Magnetic powder PGA -1 for moving magnetic

Magnetic powder PGA -1 Main features The powder PGA -1 (TU 1479-002-12300291-2005) is intended for use as rolling magnetic core drilling brakes type T-EP 45-1 (TU 16-538.186-80). Is a powder of spherical form with metal base and surface membrane-based solid solution A1 in Re. Available since 1996, instead of powder PR-W1 (TU-14-1-4430-88). The properties of the powder: The powder has a high corrosion resistance that prevents sintering and pelletization in operation,dысокая resistance of this powder to oxidation (fourfold compared to the previously unreleased PGR-1) ensure long-term operability of the powder in the most difficult climatic conditions. Powder PGA-1 has high wear resistance and resistance to abrasion. The chemical composition of the base corresponds mark PGR-1. In free state pouring 3,8 g/cm 3, the content of aluminum in the protective sheath to 12 mass %, color - dark grey, when operation changes a little-micro-framework - 50 kg/mm 2, shell -180 HR/ADM 2, which provides not less than 4-fold increase wear powder Fractional composition: type 1: fraction 160-315 μm is not less than 80 %, type 2: Fraction 160-400 not less than 90%. Evaluation of the performance properties of the powder PGA-1 in the composition brake TEP 45 N1. The table shows the main characteristics of the brake TEP 45 N1 with powders PGA-1 and PGR-1 when the mass of the powder 25 kg: (kgf*m) and the maximum braking torque with a weight of 22 kg Braking torque Passport PGR-1 PGA - 1 Maximum 6500 6831 7699 Rated 4500 5140 5800 The residual 30 17.8 26 Max. with a weight of 22 kg 6500 6130 7005 Specifications brakes when using powder PGA - 1 is less sensitive to the reduction of the mass of powder during operation than when using AHC -1. Operational time: guaranteed physical durability of 1200 hours at 25 % drilling, 10 % slope. Packing: sealed containers weighing 10 kg (net).
