    In interior decoration, people generally pay attention to benzene pollution in coatings In fact, formaldehyde is the number one killer in home decoration It exists in a large number of coatings and adhesives, mainly from coatings and adhesives based on polyaldehyde resin, melamine formaldehyde resin, phenolic resin and other additives Experts said that formaldehyde is a colorless and irritating toxic chemical, which is a strong carcinogenic and teratogenic substance determined by the World Health Organization (W.H.O) Long term inhalation of formaldehyde can cause respiratory system, nervous system, reproductive system and other diseases Formaldehyde is also the main cause of neonatal deformity, childhood white body disease, memory and intelligence decline of teenagers The Modern Express reported on September 30, 2002 that there was a family in Nanjing The 70 year old mother and her 40 year old son lived in the new house for four months and seven months, and then they were sick and admitted to the hospital They had leukemia after preliminary examination However, the indoor air test found that the formaldehyde exceeded the standard by 21 times, and the mother and son became serious victims of indoor decoration pollution How long is the residual time of formaldehyde after indoor decoration? China's epoxy industry online ( - e.cn) reporters consulted the relevant information The indoor and outdoor concentrations of formaldehyde in three different types of buildings were tested and compared at 2 weeks, 8 months and 10 years after the completion of the project The results show that the indoor concentration is 74-160 times higher than the outdoor concentration in 2 weeks, 43 times higher than the outdoor concentration in 8 months, and 6 times higher than the outdoor concentration in 10 years (48 μ g / m3) They think that the long-term residual formaldehyde mainly comes from plywood, chemical fiber board and other wood products (medium glue) As for the prevention of formaldehyde injury, the reporter learned after interviewing experts that from the perspective of use: first, to purchase coatings and adhesives based on epoxy resin and other materials and additives, this product and plywood using this kind of adhesives do not contain formaldehyde; second, to minimize the use of plywood, chemical fiber board and other wood products and adhesives to reduce pollution sources; third, to use formaldehyde Decompose and isolate products, such as micro glue formaldehyde elimination, so as to decompose or shield formaldehyde; fourthly, dry and dilute pollution sources as long as possible after decoration; fifthly, plant indoor flowers properly to absorb part of free formaldehyde.
