Detailed description of the crane support pads:
Ultra-high molecular weight polyethylene outrigger pads are stronger than previous wooden pads, iron pads are more wear-resistant and compressive, and they are lighter in weight, easy to handle, more convenient to use, increase work efficiency, and extend the use of pads life.
Performance of UHMWPE wear-resistant and compression-resistant crane support pads:
- The wear resistance ranks the highest in plastics, which is 4 times higher than nylon 66 and 6 times higher than carbon steel;
- The impact strength ranks first among plastics, which is 2 times that of PC and 5 times that of ABS, and can maintain high toughness at the temperature of liquid nitrogen (－196 ℃)；
- The friction coefficient is only 0.07-0.11;
- The impact energy absorption value is the best value among all plastics, and the noise reduction effect is very good;
- The chemical stability is very high, and it can resist the role of various corrosive media and organic media within a certain temperature and concentration range;
- Completely hygienic and non-toxic;
- Excellent corrosion resistance, low friction coefficient, small specific gravity, and good resistance to high energy radiation；
- Ultra-high molecular weight polyethylene is chemically stable and can withstand corrosion by various corrosive media such as acids, alkalis, salts, and organic solvents at a certain temperature and concentration range；
- UHMWPE is tasteless, non-toxic, odorless, non-corrosive, and has physiological circulation and physiological adaptability;
10. When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature drops to 140 ° C. Ultra-high molecular weight polyethylene can even be used under the action of liquid nitrogen, its use temperature can reach 269 ℃ below, still has a certain mechanical strength.
