In this study, several samples of a common polymer (aniline-phenolformaldehyde)
we prepared by condensation polymerization method based
on aniline, phenol, formaldehyde and in the presence of a catalyst of
ammonia solution at different concentrations.
The present research aims at synthesizing micro-porous and fluorescent polymer by microwave assisted synthesis allowing to reduce preparation time of 3 days at 180 °C using conventional method.
The rheological behaviour in the molten state of Acrylo nitril– Butadine –
Styrene (ABS) according to temperature, shearing stress and shearing rate
have been studied. Measurements were made with a capillary viscosimeter for
the static properties.
The correction of experimental data has been carried out.
Viscosity decreases with increasing shear stress or shear rate in the nonnewtonian
flow high polymer systems. However, the variation of activation
energy with temperature at fixed shear rate is always less then at fixed shear
stress.
The recent synthesis of the new polymers has been profoundly affected by
the unique characteristics of Dimer Acid.
These polymers were made up following the condensation with
triethanolamine when was treated in melted phase.
We performed identifi
cation of the physical characteristics of the polymers
such as the molecular weight, in addition to the acid value and hydroxyl value.
Infrared spectroscopy have been used in identification of this polymer.
Also, the rheological behavior has been assessed thermally and shearing
stress by using capillary viscometer.
Our results revealed a reduction in the viscosity with increase of the
shearing stress as will as with rise in the temperature.
Researchers and scientists to ease due to electric power generation
using fossil fuel plants with environmental pollution is seeking, in the
discovery and improve the methods of generation using renewable
energies. Floating solar chimney technolog
y of the most promising
technologies that can be used in power stations with solar chimney is
considered.
The research aims to give results on a proposal to determine the
specifications for the plant of this kind in the climate of the city of Homs,
for example, and the study of the behavior of this station and analyze the
most important parameters affecting it. In this research study hydrothermal
behavior floating solar chimney in the climate of the city of
Homs by a program written in a language programming EES thermal
power station.
