Reactive Sand
Reactive sand is an abrasive, free flowing material which can be used to form molds and patterns, repair damaged sand molds, protect surfaces and components and improve the life of sand molds. Reactive sand is made up of particles that are graded by size, shape, or composition and then treated with a coating or bonding agent to improve bonding and enable the particles to remain in place without shifting or becoming out of kilter. This ensures the sand does not misshapen or move during the casting process.
Reactive sand can be used for a variety of casting applications, including sand casting, molding and pattern making. When used in sand casting, the reactive sand moulds are placed in the casting chamber and a molten material is added. As the molten material cools and solidifies, it adheres to the mould cavity and the reactive sand strengthens the integrity of the mould. In addition, reactive sand can improve the pressure resistivity of the mould and reduce wear on the mould.
Reactive sand is also used in foundry and thermal-spraying applications. As the material is fired at high temperatures, the coating or agent melts, forming a strong bond with the particles. This bond helps to keep the particles in place during the thermal-spraying process, preventing them from being scattered away.
Reactive sand is also used as a protective coating on steel and other metal components. This allows the reactive sand to cover the surface of the metal, protecting it from corrosion and other damage. The reactive sand also helps to reduce contact with acids and alkalis which can corrode or degrade the metal.
Reactive sand has many advantages over traditional sand casting methods. It is simple to use, can provide increased accuracy and precision, and can be used to cast intricate and detailed shapes. In addition, its chemistry and properties allow the reactive sand to withstand higher casting temperatures while providing greater dimensional stability.
Reactive sand is an extremely versatile and effective material which can improve the life of sand molds, protect metal surfaces and components, and reduce wear on moulds in the casting process. It is used in a wide variety of industrial applications, from sand casting to thermal spraying, but it is most commonly used to produce patterns for complex metal parts. Reactive sand is a great choice for anyone looking for an effective and reliable casting or protective coating material.
