Oxidized Bitumen


Project Description

Oxidized Bitumen

In order for petroleum bitumen with high degree of softness to have elasticity even in cold, air is blown into it to oxidize. Blowing hot air into the pure bitumen in the last stage of the filtration process results in a blown bitumen (Rubbery Grade). In this process, hot air at a temperature of 200 to 300 ° C is blown into the bitumen chamber by perforated pipes. As a result of this process, the hydrogen atoms in the molecules of bitumen hydrocarbons combine with the oxygen in the air, and with the formation of water, polymerization takes place and bitumen with the properties of mineral bitumen is formed.

Oxidized Bitumen is producing in some different grades:

Oxidized Bitumen 115/15, Oxidized Bitumen 85/25, Oxidized Bitumen 150/5, Oxidized Bitumen 95/25, Oxidized Bitumen 75/25

Oxidized Bitumen, applications:

Oxidized bitumen is used for insulation and production due to high temperature. For example,  Oxidized bitumen is mixed with gasoline and sprayed on concrete that has both penetration and dries quickly and the next step can be applied. It is very effective for the production of asphalt in places. One of the main uses of  Oxidized bitumen has been in covering pipes and producing paint. These items are widely used in the production of shingles and sealing  and bathroom floor coverings and insulation.
