FRP grille: with unsaturated polyester resin as the matrix, plus calcium powder and auxiliary materials such as color paste, grille through FRP
staggered system, resin casting overall pressing mold, a special processing compound with a lot of blank plate products. Can be widely used in petroleum, chemical, electric power, paper industry, electroplating, Marine exploration, sewage treatment and other industries of the work platform, drilling platform, equipment platform, operating platform, corridor, etc., is the ideal product in corrosive environment, but also suitable for civil building facilities.
FRP grating raw material
Enhanced glass fiber: high tensile strength, excellent penetration performance and resin basic solid combination, so that the product has excellent mechanical properties and corrosion resistance;
Unsaturated polyurethane resin: colorless and transparent, low viscosity, low heat release, low shrinkage. High speed curing, the production of grid smooth, high strength, good toughness;
High quality calcium powder filling material: calcium powder plays a skeleton role in FRP Grating products, improve the hardness of the grid, and high quality filling material with flame retardant, smoke suppression, high transparency and toughness;Low carbon environment-friendly pigments: adopt low carbon environment-friendly pigments, with good coverage, strong coloring force and strong dispersion.
The four major production processes of FRP grille:
- Common glass grille – no cover plate, common market, good drainage performance;
- FRP frosted grille cover plate — better anti-skid performance;
- FRP microporous grille cover plate — the microporous is more solid and has better load-bearing capacity;
- FRP grille cover plate — prevent liquid leakage and gas volatilization;
- FRP grid commonly used thickness is generally 25mm, 30mm, 38mm, 50mm, 65mm,
- Grille square hole specifications are generally 38mm*38mm, 40mm*40mm, 50mm*50mm, etc.
- Thickness is not the same as the use of the environment is different.
- FRP grid plate size is generally: 1.22* 2.44m, 1.22* 3.66m, 1* 4.04m, 1*2M;
- The color of FRP grille is generally red, yellow, green, blue, gray, black and so on.
Although take measures such as anti-corrosion layer; However, the corrosion of the components is serious, which not only leads to the bad production environment in the factory
Poor, and affected the safety of production, enterprises had to stop maintenance. But in these areas if the use of FRP grille as a material can be very good anticorrosion effect, FRP grille has a long service life, low cost, safe and reliable, and no maintenance. Beautiful and generous from the design, a variety of colors can be chosen, is the first choice of many enterprises today. In developed countries, FRP composite products have been widely used for many years, and the production, use and sales of FRP grille have initially reached normalization, serialization, commercialization, and the amount is also very large.
FRP grating performance characteristics:
- Corrosion resistance: it has excellent corrosion resistance of acid, alkali, organic solvent and salt and many other gas and liquid media, and has incomparable advantages in the field of corrosion resistance. According to the requirements of the actual use occasions, the use of o-benzene type, m-benzene type, vinyl type resin can be economically selected as the matrix material.
- Light weight and high strength: the density of fiberglass grating is not more than 2, only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid PVC, and its absolute strength exceeds the level of aluminum and ordinary steel.
- Aging resistance: service life of more than 50 years.
- Flame retardant: the flame propagation rate of common flame retardant grille (ASTM E-84) shall not exceed 25; The flame propagation rate of advanced flame retardant vinyl grille does not exceed 10. Oxygen index not less than 28 (GB 8924)
- Safety: Excellent electrical insulation, no breakdown under 10KV voltage; Non-electromagnetic, can be used in magnetic sensitive equipment; The special structure of FRP grating also has the characteristics of anti-slip, anti-fatigue and so on
Application scenarios of FRP grille:
- Streets on both sides of the trees around the trees (for short, tree grate);
- Water treatment in the maintenance aisle, sewer cover, large containers, etc.
- Platforms, ship decks, walkways and stair treads in the transportation industry;
- Trench cover plate, operation workshop, high cleanliness workshop in the electronics industry;
- Trench cover of chemical water workshop in power plant, waste water pool, etc.;
- Stair pedals, operating platforms and double-deck platforms in chemical plants;
- Offshore oil operating platforms for the petroleum industry;
- Car wash/car beauty shop in the car wash room drainage floor, parking space, car beauty maintenance trench cover plate, etc.
- The animal excrement barrier floor in the special enclosure for animal breeding in the breeding industry;
