Liquid state component mixing and spraying device and processing method

Abstract

The invention discloses a liquid state component mixing and spraying device and a processing method. The spraying device is provided with supercharging metering pumps arranged in return pipes. The supercharging metering pumps can apply pressure to liquid in the return pipes to drive the liquid into spray nozzles to be atomized in a vacuum high-pressure mixing cavity and mixed. The liquid is mixedin a mist spray mode. The mixing effect is more uniform. The liquid is mixed in the vacuum high-pressure mixing cavity, and no bubbles can be generated in the mixing process. Various types of liquid are mixed in the vacuum high-pressure mixing cavity to form mixed liquor, and the mixed liquid is stirred through a stirring mixer, and the mixing uniformity is further improved. A corresponding liquidstorage tank and the corresponding supercharging metering pump are arranged on each return pipe and can be heated to the appropriate temperature according to properties of different liquid, and appropriate pressure is applied to the liquid storage tank and the supercharging metering pump, and the universality is improved. The liquid state component mixing and spraying device provided by the invention is high in liquid mixing speed, stable in liquid flowing and capable of meeting the requirements of a composite for wet process mold pressing process and improving the forming and manufacturing efficiency of the high-carbon fiber composite.

Description

Technical field [0001] The invention belongs to the technical field of material processing, and particularly relates to a liquid component mixing spray device and a processing method. Background technique [0002] Continuous fiber reinforced resin-based composite materials, especially continuous carbon fiber reinforced thermosetting composite materials, have high specific strength, high specific modulus, corrosion resistance, energy absorption and other characteristics, and have a wide range of applications in automotive, rail transit, aerospace and other fields. [0003] Traditional continuous carbon fiber reinforced thermosetting composite materials generally use vacuum assisted molding process (VARI), prepreg molding (PCM), resin transfer molding (RTM), autoclave, high pressure resin transfer molding (HP-RTM) and other processes Forming, long forming cycle, low production efficiency and high manufacturing cost restrict the popularization and application of carbon fiber reinforce...
