How long does it take for the formaldehyde to evaporate after the floor heating is turned on

Most people would not dare to move into their house quickly after it has been renovated because there will be formaldehyde in the renovated house. If the formaldehyde invades the human skin and body for a long time, it will cause illness and may also produce carcinogenic substances through respiratory breathing. To deal with formaldehyde, not only should activated carbon be placed indoors, but windows should also be opened for ventilation, so that the air can circulate and the formaldehyde can evaporate faster.

How to remove formaldehyde fastest

Method 1: Activated carbon adsorption method to remove formaldehyde hazards

Activated carbon is internationally recognized as an expert in drug absorption. Activated carbon masks and gas masks all use activated carbon. This product uses the physical effect of activated carbon to deodorize and remove toxins; it does not contain any chemical additives and has no effect on the human body. Placing two to three discs in each room can basically remove all indoor odors within 72 hours. This method can be used for medium and low pollution, or it can be used in combination with other chemical methods to achieve better comprehensive treatment effects.

Method 2: Ventilation method to remove formaldehyde hazards

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.

Method 3: Local tricks to remove formaldehyde hazards

Soak 300 grams of black tea in two basins of water, put it into the room, and open the windows for ventilation. Within 48 hours, the indoor formaldehyde content will drop by more than 90%, and the irritating smell will be basically eliminated.

Method 4: Plant deodorization method to remove formaldehyde hazards

Plant decontamination can be chosen for medium and low pollution: In general, in environments where indoor environmental pollution is light or moderate, and pollution values ​​are below 3 times the national standard, plant purification can achieve relatively good results.

Choose and place plants according to the different functions and size of the room. Generally speaking, it is more appropriate to place two pots of plants 1.5 meters high in a room of about 10 square meters.

Method 5: Chemical method to remove formaldehyde hazards

1. Treatment with sprays and other drugs can easily cause secondary pollution and may damage furniture, while activated carbon is a physical adsorption method, which is very safe, harmless to the human body, and has anti-mildew and anti-corrosion effects on furniture.

2. It advocates one-time removal (experts question, not credible), but the release of toxic gas in the home is a slow process, so if it is removed today, the smell will reappear in a few days, and the price is not low.

3. There are too many products to distinguish. Although many formaldehyde-control products are labeled as "high-tech" and "environmentally friendly", they actually use some inferior chemical synthetic substances. Although these products can eliminate formaldehyde to a certain extent, they may also re-produce other pollutants and cause secondary pollution.

Method 6: Photocatalytic decomposition method

Under the stimulation of light, the catalyst in the photocatalyst generates negative ions and hydroxyl free radicals with oxygen and water in the air, which can oxidize and decompose various organic and inorganic pollutants, and eventually degrade them into harmless substances such as carbon dioxide, water and corresponding acids, thereby achieving the effect of decomposing pollutants and purifying the air.

Therefore, consumers must be vigilant when purchasing formaldehyde control products. For example, chemical air treatment products are obtained through artificial synthesis, and many of them are aromatic compounds. Almost all aromatic compounds contain benzene ring compounds which have been proven or suspected to be carcinogens. In addition, many chemical products are oxidizing and corrosive, which can easily damage utensils and cause harm to operators and residents. When the coating of closed concealing products ages and the weather becomes hot and humid, the film is easily damaged, and harmful substances such as formaldehyde will be released, becoming a hidden "timer" in the home.
