Precautions for initial use of uhmwpe truck liner
Ultra-high molecular weight polyethylene truck liner has the best impact resistance, good corrosion resistance, excellent chemical resistance, lower density than other thermoplastics, low friction coefficient, superior release properties, ultra-low water absorption, and extreme Good electrical insulation and antistatic properties, moderate mechanical strength, rigid creep resistance, excellent machinability, continuous naturalness, and good resistance to high energy radiation.
Uhmwpe truck liner as a new type of engineering plastic, polyethylene liner provides a variety of excellent performance in one, wear-resistant plastic crown, four times higher than nylon 66 and PTFE, higher than carbon steel 6 times, the impact strength is the first of the plastic, twice the PC, 5 times the ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ° C).
When using uhmwpe truck liner for the first time, please observe the following instructions and precautions:
- For the first time, the material in the silo is stored to two-thirds of the capacity of the entire warehouse, and then discharged.
- During operation, always keep the material in the warehouse of the material entering and closing the material, and always keep the material storage in the warehouse more than one-half of the capacity of the entire warehouse.
- It is strictly forbidden to directly impact the liner.
- The hardness of the various materials is different. The material and flow rate must not be changed at will. If it needs to be changed, it should not be greater than 12% of the original design capacity. Changing the material or flow rate will affect the service life of the liner.
- the use of ambient temperature, generally should not be greater than 80 ° C.
- Do not use external force to damage its structure and loosen the firmware at will.
- The time of the material in the static state of the warehouse should not exceed 36 hours (please do not stay in the warehouse for viscous materials to prevent agglomeration), and the material with water content less than 4% can prolong the rest time.
- When the temperature is low, please pay attention to the static time of the material in the warehouse to avoid the formation of frozen blocks.
