The dust-proof tree grate and tree pit protective net for municipal greening is not only a glass fiber reinforced plastic tree grate, but also a kind of plate-shaped material with many spaces, which is composed of glass fiber, resin, calcium powder, aluminum powder and color paste. It is usually used for municipal construction or road greening projects, with flexible and diversified specifications and sizes.
Quality judgment of the grate: there should be fiberglass within 2mm of the surface of the grate. The content of the fiberglass determines the strength of the grate. It is also necessary to pay attention to whether there are air holes and dry wires on the side of the grate. If there are air holes and dry wires, it means that the resin content is too little and the resin is not saturated. This kind of grate cannot be used. The surface of the grate with qualified quality It is a resin layer, which is easy to crack when it is out of mold and in daily use. The crack directly affects the service time of FRP grate.
Measurement of the specification and size of the grating: measure with a steel tape with an accuracy of 1mm, divide it into four parts on average along the width direction of the grating, and take the average value of the three measurement results; divide it into four parts on average along the length direction of the grating, and take the average value of the three measurement results; measure the thickness of a grid with a vernier caliper with an accuracy of 0.02mm, and take the average value of the four measurements.
The size of the whole dust-proof grid is mainly 1.22 * 3.66 and 1.220 * 4.04 (unit m). Different diameters of tree pits and trees require different sizes of grid. The installation personnel can cut according to the needs. When transporting the grate, the bottom of the vehicle and the ship shall be flat, and the long-distance transportation shall be bound firmly to avoid falling.
