Chipboard - with aminoplastic or phenoplastic bonding agent mixed with fine particles of vermiculite
摘要
<p>Comminuted wood chips are impregnated with a mixture of the aqueous bonding agent and fine particles of expanded mica (vermiculite) and then heat pressed to form the panels with improved rigidity and reduced swelling properties. Pref. the expanded mica has a granule size distribution of 0.0001-0.5 mm with an av. granule size of 0.01-0.1 mm.</p>
