Xem 1-4 trên 4 kết quả Polymer rheology
  • Rheology involves the study of the deformation and flow of matter. The goal is to establish relationships between stress and deformation for (non-Newtonian) materials where neither Newton's law nor Hooke's law suffice to explain their mechanical behaviour. Many materials exhibit a non-Newtonian behaviour and the area is relevant in many fields of study from industrial to technological applications such as concrete technology, geology, polymers and composites, plastics processing, paint flow, hemorheology, cosmetics, adhesives, etc ......

  • Number of the equipments used in everyday life remarkably increased after the invention of synthetic polymers, especially of styrene-butadiene rubber in 1930 and of PVC in 1936, and thanks to fast-developing polymer technologies. Polymers are light, cheap and ductile inert materials, which have good mechanical and thermal properties, suitable to use for various purposes and are highly resistant to corrosion. Thanks to such properties, they play an essential and ubiquitous role in many industrial fields.

  • The simplest drilling fluid is a dirty mixture of water and clay, often referred to as mud. The drilling fluid in the drilling process can be seen as the equivalent to the blood in the human body, the mud pump is the heart, and the drilled out shale (cuttings) represent the slag products. At the surface, we find the mud cleaning system which corresponds to the kidney and the lungs. In the mud cleaning system the cuttings are removed by means of a sieve, the shale shaker.
