An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing, which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface. The process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.Abrasive materials are hard cryst …

Medical oxygen regulators are precision devices which control oxygen pressures up to 2,000 and even 3,000 psig (per square inch gauge) and regulate this pressure to allow patients to receive the proper prescription of oxygen. Oxygen Conserving Devices and Regulators are pressure reducing devices designed to regulate or lower oxygen pressure from a cylinder to levels that can be safely used by the patient. A Regulator simply regulates the (free) flow from an oxygen cylinder.Oxygen regulat …

Shell Dot 4: Your Quality Brake Fluid IntroductionBrake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, and light trucks. It is used to transfer force into pressure and to amplify braking force. It works because liquids are not appreciably compressible.Shell DOT 4 Brake and Clutch fluid is long-lasting and has a low viscosity. It is suitable, especially for anti-braking systems, electronic stability control s …

Dispersants are chemicals that are sprayed especially on a surface oil slick, to break down the oil into smaller droplets that are distributed or spread over a large volume of water which are more readily mix with the water. Dispersants do not reduce the amount of oil entering the environment, but push the effects of the spill underwater. Dispersant contain compounds such as surfactant that lowers the interfacial tension of molecules with both water-soluble and oil soluble component, which …

Surface Preparation of Marine Vessels For CoatingCoating is the most cost-effective way of providing protection for corrosion and to prolong the lifespan of marine vessel and other offshore structures. Paint and preservative coatings can be found on both interior and exterior surfaces of a ship with separate areas being coated differently according to their particular kind of exposure. Before paint can be effective as an anticorrosive, the substrate to which it is to be applied must be thoroughl …

An alkyd is a polyester modified by the addition of fatty acids and other components. The term alkyd is a modification of the original name "alcid", reflecting the fact that they are derived from alcohol and organic acids. Alkyds are used in paints and in moulds for casting. They are the dominant resin or binder in most commercial "oil-based" coatings. Alkyd paint or oil based paint, is popular in applications that require a high gloss, durable finish. They are the most suitable choic …

Epochem Rust Remover is harmless, while effectively removing rust and tarnish from steel …

Epochem descaler is a chemical for removing lime scale (a deposit of calcium carbonate) from metallic surfaces. Descaling agents are typically acidic compounds such as hydrochloric acid that react with the alkaline carbonate compounds present in the scale, producing carbon dioxide gas and a soluble salt. Strongly acidic descaling agents are often corrosive to the eyes and skin.A scale is a coating or precipitate deposited on surfaces that are in contact with water. Water that contain …

Epochem Premium Transformer OilEpochem Premium Transformer Oil is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. Epochem premium transformer oil is most often based on mineral oil, but alternative formulations with better engineering or environmental properties are growing in popularity.Basic Requirements of …
