Benefits of the loop system:
Action on the chemical composition:
The principle of the Loop is to refine the cellular structure and to increase their number by a set of combined actions made on the Polymix (mixture of polyol and additives). By overhomogenizing the polyol with its additives and integrating air in very fine particles, its reactivity can be increased, which significantly improves the mix quality of the Isocianate/Polyol pair and, as a result, optimizes the reaction’s quality. Therefore, this function allows a better reticulation, which improves the mechanical characteristics of the polyurethane foam.
Action on the cellular structure:
The resistance of the matrix’s structure also depends on the fineness of the bubbles and their homogeneous distribution. The Loop due to its concept of associating the explosion of bubbles into very fine particles and several precise physical actions significantly improves the dispersion quality of the cells, enabling a finer structure of the matrix. Therefore, the gas doses can be reduced up to 50% of the total production flow rate.
To obtain this quality it is important to have a process of manufacturing which at first gives good results and constancy in the respect for the parameters. If the process has defects, Loop is going to amplify them because we are going to try to refine a heterogeneous cellular structure and we are going to increase the ability to react of the foam, all the conditions to damage the characteristics of the panel.
Description:
This machine consists of a steel framework holding all the components needed for its operations, such as motor pipes, pump, valves, tanks, control panel and instruments. It is a fully autonomous system, controlled via a Proface touch screen.
The gas particles are injected into a secondary circuit and distributed evenly throughout the raw material (polyol).
The touch screen control system provides start-up, production and weekend modes as well as constant display of the measured values, faults and help.
Technical characteristics:
- Max. flow rate: 160l/min
- Viscosity: Polyol 100—2500 mPas at 20° C
- Gas supply: 10 bar minimum—60 bar maximum
- Specific static mixing elements self cleaning
- Gear pumps with magnetic coupling
- Complete fluting with lids and valves
- Activators and air entries with non-return valves and air flow regulator
- Pressure Sensors
- Electric casket with frequency converter, connection, automaton and touch-sensitive screen
- Specific entries on the automaton for connecting with the production line
