Black Walnut Powder Walnut Shell/hull Powder

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Abrasive Cleaning & Polishing: Designed for surface cleaning, deburring, and polishing with three grit options (20, 40, 46) to address varying abrasion needs.
  • Material Processing: Walnut shell grits provide eco-friendly, non-toxic abrasion for applications requiring gentle yet effective material removal or surface preparation.

Key features

  • 1. Material Technology

    • With natural walnut shell material, achieve eco-friendly abrasion without harming delicate surfaces. Unlike synthetic abrasives, walnut shell powder offers a biodegradable alternative for sustainable use.

  • 2. Performance Parameters

    • With multiple grit options (20, 40, 46), you can select the optimal coarseness for your specific application. Finer grits (e.g., 46) enable precision cleaning on sensitive surfaces, while coarser grits (e.g., 20) tackle tougher debris.

  • 3. Scenario Solutions

    • Designed for industrial blasting or food-safe cleaning scenarios where non-metal abrasives are required. Its granular consistency ensures uniform distribution, making it ideal for surface preparation in commercial or home environments.

  • 4. Interactive Design

    • The uniform grit size distribution allows for consistent performance across applications, reducing the need for frequent adjustments. Perfect for tasks like paint stripping, deburring, or light polishing.

  • 5. Certification Standards

    • Certified for food-grade compliance*, making it safe for use in food processing equipment cleaning or culinary applications where hygiene is critical.

  • Notes:

    • The product’s natural material and grit versatility position it as a sustainable, multi-use abrasive.

Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: Walnut shell grits offer 20% faster surface cleaning than traditional aluminum oxide in food-grade applications.
    • Precision Engineering: The Pro Model’s 99% particle uniformity ensures 30% less rework in high-precision polishing.
    • Sustainability: Natural walnut shell composition reduces landfill waste by 40% compared to synthetic abrasives.

  2. Version Selection Guide:

    • Base Model: Ideal for small-scale operations (e.g., light-duty cleaning in automotive workshops).
    • Advanced Model: Suitable for medium-scale industries requiring versatility (e.g., food processing equipment maintenance).
    • Pro Model: Recommended for heavy-duty applications (e.g., aerospace component polishing) where extreme durability and precision are critical.

*Pro Model’s chemical resistance exceeds industry standards by 3x, enabling safe use in corrosive environments like chemical plant maintenance. Pair its coarse grit (20) with stainless steel surfaces to remove rust without pitting.
