Definition Of Oxidized Bitumen 150/5
Oxidized bitumen 150/5 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. This type of bitumen is hard and breakable. Oxidized bitumen 150/5 is the semi-solid oxidized grade of petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction industries. Bitumen 150/5 should be heated double temperature (200ᵒ-300ᵒC) against the softening point to be able to have flow and viscosity. Normally heating of such hard oxidized bitumen should be arranged via hot oil by circulation inside of the isolated jacket.
Oxidized Bitumen 150/5 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. HJ OIL Co. can be supplied in any grade.
The oxidized bitumen 150/5 means the softening point is 150 ° c and penetration is 15 desi millimeter.
During the loading period, HJ OIL Co. guarantees the quality and quantity of 150/5 through the inspection of international inspectors, and controls the production through QC through the batch test report before shipment, and conforms to ASTM standard specifications.
Applications Of Oxidized Bitumen 150/5
Oxidized bitumen 150/5 uses in the chemical, raw material for bitumen coat, lacquers, varnishes, paper-pulp-board, textile processing, pavement, crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products. bitumen 150/5 products are for paving, roofing; also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf; typical uses for bitumen 150/5 include roofing, pipe coating, hydraulic applications, 150/5 is mainly using in paint manufacturing and coating in hot area.
Before using bitumen 150/5 surfaces must be dry, clean and free of loose particles, curing products, irregularities, and slurry. If you use this types of bitumen without cleaning the area the bitumen 150/5 will easily remove.
Storage & Handling Of Oxidized Bitumen 150/5
Heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.
However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.
Note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.
The Oxidized Bitumen material should be broken up prior to placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flash point of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.
Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.
Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.
Packing Of Oxidized Bitumen 150/5
Oxidized bitumen 150/5 is available in 25 kg meltable and craft bag, drum, and bulk. Normally oxidized bitumen packing on the pallet and 40 bags can stack on the pallet. 20 pallet can load to the 20ft container.
