What is rheokinetics Rheokinetics, a contraction of the terms rheology and kinetics, sometimes referred to as chemorheology, is the science that studies the evolution of the rheological behavior of a system during the chemical reaction. Rheology and rheokinetics, what are the differences? If it is related to rheology, rheokinetics is a separate discipline with specific needs. In practice, rheology makes it possible to determine the macroscopic mechanical properties from a study based on the micro or nanoscopic structure of the material, such as the molecular size and the architecture of a polymer in solution or the size distribution. of particles in a solid suspension. Rheology consists in following the evolution of the viscosity of non-reactive products as a function of deformation, frequency or temperature. To do this, the most commonly used geometries are continuous rotation and oscillatory rotation which, through simple calculations, transform the values of torque and strain into viscosity. ​ However, this has disadvantages geometry upon reaching excessively high viscosity values, as is the case during a crosslinking reaction of an epoxy resin for example. ​ Thus, rheological analysis tools are unsuitable for analyzing the transition of reactive products from the liquid state to the viscoelastic solid state. Either they provide a single value (or only the start of the reaction) in the case of measurements in continuous rotation, or they provide an almost complete curve but at the cost of constant modifications of the frequency or of the deformation. Oscillatory translation Oscillatory translation (or linear oscillation) does not present the faults of the methods by rotation. Used for the study of blood clotting for almost a century, it was then transposed to the study of the coagulation of milk after the Second World War. In the 1970s, a standard allowing the gel time of polyester resins to be measured also uses this method with parameters adapted to this type of material. TROMBOMAT TROMBOTECH The advantages of oscillatory translation are multiple: a sollicitation at low frequency and low amplitude allowing not to disturb the current reaction; a robust mechanical system to protect the instrument during hardening of the material; a conservation of the test parameters from the start to the end of the reaction. Oscillatory translation is the only dynamic mechanical analysis method allowing such performance. Example of a curve obtained on an epoxy resin during a cup test (2mm thickness) Example of a curve showing the rennet-induced coagulation of milk during a test in a beaker (100 ml) at 40 ° C. Example of blood clottingduring a test in a hemolysis tube at 37 ° C. Par le passé, des appareils dont le nom contenait le préfixe Trombo- étaient basés sur cette méthode.

TESTS Rheochronos has a test laboratory and therefore benefits from the ability to perform rheokinetic measurements. ​ We can use standardized methods, internal methods or developed methods according to your needs. ​ The tests carried out provide you with relevant information on the characteristics of the products resulting from your production, your sourcing or new products in development. ​ Uncertainty about a new batch? Of a product stored beyond its expiration date? A doubt about storage conditions? ​ A problem during manufacture? A compound from a new supplier to test? ​ All of these reasons may cause you to need to perform testing on an ad hoc basis. ​ Contact us to know our prices and our support solutions.

BY USE Because laboratory tests can have many purposes, we offer models and their variations suitable for each use. QUALITY CONTROL MEASURES CLOSER TO PRODUCTION TOOLS. Quality control is an essential element when it comes to guaranteeing the quality of products. It is a crucial operation upstream of the production tools to know the quality of the raw materials. It is just as important downstream, to control production processes before shipment. As quality control varies from one company to another (product, application, standards) HKR-GT , HKR-GT + or HKR-DV may be suitable. Contact us so that we can together define the offer that best suits your needs. DEVELOPMENT OF NEW FORMULATIONS DESIGNING THE PRODUCTS OF TOMORROW. Formulators are constantly innovating to create future references for their catalogs by: improving an existing formula: performance / price ratio, processability, application of the European REACH regulation, elimination or reduction of the content of a toxic constituent (ingredient) or reducing its content; formulating a new formula (invention) on the basis of specifications specific to a client. Two models may be suitable depending on the test conditions: HKR-GT + for tests at ambient temperature (and external thermal control if applicable) or HKR-DV for total control of the test conditions. EDUCATION TRAIN FUTURE ENGINEERS AND TECHNICIANS. Use our equipment adapted to several areas of training: university training (high schools, engineering schools), vocational training, etc. For carrying out practical work, HKR-GT or HKR-GT + are the most suitable models. RESEARCH DEEPENING THE KNOWLEDGE OF CHEMIORHEOLOGY. Acquire new knowledge on the foundations of phenomena and observable facts, without considering a particular application or use. As research requires careful control of test conditions, HKR-DV is the best option for this type of use. TROMBOMAT TROMBOTECH
