Floor grinding wheels are special tools used for floor treatment (such as concrete, stone, epoxy floor, etc.). They are usually installed on grinders or floor sanders to process the floor through rotational friction. Its main functions and application scenarios are as follows:
Core functions
Grinding and leveling
Remove uneven parts of the floor (such as bumps and burrs) to make the floor flat.
Used for pretreatment of concrete foundations to provide a uniform base for subsequent coatings (such as epoxy resins and curing agents).
Remove old coatings or contaminants
Remove residues such as old epoxy coatings, paints, glues, and oil stains.
Treat weathered, sanded or slightly damaged floors.
Coarse and fine grinding
Coarse grinding: Use high-grit grinding wheels to quickly cut the floor and repair larger defects.
Fine grinding: Fine grinding with low-grit grinding wheels to improve the smoothness of the floor.
Surface polishing
Use high-grit resin grinding wheels or polishing pads to make the floor mirror-like (commonly used for marble, terrazzo or cured floors).
Open pores
Through grinding, tiny pores are formed on the ground to improve the adhesion of subsequent coatings (such as sealants and penetrants).
Common types and applicable scenarios
Diamond grinding wheel
Features: high hardness, long life, suitable for hard floors (such as concrete and stone).
Uses: coarse grinding, removal of thick coatings, and repair of severely uneven floors.
Resin grinding wheel
Features: good flexibility, suitable for fine polishing.
Uses: epoxy floor renovation, stone polishing, surface brightening.
Metal grinding wheel (silicon carbide/tungsten steel)
Features: strong wear resistance, suitable for fast cutting.
Uses: removal of metal scratches, heavy floor renovation.
Hybrid grinding wheel (diamond + resin)
Features: taking into account both cutting force and polishing effect.
Uses: medium-fine grinding, used in the transition stage.
Typical application scenarios
Concrete sealed and cured floor: penetrating curing agent after grinding to improve hardness and gloss.
Epoxy floor construction: Grind the base surface to enhance adhesion.
Old floor renovation: Remove damaged coating and re-polish.
Stone maintenance: Repair scratches and restore stone gloss.
Industrial floor maintenance: Treat oil stains and repair worn areas.
Precautions
Operation safety
Wear goggles and dust masks to avoid debris splashing.
Keep the equipment stable to prevent the grinding wheel from offsetting and causing damage to the ground.
Choose the right grinding wheel
Match the grinding wheel mesh according to the material of the ground (concrete, stone, epoxy) and the construction stage (coarse grinding/fine grinding).
Maintenance and care
Clean the debris on the surface of the grinding wheel regularly to avoid clogging.
Check the wear of the grinding wheel and replace it in time to ensure efficiency.
Summary
Floor grinding wheels are an indispensable tool in floor construction. Through the combination of different meshes and materials, the whole process from basic treatment to fine polishing can be completed, which directly affects the final quality and service life of the floor. The selection needs to be made in combination with ground conditions, construction objectives and equipment compatibility.
