FCR-R - Rheometer

FCR-R - Rheometer

Specifically designed for the synthetic fiber production industry, the Dynisco FCR-R series can be configured to measure a range of apparent shear viscosities, dual melt flow rate, simultaneous melt flow rate and extensional viscosities using the Cogswell Equations. The FCR-R system consists of two parts: a rheometer head and a rheometer control unit (RCU). The rheometer head is connected directly to the process which samples, conditions, and measures the melt viscosity of the molten resin through two separate dies. The RCU controls the rheometer test parameters (temperature, pressure and rate) and takes in data from the measurement head as well as provides outputs of computed results.

Features:

■ On-line apparent viscosities over a broad shear rate range
■ Unique dual capillary design with return stream
 On-line measurements of polymer extensional properties
 Data exchange by analog and digital input/outputs
■ Simple calibration

FCR - The Flow Characterization Rheometer



DYNISCO Polymer Test is a world leader in the field of on-line rheological measurements for the plastics industry. Specifically designed for the thermoplastics resin industry, the FCR (Flow Characterization Rheometer) provides continuous measurements of the melt flow or apparent viscosity directly on the manufacturing process. The FCR system consists of two parts: 1.) The Rheometer, connected directly to the process, which samples, conditions, and measures the flow of the molten resin through two separate dies, and 2.) The RCU (Rheometer Control Unit) that controls the rheometer test para-meters, takes in data from the mea-surement head, and provides outputs of computed results. lt can provide communications to an external distributed control system. The FCR can be configured to measure dual melt flow rates, simultaneous MFR and apparent viscosity, a range of apparent shear viscosities, and extensional viscosities using the Cogswell Equations. 
 

Rheometer Control Unit

The Rheometer Control Unit is contained in a NEMA 4 (IP 54) box that may be located in the control room or on the process floor. Programming of the control functions and output displays are achieved via a local color display with a touch screen interface. The RCU can communicate with a Distributed Control System (DCS) through its analog and serial outputs. The RCU operates independently and will continue its control and analysis functions in the event of a DCS failure.

LME - Laboratory Mixing Extruder

The Dynisco Polymer Test LME Laboratory Mixing Extruder is a unique laboratory tool developed to evaluate the processability of a variety of plastics and rubbers prior to production. From very fine powders to coarse materials, the LME will meet many extruding needs. The LME possesses a movable header and dial gage that allows for constant mixer adjustability. While in operation, the rotational shearing (mixing) is controlled by adjusting the distance between the end of the rotor and the inside header.
