If people have any questions, they can find answers online, but many of them are unreliable. The problem of removing formaldehyde from new houses has been a big problem for us. Many people will see such a method on the Internet, that is, a basin of water in your new house, in addition to aldehyde, also say that formaldehyde aqueous solution is formaldehyde, so water can remove formaldehyde.
I want to say that people who have studied chemistry should be clear that although the aqueous solution of formaldehyde is formaldehyde, which is mixed with water, but under certain conditions, formaldehyde and water molecules, the efficiency of formaldehyde in water is very, very low under normal conditions, so do not rely on the network rumors of water except for aldehyde, which must use scientific methods.
Method 1: temperature control and ventilation
We all know that formaldehyde is volatile at high temperature. We can use some heating equipment to raise the temperature of our home a lot, so that formaldehyde gas will volatilize in large quantities, and then formaldehyde can be removed through window ventilation. Repeated operation for several times can remove most of the formaldehyde in the home. This kind of temperature control ventilation will be better to control the temperature above 19 ℃.
Method 2: tachydrite
It is one of the main materials in modern times. The effect of removing formaldehyde and removing formaldehyde is 10 times of that of activated carbon. It can also decompose formaldehyde and absorb formaldehyde without saturation. It has an effective period of up to 3 years. There is no need to worry about the secondary pollution caused by reabsorption saturation.
Method 3: concentrated brine adsorption
Formaldehyde can be dissolved in concentrated salt water, so we can put some concentrated salt water at home to absorb formaldehyde. If there is a peculiar smell at home, we can also put orange peel in concentrated salt water. Although an orange can't absorb formaldehyde, it has a good effect on indoor air deodorization. When using concentrated salt water to absorb formaldehyde, we should also pay attention to it and replace it regularly.
