Oxidized Bitumen 115/15
Oxidized Bitumen 115/15 made by air Blowing Process. Heated Bitumen penetration under controlled environment is blown with air which controls oil content in bitumen while it oxsied. Different grades for suited uses produced. Grades designated by two numbers to indicate mid-points of softening point. Also their penetration ranges.Blown Asphalt 115/15:
Blown Asphalt 115/15 is produced by either continuous or Staggered Blowing Process.
Heated Penetration Grade bitumen under controlled environment is blown with air which controls the oil content in the bitumen while it oxidized.
The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.
Blown Asphalt 115/15 is bitumen obtained from crude oil refining and then subjected to an oxidation process with a catalyst by using hot air blow. It is used in hot mix supply solution using several layers of product, but its main purpose and objective is for industrial applications such as roof felts, waterproofing, roof an floors anti-rust pipe coating, anti-slip layer compound, sound dampening felts, coats for automobile industry, joint filling compounds, sealants, bituminous mastic and many more.
Blown Asphalt 115/15 is 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.
Blown asphalt 115/15 is air blown asphalt and produced by several methods by high temperature and pressure.
Chemical Mine World has high tech system that changes down the risk of high pressure and temperature and blowning the asphalt in very short time and by this patent increase asphaltene content quickly by adding additive into asphalt emulsion system under ultrasonic. This type of blown asphalt 115/15 has various usages including gel type asphalt for encapsulation of hazardous material and the metal surface.
Blown asphalt 115/15 is containing:
1. Saturates
2. Aromatic
3. Resin
4. Asphalten'es
Chemical Mine World is one of the market leaders in Production, Exports, and brokerage different grades of Blown Asphalt with excellent quality. Our sales team is committed who understands your requirements due to many years of experience in supplying the bitumen products. If you are more interested in product information or need to place an order contact or inquire our Sales team.
Application of Oxidized Bitumen 115/15:
The Oxidised Bitumens should be heated double temprature against the softening point, and this is because of ablility to have flow and viscosity.
- Dam proof
- Canal sealer
- Tennis court
- Stockyard
- Treatment and road beds
- Leaching blown asphalt 115/15 could be classified into so.
Therefore gel and gel types by traditional theology index such as complex flow, asphalt aging index, plastic flow, penetration index, ductility at 25C and correlation of asphaltene aromaticity with H/C ratio. It used on paving, roofing and metal coating.
Oxidized Bitumen 115-15 uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement ,crack seal and repairmen, civil works, roofing, construction industries and also sealing and insulating buildings, adhesive, construction materials additive, dust-binding, coating, insulating and impregnating agent, make rubber and plastic products. The oxidized bitumen 115-15 products are for paving, roofing.
In addition it uses in asphalt based paints for corrosion protection of metals. Also in lining public works structures, adhesives, electrical laminates, base for synthetic turf. Furthermore typical uses for oxidized bitumen 115/15 include roofing, pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing.
Storage & Handling:
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 Chemical mine World modified 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
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
For Health and Safety information, please make reference to the relevant MSDS.
Health & Safety of Blown Asphalt 115/15:
Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline. Care should be taken when heating Blown Asphalt 115/15 to avoid over heating
Packing of blown asphalt 115/15:
The Chemical Mine World is manufacturer of blown asphalt 115/15 in various packing including kraft bag, meltable plastic bag, drum and bulk blown asphalt 115/15 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached.
The Chemical Mine World blown asphalt 115/15 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The blown asphalt grade 115/15 means softening point is 115°c and penetration is 15 desimillimiter is produced in compliance and conformity to ASTM standard and meets the following specification.
