In 1930, DuPont's only 34-year-old Dr. Carothers invented neoprene and officially launched it to the market in 37 years, creating a very good neoprene industrialization industry in the world. Neoprene is an anti-aging product with superior physical and mechanical properties, high tensile strength and elongation, good adhesion, and can be directly bonded to other rubber surfaces to provide oil resistance, sunlight resistance, ozone resistance, Anti-aging effect.
Rubber joints are also called soft joints, rubber compensators, etc .; they are made of high-strength cord fabric as a stress skeleton, and are bonded and vulcanized with inner and outer rubber layers. production. The pipe can be compensated according to the material and sphere, and it has the functions of damping, muffling and solving the misalignment of the pipe. In order to protect the connection between pipelines, reduce the transmission damage of pipelines due to vibration.
According to surveys, the service life of rubber joints and flexible rubber joints produced by our company in quality inspection and engineering applications is 15-30 years. The rubber joints for some special chemical pipes have a service life of only 5 years. Oxygen and ozone in the air will cause the rubber joint material to be broken and cross-linked, which will accelerate the aging of the rubber joint , damage the sphere and change the structure of the sphere to cause the pipe to break. With the decrease of the service life every day and the aging of the rubber itself, the rubber joints will become brittle and hard, and the rubber joints will be completely invalidated by the pipeline force, heat, corrosion and other hazards.
In order to delay and maintain rubber joints , we can use neoprene modified coatings as protective coatings on the outer surface of rubber joints ; they can be used in some commercial pipes and industrial pipes, which have low price and strong adhesion ability, especially fast self-vulcanization , Good anti-aging performance, suitable for airport pipeline rubber joints , marine pipeline rubber joints , flexible rubber joints on central air-conditioning pipes.
Specific operation method: clean the pipeline equipment room hygiene, clean the surface of the rubber joint of the connecting pipe. Use a flat file or quartz gauze to sand the surface of the rubber joint . Scrub clean with gasoline and alcohol, and paint the inner layer with neoprene paint. When the inner layer does not stick to your hands, brush the outer layer on both sides; it should not be carried out on rainy days. Apply even force when brushing the surface of the rubber joint , and the phenomenon of partial brushing, sagging or dry dragging should not occur. After painting, protect the surrounding environment, avoid the surface from falling into dust, and form a protective layer, which can alleviate the persistent and severe aging of rubber joints . However, the rubber itself has an aging phenomenon. If the rubber joint exceeds the service life or has severe cracks and water leakage, it is necessary to replace the new product as soon as possible to avoid loss.
