A device for monitoring evaporation capacity of a water surface evaporator in a process includes a water surface evaporator and a rain collector, the rain collector and the water surface evaporator having a same size of orifice area, height, and contour profile of a monitoring device. One side of the water surface evaporator is connected with a first measuring well through a pipeline, and another side of the water surface evaporator is connected with a first electromagnetic flowmeter, a water supplementing electromagnetic valve and an overflow electromagnetic valve through a water pipe. The water supplementing electromagnetic valve is connected with a water supplementing barrel through a water supplementing pipe. A water collecting barrel is installed below the special rain collector. A second magnetostrictive water level meter, a starting drainage switch and a stopping drainage switch are installed in the second measuring well.

Method and device for accurately monitoring evaporation capacity of water surface evaporator in whole process

The invention relates to an anti-fatigue cold mixed epoxy resin material, preparation method and application thereof, comprising component A and component B with mass ratio of 1:1-10:1, component A comprising fluid epoxy resin, active toughener, active diluents, coupling agent and defoamer; component B is any one of or a mixture of two or more than two of alicyclic amine or amino terminated polyether, cyanoethylamine, phenolic modified amine or hydroxyalkyl modified amine. Introduced epoxy terminated organosilicon block polyurethane prepolymer breaks the limitation that elongation at fracture of epoxy resin system based on 'sea-island structure' is difficult to break through 100%. The invention is suitable for bridge deck pavement of long-span cable bearing bridge, waterproof bonding material or used for airport pavement, municipal viaduct, ramp and other occasions with high requirements for fatigue resistance of pavement material.
