| Résumé : |
The ZiFoam air lock permits physical foaming over a wide bandwidth of raw materials. It can be retrofitted even to existing machines and used for small to large material throughputs. It is easy to use. |
| Note de contenu : |
- Three variants of physical foaming
- Two Buffers, one air lock and two valves
- Flexible and easy to adapt
- Emergency concept included
- Invaluable empirical values
- Fig. 1 : The three principles of physical foaming. The aforementioned trade names are from Trexel, Wittmann Battenfeld, Arburg, Zimmermann and ProTec Polymer Processing
- Fig. 2 : Construction of the ZiFoam air lock : The functional principle requires two valves
- Fig. 3 : The advantages and prerequisites – including two seals to maintain the gas pressure – for operating the ZiFoam air lock
- Fig. 4 : The foam structure is influenced by factors such as the type and amount of gas and the polymer used
- Table : The achievable throughput depends on the air lock diameter |
