Abstract: As we know, the medium density fiberboard prepared from natural
sticky matter which is generated from the lignin activated through
laccase-mediator system has been an effective solution to the problem of
free formaldehyde in forestry industry. Therefore, based on the premier
experiments, this paper has studied the carbon reservation in medium density
fiberboard through artificial accelerated aging, and drew the conclusion
that the carbon reservation in medium density fiberboard prepared from the
wood fiber which is activated through laccase-mediator system is relatively
higher than any other board. Furthermore, when the variation during
artificial accelerated aging is relatively small, the variation of chromatic
value bears evident otherness with control samples. This is because
laccase-mediator system has modified some chromophore and auxochrome.
Meanwhile, the study found that the lower the carbon reservation, the
smaller the initial contact angle, the higher the wettability, and the more
perishable the board will be. Nevertheless, the initial contact angle of
medium density fiberboard prepared with laccase-mediator system varies
little, and begins to stabilize a while after.
