Claims38
A method for determining a characteristic value for a binding force potential of paper fibers in a fibrous suspension, the method comprising:
- measuring an air content of the fibrous suspension;
- and
- deriving the characteristic value from the measuring,
- wherein the measuring comprises measuring the air content at a measuring point arranged before the fibrous suspension is subjected to deaeration.
A method for determining a characteristic value for a binding force potential of paper fibers in a fibrous suspension, the method comprising:
- measuring an air content of the fibrous suspension;
- deriving the characteristic value from the measuring;
- and
- correcting a deviation of the characteristic value,
- wherein the measuring and correcting occurs before the fibrous suspension is fed to a headbox of a paper machine.
A method for determining a characteristic value for a binding force potential of paper fibers in a fibrous suspension, the method comprising:
- feeding the fibrous suspension to a paper machine;
- measuring an air content of the fibrous suspension before the feeding;
- and
- controlling the characteristic value based upon the measuring,
- wherein the measuring and the controlling occurs before the fibrous suspension is fed to the paper machine.
A system for determining a characteristic value for a binding force potential of paper fibers in a fibrous suspension, the system comprising:
- a mixing device which mixes a prepared fiber stock and water to form the fibrous suspension;
- a deaeration device which removes air from the fibrous suspension;
- a measuring device which measures an air content of the fibrous suspension before the deaeration device;
- a proportioning pump;
- and
- a regulator connected to the measuring device and the proportioning pump,
- wherein the system determines the characteristic value for a binding force potential.
