2nd quarter of 2009, Shaanxi Provincial Quality and Technical Supervision of the province-wide production and sales of cement, construction insulated sleeve pipe, PVC pipe, PVC pipe fittings, stainless steel, aluminum, plywood, , wood flooring, doors and other products 9 regular random inspection. Upon examination, 513 batches of 367 batches of qualified products, 71.5% pass rate. Among the most prominent man-made board problems, nearly 8 percent failed. It is understood that all wood-based panel sample distribution enterprises in Shaanxi Province, collected a total random sample of 80 batches tested, 17 lots, 21.2% pass rate. Problem is mainly formaldehyde emission, the surface bonding strength, bending strength and other projects failed. Surface bonding strength of products prone to failure stratified, open plastic and so on; lateral bending strength of the project can easily break the products failed to make products difficult to guarantee the overall strength. Formaldehyde emission failure extremely harmful to human health, human eyes, respiratory stimulation significantly, the WHO has classified formaldehyde as carcinogenic one. Relatively good quality wood flooring, 85% pass rate, the main problem is the surface wear, thickness swelling, bending strength of the project failed. The spot checks found that the quality of cement is relatively reassuring. The total of 158 manufacturing enterprises across the province sampling, sampling 166 batches, 154 batches of qualified, in-kind quality standards was 92.7%. Problems are mainly three days flexural strength, compressive strength of 3 days, 28 days compressive strength, 28-day flexural strength, stability, chloride project failed. Flexural, compressive strength of substandard building construction will seriously affect the quality and stability of destroying the building easily lead to failure stress, severe cracking will lead to buildings, landslides and other accidents, excessive chloride ions will be building in corrosive to steel. In addition, the building insulated sleeve pipe overall pass rate of 60%, the main problem is the minimum thickness, compression performance, identification failed. PVC pipe 48.5% overall pass rate, the main problem is the tensile yield strength, density, minimum wall thickness, average diameter, 20 ? hydraulic pressure test failed. PVC pipe overall pass rate of 59.3%, the main problem is mainly the minimum wall thickness, the average diameter of socket, bearing the mouth for an average diameter, density, socket depth, oven test failure. Stainless steel tube 58.3% overall pass rate, the problems are mainly manganese, nickel, chromium and other chemical elements than the standard specification. The overall passing rate of 93.3% aluminum, aluminum is mainly a problem in the quality of surface properties, chemical composition of the project failed. Doors pass rate was 88.3%, mainly sandbags impact performance, solid wood door using wood species identification name of the other projects do not meet. It is reported that, in Shaanxi Province Quality and Technical Supervision has instructed the municipal quality and technical supervision departments in strict accordance with the Product Quality Law and other relevant laws and regulations, failure of product quality of the sample companies and the law, and urge enterprises deadline for correction. Quality of products and will continue to track the above checks, to promote the industry continuously improve the overall quality level, to create confidence for consumers satisfied consumption environment.
