Gilsonite uses in drilling asphalt ink paint and foundry

Gilsonite has an extremely wide range of uses; these uses have changed over time with new technology and industrial needs. Current uses of Gilsonite are discussed in the following subsections.

Gilsonite is oil well drilling mud additive

For many years, Gilsonite has been added to drilling fluids to stabilise boreholes through shale stratigraphic intervals, preventing borehole enlargement. It is plugs micro fractures, bedding plane voids, and pore spaces and forms a thin film on the borehole wall. Gilsonite is added at about 1 to 3 kg per barrel of drilling mud. It is also reduces drill string torque and drag, and thus reduces the likelihood of stuck drill strings Bore-Plate, a speciality product for this application, is a mixture of grades (75% to 85% of the formula), surfactants, and dispersants designed for use in water-based oil well drilling fluids. Oil Well Cementing is added to oil well cement for use in primary cementing of lost-circulation zones in surface, intermediate, and production pipe.

It also is used for secondary cementing such as squeezing, recementing above inadequate fill-up, and plugging back to reestablish drilling fluid circulation. It is used because of its low density, low water absorption, chemical inertness, mechanical strength, granular nature, and minor deformation under high pressure. These properties allow it to effectively enter, bridge, and seal lost-circulation zones. Typically 11 to 23 kg of Gilsonite is used per sack of cement.

Gilsonite is asphalt pavement binder modifier

Is added to asphalt paving mixes to Improve pavement performance. It is increases stiffness and viscosity of the binder Improves load-bearing capacity and reduces highway rutting Improves ductility and resistance to low-temperature cracking Increases durability of the pavement Improves workability of the mixture during paving. Typically 5% to 15% is added to the mixture’s binder.

Gilsonite asphalt driveway coat sealer

Preparations of Gilsonite, solvents, and other additives are used to coat weathered asphalt driveways, playgrounds, and other asphalt surfaces to improve appearance, reduce water infiltration, and slow deterioration of the asphalt pavement. Built-up Roofing Component is added to roofing asphalts. The compound acts as a water proofing agent and as an adhesive that binds layers of roofing felt together.

Gilsonite is stabilizer of foundry sand

Is an additive in sand mixtures used to make molds for casting gray iron and pig iron. Adding such useful material makes a better mold that imparts a smoother finish to the cast piece and is easier to remove from the cast item.

Ink Component Gilsonite

And Gilsonite resin, derived by solvent extraction of raw material is used as carbon black wetting agents for black news ink and heat set and gravure ink. In addition to wetting and dispersing the carbon black pigment, The resin binds the pigment to the paper, yielding high-gloss print that resists rubbing off. It can be mixed with other natural and synthetic oils, resins, and other additives to yield ink suitable for different types of printing presses and printing applications.

It is typically comprises 2% to 5% of ink formulations. Refined resin issued in offset printing ink in concentrations of 15% or more to replace more expensive resins. Miscellaneous Applications is used as an organic fuel in fireworks; for manufacture of high purity carbon electrodes in the nuclear industry; as a binder in metallurgical additives and refractories; and in manufacture of con-tact and hot melt adhesives, friction products, and pipe coatings.

Gilsonite component

Is added to bitumen-based paints to increase hardness, adhesion, UV stability, and water and chemical resistance. Paint formulations are often used on automobile frames and radiators. It is also an ingredient in wood stains.

Natural asphalt is derived from the natural mutation of petroleum. This mutation happened a million years again under the influence of bacteria. This bacterial decomposition of petroleum resulted in reduce content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous , taking the form of asphalt. It is natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by natural agency. It is as bitumen created in the [...]
