About the flooring formaldehyde exceeds the standard
Why does the floor contain formaldehyde? This starts with the material of the
floor. The first common floor can be divided into two categories: solid wood
flooring and artificial flooring. The selection of solid wood flooring is
natural, and the material itself does not contain chemicals harmful to the human
body. However, due to the fact that the solid wood flooring is close to real
trees, it has the disadvantages of easy wear and maintenance. In order to reduce
the wear and tear on them in life, people will put a layer of wood lacquer on
the solid wood floor. The wood lacquer contains formaldehyde, so it will pollute
the indoor air. For man-made boards, I believe many people know that it is also
a common source of indoor pollution. When processing artificial boards, it is
necessary to add adhesives to form the mold. The adhesive contains formaldehyde,
so it will also pollute the indoor air.
Although many families have taken measures to control indoor environmental pollution just after laying the floor, the release period of formaldehyde is relatively long, up to 3-15 years. Hot and hot weather in summer will accelerate the volatilization rate of formaldehyde, so the floor is easy to reverse in the summer. Working and studying in a room contaminated with formaldehyde for a long time may cause formaldehyde poisoning.
There are many symptoms of formaldehyde poisoning, and the specific symptoms will be affected by the degree of poisoning. Formaldehyde is irritating. When people are in an environment with excessive formaldehyde concentration, formaldehyde will cause irritation to the human respiratory tract, skin and eyes, causing symptoms such as sore throat, chest tightness and cough. Patients with mild form of formaldehyde poisoning may feel dizziness, headache, and general malaise; patients with moderate form of formaldehyde poisoning may have worse symptoms, persistent cough, hoarseness, difficulty breathing, etc.; patients with severe formaldehyde poisoning may experience coma and shock. If symptoms are not treated in time, there is a danger of life.
Formaldehyde pollution is a great hazard. Once there is a hidden danger of formaldehyde pollution in summer, scientific treatment measures should be taken immediately. How to control indoor formaldehyde pollution? There are several good ways to treat formaldehyde:
1. Adhere to ventilation and ventilation. Especially in the north-south transparent house, the north-south doors and windows are opened, and the convection formed will discharge indoor harmful substances to the outside, and the entry of fresh air can also reduce the concentration of indoor harmful gases, although ventilation and ventilation are slower than formaldehyde. But it is also a good way to save money and effort.
2. Air purifier treatment. The air purifier is a new product in recent years, and it has a good effect on the treatment of the indoor environment. However, the high cost of the air purifier will increase the cost of indoor pollution control.
3. Applicable adsorption decomposition method Effectively decompose formaldehyde into carbon dioxide and water after adsorption
