Application Instruction of Banding Tape
|
|
|
|
Application
|
|
1、Banding tape should be stored in the condition of room temperature. If environment temperature is above 30℃, the products should be put in the freezer.
|
|
2、The testing of properties (for example: test volatile content) should be carried within one hour after the banding tape is taken from the plastic bag.
|
|
3、When applying the banding tape, keep it in the plastic bag at the room temperature for 24 hours after taking out from the freezer.
|
|
4、During the process of application, uneven tension and unsmooth banding would make the tape separation. You could continue to use after neatening the remaining pancake.
|
|
5、Banding process should proceed at the room temperature. Better effect will obtain if the process is put up at the heat condition.
|
|
Heat banding process is as follows:
|
|
A.Preheat the work piece at the temperature 80℃ for one hour.
|
|
B. Prereheat the banding tape at the temperature 40℃±5℃ for 20 minutes. Preheat can not be over the time to avoid the tape to be cured in advance,. The tape preheated should be used up once.
|
|
6、Certain tension should be applied to the banding tape. Tension is less than 1000N/cm for 0.30mm thick tape , The speed is good enough at 10m-15m /min.
|
|
7、 In order to prevent the loosen of the tape, its end should be locked when the banding work finished. Insert the end into inner layer of the tape and press tightly.
|
|
8、It is recommended to cure the finished banding work piece continuely at several stage: 80℃ for 1 hour; 120℃ for 1 hour; 155℃ for 3 - 4 hours. It needs 6 hours for tractor motor and industrial large motor ( above-mentioned exclude the time for work piece to reach the curing temperature).
|
|
9、 If you would treat dry process of varnish dipping and curing of banding tape together, it is necessary to do a trial to make sure that the dry process will not affect the curing of banding tape.
|
|
10、If you want banding process by hands, richer resin and higher volatile content type tape than normal of ours is suitable for you.
