What are the factors that affect the quality of glass fiber reinforced plastic grid
Synthetic resin. Synthetic resin is used as the substrate of glass fiber reinforced plastics, which is used to paste the glass fiber into a whole. Because the resin is the base material, it has influence on the elastic modulus, heat resistance, electrical insulation, permeability, chemical corrosion resistance, weather resistance, aging resistance and so on.In addition, the interface is also an important factor affecting quality. The high performance of glass fiber reinforced plastic (FRP) grid cover is related to the quality and durability of the interface between fiber and resin. The interface has a great influence on the performance of glass fiber reinforced plastic grid. As everyone knows, the glass fiber is a cylindrical glass surface, such as glass, smooth, and the surface is often firmly adsorbed with a thin layer of water film, which certainly affect the bonding properties of glass fiber and resin. Especially in textile glass fiber drawing process, in order to achieve the collection, lubrication, eliminate the static, often coated with a layer of wetting agent, the wetting agent is the most paraffin substances remained on the surface of glass fiber on them, the isolation effect on synthetic resin and glass fiber, with both adhesive.
The first is glass fiber. Glass steel fiber can improve the tensile strength and the elastic modulus of FRP pultruded grating plate, but also can reduce shrinkage, improve the heat deformation temperature and low temperature impact strength, therefore is glass steel grille pultrusion cover the main load-bearing part.
FRP grating is a kind of material in recent years is more popular, this is a kind of grid plate after special processing, except for the corrosive environment, it is widely used in city greening, landscape decoration and so on, is the most common in the city green, so as a kind of glass steel products, what are the factors affecting the quality of FRP grid cover?
