Shrinkage aging effects

C-732 TM for ageing effects of artificial weathering on latex sealants. C-733 TM for volume shrinkage of latex sealants. [Pg.231]

These authors also highlighted the fact that the reduction in free volume on aging must lead to shrinkage of the sample during a creep measurement. Consequently, this effect opposes the deformation and negative creep may be seen in low-stress tests. When these were carried out the master curve constructed from the data at various T deviated from that expected, see Figure 14.10. Because aging effects led to an over-prediction of the strain when short-term data... [Pg.997]

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]

Incorporated in PP, P.R.48 4 often causes aging, which makes the plastic brittle and precludes the use of P.R.48 4 in this medium. The effect on PE is less noticeable. The shrinkage of PE extrusion products at higher processing temperatures is practically unaffected by P.R.48 4. [Pg.329]

The method of placement makes shoterete potentially more variable and more anisotropic than normal concrete. Consequently, the development of the physical and mechanical properties such as strength, shrinkage, permeability and durability is drastically different from those of normal concrete. The effects are particularly noticeable during the very early and later ages [107, 109, 117]. [Pg.375]

Three Italian men aged 39, 42, and 53 years with invasive prolactinomas took cabergoline 1.0-3.0 mg/week and all developed CSF rhinorrhea after 2-7 months (111). This was clearly a consequence of loss of the stopper effect of the tumor, owing to shrinkage, and in each case was successfully treated by endoscopic trans-sphenoidal surgery. [Pg.655]
