Processing Guide
Recommended Processing Parameters
1
Radiation measurement
- Recommend to irradiation dose 10-12 mrad, according to the different wire diameter and irradiation to choose the appropriate measuring equipment, in order to achieve the best performance.It is recommended to control the thermal extension within the range of 15% -25%。
2
Storage
- Package: 25kg per bag, Alumni-plastic inner, Kraft paper outside.
- Storage: no rain, no direct sunlight. Dry it at 60℃～70℃ about 4 hours if the material was storage more than 3 months before used.
3
Suggestion for processing
- The compression value of extrusion screw should be 1.2~2.0
- The time of material heated in the barrel should not exceed 10mins, or it maybe decomposed.
