Waterproof material pick toughness
Waterproof materials are often used in hidden renovation projects, and consumers often have difficulty visually seeing their quality problems. Because of this, waterproof materials are often hidden in the decoration. Experts said that the purchase of waterproof materials should be comprehensively examined from the aspects of tensile strength, elongation at break, and impermeability.
For waterproofing membranes, due to the tight connection between the application and the base layer, the stretching or cracking or deformation of the base layer directly affects or limits the use of the coil. Therefore, the waterproof membrane must have strong adaptability to the base layer. Experts said that when purchasing PVC waterproofing membranes, consumers can pull it by hand and feel that the higher the toughness of the coil, the higher the tensile strength, the greater the elongation, and the better the adaptability to the base layer. .
In addition, the reporter reminded consumers that if you purchase waterproof coatings, you must pay attention to their environmental performance. Waterproof coatings often include adhesives and colorants in their production. The reporter saw on the market that many building materials cities have water-based architectural waterproof coatings. Smoked environmental performance is better, consumers may wish to try.
Adhesive pick green degree
Adhesives are a kind of building materials necessary for home decoration, and many building materials themselves also contain adhesives such as plates, paints, and coatings. The quality of adhesives is directly related to the health of the home environment. However, in this inspection by the Bureau of Industry and Commerce, there were a total of 5 types of adhesives that were unqualified, and their quality problems were mainly due to excessive levels of formaldehyde and benzene.
The reporter learned from the National Building Materials Testing Center that the free formaldehyde content of the adhesive should be less than or equal to 1g/kg, and the benzene content should be less than or equal to 5g/kg. In the recent inspection by the Bureau of Industry and Commerce, Beijing's 100-year-old Xinyuan Trading Co., Ltd. produced a one-year, 2kg-per-barrel adhesive with a benzene content of 75g/kg, far exceeding the standard value.
Here, the reporter reminded consumers that they can use the “nose smell†method when buying adhesives. If the adhesive emits a strong irritating odor, then most of the harmful substances are excessive.
