Bitumen (Latin bitumen - mountain resin)- a substance that is a solidified or viscous mixture of hydrocarbons and their derivatives, a kind of mix. This product is insoluble in water, complete or partial dissolution is possible with solvents such as benzene, chloroform, ethyl alcohol, acetone, turpentine and others, the density of which is from 0.95 to 1.5 g / cu. cm.

The properties of bitumen are influenced by:

bitumen production method
raw material quality
production parameters

The production of high-class bitumen is influenced by the component composition of oil, the sequence of the general technological scheme of production.

Stamps

There are differences in the areas of application of roofing bitumen:

BNK-40/180– roofing bitumen used for impregnation;
BNK-45/190- roofing bitumen, used for impregnation and formation of the cover layer;
BNK-90/30- roofing bitumen, used only for the cover layer.

The production of high-class construction bitumen is influenced by the components that make up the oil and the sequence of the production process.

Technical requirements

To comply with the regulations in the production of bitumen, it is necessary to comply with standard technical requirements:

Rationing for the BNK-40/180 brand:

Rationing for the BNK-45/190 brand:

softening temperature - 40 - 50 ° C.
needle penetration depth at 25°C - 160 -220 mm.
discrepancy after heating the mass - 0.80%.
flash point - 240°C.
mass fraction of water - traces.
mass fraction of paraffin - 5.0%

Rationing for the BNK-90/30 brand:

softening temperature - 70 - 95 ° C.
needle penetration depth at 25°C - 25 - 35 mm.
brittleness temperature – -10°C.
solubility with organic solvents - 99.5%.
discrepancy after heating the mass - 0.50%.
flash point - 240°C.

Test Methods

The generally accepted test methods for oil roofing bitumen include the following physical and chemical indicators:

penetration;
softening;
fragility;
discrepancy after heating the mass;
penetration from the original;
flash point;
paraffin content.

Sampling from each batch of bitumen in the amount of 0.5 kilograms is carried out according to.

Acceptance rules

After the whole party roofing oil bitumen will be prepared for shipment, a quality certificate is issued for it. Only one quality certificate is issued for each batch. A batch can be recognized as a different amount of bitumen, homogeneous in terms of quality.

Getting unsatisfactory results testing on one or more indicators leads to repeated tests, but the sample volume must be doubled. The conclusion of repeated test results is valid for the entire batch.

The manufacturer is checking for the presence of water (mass fraction) at least once every six months. Once every three months, the solubility and the proportion of paraffin (mass) are determined.

Packaging, labelling, transport and storage

For delivery with subsequent storage in warehouses or for bitumen objects under construction, there is a packaging container that serves as protection against dust and dirt, ensures the compactness of the cargo on vehicles.

Basic packaging methods apply such as clovertainers, euro barrels (metal), big bags and craft bags. Bitumen carriers are used to transport bitumen in a state ready for use.

clovertainer has the shape of a cube. The pallet and cover are made of plywood, the walls are made of corrugated cardboard. Unpacking takes a couple of minutes with a grinder.
metal euro barrel easy to use because the lid has a metal clamp. There is no need to unpack, just open the barrel, heat the bitumen, pour the right amount and close it again. Safety of quality is provided at the expense of a cover with a collar.
big run- the packaging is a universal polypropylene bag, which can take the form of the container, which is designed for unloading by loading mechanisms.
kraft bags- the most impractical container, both during transportation and when opening the package.
bitumen carrier– tank truck with double walls and wall heating. Due to heating, bitumen does not need long-term heating at facilities under construction.

To determine whether what type of material, its characteristics, characteristics storage and transportation, volume or weight, batch number and certification (if any) there is a marking, information that is applied to each commodity unit.

For oil roofing bitumen - this is BNC, numbers 40/180; 45/190; 90/30 in the numerator is the temperature at which the bitumen becomes soft, and in the denominator is the expected temperature of the solid state.

Ensuring the safety of bitumen oil in containers is produced using racks or pallets. When stored in stacks in closed warehouses, under sheds or on planned industrial sites with concrete or asphalt pavements, which ensures their protection from exposure to sunlight and precipitation.

