Natural bitumen in drilling asphalt ink paint and foundry

Natural bitumen, produced from bituminous rocks and it is a change after more than millions of years of natural mineral precipitation , under pressure and geological changes in the form of mining Having broken from the fine granular powder , light brown , where the asphalt content of about 80% to 85% , the rest are kind of limestone minerals. Quality rock asphalt can be used as a better modifier.I. ATMD natural bitumen characteristics
High softening point can significantly improve the high temperature stability of asphalt pavement, improve the ability of pavement rutting. Nitrogen content of nitrogen element in the form of functional groups , can increase the viscosity of bitumen , enhanced oxidation resistance , adhesion and resistance make the cut off of the aggregate has been significantly improved, improved resistance to water damage ability asphalt pavement . Its molecular weight, when fused with the base asphalt at high temperature and small molecular , combined into a “semi- polymerization” effect.It has very strong anti-microbial erosion on the surface protective film formed naturally tight light amount , more durable surface to improve the speed of slowing down the aging and prolong the service life of the road .
natural bitumen is wax-free , high wax can damage the quality of asphalt .
natural bitumen manufacturing process is simple , easy construction.
by the modified base asphalt Buton rocks makes more stable performance .

Natural bitumen in Paint

A paint consisting essentially of 20 gallons of petroleum solvent, 10 gallons of linseed oil, 10 gallons turpentine, pounds of natural bitumen 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 subjecting natural bitumen to fractional distillation, said distillate product being that fraction which distills at a temperature range of about 430 F. to 438 F.

Natural bitumen in ink

Natural bitumen is widely used as the primary carbon black wetting agent for black news inks and headset and toner ink. ATDM resin competes advantageously with hydrocarbon resins, phenolic resins.

Natural bitumen in asphalt composition

We discovered that synthetic flux oil can contain and deliver asphaltite, such as gilsonite, more easily and readily to an asphalt to improve its properties. The synthetic flux oil includes the asphaltite and a carrier oil. Depending on the nature of the carrier oil, the synthetic flux oil may or may not need to be heated during mixing and incorporation into the asphalt.

Natural bitumen in construction

Natural bitumen cement compositions are disclosed which utilize petroleum asphalt, reactive oil and an elastomer. These compositions produce superior natural bitumen cement that can give low viscosity during application followed by high viscosity, toughness and tenacity after curing on the highway.

Natural bitumen in foundry

Natural bitumen, an additive for foundry sand preblends providing reduced smoke and other emissions, the additive comprising a mixture of one part iron oxide as one part of a highly volatile carbonaceous material, and four parts of metallurgical coke. The additive is used as one quarter of the foundry sand preblend, the other three quarters consisting essentially of clays.

What is bituminous coal?Bituminous coal is a naturally occurring combustible material consisting primarily of the element of Hydrogen and carbon. It also contains low percentages of solid, liquid, and gaseous hydrocarbons and/or other materials, such as compounds of nitrogen, sulphur, phosphor. Gilsonite is usually classified into subgroups known as bituminous material. The physical, chemical, and other properties of Gilsonite vary considerably from sample to sample.Origins of bituminous [...]

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 [...]
