Estimating the term…
A device for the batch reactive mixing and degassing of thermosetting polymers, such as polyurethane or similar, comprising at least one hermetically sealable container (1) in which the batch of thermosetting polymers is to be placed, a rotary plate (2) on which a satellite rotary plate is rotatably mounted, the container (1) being placed on said satellite rotary plate in order to cause said container (1) to rotate and to revolve, first means for driving the rotary plate (2) and second means for driving the satellite rotary plate, and means (3) for placing the container (1) under vacuum; said device is noteworthy in that it comprises means for controlling the first means for driving the rotary plate (2) providing a speed of revolution of the container (1) and a second means for driving the satellite rotary plate providing a speed of rotation of said container (1), said control means being capable of continuously varying the speed of revolution and the speed of rotation of the container (1) independently of one another. A process for the batch reactive mixing and degassing of thermosetting polymers.
A device for the batch reactive mixing and degassing of thermosetting polymers, comprising at least one hermetically sealable container in which the batch of thermosetting polymers is to be placed, a rotary plate on which a satellite rotary plate is rotatably mounted, the container being placed on said satellite rotary plate in order to cause said container to rotate and to revolve, first means for driving the rotary plate and second means for driving the satellite rotary plate, and means for placing the container under vacuum, wherein the device comprises means for controlling the first means for driving the rotary plate providing a speed of revolution of the container and a second means for driving the satellite rotary plate providing a speed of rotation of said container, said control means being capable of continuously varying the speed of revolution and the speed of rotation of the container independently of one another,
A process for the batch reactive mixing and degassing of thermosetting polymers, comprising at least the following steps of introducing the components of the batch of thermosetting polymers into at least one hermetically closed container, placing said container under vacuum and setting the container in rotation and in revolution for a mixing and degassing cycle, wherein, during said mixing and degassing cycle, the speed of rotation and the speed of revolution of the container are continuously varied independently of one another,
