From guardrails to harmful weapons: Who is to blame for the ten-year tragedy of fiberglass materials?
Recently, many Shanghai netizens on major social platforms complained about encountering "rail assassins" on the road. Their hands were accidentally stabbed. They could not be completely cleaned up in the hospital and could only wait for it to fall off naturally. After investigation, it was found that the glass fiber was exposed on the road railings. Small fiberglass could also be seen on the protective crossbars and columns at the bottom of the railings.
After in-depth investigation, it was learned that these railings were built more than 10 years ago. At that time, the fiberglass material used to make the railings was widely promoted and used due to its light weight, high strength, corrosion resistance and high cost performance. However, after more than ten years of wind and sun, the material has been seriously aged.
The problem of aging of fiberglass, especially in these applications that are directly in contact with life, fading and yellowing is fine, and the harm caused by resin powdering and fiber leakage will eventually be paid by the entire industry.
It's not that fiberglass is bad. The fiberglass yacht drifting on the sea is still brand new after 40 years. The design life of fiberglass pipes in Europe is 100 years! The biggest problem is that many factories have made good fiberglass bad, which is undoubtedly digging their own graves to endanger the long-term development of the entire industry!
It is not that the factory cannot make FRP well, nor that there is no good FRP, but that the factory owner has a bad heart. It is not that there is no way to supervise, but that the departments with supervision qualifications do not understand the products, and those who understand the products are not qualified. Non-professionals managing the industry is a disaster for the industry and a pain for the country!
In addition to the guardrails mentioned above, what about other applications? What about the skylights? What about those FRP fishing boats, amusement facilities, leisure seats, and landscapes? Should we choose better materials? Should the regulatory authorities do something?
