APOS GlueNIR – Reduce glue consumption in board production
APOS GlueNIR allows parallel measurement of solids content, molar ratio and viscosity of glue in board production.
Continuous online/inline measurement just before use
What is APOS GlueNIR?
APOS GlueNIR is an NIR application for online measurement of solids content, molar ratio and other parameters in glue.
ONLINE. No more tedious batch lab analyses!
Why APOS GlueNIR?
The system allows better control of emissions/formaldehyde and ideal board properties and real-time dosage of glue as a ratio of true solids content and atro mass of wood fibers. GlueNIR saves glue and pays for itself within a few months.
Turnkey delivery
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. The system needs to be serviced once a year and otherwise runs drift- and maintenance-free.
Potential with APOS GlueNIR
PAST: Individual analysis for glue / resin specification
Background:
- In the wood industry, amino plastic resin systems (melamine-urea-formaldehyde (MUF) or ureaformaldehyde (UF) resins) are used
- Properties of these resins / glues influence the process and the quality of the products
- Products are manufactured in smaller batches in resin / glue plants
- Specification takes place on individual samples after production
- Sampling hardly representative, so impractical to use for process management in board plant
- In addition, there is a mixing with old glue in the storage tank
- Molar ratio, viscosity, solids content, gel time are important glue / resin parameters
Potential with APOS GlueNIR
Benefits:
Savings potentials using APOS GlueNIR
Example calculation for line using 25t wood bone dry /h
Save glue and speed up production by measuring solids content and molar ratio of glue! Online, without any lab testing!
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.
