Fiberglass signs is a traffic safety products, a road traffic signs, materials fiberglass, fiberglass material because no recovery value, also known as anti-theft signs. Road traffic signs warning the ban is passed instructions with text and images to drivers and pedestrians to manage road traffic safety facilities. It gives the exact road users to road traffic information to enable the smooth flow of road safety, a matter of life and property safety of drivers and pedestrians, is an indispensable traffic safety ancillary facilities.
Reflective film adhesion properties
Hand lay fiberglass materials, processes for handmade, natural cooling products, resin with hardener reaction occurs under natural conditions, often accompanied by gas production, so easy blistering after affixed reflective film, and, manual operation, because people it is often uneven wall thickness and other factors, is not suitable for mass production.
Extruded fiberglass craft. Subject to the requirements of due process, extruded fiberglass surface uneven, with pores, so lack of reflective film adhesion. Therefore, it is inappropriate to make traffic signs backplane.
Molded fiberglass. Molded fiberglass is molded under heat and pressure, surface flat, reflective film adhesion to meet the requirements. According to the Ministry of Transportation test reflective film adhesion properties for signs bottom experiment five minutes later, stripping length of reflective film is 3-4mm, significantly less than the requirements of the standard 20mm.
Strong wind load
After the hand lay-up FRP materials, the hand lay fiberglass signs on the water a month later to do stretching, bending test, the intensity decreased by 50%, since the material is not at a high temperature, high pressure molding, interior materials have bubbles, bubble water to carry out hydrolysis, the material greatly affect the strength, not for mass production.
PVC with strength aluminum panels are too low, probably in 10-20Mpa, on the coast, the wind will be able to board at the connection point to blow off.
Extruded fiberglass craft, longitudinal tensile strength is not enough.
Molded fiberglass. Molded fiberglass is molded under heat and pressure, mechanical strength, transverse and longitudinal direction force is uniform. Strength 80Mpa more
FRP materials aging in the atmosphere mainly solar radiation, high temperature, humid air and the mechanical action of wind and rain, resulting in fiberglass resin surface off, exposing the white silk, weight loss, while the ultraviolet light degradation of the active substance, oxidation, fiberglass color yellowing. For the above phenomenon, must join the anti-aging agents, anti-UV agents, delay the aging process. Signage is used outdoors, when it rains, the water resistance of different resins big difference, phthalic unsaturated resin is better than vinyl unsaturated resin water resistance. Therefore, it is important for selecting the appropriate resin on the plate.
Anti-aging performance parameters and test methods specified in Table 2, the Ministry of Transportation sign resin floor.
To save costs, reduce waste, more conducive to customer acceptance, demand for small flag shape a mold. Minimize waste.
Currently, the market triangular signs 70090011001300, 60080010001200 garden party license plate 1 m * 2 meters, the company has opened a mold can be mass-produced.
There are ribs on the back of the structure, used to enhance the overall strength of the product. And nuts embedded in the production process into products, convenience products with hoop screw connection, the product cost is lower than the aluminum plate of the same thickness, more conducive to market acceptance.
Signs board FRP technology, is an ideal and sophisticated traffic signs.
