Surface quality preservation

The quality of the environment is degrading continuously, due to the accumulation of various undesirable constituents. Water resources, the most important and useful components of the environment, are most affected by pollution. The ground and surface water at many places in the world are not suitable for drinking purposes, due to the presence of aesthetic and toxic pollutants. Therefore, the importance of water quality preservation and improvement is essential and continuously increasing. The most important toxic pollutants are inorganic and organic chemicals. Therefore, determination of these water pollutants at trace levels is essential in environmental hydrology. 

Surface engineering is a key technology for applications with plastics and composites. Consumers demand top quality, but do not see the consequences for the natural environment. In the future, product manufactiu-ers especially in automotive industry should cooperate to cut back exaggerated surface qualities as a contribution to the preservation of natural resources. 

If restoration or preservation is required, a professional is consulted to slow the deterioration, thus giving the work an extended life. With some works of art, this is difficult. Many modem works are made of materials that are difficult to preserve and restore, such as newspaper, poor-quality paint, and experimental materials that may be glued to the surface or mixed with the paint. Many pictures are painted on a poorly prepared surface using very heavy applications of paint in time, the paint will begin to fall off the canvas or other working surface. It is the task of the restorer to do whatever is possible to preserve as much of the work as possible. 

Wear resistance and tensile strength of rubbers and polymers are increased by the introduction of silica in the organic network. In order to preserve these improved qualities in wet conditions, however, the silica surface has to be modified to assure interfacial bonding.32...
