Glass fiber reinforced plastic grating(fiberglass) is a kind of inorganic non-metallic material with particularly good performance and high strength.The anti-corrosion FRP grating has excellent corrosion performance of acid, alkali, salt and many other gas and liquid media. It has incomparable superiority in the field of anti-corrosion. According to the requirements of actual use occasions, o-phthalic, isophthalic, and vinyl resins can be economically selected as the matrix material.
FRP grating is made of glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is a few microns to more than 20 meters, which is equivalent to one 1/20-1/5 of a hair strand, each fiber strand is composed of hundreds or even thousands of monofilaments. Glass fiber is generally used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy.
FRP grating generally has a measurement range between -20 degrees and 80 degrees. If it is higher than a certain range, it will deform or cause it to be reacted. Therefore, the FRP grating can be used in general use occasions. There must be a definite specification for a good quality FRP grating: FRP grating is a kind of board with many spaces made by special processing and compounding with glass fiber as the reinforcing material, without full polyester resin as the matrix. Shaped grille, strong resistance to low temperature, bright color, strong designability, and service life of up to 50 years, so it is widely liked by everyone and widely used in various fields.
The use of FRP grid plate:
1. Fuel chemical industry: Because of its good corrosion resistance, FRP has satisfactory applications in fuel, water conservancy engineering, textile printing and dyeing, and food processing.
2. Electricity: Because of its excellent performance, the extruded glass fiber reinforced plastic trench cover is widely used as an insulating support member, a high-voltage cable tray, a receiving antenna column, and a high-voltage current operating rod.
3. Transportation: FRP trench covers are used as pressing branches and corner boards in trains and vehicles. Of course, they can also be used as high-speed road guardrails, sound-absorbing panels, and anti-glare panels.
4. Construction: It can be used as roof support to construct guardrails, doors and window frames.
In the glass fiber reinforced plastic grid, the toughness of the grid can be enhanced is the fiberglass fiber wire. Good glass fiber reinforced plastic fiber yarn, such as alkali-free glass fiber reinforced plastic fiber, has a certain toughness, chemical stability, good weather resistance, almost no water absorption and fire, and its high strength can also be used as tire cord. The FRP fiber yarn used by some manufacturers is high-alkali yarn as an alkali-free yarn, which has low strength and poor water and alkali resistance. The filler of the FRP grid is calcium powder or aluminum powder. The high-quality filler is fine and white in nature, flame-retardant, and completely compatible with the resin. The board produced is beautiful in color, good in transparency, and strong in toughness. On the contrary, inferior fillers are rough and dull, and are not flame-retardant. The produced boards have no gloss, and are relatively brittle and tough.
