Linear shrinkage

Person 1 In process A, the bulk density is 2.43 g/cm green and 3.84 fired. Calculate the volume shrinkage, linear shrinkage, and the densification ratio for this process. [Pg.706]

The oscillating jet method is not suitable for the study of liquid-air interfaces whose ages are in the range of tenths of a second, and an alternative method is based on the dependence of the shape of a falling column of liquid on its surface tension. Since the hydrostatic head, and hence the linear velocity, increases with h, the distance away from the nozzle, the cross-sectional area of the column must correspondingly decrease as a material balance requirement. The effect of surface tension is to oppose this shrinkage in cross section. The method is discussed in Refs. 110 and 111. A related method makes use of a falling sheet of liquid [112]. [Pg.34]

Like methylolureas, cycHc ureas are based on reactions between urea and formaldehyde however, the amino resin is cycHc rather than linear. Many cychc urea resins have been used in textile-finishing processes, particularly to achieve wrinkle resistance and shrinkage control, but the ones described below are the most commercially important. They ate all in use today to greater or lesser extents, depending on specific end requirements (see also Textiles, finishing). [Pg.329]

The linear thermal expansion of base-plate waxes should not exceed 0.8% at 25—40°C. It is desirable to invest any waxed-up case as soon after waxing is completed as possible. This minimises changes in articulation owing to tooth shift, and changes in palatal thickness owing to lifting of the palatal section by wax shrinkage caused by variations in room temperature or by the release of stress.

No data are available on casting shrinkage, but in alloys having the same approximate nickel and chromium contents, pattern-makers usually make allowances for roughly 3% linear casting shrinkage. [Pg.485]

Thermal-mechanical analysis (TMA) has proven a more reproducible measure of melt integrity [20]. The TMA test involves measuring the shape change of a separator under load while the temperature is linearly increased. Typically, separators show some shrinkage, then start to elongate, and finally break (see Fig. 5). [Pg.561]
