Formaldehyde is a common indoor environmental pollutant. It is not only easy to cause formaldehyde pollution after decoration, but there are still many factors that affect the formaldehyde reform. The edge-sealing method, bearing capacity, volatilization route, environmental changes and storage time and conditions of the sheet finish will affect the release rate of formaldehyde. In the summer, the weather gradually becomes hot, the sunshine time becomes longer, the air humidity becomes larger, and the rate of occurrence of harmful substances such as formaldehyde is also accelerated. Therefore, summer is also a season in which indoor formaldehyde pollution is high.
Like newly renovated houses, many families find that even if they have been renovated for a while, they will produce a pungent smell of formaldehyde in the summer, because the release period of formaldehyde is relatively long, up to 3-15 years. Although formaldehyde is usually present in the room, it is difficult to find formaldehyde in the air by smell because of its low concentration. The increase in temperature in summer promotes the release rate of formaldehyde, the concentration of formaldehyde in the room increases rapidly, and the pungent odor becomes obvious, which will be discovered. Therefore, the treatment of formaldehyde, the effort should be in the usual, if you have a pungent smell in your home, it means that formaldehyde pollution is already very serious.
So how to remove formaldehyde pollution? Since it is caused by formaldehyde pollution caused by the weather, is it effective to open the air conditioner in addition to formaldehyde? Although the air conditioner in addition to formaldehyde sounds reasonable, the actual effect is not satisfactory. The reason is very simple. When using air conditioning and cooling, in order to achieve a good cooling effect, the door and window should be closed. If you want to discharge harmful substances to the outside, you need the power of the air conditioner exhaust fan. However, the exhaust fan of the air conditioner has limited exhaust capacity. Although the indoor temperature decrease delays the release rate of formaldehyde to a certain extent, the formaldehyde released in the room gathers indoors, and the formaldehyde concentration does not decrease, which still causes harm to human health. .
In addition to air-conditioning in addition to formaldehyde, there are many common methods of formaldehyde treatment. Which of these are strong in governance and which are “pseudo-scienceâ€. The following is an analysis and analysis by Xiaobian.
Method 1: Open the window ventilation method. The window opening ventilation method is a simple operation method for treating formaldehyde. The convective movement of air promotes the emission of harmful substances such as formaldehyde to the outside, thereby achieving the purpose of reducing the concentration of indoor pollutants. Although this method is effective and saves the cost of treatment, the speed of formaldehyde treatment is slow. It is not recommended that the renovation of new homes is just over. The use of homes in an emergency can usually be used together with various management methods.
Method 2: Physical adsorption method. The use of activated carbon and Maya blue adsorption is also a common method of formaldehyde treatment. Activated carbon and Maya blue are rich in pores and can adsorb harmful substances such as formaldehyde into their pores. By physical adsorption to control formaldehyde pollution, there will be no secondary harm, suitable for families with children, pregnant women and the elderly.
Method 3: Chemical decomposition method. Chemical fresheners can decompose formaldehyde by chemical reaction, and have strong treatment ability. It is a relatively popular formaldehyde treatment method in the early stage. However, with the introduction of fresheners, their shortcomings have begun to emerge, that is, in the course of chemical reactions, new compounds are also produced, and some compounds are toxic, causing secondary pollution. Therefore, for the safety of you and your family, it is recommended not to choose the chemical decomposition method.
Method 4: Plant adsorption method. Plants can adsorb carbon dioxide and release oxygen through photosynthesis, and some plants can also absorb certain formaldehyde. However, relying on plant control for indoor pollution is not realistic in practice, and plant adsorption capacity is very weak and can be used as an auxiliary means.
Nowadays, the weather is getting hotter and hotter, and the temperature is getting higher and higher. For the safety of you and your family, please manage indoor pollution as soon as possible. I hope this article can help your life.
