Método para a secagem de espumas feitas de dispersões pu aquosas

The method for drying of foams involves the drying of moist foam that may have a water content of between 15 and 60 % gross weight with microwaves applied to it of around 2.0 to 3.0 GHz or between 0.8 to 1.5 GHz. Simultaneously, before or after, additional thermal drying may take place alongside the...

Zusammenfassung:The method for drying of foams involves the drying of moist foam that may have a water content of between 15 and 60 % gross weight with microwaves applied to it of around 2.0 to 3.0 GHz or between 0.8 to 1.5 GHz. Simultaneously, before or after, additional thermal drying may take place alongside the microwave drying. The moist foam may contain polyurethane dispersions and further components during foaming and which may have a content of between 40 to 63 % gross weight.
