SMC mold has excellent corrosion resistance, light weight and easy and flexible engineering design. Its mechanical performance can be comparable to that of some metal materials. The products made by SMC mould have good rigidity, deformation resistance and wide range of use temperature. SMC mold is a kind of material with excellent electrical performance, corrosion resistance, light weight, easy and flexible engineering design. Its performance is very close to that of metal, so it is widely used in electric meter box mold, automobile mold, etc. SMC composite molded FRP Bridge is a new type of trough cable bridge. Compared with iron trough type cable tray, SMC composite molded FRP tray has the advantages of long service life (generally designed service life is 30 years), convenient installation and low cost (the proportion is only 1 / 4 of carbon steel, and no hot work is required during construction), high strength, good insulation and chemical corrosion resistance. SMC composite molding FRP Bridge is manufactured by SMC composite molding process. The main raw materials are GF (special yarn), up (unsaturated resin), low shrinkage additive, MD (filler) and various additives. SMC composite molding process is a kind of high production efficiency in FRP composite molding process.
SMC composite molding process has many advantages:
1. Short forming cycle, suitable for mass production.
2. Closed mold molding, no styrene and glass fiber scattering, good working environment.
3. The forming process is simple, easy to mechanization and automation, and can be formed even without skilled workers.
4. Large scale products can be formed. SMC molded products have the characteristics of accurate size, smooth surface, good appearance and size repeatability, and complex structure can also be formed once and processed twice without damaging the products. Disadvantages of SMC composite molding process: Press, metal mold, heating device, etc. are used, and the initial equipment investment is large.
SMC composite molded FRP Bridge features: full insulation, safe use: SMC composite molded FRP Bridge is made of SMC composite materials as the name implies. SMC trough type cable bridge has high-performance insulation resistance and breakdown voltage, which can prevent leakage accidents. It can maintain good dielectric performance at high frequency, do not reflect and block the transmission of microwaves, do not rust, and can be used for a long time to avoid electric shock. Corrosion resistance and long service life. SMC composite molded FRP Bridge has good corrosion resistance and can effectively resist the corrosion of water, gasoline, alcohol, electrolytic salt, acetic acid, hydrochloric acid, sodium potassium compound urine, asphalt, various acid-base soil and acid rain. The SMC composite molded FRP Bridge product itself has good anti-aging performance. The surface of the product has a protective layer with strong UV resistance. The double protection makes the product have higher anti-aging performance and is suitable for all kinds of bad weather and maintenance free. Easy installation and handling: the product is light in weight and easy to install. Beautiful and anti-theft: because SMC composite is a thermosetting composite material with low recovery value, it can effectively prevent the theft of cable tray.
