The invention relates to a rice husk pyrolysis electric power generating and comprehensive utilization method, and belongs to the field of biomass energy chemistry. The method comprises following steps: 1, biomass pyrolysis generation of pyrolysis gas and pyrolytic carbon; 2, synchronous oxygen removing, tar reduction, and phenol enrichment; 3, pyrolysis gas heat exchange cooling heat recycling, and separation of phenol containing waste water; 4, electrostatic tar capturing pyrolysis gas purifying, and tar enrichment; 5, pyrolytic carbon is adopted for dispersion of tar, synchronous water gasreaction, and steam reforming production of hydrogen-enriched gas; 6, reaction waste residue is taken as a biomass nanometer silica preparation raw material; and 7, preparation of phenolic resin adhesive from the phenol containing waste water. According to the method, hydrogen in water is adopted to solving problems of using of biomass as an energy that hydrogen content is low and oxygen content is high; pyrolysis and steam reforming two step method is adopted to prepare hydrogen-enriched high-energy combustion gas, electric power generation and heat supply are realized; at the same time, thephenol containing waste water is enriched to produce biomass phenol base adhesive, so that environment pollution caused by chemical phenol is reduced, cost is reduced, waste is changed into valuables;by-product natural nanometer silica is obtained, and an ultra wear resistance material is provided for green aviation tyres.

The invention belongs to the technical field of coatings, in particular to a novel inorganic super abrasion-resistant, fireproof and flame-retardant mineral floor coating. The novel inorganic super abrasion-resistant, fireproof and flame-retardant mineral floor coating is prepared from the following raw materials in percentage by mass: 1 to 10% of dispersant, 0 to 5% of cellulose, 0 to 5% of bentonite, 0 to 3% of defoaming agent, 0 to 5% of flatting agent, 0 to 4% of wetting agent, 1 to 15% of titanium dioxide powder, 0 to 15% of aluminum hydroxide, 0 to 10% of wollastonite powder, 15 to 30% of silicon dioxide, 0 to 5% of fused silicon dioxide, 0 to 40% of nanometer silicate, 0 to 5% of thickener, and the balance of water. The novel inorganic super abrasion-resistant, fireproof and flame-retardant mineral floor coating has the advantage that the mineral (silicate) is used as a filming matter, so that the characteristics of the traditional floor coating are realized, and the super abrasion-resistant, fireproof and flame-retardant characteristics are also realized.

The invention belongs to the technical field of ceramics, and discloses giant crystal particles capable of forming crystal flowers, a combination of dry particles, particles for ceramics, ceramics and a preparation method for ceramics. The chemical quality composition of macrocrystalline grains includes SiO 2 、Al 2 o 3 、K 2 O, Na 2 O, CaO, MgO, BaO, ZnO, F, Li 2 O, TiO 2 , and metal oxides for coloring.