In cases of bitumen transportation in the solid state, transportation is carried out on specially equipped collapsible forms. Transportation of products from hydrocarbons requires the provision of all necessary requirements fire safety due to self-ignition. Compliance with elementary safety rules eliminates the possibility of accidents and emergencies.

For roofing mastic belong to the fourth class of danger. This class represents low-hazard combustible substances. For them, the flash point is not lower than 240 degrees Celsius. Self-ignition is possible at a temperature of 300 degrees Celsius. - ;

eye protection – .

Bitumen that has fallen on the worker's body must be cooled with running water. Using petroleum jelly or any softening cream, carefully remove bitumen particles from the damaged area of the body. It is necessary to provide first aid for victims of thermal burns.

The workplace for work with bitumen must be equipped with ventilation equipment.

In the event of a fire, it is necessary to localize the source of the fire with a foam jet. Small fires are localized with an ORP fire extinguisher, sand or felt mat.

Bitumens have found application in a wide range of industries - in the rubber and cable industries, in the production of varnishes, waterproofing and paints. They are also very commonly used in the construction industry.

Oil roofing bitumen is one of the most popular materials used in the production of various roof structures.

They are produced by heat treatment oil fractions. The main parameters that affect the final product obtained from oil are the various properties of thermal effects on the raw material itself (pressure, temperature and duration of distillation), the quality of the original oil feedstock.

Due to the fact that prices for roofing bitumen are low, the demand for them is very high.

Characteristics and features

The main characteristics that roofing bitumen must have are spelled out in GOST-10923 - 93, which lists the acceptance rules, characteristics, and a calculation table for determining the bitumen penetration index. It also lists brands:

BNK-90/30 - is obtained as a result of the oxidation of bitumen BNK 45/190 and is used for the cover layer. Possesses low coefficient of penetration, high softening point;
BNK-40/180 - is produced during the oil oxidation reaction and is used for impregnation. Has an average coefficient of penetration, low softening point;
BNK-45/190 is the result of the oxidation reaction of finished raw materials. It is used as an impregnation, as well as to obtain a hard casing bitumen. Its properties are high penetration coefficient, medium softening point.

Types of roofing bitumen

Roofing bitumen is used in the production of many types of roofing materials. The price of these materials allows them to be used in a wide range of construction projects. Consider the most popular types in more detail:

Ruberoid is a waterproofing material for roofing, which was made of cardboard impregnated with bituminous resins and coated on both sides with bitumen and additives. These additives come in three types: pulverized, fine-grained and coarse-grained. Supplied mostly in rolls.
Bituminous tiles - similar in composition to roofing material, but differ from it in surface - the top is covered with stone chips, and the bottom is made self-adhesive. Supplied in sheets that can be given a variety of textures, colors and shapes.
Roofing bituminous tape - mainly used for renovation various types roofs. Its composition differs from other types - the outer layer consists of aluminum, the inner layer consists of bitumen with additives, the last layer is a polyethylene film. Can be supplied in rolls.

Petroleum roofing bitumens in this case are made in such a way that they have good adhesion with the most various materials- with metal, polymers, stone.

You can buy roofing bitumen of all types at ExportNeft. We offer a wide range and guarantee the high quality of all products.

Modern trends in construction tend to improve the manufacturability of all stages and, as a result, to accelerate all construction processes. These conditions correspond to a relatively new type of roofing material - a membrane based on bitumen. The main difference from other types of analogues: the roof is covered with a single waterproofing elastic sheet, which excludes the treatment of open fire.

Buying roofing bitumen at ExportNeft means getting a quality material that has all the necessary certificates at an attractive price.

Purpose

It is applied during construction, road-building and roofing works.

The TransGazRemont company sells various types of building materials for repair and installation work. We carry out deliveries of oil bitumen (BNK 45/180). We also deliver other viscoplastic, solid and liquid petroleum products.

