Product Description:

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:What belongs to plastic profiles
Plastic Profile A: Impact modifier Plastic profiles, such as without impact modifier, plastic profiles will be very brittle, slightly collision, easy to break. Plastic profiles used in the production of anti-impact agent modifier mainly by the following three categories: chlorinated polyethylene, polyacrylates, ethylene - vinyl acetate copolymer. Plastic profile additive two: heat stabilizer Plastic profile is a thermosensitive plastic, so in the production and processing of plastic profiles, heat stabilizer is essential. The metal salt in the heat stabilizer absorbs the HCL from the PVC, so it can delay the decomposition rate of the plastic and prolong the decomposition time. The most commonly used in the production of plastic profiles is the compound lead salt, which has high thermal stability and low cost. Plastic profile additives three: lubricant The main role of the lubricant is to reduce the polymer and processing equipment and polymer molecules between the internal friction between the friction caused by excessive heat caused by resin degradation, improve the efficiency of heat stabilizer.
Q:How plastic embossed profiles are made
Preloading To improve the quality of the product and improve the molding efficiency, the powder or fibrous molding compound is pre-pressed into a certain shape.
Q:Plastic steel window profile material
I do not know upstairs two self-proclaimed expert, in the line and do so long. According to the national market, the top three domestic brands is nothing but Shide, Conch, Finance, three years ago I work in Shide, and now I work in the financial. I do not know the landlord said the profile of the brand, but the beginning of this year Shide new 7 sealed series did in the building materials city speculation to the two hundred and seventy-eight. If the landlord said the profile is not this, then the 280 price is high and understandable. In addition to the grade of the profile is this argument, GB 8814-2004 according to the thickness of the main profile of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" A type of material requirements wall thickness 2.8 / 2.5mm, B type requirements of wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B. In addition, I answered the second floor of the problem, Jinpeng profiles according to the national market is also a good profile, ranked fourth in the current controversy is not large.
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:Plastic steel profiles how to open V mouth
Plastic profiles open V mouth has a special V mouth saw, with a manual cutting machine are not allowed, angle, V port depth can not be determined.
Q:The development of steel profiles
From the European to the American: European-style profiles are the mainstream of the market, but the rapid development of American profiles, which is due to some exports to the United States of steel-steel production enterprises driven by the United States as a lively, beautiful, delicate structure, delicate lines, Decorative, high light rate, high perspective, etc., has won the favor of consumers.As European-style profiles in China has 20 years of history, the US profile short-term can not replace the European profile in China's position. European-style profile is concerned about the fan package box, and the American profile is a box fan. Domestic steel doors and windows are basically fan package box.
Q:What is the material of steel
In the building construction is mainly used for sliding, sliding doors and windows, fence, pipe and ceiling material applications, through the new process is also widely used in automotive engine protection board, not only light weight, and good toughness, with just fine Nature, and sometimes also known as alloy steel.
Q:Plastic doors and windows and plastic windows do not like?
According to the material plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows. The following are the same as the " 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. The following are the same as the " 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. The following are the same as the " 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.
Q:How many meters of a conch plastic steel profile
Plastic specifications of a lot of steel, do not know what you want to know? But each type of material has a standard weight of rice, their own to know, for example: Conch 60 two-track sliding box weight is 1.22kg, then 1000kg divided by 1.22 = 819 meters
Q:Is the powder produced when the crushed plastic is crushed?
Plastic crusher Plastic crusher refers to the crushing of various plastic and rubber such as plastic profiles, pipes, rods, silk, film, scrap rubber products. Granules can be directly for extrusion, as the production of raw materials.
