Background

PVC pipe (hard polyvinyl chloride pipe) is made up by using polyvinyl chloride resin, stabilizing agent and lubricating agent through the processes of mixing, hot-pressing and extrusion-forming, and is a plastic pipe material which can be developed and applied at first. The PVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture, but is only suitable for a water supply system with the conveying temperature not exceeding 45 ℃ due to the seepage of PVC monomers and additives. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling liquids, food, ultrapure liquids, slurries, gas and compressed air and vacuum systems. The production flow of the PVC pipe is as follows: raw materials and auxiliary agents are prepared → mixed → transported and loaded → forced feed → tapered twin-screw extruder → extrusion die → sizing sleeve → spray vacuum sizing box → soaking cooling water tank → ink printer → caterpillar tractor → cutter raising cutter → pipe stacking frame → finished product detection and packaging. The mixing is to prepare dry mixed powder, and PVC resin, various auxiliary agents and additives in the formula are added into a high-speed thermal mixer for thermal mixing after being correctly calculated and accurately weighed. After reaching the specified temperature and time, the mixture is discharged into a mixer to be cooled, and a powdery mixture which has certain volume density, is uniform, loose and easy to flow is obtained and can be used for granulation of a single-screw extruder or direct molding of a double-screw extruder in the next procedure. At present the compounding mechanism of PVC powder is when using because compounding equipment itself is higher, and it is higher to lead to feed inlet 21 to get the position, causes the staff to feed and gets the difficulty to if adopt artifical material loading to produce raise dust easily and splash, get healthy to cause seriously to the staff and get the influence.
