Insulation resistance of FRP grille
FRP grating products are insulated and impact resistant, not easy to deform and reduce fatigue. FRP gratings have high impact strength and allow repeated bending without permanent deformation. After impact, metal gratings retain permanent deformation and need to be repaired. . The FRP grille has moderate elasticity, which makes people who work on it for a long time feel comfortable, reduces the sense of urgency of the staff's legs and back, reduces the occurrence of accidents, and helps improve production efficiency. Corrosion resistance, long service life, never rust, and maintenance free. The grid has very good resistance to acid, alkali, organic solvents and salts, and many other gas and liquid media. It has unparalleled advantages in the field of anticorrosion. It is different from the traditional metal grille. It does not cause electrochemical corrosion and rust under the action of chemical media, and therefore does not cause the structure of the material to be damaged. It does not require regular or irregular inspection and maintenance. Different from wood and other materials, they will rot, mildew and other phenomena. It is an upgrade product of traditional iron, wood, cement and other materials. According to the requirements of actual use occasions, we can economically choose to use o-benzene, m-benzene, and vinyl resins as the base material. The service life is more than 50 years, which greatly improves the service life. Flame retardant and insulated, FRP grille cover has excellent electrical insulation, no breakdown at 10KV voltage; no electromagnetic properties, can be used on magnetic sensitive equipment; special structure of FRP grille also has non-slip, anti-fatigue, etc. characteristic. Generally, the oxygen index (tested according to GB 8924) of the glass-glass steel grid is above 32, and the flame propagation rate (tested according to ASTM E-84) is flame retardant level one; the flame propagation rate of the high flame retardant vinyl grid reaches below 10 And has been approved by the American Bureau of Shipping (ABS). Non-magnetic, FRP grille cover is non-electromagnetic and can be used on magnetically sensitive equipment. There is no electric spark, and the grid has no electric spark. The use of the grid avoids the danger of explosion and fire caused by sparks that may be generated by tools falling on the metal grid in flammable and explosive places.
