Abstract
Provided is a method for the simultaneous determination of parameters, in particular of at least two, three or four parameters, of at least one resin layer applied to at least one carrier material by recording and evaluating at least one NIR spectrum in a wavelength range between 500 nm and 2500 nm, preferably between 700 nm and 2000 nm, more preferably between 900 nm and 1700 nm, and particularly advantageously between 1450 nm and 1550 nm, using at least one NIR measuring head, in particular at least one NIR multimeter head.
Claims25
A method for simultaneously determining at least two parameters of at least one paper layer impregnated with at least one resin in an impregnation plant, the method comprising:
- impregnating the at least one paper layer with the at least one resin in a production sequence of the impregnation plant;
- measuring, recording, and evaluating at least one NIR spectrum of the at least one paper layer impregnated with the at least one resin in a wavelength range between 500 nm and 2500 nm using at least one NIR multimeter measuring head;
- and
- simultaneously determining at least two parameters of the at least one paper layer impregnated with the at least one resin based on the at least one NIR spectrum,
- wherein the at least one NIR multimeter measuring head is connected to a control system for automatically controlling production conditions of the impregnation plant comprising at least one computer-aided evaluation unit and a database for processing and storing NIR data for the measured NIR spectra, and the method further comprises:
- in the evaluation unit, simultaneously determining the at least two parameters of the at least one paper layer impregnated with the at least one resin by an automated comparison of the stored NIR data for the measured NIR spectra for the at least one paper layer impregnated with the at least one resin with a calibration model created for the at least two parameters, and
- storing the at least two parameters of the at least one paper layer impregnated with the at least one resin in the database.

- storing the at least two parameters of the at least one paper layer impregnated with the at least one resin in the database, and
- wherein, the control system makes an automatic adjustment to the production sequence of the impregnation plant for the at least one paper layer impregnated with the at least one resin when the at least two parameters for the at least one paper layer impregnated with the at least one resin determined by the evaluation unit deviate from corresponding target values, and the adjustment comprises the control system automatically adjusting squeegees, squeegee rollers, a spreading quantity of the resin, and/or a temperature control of a dryer in the impregnation plant.
