Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane foaming, in particular to polyurethane foaming equipment. Background Art

[0002] Polyurethane is a polymer compound that is widely used in many fields today, such as construction, automobiles, aviation industry, and structural materials for thermal insulation. In the polyurethane foaming production process, the corresponding raw materials are often placed in a foaming tank in a precise proportion, and then stirred at high speed for mixing and foaming. During the foaming process, the foaming agent and carbon dioxide gas will be volatilized and discharged. At the same time, the foamed material can be discharged through the discharge pipe at the bottom of the foaming tank. However, the existing polyurethane foaming equipment cannot be stirred in multiple directions during use, which will still make the mixing effect of some raw materials poor, making it inconvenient to quickly foam and mix them, and causing some raw materials to adhere to the inner wall of the equipment. The temperature of the polyurethane inside the equipment changes greatly during foaming, and the quality of the insulation layer is unstable. For this reason, we have proposed a polyurethane foaming equipment. Utility Model Content
