What is Oxidized Bitumen
Oxidized Bitumen producing process
Oxidized bitumen is blown from blowing hot air to pure bitumen at the final stage of the purification operation In this process, hot air with a temperature of 200 to 300 degrees Celsius is blown through a perforated tube into a compartment containing bitumen.
As a result of this process, the hydrogen atoms in the bituminous hydrocarbon molecules are combined with air oxygen and the polymerization takes place with the formation of water
Oxidized bitumen penetration is lower than pure bitumen
It has a higher degree of softness and a lower sensitivity to temperature variations This type of bitumen is used to make roofing sheets, car tires and lining.
Oxidized bitumen Symbolic is R. For example R 80/25 bitumen means blown bitumen with degree of softness 80 centigrade and a degree of penetration is 25
Oxidized Bitumen uses
Oxidized Bitumen have different usages in different type industries so we will mention some of important applications of Oxidized Bitumen for you in this articles, Oxidized Bitumen in Gas and Oil industries would be using as coating materials for pipe lines and pipe joints of Oil And Gas Pipeline, lines, in electrical industries Oxidized Bitumen would be use as sealant of wire coating, blown bitumen is using in waterproofing industries too like building roofing felts in factories and first materials components who are producing waterproofing roofing felt sheets, Oxidized Bitumen is using in Bitumen and Asphalt factories for producing different grade of Bitumen and Asphalt for road paving at least one of the other usages of Oxidized Bitumen would be in sound dampen layer it is using as one of important materials for making Sound insulation layers.
