Mixing and blending is a time of critical processes, materials, where the end point of the mixture condition of product acceptance. Viscosity of the liquid and semi-solids may be the main criteria for the flow behavior is crucial that the product is ready. Or cough medicine syrup texture or gel coat used on tablets, yield, process managers need a reliable method to know that the mix is ??good to go. "
Common method for determining the acceptable end-point during the mixing and blending, or grab sample monitoring or testing. Could easily have been based on the production floor and competence of personnel, to the best decision based on previous works. Grab sample test adds additional assurance of product acceptance, but it takes time to perform and can increase the overall processing time.
A typical grab sample tests for the viscosity of the sample and running a specific test method, procedure, or a mixture of the reservoir near the production floor or close to the quality control laboratory.
Which is a popular choice, as the instrument of measuring viscosity temperature control at a time. Temperature measurement / control the importance of selective prosecution test deserves its own discussion, because the material flow behavior and the small temperature changes can vary considerably.The former is usually a small cost of the latter. If you get the test results of the production floor of the turnaround time is important, then grab sample path. If you have lost money in lost time, and on-line viscosity measurement is worth considering.
Yet it is a greater resistance to measures that can work right, or the mixture in the tank and to provide continuous measurement of viscosity at mix / blend.If you get the test results of the production floor of the turnaround time is important, then grab sample path. If you have lost money in lost time, and on-line viscosity measurement is worth considering.
Figure 2 shows a portable viscometer, which can be inserted manually into the tank when it is necessary that the instantaneous viscosity reading.
Figure 3 shows, on-line viscometer that can be mounted directly into the circulation loop continuous viscosity sensing tank. The latter method has the additional advantage that automatic feedback control is possible. Process can be independently adjusted, measured as the viscosity deviates from the desired value, or by adding the adjustment components (for example, thickeners, water, or by adjusting the control parameters (eg, mixing speed and time).
Could easily have been based on the production floor and competence of personnel, to the best decision based on previous works. Grab sample test adds additional assurance of product acceptance, but it takes time to perform and can increase the overall processing time.
Grab sample vs. on-line viscosity measurement tradeof investment account. The former is usually a small cost of the latter. If you get the test results of the production floor of the turnaround time is important, then grab sample path. If you have lost money in lost time, and on-line viscosity measurement is worth considering. Or if the end point of the viscosity can not be exceeded for any reason, then the on-line measurement may be the only way to go.
