Wear-resistant ceramic rubber composite liner丨Three in one丨DaCeramic seamless

Ceramic Rubber Liner-Three-in-One-Large Porcelain Seamless Hot Vulcanization Process-With BoltsIt is a compositeabrasion resistant materialThe following are commonly used in themines,electrical power,metallurgical,metallurgyThe lining of equipment in the construction and other industries to resist material scouring and abrasion. The following is a detailed analysis of the technology:

1. Core components and structure

• Ceramic Rubber Liner: It consists of three parts:
  • ceramic layer: High Aluminum Ceramics (aluminum oxide(content ≥ 92%), providing superb abrasion resistance.
  • rubber layer: Natural rubber orstyrene-butadiene rubber(SBR), cushioning impacts and reducing noise.
  • metal layer: Steel backplate with bolts (Q235 or wear-resistant steel) for easy installation and fixing.
• tripledevise: It refers to ceramics, rubber and metal molded in one go through the hot vulcanization process, with no adhesive between layers and high bonding strength.

2. Large Porcelain SeamlessHot Vulcanization Process

• Large Ceramic Tile Design: Larger ceramic block sizes (e.g. 40 x 40mm or customized) reduce seams and reduce the risk of material jamming.
• seamlessness: The ceramic blocks are filled with rubber, which forms an elastic seal after hot vulcanization to avoid material penetration.
• Hot Vulcanization Process::
  1. preprocessing: Sandblasting of ceramic surfaces, descaling of metal plates, application of special adhesives (e.g. Chemrock).
  2. Forming Vulcanization: Vulcanize at high temperature (140-160℃) and high pressure (≥10MPa) for 30-60 minutes to cross-link the rubber and tightly bond ceramics and metals.
  3. reprocess: Trim the edges after cooling and check the bond strength.

3. Design with bolts

• Bolt TypeEmbedded countersunk head bolts (M12-M20), pre-embedded or special bolts welded to the steel backing plate (depending on the workpiece), vulcanized and molded with rubber.
• Installation Advantages::
  • Directly bolted, no welding required to avoid thermal distortion.
  • Replaceable monoblockslinerMaintenance is easy.
• anti-loosening measures: The head of the bolt is covered with rubber, which is not easy to loosen under vibration conditions.
