The winding forming technology of the spiral wound pipe machine is mainly composed of three parts, and these three parts are essential for forming the spiral wound pipe machine. Only by ensuring that these three components are the whole as a whole can the maximum effect of spiral wound pipe machine winding forming technology be exerted.

Raw materials

The raw materials of the spiral wound pipe machine are mainly fiber-reinforced, resins, and fillers.

(1) Reinforcement material spiral wound pipe machine The reinforcement material used for winding forming is mainly various fiber yarns: such as alkali-free glass fiber yarn, medium-alkali glass fiber yarn, carbon fiber yarn, and so on.

(2) Resin matrix The resin matrix refers to the glue system composed of resin and curing agents. The heat resistance, chemical resistance, and natural aging resistance of spiral wound pipe machines mainly depend on the performance of the resin, and it also has a great influence on the manufacturability and mechanical properties of spiral wound pipe machines. The commonly used resin for spiral wound pipe machine winding molding is mainly unsaturated polyester resin. Tianhe resin is an expert on unsaturated polyester resin.Epoxy resin and bismaleimide resin, which are sometimes wound with spiral wound pipe machines, are used in the water supply and drainage glass fiber reinforced plastic pipe project of Shanghai Pudong Airport. For general civilian products such as pipes, tanks, etc., spiral wound pipe machine winding products, such as unsaturated polyester resin, are often used. For spiral wound pipe machine winding products that require high mechanical properties, compressive strength, and interlayer shear strength, epoxy resin can be selected for spiral wound pipe machine winding products. Aerospace products mostly use spiral wound pipe machine winding products with high fracture toughness and good moisture resistance, such as bismaleimide resin.

(3) Fillers:There are many types of fillers for spiral wound pipe machines, which can improve certain functions of the spiral wound pipe machine resin matrix, such as improving wear resistance, increasing flame retardancy, and reducing shrinkage. Adding hollow glass beads into the glue can increase the rigidity of spiral wound pipe machine winding products, reduce density and reduce costs. When the spiral wound pipe machine is used to produce large-caliber buried pipes, 30% quartz sand is often added to improve the rigidity of the spiral wound pipe machine and reduce the cost.

The inner mold of the spiral wound pipe machine to form hollow products is called the core mold. Generally, after the spiral wound pipe machine is cured, the core mold must be released from the product.

The basic requirements for the design of spiral wound pipe machine core molds for winding products ① It must have sufficient strength and rigidity to withstand various loads applied to the core mold during the forming process of spiral wound pipe machine winding products, such as self-weight, product weight, and winding tension ②It can meet the shape and dimensional accuracy requirements of spiral wound pipe machine winding products. ③Ensure that spiral wound pipe machine winding products can be removed from the product smoothly after solidification; ④The manufacturing is simple, the cost is cheap, and the materials are easy to obtain.
