Process flow of epoxy glass fiber reinforced plastic winding pipe

The good quality of the product is reflected in its exquisite appearance. Through the analysis and research of similar products, it is found that the interlayer property of the epoxy glass fiber reinforced plastic winding pipe is closely related to the transparency of the pipe. The specific transparency of the epoxy glass fiber reinforced plastic winding pipe refers to the wall thickness of the pipe. Transparent in a small range, as far as ordinary epoxy glass fiber reinforced plastic winding pipe is concerned. Why is the tube transparent. The main reason is that there are relatively few bubbles inside the tube, and the epoxy resin glue can more fully infiltrate the glass fibers, eliminating the bubbles and strengthening the resin glue has a great effect on the infiltration degree of the glass fibers and the interlayer performance of the tube. Great help. In this regard, in order to improve the performance of the interlayer, the most important thing is to strengthen the degree of infiltration of the resin glue to the glass fiber and minimize the air bubbles in the tube.

Generally speaking, the pouring body of epoxy resin glue is often in a transparent state, but when it is stirred and heated to cure, bubbles appear, so the obtained bubbles are also opaque materials. There are a lot of air bubbles in the resin glue. The monofilament of glass fiber is also in a transparent state. According to the relevant data, if the absolute refractive index of the two materials is similar, combining the two similar materials will produce relatively high transparency. In the process of FRP forming, the diameter of some bubbles is often much larger than the diameter of glass fiber. Large bubbles can be avoided by forming technology. However, if epoxy resin glue with high viscosity is used to infiltrate glass fiber At times, it is unavoidable to have small air bubbles in FRP. Although the number of small air bubbles can be reduced by using special means, it cannot be completely eliminated. In FRP pipes, the gaps and bubbles around the glass fibers are often connected to each other, and a continuous channel can be formed on the phase interface. In this way, it is very easy for moisture to flow to the depths along the phase interface, thereby causing damage to the glass steel pipe. Therefore, epoxy resin glue should be used to infiltrate the glass fiber, which not only strengthens its anti-penetration ability, but also makes its bonding more tightly.
