Characteristics of garnet rock sand
Garnet sand is a natural abrasive processed from garnet ore, with the characteristics of high hardness, high temperature resistance, and stable chemical properties. The molecular formula of garnet sand is A3B2(SiO4)3, and the appearance is crystalline particles with various colors, including red and green. According to its source, it is divided into garnet sea sand, garnet river sand and garnet sea sand. So what are the characteristics of garnet rock sand?
The characteristics of garnet rock sand are as follows:
1. Physical properties
High hardness and wear resistance
The Mohs hardness reaches 7.5-8.0, which is far higher than traditional materials such as quartz sand and sea sand. It is not easy to break during the blasting process. Even after breaking, new angular particles will still be produced, and it can be recycled more than 20 times. Unique particle structure
It is a nearly cubic particle with clear edges and corners, and has strong cutting and grinding capabilities. After sandblasting, it can significantly increase the roughness of the metal surface and improve the adhesion of the coating. High density and strong impact
Density is about 4.0g/cm³, more sand particles are sprayed per unit time, and the cleaning efficiency is higher.
2. Functional advantages
Environmental protection and safety
It does not contain harmful substances such as free silica, has little dust and is recyclable, and meets environmental protection requirements.
Stability and self-sharpening
The particle size and shape are stable during long-term use, and the particles will continue to form new sharp edges during cutting to maintain efficiency.
3. Wide application range
Industrial field
It is used for metal rust removal, sandblasting pretreatment, water jet cutting, etc., and is also suitable for ceramic and glass polishing.
Other fields
It can be used as gardening paving materials, beauty scrub ingredients, and even for jewelry design.
4. Other characteristics
Various colors
Naturally formed colors include orange-red, wine red, pink, etc., which are both functional and aesthetic.
Chemical inertness
It is stable in nature and not easy to react with other substances
