What factors select the glossiness of FRP grids?

The principle of FRP grille about aggregate: high surface activity, such as silica, impregnated with a layer of silane solvents, can improve bonding strength, aluminum powder and asbestos powder are still active, epoxy and inorganic silicon adhesives have ineffective consequences, asbestos powder makes the heat resistance of the adhesives more outstanding; resin: can be divided into phenolic type, vinyl type, o-phenyl type, m-phenyl type and other four commonly used resins. Saturated resin.
What factors select the glossiness of FRP grids?
It has many kinds and characteristics. Including its corrosiveness, color, acid and alkali resistance, flame retardant and so on are different. Therefore, it is advocated that when we choose FRP grilles in the future, we should select and purchase them according to these two objectives. It is better to be neutral or weak alkaline.
All aggregates do not contain crystalline water and the data are dull; the essential factor is the quality problem of FRP grids themselves. FRP grids are made by interlacing weaving of glass fibers and moulding of resin. The FRP grids with many square and rectangular blanks scattered by rules have the mechanical characteristics of bidirectional homogeneity.
The fiberglass used in FRP grids with better quality is alkali or alkali-free yarn. With high-quality resin and proper proportion of calcium powder, this kind of FRP grids has strong bearing capacity, no obvious cracks and no air holes. It is clear that the service life of this FRP grille will be long.
The characteristics of FRP grille; corrosion resistance of various chemical media, never rusting, long operation period, free from maintenance; flame retardant, insulation, non-magnetic, fine elasticity, can reduce fatigue and improve work efficiency; light weight, high strength, and easy to cut, device, planning, flexible and diverse standards, standard stability.
Sunscreen is the mission of every girl. Assuming that sunscreen is not good, muscles will age. The same FRP grille needs sunscreen in winter. Assuming there is no sunscreen, it will also age. Excellent glass brick fibers such as alkali-free glass fibers have higher strength than steel wires. They have better chemical stability and weather resistance. They hardly absorb water and hardly extinguish when exposed to fire. Their strength is high enough to be used as tire cord.
The use of plastic materials such as PVC boards has been gradually reduced accordingly. We believe that their primary source material has changed fundamentally. Powdery aggregate particle size is small, the choice of raw materials to choose the clasp corrosion resistance and sun resistance, because there is no need to sun protection in winter, sun exposure is fruitless.
The filler of FRP grille is calcium powder or aluminium powder. The high quality filler is fine and white. It is flame retardant. It blends with resin thoroughly. The consumed clamp stick has beautiful color and good transparency and endurance. Environmental corrosiveness is chosen. It is recommended that we still use alkali-free fiberglass. With the development of economy and the progress of science and technology, some new products are coming back and the old ones are withdrawing.
As a new composite material, FRP grille has gradually come back, but the corresponding substitutes such as PP plate, PPR plate and glass fiber can be divided into three kinds of glass fibers: high alkali, medium alkali and no alkali. Generally speaking, the product application ring can be made according to the product. Usually, the poor filler is rough and dim, without flame retardant, the filling material has no gloss, is brittle and has no endurance. The glass brick fiber used by some manufacturers is alkali filament acting as alkali-free filament, the strength of high alkali filament is low, and the water and acid resistance is poor.
