The present invention provides a concrete protective agent and a preparation method thereof, and a concrete protective film and a preparation method thereof. The concrete protective agent provided in the present invention includes the following components: water, oxalic acid, a defoaming agent, and a film-forming agent. When the concrete protective agent provided in the present invention is used for concrete protection, oxalic acid in the protective agent can react with calcium ions in concrete for in situ generation of calcium oxalate monohydrate inside and on a surface of concrete to obtain a protective film with strong adhesion to concrete. The film-forming agent in the protective agent is used as a template to adjust and control growth of calcium oxalate crystals, so as to improve waterproof performance and corrosion resistance to sulfate and chloride ions of the protective film. Preparation methods provided in the present invention are simple and practical and are suitable for mass production.

Brake disks with integrated heat sink are provided. Brake disk includes a fiber-reinforced composite material and an encapsulated heat sink material impregnated into the fiber-reinforced composite material. The encapsulated heat sink material comprises a heat sink material encapsulated within a silicon-containing encapsulation layer. Methods for manufacturing the brake disk with integrated heat sink and methods for producing the encapsulated heat sink material are also provided.

A water-soluble texture enhancing composition, including a base powdered composition including powdered calcium carbonate, and a soluble packaged bleach, provided in sufficient quantity so that upon mixing with the base composition and water to form an aqueous slurry, and being agitated, the bleach provides an anti-microbial function for an extended period, preferably up to 80 hours. Also, a process for preparing a textured composition is provided, including providing a base powdered texture composition, providing soluble packaged bleach and mixing same with the base composition, and adding water to create an aqueous slurry, the soluble packaged bleach being provided in sufficient amount for inhibiting microbial growth in the solution for an extended period, preferably up to 80 hours.

The present invention relates to a method for impregnating concrete with a non-aqueous electrolyte characterized in that an electric field is applied between electrodes mounted on the concrete surface and/or embedded in the concrete such that the non-aqueous electrolyte migrates into the concrete. Preferably, lithium ions are dissolved in the non-aqueous electrolyte.

A glaze resistant to wax block bonding, a ceramic resistant to wax block bonding and a preparation process thereof are disclosed. The components of the disclosed glaze are made up of potassium feldspar, lithium feldspar, calcium carbonate, talc, kaolin, wollastonite, quartz, alumina and nanopowder, the components being in the following parts by weight: potassium feldspar 30, lithium feldspar 8, calcium carbonate 10, talc 6, kaolin 10, wollastonite 10, quartz 26, alumina 1 and nanopowder 20. Sources of the starting materials required are abundant, the price is low, the production cost is low, and a glaze surface layer resistant to wax block bonding is formed on the surface of the ceramic resistant to wax block bonding produced, thereby effectively solving the problem of the difficulty of removal of molten wax from the burning of candles which has dripped down and hardened on the surface of ceramic.
