The invention relates to the technical field of environment protection, in particular to a multifunctional copper wire separator. The multifunctional copper wire separator comprises a machine frame. The machine frame is sequentially provided with a crushing machine and a separating machine from top to bottom, a feed port is formed in the upper end of the crushing machine, and a discharge port communicated with a feed port of the separating machine is formed in the lower end of the crushing machine. The multifunctional copper wire separator is characterized in that a spraying mechanism is arranged in the crushing machine, a plastic discharge port and a metal discharge port are formed in the left end and the right end of the separating machine respectively, a plastic screening mechanism is arranged below the plastic discharge port, and a metal screening mechanism is arranged below the plastic discharge port; the plastic screening mechanism comprises a water storage tank and a sieve, one end of the water storage tank is communicated with the metal screening mechanism through a water guide pipe, the other end of the water storage tank is connected with the spraying mechanism through a water inlet pipe, and the water inlet pipe is provided with a water pump. The multifunctional copper wire separator has the advantages that the crushing rate and the separating rate are high, secondary pollution is avoided, the cost is low and the size is small.

The invention discloses a foam concrete roof insulation board capable of detecting internal humidity and a manufacturing method thereof and belongs to the technical field of construction. A humidity sensing framework can be introduced into a foam concrete insulation board body. Once water enters the foam concrete insulation board body, the humidity sensing framework can sense humidity quickly andconduct water to a humidity display and damp removal ball. After a water accumulating sponge ball in the humidity display and damp removal ball is diffused autonomously, a display propelling expansionball absorbs moisture to expand, so that a humidity display petal blooms by imitating a flower petal, so that on the one hand, a user can be prompted that the foam concrete insulation board body is affected with damp internally and on the other hand, water diffusion and release of water in the water accumulating sponge ball can be accelerated and an evaporation-assisting water absorbing fluff canbe driven to transfer water outward for efficient evaporation to improve the damp affecting condition in the foam concrete insulation board body based on high frequency jittering by means of a disintegration automatic ball specially arranged in the water accumulating sponge ball as the disintegration automatic ball is disintegrated quickly after encountering with water.

The invention discloses a preparation method of a water-borne PU adhesive for zero DMF immersion gloves. The water-borne PU adhesive is prepared from the following components in percentage by weight:70-80% of water-borne polyurethane dispersion bodies, 2-5% of a wear-resistant agent, 1-5% of a wax emulsion, 0.5-3% of a pore opener, 0.1-1% of a wetting agent, 2-3% of an adhesive, 1-4% of a foamingagent, 1-4% of a foam stabilizer, 0.4-0.8% of a synthesis thickener, and 10-20% of deionized water. The preparation method includes the following steps that S1, a certain amount of the aqueous polyurethane dispersion bodies is taken and placed in a mixing tank; and S2, a mixer is arranged outside a stainless steel mixing cylinder, a drive end of the mixer extends into the stainless steel mixing cylinder, and mixes at a rotating speed of 500-1100 r / min. According to the preparation method, a PU adhesive does not use DFM, and is safe and environmental-friendly; by adding the wear-resistant agent, the pore opener, the wax emulsion, and the like, the softness and hand feeling of the gloves made by the PU adhesive are improved; and meanwhile, the hardness and wear resistance of the gloves areimproved, and the gloves are soft and wearable.
