Transformation into PPV could be achieved by elimination of the silyloxy group followed by thermal treatment or treating the precursor polymer with acid.
22.
That aspect allows classification of EBM with selective laser melting ( SLM ) where competing technologies like DMLS require thermal treatment after fabrication.
23.
Often, mechanical and thermal treatments are combined in what are known as thermo-mechanical treatments for better properties and more efficient processing of materials.
24.
Optimal extraction is possible only if the initial glass composition and thermal treatment are chosen such that combine structures form, and not droplet structures.
25.
Further thermal treatment of the polyamideimide polymer increases molecular weight and causes the amic acid groups to form imides with the evolution of water.
26.
By a thermal treatment, an interpenetration structure is generated, which results from a spinodal decomposition of the sodium-rich borate phase and the silica phase.
27.
Their investigations showed that not only the chemical stability can be influenced by thermal treatment but also density, refractive index, thermal expansion and viscosity.
28.
For $ 25 to $ 40 a ton, ESMI's thermal treatment process virtually erases the liability associated with owning contaminated sites by recycling the soil.
29.
The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres.
30.
Thermal treatment of highly plastic soils requires pretreatment, such as shredding or blending with more friable soils or other amendments ( e . g . gypsum ).
