First, the implementation of standards
GB/T12528, EN50264, NFF63826, TB/T1484
Second, the characteristics and uses
The series not only has excellent low smoke zero halogen flame retardant properties, and excellent extrusion performance, in ordinary PVC extrusion processing extruder , as long as the normal cooling device , extrusion processing speed can be accelerated. This series of product performance than similar foreign products . This series of products applicable national standard and Japanese standard 380KM / H EMU cables , single structure thin-walled locomotive line and multi-core wire insulation in thin-walled locomotive .
Third, the extrusion process
Moisture-proof plastic bags such as found in the failure , to be dried before use , using the blowing method , the drying temperature is 65 ℃, for at least 2 hours , heat the material to the extruder is appropriate. Available L/D18-25 the extruder screw compressor is relatively low, the feeding amount is large. Extruder each district should have a cooling control system, due to the difference between the actual temperature of the melt and the temperature table indicates the value varies between different types of extruder vary , each user should be used according to specific extruder case, selec the appropriate temperature.
The following temperatures can be used as reference for commissioning :
Head can hold the filter can also be used below 60 mesh strainer ; die extrusion or trombone type available .
Fourth, storage and transportation
Packing : net weight 25Kg or 1000Kg, moisture-proof plastic composite vacuum bag, packaging kraft paper bags or bags with .
Transport and storage : cable during transport should not be the sun and rain . It should be stored in clean, cool , dry , ventilated warehouse.
Light handling process should be moved with care . Cable shelf life of one year.
Fifth, the physical and mechanical performance indicators
