1. Sandblasting,Rust Removal & Surface Treatment

- Reasons for Substitution:

- Environmental Protection: Quartz sand contains free silica, which can easily generate dust pollution during sandblasting. Long-term inhalation may cause silicosis. garnet sand does not contain free silica, meeting environmental standards, and can reduce occupational health risks.

- Safety: Quartz sand sandblasting may produce sparks, posing a safety hazard. Garnet sand is a natural non-metallic mineral and does not pose such a risk.

- Efficiency and Cost: Garnet sand has a higher hardness (7.5-8.5 vs. quartz sand 7). Its sharp, multi-faceted design improves sandblasting efficiency, saving 30% of abrasive material under the same conditions. It also has a longer service life and reduces overall costs.

2. Water Filtration and Environmentally Friendly Water Treatment

- Performance Advantages: Garnet filter media is wear-resistant, corrosion-resistant, and has strong pressure resistance, excellent pollution interception, and stable chemical properties. It can be used as a water treatment filter medium in the chemical, petroleum, and pharmaceutical industries. The particle size range is 0.25-5.0mm. - Collaborative Filtration: It can be combined with anthracite, quartz sand, and other materials to form a three-layer filtration system. Placed beneath the quartz sand layer, it serves as the final water quality control step, improving filtration accuracy.

3. Precision Manufacturing and High-End Applications

- Cutting and Grinding: Garnet sand has high hardness and excellent toughness, making it suitable for cutting, grinding, and polishing in high-end applications such as spacecraft, aircraft manufacturing, and shipbuilding. Replacing quartz sand can improve machining accuracy and surface quality.

- Coated Abrasives: The global coated abrasives market is growing rapidly. As a high-performance abrasive, garnet sand can meet the demand for high-end products in developed industrial countries, driving the industry's development towards precision.

4. Long-Term Trend of Substituting Traditional Abrasives

- Policy and Market Drivers:

- Environmental Pressure: Stricter global environmental policies are restricting the use of quartz sand due to pollution concerns. As an environmentally friendly natural abrasive, garnet sand continues to gain market share.

- Economical: Garnet sand is recyclable and has a lower long-term cost than quartz sand, meeting the needs of industrial manufacturing to reduce costs and increase efficiency.
