Epoxy insulating pipe is made of electrician's alkali-free glass fiber cloth impregnated with epoxy resin and processed by baking and hot pressing in a forming mold. The circular rod has a high mechanical function. The appearance of the epoxy pipe should be smooth and free of bubbles, oil and impurities. Color unevenness, a little rubbing, etc. are all within the promised scale. Epoxy pipes are used in the insulation layout of electrical equipment, humid environment conditions and transformer oil.

what is the key manufacturing steps that affect the performance of epoxy insulated pipe？ The epoxy pipe processing manufacturer will briefly introduce it.

1. Manufacture 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, mix and dissolve, and store it in the glue tank under the condition of 80-85℃. .

2. The glass fiber is looped on the metal circular core mold, the longitudinal loop angle is 45°, and the fiber yarn bandwidth is 2.5mm. The fiber layer is: longitudinally surrounding 3.5mm thick + circumferentially surrounding 2 layers + longitudinally surrounding 3.5mm thick +2 layers of hoop surround.

3. Scrape the resin glue liquid to make the glue content in the fiber surrounding layer count as 26%.

4. Put a thermally shortened plastic pipe on the outer layer, blow hot air to shorten it and wrap it tightly, and then surround the outer layer with a 0.2mm thick and 20mm wide glass cloth tape, 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. Demoulding, shovel the glass cloth tape of the watch, and then perform post-processing according to the demand.

Epoxy insulating pipe is a commonly used electronic and electrical insulation material. It is resistant to high voltage, corrosion resistance, high temperature resistance, high strength, and good electric heating function. It can be operated at 230KV for a long time without fatigue, and the damage torque is greater than 2.6KN·m. In the environment, it can also be used normally.
