Product Description

 

Textile Ceramic shining mirror polish ceramic Yarn Guide Eyelet

 

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramic is generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.

The choice of Ceramic Eyelet for textile machinery has always been a critical part of cost effective fiber processing.With todays’ extremely fast production speeds, synthetic fibers and abrasive high-wearing technical yarns have led to ever-higher demands on ceramic guides.

 

 

Some of the most important properties of alumina Ceramic Eyelet are:

  • Wear resistance
  • Frictional characteristics of the guide surface
  • Chemical resistance
  • Fracture strength
  • Surface structure (not to damage the yarn)
  • Corrosion resistance Commonly used ceramic materials are corrosion resistant to most chemicals and are thermally stable.
