Reduce glue consumption in board production!
APOS GlueNIR allows parallel measurement of solids content, molar ratio and viscosity of glue in board production. ONLINE. No more tedious batch lab analyses.
The system allows better control of emissions/formaldehyde, ideal board properties and real-time dosing of glue as a ratio of true solids content and bone dry mass of wood fibres. GlueNIR saves glue and pays for itself within a few months.
APOS GlueNIR is an NIR application for online measurement of solids content, molar ratio and other parameters in glue. These parameters are usually unknown, as each batch is analysed in the manufacturing plant (externally or on the premises of the panel plant), but often there is a change in the glue actually added to the production due to mixing, ageing, etc. The panel plant, which doses its glue based on the solids content, does not know the actual glue content. Consequently, the panel plant can not dose accurately and often over- or under-doses with correspondingly unnecessary glue consumption or poor panel quality.
GlueNIR measures the values in real time and allows online adjustment of glue dosage, eliminating the need for laboratory analysis. In addition, GlueNIR allows measurement of the molar ratio to control formaldehyde emissions.
The APOS transflectance probe for liquids is installed directly in the pipeline with a flange piece supplied. The flange allows the probe to be removed during operation and also has a tap for sampling, e.g. to validate the system during maintenance or to develop calibrations for further parameters together with customers.
All measured values are recorded in order to be able to trace product/emission changes afterwards. All standard APOS interfaces are available. The values for solids content and molar ratio can be passed on in real time, e.g. for automatic optimisation of gluing.
Like all APOS systems, GlueNIR is delivered turnkey, i.e. the customer does not need to build up any know-how on the subject of system and calibration. To install the flange, which does not require a bypass, the pipeline must be switched off. The probe and the system itself can then be installed at any time. The system needs to be serviced once a year and otherwise runs drift- and maintenance-free.
