The invention relates to a non-curing polyurethane waterproof coating and a preparation method thereof, belonging to the technical field of polyurethane waterproof coating. It consists of the following raw materials in percentage by weight: prepolymer 13-20%, asphalt 30-65%, latent curing agent 1.0-1.5%, compatibilizer 3-15%, thermoplastic elastomer 2-9%, powder Sexual filler 0-30%, the prepolymer is a reaction composition of polyether and isocyanate. The core of the invention improves the material ratio and polymerization process of polyurethane, which overcomes the problems that hot-melt asphalt materials need to be heated by machines, etc. It is convenient for construction and has good fluidity. The waterproof layer without internal stress can also have good adhesion with the coiled material. It can be composited waterproof to form a waterproof layer that overcomes the cracking of the base layer and prevents puncture. The process is simple and can be quickly constructed. It needs maintenance and has fast work efficiency, which can become the development direction of building waterproofing in the future.

The invention discloses a radiator using a double-sided high-efficient water-cooled spiral structure to improve efficiency. The radiator comprises a base plate, a first cover plate and a second coverplate; a circular groove is formed in the surface of the base plate, a water-cooled channel is formed in the bottom of the circular groove, the water-cooled channel is a worm groove, a first flow guiding hole is formed in one end of the water-cooled channel, and a second flow guiding hole is formed in the other end of the water-cooled channel; a first water inlet and a second water inlet are formed in one side surface of the base plate, a channel is formed in the other side surface, wherein the second water inlet is communicated with the second flow guiding hole, and the channel is communicated with the first water inlet and the first flow guiding hole. The invention aims at providing the radiator using the double-sided high-efficient water-cooled spiral structure to improve the efficiency, and heat generated by electronic components can be dissipated efficiently and reliably to ensure the normal operation of the electronic components.

The invention discloses a method and device for controlling washing of a station of a bottle washing machine. According to the method for controlling washing of the station of the bottle washing machine, when a central control unit confirms that a bottle or a bucket is placed on the station according to information fed back by a detecting device, a station valve, corresponding to the station, on a washing pipeline is controlled to be opened, a corresponding water pump on the washing pipeline is controlled to operate at a high speed, and a spraying head on the station is made to wash the bottle or the bucket in a spraying mode; when the central control unit confirms that no bottle or bucket is placed on the station, the station valve is controlled to be closed, the water pump is controlled to operate at a low speed, and the spraying head is made to stop washing. The device for controlling washing of the station of the bottle washing machine comprises the central control unit, the detecting device, the station valve, the water pump, the spraying head and the washing pipeline, wherein the detecting device, the station valve and the water pump are connected with the central control unit electrically, and the water pump, the station valve and the spraying head are installed on the washing pipeline in sequence in the flowing direction of water in the washing pipeline. The method and device for controlling washing of the station of the bottle washing machine has the advantages that energy consumption, water consumption and acid and alkali water consumption can be reduced and the phenomenon of leakage of the station is avoided.

The invention discloses a production technology of a waterproof and heat-insulated integrated board. The production technology comprises the following steps of: firstly, compositing an enhanced isolating material at one side of a waterproof roll; pre-heating the waterproof roll composited with the enhanced isolating material by a pre-heating device; compositing an heat-insulated material at one side of the waterproof roll composited with the enhanced isolating material after pre-heating; and finally, covering another pre-heated waterproof roll on the surface of the heat-insulated material. By providing the enhanced isolating material at one side of the waterproof roll, not only can the bonding strength between the enhanced isolating material and the waterproof roll be enhanced, but also the waterproof roll and the heat-insulated material can be effectively isolated; the condition that the waterproof roll is contacted with the heat-insulated material for a long time to cause chemical reaction can be avoided; a plasticizer inside the roll is prevented from migrating; the quality of the product is ensured; a procedure of pre-heating the waterproof roll is added before the waterproof roll and the heat-insulated material are composited; and the phenomenon that a waterproof layer and an insulating layer are stripped after the board is molded can be avoided, and the performance and quality of the board are further improved.
