Gilsonite exported in high quantity since 2013

Due increase of crude price and then bitumen price Chinese started to buy Gilsonite from Iran again in high volume.Normally they are buying in raw form and pulverizing in very fine particle size to save some cost and control the quality.On September and October compare other months since 2013 till today,Iranian exporter suppiled Gilsonite based on 7000MT lump to Qingdao port packed in 1000Kg jumbo bag.On end of October and Novermber more than 10000MT booked and in high season of [...]

Gilsonite used in lithium base batteries and duration of charge decreased to just 5 minutes

The Rice lab of chemist James Tour developed anodes comprising porous carbon made from gilsonite that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density.Above image -Scanning electron microscope images show an anode of gilsonite, graphene nanoribbons and lithium at left and the same [...]

Gilsonite in self heating asphalt repair system

Cracks in asphalt are a common sight, but a pain to repair. It is expensive and because the roads need to be closed down for construction, traffic jams occur. Researchers at polymer institute of research and development in Iran are working on a solution by creating pothole proof, self-healing asphalt, which can be mended using a magnet field.Bitumen is a sticky, viscous black binder used in road construction, made from petroleum. The bitumen is mixed with [...]

How many tons of Gilsonite Iran and USA export to worldwide market?

Since American Gilsonite bankrupted and closed,most of buyer shift to Iran Gilsonite and started to procure the material from Iran market.Becuase of negative reports of American Gilsonite on Iran Gilsonite,most of buyers hesitate to even test it but step by step buyers unstrstood Iran quality is much higher than American and now they are  importing volume goods.The picture is visit of American at Iran Gilsonite mines! American gilsoniteAmerican Gilsonite exported annually [...]

Gilsonite

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 additiveFor 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 [...]

Foundry

Gilsonite foundry sand help:1. Reduce imperfections due to the rapid reaction between the silica sand mold and the oxidized surface of molten iron.2. Improve sand peel from casting at shakeout.3.Produce smoother, cleaner casting surface.4. Minimise imperfections, casting losses, scrap.Foundry gilsonite additivesDuring pouring, the gases given off from the gilsonite which is carbonaceous additives form a gaseous film which prevents the molten metal from making direct contact with [...]

Asphalt

Gilsonite asphalt grade is natural occurring hydrocarbon substances characterized by a high softening point (above 110° C) in the class known as asphaltite. They are mined much like other minerals and sold essentially in their native state. They are fully compatible with asphalt and have long been known as asphalt hardeners and reinforcing agents. Gilsonite applicable in asphalt is currently sold all over the world as an asphalt modifier in the form of a dry bulk solid granular [...]

Paint

Maximum water and weather resistance is obtained by using a paint containing gilsonite coat and the gas-proofed tung or oiticica (or mixtures of the two) oil without the addition of any other drying oil, but it is found that while this combination is commercially usable, it is difficult to brush, and it is preferred to add a viscosity reducing drying oil. For this purpose it is found that perilla oil is particularly satisfactory. Other drying oils such as linseed, soya bean, sunflower seed, [...]

Ink

ATDM Gilsonite Ink grade is a quick drying high gloss and corrosion resistant asphalt enamel. It is using for fully resistance to water, acids, alkalis, electrolysis and natural elements.Gilsonite ink powder is readily soluble without heating in aromatic solvents (Benzene, Toluene, Xylene) and in most chlorinated solvents. It is also soluble without heating in aliphatic and low aromatic solvents (VMP and other Naphtha, Ink Oils and Mineral Spirits), but mixing time is longer. Without heating, [...]

Construction

Gilsonite 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, [...]

Drilling fluid

The invention relates to a composition comprising an drilling Gilsonite HPHT fluid loss control aid, stable at elevated temperatures and which also acts as an excellent shale stabilizer, bore hold lubricant, sealant for depleted sand, and wall cake conditioner. The HPHT gilsonite fluid loss control aid broadly comprises a Gilsonite (asphaltite, asfaltit,Gilsonita,uintaite, natural asphalt, natural bitumen) which also contains a surfactant such as a nonionic surfactant. The HPHT [...]
