Three-layer co-extruded PP/PE pipe production machine line

Three-layer co-extruded PP/PE pipe production machine line

The 3SPP ultra-quiet PIPE production line recently launched by our company; it can be co-extruded by single/twin screw extruder, and the inner layer of polypropylene is suitable for High resistance to hot water, corrosive liquids and mechanical abrasions. Due to the smooth inner surface, it has good anti-fouling ability and can reduce drainage noise sound. The middle layer is made of modified viscoelastic material PP-m, which strengthens the strength of the pipe, plays a key role in the excellent sound absorption performance of the pipe, and also gives the pipe excellent quality. good rigidity. The outer layer is made of high-impact polypropylene material with good weather resistance, this outer protective layer is extremely strong, smooth surface, representative blue grey. Kangrun has independently developed the "short glass fiber reinforced PP-R steady-state pipe and three-layer co-extruded PP ultra-quiet and foamed pipe high-speed extrusion production line". the student The production line adopts the three-layer co-extrusion technology and adopts the company's uniquely designed spiral co-extrusion die, so that the reinforcing materials are arranged according to certain rules to form a reinforcing layer, which is combined with The inner and outer PP-R (or PP-B) layers are organically integrated into a whole to achieve the purpose of enhancement. So as to overcome the overhang phenomenon when the pure plastic pipe is exposed, and reduce the pipe size. The linear expansion coefficient of the material. Compared with pure PP-R and pipes of the same specification and pressure level, it can save materials and reduce costs. Due to the use of foaming technology in the middle, it can be Replacing traditional cast iron pipes and PVC silencer pipes, specifications 050-0250MM.
