Sodium silicate - Wikipedia

Sodium silicate is a generic name for chemical compounds with the formula Na 2x SiO 2+x or (Na 2 O) x · SiO 2, such as sodium metasilicate Na 2 SiO 3, sodium orthosilicate Na 4 SiO 4, and sodium pyrosilicate Na 6 Si 2 O 7.The anions are often polymeric.These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.

How paint is made - manufacture, making, used, components ...

The first step in making paint involves mixing the pigment with resin, solvents, and additives to form a paste. If the paint is to be for industrial use, it usually is then routed into a sand mill, a large cylinder that agitates tiny particles of sand or silica to grind the pigment particles, making them smaller and dispersing them throughout the mixture.

Process for Solvent Extraction of Bitumen from Oil Sand ...

Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of bitumen from Athabasca oil sands was investigated. In this process, oil sand is mixed with light hydrocarbon solvents, and the solvent–bitumen solution is separated from the mineral solids by centrifugal ...
