Problems solved by technology

Because the flue is in a high-temperature working environment all the year round, the oil fume gasifies to form oil deposits, carbon deposits or greasy jelly. These three substances are very easy to cause fires. Low fire resistance, not insect-proof and moth-proof, has become a subject that has been puzzling people's research

Embodiment 1

[0015] The batching process in the production process is divided into three processes: processing rice and wheat straw, preparing brine and preparing modifiers.

[0016] (1) Process rice and wheat straw first, and the preparation of rice and wheat straw scraps is a very critical process in the process of manufacturing flue board materials, which is directly related to the performance of flue board materials. Therefore, artificial selection of straw requires that the selected plant straw have a water content of no more than 20% and have no mildew. It is crushed by a pulverizer, and the crushed straw is filtered through a 50-mesh sieve until there are no large pieces of straw. Stop sieving after there are no impurities.

[0017] (2) Prepare brine again. The preparation method of brine is to put magnesium chloride in an acid and alkali resistant container, press MgCl 2 :H 2 O=(85~100): 100, add water and stir. When stirring, the magnesium chloride should be completely dissolved...

Embodiment 2

[0020] The curing of the flue plate material is a special magnesite cement formed by the chemical reaction of magnesium oxide and magnesium chloride solution, and a hydraulic substance is formed to complete the hydration reaction to achieve hardening. The hydration and hardening process is A significant exothermic process, the exothermic heat can reach more than 100°C in summer, and the internal temperature rise should not exceed 60°C during the curing process. Generally, the molding temperature should be controlled at 30-40°C. Due to the exothermic heat preservation measures cannot be taken, otherwise it will If hardening strength is destroyed, if you want to form quickly in winter, the temperature of the drying room can be moderately heated to about 20°C.

Embodiment 3

[0022]For maintenance, after the board is formed and demoulded, the product should be moisturized and maintained. The products can be stacked together, sealed with plastic cloth, and the temperature and humidity of the environment can be maintained by using its own hydration heat and dehumidification. Yes, the strength after 7 days can reach 85-95% of the predetermined strength; then carry out the moisture-proof treatment of the formed board, put the board that has been demolded and cured into an aqueous solution with 0.2% oxalic acid and 0.2 h phosphoric acid and soak for 12-15 n , and then place the product in a dry air for drying, and then cut the edges after drying.

Abstract

The invention provides a producing and processing method for flue sheet material prepared by mixing straws, and relates to flue sheet material for floor. The flue sheet material has the advantages of resisting fire and flaming, resisting moisture and mildew, and resisting insects and moth, and is good in waterproof property and high-temperature-resistant, is capable of being sawed and planed, is endurable, simple in production process, safe and convenient to operate, and high in production efficiency, thus being novel flue sheet material. Straws of rice and wheat are utilized as main raw material of the flue sheet, thus reducing pollution of burning the straws of rice and wheat to the environment, being low in cost, changing wastes into valuables, being high in additional value, lowering the manufacturing cost of the flue sheet, protecting the ecological environment, benefiting the country and people, and making contributions for creating economic and low-carbon society for China.

Description

technical field [0001] The invention relates to a floor flue board material, in particular to a production and processing method for the flue board material made by mixing straw. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's industrial development. my country's industry is gradually developing in the direction of conservation, energy saving, emission reduction, and low carbon. Due to the rapid development of economic construction, my country's demand for timber has been increasing in recent years. The annual indiscriminate logging has caused a shortage of forest resources, waste of resources, a large amount of soil erosion, land desertification, and environmental and ecological balance. Our country is facing the problem of relative shortage of forest resources. my country is a large agricultural cou...
