FRP is a derivative of resin. FRP grid is made of resin as the main material and fiberglass as the reinforcement material. Therefore, FRP grid is also called resin grid or resin grid plate.

Generally, unsaturated polyester resin is used to process resin grid. According to the requirements of grid performance, p-phenyl191 resin is used. It can meet most of the requirements in performance. The grid produced has high strength, strong wetting performance, good bending strength and impact strength.
Generally, the viscosity of grid resin is relatively high. In winter, it will be between 350-450. In summer, due to the hot weather, the resin will become thin. Generally, the viscosity will be adjusted to about 500. The strength and toughness of grid plate made of high resin viscosity will be better.
Introduction to common specifications and models of resin grille:
1. The common car washing room and drainage ditch are usually made of 38 * 38 * 38 glass fiber reinforced plastic grid plate of common resin material.
2. It is used in high temperature, high pressure and other occasions, such as some high temperature occasions, it is necessary to use the grid plate made of high temperature resistant resin material.
3. For animal husbandry, 25 * 25 * 25 grid with smaller mesh can be used, and sometimes cross groove GRP grid plate can be used.
The chemical properties of the resin grid mainly depend on the primary function of the matrix resin, while the glass fiber is the "responsibility" of the bearing capacity of the resin grid, so the mechanical functions of the resin grid, such as strength, hardness, flexibility and so on, depend on the glass fiber. Although the two raw materials have different characteristics, they should bear their own responsibilities, but they also have influence on each other rather than absolute Yes, for example, the shear strength and zigzag strength between glass fiber reinforced plastic layers are related to the resin with mechanical function, and the interface state between glass and resin is an important factor influencing each other.
