Second, polyethylene pressure pipe raw material moisture content of the product performance of the impact of high moisture content in the raw material, the surface of the pipe will appear bubbles, dents, severe impact on the pipe's compressive strength. Therefore, the moisture content of PE raw materials needs to be re-tested before extrusion production, especially for mixed ingredients. Due to the carbon black content, carbon black is prone to absorb water, and the moisture content in raw materials is far from the standard, so the raw materials must be prepared before production. Drying treatment. The industry is currently using SFY-100 plastic moisture analyzer to quickly detect the moisture content of various plastic materials. At present, there are two types of drying methods: hot air drying and dehumidifying drying. The former has not a very good drying effect. It is recommended that the manufacturer use the dehumidifying drying equipment to dry the raw materials. Desiccant drying equipment is to treat moisture in raw materials by hot air and molecular sieve adsorption at the same time, the drying temperature is generally not higher than 80°C, and the moisture content in the raw materials after drying can fully meet the national standard requirements. After the raw material passes through the drying process, the content of moisture is reduced and put into the extruder at the same time, the raw material temperature is uniform, and the stability of extrusion production is improved.

Guanya Plastic Quick Moisture Analyzer_Test Method for Moisture Content of Polyethylene Pressure Pipe Raw Material
First, the introduction of polyethylene pressure pipe material PE pressure pipe is mainly used in urban water supply, gas transportation and other aspects, the service life of at least 50a, and to ensure absolute safety. The choice of raw materials is extremely important and sometimes decisive for the ultimate performance of the pipe. The national standard requires that the content of carbon black in the pipe should reach 2.5% and that of carbon black should reach 3. For the moisture content of raw materials for pipes, the national standard also has a clear rule: the content of moisture in raw materials is less than 300mg/kg.
