Gilsonite In Foundry & Construction

Gilsonite Usage In Foundry & Construction

Gilsonite is combined with coal and other ingredients as an additive in foundry sands to ensure the quality of the molded part. In sand case, by adding Gilsonite and asphalts at approximately one-third the level of sea coal the pitch had the same 900°F (482.2°C) volatiles. At this level, loss on ignition with asphalt, and Gilsonite was less than 50% of that obtained with seacoal and pitch while the Gilsonite and asphalts evolved less total gas when compared to seacoal and pitch Gilsonite had the least visible smoke generated in the laboratory tests. The lower gas evolution should reduce ventilation load on the pouring floor. The physical property relationships developed in new sand mixes were confirmed by sand using Gilsonite as an additive. Casting finish off a Gilsonite mix has been equal to Seacoal.

For High-Value Iron Castings, Gilsonite Performs Like No Other.
Foundries around the world have known for decades that – when put to the fire of molten iron – Gilsonite brings high performance to your foundry sand.
For your complex, high-value iron castings, Natural Bitumen performs like no other carbon additive. Gilsonite naturally superior properties mean high-quality castings with better finish and fewer imperfections.

Asphalt has been the subject of exhaustive study to improve characteristics for use in paving. Various properties of asphalt are manipulated to produce a product that has the appropriate wear properties, rut resistance, fatigue and low temperature cracking resistance, adhesion strength, viscosity and pour point. Rut resistance is resistance to longitudinal surface depressions in the wheel paths. Adhesion strength is the maximum adhesion strength of the joint sealant and the joint reservoir, including but not limited to, between the aggregate and the binder.

Shove resistance is resistance to permanent, longitudinal displacement of a localized area of the pavement surface caused by traffic pushing against the pavement. Heavy hydrocarbon that can be derived from, without limitation, natural asphalt (Gilsonite), shale asphalt, bottoms from a solvent deasphalting process, hard asphalt, blown asphalt, stiff refined asphalt, a flux. Asphalt is usually the base ingredient for the primer and the binder.

A primer can be asphalt, fibers (including but not limited to, mineral or cellulose), processing agent (including but not limited to, oligomeric wax, carboxilated, derivative of oligiomeric wax, or low molecular weight polyolefin), polymeric or elastomeric additive, or asphalt-derived. A primer melts to the aggregate. Asphalt binders without polymers are referred to as “neat”.

Gilsonite In Coating

Gilsonite Usage In Coating

There are few prior art coating compositions which combine the highly desired characteristics of economy, low raw material cost and compatibility with most of the raw materials used in the paint, varnish and enamel industry, and at the same time are also highly resistant to acid and alkali materials, non-corrosive toward the surface upon which they are applied, weather-resistant and of high electrical insulating value. There is, however, one composition which possesses all of these properties. This composition is one containing gilsonite as a principal constituent. For example, a Gilsonite and drying oil composition possesses all of these desirable qualities to a considerable extent.

Gilsonite is one of the purest natural bitumens available and is used in the manufacture of black varnishes, coach varnishes, black baking enamels, japaris, insulating compositions and water-proofing compositions. Two counties in the State of Utah are the sole source of commercial quantities of gilsonite in this country. Gilsonite as mined in these counties varies in its properties from one deposit to another and its properties often vary. Within a given deposit. In addition, many of the more accesssible deposits are being depleted. Consequently, the industry is faced with the problem of providing a suitable replacement material for Gilsonite in such compositions.

Gilsonite is used as insulated coating for pipes. This material is a non-toxic gum with excellent adhesiveness. Anti-corrosion coatings which are chemically inert can be produced from Gilsonite. In the wood and carpentry industry, Gilsonite is used as a solidifying agent (glue). This material is waterproof and corrosion resistant. Since Gilsonite is a very hard resin, it produces very hard products.

Micronized Gilsonite Powder

Micronized Gilsonite Powder Description

HJ Oil Group Supplies Micronized Gilsonite powder with a diameter of 80 to 400 mesh and ashes from 0% to 25%.

The company is taking advantage of experts who are capable of processing Gilsonite lump to alter them to powder with the size 80 to 400 mesh and packing according to customer’s order.

Gilsonite is a Soft Rock, meaning that it can be simply made into Gilsonite Powder. A 200m2 industrial unit is sufficient to set up a grinding mill, while complimentary packaging equipment is also necessary to wrap Gilsonite into different packaging, from 1 MT jumbo bags to 25 kg worker bags.
The technology of grinding minerals is vast and advanced expertise which has been developed in different countries. The tricky part of Gilsonite pulverizing is about one of its principal characteristics, i.e. having BITUMEN CONTENT inside. Applying energy into natural bitumen releases the bitumen content, therefore taking the rock asphalt under grinding, makes it a sticky powder, especially if the temperature is not properly controlled during the process.
Depending on the method of grinding, Gilsonite can be made in different mesh sizes, starting from 30 to 400 for Simple crushing machinery. Mesh size goes up to 500 – 1000 Mesh in case a Fusion unit is added.
Still many claims to supply a 3,000 Mesh Gilsonite Product which is a myth, considering there is no economical way to measure such dust particle size.
Another challenge is an environmental hazard. Pollution resulting from grinding the natural bitumen can end up in stopping the facility from production by the authorities in many countries. Still, There are primitive (using back filters) and advanced ways (using output Catalysts) to rectify the issue.

