What is Blasting Sand?
Blasting sand consists of special sands produced to remove rusted surfaces, corroded surfaces, and old paint, as well as to shape glass and marble, and to prepare surfaces for new coating applications. Although it resembles regular sand, it is structurally different and specifically manufactured for this purpose. It is made using distinct, specialized materials with different application areas, such as silica, basalt, and grit. It is generally used on metal surfaces, wooden floors, spare parts, marble, and similar components.
Silica Blasting
Silica sand, produced in various sizes, is preferred for blasting thin sheet metals up to 1 mm, and for thick sheet metals within the range of 1-3 mm.
Silica sands are generally yellow, gray, beige, and white. You can obtain every color and size from our company, processed through washing, screening, and drying in our modern technological facilities, ranging from 0-100 microns to 100-120 AFS down to 10-15 AFS, and from 50 microns up to 1 mm.
“Sandblasting is the process of striking the metal surface with blasting sand using high-pressure air. During this impact, while the sand abrades the metal surface at a micron level, it simultaneously scrapes and cleans all kinds of unwanted substances on the surface.”
Basalt Blasting
This type of sand, which can be described as low-dusting, is generally used in closed environments where the sand can be recycled and reused.
Grit Blasting
It is the type of abrasive with the lowest dusting and the highest blasting power. Technically, it is not sand but iron slag.
Usage of Blasting:
Basalt, iron grit, steel grit, and steel shot products are also widely used in the industry for blasting operations. Grit-blasting (raspa) sands are used in various dimensions depending on the technical specifications and corrosion rates of the metal. For high corrosion and thick materials, large-granule blasting products are generally preferred. For more sensitive blasting tasks and thin materials, fine-granule products should be utilized.
How is Sandblasting Done?
Blasting sands are subjected to a very special washing process, dried in natural gas ovens, and then classified according to the desired technical specifications. They are prepared in many different sizes starting from micro levels of 0-0.100 microns, up to 0.100-0.300 microns, 0.500-1 mm, 1-3 mm, and 2-3 mm, and are used in blasting machines, wet blasting, and spray blasting operations.
Our products are specifically purified from dust and oversized particles, ensuring that the blasted surface is smooth, easy, and practical to work with, while preventing the formation of clean yet hazardous dust in working environments.
As a result of the sandblasting process, the core of the metal is revealed, extending its service life. If the metal is painted immediately after blasting, the contact time of the surface with the air decreases, preventing oxidation. Thanks to its widespread and practical use today, it provides significant benefits. Since it is applied with high pressure, it is essential to take the necessary occupational safety precautions. Thanks to the surface profiling (anchoring teeth) created on the blasted surface, paint adhesion increases substantially. Large components are processed in big blasting rooms, while smaller parts are treated inside blasting cabinets. Sands are used in micro and macro scales, and there is no harm in recycling and reusing them several times.
Our silica sands, which are suitable for wet blasting operations, are highly efficient. They contribute quickly and economically to the rust and oil removal of sensitive parts, providing a high-efficiency working environment for our customers.
Usage Areas:
It is extensively used particularly in fuel power plants and gas plants for the insulation works of natural gas pipelines. It is not limited to paint and rust removal; it is the main raw material for operations based on dry or wet spraying onto the substrate surface, such as surface polishing, burr cleaning in the foundry industry, creating a decorative surface finish, and removing graffiti that causes visual pollution on walls.
- Multi-purpose blasting material.
- Rust removal.
- Paint stripping / removal.
- Scale removal.
- Surface roughening before coating/painting.
Quality and Logistics:
Our production is carried out within the framework of ISO 9001 standards. In order for the paint to adhere completely to metal and wood, the surface must be roughened so that the paint and primer cover each other perfectly. Today, the frequent implementation of surface preparation applications has gained great importance; thanks to the cleaning and renewal processes carried out on the surface, wear decreases and part life is prolonged. In steel materials, the mobile (on-site) blasting of tanks, ships, heavy industrial machinery, and parts that are difficult to dismantle and relocate is of vital importance. Since the investments made are highly costly and heavy, our sands contribute to the economy by preventing old assets from being discarded.
Our packaging method is offered for shipment to our customers in 25 kg packages and 1 - 1.5-ton big bags. Our blasting sands contain between 90% and 95% silicon dioxide by content, and quartz production is also available upon request.
