Abstract

The invention discloses an equipment for preparing polyvinyl chloride, which comprises a stirring chamber and a stirring device arranged in the stirring chamber, the stirring device includes a stirring shaft, a stirring paddle arranged on the stirring shaft and a stirring paddle for driving the stirring A driving member for rotating the shaft; the stirring paddle is provided with a turbulent channel for guiding the fluid to flow during the rotation of the stirring paddle to generate turbulent flow in the stirring chamber. In the present invention, through the setting of the turbulent channel, the stirring device can be in a state of turbulent flow in the stirring chamber when the stirring device is working, so that the materials are fully impacted, the materials are mixed evenly, and the stirring effect is good; the prepared product can be effectively improved. Improve the performance of polyvinyl chloride, improve the impact resistance and bending resistance of polyvinyl chloride.

Description

technical field [0001] The invention belongs to the technical field of polyethylene processing, and in particular relates to equipment for preparing polyvinyl chloride. Background technique [0002] Polyvinyl chloride (pvc) is a plastic whose output is only lower than that of polyethylene (PE) in the prior art. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. [0003] The traditional preparation process for polyvinyl chloride is usually to uniformly mix the materials through a stirring device, and then extrude them through a molding machine. However, the existing mixing equipment has a poor mixing effect on materials. In the polyvinyl chloride produced by stirring, the mixing uniformity between each material is low, which greatly affects the performance of polyvinyl chloride. Its impact resistan...
