In China, with the development of pressure gelation equipment and its continuous improvement under the Coal Research Institute, as well as the gap between local epoxy resin specialized for pressure gel and imported material increasingly narrow, pressure gelation process in the electrical insulation industry has also been expanded, and has played an irreplaceable role.
Pressure gelation technology is now successfully used in the production of high quality enclosed pole, cross-fluorinated sulfur load switch housing, transformers and other products.
Epoxy resin automatic pressure gel hydraulic APG clamping machine to produce the insulators as outlined below:
A certain percentage of epoxy resin speical for pressure gel, curing agent, fillers, colorants join the mixing tank. Stir 1 to 2 hours to mix material evenly and no bubbles in the sealed pot under a vacuum state (absolute pressure is less than 500Pa).
Pretreated epoxy resin mixture is injected into the APG mold preheating to 140deg with the help of compressed air or pressurized pump. The mixture is released from the mold after thermal gel forming and get semi-finished products.
Epoxy resin automatic pressure gel hydraulic APG clamping machine mold should be set aside suitable gap in a specific parting line surface in order to discharge the air from the mold in the process of injecting material. After the gel injecting into the mold, the epoxy resin due to rapid heating fill into the small gap, leaving the mold in a sealed state, so the material within the mold under pressure gradually gel to get a close texture product.
In order to make the mold parting line surface leaving some gap not only able to exhaust but also reliable seal, which require higher accuracy of the mold, especially for some of the complex structure of the insulators, the mold is with much higher accuracy requirements. In short, Pressure gel mold is equipped with a high technical content.
After injection, the products are transferred to the oven, and the finished products get dense and low internal stress after slow cooling under constant temperature of 140deg 10 hours.
Epoxy resin automatic pressure gel hydraulic APG clamping machine features:
Low power consumption
High operation efficency standards
Long life servies
