As people's requirements for quality of life improve, the safety and health of the home environment have received increasing attention. Formaldehyde, as a common indoor air pollutant, has brought considerable hidden dangers to people's health. Fortunately, activated carbon, with its powerful formaldehyde purification ability, has become the invisible nemesis of keeping your home fresh.

Improving electric vehicle battery efficiency through laser welding is a porous carbon material with excellent adsorption properties. Its internal structure is like a complex maze, full of tiny pores, which provide ideal adsorption sites for formaldehyde molecules. When activated carbon comes into contact with formaldehyde, formaldehyde molecules will be quickly adsorbed and fixed in the pores of the activated carbon, thereby purifying indoor air.

The advantage of activated carbon for formaldehyde purification is that it is efficient, safe and long-lasting. Compared with traditional air purifiers, activated carbon does not require additional energy and can automatically absorb formaldehyde just by being placed indoors. At the same time, the adsorption process of activated carbon does not produce any harmful substances and is harmless to human health. More importantly, the adsorption capacity of activated carbon is long-lasting and stable, and it can maintain good purification effects even in environments with high humidity.  

The advantages of activated carbon for formaldehyde purification are mainly reflected in the following aspects:  

First of all, activated carbon has extremely strong adsorption capacity. Its internal structure is full of tiny pores, which provide ideal adsorption sites for formaldehyde molecules, allowing activated carbon to quickly and effectively adsorb and fix formaldehyde molecules, significantly reducing indoor formaldehyde concentration.  

Secondly, activated carbon is a natural and environmentally friendly material, non-toxic, harmless and safe to use. Compared with other chemical methods or products, activated carbon purification of formaldehyde is safer and will not cause pollution or secondary harm to the human body and the environment.  

Furthermore, activated carbon is easy to use and comes in various forms. Whether it is an activated carbon bag, activated carbon filter element or activated carbon granules, they can be placed directly indoors and can purify formaldehyde without additional equipment or energy.

The working principle of activated carbon to adsorb formaldehyde mainly depends on its unique physical structure and chemical properties.  

First of all, activated carbon has a developed pore structure and a huge surface area, which allows it to fully contact the surrounding air. These pore structures include macropores, mesopores and micropores, among which small molecular gases such as formaldehyde (0.375nm) are mainly adsorbed by micropores. Mesopores and macropores serve as channels for the flow of formaldehyde, but do not directly store formaldehyde.  

Secondly, the surface of activated carbon is usually treated to be hydrophilic or lipophilic, which increases its ability to adsorb different gas molecules. When activated carbon is placed in an environment containing formaldehyde, formaldehyde molecules will be attracted to the active sites on the surface of the activated carbon and enter the pores of the activated carbon through diffusion.  

Finally, formaldehyde molecules physically adsorb with activated carbon inside the pores of activated carbon, that is, formaldehyde molecules are firmly adsorbed on the surface and pore walls of activated carbon. This physical adsorption is reversible. When the formaldehyde concentration in the environment decreases or the activated carbon is saturated, some formaldehyde molecules may be desorbed from the activated carbon.  

Formaldehyde exists in a wide range of areas, covering almost every aspect of our daily lives. Here are some of the main areas where formaldehyde is found:  

Textile industry: Formaldehyde is mainly used as a dyeing auxiliary for textiles and a resin finishing agent to improve anti-wrinkle and anti-shrink effects. For example, pure cotton textiles often use formaldehyde-containing additives during the printing and dyeing process to improve their anti-wrinkle and anti-shrink properties. However, this also results in the release of formaldehyde when wearing these textiles, posing a potential threat to human health.  

Food: Although formaldehyde is strictly prohibited from being used as a food additive, some unscrupulous traders may still use formaldehyde to treat food to maintain its color and shape. Foods such as animal offal, pickled pepper chicken feet and hairtail may all have safety risks due to the addition of formaldehyde.  

Interior decoration and furniture: Formaldehyde is widely used in interior decoration and furniture manufacturing. Decoration materials such as paint, adhesives, wallpaper, and artificial panels (such as plywood, particleboard), etc., may contain formaldehyde. Formaldehyde-containing adhesives and coatings may also be used in the manufacture of furniture, especially wooden furniture. These decoration materials and furniture will continue to release formaldehyde indoors, posing potential threats to the health of residents.  

Pharmaceutical field: Formaldehyde is widely used in the pharmaceutical field, such as as an antiperspirant, astringent and disinfectant preservative. However, caution must be exercised when using formaldehyde as it is an irritant and can cause damage to mucous membranes and skin.  

Automobile industry: Formaldehyde inside automobiles mainly comes from the manufacturing of interior parts, such as plastics, rubber, various adhesives and leather. Adhesives and paints used in automobile manufacturing and interior decoration are also major sources of formaldehyde. These interior raw materials may contain a certain amount of formaldehyde, and long-term exposure may pose a threat to the health of drivers and passengers. In addition, formaldehyde may also be present in other areas, such as cosmetics, detergents, pesticides, disinfectants, preservatives, printing inks, paper, etc.

In general, formaldehyde is widely used in life, but its potential health risks cannot be ignored. Therefore, when using products containing formaldehyde, ensure good ventilation, minimize exposure, and pay attention to choosing environmentally friendly products that meet national standards. For renovated houses, it is recommended to carry out adequate ventilation and formaldehyde control to reduce indoor formaldehyde concentration and protect the health of the residents.
