This invention discloses a pretreatment method for ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. It utilizes mature trees planted vertically at the slope toe, intersecting with horizontally planted mature trees on the slope surface to form a framework of living trees. Simultaneously, waterproof soil bags filled with rock and soil fragments are used to construct soil pillars or walls, providing support for the horizontally planted mature trees. The framework of living trees and the soil pillars or walls together form a retaining structure to prevent potential landslide impacts. The spaces between the soil pillars or walls create a drainage channel for the landslide dam, collectively providing ecological prevention and coordinated emergency response to colluvial deposits and landslide dams on riverbanks. This invention can replace the post-treatment technology of emergency excavation of spillways after landslide dam formation. By pre-constructing the drainage channel before the dam forms, it achieves ecological protection of riverbanks, reduces the risk of landslide damming, and is easy to construct.

This invention relates to the field of biomass functional materials technology, specifically disclosing a superhydrophobic radiation-cooled wood and its preparation method. The preparation method is as follows: 1) Immersing wood in a sodium chlorite / acetic acid system to remove lignin and constructing a porous wood framework; 2) Using silicon, calcium, and aluminum sources, cement-based nanoparticles are generated in situ on the wood cell walls to obtain a highly efficient scattering micro-nano photonic structure; 3) Using fluorosilanes for low surface energy modification, the superhydrophobic radiation-cooled wood is obtained. The superhydrophobic radiation-cooled wood prepared by this invention has a solar reflectivity ≥90%, an atmospheric window emissivity ≥99%, a surface water contact angle >150°, and an environmental cooling range >10℃. Furthermore, the preparation process is simple, environmentally friendly, and suitable for large-scale production, showing broad application prospects in building energy conservation, outdoor applications, and other fields.

This invention discloses a preservation film, preservation device, and preservation method for edible fungi. The film includes a preservation film substrate in which phosphorescent materials are dispersed. The phosphorescent materials emit light with wavelengths of 470-580 nm under ultraviolet light excitation. The ultraviolet-phosphorescent dual-effect preservation film constructed by this invention can continuously release room-temperature phosphorescence after short-term ultraviolet excitation, achieving a low-energy, intermittent, and long-lasting dual-preservation light response, avoiding tissue damage and accelerated water loss caused by prolonged direct UV irradiation. Furthermore, the composite material used is biodegradable, low-cost, and environmentally friendly.

The invention discloses bio-based epoxy resin modified asphalt. The bio-based epoxy resin modified asphalt is prepared from a first component and a second component, the first component comprises epoxy resin, matrix asphalt, a diluent, a plasticizer, a flexibilizer and a defoaming agent; the second component comprises a modified amine curing agent and a polyether amine curing agent. Wherein the modified amine curing agent comprises bis (cyanoethyl) pentamethylene diamine, bisphenol A diglycidyl ether, a solvent B and a catalyst B in a mass ratio of 80: (5-15): (3-6): (3-6). Bio-based 1, 5-pentamethylene diamine is subjected to cyanoethylation to prepare bis (cyanoethyl) pentamethylene diamine, and then primary amino of the bis (cyanoethyl) pentamethylene diamine and phenolic hydroxyl of bisphenol A are subjected to dehydration condensation or nucleophilic substitution reaction under catalysis to form an amine-phenol grafted structure, so that the cured epoxy asphalt has high toughness, and the toughness of the epoxy asphalt is improved. The compatibility and reaction activity of the curing agent and an asphalt-epoxy system can be improved.
