A supplement dispensing closure couplable to an outlet of a container, such as a water container. When the closure is coupled to the container, liquid exiting the container through the outlet flows through a supplement retention area that retains a dissolvable supplement body inside the closure as the liquid flows therethrough and dissolves the dissolvable supplement body. A user may select one or more dissolvable supplement bodies and insert them inside the supplement retention area for dissolution in the liquid as it flows through the supplement retention area. The closure may include a selectively openable and closable cap portion. Optionally, the closure includes a filter configured to filter one or more components from the liquid before or after it flows through the supplement retention area.

The invention discloses a slow-release fertilizer pot and a preparation and fertilizing method thereof. The method comprises that fertilizers, trace elements and the like which are required by plants are placed in the fertilizer pot, the fertilizer pot is buried at roots of the plants, and the fertilizers or trace elements penetrate out of the fertilizer pot or are attached to the fertilizer pot and are supplied for the roots of the plants. The problems that in tropical zones, leaching of nitrogen and potassium is rapid and immobilization of a phosphatic fertilizer is severe are solved, the method which uses the fertilizer pot formed by pressing of plant fibers for containing fertilizers is used for providing fertilizers for the roots of the plants stably in a long time, the utilization ratio of the fertilizers is above 40%, the fertilizer pot can be used for directive root cultivation of the plants and improvement of the soil environment, application effects of long-term plants and cash crops such as rubber trees and mangos are remarkable, and the fertilizing method is high-efficiency and environment-friendly.

The invention relates to a preparation method of Al-based Pb-WC-CeO2 inert composite anode material. The Al (aluminium alloy) -based Pb-WC-CeO2 inert composite anode material which is doped with micron tungsten carbide (WC) and nano ceric oxide particles is prepared by methods of chemical plating and composite plating. The anode material takes on gray black on the surface and has the plating thickness of 100-200mu m. Compared with the traditional lead and lead-based alloy anode, the composite anode material increases the surface roughness so as to enlarge the specific surface area, and improves the using efficiency of the anode; when being used for non-ferrous metal electrowinning, the electrode material reduces the bath voltage by 0.2-0.4V, improves the current efficiency by 1.5-2.5% and effectively reduces the power consumption; meanwhile, the anodic dissolution speed is slowed down by half, so that the pollution for cathode products caused by anodic lead dissolution is effectively reduced; and the invention is added with tungsten carbide particles with good electro-catalysis activity and electrical conductivity, thus not only guaranteeing the performance of material, but also improving the hardness and the wear resistance of an anode plate and enhancing the mechanical strength.

The invention discloses an antibacterial powder coating, prepared from the following raw materials by weight: 25 to 35 percent of epoxy resin, 25 to 35 percent of polyester resin, 0.8 to 1.5 percent of flatting agent, 0.8 to 1.5 percent of smooth degasifier, 0.3 to 1.5 percent of antibacterial agent and 25.5 to 48.1 percent of pigment and filler. A coating film formed after the antibacterial powder coating material is sprayed and cured has excellent antibacterial performance, and takes effect quickly in antibacterial capability, and the effect is long-acting and lasting.
