What is Bitumen?Oil; It is the general name given to hydrocarbons in gas, liquid and solid form. Liquid hydrocarbons are called crude oil, gaseous ones are called natural gas,asiagilsonite and solid ones are called asphalt-paraffin or bitumen according to their composition.By separating the crude oil extracted from the well into its components after distillation, asphalt, paraffin, gasoline, etc. obtained. After this process, bitumen, which is too solid to be used at normal air temperature; It is diluted with gasoline, diesel oil, kerosene and water, which is a different technique,asiagilsonite and made to be used. At this final stage, asphalt is now ready to be used in floor coverings.
Bituminous hot mixes are obtained by heating the asphalt binder and aggregate to the appropriate temperature and mixing them in the plant in appropriate proportions and are used in the upper layers of high standard flexible coatings.

The bitumen we sell has international quality and certification.Bitumen is black in color and in paste form. It is an oil derivative.asiagilsonite Unusual bitumen is available.
It is obtained in two stages of crude oil distillation, this process is usually done in oil refineries
Bitumen production stages;First, lighter materials such as propane and gasoline are separated from the crude oil. This step is performed at a pressure of atmospheric pressure.Second stepAt this point, materials heavier than crude oil are removed, such as kerosene and diesel.The second step is performed at a pressure close to vacuum.At the end there is a mixture of very fine solids soaked in a substance called malton that looks like oil.
Bitumen;Bitumen occurs naturally in nature.asiagilsonite The long time pass is achieved by the gradual conversion of crude oil and the evaporation of its volatile substances called natural bitumen.
It can be more durable and pure in nature(Bitumen lake) like bitumen lake Behbahan Iran and bitumen lake Tyrinidad America, or get it out of the mines and sayNatural bitumen obtained from petroleum or special minerals is called pure bitumen.Another name is Gilsonite bitumen, a natural resin hydrocarbonIt is like a concentrated oilGilsonite is a shiny black bulk material and is brittle, similar to glass minerals.It is very easy to transform a dark brown powder. Discovered in the 1860sHowever, it wasn't until 1880 that Samuel H. Gillson used it as a sealant for lumber and insulated cable and solvent oil. was not well knownGilsonite's unique feature is its high nitrogen content.
Bitumen application and use;Gilsonite is soluble in aromatic oils and oil solvents such as bitumen.They are often used to loosen and tighten due to their excellent compatibility with petroleum products.For the use of Gilsonite on asphalt, the amount of ash in it is not important.Ash is not a nuisance factor in GilsoniteThis feature is used for better mixing of asphalt with other additives.Some experiments have shown. The presence of sulfur compounds in Gilsonite during concrete pouring increases asphalt resistanceThe presence of sulfur in Gilsonite is an important factor in mixing with asphalt, so Gilsonite is well suited for mixing with asphalt.Building materials, paint, resin, asphalt, road paving, casting, chemicals, mud and cement, drilling and rubber bitumen or geylonite applications
The most important bitumen applications are in Isogam and asphalt production;One of the outstanding properties of Gilsonate materials is their solubility in non-polar solvents such as carbon disulfide, toluene as well as molten bitumen.This property of Gilsonite is used in isogam production and moisture insulation industry.Gilsonite is highly hydrophobic and acid resistant, often used in the production of asphalt and isogamGilsonite is a suitable modifier for bitumen refineries, especially for asphalt and isogamous due to its polymeric hydrocarbon materials.Gilsonite reduces penetration, increases visغير مجاز مي باشدity, increases softness and increases thermal resistance of bitumenSulfur and sulfur compounds in Gilsonite also increase the strength and power of asphalt. One of the main applications of Gilsonite
Provide color and ink;Black and brown pigments are extracted from bitumenThese pigments are used in the production of printer inks.
Black carbon is widely used to produce gilsonite resin black ink and viscous ink in IranA special type of Gilsonite is also used to make asphalt black paints and lacquer oils.
