Epoxy laminated fiber glass cloth tube is made of KH560 treated electric non-alkali glass cloth soaked in epoxy resin and acid anhydride curing agent and baked in hot rolls.
Epoxy laminated fiber glass cloth tube is made of KH560 treated electric non-alkali glass cloth soaked in epoxy resin and acid anhydride curing agent and baked in hot rolls. The laminated fiber glass cloth tube made of epoxy anhydride not only has good mechanical strength, but also has outstanding electrical properties, lower dielectric constant and dielectric loss than similar products. They can also maintain good mechanical and dielectric properties at high temperature. The epoxy fiberglass tube has light color and good heat resistance. It can meet the requirements of F grade use at least, and it can also produce H grade products. The Epoxy laminated fiber glass cloth tube is suitable for F and H grade motors and 3 phase dry type power distribution transformer as insulation structure.
Epoxy laminated fiber glass cloth pipe is made of laminated glass fiber cloth after being rolled at high temperature. The core of the rolled laminated pipe is an important tool for the production of laminated pipe. Its dimension accuracy directly affects the accuracy of the inner diameter of the laminated pipe, and its surface roughness directly affects the roughness of the inner wall of the laminated pipe.
In the production of epoxy laminated fiber glass cloth tube, when the adhesive is in the molten state on the hot roller at 180 ° C , the heat will be immediately absorbed by the tube core, and the molten adhesive will get cool immediately and become brittle and hard, losing its elasticity and viscosity if a cold tube core is encountered suddenly, which will inevitably affect the poor bonding of the inner wall of the laminated tube. When baking, because the tube core is cold, it needs to absorb a lot of heat, which will make the inner wall heated bad. Then uneven internal and external heat will make thick wall pipe crack. Thin-wall pipe will bubble easily and layer. The process requires that the core temperature should be between 80 ℃ and 100℃.
Epoxy laminated fiber glass cloth tubes are used in a wide range of applications. They are mainly used for high voltage, low voltage, electrical appliances, motors, welding machines, compound voltage, mutual inductor, voltage regulator wire coil frame, bracket, screw insulation, fuse shell, oil circuit breaker screw barrel and mat rolls, etc. Epoxy laminated fiber glass cloth tubes have bright mechanical strength and good machining performance. Therefore, epoxy glass pipe is widely used in textile machinery, environmental protection equipment, life-saving equipment and other aspects as roller, drag stick, support frame, pulley, socket, gasket and bearing retainer, etc.
