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

Anti-aging

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.

Low cost

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.


Q: The development of steel profiles
China's steel production capacity has reached 5 million tons / year. Most manufacturers can not fully play the capacity, there is a serious overproduction and homogenization of competition. China's steel profiles common national standard is GB / 8814-2004, access to national inspection-free enterprises are also referred to this standard production. Different from Europe and the United States, China's single type of profiles, the market is the bulk of the 60MM Pingkai doors and windows series of profiles and 80MM push-pull series of doors and windows profiles. The above two specifications account for more than 80% of the total consumption.
Q: Steel windows and aluminum windows compare which is more expensive
Wind pressure strength and watertightness: Plastic windows due to the strength and rigidity of the material is low, although through the processing of steel to enhance, but its wind pressure and watertight performance than the aluminum window about two levels. Moreover, due to the steel window steel lining steel is not in its profile cavity angle into a complete frame system, window frame, fan four corners and T-shaped plastic welding angle strength is relatively low, according to the end of 1998 Shanghai enterprises inspection 425 Batch steel window three examples of the situation after the serious analysis of the "plastic window in the high - rise buildings should be used with caution.
Q: Plastic doors and windows and plastic windows do not like?
Plastic doors and windows that use U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features. Plastic doors and windows are made of steel and steel profiles of doors and windows, steel profiles are made of plastic and steel profiles made of mixed.
Q: What is the quality of plastic steel profiles in the end?
Quality in general, market acceptance can be, but the price is relatively high.
Q: Specification for steel profiles
That might be a titanium alloy, and now the kitchen is very popular. A lot of wardrobe are used to do that, I have not done. I have 40 steel small profile, you can use screw connection, can also be welded
Q: Plastic doors and windows and plastic doors and windows have anything to do
PVC plastic doors and windows in the country is widely known as the steel doors and windows, plastic doors and windows is based on polyvinyl chloride (PVC) resin as the main raw material, with a certain percentage of stabilizers, colorants, fillers, impact modifier, Absorbent (shielding agent) and other additives, the extrusion of the material. Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
Q: What belongs to plastic profiles
Plastic profiles are used more: window frames, staircase handrails, troughs, wall feet, shaped tubes and so on. Raw materials are mainly hard PVC, a few are semi-hard PVC, soft PVC, polyurethane low foam and other materials. Plastic profiles with its excellent thermal insulation performance is listed as one of China's key development of building materials. In the production of plastic profiles, the need to pay attention to what problems in order to ensure the quality of profiles and technology.
Q: What is the broken bridge of aluminum? What are the characteristics?
Waterproof, fireproof, anti-theft performance: broken bridge aluminum doors and windows with a rainwater structure designed to completely separate the rain from the outdoor, watertight in line with national standards; its aluminum alloy material for the metal material, Can be a good solution to the family fire hazard; for anti-theft performance is good, because the broken bridge aluminum composite window prepared a good hardware accessories and senior decorative locks, thieves face it can only helpless.
Q: How to identify the installation of plastic or plastic
According to the characteristics of profiles, the profiles are roughly divided into European and American two. European doors and windows of its characteristics are: profile formulations still use the traditional lead salt heat stabilizer, a small number of countries and enterprises began to use environmentally friendly organic tin heat stabilizer; main section of the profile profile is generally designed for three or four main chamber, The total number of chambers to 6 to 8, wall thickness is generally 2.5 ~ 3.0mm. Doors and windows with fan-fan frame structure, fan section larger, with pulley, can be removed; built-in glass, dry mosaic; window open in the foreign under the hanging window-based, a small amount of sliding window.
Q: Bathroom plastic door with what material to do
1 PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect. In addition, UPVC resin powder is also added to the pigment mixture extrusion of the body dyeing technology. But there are still different views on this technology, it should be particularly careful in the selection, to check the kind of profiles by artificial accelerated aging test after the color changes. It is recommended to coat the color film with the color film to improve its weatherability.
