Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane artificial leather preparation, in particular to a coagulation tank used for preparing polyurethane artificial leather. Background Art

[0002] The coagulation tank of polyurethane artificial leather usually adopts the dipping method technology. In this technology, the polyurethane raw material is immersed in a tank containing solvents and additives, and after a certain period of coagulation and curing process, the artificial leather material is formed. This technology can achieve uniform impregnation and curing of the polyurethane material, and produce artificial leather products with good performance and appearance. At present, in the preparation process of polyurethane artificial leather, when immersed in the coagulation tank, the driving roller is usually used to transport it to the coagulation tank and immersed in the tank containing solvents and additives for dipping and curing.
