Problems solved by technology
[0003] In order to overcome the defects existing in the existing wind-shielding and dust-suppressing boards, one of the objects of the present invention is to provide a one-time forming wind-shielding and dust-suppressing boards, the fiber bundles in the fiber fabrics of the wind-shielding and dust-suppressing boards are continuous, and the fibers The bundle is covered with a resin matrix, so that the wall of the ventilation hole forms a round hole that cannot be penetrated by rainwater, which solves the problem of water penetration resistance, thereby improving the service life of the windshield and dust suppression board

Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] The present invention is a one-time forming wind-shielding and dust-suppressing board. The wind-shielding and dust-suppressing board 1 is designed according to the year-round dominant wind direction and wind load requirements of the use environment. 1 and angle β, angle β 1 The angle of is defined to obtain the length of the left and right choke surfaces. Angle α and Angle α 1 It is formed by the left choking surface 102 and the positive choking surface 101, the angle β and the angle β 1 It is formed by the right wind-blocking surface 103 and the positive wind-blocking surface 101. When the included angle α and the included angle β are the same, it is a symmetrical trapezoidal structure. The included angle α and the included angle β 1 When the angles are different, it is an asymmetric trapezoidal structure, and the included angle α 1 When the angle...

This invention discloses a once formed wind shield dust suppressing board and its mould and manufacturing technique for processing. The board is one body structure, and the mould is also the structure, modular surface type of the mould is correspondingly same to type of wind shield dust suppressing board. Ortho break wind surface, left and right break wind surface, left and right installing surface are set on the board, air hole are set on the ortho, left and right break wind surfaces, mounting holes are set on left and right surface. The left surface is on left of the ortho surface, left installing surface is on left of left surface, the right surface is on right of ortho surface, and right installing surface is on right of right surface. Included angle alpha is formed by the ortho and left wind shield surfaces, and the included angle is 95 degree to 150 degree, included angle beta is formed by the ortho and right break wind surfaces, and the included angle is from 95 degree to 150 degree. The fiber assemblies in fiber tissue of the board are continuous fiber, and its continuity doesn't be cut off, so the mechanical properties of the board are improved effectively.
Description
technical field [0001] The invention relates to a production mold for one-time molding of a wind-shielding and dust-suppressing board, and a processing method for one-time forming and processing of a wind-shielding and dust-suppressing board using resin as a composite material matrix. The wind-shielding and dust-suppressing board of the invention is impregnated formed of fibers. Background technique [0002] The wind and dust suppression board plays an important role in protecting the environment, preventing dust, and reducing losses caused by wind and sand. It is widely used in freight yards, coal mines, coal yards, construction sites and other places. There are roughly two types of base materials for windshield and dust suppression panels currently used. (1) It is made of a steel plate. Considering the ventilation requirements, it is generally necessary to carry out a second processing on the steel plate, that is, to drill through the ventilation holes, and the drilling r...
