The invention provides a high-efficiency extinguish material for a major fire source, which comprises the following components by weight portion: 1 to 50 portions of component A, 1 to 2 portions of component B, 2 to 1,000 portions of component C, and 0 to 200 portions of component D. The component A is an inorganic silicate material; the component B comprises a foaming agent, a surfactant and a dispersing agent; the component C is water; and the component D comprises a defoamer, a fireproof material, a material generating flame-retardant gas through pyrolysis, a water absorber, a colloidal material and a filling material. The high-efficiency extinguish material overcomes the defects that the prior art has high production and using cost, fast running-off, low service efficiency, severer pollution and high residual quantity, has the advantages of low cost, controllable specific gravity, higher viscosity, difficult seepage, loose storage conditions, fast production, convenient use, safe performance and the like, and can achieve large batches of long-distance transportation. The high-efficiency extinguish material is applicable for large-scale fire extinguishing of oil products, flammable chemicals, large buildings, coal mines, forests and the like, other fire source control and the like.

The invention relates to a method for the comprehensive application of fly ash or slag, in particular to a method for the predesilication of the fly ash or the slag. The method mainly comprises the process flows including the baking and the activation of the fly ash or the slag, the formula process of the raw meal of activated the fly ash or the slag and a sodium hydroxide solution and the production of white carbon black. Through adopting a technological line during which the fly ash or the slag are baked and activated at first and then a sodium hydroxide solution is used to extract noncrystalline silicon oxide at a low temperature, the method ensures that the mass ratio of aluminum oxide and silicon oxide of desilicated fly ash reaches to 2.14; therefore, the method breaks a new path totake the fly ash or the slag as a raw material source for extracting metallurgical-grade aluminum oxide, thereby increasing the comprehensive utilization value of the fly ash and the slag.

The invention discloses a method for producing a bark mixed medium-density fiber plate, which comprises the following steps of: dissolving natural cement in barks with acid solution; separating bark fibers in a mechanical high-speed rubbing separation manner, namely a normal-temperature mechanical process, under a drying condition of the temperature range of 5 to 30 DEG C; oven-drying the separated bark fibers; adding a wood fiber material into the oven-dried bark fibers and fully mixing and blending, wherein the bark fiber content after mixing is more than or equal to 40 percent; preparing amixed raw material from the bark fibers, the wood fiber material and glue by adopting a blast air glue injecting process when the raw materials are stirred and blended; and spreading the mixed raw material into a plate shape, molding and hot pressing to form plates. When the method is used for manufacturing the medium-density fiber plate, the resources of the production raw materials of the medium-density fiber plate are widened, and wastes are changed into valuable materials, so that the comprehensive utilization rate of forest resources is greatly improved and the manufacturing cost of the medium-density fiber plate is reduced.
