A standardized steel ball is placed at the center of the sample and the water bath is heated at a controlled rate. The temperature at the instant the steel ball reaches the bottom of the vessel is recorded as the softening point. 4.4.1.17 Metals Content The metals content of petroleum and...

This link has been established for unmodified bitumen, but how long this equivalence is depends on several parameters, such as void content, climate, and composition of the binder (Anderson, 1999; Verhasselt, 1999; Farcas, 1996). Recently, a study of several experimental pavements with ...

The residual biomass ash constitutes the remaining material at the bottom of the pile. To reduce the moisture in the CS, it is critical to sun-dry it first. Moisture content in control CS bio-oil was found to be between 6 and 8% by weight in the initial research. Table 3 shows the ...

This was to reduce the lubricant content by the amount of the binder addition. Pore-free density calculations had suggested that, depending on the amount of the binder addition, this could result in density increases of as much as 0.10 g/cm3 versus the usual...
mechanical properties when integrated into the carbon support and catalyst. Manipulating the polymer binder content of the catalyst layers enables control of the hydrophobicity and hydrophilicity27. In particular, increasing the polymer binder content can increase the durability by preventing H3PO4flooding...

Effects of binder content on the morphology and electrochemical properties of solvent-free electrodes The manufacturing process of solvent-free electrodes is shown in Fig. 1, mainly including electrostatic coating, thermal treatment, pressure-based rolling and other steps. The specific details can be fo...
