Glass Sand | LEKAR

For over a decade, LEKAR has been providing high-quality glass sand with a high SiO₂ content. This gives each LEKAR glass sand particle superior durability, enhanced hardness, and delivers more effective surface treatment performance compared to conventional industrial sand.

Glass sand is a product made from soda lime glass, free from lead and crystalline silica. Produced mainly in two shapes, rounded or spherical, glass sand enables significantly smoother and brighter surface finishing compared to angular abrasive materials.

When in use, glass sand particles are blasted at high velocity to clean and polish product surfaces without altering the dimensions of the components. With a reusability of up to 30 cycles, glass sand is not only chemically inert but also environmentally friendly.

Currently, glass sand is mainly utilized in industrial sandblasting systems for tasks such as grinding, polishing, smoothing, blending, surface finishing, deburring, and cleaning most types of materials. Commonly available sizes of glass sand include #50–70, #60–80, #70–100, and #120–200, with #60–100 being the most widely used size by technicians for fast and efficient cleaning.

Glass sand primarily consists of SiO₂. In natural conditions, it usually exists as inert granules and is extracted through processes such as screening and washing.

The typical composition of glass sand is as follows:

Glass sand is considered safer than other abrasive media. Additionally, it is an excellent substitute for silica sand, which is banned in many countries.

The main advantages of glass sand include:

• Used for metal surface treatment during processing as well as overall cleaning while maintaining the original dimensions of the items after blasting.
• Provides balanced cleaning performance, effectively removing dirt and rust without damaging or deforming the surface.
• Environmentally friendly, available in various sizes, and reusable up to 30 times.

Glass sand is mainly used for cleaning metal workpiece surfaces, polishing, and enhancing the aesthetics of even complex and angular parts. Common applications include:

• Removing defects such as paint, varnish, scratches, rough spots, and carbon buildup.
• Cleaning surfaces like hard chrome, chrome plating, iron, steel, stainless steel, and machine engine parts such as cylinder heads, pistons, and valves.
• Improving corrosion resistance of machine components such as springs, turbines, and gears.
• Cleaning and enhancing the aesthetics of products without causing deformation.
• Enhancing anti-reflective coating on specialized tools such as surgical instruments, electronic device surfaces, and automotive windshield wipers.
• Polishing parts for automobiles, motorcycles, aircraft, and many other uses.
