According to the different forming process, FRP grid can be divided into extruded FRP grid and molded FRP grid. The molded FRP grid is a kind of plate with two-way mechanical characteristics, which is

The service life of GRP grid plate is greatly related to the use and application environment of raw materials. Let's have a detailed understanding:

The relationship between the service life of GRP grid plate and raw materials:

Because fiberglass grid is a composite material combining fiberglass and resin, the function of fiberglass grid depends on the advantages and disadvantages of the two raw materials used: the chemical properties of fiberglass grid mainly depend on the function of matrix resin, while fiberglass is the support of fiberglass grid, so the mechanical functions of fiberglass grid, such as strength, hardness, flexibility and so on, are taken It depends on glass fiber. Although the properties of the two raw materials are different, they should bear their own responsibilities, but they also have influence on each other rather than absolute. For example, the shear strength and zigzag strength between glass fiber reinforced plastic layers are related to the resin with mechanical function, and they are an important factor affecting each other.

The relationship between the service life of GRP grid plate and the service environment:

1. In the natural environment, the temperature should be kept at a fairly stable temperature. The minimum temperature that the FRP grid can bear is - 80 ° C, and the maximum temperature is 80 ° C. if it exceeds this range, it will be deformed or its use will be affected. Therefore, we must pay attention to the temperature in the use process. Humidity should also have a quite suitable environment, it is recommended to be between 40 and 60, not more than 65.

2. There should be a clean production workshop and air source for human environment.

When using FRP grid, it should be careful not to smash heavy objects, burn directly, and lay flat. It can be used as structural material, as floor, platform, ship deck, trench cover plate, maintenance walkway plate, breeding manure leakage plate, etc. with the characteristics of light weight, high strength, corrosion-resistant and flame-retardant, and non-magnetic insulation.
