The main part of dust in dust plate automatic pressure type punching production line, according to the principle of aerodynamics design, structure parameters according to the results of wind tunnel test simulation implementation environment, processed into a certain geometry for corrugated, round, oblong, oval hole, used to reduce wind speed the flow of the wind, the maximum kinetic energy loss of wind flow, reduce turbulence wind, wind and dust to achieve. Wind and dust plate is an important part of Hunan. Made of SMC-FRP composite materials, titanium alloy, stainless steel, according to the principle of aerodynamics design, structure parameters according to the results of wind tunnel test simulation implementation environment, processed into a certain geometric shape, mostly round, oblong corrugated. So, the oval hole, to reduce the flow velocity of the wind, the maximum kinetic energy loss of wind flow, reduce turbulence wind, wind and dust to achieve. Wind and dust in coal yard according to meteorological conditions, coal particle diameter distribution, and geometric parameters, mechanical properties, experiment and optimization calculation of wind and dust plate to meet the geometry, set insulation on corrosion resistance, aging resistance, color, and other aspects of requirements for computer ingredients. After the composite process is made into SMC wind dust suppression board.
