Little common sense in home improvement
1. What is home improvement?
Home improvement environmental protection refers to indoor air quality indicators after decoration and decoration, which meets or exceeds the national environmental protection testing standards. It mainly includes physical, chemical, biological and radioactive indicators.
　
　　 2. What does it mean to say "home improvement pollution"?
The materials used in interior decoration and decoration emit harmful and toxic pollutants and pollute the indoor environment. This kind of indoor pollution from the decoration itself is called home decoration pollution. If the content of pollutants in the home decoration is too high and cannot be solved for a long time, it will cause physical discomfort and affect health.
　
　　 3. Briefly introduce several major home improvement pollutants
According to the use of construction, decoration and furniture materials in China, the main types of indoor household pollutants are as follows:
formaldehyde
Benzene: benzene, toluene, xylene
Total Volatile Organic Compounds (TVOC)
Free toluene diisocyanate (TDI)
Soluble heavy metals such as lead, cadmium, chromium and mercury
　
　　 4. The source of most home improvement pollution
Mainly three aspects, the building itself, the decoration materials and the new furniture purchased.
Formaldehyde contaminants are found in most decorative materials and furniture. Such as: inferior wood-based panels, adhesives and substandard coatings.
Benzene is present in organic solvents and various paint thinners of various building materials, and is also present in a large number of non-standard waterproof materials.
Materials containing total volatile organic compound (TVOC) contamination are paints, latex paints, and the like.
Toluene diisocyanate (TDI) contaminants are mostly found in polyurethane paint products.
Paints and adhesives containing heavy metal contaminated materials.
Radioactive materials contained in marble floors and stone.
　
　　 5. Is home-made pollutants the root cause of illness?
Home-made pollutants can cause illness, but there are many reasons for people to develop diseases. Home-made pollutants in the newly renovated houses, the content is too high, can not meet the national new environmental standards, and long-term unresolved, it will significantly affect the health of the body.
However, experts pointed out that there is still no scientific evidence that a certain disease is caused by indoor air pollution. Therefore, it is more important and effective to prevent air pollution from exceeding the standard than to investigate responsibility afterwards.
