The U.S. Consumer Product Safety Commission (CPSC) recently issued an updated research report that Chinese-made gypsum board will not be any short-term or long-term safety hazards caused by electrical system components.
Hurricane Katrina disaster in 2005, the United States facing a large number of housing reconstruction, builders, building materials distributors in accordance with U.S. standards imported from China some of the gypsum board. To the second half of 2008, with the gradual deterioration of the financial crisis, the U.S. media began a large number of reported fever humid areas of the coast of the United States, some families use domestic gypsum board, the house smell, some people nosebleeds, headaches and other symptoms, the metal devices and air conditioning system, black or rust, damaged houses, and health problems. Gave rise to the centralized proceedings of the U.S. consumer in the domestic gypsum board.
It is understood that the problem drywall electrical components, corrosion research report "The CPSC released in corrosion of electrical components for the gypsum board to expand the full study on the basis of the formation.
Storm since the beginning of China and the U.S. gypsum board proceedings, in addition to domestic gypsum board questioned the impact on human health, the U.S. media also reported that U.S. coastal fever humid areas, some families use domestic gypsum board, metal components of the house, especially air conditioning electrical parts in black or rust, bringing a huge security risk. To this end, the CPSC staff through inter-agency agreement with the U.S. Department of Energy's National Nuclear Safety Commission and tasked the Sandia National Laboratories (hereinafter referred to as "Sandia") Materials Science and Engineering Center for testing and research.
The report shows that Sandia to start this work in April 2009, initially carried out by the representative of the affected housing 6 outlet detection analysis, and draw the conclusions of the "short-term electrical safety is not affected" ; followed by further studies, Sandia simulation chamber accelerated corrosion test to simulate the corrosion problem drywall construction home appliance system components in the housing 40 years, the result is the collection components in the early detection of conclusions consistent. Based on these findings, the report therefore emphasized that the Further description of the electrical components is safe enough to withstand live in the housing site on real environment and long-term hydrogen sulfide simulation environment of the test.
In January 2011, the domestic gypsum board toxic, "said one had already been confirmed to be non-existent. Not only the relevant research institutions in China released study confirms that in the domestic gypsum board non-toxic, CPSC also announced the investigation report shows that the domestic gypsum board product quality and the U.S. media reported 11 people dead and has nothing to do, the gypsum board does not have an impact on health .
The release of the Sandia this authoritative report provides further proof of the domestic gypsum board no problem in terms of quality and environmental protection.
Sandia report in the local environment is classified as corrosive industrial environments, the formation of such an environment is local many years of industrial pollution caused by the problem, is not "dry wall". In addition, even in such an environment, Sandia has made it clear that the problem drywall home appliance system components do not build houses there are security risks, such as lead to potential risks, such as smoke, fire.
The report said, the CPSC staff has known fire or malfunction complaint tracking and investigation, "did not find any fire or fault wall-related problems stem directly caused by corrosion.
