causing drowsiness, mental decline and other symptoms.
Misunderstanding 6: First renovation and then governance
‘Which decoration materials sold in the market do not pollute the environment at all, it’s not too late to renovate the house after it has been renovated!’ Many consumers started to really consider the pollution of their home improvement after they installed it at home, but took remedial measures afterwards. Often the best results are not achieved. Among them, a large part of them believe that the use of air fresheners can eliminate harmful gases such as formaldehyde. ‘After the renovation, there is no harmful gas using a little air freshener,’ said Mr. Yu.
Experts say that the use of air fresheners can only mask harmful gases with odors with their fragrant gases, and they cannot be adsorbed or decomposed fundamentally. In the decoration process, the formaldehyde in the material is thoroughly removed by formaldehyde scavenger, and the odor removal products such as decoration deodorant are used to thoroughly treat the benzene series, and the relevant aspects of the treatment before the completion of the decoration are to remove harmful indoors. Effective measures for gas. According to the reporter, there are many kinds of aldehyde removal products currently on the market. Such as formaldehyde trapping agents, scavengers, etc., there are spray, brush, adsorption, machine blowing, purification and so on. At the time of renovation, the appearance of these products will undoubtedly inject a “cardiotonic agent” into the health of consumers.
