Oxidized bitumen 105/15

oxidized bitumen 105/15 specifications:

bitumen 105/15 is produced as a result of vacuum bottom oxidation in the presence of heat and blowing air into the vacuum towers, is called oxidized bitumen, blown bitumen, which is a petroleum product, is a hydrocarbon. It has a high molecular weight, which includes oil, resin and asphalt .
In the characteristics of oxidized bitumen, the presence of 5 to 30% asphalt in the bitumen makes the bitumen hard, and in blown bitumen or oxidized bitumen, due to the increase in the amount of asphalt in its structure, the blown oxidized bitumen is harder than normal bitumen. be more
In the analysis of oxidized bitumen R105/15 , the ASTM test (bitumen permeability degree), which is an international test, indicates the type of bitumen oxidized or blown in different grades.
The abbreviation of blown oxidized bitumen is R, for example, if bitumen is called R105.15, it means that it is blown bitumen with a penetration degree of 15 hundredths of a millimeter and a softening point of 105 degrees Celsius, wherever the word R is in front of the bitumen specifications, it indicates that the bitumen is oxidized or blown. is.
This type of bitumen, which is the result of the oxidation of penetrating bitumen exposed to very hot air, is completely hard at ambient temperature and requires a lot of heating to use it.

Oxidized bitumen 105/15 applications:

Oxidized bitumen 105/15 in chemicals, fuel, paint, varnish, alcohol varnish, paper pulp, textile processing, road construction, paving, repair work, civil works, roofing, construction industry, sealing and insulation of buildings, glue, Construction additives, dust binders, under the title of coating, insulation and saturating materials, are used in the production of rubber and plastic products. It is also used in asphalt-based paints to protect against metal corrosion, in the lining of public structures, as an adhesive in electric sheets and artificial grass bases. Common uses for blown asphalt 105/15 include roofing, pipe lining, Portland cement paving, hydraulic applications, and paint production.
These Oxidized bitumen blocks are environmental friendly and safe to handle. Some advantage of these bitumen packing are Water proof packaging and meltable naylon bags can be melted in conventional boilers without to need for removal available as palatalized and non-palatalized.

Oxidized Bitumen 105/15 packing :

Oxidized Bitumen 105/15 packing would be very important and must have these properties:
Packing must be heat resistant when are filling in the factory

Bags weight must be 25 kg for better handling and use in the production lines of factories
Oxidized bitumen 105/15 must separate from bags very easily and clearly
The bags must fill in one poly amid bag when oxidized bitumen is hot and when it became cold in the water pool put in 25 kg PP bags for avoiding leakage in containers.

One of the important items is that the inner packing of oxidized bitumen must be Polyamide bags because it can melt inside the mixers of waterproof membrane factories and asphalt factories also it will help them to use it directly in the production line without wasting time, and energy and extra charges fee for separating the polyamide bags from Oxidized Bitumen 105/15, Polyamide would be an example of semi-crystalline polymers in which the amide group is placed in the form of a polymer chain Also, due to having hydrogen bonds, they have extraordinary strength. Polyamide is meltable and melts at a temperature of 90 degrees Celsius.
Also, this polyamide is a very suitable option for packing types of oxidized bitumen due to its high resistance to petroleum solvents, high abrasion, and impact resistance against successive bending.
