The pass rate of wooden furniture (wooden cabinets) products was 84.1%, and the content of hazardous substances detected in some products exceeded the standard.

A total of 270 kinds of wooden furniture produced by 266 enterprises in 15 provinces and municipalities including Beijing, Tianjin, Hebei, Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Shandong, Henan, Hunan, Guangdong, Chongqing, Sichuan, and Shaanxi were inspected. Wooden cabinet) products.

Spot checks found that more than forty kinds of products did not meet the requirements of the relevant standards, including 11 batches of formaldehyde emissions, soluble lead, soluble chromium and other harmful substances limit failed. For example, a batch of "Andia" bedside cabinets in Denghuang Furniture Factory in Shifang City failed to pass the formaldehyde emission, soluble lead, and soluble chromium items.

34 kinds of ceramic tile products failed

National supervision and random inspection showed that 34 of the 185 ceramic tile products did not meet the requirements of the relevant standards. It is reported that the water absorption rate is the percentage of the amount of water absorbed by the pores in the ceramic tile product. The lower the water absorption rate, the higher the product strength, the better the wear resistance and gloss performance, and the less prone to cracking or peeling.

The modulus of rupture and the strength of destruction are two main performance indicators for measuring ceramic tiles. Products that fail these two indicators are prone to cracking and breaking during use, which not only affects the decorative effect, but also may cause personal injury. Large deviations in size will affect the quality of construction and installation and reduce the engineering grade.
