TH22173A - "High-strength pressed bamboo and a process for producing the same" - Google Patents

Abstract

This invention involves high strength pressed bamboo. Especially related to Compressed bamboo is used for containers and a process for manufacturing the same. This pressed bamboo will include The surface plate and the bottom plate, which is a single layer of thin bamboo sheet, is made up of the Uniform width and thickness The same goes for the nets that are made up of at least a thin layer of bamboo. Two discs, which are directly overlapped. The sides that touch each other of such a thin layer of bamboo It is coated with a waterproof resin that is mixed with a compound used to treat and protect the wood surface. The surface of the substrate and the bottom plate is then coated with a phenolic aldehyde coating. Or a coating for plastic Glass fiber trim as well The pressed bamboo is made by cutting the raw material bamboo into pieces. And then will operate for It is a thin bamboo plate that is uniform in width and thickness. To fix the thin planes that are fixed side by side. All along to make a single layer of bamboo To dry this thin sheet to 12 to 18% water, the resin coating is then dried to 12% the water. The extrusion of the thin plates and the heat compression operation at temperatures of 140 to 170 degrees centigrade under a pressure of 20 to 40 kg / cm2. The compressed bamboo provided by this invention will The advantages are the advantages Lower production costs, high utilization rate of raw materials, little difference between mechanical operations according to Longitudinal and lateral processes are highly automated, stable quality and will meet the requirements by International standards for container floors
