What are the advantages and disadvantages of high temperature fumigation to remove formaldehyde

Formaldehyde is a substance with a very high carcinogenicity rate and can induce leukemia. Formaldehyde is a colorless and odorless substance, but it can cause serious irritation to people's eyes and noses. Formaldehyde is miscible with water and ethanol. Formaldehyde will be produced after the new house is decorated, so you can only move in after the formaldehyde is completely removed. So what are the advantages and disadvantages of high-temperature fumigation to remove formaldehyde?

First, what are the pros and cons of high-temperature fumigation to remove formaldehyde? High-temperature fumigation cannot completely remove formaldehyde, but only expels the formaldehyde on the surface. The odor will temporarily decrease, but it will rebound. If you are not in a hurry to move in, you can keep the room dry and ventilated to effectively remove formaldehyde, but this method takes a long time, or you can ask a professional team to remove and measure the indoor formaldehyde.

Second, the wrong method: using onions and other fruits and vegetables to remove formaldehyde. This type of method does not have the function of removing formaldehyde. It just uses the smell it releases to cover up the smell of indoor pollution, which can make us mistakenly believe that pollutants such as formaldehyde are gone, but in fact the formaldehyde has not been reduced. If you check in at this time, it will have serious consequences. Putting a few basins of water can remove formaldehyde. Formaldehyde is soluble in water, but it cannot effectively control formaldehyde. The amount of water in a few basins is too small and the contact area with the air is also too small, so the efficiency of purifying formaldehyde is extremely low. In addition, as the weather gets hotter, water is more likely to attract small insects, and high humidity can easily cause mold, which will be even more harmful to human health.

Third, scientific method: timely ventilation - air exchange. As long as we open the windows and let the wind enter the room, causing air exchange between indoor and outdoor areas, we can achieve a good formaldehyde control effect. Therefore, we should ventilate more often in our daily life to better control formaldehyde. However, the formaldehyde release period is as long as 3-15 years, and there are many situations in life where windows cannot be opened, so it is best to use it in combination with other formaldehyde removal methods.

What are the advantages and disadvantages of high-temperature fumigation to remove formaldehyde? Nowadays, many people in the industry use fumigation methods to remove formaldehyde. The main principle of fumigation is to accelerate the release of formaldehyde and TVOC in the board through high temperature, while assisting with formaldehyde removal agents to achieve the effect of rapid formaldehyde removal. However, some formaldehyde release sources are not suitable for high-temperature fumigation because it will damage the material. Different methods are used for different pollution sources.
