The composition and content of the high wear-resistant vacuum coating UV-curable coating are: 10-30wt% of difunctional urethane acrylate, 10-40wt% of high-functional urethane acrylate, 5-20wt% of high-functional acrylate monomer, single Functional acrylate monomer 0-15wt%, acid adhesion promotion 1-10wt%, photoinitiator 1-6wt%, nano wear-resistant material 0-5wt%, additive 0.1-2wt%, solvent 10-50wt%. The invention is aimed at protecting the surface of vacuum coating workpieces of electronic products such as mobile phones, MP3s, and digital cameras, and has the characteristics of good surface effect, super wear resistance, high temperature and high humidity resistance, cold and heat cycle resistance, and excellent yellowing resistance, among which RCA has the highest wear resistance It can reach more than 1500 times, effectively improving the service life of electronic products. The invention effectively solves the adhesive force and wear resistance of the UV-cured vacuum coating paint, solves the matching problem of the primer and top paint of the UV-cured vacuum coating paint, and has wide versatility.

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 discloses a special wear-resistant ball for phosphate rock, and its components include: C: 2.2-3.5%, Si: 0.3-1.2%, Mn: 0.5-1.5%, Cr: 8.0-11.0%, Mo: 0.2-2.0%, Ni: 0.2-1.5%, V: 0.1-1.5%, S≤0.06%, P≤0.06%, and the balance is Fe and unavoidable impurities.
