Reasons why the surface of FRP grating is uneven

When buying FRP grating, users can have an idea of the overall quality of the grating by observing the color, yarn layer distribution, surface smoothness, etc. The dark color is due to the preparation of raw materials, and the uneven distribution of yarn is a problem in operating technology. The reason for the uneven surface of the grating plate is not only due to certain errors in the operating process, but there are three main reasons:
The first operation is in the process. As long as the fiberglass filaments can be evenly distributed, there is a problem with the configuration of the raw resin. If the amount of diluent is too small, the resin will be highly viscous and will easily solidify. Therefore, it is very important to prepare raw materials. Various additives and auxiliaries must be reasonably blended together in strict accordance with standard proportions.
The second is operational skills. Some illegals speed up production and improve efficiency by reducing the number of layers of fiberglass yarn. When fiberglass yarn is used as the matrix, if the amount is small, the overall performance of the fiberglass grating will be unstable, resulting in uneven distribution of surface resin. Wire drawing is a delicate job, very important, and has certain procedures.
The final step in forming the FRP grating is to heat it to solidify it. If the temperature does not meet the standard when heated, the solidification rate of the FRP grating will slow down and the overall stability will be affected. It cannot be completely solidified inside, and the surface will naturally be uneven.
The above three points are the main reasons for the uneven surface of FRP grating. Only by understanding the causes can we prescribe the right medicine to quickly solve the problem and improve the product quality of FRP grating. The three common reasons are all details. Only if each step is performed properly can the quality of the fiberglass grating be up to standard and the appearance smooth.
