Reinforcing Fragile Stone Materials
For stones that are brittle, implementing effective reinforcement measures is crucial to ensure their integrity and safety during processing, transportation, and use. Here are some common methods for reinforcing stone materials:
1. Back Mesh Reinforcement
Back mesh reinforcement involves adhering a high-strength fiber mesh to the back of the stone with epoxy resin to enhance the overall strength of the slab. This technique is suitable for various types of stones, including marble, granite, limestone, and onyx.
Process Details:
Mesh Specifications: Typically, the mesh size is 5×5mm.
Mesh Width: Varying from 1.2—1.8m.
Curing Time: Requires 6~9 hours at room temperature, which can be accelerated by heating.
2. Surface Penetration Reinforcement
For stones with micro-cracks, surface penetration reinforcement can effectively improve their strength to withstand subsequent processing and use.
Process Details:
Infiltration Adhesive Selection: High-strength epoxy resin AB glue is used.
Curing Conditions: Requires 4~6 hours at room temperature, which can be shortened by high-temperature curing treatment.
Color Matching: Adjust the color of the glue according to the stone color to ensure no visible traces after reinforcement.
3. High-Pressure Injection Reinforcement
High-pressure injection is a method of reinforcing stone by injecting specially formulated adhesive into the stone's interior, which solidifies and strengthens the overall structure of the stone.
Process Flow:
Rough Stone Pretreatment: Clean the stone surface to remove dirt and debris.
Crack Sealing: Install and seal the crack with glue nozzles.
Adhesive Preparation: Prepare an appropriate amount of sealing adhesive to ensure thorough crack sealing.
High-Pressure Injection: Use specialized equipment to inject adhesive into the stone interior.
Curing: Allow to set and cure to ensure the adhesive fully solidifies.
4. Conclusion
High-pressure injection reinforcement technology is suitable for solving the damage to rough stones caused by general permeable cracks. It features automation and constant pressure injection, low labor intensity, and low cost, achieving high efficiency, and high benefits. This technology has been promoted in the global market and has received unanimous praise.
