VARTM process resin flow control system and method

Abstract

The invention discloses a VARTM process resin flow control system and method.The VARTM process resin flow control system comprises a bottom plate, melting equipment, conveying equipment, stirring equipment and flow control equipment, the melting equipment comprises a box body, the box body is welded to the top of the bottom plate, a feeding port is formed in the outer wall of one side of the box body, a feeding groove is welded to the outer wall of one side of the box body, and an electric heating plate is welded to the inner wall of the box body; and holes distributed at equal intervals are formed in the electric heating plate, a filter screen in sliding connection with the inner wall of the box body is arranged below the electric heating plate, a threaded groove is formed in the outer wall of the top of the box body, and the control method comprises fixed installation, system no-load detection and system load detection. The electric heating plate works to heat and melt resin, a cutting blade cuts the resin and accelerates the resin melting speed, a stirring shaft stirs the melted resin and keeps the resin fluidity, a gear motor drives a baffle to rotate, the resin flow is changed according to needs, operation is convenient, time is saved, the maintenance cost is lower, and the production cost can be saved.

Description

technical field [0001] The invention relates to the technical field of VARTM process resin, in particular to a VARTM process resin flow control system and method. Background technique [0002] The relative molecular weight is uncertain but usually relatively high, and it is solid, medium solid, pseudo-solid, and sometimes liquid organic substances at room temperature. It has a softening or melting temperature range, has a tendency to flow under external force, and is often shell-shaped when broken. Broadly refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents. According to the source, it can be divided into natural resin and synthetic resin; according to the characteristics of its processing behavior, it can be divided into thermoplastic resin and thermosetting resin. Resin is the main raw material for making plastics, and it is also used to make coatings, adhesives, insulating materials, etc. It is widely...

Problems solved by technology

[0003] The VARTM process is one of the resin production processes. It is assisted by the traditional RTM plus vacuum method. However, the structure of the existing VARTM process resin flow control system is too complicated, and the system maintenance cost is high, resulting in an increase in resin production costs. It is easy to oxidize and solidify during the flow process, resulting in system failure
