This invention discloses a composite coating for concrete structures, comprising a sealing primer, an intermediate coat, and a topcoat. The sealing primer is a polyurea coating with modified concrete added, the amount of modified concrete being 3%–6% of the coating weight, and the thickness of the sealing primer being 20–100 μm. The intermediate coat is a polyurethane coating with steel powder added, the amount of steel powder being 3%–6% of the coating weight, and the thickness of the intermediate coat being 80–200 μm. The topcoat is an epoxy resin coating with molybdenum disulfide powder added, the amount of molybdenum disulfide powder being 1%–4% of the coating weight, and the thickness of the topcoat being 50–100 μm. The sealing primer of this composite coating fills concrete pores and cracks, improving structural density and providing a good foundation for subsequent coatings. The intermediate coat enhances overall strength and impact resistance, while the topcoat provides excellent anti-friction properties and chemical stability, blocking external erosion. The synergistic effect of these three components significantly extends the service life of concrete structures in harsh environments.

The invention provides a liquid crystal panel etching solution and application thereof. The liquid crystal panel etching solution comprises a main agent and an auxiliary agent, the main agent comprises an oxidizing agent, organic acid, organic alkali, a cone angle maintaining agent, a metal interface improving agent, an etching speed regulating agent, a stabilizing agent and water; the auxiliary agent comprises organic acid, a metal chelating agent, organic alkali, an etching speed regulator, a stabilizer, an alloy residue remover and water. The etching liquid provided by the invention does not contain F, is environment-friendly, is small in IGZO corrosion, does not affect the characteristics of a panel, can maintain the morphology of a large-angle metal angle, solves the problem of interface opening caused by small CD Loss, guarantees the size of a metal taper angle, can guarantee the service life of high copper concentration and the safety of the liquid medicine, and is free of etching residues.
