The present application relates to the technical field of artificial board, and discloses a kind of mould-proof composite board for wardrobe and a preparation method thereof.The composite board for wardrobe prepared by the present application is prepared by using rubberwood sheet as main raw material, impregnating treatment with mould-proof and antibacterial agent, and then adhesive treatment with adhesive containing mould-proof and antibacterial agent.The composite board realizes long-term inhibition of mould through multi-mechanism sterilization of components, synergistic effect and material level protection, and is suitable for wardrobe application in high-humidity environment.In addition, the use of mould-proof and antibacterial adhesive also endows the composite board with excellent bonding strength.

The present invention discloses a controlled-release type polymeric ferric sulfate water treatment agent and its preparation method, belonging to the technical field of water treatment functional materials. The water treatment agent consists of polymeric ferric sulfate, an iron ion color indicator, a gel matrix, a cross-linking calcium agent, amino diatomaceous earth, a pore-forming agent and an inert filler. The preparation method includes: first preparing a network gel, then preparing soft materials, and finally obtaining the product through pill-making and drying. The present invention realizes the slow release and controllability of polymeric ferric sulfate, and the color indicator can directly reflect the consumption state of polymeric ferric sulfate, facilitating storage, transportation, dosing and recovery.

This invention belongs to the field of agricultural microbiology technology, and discloses a strain of Sphingomonas, a microbial agent, its preparation method and application, specifically disclosing a strain of Sphingomonas (… Sphingomonas Microbial agent (sp.) R7 was deposited on March 31, 2025, at the China Center for Type Culture Collection (CCTCC), Wuhan University, Wuhan, China, with accession number CCTCC NO: M 2025634. The invention discloses a microbial agent containing this bacterium, its preparation method, and its application in improving soil and / or promoting rice growth, as well as in reducing cadmium content in the aboveground parts of rice. This microbial agent not only increases the content of nutrients such as nitrogen and phosphorus in the soil, thus improving soil quality, but also significantly increases the dry matter weight of rice roots, stems, leaves, and brown rice, promoting rice plant growth; it also concentrates cadmium in the rice roots, reducing the cadmium content in the aboveground parts of rice.

The invention relates to the technical field of vaccine adjuvants and drug delivery, and discloses a 3D-MLA and QS-21 composite adjuvant as well as a preparation method and application of the 3D-MLA and QS-21 composite adjuvant. A saponin QS-21; polyethylene glycol sodium alginate; embedding particles with pH-sensitive calcium chloride; the preparation method of the vaccine antigen comprises the following steps: performing pegylation modification on sodium alginate; embedding calcium chloride with a pH sensitive polymer, and carrying out spray drying to prepare cross-linking agent particles; dissolving the synthetic monophosphoryl lipid A and saponin QS-21 to prepare a composite adjuvant solution; mixing the adjuvant solution with the pegylated sodium alginate solution to prepare a precursor preparation; and adding antigen and cross-linking agent particles into the precursor preparation, and uniformly mixing to obtain a final product. According to the invention, the composite adjuvant is delivered through the pH responsive in-situ gel, an immune reservoir is formed, and a powerful and lasting comprehensive immune response biased to the Th1 type is safely induced.

The utility model discloses a rewinding follow-up roller long-acting lubricating mechanism which comprises a follow-up roller, end shafts at the two ends of the follow-up roller are arranged on a lubricating assembly, the lubricating assembly comprises a lubricating body, an oil cavity is formed in one end of the lubricating body, an oil injection hole communicated with the oil cavity is formed in the side wall of the upper portion of the lubricating body, and a bearing is arranged in a cavity body of the oil cavity in a sleeved mode. An end shaft of the follow-up roller is fixed to a bearing inner ring, a sealing cover is arranged on the portion, located on one side of the oil cavity, of the lubricating body through bolt connection, and a sealing ring is arranged between the sealing cover and the lubricating body. The long-acting lubricating mechanism for the rewinding follow-up roller stores lubricating oil through the oil cavity, is matched with the oil injection hole to conveniently supplement oil, and is combined with the sealing cover and the sealing ring to form a reliable sealing structure, so that the leakage of the lubricating oil can be effectively reduced, the lubricating period is prolonged, and the maintenance frequency is reduced; meanwhile, the stable assembly structure of the bearing and the end shaft can improve the running stability and prolong the service life of the follow-up roller.

The invention relates to the technical field of ferro-titanium alloy smelting, in particular to a ferro-titanium alloy smelting process based on a composite aluminum material aluminothermy method, which specifically comprises the following steps: modifying aluminum skimmings by using an auxiliary agent for pretreatment, and preparing the ferro-titanium alloy through gradient mixing and layered distribution, aluminothermy reaction initiation and smelting. The composite fluoride-MgO compound is melted at the initial stage of the reaction, and the composite fluoride and the nano MgO form a physical-chemical dual membrane rupture effect. CaO and BaB6 micro powder are wrapped by Li2B4O7, so that the effects of protecting and avoiding layering are achieved. Internal active components are gradually released, so that the effective action time of the additive is prolonged. Li < + > and BaB6 which are released by melting Li2B4O7 react with each other to gradually generate BF3, and F <-> is chemically corroded to form synergistic membrane rupture of internal and external clamping, so that the membrane rupture efficiency is improved. CaO reacts with Li2B4O7 to generate Ca3B2O6, so that the slag phase viscosity is reduced, and the slag-metal separation is improved. And meanwhile, CaO has the desulfurization capacity, melt purification can be achieved, and the recovery rate of titanium and the alloy purity are improved.
