Oxidized Bitumen Application
Oxidized Bitumen Application is very wide in some different industries. Bitumens 90/15, 10/20, 115/15, 120/15 which are produced by Vacuum Bottom oxidation in the presence of heat and blowing air into vacuum towers are called oxidized bitumen, blown bitumen which is a petroleum product is a high molecular weight hydrocarbon which includes oil, resin and asphaltene.
Blown oxidized bitumen: Blown bitumen is produced by blowing hot air into vacuum towers and is a petroleum product, a high molecular weight hydrocarbon which includes oil, resin and asphaltene. In the specifications of oxidized bitumen, the presence of 5 to 30 percent asphaltene in the bitumen causes the bitumen to become hard, and in blown bitumen or oxidized bitumen, due to the increase in the amount of asphaltene in its structure, the oxidized bitumen is harder and harder than ordinary bitumen.
In the analysis of oxidized bitumen R90.15, R120/15, R115/15, R10/20, the ASTM test (bitumen permeability degree), which is an international test, in different grades indicates the type of oxidized or blown bitumen. The abbreviation of oxidized blown bitumen is R, for example, if it is called R85.25 bitumen, it means that it is a blown bitumen with a penetration degree of 25 hundredths of a mm and a softening point of 85 degrees Celsius. Wherever the word R is in front of the bitumen specifications, it indicates that the bitumen is oxidized or blown.
Oxidized Bitumen application in industries
Due to their low penetration rate and high softening point, which makes them resistant to sunlight or high heat, and their suitable properties, oxidized bitumen application in some industries and for the production of moisture insulation, the production of rubber, the insulation of oil and water transmission pipes, the production of batteries, and the insulation of the floor and body of cars to prevent decay.
