On-line continuous extrusion sand layer FRP pipe production line
Product Description
1. In the production of FRP sand-filled pipelines, the sand-filled layer is usually formed by wet method or dry method. The defect is that the resin and quartz sand are not mixed uniformly, and the density of the quartz sand layer is not enough, which affects the tensile strength and stiffness of the pipeline. . When subjected to external loads, impacts, and rolling, the pipeline is prone to deformation, cracks, or even cracking and falling off, which causes difficulties in the safe transportation and maintenance of the pipeline, and directly restricts the promotion and application of sand-filled pipes.
2. On-line continuous sand-extruded FRP pipeline equipment adopts the on-line continuous sand-extrusion process, which reduces the gap between sand grains, completes the high-pressure, high-density molding of the sand-included structural layer, doubles the strength of the pipeline, and reduces the The amount of resin used saves the cost of raw materials. The equipment can be applied to the production process, equipment optimization and product upgrading of continuous winding FRP sand-filled pipes, centrifugal casting FRP sand-filled pipes, and FRP pipe jacking. For the domestic original production process.
3. Technical route:
With the help of continuous winding glass fiber reinforced plastic pipe production equipment, the formation of the sand layer structure on the pipe wall is completed online.
A. Pre-mixing: Quantitatively transport quartz sand, short fibers and resin according to the preset ratio, and uniformly mix them into bulk wet materials through mixing equipment; B. Extrusion: Use extrusion devices to
press the mixed bulk materials into mud-like lumps C.
Forming: extrude the quartz sand structure layer in the inner and outer molds of the pipeline.
4. Key technology:
uniform mixing of materials;
implantation of chopped fibers in the mixture;
continuous extrusion of high-pressure sand-inclusion layer;
precise control of sand-inclusion layer thickness;
solidification node control.
5. On-line continuous extrusion FRP pipe process equipment for sand layer, providing technology, equipment optimization and products for fixed-length reciprocating winding FRP sand pipe, continuous winding FRP sand pipe, centrifugal casting FRP sand pipe, and FRP pipe jacking manufacturers A new option for upgrading.