Use as cover;It is used for coating exterior surfaces. It is also used to make surfaces resistant to acid, vehicle chassis coatings, steel structure coatings.Used as a low-غير مجاز مي باشدt alternative to other resins in black ink compounds
Insulation;Bitumen is widely used in the insulation of dams, bridges and canals.Preparation of emulsion bitumen;Gilsonite micronized powder is used in the preparation of aqueous emulsion bitumenEmulsion bitumen is mainly exported. Emulsion bitumen is known as green and environmentally friendly bitumen.
Coke production;Gilsonite contains 80-70% carbon according to fundamental analysis.Creates a reduction environment when added to molten steel Can be used with coking materials such as coalMix bitumen with non-coking coals and mix with cokeCoke is often used in the sugar industry.It is also made from sulfur-free types or after desulfurization of a type of coke called needle coke, which is commonly used in electric arc melting furnaces.
Drilling mud application;Gilsonite is used in the production of mud and cement slurry for drillingDrilling fluids are used to cement oil wells
Advantages of drilling mud;The resulting slurry has a low density without adding too much waterCompatible with other additives and resistant to acids, bases and corrosive substancesResistance to sluggish premature moisteningThe use temperature is wideWhen oil wells are cemented, they cause sealing and voids in the wells due to their plastic flow properties.Resistant to oil solubilityClusters and colonies due to persistence and pressureResistant to medium pressures from dehydration,asiagilsonite but soft to deformation due to pressure
fuel use;Gilsonite jams, along with fuel compounds such as mazut and coal, have been used as fuel in thermal furnaces in the past. Today, this application is limited to low quality Gilsonite types
The use of Gilsonite in the foundry industry;Gilsonite is used as a carbonate additive in foundry sands, creating softer plates in gray iron moulds.Gilsonite charcoal is mixed with Sea and used as a special adhesive for foundry sand, which reduces errors in finishing the casting process.
Using Gilsonite in the chemical industry;Bitumen or Gilsonite has been used successfully to produce sealants and adhesives.It is a very good lubricant and can be obtained by combining with different resins.
Benefits of Adding Gilsonite to Refinery Bitumen;Reduce track finding (wheel treads) and other issues that cause asphalt to be lost when heavy traffic is affected by hot weather.It reduces the thermal sensitivity of bitumen, so it performs well at high temperatures as well as doing less damage at low temperatures.Adding Gilsonite is easy can be added directly into hot bitumen or mixed with asphalt.Stable soluble form that remains stable during storageAnother advantage is the use of Gilsonite as a MODIFIER. This advantage can be important in the hot asphalt production process and often for polymer problems.Ease of combining Gilsonite with other hot compoundsIt also reduces contracting operations.This performance is very economical and the غير مجاز مي باشدt of using Gilsonite is to add ethylene vinyl acetate (EVA) or styrene butadiene (SBS) rubber.
Gillsonite is the general name of a mineral oil hydrocarbon group with CAS number: 12002-43-6. In fact, when deep underground crude oil loses its volatile properties over time, the black solid is called bitumen. Gilsonite is also known as Bitumen, Bitumen, Asphalt, Mineral Asphalt, Uintait, Hard Asphalt and Zagronite. Gilsonite is black, luminous in bulk and similar to glass minerals, brittle and can pulverize. Gilsonite in nature in a solid form without crystalline pulp in the form of inorganic veins, black and tan below the soil surface. These veins are about 0.5 to 2 meters wide, sometimes up to 5.8 meters. These veins are usually parallel to each other and generally run from northwest to southeast. These veins are very long and can reach kilometers.
Gilsonite is soluble in organic solvents such as carbon disulfide, toluene and tetrachloroethylene, but insoluble in water and alcoholic solvents. Its high-quality variants contain 4-5% carbon, 2% hydrogen and 2% nitrogen, oxygen, sulfur and small amounts of metallic elements and 1-2% organic volatiles. The high proportion of carbon and nitrogen created special properties in Gilsonite. The molecular weight of Gilsonite كه is higher than other asphaltic products and synthesized resins, which is a polymer-like compound.
