are the main components of long-distance pipelines. When they are affected by the environment during use, they will cause aging and corrosion, which will affect the service life of the rubber joints. Therefore, special attention should be paid to maintenance during the installation and use of rubber joints. Rubber joints are mainly produced from natural and synthetic rubber. The rubber joints have a certain service life, and they will age over time. In terms of preservation, in addition to being placed in a cool and dry place out of direct sunlight, it should also be kept away from things containing strong acids and alkalis. In addition, there is a way to extend the service life: when the rubber joint is not in use, you can apply some talc powder on its appearance. Didn't you see that there was a layer of white powder on the balloons and the rubber bands that had just been bought? The white powder is talcum powder, which is easy to buy, economical and convenient, and the effect is very good.
Basic characteristics of rubber joints: 1. During the molding of rubber joints, the cohesive force due to the elastomer can not be eliminated due to the large pressure. When the mold is released from the mold, it often produces extremely unstable shrinkage (the shrinkage rate of rubber due to rubber Different kinds of differences), it must take some time to be gentle and stable. Therefore, at the beginning of the design of a rubber product, it is necessary to calculate the fit carefully regardless of the formula or the mold. If not, the size of the product is likely to be unstable and the quality of the product will be lowered. 2. Rubber is a hot-melt and thermosetting elastomer, and plastic is a hot-melt and cold-set. Due to the different types of sulfide rubber, the temperature range of molding and curing of rubber is also quite different. It can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber joints need to be appropriately adjusted at any time. If there is no, there may be differences in product quality. When using rubber joints, avoid light as much as possible. Long-term stretching or shrinkage will cause plastic deformation, which will cause internal chain breaks in the rubber joints, affect the mechanical and physical properties of the rubber joints, cause sudden tearing when stress is concentrated, and resist acid. When using alkali and corrosion-resistant rubber joints, try to make the medium as simple as possible, especially for rubber products used in chemical companies. Our rubber joints have a certain corrosion resistance, but the strong corrosive pipes need to be lined with PTFE, so that the rubber can be increased. Joint life, the temperature resistance of any kind of rubber joints is about -20 ℃ -150 ℃, can not be used in extreme environments. When the rubber joints are buried, install an underground protection device to prevent crushing. Avoid sharp edges during installation. The object is in contact with the welding slag.
