Nitrogen Use in Aerosols                     Introduction An aerosol is any such substance enclosed under pressure and released as a fine spray by the means of a propellant gas. Common examples of aerosol products include deodorant sprays, pesticide sprays, hair sprays, shaving foams and the like. Components of an Aerosol An aerosol formulation mainly consists of two components, namely: (1 the product concentrate, and 2) the propellant. The product concentrate is the actual product, the active ingredient in the aerosol, combined with other additional ingredients and co-solvents which are there to make a stable and efficacious product. The product concentrate can be a solution, suspension, emulsion, semisolid or powder. The propellant is the gas which provides the force to expel the product concentrate from the container and is also responsible for the delivery of the formulation in the proper form (i.e. spray...

Nitrogen Application in Nylon Manufacture Introduction Nylon is actually a family of synthetic polymers, which can be processed into fibers, films or shapes. It is because of this thermoplastic’s silky property that made it the world’s first commercially successful synthetic thermoplastic polymer. Major uses of nylon include, but are not limited to fabrics, cookware and plastic fasteners and machine parts. Out of these, their application in manufacturing fabrics is the largest. Nylon fibers are woven together to form a silky, lightweight fabric. The reason for the popularity of this fabric is that it is resistant to abrasion, is a quite strong synthetic fiber, resists mildew, available readily and is relatively cheap. Application of Nitrogen in Nylon Manufacture Large-scale nylon manufacturers usually have nitrogen generators or nitrogen plants available on their premises, as nitrogen is an integral part of the production of various types of nylon. Nylon is form...
