Low smoking zero halogen cable material granulator
The new energy charging pile low smoke halogen free cable material is the twin screw high speed, strong mixing and single screw low speed, low temperature, weak shear characteristics, the process of high degree of automation, pipeline operations, the dispersion effect is excellent, high yield, condition of clean, is the heat sensitive material, high shear mixing modified models. Low smoke halogen-free cable material granulator unique with slide of blowing die surface eager to head, the head part is cooled, single screw core cooling, effectively prevent the clay in the production process, yield increased significantly.
LSZH cable 1, The processing performance, can be formed on a common piston, screw-type injection molding machines, injection molding temperature: about 150-180 ℃, can be adjusted according to specific circumstances. Generally, the maximum temperature should not exceed 200 ℃.2,It is different between the actual temperature and the temperature table indicates the difference between the value of the melt value of the injection molding machine types are different, the user should set the appropriate temperature depending on the specific circumstances of the injection molding machine.
Extrusion process
- can be processed in ordinary PVC extrusion equipment, the equipment must have good temperature control device, screw diameter greater than 20:1, can adapt to the production of ordinary screw and BM screw extruder, screw and do not need to change the electrical power, is better than the ordinary type of screw extrusion, a high compression ratio can get a better surface and processing efficiency.
- Reference Extrusion temperature: Zone 1 Zone 2 Zone 3 Zone 4 Zone5 head 120 ℃ 135 ℃ 155 ℃ 165 ℃ 170 ℃ 170 ℃
- 3 temperature control equipment of temperature control system according to the error value, processing section, make appropriate adjustment speed of extrusion, the user can on the basis of each reference temperature and adjust the temperature of 10 DEG C to adapt to a variety of extrusion speed and extrusion surface.
Precautions
1, broken and materials may be used after drying, the remaining material immediately sealed to prevent moisture. Drying condition: drying oven at 70 ℃ 8 hours (material thickness 2-4cm), or vacuum-dried for more than 4 hours.
2, before use to ensure that the screw, barrel, feeding bucket completely clean, processing is prohibited to bring water and impurities.
3, the user can customize according to the needs of various masterbatch added suggested masterbatch added in a proportion of 0.2% to 0.8%; in order to achieve the best extrusion results, we recommend masterbatch added in the 70 ℃ oven drying 8 hours or more (the thickness of material 1-2 cm), or more than 4 hours and dried in vacuo.
4, 4, if the storage time of more than 2 months to use, it is best to pre drying, drying conditions: 70 degrees in the oven drying 8 hours or more (material layer thickness 2-4cm), or vacuum drying for more than 4 hours.
Packaging Storage
1, the plastic composite bag with plastic composite bag packaging, each bag is 25kg.
2, should not be exposed to the sun and rain in the transport process, in the process of handling should be handled with care, to avoid mechanical damage and other abnormal conditions of infringement, should be placed in a cool, ventilated and dry warehouse.
