Introduction: Rainwater‚ in most cases‚ is the most pure available source of water‚ something which gives rainwater preference over other available sources of water but more importantly‚ roof drainage pollution is also caused by rainwater. In United States the average amount of rainfall across the country is 35″ and the amount of land that is affected by excess water capable of damaging homes and properties is around 20%. Some of the most common environmental and moisture problems that are faced

To synthesize electroconductive composites graphite nanoparticles were used as filler material in many insulating polymers‚ for example epoxy‚ polystyrene‚ poly(methyl methacrylate)‚ thermoplastic polyurethane and many others [8]. Such composites attracted significant attention

6. POLYMERS and elastomers Lecture no. 1 Objectives: Definition‚ Functionality‚ Classification of high polymers – based on origin‚ molecular structure. 6.1.1. DEFINITION: The word polymer is derived from the two greek words‚ poly and meros‚ meaning many and parts or units respectively. Polymers are macro molecules formed by linking smaller molecules repeatedly‚ called monomers. Examples: Polythene is formed by linking a large number of ethene (or ethylene) molecules together

Introduction The main purpose of root canal treatment is the elimination of microorganism from root canal system (1‚2). Microorganisms and their byproducts are regarded as the primary etiological factors of periapical diseases and pulpal necrosis (3‚4‚5). Microbial reduction obtained by mechanical instrumentation‚ irrigation‚ using intracanal medicaments and adequate filling of root canal (6). Failure of the root canal treatment is the result of persisting microorgansims in the root canal system

plastic-def. A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Plastics Characteristics Plastics are made from fossil fuels--petroleum‚ natural gas‚ coal--‚ wood and some plant materials‚ air‚ water and sometimes other common materials

Customers today demand higher quality and durability from the products they buy. Not only do they expect these products to perform well‚ but they want the finish to look good and resist corrosion for a much longer period of time. Powder coating is different from painting. There are no liquids or solvents. Therefore‚ it is the ultimate coating for environmental friendliness. Being dry‚ the powder overspray can be reclaimed for very high application efficiency. It uses heat to convert its state from
