The glass fiber reinforced plastic plate is made by a fully automated production line using raw materials such as gel coat, resin, glass fiber, and film. Compared with hand-laid glass steel plate, FRP machine-made board has uniform thickness and stable quality. Because it is produced mechanically, the production efficiency is much higher than that of hand-laid glass steel sheets. But whether it is a machine-made board or a hand-made board, it is inevitable that it will be subjectively or objectively affected in the production process to cause such and other problems. The problem is not terrible, but we must know how to find the cause and solve the problem.
The gel coat gloss of FRP products is not good, the reasons are:
1. The mold has poor finish and dust on the surface.
2. The content of curing agent is small, the curing is incomplete, the curing degree is low, and the curing is not post-cured.
3. The ambient temperature is low and the ambient humidity is high.
4. The gel coat layer is not completely cured before demoulding.
5. The inner layer of the gel coat has high filling material and less matrix resin content.
Summary: In the production of glass fiber reinforced plastic machine-made plates, workers should pay attention to the temperature and humidity changes in the production environment, as well as the management of the mold, and the curing of the gel coat layer during production.
