TH17363U - A formula for particle board with reduced swelling, derived from cassava stems, and the manufacturing process. - Google Patents

Abstract

------December 27, 2019------(OCR) Page 1 of 1. Summary of the Invention: A composite formulation of particleboard that reduces swelling, made from cassava stems, consists of finely ground cassava stems, latex glue, urea formaldehyde glue, boric acid, and sumifloc glue. The manufacturing process includes grinding the cassava stems, mixing the components, molding, and heat curing the particleboard. The cassava-based particleboard exhibits beautiful and unique grain patterns. The fine grinding of the cassava stems before molding results in a particleboard with high strength, durability, and reduced swelling. It can be used as a wood substitute for picture frames, clocks, furniture, ceiling panels, and interior decorations, thereby increasing product value and improving the quality of life for farmers. ------------ Page 1 of 1. Summary of the Invention: Strong and Non-Swelling Partitionboard from Cassava Stems. The production process involves shredding cassava stalks, mixing the cassava stalk mixture, compression molding, and heat curing of the particleboard. Cassava plywood has a beautiful and unique particleboard pattern. The cassava stalks are finely ground before compression and molding to produce plywood with high strength, durability, and reduced swelling. This wood substitute is used in picture frames, clocks, furniture, plywood ceilings, and interior decorations, adding value to the product and improving the quality of life for farmers.

Claims (3)

------December 27, 2019------(OCR) Page 1 of 1 page. Claims 1. A formulation of cassava-derived reduced swelling particleboard which consists of: - Crushed cassava stems 62.50% by weight - Latex glue 9.40% by weight - Urea formaldehyde glue 15.60% by weight - Boric acid 6.25% by weight - Sumifloc glue 6.25% by weight 2. A formulation of cassava-derived reduced swelling particleboard according to Claim 1 where the crushed cassava stems can be selected from the stalks, leaves, branches, or rhizomes of cassava, individually or in combination. 3. A process for manufacturing cassava-derived reduced swelling particleboard. The process for producing particleboard containing the components of claim 1 or 2 is as follows: A. Cassava stems are ground into smaller pieces using a coarse shredder, allowing a sieve to pass through a 0.2 mm mesh size, resulting in particle sizes of 0.1 - 0.3 mm. The resulting particleboard is then weighed. B. The ground cassava stem pieces from step A are mixed with a binder consisting of latex glue, urea formaldehyde glue, boric acid, and Sumiflox glue, according to the formula for producing particleboard that reduces swelling from cassava stems. C. Mix until homogeneous. D. Mold using a heat compress machine. Take the finely crushed cassava pieces mixed with the binder prepared in step B and pour them into a mold measuring 20 cm wide, 20 cm long, and 6 mm thick. Spread the cassava mixture evenly until the mold is full. Then place a stainless steel plate and a compression plate on top of the mold. E. Cure the prepared plywood pieces in the mold (from step C) in the heat compress machine at 100 degrees Celsius for 2 minutes. Then place the mold in the cooling channel of the machine for 2 minutes, and then remove the workpiece from the mold. ------------ Page 1 of 1 page. Claims 1. Formula for reduced swelling particleboard made from cassava stem, consisting of: - Crushed cassava stem 62.50% by weight - Latex glue 9.40% by weight - Urea formaldehyde glue 15.60% by weight - Boric acid 6.25% by weight - Sumifloc glue 6.25% by weight 2. The process for producing low-swelling particleboard from cassava stems, as per claim 1, involves the following steps: a. Cassava stems are ground into smaller pieces using a coarse shredder, allowing a sieve size of 0.2 mm to pass through, resulting in a particle size of 0.1 - 0.3 mm. The ground cassava stems are then weighed. b. The ground cassava stem pieces from step a are mixed with a binder consisting of latex glue, urea formaldehyde glue, boric acid, and Sumiflox glue, according to the formula for low-swelling particleboard from cassava stems. The mixture is then blended until homogeneous. c. The mixture is then molded using a heat compress machine. The ground cassava stem pieces mixed with the binder from step b are poured into a mold with dimensions of 20 cm wide, 20 cm long, and 6 mm thick. The mixture is then smoothed evenly to fill the mold. Next, place the stainless steel plate and the compression plate on top of the mold. Then, cure the prepared particle board in the mold (as described in step C) in a hot press at 100 degrees Celsius for 2 minutes. After that, place the mold in the cooling channel of the machine for 2 minutes, and then remove the particle from the mold. 3. The formula for reduced swelling of particleboard made from cassava stems and the manufacturing process as per claim 1 or 2, where the cassava stems to be ground can be selected from the stems, leaves, stalks, and rhizomes of cassava, either individually or in combination.
