TM20 Hi-Tech: From Maris experience a high-performances laboratory extruder
During the last years the number of trials at Maris Technological Centre has been constantly growing. Such trials are generally carried out in cooperation with the technicians and researchers of the different compounding sectors, namely techno-polymers, reactive extrusion, hot-melt, rubbers etc. A fundamental aspect for the good result of the trials is to analyse both the chemists' necessity who study the formulation aspects (feasibility with small quantities of raw materials and easy changeover of machine configuration) and the needs of the process technologists, who are interested in getting indications on the influence of the process parameters concerning the morphological and physic-chemical characteristics of the modified compounds. In both cases, it is of utmost importance to monitor the process parameters in order to elaborate an energy balance and a first, even though approximate, estimate of the scale up. The TM20 Hi-Tech is the synthesis of 40-years Maris experience in co-rotating twin-screw extruders manufacturing and it satisfies the above mentioned requirements. It follows perfectly the actual industrial tendencies which transfer to the production the experiences carried out in the laboratory. The TM20 Hi-Tech extruder has been designed and manufactured for research activity, featuring at the same time the quality, operational and performance characteristics typical of production equipments, so that it can reproduce, in a reduced scale, the behaviours and the performances.
Maris TM20 Hi-Tech co-rotating twin-screw extruder is suitable to verify and analyze all processes which have to be realized on industrial scale on the production lines, such as:
- Polymers synthesis
-Hot-melt and adhesives
-Masterbatch of pigments and/or additives
-Reduction of monomers and/or solvents content
- Rubber mixing
- Rubber recycling
Technical characteristics of TM20 Hi-Tech
One of the most interesting aspects of the TM20 Hi-Tech is the flexibility which allows fast changes of configuration with respect to the raw materials introduced and the type of process. This can be easily done thanks to interchangeable and modular mechanical components, which do not require the intervention of specialized mechanical technicians.The machine has been designed and manufactured for laboratory purposes, it is highly noiselessness and therefore it is suitable for environments other than the industrial ones, such as educational and research structures.The gearbox is lubricated in oil bath. The barrel cooling is operated by a closed loop water circuit which, starting from a main distributor, cools separately each single part and it is heated by means of electrical resistances. The construction materials of barrels and screw elements can be chosen among a wide range of nitrited, anti-corrosion and anti-wearing steel. The screw geometry is self cleaning and two lobes design.
