Properties of Moulding Materials/Sand Permeability

The commonly used moulding materials in foundries are moulding sand, sand binders, and sand additives. The main constituent is moulding sand, so generally moulding sand is referred as a moulding material. The mould material should have certain qualities, and it depends on the processing properties of moulding material.

Oil Sands Geology the Properties of Bitumen Oil Sands

Although all oil sands contain heavy, complex hydrocarbons, their physical properties can vary. The Athabasca oil sands found in Alberta are water-wet, meaning a layer of water is thought to coat the bitumen and solids. This water facilitates the separation of the bitumen from the sand using water-based gravity separation process.

Pros and Cons of different types of Casting Processes

Plaster Casting. Plaster casting is a casting process with similarities to sand casting. Instead of using sand in the process, a mixture of water, gypsum and strengthening compounds are used. Advantages. Plaster casting is capable of delivering a closer dimensional tolerance than sand casting is able to. It delivers a smooth, as-cast finish.
