Performance Analysis of Ammonium Lignosulfonate/Urea Formaldehyde-free Fiberboards

摘要：

The tests on physical and mechanical properties of fiberboards made of wood fiber with ammonium lignosulphonate/urea as filling material are performed according to requirement of EU standards EN 622-2-2004 Fibreboard-Specifications Part 2: Requirements for hardboard reveal the reaction mechanism of formaldehyde-free fiberboards with ammonium lignosulfonate /urea as filling material through analysis of characteristics of chemical reactions on ammonium lignosulfonate and urea by FTIR and the chemical reaction analysis of C atom by ESC A.The results show that physical and mechanical properties of fiberboards with ammonium lignosulphonate/urea as filling material have reached the requirement of EU standards EN 622-2-2004,the forming of furan resin,the results of reaction between urea and furfural substances is main reason for the better physical and mechanical properties of lignin-based formaldehyde-free fiberboard.
