How to choose FRP grating?
1. It is necessary to determine what the FRP grating is used for, that is, to clarify its use goal. For example, the manufacturer of the car wash is to buy the grille board to prepare to use the grille board as the carrier board for the car wash.
2. After determining the purpose of the FRP grating, it is time to determine the size and specifications of the grating used. Through the relevant introduction of the manufacturer, you can have a general understanding of the grille. For example, in a car wash, you can choose a 2.5cm thick grille or a 3.8cm thick grille. In electroplating equipment factories, grid plates with a thickness of 2.5 cm are commonly used. In sewage treatment plants and chemical plants, 3.8 cm thick grid plates are often used.
3. After selecting a suitable thickness of the FRP grating, the size of the grating plate during use should be calculated. Such as in a car wash. The size of a car wash is mostly 1.220m*2.440m, while the size of the FRP grille is 1.220*3.660, which needs to be cut before it can be put into use.
4. Choose appropriate raw materials to make FRP gratings that meet the requirements. For gratings used in chemical plants or sewage treatment plants, it is necessary to select resins with higher corrosion resistance for production.
Different top finish can be customized according to your request, the most popular is smooth, concave, gritted.
Quality recognition
A. Selection of raw materials
The raw materials used in the FRP grille are resin, fiberglass fiber wire, and calcium powder as the filler in a ratio of 1:1:1. The high-quality FRP grille is made of high-quality resin: unsaturated phthalic resin 196, colorless and transparent . Low viscosity, low exotherm, low shrinkage, high-speed curing, high-speed compatibility, bright gloss. The produced FRP grating is flat and smooth, with good gloss, high strength and certain toughness. If you use inferior resin, it will be completely opposite. Inferior resin is turbid, high viscosity, high exotherm, high shrinkage, relatively slow curing, and poor compatibility. The fiberglass grille produced has many pores, is easy to break, and has poor strength. Toughness is not good.
In the glass fiber reinforced plastic grid, the toughness of the grid can be enhanced is the fiberglass fiber wire. High-quality fiberglass fiber such as alkali-free fiberglass 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 filler of the FRP grid is calcium powder or Al(OH)3 powder. The high-quality filler is fine and white, has flame retardancy, and is completely integrated with the resin. The produced board has a beautiful color, good transparency and good 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.
B. Comparison of finished products
The appearance of high-quality FRP grating products has no obvious cracks, fewer pores, bright and pure color, good transparency, a certain degree of toughness, high surface finish, and long service life; while inferior FRP grating products have cracks in appearance, There are more pores, and the color is not pure and the gloss is not enough. Its service life is also short.
