Production Description:
UHMW gear has great properties:
1. Extremely high wear resistance
UHMW gear has 3 million or more molecular weight, the smallest wear index, which makes UHMW gear have a very high capacity of anti-sliding friction. Its wear resistance is 6.6 times higher than normal alloy steel, 27.3 times that of stainless steel, 17.9 times that of phenolic resin, 6 times that of nylon 6, 4 times that of PE, and it increases the life of the implement substantially.
2. Very high impact resistance
Of the existing engineering plastics, the value of the impact toughness of UHMW gear is the highest, and many materials will crack, break, split or surface stress fatigue in the explosion of serious or repeated impact. UHMW gear will not damage by cantilever beam impact test according to ISO 9001 standards, and can bear strong external impacts, internal overload and pressure fluctuation.
3. Corrosion resistance
UHMW gear is a kind of structure of saturated molecules, so its chemical stability is very high. UHMW gear can withstand the erosion of potent chemical substances, and UHMW gear is not subject to corrosion in other lye and acid except for some mild acid at high temperature outside.
4. Good self-lubrication
UHMW gear contains the waxy substance itself, and its self-lubrication is very good. The frictional coefficient (196n, 2 hours) is only 0.219mn/m (ISO9001), so its self-lubrication is better than steel or brass with oil lubrication.
5. The unique resistance to low temperature
The resistance of UHMW gear to low temperature is excellent, and its impact resistance and anti-abrasion can't change basically at minus 269 degrees centigrade. UHMW gear is the only available engineering plastics can work at temperatures close to absolute zero. Meanwhile, the adaptable temperature range is large, and it can be used within -269 to 80 degrees centigrade.
6. Not easy to form dirt
UHMW gear has excellent surface non-adhesion and surface smoothness due to its small friction coefficient and non-polarity.
7. Long life-span
The unsaturated genes of molecular chain are less, and its fatigue resistance strength is more than 500 thousand times, and its environmental stress cracking resistance is more than 4000h, which is twice more than the PE. UHMW gear can still maintain more than 70% mechanical properties after it is buried and used for 50 years.
8. Easy installation
The UHMW gear weight of unit length is only one-eighth of the steel material, which makes itself easier to load, unload, transport and install.
9. Some other characteristics
UHMW gear can also absorb energy, absorb noise and resist static electricity, and holds shielding ability to the electron. UHMW gear is also water-repellant.
