The invention discloses a precured glass fiber cloth impregnation material. The precured glass fiber cloth impregnation material is characterized by being composed of a glass fiber cloth which is coated with adhesive by adopting a gluing machine and baked by a baking tunnel of the gluing machine, wherein the adhesive is formed by mixing 1000 parts by mass of benzoxazine-maleic amide resin solution, 15-30 parts by mass of linear isophthalic type unsaturated polyester, 0.2-2 parts by mass of an accelerant and 0.1-0.3 part by mass of initiator. A preparation method of the precured glass fiber cloth impregnation material comprises the following steps: preparing a benzoxazine-maleic amide resin solution, preparing adhesive, coating the adhesive on the glass fiber cloth by adopting a gluing machine, baking the glass fiber cloth by virtue of a baking tunnel of the gluing machine, and rolling, thus the precured glass fiber cloth impregnation material is obtained. By adopting the preparation method of the precured glass fiber cloth impregnation material, the storage time of a benzoxazine resin-based precured glass fiber cloth impregnation material can be prolonged, the fragility of a post processing product is reduced, and stratification is reduced; the precured glass fiber cloth impregnation material can be applied to mould pressing, laminating and rolling of an electric insulation or structural composite material.

The invention relates to a composite light building block and a preparation method thereof. The standard is 60*15*25cm, and the weight of the building block is 18kg. The building block is prepared by the following materials by weight percent and the slurry comprises brine: 50wt% of industrial magnesium chloride hexahydrate, gas generation agent: 0.01wt% of hydrogen peroxide and calcium hypochlorite; light burnt powder: 25wt% of light burnt magnesium oxide 85 powder, foam stabilizer: 0.001wt% of sodium dodecyl benzene sulfonate, filler: 20wt% of expandable pearlite sand, an adjusting agent: the balance of sodium hydroxide or citric acid. The invention can improve the processing property, increases the slurry flowability, is easy to cast in forming, has short production period and low manufacturing cost, increases the activity, enhances the impermeability and post strength, reduces dry shrinkage, and prevents cracking. The composite light building block has the advantages of light weight, high strength, small volume density, low heat conduction coefficient, heat insulation, sound insulation, fire prevention, heat isolation, freezing and melting resistance, little dry shrinkage, and the like. By using the gas-added building block to replace the traditional bearing building block as the building wall filling material, the self weight of the building structure is decreased, the foundation burden is reduced, and the energy and material are saved.

The invention discloses a completely innovative method for replacing interface label advertisement of a network map iconic merchant. The network map merchant can submit an application for replacementwith a merchant iconic interface label advertisement needed by the merchant online; after a network service provider authorizes the application, all new icons submitted by the iconic merchant can be replaced with the new merchant iconic interface label advertisement within the range of all network maps of the APP. All current worldwide network map service providers, such as Google Maps and Baidu Maps, do not have the service, the method is original, and the concept and implementation method of the method for dynamically replacing the network map iconic merchant interface label advertisement bythe mobile terminal merchant are provided completely and systematically for the first time all around the world.

The invention discloses a production method of magnesium sulfate monohydrate. The production method of magnesium sulfate monohydrate is characterized by comprising the following steps: adding 1200-3500 parts by mass of 90-98% concentrated sulfuric acid into 1500-2500 parts by mass of magnesium sulfate heptahydrate or 1800-3000 parts by mass of a magnesium sulfate saturated aqueous solution with the temperature of 50-90 DEG C under the condition of stirring, and stirring and reacting for 1-2 hours to obtain a suspension liquid of magnesium sulfate monohydrate; filtering the suspension liquid, washing a filter cake once by using the magnesium sulfate saturated aqueous solution, and then washing once to twice by using water; and drying the washed filter cake for 0.5-1 hour at 120-150 DEG C to prepare magnesium sulfate monohydrate. The production method disclosed by the invention is short in production process, simple in equipment, low in energy consumption and low in cost, is suitable for industrial large-scale production, and is good in commercial effect and strong in practicability.
