What industries is industrial garnet as a sandblasting media used for?
Industrial garnet sand is widely used in the following industries as a sandblasting media due to its high hardness (Mohs hardness 7.5-8.0), sharp particles, environmentally friendly (free of free silicon), and recyclable properties:
Ship building and maintenance
Garnet sand is used for rust removal, scale removal and old coating cleaning of large steel structures such as hulls, decks, and cabins.
After garnet sand blasting, a uniform rough surface is formed, which significantly improves the adhesion of subsequent coatings and enhances anti-corrosion performance.
Transportation equipment manufacturing and maintenance
Aerospace: Garnet sand is used for surface cleaning, rust removal, decontamination and fine polishing of aircraft fuselages and parts (such as engine blades).
Automobile manufacturing: Industrial garnet is used for rust removal, burr removal, surface cleaning and preparation for spraying of car bodies, chassis, and parts (such as wheels).
Railway transportation: Garnet is often used for rust removal and maintenance of train carriages, locomotives and track facilities.
‌Heavy machinery and steel structure manufacturing
Garnet sand is often used for surface pretreatment (rust removal, scale removal, and removal of old paint film) of large engineering machinery, bridges, building steel structures, storage tanks, pipelines, etc. before painting.
Garnet provides a clean surface for welding areas.
‌High-end precision manufacturing
Garnet sand is used for surface cleaning, micro-burr removal, and precision polishing of precision metal parts (such as aircraft engine blades, medical device parts, and precision instrument parts). Because garnet has little damage to the substrate, it is suitable for high-precision requirements.
‌Petroleum and natural gas industry
Garnet sand is commonly used for anti-corrosion coating maintenance and surface pretreatment of offshore platforms, drilling equipment, oil and gas pipelines, and storage tanks.
‌Casting and molds
Garnet sand is used to clean the surface of castings. Residues such as molding sand and scale are removed.
Garnet sand is used as a casting release agent to reduce friction between castings and molds.
Garnet is often used for cleaning and maintenance of mold surfaces.
‌Building Materials and Decorations
‌Metal Building Materials: ‌ Garnet sand is used for matte treatment, cleaning and texturing of stainless steel, aluminum alloy and other building curtain walls and decorative components.
‌Stone: ‌ Garnet sand is used for cleaning, decontamination, matte or texturing of stone surfaces.
‌Glass and Ceramics: ‌ Garnet sand is used for fine polishing and cleaning of glass products (such as cathode ray tube glass shells, optical glass) and ceramic workpieces (such as electronic device housings).
‌Concrete: ‌ The concrete surface is roughened with garnet sand to increase the adhesion of subsequent coatings or coating materials.
‌Furniture and Wood Products
Garnet sand is used for surface cleaning, decontamination and texture enhancement of high-quality metal furniture and wooden furniture.
‌Core Advantages Summary
‌Efficient Cleaning: ‌ Garnet sand can completely remove rust, scale, old coatings and dirt.
‌High-Quality Surface: ‌ After garnet sandblasting, a uniform and appropriately rough clean surface can be formed, which greatly enhances the adhesion of the coating.
‌High precision:‌ Garnet sandblasting has little damage to the substrate and is suitable for precision parts processing.
‌Environmental protection and safety:‌ Garnet does not contain free silicon, has low dust hazard, and meets the requirements of green industry.
‌Economic and durable:‌ Garnet sand can be recycled many times, has a long service life, and has a low long-term comprehensive cost.
In summary, industrial garnet sand is a key environmentally friendly abrasive in the field of metal surface treatment (especially rust removal and pre-spraying treatment), precision machining, and surface finishing of hard non-metallic materials.
