Completely open the coat of interior decoration pollution

Buy a house decoration is to give families a better life. While enjoying this wonderful life, you need a healthy body. Unreasonable decoration, accompanied by poor decoration and indoor pollution, seriously affected people's health and quality of life. Come here today and take a look at the pollution of the indoor environment. I hope everyone can live a happy and healthy environment.

a) Chemicals. Mainly from the decoration, furniture, toys, gas water heaters, insecticide sprays, cosmetics, smoking, kitchen fumes, etc., including toluene, xylene, ethyl acetate, toluene, diethyl cyanate, formaldehyde and other volatile organic compounds and NH3, CO, CO2 and other inorganic compounds;

b) Physics. Mainly from noise, electromagnetic radiation, light pollution, etc. generated by outdoor and indoor electrical equipment;

c) Biological class. Mainly from parasites in carpets, plush toys, bedding and other bacteria such as maggots. At present, the main pollutants in urban office buildings and family homes are buildings, decorations and furniture.

1, decoration design is not reasonable

Excessive use of the same material in the room, such as the laying of laminate flooring on a large area, can cause excessive formaldehyde. Although many decoration materials claim to meet national standards and are "green" and "environmental" materials, they can only show that their harmful contaminants are minimized and not completely absent. Therefore, if they are used in a limited space, Then the concentration of toxic pollutants will increase substantially, and then exceed the standard and cause pollution.

2, poor construction technology

In the construction process of interior decoration, when cement is used, it is impregnated with ammonia admixtures, adhesives used for tiling, incisions made of plywood, edge-sealing of furniture, and coating of paint, etc. These will bring varying degrees of indoor air pollution. . In addition, the use of adhesives containing large amounts of free formaldehyde during construction will make it difficult for volatile gases to evaporate, which will cause long-term air pollution.

3, poor quality decoration materials

In the interior decoration process, many decoration materials, especially man-made boards, contain more harmful substances such as naphthalene, phenol and formaldehyde, or harmful gases. In addition, other auxiliary materials such as additives, adhesives, and putty powder are also the main sources of indoor gas pollution.

The result of a random inspection of interior decoration materials by the national health, construction, and environmental protection departments found that 68% of the materials contained toxic gas pollution. Once these materials enter the living room, they can cause more than 30 diseases such as respiratory tract, digestive tract, neurology, vision, vision, and high blood pressure, and the release period in the room is longer.

1, CO

CO can combine with hemoglobin in the blood to form carboxyhemoglobin, prevent the combination of oxygen and hemoglobin, reduce the ability of the blood to transport oxygen, cause tissue hypoxia, and cause various metabolic disorders of the organism.

2, formaldehyde

Formaldehyde is a recognized source of allergy. A large amount of formaldehyde present in the decoration materials is a strong carcinogen, and its effects on the human body are mainly manifested in abnormal olfactory sensations and have a strong irritating effect on the skin and mucous membranes. When the content of indoor air reaches 0.12mg/m3, there will be odor and discomfort; when it reaches 0.50mg/m3, it will cause tearing; when it reaches 0.60mg/m3, it will cause throat discomfort or pain; when it reaches 30mg/m3, it can immediately lead to death. Long-term low-dose skin contact can also cause chronic respiratory diseases and dermatitis and other allergic diseases, but also lead to abnormal lung function, liver function, and immune function.

At present, formaldehyde is a raw material for the manufacture of synthetic resins, paints, plastics, and man-made fibers. Materials used in interior decoration or furniture, such as plywood, blockboard, medium-density fiberboard, chipboard, wall coverings, wallpaper, chemical fiber carpets, paints, coatings, adhesives, etc., all contain formaldehyde to varying degrees or can be hydrolyzed to formaldehyde. Chemical substances. These residual or decomposed formaldehyde will gradually release into the surrounding environment, with the longest release period of up to 10 years.
