Rheology can act as a bridge that links changes to the formulation with product performance. Advanced and correct rheological data can help to optimise products and process conditions, thereby saving costs and minimising potential waste. The first discussions were based on the properties and behaviors of several materials as asphalt, lubricants, paints, plastics and rubber. Nowadays, the scope is even wider. Significant advances have been made in rheometry for example, in fields like coatings, suspensions and polymers rheology.
To understand rheology it is important to know that ideal solids, also named Hooke solids, can deform elastically and the energy required for the deformation is fully recovered when the stresses are removed. Rheological additives are able to modify the flow, viscosity and deformation properties, according to different needs. The rheology also helps to explain the polymer extrusion and temperature influence in deformation process. All this progress, however, would not be possible without the advances in equipment, like rheometers and viscometers. These devices are used to evaluate how all these materials behavior under different temperature and stress levels, simulating some real industrial and/or handling conditions.
Rheology understanding is fundamental for everyone who desire good results in his formulations for coating application, polymer extrusion and molding and many more applications. It is important because..
- Rheological data helps to optimise formulations and process conditions to save costs and time
- It can help formulators preview some important impacts on coatings, inks or plastics performance
- Number of rheology instruments, it is important to know how they work & theories behind them
- Nowadays, the scope is even wider, significant advances have been made in rheometry science
The more a coating, ink, paint or polymer engineer knows about rheology, the raw-materials properties and the laws regarding the rheology mechanisms, higher will be the reached final product performance..
This is one of those technical trainings which is highly recommended for chemical industry professionals including:
- R&D chemist, formulators, chemical engineers
- Product developers, scientists, technicians, lab managers
- Specialist and professionals from coatings, polymers and related industries
