Sand Blasting Process on the Back of Stone
The sand blasting process on the back of stone is a method to enhance the adhesion between stone and cement mortar, which is especially important for wet-applied stones. This process involves attaching a layer of quartz sand and epoxy resin adhesive to the back of the stone to enhance the stone's strength and bonding force, while also providing certain waterproofing and protective effects.
The Role of Sand Blasting
Enhance Adhesion: The back of the stone treated with sand blasting does not need to remove the mesh, thereby enhancing the adhesion strength and waterproof performance with cement.
Increase Stone Thickness: Sand blasting can increase the thickness and strength of the stone, reducing damage during construction.
Sand Blasting Methods
Material Selection
Quartz Sand: Choose quartz sand with different whiteness according to the color and purpose of the stone.
Process Flow
Place Slabs: Place the stone slabs on the gluing table or production line.
Slab Reinforcement: Repair and reinforce slabs with severe cracks.
Slab Surface Cleaning: Ensure the surface to be sand blasted is clean and dry.
Laying Net: Lay fiber mesh on the back of the slab.
Adhesive Mixing: Mix epoxy resin adhesive according to the instructions.
Brushing Adhesive: Uniformly apply the mixed epoxy resin adhesive on the fiber mesh.
Sand Scattering: Scatter quartz sand evenly on the adhesive surface.
Curing: Cure the epoxy resin adhesive by natural drying or baking.
Collecting Slabs: Collect the slabs after the adhesive is completely dry.
Lamination: Add a plastic film between the sand blasted surface and the front surface of the slab to prevent friction.
Packaging: Package the sand blasted slabs.
Processing: Process the sand blasted slabs as needed.
Conclusion
The sand blasting process is an effective method to enhance the application effect of stone, especially suitable for occasions with higher requirements for bonding strength and waterproof performance. By selecting the right materials and precise construction processes, the quality and durability of the stone can be significantly improved.
