Silicon-cored pipe production technology

Abstract

The invention provides a silicon-cored pipe production technology. The technology comprises the following steps: 1, selecting and proportioning 100 parts by weight of a special material for silicon-cored pipes, 40-60 parts by weight of high density polyethylene, 15-20 parts by weight of a metallocene modified master batch, 3.5 parts by weight of a black master batch and 4 parts of an antioxidant master batch; 2, synchronously extruding and compounding above materials through three extruders; 3, carrying out vacuum cooling shaping: cooling and shaping extruded and compounded pipes through a vacuum refrigerator and an immersion cooling water box; 4, carrying out meter counting printing to make the length of every silicon-cored pipe coil be 2000-3000m; and 5, pulling and reeling the silicon-cored pipe coil to obtain the finished silicon-cored pipes to be sold and used. The silicon-cored pipes produced through the technology have high tensile strength and good elongation at break, and can well meet market use demands.

Description

technical field [0001] The invention relates to the technical field of silicon core tubes, in particular to a silicon core tube production process. Background technique [0002] Silicon core tube is a new type of composite tube with silica gel solid lubricant on the inner wall. It has good sealing performance, chemical corrosion resistance and low engineering cost. It is widely used in optical cable communication network systems such as highways and railways. At present, the silicon core tubes commonly used in the market are processed by blending special materials for silicon core tubes, polyethylene raw materials, color masterbatches, and anti-oxidation masterbatches. The tensile strength and elongation at break are relatively poor. Fractures often occur, and the tube is prone to breakage in the entire roll after it is placed on the construction site for a period of time, which cannot meet the use requirements. Contents of the invention [0003] In order to overcome the ...
