Measuring Mixers for Labo Plastomill | 655
Mixer heating block, that is the sample kneading part of Labo Plastomill, contains 2 kneading blades rotating in same direction or two kneading blades rotating in different directions and resin temperature sensors.
Mixing and kneading of sample filled in the mixer proceeds as it receives heat and shear from the blade and its state of melting, dispersion, distribution, steadiness, deterioration, curing reaction, cross-linking, heat generation, etc. changes in various forms according to the characteristics of the sample.
Since these changes in state appear as change in the torque acting mechanically on the blade, the behavior of torque and resin temperature are continuously detected and displayed on the monitor.
In mixer test, processing characteristics such as gelling characteristic, dynamic thermal stability, curing characteristic, dispersion characteristic, etc. can be determined as index.
Moreover, since mechanically provided energy (MH/m3) consumed per unit volume is calculated, information regarding mixer scale up and comparison among samples can also be obtained. The middle size mixer (100cm3 or larger) is generally used to collect large quantity of kneaded substances as secondary sample in addition to conducting above-mentioned tests.
