Description

Technical Field

[0001] The utility model relates to the technical field of fluorosilicone rubber production, in particular to a dust removal device for fluorosilicone rubber production. Background Art

[0002] Fluorosilicone rubber maintains the excellent properties of organic silicone materials, such as heat resistance, cold resistance, high voltage resistance, and weathering resistance. Due to the introduction of fluorine-containing groups, it also possesses the excellent resistance to hydrogen solvents, oils, acids and alkalis, and lower surface energy of organic fluorine materials. Fluorosilicone rubber production involves melting plastic pellets and then using a rubber mixer to refine the plasticized raw rubber with compounding ingredients to form a rubber compound. Dust and impurities often cling to the surface of the plastic pellets, requiring prior dust removal.

[0003] The existing dust removal method is usually screening dust removal. However, the dust and impurities released during screening dust removal are easily reattached to the surface of plastic particles, resulting in poor dust removal effect. In this regard, we propose a dust removal device for fluorosilicone rubber production to solve the above-mentioned problems. Utility Model Content
