For the production of Rockwool products a resin based on phenol-formaldehyde
is used to bind the fibres together and give form-stable products.
The amount of binder has an impact on both mechanical and physical
properties of the products. Further it influence emissions and production
costs. Knowledge about how much of the applied binder is "active" is therefore
very important.
We know that far from all binder is used for the cross-linking of the fibres, but very little is known about how much is the "active" part of the binder and even less about how the binder is distributed on the fibres.
The aim of the project is therefore to develop a tool, based on image analysis and microscope techniques that can provide these figures. The project may involve optical or SEM microscope techniques, however based on experience until now probably the SEM is the best tool.
The project should consist of one or more of the following parts:
Define a classification system for the distribution of binder on the
fibres
Optimise microscope techniques that makes it possible visually to separate
the binder from the fibres
Develop routines for the image analysis. The image analysis tool should
be based on equipment compatible with SIS imaging software (C++).
