Step 2, mix material loading, the mixture mix and blend that step 1 is described, and oven dry, and described bake out temperature is less than or equal to 65 ℃, automatic charging after oven dry.
Step 3, extrusion moulding, the mould of extruding is that spiral Mould Machining forms, and the length-to-diameter ratio of this mould is 33: 1, and the temperature of described extrusion moulding is 170 ℃-190 ℃, carries out Vacuum shaping after extrusion moulding, and is cooling, the described spraying cooling that is cooled to.
Step 4, cutting, cooling rear employing sync pulling, planet cutting.Step 5, deflashing after cutting, declare through self check, stacks warehouse-in.
2. a kind of operating mine as claimed in claim 1, with the production method of high-performance polyethylene tubing, is characterized in that the modified additive that adopts in described step 1 is oxidation inhibitor.3. a kind of operating mine as claimed in claim 1, with the production method of high-performance polyethylene tubing, is characterized in that the sync pulling described in described step 4 adopts automatic meter counter towing mechanism.
4. operating mine high-performance polyethylene tubing, it is characterized in that described tubing adopts method as described in claim 1-2 to make, the elongation at break of prepared polyvinyl piping materials 〉=360%, tensile strength 〉=13Mpa, the arithmetical av of surfaces externally and internally resistance≤100000 ohm, the length-to-diameter ratio of tubing are 33: 1.
The planet cutting refers in the cutting of pipe rotation limit, outer wall limit.
Beneficial effect:
The resistance value footpath of this polyvinyl piping materials surfaces externally and internally meets the relevant criterion requirement, and is antistatic and explosion-proof performance is good, and lightweight, long service life, and corrosion-resistant, shock-resistant, fluid resistance is little, and flame retardant properties is outstanding, has stronger propagation and employment and is worth.
