The invention relates to the technical field of pharmaceutical preparations, in particular to a folic acid tablet with low oxidation impurities and a preparation method thereof, and discloses the folic acid tablet with low oxidation impurities, which comprises the following components: a mixture of folic acid and an antioxidant, a porous starch; wherein the mass ratio of the mixture of the folic acid and the antioxidant to the porous starch is (1-2): (3-4); the mass ratio of the folic acid to the antioxidant is 1: (1-3); the invention discloses a folic acid tablet with low oxidation impurities and a preparation method thereof, folic acid and an antioxidant tert-butylhydroquinone are mixed and crushed together, the folic acid can be fully wrapped by the antioxidant, oxidation of the folic acid is prevented or delayed, the particle size D90 of the mixture is controlled to be less than 5 [mu] m, then the mixture is fully mixed with porous starch, and the folic acid tablet with low oxidation impurities is prepared. By utilizing the porosity of the porous starch, the folic acid and the antioxidant can be adsorbed in concave holes of the porous starch, and meanwhile, the contact of the folic acid with oxygen and light is reduced, so that the generation of oxidized impurities in the long-term placement process is reduced.

The shoe comprises a shoe outsole, a shoe seed sole and a vamp, a cavity is formed in the shoe outsole, penetrating through holes are formed in the front end face and the rear end face of the cavity and communicated with the outside, welt protrusions are arranged on the left side edge and the right side edge of the cavity, and protective parts are arranged at the positions, not provided with the welt protrusions, of the shoe outsole. The bottom of the vamp is connected with the bottom of the shoe insole through the connecting part to form a shoe cavity for a foot to penetrate through, and the shoe insole and the shoe outsole are pressed into a whole after the adhesive in the cavity is heated. According to the shoe, the waterproofness of the connection of the vamp and the sole is improved, the protection of the toe cap and the heel is enhanced, the attractiveness of the shoe is further improved, the invention further provides a shoemaking process of the shoe, and the shoe is convenient to manufacture.

The packaging mechanism for waterproof membrane material processing comprises a top plate, vertical rods connected with the left side end and the right side end of the top of a winding rack are arranged at the corners of the bottom of the top plate correspondingly, and a linear sliding table, a transverse plate, a plurality of first telescopic push rods, a fixing plate, a vertical plate, an inserting cylinder and a mounting cylinder are arranged at the corners of the bottom of the top plate correspondingly. The fixing plate is provided with a pressing and fixing module used for pressing and fixing the protective film, the fixing plate is further provided with a shearing module used for shearing the protective film, and the vertical plate is further provided with a locking module used for locking the inserting cylinder. According to the packaging mechanism for waterproof membrane material processing, the basic requirement for winding and wrapping a protective film on the surface of the axial side end of the rolled waterproof membrane material can be met, and the protective film can be automatically and rapidly moved, so that the treatment efficiency for winding and wrapping the protective film on the surface of the rolled waterproof membrane material is improved, and the packaging efficiency is improved. And therefore, the overall efficiency of packaging and processing the waterproof membrane material is prevented from being influenced.

This invention relates to the field of composite material preparation technology, specifically to a method for preparing continuous glass fiber reinforced polyurethane core profiles, comprising the following steps: preparing continuous glass fiber, isocyanate component, polyol component, chain extender, coupling agent, catalyst, antioxidant, and ethanol, wherein the isocyanate index of the isocyanate component and the polyol component is 0.8-1.1. This invention effectively solves many defects of existing technologies by constructing a multi-dimensional synergistic optimization system, possessing significant technical advantages and practical value. Regarding interfacial bonding, a composite modification method is adopted, which significantly improves the interfacial bonding strength between the fiber and the polyurethane matrix, fundamentally improving the conduction efficiency of the material's mechanical properties, resulting in a significant improvement in the material's core mechanical properties such as tensile, bending, and impact resistance.

This utility model relates to the field of gear processing technology, specifically to a tooling for loading gear parts for carburizing and quenching. Through the setting of a height adjustment component, the spacing between the support rods can be adjusted according to the size of the gear. The two ends of the gear hanger are inserted into the hanger limiting grooves of the front and rear support rods. The hanger limiting grooves are evenly distributed to ensure the gear hanger is horizontally stable. Limiting blocks are installed at both ends of the gear hanger via threads. The diameter of the limiting blocks is larger than the hanger limiting groove to prevent the gear hanger from falling out of the groove. Gear parts are sequentially fitted onto the gear hanger, with the gear inner hole and gear hanger having a clearance fit. The teeth of each gear are inserted into the corresponding gear limiting groove. The gear limiting grooves are evenly spaced to avoid contact between gears, ensuring the tooth surface is fully exposed. The carburizing medium can fully coat the tooth surface. Furthermore, the gear hanger is used for batch loading and unloading. After quenching, the gear hanger can be tilted to quickly remove the gear.
