A method for manufacturing bamboo redwood includes steps of selecting and
cutting off materials, and radially splitting a bamboo
barrel into 10 to 15 equal parts by a bamboo
cutting machine; removing bamboo green parts, bamboo yellow parts and bamboo joints by a bamboo slicer, and preparing bamboo chips in certain sizes;
grinding the bamboo chips, dividing the bamboo chips into threads, subjecting bamboo bundles to activating treatment: applying
dyeing adhesive; dipping the bamboo bundles in
dyeing phenolic
resin adhesive solution for 3 minutes to 5 minutes in a pressurization manner, manually paving dyed
adhesive-dipped bamboo bundles longitudinally to form a plate blank with a certain thickness; feeding the blank into a
hot press to realize solidifying and forming, and preparing a reconstructed bamboo plate; and finally splitting and sawing the bamboo plate according to needs, and
processing and using the bamboo plate. The
dyeing phenolic
resin adhesive solution contains from 20 to 40% of
solid. The
crystallinity of bamboo fibers and the specific surface areas of the bamboo bundles are reduced by means of pressurized activating treatment,
accessibility and leaching resistance of dye are improved, imitated redwood bamboo furniture and decorative materials are manufactured, and
additional values of reconstructed bamboo are increased by 40% at least under the condition that cost is seldom increased.