According to the chemical composition, bituminous mixtures belong to high-molecular hydrocarbons and their non-metallic derivatives of oxygen, nitrogen, and sulfur. The materials are completely soluble in carbon disulfide. To study the compositions, they are divided into the main groups of hydrocarbons (similar in properties) - resins, oils, asphaltogenic acids, asphaltenes and their anhydrides.

The most important characteristics of NBR 45/180 or 190 are ductility, toughness, brittleness and softening temperature. It should also be noted their excellent adhesion, the material is able to combine mineral grains of fillers into a monolith. Petroleum bitumens impart hydrophobic properties to structures.

The main feature of NBR 45/180 or 190 is the viscosity, which depends on the group composition and temperature. It indicates the resistance of the inner layers of bitumen when moving relative to each other.

Grades BNK 45/180 or 190

Depending on the main characteristics, plasticity, viscosity, softening point, petroleum bitumen is divided into grades:

for road construction. According to GOST, there are 5 grades - from the oil road composition 200/300 to 40/60, where the digital designation indicates the limits of penetration change at + 25 ° C that are permissible for this composition. This also includes four types of BN from 200/300 to 60/90;
for construction work. According to GOST, there are three grades, they are designated BN and are 50/50, 70/30, 90/10. The upper value of the fraction indicates the softening point, and the denominator indicates the penetration rate at + 25°C;
for roofing. In accordance with GOST, there are such grades of bitumen: BNK 45/180 or 190, as well as 90/40, 90/30. The numerator indicates the average melting point and the denominator indicates the penetration value at + 25°C.

In addition to viscoplastic and solid bituminous compounds, there are liquid ones. They have low viscosity at room temperature and are used cold or slightly warm.

Bituminous binders. Petroleum bitumen

Bituminous binders are complex mixtures of high-molecular hydrocarbons and their non-metallic derivatives (compounds of hydrocarbons with sulfur, oxygen, nitrogen). Distinguish natural and artificial oil bitumen. Natural bitumen is extracted from asphalt rocks organic solvents or boil them in hot water. Artificial bitumens are residues obtained from oil refining. At normal temperatures, bitumen occurs in both solid and viscous-liquid states. When heated, they soften (liquefy), and when cooled, they return to their original state again. Possessing an amorphous structure, bitumens, unlike crystalline bodies, do not have a specific melting point. There is a certain temperature range of softening, i.e., a gradual transition from a solid state to a viscous liquid.

Bitumens are hydrophobic (not wetted by water), waterproof, have a dense structure, their porosity is almost zero, so they are waterproof and frost-resistant. These properties allow bitumen to be widely used for roofing and waterproofing. Bitumens are resistant to aqueous solutions of many acids, alkalis, salts and most aggressive gases, but dissolve partially or completely in various organic solvents (chloroform, ethyl alcohol, gasoline, benzene, xylene, turpentine, acetone, etc.). Therefore, they can be used to prepare some mastics, varnishes and paints. Molten bitumen retains some ductility upon cooling and becomes brittle only at a relatively low temperature.

To improve the properties of bituminous binders, they are fused with rubber; the resulting materials are called rubber-bitumen; polymers are added, after which they are called bitumen-polymer. According to the purpose, bitumen is divided into construction, roofing and road bitumen.

Construction oil bitumen(GOST 6617-76 *) are used for construction work in various sectors of the national economy. They are obtained by oxidation of the residual products of the direct distillation of oil and their mixtures with asphalts and oil production extracts.

We offer roofing bitumen BNK 45/180. The number 45 in the index indicates that the softening of the bitumen begins to occur at a temperature of +45 o C. The number 180 is the penetration rate. Given these indicators, we can say that this bitumen - the best option for use as an impregnation.

The popularity of this material in construction, repair and other types of work is due to the following factors:

relatively low cost of the material itself, as well as the performance of work using it;
roofing bitumen 45/180 is characterized by absolute moisture impermeability. Due to this, when using it, it is possible to provide reliable protection of buildings and structures from the harmful effects of moisture on them.
the porosity of the material is almost zero. In addition to water resistance, this affects such an indicator as the frost resistance of bitumen.

