Background
The MPP pipe is a novel pipe and has the characteristics of excellent corrosion resistance, high strength, long service life and the like. The production process of the MPP pipe comprises the following steps: firstly, weighing and mixing various raw materials according to a certain formula according to the component proportion of the MPP pipe, heating the mixed raw materials, then, feeding the raw materials into an extruder, extruding the raw materials into particles, preprocessing the prepared particles, and feeding the particles into the extruder for extrusion and extrusion. During extrusion, the quality of the product needs to be ensured by adjusting the parameters and temperature of the extruder, wherein the extruded pipe needs to be cooled to harden. Generally, water cooling or air cooling is adopted, the pipe is harder after being cooled, quality detection is carried out on pipe diameter, wall thickness and the like, and when the pipe is strictly detected, products meeting the requirements are packaged in boxes and then are stored in a warehouse for waiting for delivery.
In the production process of the MPP pipe, the MPP pipe and the MPP pipe or the MPP pipe and the connecting piece are required to be welded in a hot melting mode, so that a hot melting machine is required to heat raw materials at the end of the MPP pipe, and the raw materials are made of polypropylene. The polypropylene is a thermoplastic polymer, so that raw material polypropylene at the end part of the MPP pipe is heated and melted, the end parts of the MPP pipe can be conveniently and better mutually connected in a melting way, the principle of the hot melting machine is that the surface of the MPP pipe is extruded and overlapped by heating the end part of the MPP pipe to reach the temperature above the melting point, and the specific steps are as follows: and (3) preparing pipes of proper types and sizes in advance, ensuring that the MPP pipe assemblies can be assembled completely, respectively aligning and clamping the ends of the two MPP pipes to be connected with a heating plate, ensuring that the positions of the MPP pipes are unchanged, starting heating operation, waiting for about one to three minutes until the ends of the MPP pipes reach a temperature above a melting point, pushing the MPP pipes in and screwing the plugs immediately after heating is finished, bonding the MPP pipe assemblies together, standing for a period of time, and retesting the MPP pipe assemblies when bonding is finished.
