Application of unidirectional binding tape
Unidirectional binding tape has excellent performance, which can be used on the motor to improve the performance, make the motor safe and reliable, and simplify the binding process. When the unidirectional weftless tape binding tape is used in transformers, it can improve the performance of transformers, reduce the shearing process of silicon steel sheet and the vibration and noise of the transformer. So the unidirectional weftless tape binding tape is widely used in national defense, chemical industry, electrical appliances, machinery and other departments. Such as: it is used to wrap high temperature and high pressure thin-walled shell, cylinder, high pressure vessels, etc. The electrical unidirectional weftless tape can also wrap several kinds of low pressure chemical pipe motor, electrical appliances, anti-magnetic alloy steel wire binding armatures. It can also be used for capacitors, electronic products, large and small DC motors, generators, traction motors, welding machines, hollow screw of transformer, fastening iron core and insulation parts of transformer and reactor.
Performance of unidirectional binding tape
Unidirectional binding tape and thin knitting tape are semi-dry predip tapes made of thermosetting resin impregnated with alkali-free glass fiber after silane surface treatment. The quality of unidirectional binding tape winding products is stable and reliable, the resin content is not affected by the winding tension, the tension can be accurately controlled in different winding layers, so that the products have the best strength and stiffness structure. The tensile strength of the finished product can be compared with that of alloy steel, but the specific gravity is only one fifth that of alloy steel.
Using method of unidirectional binding tape
There is no difference in the use of different binding tapes. In summer, take out from the refrigerator and leave at room temperature for several hours. Use it when the tape becomes soft. In winter, you can place the unidirectional binding tape in the oven to heat under 60-- 80℃ for half an hour to one hour. When binding, the binding speed should be controlled below 50 RPM and the binding swelling force should be 20-50kg /cm2. After winding out the specified thickness, it should be cured in the oven together with the object. The temperature should be kept for one hour at 90 degrees and ten hours at 130 degrees. Grade F is kept at 130 ° C for 2 hours and 150 ° C for 10 hours. B class F class H class weftless tape, shrinkage tape, thin knitting tape is stored below 30 degrees, the storage period is generally three months. It is strictly prohibited to collide in the process of storage and transportation. It is moisture-proof and sun-proof. Keep clean and dry.
Transportation and storage of unidirectional binding tape
Each transformer binding tape is sealed in a wooden case (carton) with a plastic bag. Stricter care should be taken to avoid collision, extrusion, heat, moisture and sunlight during transportation.
