Henan province product quality supervision and inspection institute refractory 2013 selective examination results
Secco products instrument in henan province quality technology supervision bureau official website news reported recently refractory province product quality supervision and inspection results, one batch product quality does not accord with a standard to ask.
In the supervision and inspection sample of zhengzhou, luoyang, pingdingshan, xuchang, nanyang 5 municipalities and gongyi, 1 was made pioneer (city) 23 companies 35 batch production of refractory products. According to "2013 years of refractories of henan province product quality supervision and inspection regularly implementation plan", the mass fraction of refractory chemical composition, porosity, bulk density, true density, density, bending strength, compressive strength at room temperature under normal temperature, heating permanent linear change, rul starting temperature, creep rate, high refractoriness, high flexural strength, residual quartz, coefficient of thermal conductivity, thermal expansion rate and the thermal shock resistance of 16 projects for inspection.
After sampling inspection, there are 34 batch products accord with a standard to ask. Gongyi city yulong silica refractory material industrial co., LTD. A number of times (RG - 95-95) do not conform to the requirements of the standard, involving the room temperature compressive strength and porosity project.
Henan province pledges inspect bureau says, has instructed the relevant, straight pipe of the provincial-level pioneer (city) of quality and technical supervision departments in accordance with the relevant laws and regulations, for the inspection of the unqualified product and its production enterprise for processing in accordance with the law.
