Plastic alloy is different monomers in the polymer, based on the use of synthetic nano-materials and a variety of rare earth additives modified by special synthetic process made of homogeneous polymer with excellent low coefficient of friction, self lubrication maintenance, corrosion, abrasion, large capacity, anti-aging properties, dual Face products in the tri-state (dry, water states, oil-state) conditions the friction coefficient is small, but each state static friction coefficient difference is small. Mechanical properties of materials are stable at three games (force field, electric field, chemical field) effects. Product description MGB materials and design used for large heavy duty, corrosion is not easy to refuel or condition of major type of water conservancy projects. Such as radial gate trunnion bearings, large load sheave bearings, thrust bearings, spherical plain bearings, skateboard, slide gates, miter gate support bearings, wicket bearings. MGC materials are mainly used in some of the larger load bearing, skateboard or slider, thrust ring. MGD materials are mainly used in small and medium load bearing, skateboard or slider, thrust ring. MGE pressure pad material for dock doors, pier collision plate, low coefficient of friction, static friction coefficient is similar to a large heavy pan can be used for skateboarding. MGE material for the rope round hinges, rollers, gears, positioning wheel, walking wheel. MGC skateboard applies not only to ship slipway, and widely applied in bridge construction projects, pushing devices. MGA self-lubricating plastic alloy material has good performance, so was only a wide range of applications, you can refer to data comparison, I believe the project will have its own conclusions MGA engineering unit density g / cm3 1.14-1.2 maximum continuous operating temperature ℃ +145 minimum continuous operating temperature ℃ -45 Tensile yield strength MPa 110 MPa 125 Tensile strength Ultimate tensile elongation at break% tensile modulus of 20-30 MPa ≥3600 MPa ≥81 compressive shear strength Bending strength MPa ≥165 strength MPa ≥170 flexural modulus MPa ≥4000 impact strength (unnotched) KJ / m ≥550 Shore hardness D 68-80 coefficient of linear expansion 1 / ℃ 5.8-8.3 × 10-5 wear rate Mg / N? m 5.7 × 10-7 oil absorption rate of water absorption% ≤0.8% ≤0.05 limit PV value MPa.m / s ≥12 friction coefficient lubrication movement speed m / s MGA temperature ℃ using water lubricated conditions 0.05-0.16 0.03-0.05 -40 ~ + 100 on amphibious and underwater machinery, easy refueling, corrosive conditions.
