1, Material comparison
1. The rubber synchronous belt uses high-quality imported chloroprene rubber as the main raw material, mixed with a variety of auxiliary materials for different purposes, and the skeleton material is imported high-quality glass fiber cord.
2. Polyurethane synchronous belt is made of imported thermoplastic polyurethane material, which has high wear resistance and good movement ability.
2, Performance and appearance comparison
1. Polyurethane synchronous belt: Polyurethane synchronous belt is generally made of nylon wire or steel wire, copper wire as tensile body, polyester casting, with oil resistance, impact resistance, beauty and other characteristics.
2. Rubber timing belt: flexible, good water resistance (polyurethane PU is not water-resistant, high and low temperature resistance is not as good as rubber timing belt), polyurethane PU timing belt is suitable for use under static conditions at room temperature, otherwise rubber timing belt is suitable.
3, Polyurethane synchronous belt
Polyurethane synchronous belt is a kind of thermoplastic polyurethane material. It has high modulus, high strength, high elasticity, small permanent deformation, good winding property, excellent wear resistance, oil resistance, low temperature resistance, aging resistance, and can meet the requirements of medical and health care. The wear resistance of polyurethane synchronous belt is about 8 times of that of rubber synchronous belt under normal temperature environment, which is more suitable for food, food and health care than rubber synchronous belt Medical industry, clean production industry.
At present, polyurethane synchronous belt has gradually replaced rubber synchronous belt at room temperature. Polyurethane synchronous belt is widely used in computer embroidery machine, beverage machinery, colored glass manufacturing and other industries. The skeleton materials used are aramid wire rope and stainless steel wire rope.
4, Comparison of acid and alkali resistance
The acid and alkali resistance of rubber synchronous belt is much better than polyurethane synchronous belt.
5, Conclusion
In general:
The rubber synchronous belt has good flexibility and water resistance, polyurethane (PU) is not water resistant, and its reciprocating performance is relatively poor, and its high and low temperature performance is relatively poor;
Wear resistance: the wear resistance of rubber synchronous belt is worse than polyurethane synchronous belt at room temperature, polyurethane synchronous belt is more suitable at room temperature and static conditions, and rubber synchronous belt is more suitable for machinery working in harsh environment. Polyurethane synchronous belt and rubber synchronous belt complement each other and play the leading role in industrial belt synchronous belt for a long time now and in the future.
