Structural plastics

Packed-Bed Fixed-Film Systems These systems were originaUy termed anaerobic trickhng filters because the first systems were submerged columns filled with stones run under anaerobic conditions (Fig. 25-57). A wide variety of packed media is now used ranging in size from graniiles 40 mesh to 7.5-cm (3—in) stones. Many systems use open structure plastic packing similar to that used in aerobic trickhng filters. [Pg.2224]

Different structural materials have different thermal contraction coefficients, meaning that accommodations should be made for their different dimensions at cryogenic temperatures. If not, problems associated with safety (e.g., leaks) may arise. Generally, the contraction of most metals from room temperature (300 K) to a temperature close to the liquefaction temperature of hydrogen (20 K) is <1%, whereas the contraction for most common structural plastics is from 1% to 2.5% [23]. [Pg.542]

Oligosilsesquioxanes with long-chain alkyl substituents have been offered as water-repellents and adhesives for pearlite heat-insulating plates and materials and as damping fluids and structural plasticizers for polymeric ceramic materials which allow to control the properties of the latter in the manufacture of the items concerned. [Pg.234]

While polymer melts and non-cross-linked elastomers flow readily when stress is applied, structural plastics must resist irreversible deformation and behave as elastic solids when relatively small stresses are applied. These plastics are called ideal or Bingham plastics with their behavior described mathematically by... [Pg.462]

Another reason to consider a novel role for the cholinergic basal forebrain is that cholinergic axons exhibit exquisite structural plasticity, similar to that of monoaminergic axons, and in marked contrast to that of glutamatergic axons (Farris et ah, 1993 Woolf, 1996). Wholly new cholinergic axon branches bear-... [Pg.25]

It is evident from the above discussion that lignin is still a material of the future in the areas of structural plastics and as a source of chemicals. However, the ever-increasing demand for a clean environment hastens the day when lignin is used on a large industrial scale. This day is much nearer than was predicted only a few years ago. From this point of view, it is evident that research should continue and more funds should be allocated to research work on lignin modification. [Pg.207]
