Description of Oxidized Bitumen 150/5
A Continuous Blowing or Staggered Blowing Process is used to produce Oxidized Bitumen 150/5. The oil content in the bitumen while it’s oxidizing is controlled by blowing air within a controlled environment while Penetration Grade Bitumen is heated. A two-number scale is used to indicate the mid-point between the softening point and penetration range of the grades for suited applications.
Blowing Bitumen 60/70 by hot air produces Asphalt 150/5 by using Petroleum Bitumen. The Bitumen 150/5 is produced in compliance with the ASTM standard for penetration of 15 desi millimeters and a softening point of 150°c. This type of bitumen is hard and fragile.
Additionally, heated hard bitumen oxide should be circulating inside the jacket via hot oil. Bitumen 150/5 in any grade can also be obtained from us.
Water resistance, flexibility, and durability are some of the best characteristics of oxidized bitumen. The chemical stability of the compound is excellent. In addition to being completely waterproof, oxidized bitumen also has a very flexible and chemically stable composition. Oxidized bitumen is also a very sought after compound in numerous applications because of its very notable technical advantages.
Uses of Oxidized Bitumen 150/5
A typical application for oxidized bitumen 150/5 includes anti-slip layer compound for pilings, roof felts, sound dampening felts, under carriage sealant, cable joint protection, joint filling compound, sealant compound, and other applications.
Isolation bitumen membrane sheet is made with this material for use in roof coating, roofing insulation, and as a raw material in bitumen coat. The oxide product is also useful in the processing of chemicals, fuels, paints, lacquers, varnishes, paper pulp and board, and textiles. Construction includes road construction, pavement repair, crack sealing, civil works, and roofing. Moreover, it is used for sealing and insulating buildings, adhesive, construction materials additive, dust-binding, coating. With a wide range of applications in the insulation and impregnation processes, rubber and plastic products can be produced.
Roofing and paving are the applications of Bitumen 150/5. Used as an inlining material in public works structures, an adhesive in electrical lamination, a base for synthetic turf, and as corrosion protection in asphalt-based paints for metals. A typical application for Oxidized Bitumen 150/5 includes roofing, pipe coating, Portland cement pavement, hydraulics, and paint manufacturing.
Technical Advantages of Oxidized Bitumen 150/5
- Durability
- Flexibility
- Water Resistant
- Chemical Stability
Compared to paving grade bitumen:
- Reduced temperature susceptibility
- Exhibits a more ‘solid’ nature at ambient temperatures
- High penetration index
Packing of blown asphalt 150/5
Blown asphalt 150/5 is available in various packing, including kraft bags, meltable plastic bags, drums, as well as bulk blown asphalt 150/5 which is formed by hot air blasting until the desired specifications are achieved. Depending on the grade and penetration range, the oxidized bitumen 150/5 can be provided in any grade. Optimum strength desi millimeter grade 150/5 is produced in compliance with ASTM standard and meets the following specifications. It has a melting point of 150°c and penetration of 15 desi millimeter.
Storage & Handling
Heating packaged bitumen is a critical phase in many applications. A boiler situated on site is usually used to melt packaged materials. Nevertheless, control of the heating phase is imperative for the safety of the product as well as its quality.
It is crucial to control the heating phase of bitumen, since it is a poor heat conductor.
Oxidized Bitumen material should be broken up before being placed in the boiler. As a result, a larger surface area is exposed to the heat and a more even heating process is achieved. As a result of the smaller exposed area, excessive heating at the base and sides of the boiler may result in localized overheating, altering the properties of the modified bitumen and potentially producing low lash vapors due to thermal cracking of the bitumen. This low flash vapor volume determines the fire risk and thus the flash point of the oxidized bitumen becomes irrelevant. Melted bitumen should not be left in a boiler and reheated from cold because a pressurized pocket of low flash vapor is likely to develop if convection is reduced (lack of convection means poor heat transfer). Monitor or control devices for temperature should be placed in a logical location. Since bitumen has a poor thermal conductivity, a thermometer located some distance from the heat source could read a hotter temperature (even hundreds of degrees) than the temperature near the heat source. Refer to the relevant MSDS for more information on Health and Safety.
