The invention relates to a merchandise anti-counterfeiting verification system based on natural biological information, and the system comprises an anti-counterfeiting information generation module which is user for generating unique anti-counterfeiting information corresponding to merchandise, an anti-counterfeiting database which is used for saving the unique anti-counterfeiting information generated by the anti-counterfeiting information generation module, and an anti-counterfeiting information verification module which is used for performing anti-counterfeiting verification on merchandise based on the unique anti-counterfeiting information saved by the anti-counterfeiting database; the anti-counterfeiting information generation module comprises: an identity information generator which is used for generating unique identity information corresponding to the merchandise, a natural biological information generating component which is used for generating natural biological information corresponding to the merchandise, and an information binder which is used for binding and packaging the unique anti-counterfeiting information and the natural biological information. Compared with the prior art, the system has advantages of simple realization, good anti-counterfeiting performance, cost saving and the like.

The invention relates to a carbon-coated white carbon black. The carbon-coated white carbon black is prepared through the following steps: modifying the white carbon black by using starch, oligosaccharide, glycerinum and polyethylene glycol as raw materials, evenly coating silicon dioxide with a carbon layer, and carbonizing at a high temperature in an insert gas or anaerobic atmosphere to obtain a core-shell structure nano-powder with silicon dioxide as a core and carbon as a shell. Compared with the traditional white carbon black, the carbon-coated white carbon black is covered with a unique carbon coating layer so that the white carbon black has electric conductivity, the structural property of the white carbon black is improved and the compatibility of the white carbon black with rubber is improved, and when the carbon-coated white carbon black is applied to a tire, the tire has the characteristics of improved slippery resistance, low generation of heat by friction and the like. The new material carbon-coated white carbon black has the advantages of simple preparation process and use of simple and easily available raw materials; the prepared carbon-coated white carbon black has excellent properties, meets various performance indexes of the white carbon black for rubber, and thus has good economic benefit.

The invention discloses an electrophoretic aluminum alloy building proximate matter with high performance and a preparation method thereof, and belongs to the technical field of aluminum alloy application. The electrophoretic aluminum alloy building proximate matter consists of following ingredients by mass: 0.5 to 0.54 percent of Mg, 0.4 to 0.44 percent of Si, 0.04 to 0.08 percent of RE, 0.01 to0.02 percent of Ti, 0.002 to 0.004 percent of B, 0 to 0.2 percent of Fe and remaining aluminum. The preparation method of the electrophoretic aluminum alloy building proximate matter consists of following steps: a misch metal ingot, an alloy of Al, Ti and B, and a pure aluminum ingot are smelted into a refining and modifying agent of RE, Al, Ti and B; the refining and modifying agent is added during an alloy smelting process and cast into an aluminum rod; the electrophoretic proximate matter with high performance is prepared by techniques of squeeze aging and oxidizing electrophoresis, etc. Byutilizing rare earth to subdivide second-phase particles, electrophoretic paint films of the proximate matter that are obtained by improving surface processing performance have higher uniformity, adhesive attraction, wear resistance, corrosion resistance and large film thickness than common proximate matters, and can be widely used for aluminum alloy doors and windows of buildings and curtain walls.
