The outer heat insulating system with sprayed water foamed polyurethane includes a moistureproof interface layer, a heat insulating polyurethane layer, an interface layer, a light protecting mortar layer and a flexible putty layer covered to the surface of outer wall successively. The light protecting mortar layer has sandwiched netted fabric, and the corner of the outer heat insulating system is provided with corner guard. The heat insulating polyurethane layer has polyurethane foamed with water, rather than Freon, as foaming agent and high heat insulating performance, and is environment friendly.

The invention discloses a dust removal device for high-temperature dust-containing waste gas and a use method thereof, relates to the technical field of waste gas treatment, and solves the technical problem that waste heat in the high-temperature dust-containing waste gas cannot be recovered. Its technical points include the main body of the dust removal device. The main body of the dust removal device includes a shell with air inlets and exhaust ports at both ends and a filter assembly arranged in the shell. The air inlet of the shell is set in a cone shape. A heat exchanger is installed, and the refrigerant inlet of the heat exchanger is connected with the external water source. A water storage tank connected with the heat medium outlet of the heat exchanger is arranged outside the shell. "-shaped tube, and the end of the "U"-shaped tube away from the shell is lower than the horizontal plane of the bottom of the shell; the invention has the advantage of being able to recover waste heat in high-temperature dusty exhaust gas.

The invention discloses a self-hardening waterproof rubber sheath for marine electric wires, belonging to the field of cable sheaths. A self-hardening waterproof rubber sheath for marine electric wires comprises a sheath body, and the outer end of the sheath body is fixedly connected with a plurality of uniform The distributed external water blocking blocks can form a multi-layer water vapor blocking barrier on the surface of the sheath body through the arrangement of the external water blocking blocks and the external water blocking laminated mesh, thereby effectively preventing the contact of water vapor with the surface of the sheath body and reducing the impact of water vapor on the surface of the sheath body. The erosion of the surface of the sheath body reduces the corrosion and aging speed of the sheath body. At the same time, the internal annular water blocking jacket can make the surface of the sheath body harden after aging and water seepage. Bending ability to detect the water seepage of the sheath body in time, and timely maintenance to reduce safety hazards. At the same time, the water absorption expansion of the annular water blocking sheath can also form a water blocking barrier again inside the sheath body, effectively preventing the water vapor from continuing to the sheath body. internal penetration.

A turbine-drill bit assembly is disclosed. The assembly comprises a box connection turbine connected to a pin connection drill bit. The turbine has a turbine body around a turbine shaft, the turbine body having a turbine stabilizer. The drill bit has a bit gauge or a bit sleeve around a bit shank, an end of the turbine stabilizer nearest the drill bit being spaced a first maximum distance from an end of the bit gauge or bit sleeve. In addition, a shouldering interface is formed at respective abutment shouldering surfaces of the turbine shaft and bit shank when the drill bit is attached to the turbine shaft, the interface being spaced a second maximum distance from an end of the bit gauge or bit sleeve.

The invention discloses an external wall thermal insulation coat, which comprises a light adherent slurry layer adhered on external wall, a thermal insulation plate and a light smear slurry layer. Wherein, said light smear slurry layer has a network cloth in the center; the adhering slit of said thermal insulation plate is covered by self-glue belt. The invention has the advantages of anti-break, better thermal insulation effect, reduced weight of thermal insulation coat caused by light adhering slurry and light smear slurry, high strength, longer service life and the application for variable constructions.

The disclosure discloses a method for preparing a glass test sample. The method comprises the following steps: a. uniformly mixing glass raw materials according to the formula to obtain a mixed material; b. placing the mixed material in step a Carry out melting treatment in the corundum tank; c, cooling and annealing after the melting treatment is completed, to obtain a glass test sample that is integrated with the corundum tank; d, cutting off the corundum tank part of the glass test sample obtained in step c . The test results of the glass test sample prepared by the method are accurate and reliable when the mechanical and optical tests are carried out.

The invention discloses a water dispenser faucet device with an indication function. The water dispenser faucet device comprises a cold water and hot water switchover piece, a water outlet pipe, a light source, a light conduction body, a control assembly and a sensing assembly, wherein a cold water and hot water switchover switch is arranged on the cold water and hot water switchover piece, the cold water and hot water switchover piece is connected with the water outlet pipe and controls the connection state thereof with a cold water source and a hot water source of a water dispenser, the control assembly is connected to the cold water and hot water switchover piece through the sensing assembly to acquire the work state of the cold water and hot water switchover piece, and is further connected to the light source to control the light source, the light conduction body is made of a light conduction material, the light receiving surface of the light conduction body is adjacent to the light-outgoing surface of the light source, the light-outgoing surface of the light conduction body is adjacent to a water outlet of the water outlet pipe, light rays emitted by the light source are transmitted by the light conduction body and then enter the water outlet flow of the water outlet, and the light rays entering the water flow are subjected to total reflection in the water flow. With the adoption of the water dispenser faucet device with the indication function, a user can conveniently observe the water containing condition inside a container in a dark place, and light rays of the light source have small possibility of diffusing outwards, so that the dim light environment in a special dim light occasion is difficult to damage.

The invention discloses a wall greening concrete structure and a construction process thereof. The invention relates to the technical field of greening concrete, and solves the problem that the greening planting wall has a low service life because it is easily eroded by the natural environment during use. It includes a fixing frame fixed on the wall, a plurality of greening concrete layers are arranged between adjacent fixing frames, a planting groove is formed between the greening concrete layer and the wall, and nutrient soil for planting green vegetation is arranged in the planting groove layer, and there are criss-cross pores on the green concrete layer. The wall greening concrete structure prepared by the invention has good resistance to natural erosion during use, has a long service life, and is widely used.
