What is the mechanism by which Light Negative Oxygen Ions decompose formaldehyde?
COSIO lighting has created a "black technology",it innovatively integrates light elements with negative ion elements and has the function of decomposing formaldehyde. Let's go and see how to do it.
As people pay more attention to health, the dangers of formaldehyde are becoming more and more familiar to people. "Formaldehyde removal" has become one of people's rigid needs. As a result, many companies and institutions specializing in formaldehyde removal have been born. Formaldehyde can be said to be “everywhere”. Formaldehyde is one of the main raw materials of adhesives. Adhesives are the most important consumption area of formaldehyde in my country and the consumption accounts for the largest proportion, accounting for about 40% of the total consumption. The adhesive products produced mainly include urea-formaldehyde resin glue, phenolic resin glue and melamine-formaldehyde resin glue, which are mainly used as treatment agents for wood processing, molding compounds, coatings, textiles and paper. Formaldehyde is widely found in household products, furniture, clothing, plastics, leather and other products. However, only formaldehyde exceeding a certain level will be harmful to the human body. For specific values, please refer to the relevant standards of various countries. Therefore, there is no need for us to "talk about formaldehyde discoloration".
So, what is formaldehyde? What harm does it have?
Formaldehyde is an organic compound with the chemical formula HCHO or CHO and a molecular weight of 30.03. It is a colorless and irritating gas that is irritating to human eyes and nose. The gas relative density is 1.067 (air = 1), the liquid density is 0.815g/cm3 (-20℃), the melting point is -92℃, the boiling point is -19.5℃, and it is easily soluble in water and ethanol. The concentration of formaldehyde aqueous solution can reach up to 55%, usually 35%-40%, usually 37%, which is called formaldehyde water,commonly known as Formalin. On October 27, 2017, in the list of carcinogens published by the World Health Organization’s International Agency for Research on Cancer, formaldehyde was included in the list of Class 1 carcinogens. On July 23, 2019, formaldehyde was included in the list of toxic and harmful water pollutants.
The hazards of formaldehyde are divided into four types: acute toxicity, chronic toxicity, mutagenicity, and carcinogenicity. Acute formaldehyde poisoning manifests as irritation to the skin and mucous membranes.Inhaling high concentrations of formaldehyde can cause respiratory irritation symptoms, including sneezing, coughing, and burning sensations in the nose and throat. In addition, it can also induce bronchial asthma, pneumonia, and pulmonary edema. Chronic formaldehyde poisoning manifests itself as reducing the body's respiratory function, the information integration function of the nervous system, and affecting the body's immune response. It also has toxic effects on the cardiovascular system, endocrine system, digestive system, reproductive system, and kidneys.Formaldehyde is mutagenic and causes mutations in Salmonella typhimurium and Escherichia coli. The carcinogenicity of formaldehyde is manifested by its ability to cause gene mutations and chromosomal damage in mammalian cell nuclei. Formaldehyde has a combined effect with other polycyclic aromatic hydrocarbons, such as benzopyrene, which can increase toxicity.
There are many ways to "remove formaldehyde", and we will not elaborate on them one by one. Currently, Our company has created a "black technology",it innovatively integrates light elements with negative ion elements and has the function of decomposing formaldehyde. This is Light Negative Oxygen Ions (LNOI) technology. So, what is the mechanism by which Light Negative Oxygen Ions (LNOI) decompose formaldehyde?
Negative ions, also called negative oxygen ions, are negatively charged gas ions in the air. Most of the free electrons generated when air molecules are ionized under the action of high pressure or strong rays are obtained by oxygen. Therefore, air negative ions are often collectively referred to as "negative oxygen ions". Negative ions, like sunlight, are essential substances for human beings. It can promote the body's synthesis and storage of vitamins, strengthen and activate the body's physiological activities. At the same time, negative ions are also necessary substances to maintain the dynamic balance of the earth's life environment, and are one of the fundamentals of human survival and health.
Light Negative Oxygen Ions can decompose formaldehyde, the main function of which is high-concentration and highly active negative oxygen ions. The picture below is a mechanism diagram for the removal of formaldehyde and benzene by negative ions. As we said above, the chemical formula of formaldehyde is HCHO, and the chemical formula of negative oxygen ions is O₂, after the chemical reaction between the two, negative oxygen ions destroy the chemical bonds of formaldehyde and oxidize it, thereby converting formaldehyde into harmless substances such as water and carbon dioxide. The same mechanism is used to remove benzene, which destroys and oxidizes the chemical bonds of benzene, thereby converting it into water and carbon dioxide.
Because many high-concentration negative ions artificially stimulated will also produce ozone, and ozone is harmful to the human respiratory tract. Therefore, with scientific innovation, light negative oxygen ions (LNOI) technology combines the ultraviolet spectrum in sunlight with the ozone removal of negative ions. While ensuring the concentration and activity of negative ions, it also removes ozone and further upgrades the value and role of negative ions. Therefore, compared with the simple negative ion decomposition of formaldehyde and benzene technology, light negative oxygen ions (LNOI) technology is obviously more advanced, more environmentally friendly, healthier, and closer to the people's needs for a better life.
