Description

A negative ion ecological density board

technical field

The invention belongs to the technical field of density boards for decoration, in particular to an anion ecological density board. the

Background technique

Various building materials used for interior decoration contain various volatile organic compounds. These toxic and harmful gases include: halogenated hydrocarbon compounds, aromatic hydrocarbon compounds (such as benzene), aldehyde compounds (such as formaldehyde), ketones and lipids. Such compounds have caused great pollution to indoor air and constituted a great potential hazard to human health, which has aroused widespread concern in the society. the

The negative air ion technology is applied to density board products, and the used density board releases negative air ions, especially negative oxygen ions, in the room for a long time. Because it is similar in structure to superoxide anion radical (O2-), it has similar biological activity and can make living biological cells negatively charged, thereby making the virus lose its ability to attack cells. For example, in an artificial air negative ion environment, the number of mold and bacteria in the air can be reduced by more than 90%. After negative oxygen ions are inhaled into the human body, they can regulate the excited state of the nerve center, improve the ventilation function of the lungs, improve blood circulation, promote metabolism, enhance the ability of the immune system, inspire people, and improve work efficiency. , asthma, flu, insomnia, arthritis and many other diseases have a certain therapeutic effect, so people call negative ions "vitamins in the air" and "longevity". the

On the other hand, traditional density boards have single functions, are prone to produce harmful substances such as formaldehyde, are very easy to cause harm to the human body, and do not have the functions of repelling mosquitoes and relieving stress, so they can no longer meet people's daily needs. the
