<p>A process for manufacturing a press moulding plate with good constructional strength, which includes the steps of mixing the waste scrap materials of long fibre plant such as rice husk, rice stalk, bagasse, hemp stalk and the like having high ignition point and nonhygroscopic properties with urea, trichloro-cyanamide as well as resin, mixing the mixture obtained with a salt(NaC1) in a certain ratio and heating the resultant to form the basic material, putting the bamboo sheet or network sandwich weaved rattan between the upper and lower basic materials, forming the plate after pressurization and solidification. Thus the product obtained has the advantage that not only protecting environment due to utilizing the waste plant as raw stuff but also replacing wood owing to the good constructional strength and high ignition point (fire prevention), thermal insulation, nonhygroscopic, sound insulation, insect-proof properties, so as to accord the practical requirement.</p> |