Working with BNK 45/180 bitumen

To ensure high-quality waterproofing when using this material, it is necessary to pre-prepare the surface to be treated. If necessary, exfoliated areas must be chiselled to a hard layer. Gating points, as well as areas where there are too deep recesses, must be leveled using special tools.

After that, the surface is cleaned from a variety of debris, mastics and special tools. Then the bitumen is applied in the chosen way.

If you are interested in the price of bitumen BNK 45/180, please contact the managers of our company. We work with any volume of this material. Deliveries are organized as soon as possible.

Oil bitumen is a solid, viscoplastic or liquid product of oil refining. The chemical composition of bitumens indicates that they are complex mixtures of high-molecular hydrocarbons and their non-metallic derivatives, such as nitrogen, oxygen and sulfur, which are completely soluble in carbon disulfide.

Where is natural bitumen mined?

The procedure for obtaining and complex transformation of natural bitumen is carried out in the following order:

mining of bituminous rocks
separation of organic and mineral parts from bituminous rock
bitumen transportation
stages of bitumen processing.

Based on the location conditions and physical characteristics of raw materials, the process of developing natural bitumen deposits is carried out by the following methods:

quarry and mine cleaning method involves the extraction of rock to the surface with further extraction of bitumen using a solvent or hot water with the addition of emulsifying components
mine drainage method involves the extraction of natural bitumen in a mine by gravity through a system of ascending drainage wells drilled from mine workings
the borehole in situ method is distinguished by the extraction of natural bitumen by means of thermal or other action on bituminous rocks through wells drilled from the surface.

Mine (quarry and mine) methods are suitable for the development of deposits with a bitumen saturation of host rocks of more than 10% and a depth of 60-90 meters. The share of bitumen production in this case is about 85 - 90%. This is how bitumen is mined at the Yaregskoye oil field in the Komi Republic.
Borehole methods are suitable for the development of deposits of liquid natural bitumen, for example, bituminous oil. The depth of occurrence of such deposits exceeds 100 meters. This method makes it possible to achieve an oil recovery factor of only 30%.
Various natural bitumens are not yet a marketable product, like oil or gas. To get a commercial product, you need to carry out additional technological processes.
Petroleum bitumen can be obtained at the refinery from various kinds oils that have different chemical composition. At the refinery, oil is distilled with the separation of fractions:

light products - gasoline, naphtha, kerosene
lubricating oils
other types of petroleum products.

Residual products at the end of the selection of fractions lighter in mass - tar, cracking - are then used as raw materials for the production of oil bitumens of certain parameters. Today, there are such methods for obtaining oil bitumen:

atmospheric-vacuum distillation of oil to obtain residual bitumen, which have a low viscosity and are most often oxidized
oxidation of oil residues to obtain oxidized bitumen. Such products have a higher viscosity
mixing residues formed during the distillation of oil to obtain compounded bitumen. They are produced by mixing deasphalting bitumen (the end product of processing tar with liquid propane) with oil distillates.

Oil construction bitumen

Construction bitumen happens:

for public works. There are three grades of oil bitumen in this category: BN-50/50; BN-70/30 and BN-90/10, where the numerator is the softening temperature coefficient, and the denominator is the average indicator of the penetration change limits
for roofing works, grades BNK45/180; BNK-90/40 and 90/30, as well as BNK-45/190
BNI - oil insulating - grades BNI-IV-3, BNI-IV and BNI-V. Such bitumens are used in the process of insulating underground pipelines to protect them from corrosion.

In addition to the listed brands, there is also liquid road bitumen. It has a low viscosity index and is used in road construction as part of asphalt concrete, if it needs to be laid at low air temperatures. Liquid bitumen is produced by mixing viscous BND bitumen with distillate thinner fractions that slowly evaporate after the paving is laid. However, due to the high fire hazard and the enormous harm to nature, it is used quite rarely.

bitumen properties

The main properties of bitumen include:

viscosity
plastic
softening and brittleness temperature
adhesion.

