Abstract

More and more gravida abortion has been induced by indoor formaldehyde, and are severely threat public health. To fundamentally eliminate indoor formaldehyde pollution, wood fiber was pretreated by oxidation, biochemically binded during hot press, and analyzed by FT-IR and SEM. The results shown that the bond strength of biochemically binded boards was higher during the SYG pretreat than during the SQG pretreat. SEM analysis showed that the broke biochemically binded boards by SYG pretreat relative to SQG pretreat, the length of bulgy fiber was more consistent, the interface was more inseparable, cavitationis was lower, fracture behavior was ductile rupture. FT-IR spectrum showed that the absorbance of many connection binds such as –OH increased during the SYG pretreat, and it could be inferred that more binds were produced and played the role of molecular crosslinking. Anyhow, it suggested that the SYG pretreated was better than the SQG pretreated for the biochemically binded boards whose bond strength reached the maximum value 0.72 MPa (SQG) and 0.27 MPa (SYG) for 10h.
