During the long-term operation of the kneader, due to vibration, wear, pressure, temperature and repeated disassembly and assembly, the static sealing parts of each joint surface are prone to leakage, which causes a lot of waste of oil products and affects the company's site. management.

The traditional method to control the kneader leakage is to disassemble and open the kneader, then replace the sealing gasket or apply sealant, but it is more time-consuming and laborious, and it is difficult to ensure the sealing effect, and the leakage will occur again during operation. Modern new maintenance methods mostly use polymer composite materials, of which the mature Magea technology system has excellent adhesion, oil resistance and 350% elongation, which can be disassembled without affecting the production. The leakage part is treated to achieve the purpose of resealing, and the economic benefit is remarkable. Polymer materials control leakage of the sealant joint surface, and leakage of the cooler pipe side of the main motor water cooling unit of the kneader

The tube sheet of the cooler of the kneader is affected by the medium and the welding stress, which is prone to leaking liquid and corrosion. It is repaired and protected by Mega polymer materials. It has excellent adhesion properties and resistance to temperature and chemical corrosion. And the material is solid, there is no volatile substance, it can be used safely in a closed environment without shrinking. The material has good isolation bimetallic corrosion and erosion resistance, which fundamentally eliminates the corrosion and leakage of PU polyurethane equipment in the repaired parts of the kneader, provides a long-term protective coating for the components, and manages the leakage of the kneader in China. Gradually replace the traditional method in the application.
