AHF antifriction polymer composite based on polytetrafluoroethylene, sopolimeriv ethylene and tetraftoretylenu bridges and other fluorine polymers, modified carbon fibers and other fibrous fillers and dispersed. Number p / Key indicators of material A G F 1 density, kg/m3 2000 ... 2400 2 Strength, MPa, in tension 12 ... 17 shrinkage 30 ... 33 3 modulus, MPa, in tension in 1000 ... 1200 compression 700 ... 800 4 The elongation at break,% 6 ... 30 5 coefficient of thermal expansion (x10-6) at 273 ... 523 K, K-1 66 ... 68 6 Thermal conductivity at 273 ... 523 K, W / (mK) 0.37 ... 0.43 7 Hardness HB, MPa 50 ... 60 8 resiliency, kDzh/m2 15 ... 40 9 The intensity of wear (x10-7), mm3/Nm at ultimate load 1.0 ... 30 moderate loads 0.8 ... 10 10 Coefficient of friction ultimate load 0.1 ... 0.3 moderate loads 0.06 ... 0.1 AHF is characterized by high durability and chemical resistance, low coefficient of friction. Details of the material AHF (sliding bearings, sealing rings, face seals, cage, support bearings) are used friction equipment for different purposes. This achieved a high durability and reliability of equipment, saving lubricants, reducing metaloyemkosti products and reduce the cost of repair and maintenance of vehicles, as well as the regeneration of catalyst chemical industries. For durable sealing material AHF prevail in 3 ... 10 times materials companies of Russia - ftorlon-4, F4K20, AHFM, AFH-5M, F4S15, AH-1500S05, 2P-1000, Kaprolon-B, as well as 3 ... 5 times material foreign companies «Harlok», «Merkel», «Dikson», «Ynelard». The technology of producing products with material AHF without additional machining. |
