Core characteristics of wear-resistant ceramic sheets
Material composition: Alumina (Al₂O₃, purity 92%~99%)
Performance advantages:
High hardness: Rockwell hardness HRA≥85, wear resistance is more than 20 times that of manganese steel.
Corrosion resistance: Acid and alkali resistance, high-temperature resistance (some ceramics can withstand temperatures up to 1600℃).
Lightweight: The density is only 1/3 of that of steel, reducing the load on equipment.
Issue Phenomenon | Cause Analysis | Solution |
Local Ceramic Tile Shedding | Oil contamination on the substrate was not completely removed | Rework by re-sandblasting and using a degreaser for a second cleaning |
Brittle and Cracked Glue Layer | Incorrect mixing ratio or uneven mixing | Strictly weigh according to the specified ratio, and ensure mixing time is ≥3 minutes |
Ceramic Edge Chipping | No chamfering or buffer layer applied | Use ceramic tiles with R5 rounded corners for the edges, and install rubber edge guards |
Ceramic Lifting in High-Temperature Areas | The glue's temperature resistance is insufficient | Replace with inorganic glue or add an anchoring structure |
Installation process steps
1. Surface treatment
Cleaning: Remove oil, rust, and impurities from the surface of the equipment.
Polishing: Increase surface roughness and improve bonding effect.
2. Adhesive selection
Epoxy resin: Suitable for most working conditions, high bonding strength.
Polyurethane: Suitable for high-temperature environments, good elasticity.
Inorganic adhesive: Suitable for ultra-high temperature environments, good heat resistance.
3. Ceramic sheet pasting
Gluing: Apply adhesive evenly on the back of the equipment and ceramic sheet.
Pasting: Paste the ceramic sheet according to the designed position to ensure a tight fit.
Pressurization: Use a clamp or heavy object to pressurize to ensure a firm bond.
4. Curing
Room temperature curing: Usually takes more than 24 hours.
Heating curing: Curing can be accelerated in a high-temperature environment to improve bonding strength.
5. Inspection and trimming
Inspection: Check the bonding quality after curing to ensure no shedding or hollowing.
Trimming: Trim if necessary to ensure a smooth surface.
