The invention relates to a vitamin C smicrocapsule flour improver and a preparation method thereof. The wall material of the flour improver is a mixed type wall material containing starch, stearic acid monoglyceride and hardened oil, and the bag core substance is vitamin C. The stearic acid monoglyceride and the hardened oil are mixed and then melted, then the starch and the vitamin C are added in the molten mass and evenly stirred to obtain the finished product by freezing, granulating and crushing. The smicrocapsule flour improver has the advantages of good stability, proper release rate, security, no foreign flavor and high utilization ratio of the vitamin C. In the method for preparing the vitamin C smicrocapsule flour improver, the realized cladding rate is up to 90 percent, no solvent is required to be used, the environmental pollution phenomenon does not exist, the process is simple and feasible and the cost is low.

The invention discloses a boron carbide / silicon carbide ceramic hollow microsphere and a preparation method thereof. The preparation method utilizes a vinyl silane coupling agent to modify boron carbide, and then grafts PCS to B 4 on C‑V, then B 4 C-PCS is prepared into a slurry, and the polymer ball is used as a template to prepare a slurry coating ball, and finally the slurry on the polymer ball is cured in an air atmosphere, and then heat-treated in an air atmosphere to remove polymerization. Object spherical template, and finally fired at high temperature in an inert atmosphere to obtain boron carbide / silicon carbide ceramic hollow microspheres. The preparation method provided by the present invention can adjust the diameter of boron carbide / silicon carbide ceramic hollow microspheres by selecting polymer spheres with different diameters, and realize a wide range of diameter control, and the wall thickness of ceramic hollow microspheres can be changed by changing the slurry coating. The thickness of the wall can be adjusted in a wide range by adjusting the number of coating times. The preparation method is simple, convenient, fast and efficient, and the raw materials are cheap and easy to obtain, which has the potential for industrial production.

The invention discloses a completely recoverable barrier PE (polyethylene) membrane material, which comprises three or more than five layers of mutually overlapped membrane layer structures, the base material of each membrane layer is a PE material, and the membrane layer structure at least comprises one HDPE (high-density polyethylene) functional layer taking a high-density polyethylene polymer material as a base material. The preparation method of the membrane material comprises the following steps: feeding, heating and melting, co-extruding, blowing, cooling and shaping, drawing, rolling and the like. In the film blowing cooling shaping stage, all film layers are obtained through one-time film blowing forming, and a film material stretching and extending operation is additionally carried out in the traction process; the number of the extruders is more than five, and the number of the extruders is correspondingly consistent with the number of layers of a membrane material to be prepared; the number of the runners in the die head of the film blowing machine is more than five, and the number of the runners is consistent with the number of layers of a film material to be prepared. The membrane material can be applied to packaging materials or buffer bag materials for various industries.

The invention discloses a hot runner mold. The hot runner mold comprises a runner plate structure and a spray nozzle structure. The runner plate structure is provided with a surface melt runner and a core layer melt runner. A base comprises an outer surface layer melt passageway, a core layer melt passageway and an inner surface layer melt passageway. Surface layer melt enters the surface layer melt passageway and then enters the outer surface layer melt passageway and the inner surface layer melt passageway of the spray nozzle structure through outlets. Core layer melt enters the core layer melt runner and enters the core layer melt passageway of the spray nozzle structure through an outlet. A discharge port of the core layer melt passageway is located between a discharge port of the outer surface layer melt passageway and a discharge port of the inner surface layer melt passageway.
