The invention has the advantages that the modification of the equipment of the wood particle board and the three screenings ensure the rationality of the shape of the stalk stalk material, and the plant straw stalk plate is manufactured under the condition of high utilization rate of the raw material, the plant The main physical and mechanical properties of the straw stem board meet the requirements of wood fiberboard. The present invention specifically has the following practical embodiments: Example 1 Preparation of the stalk material, the straw stalk 500 kg, 7 cut the straw stem into 31 straw straw units, and screen to remove broken leaves, mud sand, etc. Impurities: 2 The straw unit after the division is crushed by the crusher; 3 The broken straw stems are mechanically screened, which are respectively 8 mesh, 2 mesh, 100 mesh screens to separate the coarse , fine material two trough, its "mesh<rough material dim, 2 &目< fine material <100 mesh; 4 will be larger than " stalk shards back to step 2. Take coarse and fine straw stems (10) 200808509 Dry with a rotor dryer, the drying temperature is 100 °c, so that the water content of straw residue is up to 4%. In order to ensure the product has a fine surface, it is necessary to make the raw materials quantitative. The fine material, the surface layer fine material and the core layer coarse material are different in the amount of glue used. Therefore, it is necessary to separate the core and the core layer after drying. The rotary screen is used for sorting, so that the fine material is fed into the surface silo, and the coarse material enters the core silo. 5公斤的防水剂。 The use of the isocyanate (MDI) as a binder, wherein the amount of sizing is 6 kg, and the amount of sizing of the core layer is 4. 5 kg, adding 0.5 kg of water-repellent agent. • The glue is done in a ring mixer. In order to ensure uniform sizing, it should be ensured that the ratio of the consumption of the adhesive to the straw stalk is a constant constant, so that the moisture content of the raw material of the slag is 8%, and the existing stalk of the straw stalk is mixed with the existing airflow. Paving machine paving, due to the low density of straw stalks, the uniformity of the density of the slab must be controlled. The slab thickness after paving is 10 cm. After pre-pressing, the thickness of the slab is reduced, but the quality of the slab is improved and the damage during transportation is also avoided. The hot press is a single-layer hot press, and the release agent is used before the hot pressing to prevent the adhesive sheet. 5Mpa。 The hot pressing pressure is 0.5 ° / leg, hot pressing pressure is 2. 5Mpa. The finished sheet is cooled at room temperature. The purpose of cooling is to lower the temperature of the sheet, eliminate stress in the sheet, and prevent deformation of the sheet. After cooling, trimming, the size of the web is 1220 mmx2440 legs, standard panel specifications, sanding after 48 hours of stacking. Example 2 Preparation of straw stalk material, weighing 500 kg, 7 straw stems into 50-leg straw unit, screening and removing impurities such as broken leaves and mud sand; 2 straw unit after screening was crushed by crusher ; 3 broken straw 200808509 stalk material and mechanical screening, β 呷 &, respectively, 8 mesh, 20 mesh, 1 〇〇 之 之 , , , , , , , , , , , , , , , , , , , , , , , , 8 mesh <rough material < : material return two fine materials < 1 〇 ° mesh; 4 will be greater than 8 mesh straw stalks] dry welding U. 100 kg of coarse and fine straw stalks are transferred to 0 horses to ensure that the product has a delicate surface. It must be 3 materials: there are quantitative fine materials, surface fine materials and core layer coarse materials. The same. Therefore, it is necessary to separate the core and the core layer after drying. The rotary screen is used for sorting, so that the fine material is fed into the surface silo, and the coarse material enters the core silo. Use isocyanate (4) (MDIj adhesive, in which the surface layer is 5 施, and the core layer is 5 kg in sizing, 丨 kg of water repellent should be added when sizing. Sizing is in % mix Completed in the machine. In order to ensure uniform sizing, it should be ensured that the ratio of the consumption of the adhesive to the straw stalk is a constant constant, so that the moisture content of the raw material mixed with f is 16%, and the straw of the mixed stalk is broken. The material is paved with the existing airflow paving machine. Due to the low density of straw stalks, the uniformity of the slab density must be controlled. The thickness of the slab after paving is 13 cm. After pre-pressing, the thickness of the slab will be reduced. However, the quality of the slab is improved, and the damage during transportation is also avoided. The hot pressing adopts a multi-layer type hot press, and the release agent is used before the hot pressing to prevent the adhesive sheet. The hot pressing temperature is 170 C, hot pressing The time is 〇·gmin/dirty, and the hot pressing pressure is 3Mpa. The plate after the hot pressing is cooled at normal temperature, the purpose of cooling is to lower the temperature of the plate, eliminate the stress inside the plate, and prevent the deformation of the plate. After cooling, trimming, format The size is 1220 丽 x 2440 draw 1, the standard board specifications, pile up i 50 hours later Sanding. In summary, the present invention is indeed a novel and progressive creation, and the same or similar products are not publicly used in the technical field of the same phase. The invention has met the requirements of the invention patent, and is applied according to law. Pray that the invention patent will be granted as early as possible. 200808509 [Simple description of the diagram] No [Main component symbol description]
