Polyester Resin impregnated Fiberglass banding tape
Polyester Resin impregnated Fiberglass banding tape is composed of alkali free twist glass fiber yarn t through a special high-temperature curing of unsaturated polyester resin impregnated. Banding tape has good flexibility and viscosity, opened the reticular structure, unwinding easily, no filoselle, no folds. It has high strength, impact resistance, high modulus, low elongation, no hysteresis and no eddy current loss of performance, which is the motor, transformer and arrester ideal binding material.

1¡¢Non-woven belt is divided into class H, class F£¬Parallel non latitude belt is class B, class F¡£
2¡¢The thickness is divided into 0.17mm, 0.3mm, 0.33mm; width of 6mm - 50mm; length of 50m - 200M (drum roll length 1500 meters - 2000 meters).
3¡¢Non latitude belt is divided into polyester resin impregnated and epoxy resin impregnated, polyester type storage period
4¡¢High tensile strength, thickness 0.3mm varieties can reach more than 1500N/cm¡£
5¡¢The curing time is short, the temperature of 155 ¡æ only 4 - 5 hours (continuous curing).
6¡¢High electrical strength, each mm thick parallel winding layer is greater than or equal to 12KV¡£
7¡¢Long storage period, the above 25 ¡æ for up to 6 months (epoxy type was 3 months), is favorable for storage, avoid waste¡£
8¡¢Retreat with easy, high utilization rate¡£
¶þ¡¢Instructions£º
1¡¢Non latitude belt should be stored at room temperature. The temperature is higher than 30 ¡æ, should be stored in the refrigerator¡£
2¡¢To detect non latitude belt performance (measured volatile content) should be 1 hours out in the plastic bag¡£
3¡¢Non-woven tape is removed from the refrigerator before use, should let it in the plastic, room temperature after 24 hours..
4¡¢Non latitude belt in the use process, such as tension unevenness or binding is not smooth, easy to cause the bifurcation. So we suggest it will not continue to use the latitude belt after finishing the entire disc.
5¡¢With no binding material is best performed at room temperature, but the heat binding effect is better¡£
The binding method of thermal state£º
A. Preheating the banding artifacts, the preheating temperature is at 80 ¡æ, time is about 1 hours¡£
B. Preheating non latitude belt: the non-woven tape at 40 ¡À 5 ¡æ oven for about 20 minutes, remove the use (Preheat the non latitude belt should not be too long, the temperature should not be too high, to avoid premature curing, the preheated non latitude belt to run out of time)¡£
6¡¢Binding tension ¡Ü 1000N/cm (0.3mm thickness), binding speed to 10m per minute - 15m is preferred¡£
7¡¢Lashing at the end, should be locked, preventing loss of tension applied, non latitude belt loose cause fastening (the end into inner layers of non-woven belt, to press)¡£
8¡¢The proposed piecewise curing: 80 ¡æ for 1 hour, 120¡æ for 1 hour, 155 ¡æ for 3 - 4 hours, (continuous curing, not including the workpiece heating time) traction motor, motor suggested curing more than 6 hours.
9¡¢If you want to finish the non latitude belt curing and leaching paint drying at the same time of heat treatment, need to do the experiment, determine the drying varnish on the curing of non-woven tape without obstruction¡£
10¡¢Use manual binding process, need of resin content, much volatile of the non latitude belt . |
