The invention belongs to the field of sweet potato storage, and particularly relates to a method for storing sweet potatoes through charcoal functions. The sweet potatoes and wood charcoal / bamboo charcoal are stored mixedly under an air composition environment where the temperature ranges from 1 DEG C to 26 DEG C and the humidity is natural, at least six kilograms of the wood charcoal / bamboo charcoal are allocated to one hundred kilograms of the sweet potatoes, and the distance between the sweet potatoes and the charcoal is smaller than 30 centimeters. The method is used for storing the sweet potatoes, and therefore the sweet potatoes can be stored for more than eight months and have no disease or decay phenomena; in the storage process, neither chemical sterilization disinfectant nor preservative is needed, and special sheds, pits and temperature and humidity regulation facilities are not needed. The wood charcoal for storage can be repeatedly used, storage cost is reduced, and meanwhile the requirement for the environment of sweet potato storage is greatly reduced. The storage process is simplified, the problem that it is difficult to store the sweet potatoes for a long time is solved, and the method is convenient to popularize and makes a great contribution to protection of potential grain strategy safety of our country.

The invention relates to a conductive polymer microcapsule of a reactive liquid core material and a preparation method thereof, belonging to the technical field of preparation of functional materials. The preparation method is as follows: configure an aqueous solution containing surfactant at room temperature, heat it to 30-60°C, add a reactive liquid core material 0.05-0.25 times its mass, and stir at a speed of 200-2000rpm for 10-30min, then Reduce the stirring speed to 50-200rpm and continue for 30-120min. After natural cooling, the product is washed with deionized water to obtain a suspension; add an aqueous solution of an acidic oxidant or an aqueous solution of a heteroaromatic ring monomer that is 1 to 5 times the mass of the core material to the suspension , after reacting for 5 to 20 minutes at room temperature and under mechanical stirring at 100 to 300 rpm, add 5 to 20 times at intervals of 2 to 20 minutes and add heteroaromatic ring monomers whose total amount is equivalent to 1 to 5 times the mass of the core material The aqueous solution or the acidic oxidant aqueous solution is polymerized for 1-12 hours, and finally washed with deionized water and dried, and the aqueous solution added for the first time in this step is not the same substance as the aqueous solution added later. The method of the invention is simple, the raw material is cheap, and the product is easy to collect.

The invention relates to the field of coating of aluminum alloy tank cars, in particular to a coating method for maintaining the original color of aluminum alloy tank cars. The coating method for maintaining the original color of the aluminum alloy tank car comprises the following steps: step 1, pre-painting treatment; step 2, repairing the appearance defects of the aluminum alloy base; and step 3, coating varnish. The coating method for maintaining the original color of the aluminum alloy tank car provided by the invention can not only repair the appearance defects such as scratches, scratches, blackening and corrosion on the surface of the aluminum alloy, but also make the aluminum alloy tank body and the aluminum alloy tank body of the aluminum alloy tank car The parts maintain the original unique metallic color.
