Characteristics of PS Balls
PS Ball is a superior abrasive with the following outstanding properties:
- Environmentally friendly and non toxic
- Stable Spinel molecular structure formed by super cooling molten slag in steel making process
- High strength and low abrasive rate
- High density and very low friability
- Very safe composition
- High compressive strength and hardness
- Durable , can be collected and reused
- Harder than copper and sand
- High coefficient of friction and resistant to slippage
- It has been proven to have higher efficiency than river sand for pollution removal
- Under normal conditions, it generates fewer dust exhaust than copper slag and garnet
PS Balls Applications
- Unlike the case of mineral abrasives like garnet, PS ball is entirely dust free and this renders it suitable for use in surface preparation, rust removal and ship building applications. It is also normally used in maintenance of ships.
- PS Balls find applications in oil storage tanks, bridge construction work, in construction of heavy steel structures, in oil rig platforms, and so on; mainly for purposes of cleaning and surface preparation and are used for cleaning welded areas in storage tanks before repainting.
- It can be used as an abrasive material, to clean material surfaces and prepare them for painting.
- The usual traits make PS balls ideal for use in blast cleaning applications, as they offer the right atomizing of materials with respect to size, density, hardness and durability.
- Because of its high bulk specific gravity of 2.42 Kg/l, precious slag balls are widely used as a counterbalance in many applications.
- PS ball is also used as a filtration medium as it is non-water absorbent and is very durable.
- Because of its nonslip properties, PS Balls can be used as covering on the road or as paving for concrete and asphalt roads. It adheres effectively with asphalt or concrete and can therefore be used as efficient repair or reinforcement material for various purposes.
