The invention belongs to the technical field of metal surface treatment, and specifically relates to a preparation method of a nanostructure layer of a zirconium-base amorphous alloy surface. According to the preparation method, a disc made of zirconium-base amorphous alloy is used as a working electrode, and a rotating disc electrode system is used for preparing the nanostructure layer on the zirconium-base amorphous alloy surface. According to the preparation method, the nanostructure layer can be formed on the zirconium-base amorphous alloy surface, the nanostructure layer is composed of aplurality of nanorods with the diameter between 10 and 30 nm, and uniform micropores are formed between the nanorods; when the zirconium-base amorphous alloy with the nanostructure layer is implantedin vivo, bone ingrowth is facilitated, and synostosis is formed together with target tissues; the rotating disc electrode system is used for preparing the nanostructure layer, and by-products and impurities can be thrown away from the surface of the disc during high-speed rotation of the rotating disc in the forming process of the nanostructure layer, so that adverse effects of the by-products andthe impurities on the nanostructure layer are avoided, and the uniform fine nanostructure layer is obtained.

The invention provides a novel EM microbial agent for manure composting, which is obtained by mixing beneficial microbial groups, organic matter biodegradation growth factors and heavy metal binding materials according to the mass ratio of 1-2:3-5:4-6 ; The beneficial microbial group is obtained by mixing photosynthetic bacteria, lactic acid bacteria, bacillus, saccharomyces, white rot fungi, actinomycetes, nitrogen-fixing bacteria, Trichoderma and nitrifying bacteria according to an equal mass ratio; the organic matter biodegradation growth rate factor It is composed of inorganic salt, cellulase synergistic protein, water-soluble sugar and organic acid, and the heavy metal binding material is bentonite molecular sieve or fly ash molecular sieve. The novel EM microbial agent of the invention can simultaneously solve the problems of odor pollution, heavy metal pollution and shortage of auxiliary materials in the feces composting process.

The invention relates to a composite, in particular to a PVC (polyvinyl chloride) biomass foaming composite and a preparation method thereof. The PVC biomass foaming composite is prepared from components of preparation raw materials in parts by weight as follows: 100 parts of PVC, 5-50 parts of PVC renewable materials, 5-30 parts of biomass powder, 50-130 parts of calcium sulfate, 5-12 parts of a stabilizer, 1-5 parts of a foaming agent, 2-18 parts of a foaming regulator, 0.6-3.5 parts of an internal lubricant, 0.6-3.5 parts of an external lubricant, 1.8-2.5 parts of a PVC processing aid and 0.6-2.5 parts of a coupling agent. By means of the formula, the filler content of a PVC foaming system can be increased by 20%-50%, the weight of the product per meter is basically unchanged, and the material has higher cost performance. With the adoption of technique principles of new materials, the PVC biomass foaming composite has creativity of new material application, has characteristics of resource utilization, energy conservation, environmental protection and green economy and is suitable for industrial production.
