NFJ metal aggregate wear-resistant materials

NFJ metal after steel fiber aggregate is, another modern new building materials. The material for the hard metal, shape of the particles, mixing with ordinary portland cement, laid in just built into the concrete surface to achieve surface hardening purposes. The wear resistance of the concrete surface is significantly improved, but also makes the oil, compressive, flexural, tensile, impact resistance is enhanced, and can not afford to ash, greatly improve the working environment, is ideal for today's concrete surface hardening material . NFJ metal aggregate by double high composite rust treatment, with a permanent anti-rust. Construction is very convenient, good surface after curing the perception, the use of surface engineering durability. Has passed technical appraisal, and won the national invention patents, the State Science and Technology Commission and was also rated as the national scientific and technological achievements, state-level new products, won the China patent new products Silver, Gold, Ministry of Science and Technology Progress Award and many other awards. This product is a national initiative and more than similar foreign products, after nearly a decade of research and history, the products have been formed from NFJ1 to NFJ6 complete series, to meet a variety of usage requirements. ● withstand heavy-duty use of premises, often friction injury in place to withstand heavy trucks, forklifts and other places to withstand frequent DRUM continue to produce high-impact properties to withstand long-term accumulation of heavy cargo processing and production of sophisticated technology required to place the dust of place bear large machine tools, machinery and equipment requirements for anti-static weight of place, do not get angry place oil spill occurs, the places are required for an oil slip resistant places ● Scope warehouses, terminal handling area, machine shops, aircraft parking apron, Garage , parking lot, fuel repository, channel ground, mining leavened trough, bridge, reservoir spillway, energy dissipation pool, loading ramp, military enterprises, textiles, frozen warehouses, automotive industry, electronic industry, highways and so on. ● Features / Benefits after completion NFJ metal aggregate wear-resistant flooring has the following characteristics: high wear resistance, corrosion resistance permanent anti-static, no spark ● Specifications wear (metal aggregate Only NFJ have this feature!) weight wear rate <0.1% (ball method) per unit area of ??the wear 0.012 g / cm 2 (gear method) abrasion resistance than silicon carbide, artificial marble surface layer is 10 to 25 times more common ground. Compressive strength 3d 75.3MPa 7d 75.4MPa 28d 100.2MPa flexural strength> 11.5MPa (not broken) Tensile strength 3.9MPa Hardness 45 (rebound value, slag cement is 425), 10 (mineral feet). Youpao oil resistance without reducing the strength of three years, oil seepage <0.3mm. (Including impermeability) Impact energy 0.19J (small particles) shrinkage value -0.751 × 10-3 (210d) rust-resistant aggregate standard salt corrosion test, 42d natural potential positive constant, stable value + 50mv (SCE) maximum +120 mv (SCE). Cement test body, 5% NaCl solution immersion, 2 years and 3 months without rust, no wet bursting. Non-slip concrete floor with in general. Fire resistance is not angry, no explosion (in accordance with GB50209-95 national standards). Anti-static test surface leakage resistance in the range of 105 to 106.
