Shanghai Municipal Administration of Industry and Commerce recently announced the city circulation of synthetic resin emulsion interior wall paint and wood coatings quality monitoring results, polar bears, Macao special, modern, charms Korea brands such samples were detected excessive formaldehyde serious harmful substances. In this regard, the experts suggest that consumers should pay attention to buy paint brands, to the operators ask for a valid certificate purchase invoice and construction manual, be careful to buy.
Shanghai Industry and Commerce Bureau, said the monitoring sampling four regions of the city's Jiading, Jinshan, Minhang and Pudong New Area, building materials supermarket and integrated market, mainly for health consumers are generally more concerned about environmental issues, and according to the national mandatory standards select projects that have a direct impact on the health of people sampling samples were tested, including volatile organic compounds, benzene, formaldehyde, etc..
The monitoring results show that the the detected failed project is mainly reflected in the free formaldehyde resistance, scrubbing and ratios. The monitoring results also showed that building materials supermarkets pass rate is significantly higher than the integrated market, the quality of the wood coatings situation is significantly better than the synthetic resin emulsion interior wall paint, wood coatings all qualified 15 batches, 16 batches of synthetic resin emulsion coatings for interior wall is deemed to have failed.
The free formaldehyde indicators is a very important safety quality indicators, which is directly related to human health and safety of consumers. Use of substandard products, not only affect the air quality of the indoor environment, and consumers' long-term exposure to cause chronic respiratory diseases. Monitoring four batches of polar bears, Macao special, modern, charms Korea brand samples free formaldehyde content exceeded the phenomenon, which, three batches of the measured values in the the 200mg/kg above (standard value ≤ 100mg / kg), higher than the standard.
In addition, the detection process, also found that many products scrub resistance and ratio of the project is lower than the national standard. A total of 15 batches failed, scrub resistance the seven batches ratio unqualified batches of six, two indicators also failed. Among them, 12 batches of scrub resistance measured in the 200, seven batches of scrub resistance measured value is less than 50 times, far lower than the current standard.
According to reports, scrub resistance and the ratio of two indicators technical indicators of the assessment of the performance of interior wall paint, scrub resistance reflects the adhesion of the coating to the substrate as well as anti-washing capacity. The ratio reflects the elimination of the ability of the substrate color of white and light-colored paint, the two indicators failed, will lead to latex paint does not scrub masking effect, which lack the protective and decorative functions. Washability indicators based on national standards, interior wall paint qualified products less than 300, First grade of not less than 1000, at least 5000 times superior product.
