Abstract

The invention relates to a method for detecting and adjusting the dipping liquid level of a round tube containing epoxy resin, and relates to the field of material forming testing, comprising the following steps: injecting glue liquid into a mold, and when the quality monitoring system monitors that the quality reaches a set value, central processing The ultrasonic generator controls the ultrasonic generator to generate ultrasonic waves, so that the ultrasonic transducer generates mechanical vibration; at the same time, it measures the height of the glue liquid level, and then transmits the liquid level height signal to the central processor. Set three different glue impregnation speed calculation formulas, and adjust the glue liquid speed in the glue liquid impregnation pipe by changing the pressure applied to the glue liquid storage tank through the pressure controller, so as to obtain qualified impregnated aramid composite round pipe products. The invention has the advantages of improving the mechanical properties and electrical insulation properties of the aramid composite round pipe.

Description

technical field

[0001] The invention relates to the technical field of material forming testing, in particular to a method for detecting and adjusting the immersion liquid level of a round pipe containing epoxy resin. Background technique

[0002] Aramid fiber-reinforced epoxy resin composites have the advantages of lighter weight and higher strength than glass fiber-reinforced epoxy resin composites. Aramid composite round tubes are widely used in high-voltage switchgear in the power industry as insulation for transmitting mechanical actions and connecting high and low potentials. Tie rods play the role of key insulating structural members.

[0003] The poor interfacial bonding ability of aramid fiber and epoxy resin determines that the impregnation process of aramid fiber fabric and epoxy resin is very difficult. For the preparation of aramid composite pipe, the impregnation speed control of glue solution in vacuum environment determines the impregnation effect of aramid ...
