Technical Field

[0002] Polyurethanes are polymers composed of organic units linked by urethanes. Although most polyurethanes are thermosetting polymers that do not melt when heated, polyurethanes are also thermoplastic. Polyurethane polymers are traditionally and most commonly polymerized by reacting dimer or trimer isocyanates with polyols. Because polyurethanes contain two monomers that polymerize alternately, one after the other, they are classified as alternating copolymers. The isocyanates and polyols used to prepare polyurethanes contain, on average, two or more functional groups per molecule. Polyurethanes are also used to make scrapers.

The polyurethane scraper processing device with waste collection function provided by the utility model has the advantages of being relatively simple to operate, being able to more effectively collect the debris generated during cutting, and squeezing the debris together, making it convenient to perform other operations on the debris. However, when the device needs to cut a wider plate into strips, the worker needs to manually push the plate, which is easy to cause injury to the worker during cutting. Utility Model Content
