Abstract Simple bio-based abrasive grinding wheel based on thermosetting resin
matrix was developed starting with condensed tannin and furfuryl alcohol, which
are mainly derived from forest and agricultural products like tree barks, wheat and
crops. Fourier transform infrared spectra (FTIR) signified the acidic conditions are
quiet efficient for the reaction of furfuryl alcohol, urea and glyoxal all together
and the -CH2-NH- and -CH2-O-CH(OH)- groups are predominating in cross-linking of the tannin-furfuryl alcohol-urea-glyoxal (TFUG) resin. The strengthening
contribution of the tannin was also confirmed by the preservation of its distinct
crystallinity using X-ray diffraction (XRD). Differential scanning calorimetry… More >
