It is one of the important varieties among the eight major synthetic glues. Polyurethane glue has excellent shear strength and impact resistance characteristics, is suitable for various structural bonding fields, and has excellent flexibility characteristics. Polyurethane glue has excellent rubber characteristics and can adapt to the bonding of substrates with different coefficients of thermal expansion. It forms a soft-hard transition layer between the substrates, not only has strong bonding force, but also has excellent buffering and shock-absorbing functions.

[0046] The implementation principle of the utility model is as follows: first, high-temperature steam is generated by the steam generator 6, and is passed through the first conduit 704 and the first through hole 707 to enter the inner sphere 703 in sequence. The second through hole 708 is blocked by the outer sphere 702, so the high-temperature steam cannot pass through, and can only enter the sealed cavity 2 through the third through hole 709 and the third conduit 706, and heat the raw materials in the device body 1; while heating, the first motor 4 drives the stirring paddle 5 to rotate, stirs the raw materials, and makes them contact the heat source as much as possible for heating, and while the stirring paddle 5 rotates, it drives The scraper scrapes the material as much as possible to reduce the possibility of its adhesion; the steam that has heated the raw material enters the steam collection tank 9 through the steam outlet pipe 8, and the low-temperature steam is initially heated by the heat pump 10, and the heated steam is then passed into the steam generator 6 for further heating. After it reaches the temperature required for heating, the above steps are repeated, and heating is continuously performed, and the utilization rate of heat is improved; finally, after heating for a period of time, when the inner wall of the device body 1 accumulates a lot of residues that cannot be scraped off by the scraper, when the device body 1 needs to be cleaned, unplug the plug 1 7, remove the handle 15 from the storage plate 16, and return the plug 17 to its original position to prevent it from being lost, then open the cover plate at the visual window 3, insert the cleaning nozzle 13 into the device body 1, and start the second motor 701 at the same time to drive the outer sphere 702 to rotate 90 degrees. At this time, the third through hole 709 is no longer connected to the third conduit 706, and the high-temperature steam no longer enters the sealed cavity 2. The second through hole 708 rotates to a position connected to the first conduit 704, and the first through hole 707 rotates to a position connected to the second conduit 705. Through the first conduit 704 and the second through hole 708 The introduced high-temperature steam enters the high-pressure cleaning machine 11 through the first through hole 707 and the second conduit 705, increases the pressure, and is sprayed toward the inside of the device body 1 through the steam hose 12 and the cleaning nozzle 13 for cleaning. The manually rotating handle 15 cooperates with the multiple groups of circularly designed cleaning nozzles 13 to adjust the cleaning angle. The electric push rod 14 is used to adjust the cleaning depth. The steam hose 12 assists all the movement processes of the cleaning nozzle 13 until the cleaning is completed. The steam used for cleaning is also recycled heating steam, which ensures that the cleaning of the device body 1 is carried out on the basis of reasonable use of heat.
