Curing process
The curing of fiberglass can increase the strength by more than 10%, and vacuum curing is one of the effective ways to improve the strength of fiberglass products. During the manufacturing process of the product, there are still some residual solvents and other low molecular weight substances that cannot be completely removed under normal pressure.
Obstructing the strong bonding between resin and fiberglass, thereby affecting the strength of fiberglass products. The use of vacuum curing method can completely volatilize low molecular weight substances, making fiberglass products more dense. Therefore, it can improve the strength of the container.
The curing agent in the adhesive should not be easily volatilized under reduced pressure, otherwise it will cause excessive volatilization loss of the curing agent, resulting in incomplete solidification of the product and reducing its strength.
Process inspection
This process inspection is aimed at the production process. The process inspection implements a self mutual inspection system. The product undergoes self inspection in various processes such as batching, lining, winding, trimming, and demolding, and the next process inspects the previous process. The main inspection content is appearance, size, and inspection structure. Fill in the inspection of the product process and record it, with one record for each product, The product number and process inspection record number correspond to each other.
Finished product acceptance
The final process is finished product acceptance, and the main inspection standards are whether the surface of fiberglass products is flat, smooth, free of impurities, no fibers are exposed, no visible cracks are visible, no obvious scratches, white flowers, and delamination; The outer surface should be flat and smooth, without exposed fibers, obvious bubbles, and severe color imbalance.
