Extrusion device for polyimide production and using method thereof

Abstract

The invention provides an extrusion device for polyimide production and a use method of the extrusion device. The extrusion device for polyimide production comprises a bottom plate. Supporting columnsare fixedly connected to the two sides of the top of the bottom plate; an extrusion frame is fixedly connected to the tops of the two supporting columns; a supporting plate is fixedly connected to one side of the top of the bottom plate; a mixing box is fixedly connected to the top of one side of the supporting plate; and a machine box is fixedly connected to one side of the extrusion frame. According to the extrusion device for polyimide production and the use method thereof, the use number of electric heaters can be adjusted according to the humidity of raw materials; when the using numberof the electric heaters is increased, limiting rods are taken down, limiting blocks are extruded through elastic force of stabilizing springs, the limiting blocks drive the moving rods to move, the moving rods drive the electric heaters to move to make the electric heaters make contact with the extrusion frame, and raw materials are heated, so that the strength of the extruded raw materials is guaranteed, and the situation that the forming effect is affected due to high humidity of the raw materials is avoided.

Description

technical field [0001] The invention relates to the field of polyimide production equipment, in particular to an extrusion device for polyimide production and a use method thereof. Background technique [0002] Polyimide is one of the organic polymer materials with the best comprehensive performance. Its high temperature resistance is above 400°C, and its long-term use temperature range is -200~300°C. Some parts have no obvious melting point, high insulation performance, dielectric constant at 103 Hz is 4.0, and dielectric loss is only 0.004~0.007. It belongs to F to H. According to the repetition According to the chemical structure of the unit, polyimide can be divided into three types: aliphatic, semi-aromatic and aromatic polyimide, and can be divided into cross-linked type and non-cross-linked type according to the interaction force between chains. Polyimide refers to a class of polymers containing imide rings (-CO-N-CO-) on the main chain, among which polymers containi...
