The present application relates to a kind of emulsified asphalt-cement-based coating technology for inducing marine sessile organism attachment, especially relates to a kind of emulsified asphalt-cement-based coating and preparation method, belongs to the cross field of marine sessile organism and marine engineering coating discipline.The material components of the present application are: cementing material, emulsified asphalt, sand, water, biological calcium powder, calcium carbonate powder, trace element, acrylic emulsion and superplasticizer.The present application can be applied to newly-built marine engineering, especially a large number of engineering in service in the ocean.It not only can improve the durability of reinforced concrete structure, and simply, economically realizes the repair of marine ecological environment.This not only greatly broadens the anticorrosion application of marine sessile organism in the reinforced concrete structure in service, but also can be widely applied to marine ecological environment repair engineering.

This invention belongs to the technical field of mining methods and discloses a method and apparatus for deep-hole slotting blasting in a cut-free riser. The method includes the following steps: clearing and leveling the site; arranging drilling positions according to rock conditions and drilling; applying salt to the inner wall of the borehole after drilling; determining the borehole network parameters, including the minimum resistance line and bottom hole distance parameters based on geological conditions and blasting requirements; determining the sealing length; loading and packing explosives according to the loading coefficient and packing; determining the blasting sequence, first blasting the shallow borehole top area, then blasting the deep-hole slotting boreholes sequentially, using a trapezoidal detonation sequence; blasting operation, connecting the detonation network, and then blasting after ensuring all safety measures are in place; and clearing the slot wall. This method calculates and determines a reasonable sealing length to improve the energy utilization rate of the explosives. This invention solves the problem of low energy utilization rate in existing cut-free riser slotting blasting methods.

This invention belongs to the field of oral mouthwash technology, specifically relating to an oral mouthwash for the prevention and treatment of oral ulcers and a method for preparing it. This invention uses self-prepared garlic extract, millet extract, and lemon extract as active ingredients, which are mixed in specific amounts. The synergistic effect of these active ingredients not only benefits qi, reduces inflammation and pain, and promotes healing, but also deodorizes, sterilizes, and freshens breath. Furthermore, this invention adds carbomer, glycerin, benzyl alcohol, citric acid, sodium hydroxide, sodium saccharin, sodium pyrophosphate, chitosan, polyvinyl alcohol, and menthol, which facilitates the rapid adhesion of the active ingredients to the treatment site and ensures rapid efficacy. Therefore, the technical solution of this invention is not only simple to prepare and fast-acting, but also highly effective in preventing and treating oral ulcers and freshening breath.
