Corn Cob Grit 90 mesh

Why Choose Corn Cob Grit 90 Mesh?

Unlike aggressive mineral or metallic abrasives, corn cob grit is a biodegradable, non-toxic alternative that eliminates the risk of embedding or surface profiling. Its angular, spongy structure provides a scrubbing action that lifts contaminants without scratching substrates. This makes it ideal for cleaning molds, dies, and precision components where surface integrity is paramount.

The 90 mesh grade is a fine particle size, optimized for applications requiring a smooth finish and the ability to reach intricate geometries. It is widely used in air blasting systems and can be an effective, single-pass media for light-duty cleaning tasks.

Key Features and Benefits

• Non-destructive cleaning: Removes dirt, grease, and carbon without etching, pitting, or changing the dimensions of the base material.
• High absorbency: The porous structure naturally absorbs oils and residues, keeping the work surface clean during blasting.
• Biodegradable and non-toxic: A safe, environmentally friendly alternative to chemical strippers and silica sand.
• Reusable: Depending on the application and contaminant loading, the media can be recycled multiple times, lowering operational costs.
• Consistent 90 mesh grading: Ensures a uniform finish and predictable performance across production batches.

Typical Applications

This organic grit is specified across multiple industries for precision cleaning and surface preparation tasks. Common applications include:

• Mold and die cleaning: Safely removes release agents, burnt-on rubber, and plastic residue from tire molds, injection molds, and die-cast tooling without damaging critical surfaces or edge details.
• Electrical component cleaning: Cleans commutators, armatures, and windings by stripping varnish and carbon deposits without harming wire insulation or laminations.
• Delicate metal finishing: Deburrs and polishes aluminum, brass, and other non-ferrous parts where a smooth, matte finish is required.
• Wood and composite restoration: Strips paint and varnish from wood, fiberglass, and composite surfaces without raising the grain or causing surface damage.

Selection and Handling Guidance

To achieve the best results with Corn Cob Grit 90 mesh, consider the following operational parameters:

• Blast pressure: Maintain a low blast pressure, typically between 2 to 4 bar (30-60 PSI), to prevent media fracture and maximize recycling potential.
• Nozzle distance: Keep a distance of 30-45 cm from the workpiece to balance cleaning speed with media breakdown.
• Moisture control: Store bags in a dry environment. Moisture can cause the organic media to swell or clump, leading to inconsistent feed and poor blasting performance.
• Dust extraction: While non-toxic, the process generates organic dust. Ensure your blasting cabinet or room has adequate dust collection to maintain visibility and operator safety.
