Silt fencing provides a system of sediment control similar to bale barriers. The fencing material can be made of burlap or geotechnical fabric that is supported by wire stays fastened to posts. It is installed around a construction site as an erosion control measure. When the construction is complete, the silt fencing is removed.
Silver Brazing Alloys are basically alloys of silver, copper and zinc that contain 10 to 50 percent silver and melt at temperatures as low as 1175 degrees. Silver brazing alloys are used extensively in the manufacture of equipment for chemical plants and other industries where resistance to corrosion is important. The silver brazing alloys are widely used in the joining of the stainless steels. Silver brazing alloys require the use of special fluxes.
