Decoration materials can also produce pollution? Look at these materials that are prone to indoor environmental pollution, you must know!
1. Choose artificial wood materials. Due to the limitation of processing technology and the influence of differences in the quality of adhesives, the amount of formaldehyde released in many artificial wood panels circulating in the market has seriously exceeded the standard. When purchasing, pay special attention to the following items:
a. Artificial wood boards should be produced by regular manufacturers, with the quality appraisal certificate of the quality inspection department or the manufacturer’s mark, such as observing the back of the blockboard or 30mm from the edge of the board, whether there is a clear and non-fading number print, the content includes Category, production date, manufacturer code, inspector code, E0 or E1 grade, etc. It should be noted that it is best not to use miscellaneous wood core boards. These boards are put together with small pieces of miscellaneous wood, which contain the most glue, and most of them are not up to standard.
b. Use your nose to ask about the taste of the board. Friends can also conduct actual measurements by themselves. Smell the core of the horizontal board. If the smell is very pungent and the eyes feel uncomfortable, it is a substandard product.
2. The purchase of interior wall coatings. Qualified interior wall paint should be a safe and non-toxic building material. Unqualified paint may contain harmful substances. When purchasing paint, you should pay attention to the following items:
a. The quality and environmental protection performance of imported brands are relatively guaranteed, such as Dulux, Nippon Paint, Laiwei, Giraffe, Megasway Paint, etc. The domestic paint products such as China Resources are also good. When purchasing paint, you must go to a designated brand store. In addition, real brand agents have a series of supporting documents.
b. Check whether the color of the paint in the container is dark, whether there is agglomeration of deposition plates; whether there is colloid precipitation on the surface, whether there is freezing or moldy deterioration.
c. Brush the paint on the wall and touch it with your hands after drying to see if there is any powder falling off.
d. Is there any special pungent smell in the nose?
3. The choice of paint for wood products. The most commonly used coating materials for wood products are all kinds of paints, and paints are a well-known source of indoor pollution. When purchasing, you should pay attention to the following items:
a. Friends, it is best to buy environmentally friendly paint when purchasing. At present, some domestic companies have developed environmentally friendly paints, which do not use benzene-containing thinners, have less pungent odor, and evaporate faster, which is relatively environmentally friendly.
b. When purchasing paint, lift the oil drum and shake it. If there is a rattling sound, it means that the solid content is small, the thinner is too much, and the harmful components are large. The environmentally friendly paint of a regular manufacturer can hardly hear the sound when it is shaken.
4. Selection of stone materials. Stone has won the favor of the market because of its wonderful finishing effect and the visual experience of being integrated with nature, and has become one of the leading products for architectural decoration consumption. When a large area of living room is decorated with natural stone, the following points should be paid attention to when purchasing: Ask the merchant for the certificate of radioactivity and harmful gas indicators, pay attention to check which type of product is marked on the stone package as A, B, or C, and whether the inspection report has the CMA mark or ask a professional inspection agency to inspect it. In addition, the following identification methods should be used to see whether the stone is environmentally friendly.
a. The radioactivity of the stone can be qualitatively judged from the color. The radioactivity from high to low is red, green, flesh red, off-white, white, and black. Therefore, in order to meet the requirements of green decoration, it is recommended that you choose stone with low radioactivity.
b. Listen to the knocking sound of the stone, the knocking sound is clear and pleasant, indicating that the internal structure of the stone is uniform without microscopic cracks, and the harmful substances such as radium contained in it are relatively reduced; on the contrary, if the knocking sound is rough, it means that there are microscopic cracks inside the stone Or the fine veins become loose due to weathering, and the harmful substance radon produced during the decay process of the internal radium will be released quickly and in large quantities, which will cause certain harm to the human body.
5. There are standards for purchasing putty. Putty is used in a large amount in paint construction. The coagulation material of putty is glue. The quality of putty directly affects the indoor air quality. When purchasing putty, you should pay attention to the following items:
a. The outer packaging has a clear and non-fading number stamp, which includes category, production date, implementation standards, etc. The quality should meet the requirements of the national standard “Indoor Construction Putty”, and a test report is required.
b. 107 glue contains harmful substances. The relevant national regulations have explicitly prohibited the use of 107 glue in home decoration.
c. In order to achieve the effect of green decoration, it is recommended that you buy qualified products and not be greedy for cheap. According to market research, the price difference of finished putty is also very large. Generally, the price of qualified putty is more than 1.0 yuan/kg, the price of alkali-resistant and water-resistant putty is about 2.0 yuan/kg, and the price of inferior putty is below 0.5 yuan/kg.
