Three-in-One Process for Wear-Resistant Liners: Small Ceramic Hot Vulcanization Technology – Drilled Fixation

1. Core components and structure

• Ceramic Rubber Liner: It consists of three parts:
  • ceramic layer: High-alumina ceramics (alumina content ≥ 92%), providing superb wear resistance.
  • rubber layer: Natural rubber or Styrene Butadiene Rubber (SBR) to cushion impact and reduce noise.
  • metal layer: Steel backplate with bolts (Q235 or wear-resistant steel) for easy installation and fixing.
• tripledevise: refers to ceramics, rubber, and metals that have been thermosulphurized throughmetallurgyOne-time molding, no adhesive between layers, high bonding strength.

2. Advantages of small ceramic tile design

• dexterity: Smaller ceramic blocks (vs. larger ceramics) can be adapted to small curved devices (e.g. elbows, cyclones) for a better fit.
• Anti-shedding: Damage to a single piece of ceramic does not affect the whole, and local replacement costs are low.
• Thermal stress resistance: Rubber expansion joints between small pieces of ceramic to avoid cracking due to temperature changes.

3. Key steps in the hot vulcanization process

1. surface treatment::
   • Roughening of ceramics by sandblasting, phosphating of sheet metal, application of two-component adhesive (e.g. CHEMLOK 205+238).
2. Positioning and Punching::
   • The hole diameter is 2-4mm larger than the bolt.
3. Vulcanization molding::
   • Layers are stacked and put into molds, vulcanized for 20 minutes at 150°C±5°C and 12MPa pressure, and the rubber is completely cross-linked to penetrate the ceramic gap.
