Fiberglass grating is usually used as the cover plate of the terrace ditch of the floor pedestrian passage operation platform. The common colors are medium yellow, grass green and medium gray. It can be processed into three surface forms of groove, sanding and plane, or covered with 3-6mm thick diamond pattern or sanding cover plate.
The performance characteristics of FRP grid are closely related to resin and fiberglass. Let's analyze them in detail:
[introduction to resin type]
Phenolic resin: about 80 oxygen index, low toxicity and high flame retardant, used for high temperature fire protection and low smoke area,
Vinyl resin: oxygen index 35 or above, it is used in places with high flame retardant requirements and acid-base resistance.
M-benzene resin: oxygen index 28 or above, used in the environment with strong acid corrosion and general alkaline corrosion.
M-benzene food grade resin: oxygen index 26, mainly used in meat products and food processing
O-benzene resin 1: oxygen index 28 or above, used in general acid and alkali resistant environment
O-benzene resin 2: oxygen index less than 28, used for occasions without flame retardant requirements
[introduction to types of glass fiber]
Alkali free roving: used in occasions with high strength and corrosion resistance requirements
Medium alkali roving: used in the environment with low strength requirements and corrosion resistance requirements
Generally, fiberglass gratings are produced in the way of whole plate. When small plates are needed, they can be cut and processed reasonably according to the size and installation requirements. Ceramic disc or emery disc cutter can be used for cutting on site, or even ordinary hacksaw blade can be used. Generally, portable angle grinder, grinder, ordinary file and sandpaper are used for grinding.
