Definition Of Oxidized Bitumen 105/35
Oxidized Bitumen105/35 is a good grade of oxidized asphalt to use as bonding compounds as hot melt adhesive at an application rate of approximately 1 Kg/m3 to bond the preformed sheets together and to structure which is made by Oxidized Bitumen 60/70 by hot air. Blown bitumen 105/35 is a semi-solid oxidized grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business.
Applications Of Oxidized Bitumen 105/35
Oxidized bitumen 105/35 uses in the chemical, fuel, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement ,paint, crack seal and repairmen, civil works, roofing, construction business ; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The bitumen 105/35 products are for paving. 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 105/35 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing. Blown bitumen 105/35 is using insulation and isolation bitumen membrane sheet. Car undercoating Automobile industry is specially required for blown bitumen. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating.
Blown Asphalt 105/35 should be heated double temperature against the softening point to be able to have flow and viscosity. To use blown bitumen 105/35, surfaces must be dry, clean and free of loose particles, formwork, curing products, irregularities, slurry, etc.
Storage & Handling Of Oxidized Bitumen 105/35
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 105/35
Oxidized bitumen 105/35 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.
