TH140356A - The process of producing veneer from durian bark fibers using a binder extracted from durian bark. - Google Patents

Abstract

DC60 (12/11/56). This invention revealed a process. Production of veneer from durian bark fibers This invention contains Its structure consists of durian bark fibers and durian bark powder. With the following steps Start with Fresh durian peel was dried by a drying oven at 80 degrees Celsius for 8 hours, then crushed and screened with durian peel powder with size above 60-100 mesh, the durian peel adhesive powder was obtained for production. The pressed wood sheet, which is a glue powder from durian bark that has never been invented before, is a replacement for the synthetic glue used in industry and the fibers from the durian bark size not higher than 60 mesh are made into fibers for the production of wood pieces. Pressed by fibers mixed with durian peel glue powder and water. At the mixing ratio Durian peel powder per durian peel fiber per water equal to 11: 1, then the mixture that has been mixed and form the sheet. By sprinkling it into the mold and then pressing it at 1000 Psi pressure for 1 minute, pressure 900-1000 Psi for 4-5 minutes and pressure at 1400-1500 Psi for 1 hour. The veneer from the produced durian husk can be used for 24 hours at 80 ° C. Various substitutes for natural wood This invention has revealed a method The process of veneer production from durian bark is as follows: starting from fresh durian peel to dry with a hot air dryer at 80 ° C for 8 hours, then crushed by a hammer mill. The durian peel powder with a size higher than 60-100 mesh will then be obtained from the durian shell adhesive powder to produce the sheets. Shell plywood Durian that has never been invented before. And the fibers from the durian peel that have been mashed With a hammer mill, sieve with (Sieve Machine), fibers with a size of not less than 60 mesh are made into fibers for the production of plywood sheets. By drying durian peel fibers With a drying oven (Oven) and fiber mixed with glue powder from durian peel and water. The fibers from the durian bark, not higher than 60 mesh were used to mix the glue powder from the shell of the water tank. The plywood production ratio was produced at the ratio of durian bark powder to durian bark fiber per water ratio of 1: 1: 1. That have been mashed together Comes through a fiber carding process Using a device capable of separating fibers or a pulp grinder After that, the sheet was formed. By sprinkling on a plastic sheet that is resistant to high heat by placing on a stainless sheet Thickness is controlled from size to thickness of mold. To get the desired thickness And when sprinkling the weight per 1 sheet, then heat it with 3 steps of pressure, using 1 hour - 1 hour and 15 minutes compression at 10 Psi pressure for 1 minute, pressure 900-1000 Psi for 4. -5 minutes and pressure at 1400-1500 Psi for 1 hour. Total for 1 hour - 1 hour 15 minutes. Bake the produced plywood sheets at 100 ° C for 24 hours and take the plywood sheets obtained. Adjust the conditions at room temperature for 1 week. Adhesive powder extracted from durian peel that has never been Invented before, it is used as an adhesive or a bonding agent in the production of durian husk veneer, consisting of durian husk fibers and water. That can be used as a veneer. Another option to increase the value of durian peel and reduce the problem of durian shell waste disposal, which is a waste material In agriculture, reduce environmental problems from the use of formaldehyde adhesives And generate income for the community (3E, Environment, Energy, and Economic) and lead the country to self-reliance by using Natural resources suitable for Thailand:
