Living in a room with formaldehyde with windows open all the time

It is best not to live in a room that already contains formaldehyde, and you should open the windows for ventilation for a long time to protect your body. Also, do not live in a room during the formaldehyde removal period. It should be ventilated for a while before you can move in. Families with children or pregnant women should pay more attention.

Through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, and the air cannot circulate between indoor and outdoor spaces. Not only will the formaldehyde content in the indoor air increase, but radon gas will also continue to accumulate and even reach a very high concentration.

Advantages: good effect, no cost Disadvantages: long time, generally it takes more than three years to remove formaldehyde.

Physical adsorption

The pores of Han Purple are tailored according to the size of formaldehyde molecules. The size of formaldehyde molecules is about 0.27 nanometers. When making pores, complex technical means are used to concentrate the pore size at about 0.27 nanometers. The pore size that is suitable for the size of formaldehyde molecules can not only selectively adsorb formaldehyde preferentially, but also help to better lock the formaldehyde molecules, effectively avoiding release after adsorption. At the same time, its surface is polar. For formaldehyde, which is a polar molecule, it has an active adsorption effect, which completely changes the technical disadvantages of passive adsorption of activated carbon and other adsorption products.

Research and use have proved that Gaolaozhuang gypsum lamps have a natural negative ion diffusion function, which can effectively absorb harmful gases such as indoor formaldehyde, remove negative energy from other stones, and purify environmental energy.

Negative ions can effectively remove harmful gases such as formaldehyde in the room and purify the indoor air. The Chinese Academy of Sciences has confirmed through experiments that the efficiency of small-particle negative ions in removing formaldehyde is over 73.33%, and long-term use can reach 99%.

1. Use water, vinegar, and black tea to soak water to remove formaldehyde

Many people on the Amethyst Internet said that since formaldehyde is soluble in water, you can place a few basins of water at home to absorb the formaldehyde, or use vinegar or black tea to soak in water. It is a fact that formaldehyde is easily soluble in water, alcohol and ether. Free formaldehyde in the air will dissolve into water when it encounters water during movement, which is similar to the adsorption principle of activated carbon. The contact area between a basin of water and the air is only the size of the basin, while the specific surface area of ​​the pores inside 1 gram of activated carbon can reach as large as a football field. Even if you place a hundred basins of water in the room, the adsorption effect will not be much stronger than a small bag of activated carbon. Therefore, it is obviously unrealistic to use water, black tea, vinegar and other methods to absorb formaldehyde. The release of formaldehyde is closely related to indoor temperature and humidity. As the temperature in the air increases, the amount of formaldehyde released will increase greatly. Experimental results show that if the relative humidity in the air increases by 10%, the indoor formaldehyde emission will increase by about 5%.
