What are the steps in the manufacturing process of epoxy glass fiber tube? The following epoxy glass fiber tube manufacturers will explain to you:

1. The preparation of glue. Heat the epoxy resin in a water bath to 85~90℃, add the curing agent according to the resin/curing agent (mass ratio)=100/45, stir and dissolve it, and store it in the glue tank under the condition of 80-85℃. .

2. The glass fiber is wound on the metal round core mold, the longitudinal winding angle is about 45°, and the fiber yarn width is 2.5mm. The fiber layer is: longitudinal winding 3.5mm thick + hoop winding 2 layers + longitudinal winding 3.5mm thick + 2 hoop windings.

3. Scrape the resin glue liquid so that the glue content in the fiber winding layer is calculated as 26%.

4. Put a heat-shrinkable plastic tube on the outermost layer, blow hot air to shrink and wrap it tightly, and then wrap a layer of glass cloth tape with a thickness of 0.2mm and a width of 20mm on the outer layer, and then send it to the curing oven for curing .

5. Curing control, firstly rise from room temperature to 95°C at a rate of 3°C/10min, keep it for 3h, then raise it to 160°C at the same heating rate, keep it for 4h, then take it out of the oven and cool it down naturally to room temperature.

6. Demould, remove the glass cloth tape on the surface, and perform post-processing as needed.

Epoxy glass fiber tube is a commonly used electrical and electronic insulation material. It is resistant to high voltage, corrosion resistance, high temperature resistance, high strength, and good electrothermal performance. It can work for a long time under 230KV without fatigue, and its breaking torque is greater than 2.6KN·m. It can also be used normally in hot and humid environments.
