· Abstract. The applicability of coal tar pitch and petroleum bitumen to the production of thermally expanded graphite was studied. The dependence of the coefficient of thermal expansion and the specific surface area on the amount of added substances was examined.
· Materials. Mastic specimens were prepared with different sand–bitumen ratios and volumes of conductive particles. Five different sizes (<, –, –, –, – mm) of natural silica mineral, with density g/cm 3, were mixed to have uniform bitumen used was 70/100 pen, obtained from Kuwait Petroleum, with density g/cm 3.

the soft bitumen is heated to a temperature of 70°100° C., brought to a highly fluid form and again with intensive mixing introduced slowly after the hard bitumen has been added, and the carbon paste is mixed further for at most 60 minutes at the temperature to which the solids fraction was heated, then removed from the mixer and cooled.
Solids/Liquids Mixing Successful mixing of solids and liquids can often be achieved using a classic stirring process. The convenient, robust and flexibly equipped IKA stirrers are optimally suited for solidliquid mixing when solid particles can be dissolved or easily moistened in the liquid.
The mixing and kneading use a doublestirring, doubleheating 2000liter preheating kneader. Each time, 2 tons of paste can be kneaded, and the kneading cycle is 4050 minutes. The kneaded paste is discharged into the movable bottom paste box, and is sent to the paste uniform temperature box by the electric flatbed trolley and the bridge crane for uniform temperature treatment.
· 10ml of bitumen and 2g of graphite. Result 5001k/cm Ohms; Notes. Additional graphite was added to the existing solution after the sample trace was drawn. At 2g of graphite the mixture was thick and difficult to mix and manipulate with a the toothpick I used to lay down the test trace. Paint thinner should be added to the mixture and tested ...

· Mixing graphene into road surface materials. Protecting vehicle restraint systems We have over 7,500 miles of safety barrier around the country and most of these are made of steel. To keep these barriers in good condition we're looking at whether graphene can be used as a protective coating. This would help the barriers to last longer.
Mixing Mixing is mankind's oldest process. Mixtures allow for substances of the nature to be put to good use. Most food, personal hygiene products and remedies are the results of a mixing process. In the past, mixing difficulties have occurred when substances were hard to mix, or the stability of a mixture was either not achieved or poorly ...
Pyrolytic carbon black (CB p) from scrap tire pyrolysis is a potential modifier for the bitumen industry. Binders containing different contents of CB p were prepared and experimentally investigated to examine the effects of CB p on the electrical and
