Embodiment Construction

[0008] Take the production of 1cm thick board as an example: first put the tea seed shell into the cooking tank, add tap water to immerse the raw material, and directly introduce steam to make the raw material in the tank boil for 30 minutes, send it to the pulverizer and grind it to a gradation with a diameter of 0.1 to 1.5cm Uniform flaky particles, rinsed in the rinsing tank, decontaminated and drained, baked at 130°C without open flame for 10 minutes, sent the tea seed shells to the sizing mixing tank, and applied 10% tannin glue and 1% paraffin wax on the edge of the tank While stirring evenly, send it to the preforming machine, divide the thickness of the blank into 3 equal parts, and pave 2 sheets of synthetic fiber reinforced mesh with a grid size of 2 cm square and a mesh diameter of 0.3 mm at 1 / 3 and 2 / 3 of the blank, and place the paddle The material is flattened into a blank with a thickness of 3cm and a size of 1.2m×2.4m. It is made by hot pressing at 230°C with a ...

Description

Technical field: [0001] The invention relates to a building material, in particular to a tea seed shell plywood which can replace wood and protect cultivated land and a production method thereof. Background technique: [0002] With the progress of society, the improvement of people's living standards, and the vigorous development of the construction industry, the demand for wood and bricks is unprecedentedly strong. However, my country's forest resources (coverage rate is only 10.7%) and cultivated land are very limited (burning bricks consumes more than 100,000 mu per year). In order to protect the ecology, a plan to return farmland to forests has even been proposed. Therefore, we urgently need building materials that can replace wood and brick. Although there are many kinds of medium density plywood at present, its raw materials are mostly wood, wheat straw, cotton straw, sunflower straw, rice straw, etc. The shortage of wood will inevitably lead to high raw material cos...
