Silicon carbide, silicon carbide slag manufacturers Henan factory http://www.ayrjjscl.com/ Anyang Ruijin Metal Materials Co., Ltd. was established in 2005, mainly engaged in industrial silicon, silicon desulfurizer increased, desulfurizer, ferrosilicon, silicon carbide. Since its inception, done by "honest, pragmatic, innovative, pioneering" development purposes and "people-oriented, and create a win-win" business philosophy, market opportunities, and strive to enlarge and strengthen the company's sales network. Silica fume too little content in the concrete, concrete performance improvement is not, but content too much, then the concrete is too sticky, difficult construction, and shrinkage deformation, frost resistance is poor, and therefore, when silica fume, should find the optimal dosage for best results. Under normal circumstances, the content is more than 10% satisfactory results. Proper dosage is generally used fume silica fume, cement and aggregate nature of the species selected according to several silica fume content, such as 3,5,7,10%, etc., forming concrete specimens, drawing R-SF (intensity - silica fume) curve is determined. The adoption of modern management concepts, adhere to the quality of survival, integrity and development, gradually boarded competing platforms globalization. We still insist on "customer service, for the benefit of employees, joint development, contributing to society" business philosophy, and constantly enrich the "technology first, quality-oriented, the pursuit of excellence, integrity future" corporate culture connotation, and actively participate in market competition, rely on good faith make friends, rely on services to promote feelings of faith to create value for customers, providing our customers with high quality and reliable products and dedicated services.
