Introduction of the working principle and development of FRP winding process

The reason why there are dozens of glass RP products, this is the inevitable result of development. The products produced by a single production process will have some defects in the performance. For example, although the glass steel purification tower made by hand paste process can be used, the manual production cost is too high, and it is gradually replaced by the winding process of semi-automatic production. This paper will introduce the working principle and development of FRP winding process.
What is the principle of FRP winding process: generally speaking, FRP winding forming process is to cover the raw materials needed to make the product evenly on the winding mold, and then solidify the product through heating.(FRP guardrail) and the analysis of the winding molding process principle, mainly is to study the winding law, that is, the relative movement between the guide wire head and the core mold, to meet the fiber uniform, stable and regular fiber winding to the core mold. Through the study of the winding law, we can find out the quantitative relationship between the structural size of the product and the linear type and the relative movement of the guide head and the core die, so as to determine the best winding process system of the specific product.(Tree grate)
The present situation and development of FRP winding process: at present, winding products are used in both military and civilian aspects. Military products are characterized by high performance and accurate winding structures. The main civil products include storage tanks, pipes and pressure vessels, especially the application of field winding technology, which solves the problem of limiting the size of large storage tanks in the past, greatly expands the use range of winding products, while the production of sand fiber winding pipeline opens up the application of FRP pipes in the water supply system.(FRP centrifugal fan)
Although in the production of tank products, winding process and hand paste process has great advantages, and can improve the quality of products, but there are still many problems to solve: a, the structure design of winding process and structure design is still not close enough, should be further strengthened, through the structure structure form and design parameters to finally determine the reasonable process system, to improve product quality, production efficiency and technical and economic indicators.(FRP spray tower) b, the performance of production raw materials in the winding process are synthetic resin and glass fiber, followed by some curing agents, promoting agents, thinner, flame retardant and other auxiliary materials. At present, there are not many studies on the performance and characteristics of resin and glass fiber materials, such as temperature resistance, corrosion resistance, and extension rate of materials, which need further research.(FRP scrubber) c, development of winding equipment In fact, the structure of the winding equipment used in the winding process is very simple, but there are many shortcomings, and further research is needed to ensure the maximum stability of the production process, the reliability and durability of the products, and improve labor productivity. D, because the changes of raw materials and process have a great impact on the product performance. Therefore, it is necessary to inspect and manage the various links of the whole process from raw materials to products, and establish a sound and strict quality inspection and management system.(FRP centrifugal fan type selection)
