Chemshun Ceramics High Alumina Ceramic Polishing Rod for Textile Machinery
Alumina rod gets a excellent corrosion resistance. Long-term sunshine, rainfall, humidity or other whether factors do little effect and damage on the rod surface, not even ultraviolet ray can change the rod color. Meanwhile, alumina rod has acid and alkali stability, thermal stability, high machining strength and hardness. These advantages make sure that alumina rod are competent in severe operating condition.
>> Chemshun Ceramic advantages:
- High hardness Superior abrasion
- Corrosion and chemical resistance
- Light weight
- Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost
- Good fluidity: Smooth surface ensure the free flow of material without blocking
