Container Mixers SERIE

For the manufacturing of Powder Coatings there is required a pre-mix feedstock for the extruders that is a complete homogeneous mix of all the raw materials to be fed into the extruder. The FX series of container mixers provide the best alternative to conventional high speed mixers when production conditions require a high versatility and a wide range of different products to be mixed with the same mixer. Thanks to the container mixer special design divided into two separate units, mixing head and portable container, the cleaning time between batches is minimized therefore the risk of contamination too when switching from one type of production to another. Mix, storage and transportation are optimized by directly using the same containers that can be easily inserted in a dosing system either to a weighing scale or an extruder feeder. The container mixers FX are also ideal for post-production mixing with metallic pigments (Metallic Blending) ensuring the distribution of pigments in a safe and controlled environment inert by nitrogen.

Cooling / batch The discharged hot mix must be cooled as quickly as possible (25 C) and this is achieved using a separate low intensity cooler outfitted with cooling jacket wit water circulation to reduce the temperature of the mass. In most cases the bonded amount is a small part of a larger batch, then the cooler can also mix up to 3 batches simultaneously from the bonde. Sieving Since the powder coating is subjected to heat during the bonding process, and as such may be agglomerated, it is necessary to sieve the final product to remove any eventual agglomerates. A sieve mesh from 130-150 microns is usually sufficient. The final requirements of an optimal bonded coating are: excellent recycling of powder during the paint process thanks to the intimate bond between the metallic pigment and the base powder. No separation of the powder coating during the spray application, homogeneous application of the metallic effect to the piece.

E-BOND systems

System In powder coatings production the main difficulty is to find the optimal transition temperature for melting between metal and polymer particles, in order to obtain the best result in terms of quality of bonded product. Usually, a procedure to determine this temperature is obtained using the differential scanning calorimetry (DSC), a tool that analyzes powders and allows to estimate the phase diagram of the the part under testing and fix consequently the Bonding temperature of the mixer. Heat Capacity Temperature METALLIC BONDING

The DSC, however, only analyzes a small sample in its optimal state, which is completely different from the actual conditions inside the Bonding tank. For this reason, we tried to monitor the optimum temperature for Bonding during the mixing process, creating a phase diagram in real time. This has been possible thanks to the development of our function E-BOND, which is able to determine the density of the material and figure out with its variation if the same is in fusion, and therefore it is possible to start the bonding process at the correct temperature. Equally critical is to keep the constant temperature transition through the automatic speed modulation. The EBOND function, after the first few months of monitoring and development, has proved to be extremely effective: in fact we found that our glass transition temperature TG and the Bonding temperature TB were aligned with those obtained with the phase diagram of the DSC. METALLIC BONDING THE ADVANTAGES OF THE FUNCTION It is possible to take advantage of this function by performing an upgrade of the mixing plant, which will allow to: Reduce the required timing for the Bonding cycle. Obtain a perfect finish of the bonderized material. Avoid the risk of human error, with a fully automated process.
