Abstract

The invention relates to a screw assembly for nano-powder master batch processing. The screw assembly comprises a double-screw extruder and an extruder barrel arranged on the double-screw extruder. Two parallel screws (6) are arranged in the extruder barrel, and a plurality of screw parts of different specifications are installed on each screw (6). The screws (6) are symmetrically arranged in the extruder barrel and rotate in the same direction; by the adoption of the double-screw rotating extrusion mode, friction heat generated when raw materials are extruded is small, the screw meshing shearing effect on the raw materials is stable and uniform, and raw material mixing and plastic quality are good; due to double-screw meshing rotating work, the screw assembly does not affect the mechanical properties of the raw materials, energy is saved, and production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of powder processing equipment, and particularly relates to a screw combination used for processing nanometer powder master batches. Background technique [0002] The carbon fiber material contained in the nano-powder masterbatch is a new product developed in recent years. It is composed of a mixture of ultrafine powder material and polyacrylonitrile carbon fiber, and its strength can be as high as 250-560MPa, while the general ordinary powder material is usually only 12MPa. This powder material also has light weight, heat resistance, good flame retardant performance, etc. Advantages, suitable for various civil construction projects, is an excellent structural material, and can also be used in aerospace engineering. The process flow of carbon fiber material is: crushing and pre-homogenization; raw meal preparation and grinding; raw meal homogenization, screening and classification; preheating decomposition ...
