The air purification system price [air purification system] Huasheng / full range of formaldehyde from the interior decoration and decorative materials. Used as interior decoration of the wooden man-made sheet of plywood, block board, medium density fiberboard and particleboard, adhesives used in the processing of the urea-formaldehyde resins and phenolic resins, the main raw material is formaldehyde, urea, phenol and other accessories, sheet residues not involved in the reaction of harmful substances such as formaldehyde will be gradually released into the surrounding environment, forming the main body of formaldehyde in indoor air, thus causing indoor air pollution. Indoor furniture manufacturer in order to pursuit of profit, the use of substandard man-made sheet, use of poor quality glue bonding the veneer material, manufacturing process is not standardized, very high levels of volatile organic compounds. Yokohama National University in Japan show that the period of the release of formaldehyde in the artificial board 3 
 - 15 
 Years. New furniture, the decoration of the wall the ground should be using the binder. Any extensive use of the binder of the link, there will be the release of formaldehyde. In addition, the wallpaper, synthetic carpet, plastic floor tiles, foams, coatings, paints and diluted material also contains a certain amount of formaldehyde. 



 Formaldehyde is a colorless irritating gas, the most sensitive human health is the sense of smell and stimulate, especially in the intima of the eyes, throat, skin irritation, the greatest effect. When the content of formaldehyde in the air for 011 
 mg / m3 have odor gives rise to discomfort. 


 (U.S. EPA Indoor Air Quality Department that the long-term exposure to indoor formaldehyde emission reach 011 ppm will produce discomfort); reach 015 mg / m3 
 Can stimulate the eyes to cause tears: 016 mg / m3 caused by throat discomfort or pain; with the concentration can also cause nausea, vomiting, cough, chest tightness, shortness of breath; greater than 615mg / 
 m3, can cause pneumonia, pulmonary edema, injury, or death. Long-term exposure to low concentrations of formaldehyde (01017mg / m3 ~ 01068 mg / m3) 
 Can cause chronic respiratory diseases, menstrual disorders, pregnancy complications, caused by neonatal physical reduce chromosomal abnormalities, and even lead to nasopharyngeal carcinoma. High concentrations of formaldehyde has a poison on the nervous system, immune system, liver, long-term exposure to higher concentrations of formaldehyde acute mental depression. Of formaldehyde There pathogenic and carcinogenic effects. International Agency for Research on Cancer has recommended that it be classified as suspected carcinogens. 

 BTEX 


 Benzenes in organic solvents for a variety of architectural decoration materials abound, such as a variety of paint and coatings additives, thinners, and some waterproof material and so on. Low-quality furniture will release benzene and other volatile organic compounds. Wallpaper, vinyl flooring, plywood and paint is an important source of aromatic hydrocarbons pollution in indoor air. These building and furnishing materials in the room will continue to release harmful gases, the release time of up to 1 
 Years; the market of decorative materials, use the release of harmful gases products are also many. With special aromatic benzene is a colorless liquid, is a kind of indoor volatile organic compounds. Inhalation of high concentrations of benzene vapor can cause central nervous system suppression of acute benzene poisoning in a short time, the light dizziness, headache, nausea, chest tightness, fatigue, confusion and other phenomena: In severe cases, coma and even respiratory, circulatory failure and death. Long-term exposure to low concentrations of BTEX can cause chronic poisoning, dizziness, insomnia, listlessness, loss of memory, nervous exhaustion, but also the performance of the stimulating effect on the skin, eyes and upper respiratory tract, and platelet, leukopenia, severe cases can bone marrow function disorder occurs, and also have some impact on reproductive function. Benzene experts have confirmed a serious carcinogen.
