ALDEHYDE (ALDEHYDES) CAPTURE MATERIAL AND PROCESS FOR PRODUCTION OF PLYWOOD WITH THE SAME

摘要

[PROBLEMS] To provide an aldehyde capture material to be used in producing plywood by using veneers and a formaldehyde adhesive, which is not lowered in the capturing power even when the resulting plywood is subjected to surface grinding and which exerts a high capturing power for formaldehyde; a process for the production of plywood with the material; and plywood obtained by the process. [MEANS FOR SOLVING PROBLEMS] A powdery aldehyde capture material containing at least one aldehyde-capturing compound which is solid at ordinary temperatures and has the property of generating an acid gas such as sulfurous acid gas on being heated; and a process for production of plywood which comprises incorporating the above aldehyde capture material into an adhesive or veneers and producing plywood through hot pressing by the use of the adhesive and the veneers.
