Definition Of Oxidized Bitumen 115/15
Oxidized bitumen 115/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. The most oxidized bitumen usable grade is bitumen 115/15 and 70% of our capacity is dedicated to this grade. bitumen 115/15 is a semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons and oxidized bitumen normally used for different purposes in the construction business. HJ OIL Co. has high softening point, high flash point and it is highly stable during melting.
HJ OIL Co. is a bituminous product manufactured by the special process of NON-OXIDATION but MODIFICATION of VACUUM BOTTOMS at 230 C temperature, resulting in a material of a much higher penetration index. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides SUPERIOR adhesive and waterproofing qualities when applied hot and allowed to cool than Oxidized Bitumen.
Applications Of Oxidized Bitumen 115/15
Oxidized bitumen 115/15 is using as raw material for bitumen coat, the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, ,crack seal and repairmen, civil works, construction industries; pavement, sealing and insulating buildings, insulation and isolation bitumen membrane sheet, adhesive, construction materials additive, dust-binding, coating, insulating and impregnating agent, make rubber and plastic products. bitumen 115/15 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, the base for synthetic turf; typical uses for bitumen 115/15 include roofing, pipe coating, hydraulic applications, Most bitumen 115/15 used to produce “mopping-grade” roofing asphalts. The special usage of oxidized bitumen 115/15 is bitumen paint manufacturing and oil well drill fluid. bitumen 115/15 is using in roofing manufacturing plants to produce shingles, roll goods, built-up roofing felts.
Oxidized bitumen 115/15 should be heated double temperature against the softening point to be able to have flow and viscosity. Normally bitumen 115/15 heating up to 230 ᵒc while it is the bale and if it is inside of bitumen bag needed the extra temperature to melt the bags and it is approx. 50 ᵒc more.
Before using Oxidized bitumen 115/15 surfaces must be dry, clean and free of loose particles, curing products, irregularities, and slurry. If you use this types of asphalt without cleaning the area Oxidized bitumen 115/15 will easily remove.
Storage & Handling Of Oxidized Bitumen 115/15
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 115/15
Oxidized bitumen 115/15 is available in bulk, drum, meltable and craft bag. This bitumen 115/15 are generally shipped as a solid and heated in a kettle at the worksite.
