摘要:
The present invention relates to a method for detecting curing and/or the local distribution of curing of the binder material, in particular for detection of anomalies of the cured binder, in a mineral fibre product. The present invention also relates to a reagent, in particular for use in such a method and the use of this reagent in the quality control of bonded mineral fibre products.
摘要:
An aqueous binder composition comprises: (1) a water-soluble binder component obtainable by reacting at least one alkanolamine with at least one polycarboxylic acid or anhydride and, optionally, treating the reaction product with a base; (2) a soy protein product; and, optionally, one or more of the following binder components; (3) a sugar component; (4) urea. The binder composition is particularly suitable as a binder for mineral fibres or as an adhesive for particle board and other composites.
