OXIDIZED BITUMEN 90/10

DESCRIPTION OF OXIDIZED BITUMEN 90/10

Oxidized Bitumen 90/10 is a type of bitumen that is produced by blowing air over pure bitumen. It is also known as blown asphalt 90/10 (blown bitumen 90/10). The penetration grade of oxidized bitumen 90-10 is significantly lower than that of conventional bitumen, and its softening point is significantly higher than that of conventional bitumen. The asphaltene that is found in this bitumen is capable of being polymerized by airflow, which results in the bitumen acquiring the quality of being stretchy.

This type of bitumen is referred to as Rubberized Bitumen, and the symbol R is used to indicate that it possesses characteristics similar to those of rubber. These numbers represent the point at which the substance begins to soften as well as the degree of penetration. For instance, oxidized bitumen R90/10 indicates that this particular bitumen has a softening point of 90 and a penetrability grade of 10.

We manufacture the highest quality Oxidized Bitumen 90/10 ( Blown Asphalt 90/10 ) in different types and export them from Iran and the UAE to other countries around the world.

OXIDIZED BITUMEN 90/10 PRODUCTION PROCESS:

In order to create oxidized bitumen 90/10, the BBU reactor at the refinery must first expose penetration-grade bitumen to hot air at a temperature that ranges anywhere from 240 to 270 degrees Celsius. Only then will the reactor be able to produce oxidised bitumen 90/10. Because of this, the refinery needs to maintain the temperature at a level that is constant and falls somewhere between 220 and 230 degrees Celsius. The reaction that takes place inside the reactor and involves the bitumen’s hydrogen atoms and the oxygen atoms of the air is induced by the heated air. The interaction of the bitumen with the air is what causes this reaction to take place.

The next thing that happens is that it starts to produce some steam, which, once it has been produced, needs to have the oxidation chamber emptied of it in order for it to continue operating properly. Once this steam has been produced, the next thing that happens is that it starts to produce some water vapor. Because of this, the presence of oxidized bitumen is brought about as a direct consequence of this.

APPLICATIONS OF OXIDIZED BITUMEN 90/10

Oxidized bitumen 90/10 can be used for a wide variety of purposes, some of which include the building of roads and the development of hydropower projects. It is also used for roofing, flooring, mastics, in the oil and gas industry, and in electrical applications.

Roads: Blown Bitumen 90/10 can be utilized for the construction of new roads, the paving of existing roads, and the performance of road maintenance. It is possible to incorporate it as an additive into asphalt, which can then be used for paving roads, highways, railroads, and parking lots. This can be done by following the instructions provided by the manufacturer.
Blown bitumen 90-10 is the material that must be used for the canal lining in hydro projects. These projects require its use. This particular variety of bitumen can be utilized in a wide variety of additional hydro projects, including the construction of embankments and dams, hydraulic structures, the protection of dam linings, and the stabilization of sand.
Roofing: Bitumen Oxidized 90/10 is used in the manufacturing of roofing felts, shingle roofs, damp-proof coating compositions, carriage roofing compounds, liquid roof coatings, and plastic cements. Additionally, it is utilized in the production of liquid roof coatings. In addition to that, it finds application in carriage roofing compounds. When it comes to waterproofing roofs, it is frequently the most effective method.
Flooring: One of the most common applications for blown asphalt 90-10 is the installation of flooring, which is also one of the most common uses. It is possible to use acid- and alkali-resistant bitumen mastic, which can be applied to the surfaces of facilities such as chemical plants, fertilizer plants, steel factories, and other types of facilities, to prevent corrosion. It is also possible for it to repair floors that have parquet on them.
Blown bitumen 90/10 is used frequently in the oil and gas industry as an additional layer of protection for pipelines against rust and corrosion.
Bitumen 90/10 is utilized in the construction of laminated boards for use in the electrical industry. In the field of electrical work, this adhesive is frequently used. It has the ability to fasten the covers of electrical connection boxes. In addition to being used in the production of wires and lithium-ion batteries, it is also put to use in the cable manufacturing industry.

Petro naft co. produces oxidized bitumen 90/10 ( blown asphalt 90/10 ) of the best quality in a variety of types and exports it from Iran and the United Arab Emirates to other nations worldwide.
