The invention relates to a method for preparing textured potassium niobate sodium-based leadless piezoelectric ceramic and belongs to the field of preparation of leadless piezoelectric ceramic. The method comprises the following steps of: preparing power and obtaining slurry by taking flaky NaNbO3 or flaky KnbO3 as a template or a non-type template and selecting powder of Na2CO3, K2CO3, Li2CO3, Nb2O5, Ta2O5, Sb2O3 according to a chemical formula, namely, [(KmNa1-m)1-xLix](Nb1-y-zTaySbz)O33; laminating and pressing a plurality layers of thick ceramic films obtained by screen printing so as to obtain a biscuit; removing plastic from the biscuit; and sintering the biscuit from which the plastic is removed. A printing process is simple, the textured potassium niobate sodium-based leadless piezoelectric ceramic with a very high degree of orientation can be obtained and the highest degree of orientation factor is up to 90 percent.

Disclosed is a method for flax seeds decortication and separation, comprising dehydrading flax seeds to a moisture percentage of 2-4%; feeding same into a rotary centrifugal decortication machine continuously, decorticating the flax seeds to form a mixture of shells and kernels; and separating the shells and kernels mixture through an electrostatic field. An apparatus realizing said method comprises a centrifugal decortication machine, screen means mounted on the discharge side of the centrifugal decortication machine, a convey belt mounted on the discharge side of the screen, and electrostatic absorption means mounted over the discharge terminal of the convey belt front part. The method is provided with continuously industrialization production for large amounts of product, complete seperation of shells and kernels, and high production efficiency to shorten the art time from the flax seeds feeding, decorticating to discharging by 80%, decrease full cost by 50%, and produce no environmental waste materials.

The invention is applicable to the technical field of graphite composite materials, and provides a thermally conductive graphite composite material and a preparation method thereof. The preparation method of the thermally conductive graphite composite material includes the following steps: mixing flake graphite and aluminum powder, and then infiltrating with the interface agent to obtain a mixed powder; mix the binder with a solvent, and then mix with the above mixed powder to obtain a slurry; print the above slurry on the substrate by screen printing and dry it processing to obtain a thick film; after the thick film is formed and processed, organic matter removal treatment and cold isostatic pressing are performed to obtain a green body; the green body is subjected to discharge plasma sintering to obtain the heat-conducting graphite composite material. The thermally conductive graphite composite material prepared by the preparation method has obvious high orientation arrangement, and its orientation degree is high, so that high thermal conductivity can be realized on the xy plane.

The invention relates to a method for solidifying chromium in polluted acid slag. Its characteristic is that it includes the following steps: first, add modified metal magnesium slag to the dirty acid slag after drying and grinding, mix it evenly, and press it into a block, and then put the obtained block into a sintering furnace at 800-1300°C Keep it warm for 4‑8 hours, cool down, take it out and dry grind it into powder. The method of the present invention has the following advantages: the present invention is an environmentally friendly treatment method for solidifying and stabilizing the heavy metal Cr in the polluted acid slag. The modified reducing slag smelted with metal magnesium is sintered to realize the solidification and stabilization of the heavy metal in the polluted acid slag. The purpose of treating waste. Therefore, the solidification and stabilization process does not need expensive materials, and the cost of raw materials is low; the modified magnesium slag is fully utilized; the solidification process of the polluted acid slag is simple and easy to implement, so it can realize industrial operation; no secondary waste residue is produced in the process of solidifying and stabilizing heavy metals , Waste water.

The invention discloses a method for preparing seasoning instant osmunda japonica thumb. The method comprises the following steps of: S1, washing fresh osmunda japonica thumb, blanching, cooling to room temperature and salting; S2, elutriating the salted osmunda japonica thumb, draining water, adding white granulated sugar, filling in a fermenting tank, inoculating a complex microbial inoculant, and fermenting; and S3, removing part of salinity of the fermented osmunda japonica thumb, seasoning, vacuum packaging and bagging by adopting an aluminum foil compound pocket, and sterilizing. The method has the beneficial effects that alcoholic fermentation is carried out by utilizing acid-resisting yeast and taking sugar as a culture medium, obvious and faint soy sauce flavor is generated by virtue of common effects of saccharomycetes and lactic acid bacteria, thus unique taste and flavor of the instant osmunda japonica thumb are obtained, and the nutritive value of the instant osmunda japonica thumb is improved; the complex microbial inoculant can reduce the pH of the environment, inhibit growth of harmful microbes, and also has the capacity of degrading nitrite so as to guarantee the edible safety of the product; the fermentation period is greatly shortened, the yield is increased, and the agriculture efficiency and income of farmers are increased; and the method is simple, the technology is mature, the method is easy to popularize, and industrial production is realized.

The invention discloses a preparation method of a reversible hydrogen bond self-healing polymer. The preparation method comprises the following steps: (1) at room temperature, adding diisocyanate, a catalyst and a polymerization inhibitor into a reaction flask, dropwise adding hydroxy-terminated acrylate in a stirring state, then heating up to 40-50 DEG C, and stirring for reacting until the measured NCO value is half of the NCO value when reaction is started, so that a semi-terminated isocyante monomer is obtained; and (2) maintaining the temperature of the reaction system, replenishing the catalyst and the polymerization inhibitor into the reaction flask in the step (1), adding metered urea in batches in a stirring state, after the catalyst and the polymerization inhibitor are completely added, heating up to 60-70 DEG C, and stirring for reacting until the measured NCO value reaches a theoretical value, so that the reversible hydrogen bond self-healing polymer is obtained. The preparation method disclosed by the invention has the advantages that the operation is simple, the production cost is low, reaction conditions are mild, industrial production can be realized, and the obtained polymer contains a large number of N-H and C=O and has a self-healing capability.
