Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in detail below in conjunction with the present invention.

[0016] A PE production process includes cleaning equipment, equipment inspection, starting the extruder, opening the cooling water of the cooling water tank, vacuum sizing, cooling and shaping, and pipe cutting.

[0017] During the test, when each section is heated, it should be heated in stages, that is, the temperature of each section should be heated to 120°C first, and then heated to 160°C, kept at constant temperature for 15 minutes, and finally heated to the process temperature.

[0018] After the temperature of each section reaches the process temperature, keep the temperature constant for at least 30 minutes, and continue to extrude for 15 minutes after the die starts to discharge, exhaust the gas in the original empty screw, stop extrusion, and prepare to start up. When using the PP-R production line to start up, it is necessary to c...

Abstract

The invention discloses a PE production process. The process comprises the steps of cleaning equipment, checking equipment, starting an extruding machine, opening a cooling water tank to discharge cooling water, carrying out vaccum sizing, carrying out cooling and shaping and carrying out pipe cutting. The process solves the problems that a traditional PE production process is large in energy consumption and low in finished product quality.

Description

technical field [0001] The invention relates to a pipe production process, in particular to a PE pipe production process, and belongs to the field of PE production. Background technique [0002] With the acceleration of my country's urbanization process, facing the huge pressure of population, resources and environment, in order to ensure the sustainable development of the national economy, the Chinese government has increased investment in urban infrastructure year by year, and the construction of municipal public pipelines has been accelerating. The specifications are constantly enriched, the output is constantly increasing, and the quality is constantly improving, especially the development of plastic pipes is faster, which has become a hot spot for investment today. At present, in the field of pipe applications, plastic pipes are developing steadily, and have gradually replaced traditional cast iron pipes and cement pipes in water supply, steam supply, and sewage applicat...
