Acid rain is best known for the damage it causes to forests and lakes. These compounds are transformed in the atmosphere, often traveling thousands of kilometers from their original source, and then fall out on land and water surfaces as acid rain.
These compounds are transformed in the atmosphere. When fossil fuels are combusted, acid-forming nitrogen and sulfur oxides are released to the atmosphere. The precursors, or chemical forerunners, of acid rain formation result from both natural sources - volcanoes and decaying vegetation - and man-made sources - primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion. Example: Performing chemical-resistance tests at elevated temperatures.Īcid rain refers to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Laboratory performance test of a container or coating to evaluate its performance in a shorter time interval than that required under actual service conditions. More costly than general purpose and impact grades of polystyrene. Tough, hard, rigid, opaque plastic easily fabricated by injection molding, extrusion and thermoforming. The design is fired, heated in a lehr, and becomes permanently fused.Īcrylonitrile-butadiene styrene (ABS). Employs screen printing to transfer glass frit (powdered glass colorant) to the surface of a bottle or glass container. Colored lettering or design of a ceramic nature fused onto bottles.