Lump Gilsonite

Lump Gilsonite Description

Lump Gilsonite, or Natural Asphalt, Natural Bitumen is a natural, resinous hydrocarbon This natural asphalt is similar to a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. 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 reducing the content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous, taking the form of asphalt. It is a natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by a neutral agency. It is as bitumen created in the process of crude oil processing. It is native substances of variable color, hardness, and volatility, composed principally of the elements carbon and hydrogen and sometimes associated with mineral matter and essentially free of gas. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. Gilsonite is found below the earth’s surface in vertical veins or seams that are generally between two and six feet in width but can be as wide as 28 feet.
Due to the narrow mining face, Gilsonite is mined today, much like it was
50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.

Gilsonite Usage in Inks & Paints

Because of the unique properties of Gilsonite, it gives the paint an excellent bond to almost any material that needs to be protected from the elements. It is a critical high-performance, low-cost paint additive for anticorrosive paints, underbody paints, and pipe coatings.

The superior performance of Gilsonite means you can find it in the majority of wood stains produced in the U.S. In this application, the unique properties of Gilsonite make it both a binder to protect the wood, and a pigment that gives a deep, rich color that won’t fade over time. Gilsonite paint additive is Naturally Better and you just can’t get this performance with any other material—natural or synthetic.

A paint consisting essentially of 20 gallons of petroleum solvent, 10 gallons of linseed oil, 10 gallons turpentine, pounds ofGilsonite pigment, 4 gallons varnish mixture consisting of 17.8% pentaerythritol rosin ester, 30.8% dehydrated castor oil, 1.4% of a mixture of lead, cobalt and manganese naphthenates, 1-gallon wetting agent consisting essentially of salts of petroleum sulfonic acids, 2 quarts of drier, and 1 pint of a hydrocarbon silicon penetrating oil, obtained by heating a mixture of finely ground silicon dioxide under pressure to a temperature of about 300 F. with a distillate product obtained by subjectingGilsonite to fractional distillation, said distillate product being that fraction which distills at a temperature range of about 430 F. to 438 F.

Gilsonite is widely used as the primary carbon black wetting agent for black news inks and headset and toner inks. PUB Gilsonite Resin competes advantageously with hydrocarbon resins, phenolic resins.

Advantages of Using Gilsonite In Inks & Paints

• Superior binding properties for many materials
• UV light stability
• Fade-resistant transparent pigment gives a deep, rich color to wood stains

Gilsonite Usage In Asphalt

Gilsonite makes roads stronger to last longer.

As an asphalt binder modifier, the unique properties of Gilsonite make a road that is less susceptible to high-temperature and deformation performance issues. When these modified binders are used in recycled asphalt pavements, Gilsonite adds back what time has taken from the old asphalt, making it easier to use more of this recycled material. The Gilsonite-modified asphalt binder will produce a stronger road that can be thinner by nearly 20 percent compared with other pavements. For more information about this application, please contact us.

As an aggregate modifier, Gilsonite can be added directly at the hot mix plant with no additional equipment. The excellent bonding properties of Gilsonite will produce a high-strength, high-performance pavement that also resists water stripping.

Gilsonite

Gilsonite Description

Gilsonite is a naturally occurring glossy black asphaltic, solid hydrocarbon resin with low specific gravity. It occurs in its very pure natural state in a mineral called Uintaite. Gilsonite or Natural Asphalt is a natural, resinous hydrocarbon found in northeastern Utah. Natural Asphalt is a unique natural hydrocarbon high in asphaltenes and nitrogen compounds so it is a granular solid that is fully compatible with bitumen. It can be melted into hot bitumen, added during the hot-mix manufacturing process, or blended into a preservation treatment.

This natural asphalt is similar to a hard petroleum asphalt so it’s other names are natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, natural asphalt is frequently used to harden softer petroleum products. natural asphalt in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and it can easily crush into a dark brown powder.

Gilsonite is below the earth’s surface in vertical veins or seams that are generally between two and six feet in width but also can be as wide as 28 feet. The veins are nearly parallel to each other and they are in orient-shape in a northwest to southeast direction. They extend many miles in length and as deep as 1500 feet.  The vein will show up on the surface as a thin outcropping and gradually widen as it goes deeper. Due to the narrow mining face, natural asphalt is mined today, much like it was 50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.