The most important characteristic of the structural and mechanical properties of bitumen is the viscosity, which depends on temperature and group composition. Viscosity characterizes the resistance of the inner layers of bitumen to movement relative to each other. Many bitumens exhibit inconsistent and decreasing viscosity with increasing shear stress or strain rate gradient. As the temperature rises, the viscosity decreases, and as it decreases, on the contrary, it instantly increases. In conditions of minus values, bitumen has increased brittleness. To measure the viscosity, a method such as penetration of a needle into the bitumen (penetration) and depth measurement is used. The depth of entry of the needle into the bitumen is determined on a device - a penetrometer. To do this, a load weighing 100 g acts on the needle for 5 s at a temperature of 25 ° C or 0 ° C. The penetration of solid or viscous bitumen is determined in units (degrees) equal to 0.1 mm of penetration of the needle into the bitumen. More viscous types of bitumen have a lower penetration rate.
Plasticity is also an important characteristic of bitumen. The plasticity index increases with an increase in the level of oils, the duration of the load, and an increase in temperature. For example, with an increase in the amount of resins and asphaltenes, plasticity at a constant temperature increases.
The softening temperature is determined on the device "ring and ball" ("K and W"). The softening temperature of bitumen, measured in degrees Celsius, is equal to the temperature of the water bath in the glass of the device, while bitumen, located in a brass ring with a diameter of 16.0 mm, changes under the influence of a metal ball weighing 3.5 g and smooth heating of the liquid at a speed of 5 ° C per minute touches the bottom shelf of the stand. The softening temperature of viscous and hard bitumens ranges from 20 to 95°C.
An interesting feature of bitumen is high adhesion, that is, sticking to the surface of various mineral and organic compounds.

Grades of oil bitumen

According to various indicators of the main properties, especially viscosity, plasticity and softening point, all petroleum bitumen is divided into grades:

for road construction, GOST provides for five grades from BND (road oil bitumen) -200/300 to BND-40/60. Numerical indicators reflect the limits of change in penetration coefficients at 25 ° C, acceptable for a particular brand, and four BN grades from 200/300 to BN-60/90
for construction work, GOST provides for three grades, which are designated "BN" - oil bitumen: BN-50/50, BN-70/30 and BN-90/10. In this case, the numerator of the fraction reflects the softening temperature according to "K and W" (ring and ball), and the denominator is the average value of the change in penetration at 25 ° C
for roofing work, GOST provides for the following grades: BNK (roofing oil bitumen) -45/180, BNK-90/40 and 90/30, as well as BNK-45/190. Here, the numerator of the fraction reflects the average value of the softening point indicators for "K and W", and the denominator - the average value of the penetration indicators by 25C.

Roofing oil bitumen

Viscous oil bitumen is indispensable in providing waterproofing of buildings. Low price and 100% moisture impermeability have long made bitumen very popular in the construction of residential, household, industrial and other buildings.
All types of roofing bitumen are characterized by a high self-ignition temperature, which is more than 300 degrees, and a flash point of at least 240 degrees. Roofing bitumens are used in the process of impregnation of roofing materials, as well as an independent material for roof waterproofing.
Among the roofing materials in the production of which bitumen was used, include:

bituminous paper
ruberoid
rubemast
glassine
rubiteks and others.

For impregnation, bitumen of the following grades is used: BNK 45/90 and BNK 45/180. The covering material is BNK 90/30 or BNK 90/40 bitumen.
It should be noted that all bitumens are hydrophobic, they do not allow moisture to pass through and are not wetted by water. There are no pores in the structure of bitumen, so they are waterproof. Roofing bitumens are not afraid of aqueous solutions of aggressive substances, for example, salts, most alkalis or acids. However, organic solvents (benzene, acetone, turpentine, gasoline) have a negative effect on bitumen.
Roofing bitumens are frost-resistant, which is why they are so in demand in construction work. If special substances are added to bitumen, then a material is obtained that does not require heating for application to the surface. Such material is called bituminous mastic. You need to work with it in the same way as with coating waterproofing.
