What are the causes of cracking of rubber joints and how to prevent them
The subject of rubber joint products is that they are made of rubber. There are many kinds of rubber. Among them, aging-resistant and crack-resistant rubber is also common in the market. Even if the protection measures are not in place, the best rubber is inevitably aged and cracked. Once the product is cracked, it cannot be repaired and can only be considered a scrap product, so the necessary protective measures are essential, so today we will talk about what are the reasons for the cracking of the rubber body and what are the best protective measures:
Many cracking phenomena of rubber joints are caused by the installation environment. For example, long-term exposure to UV light in the open air during installation. In this case, aging is inevitably accelerated, regardless of the type of glue. The main cause of rubber joint cracking is aging cracking. Therefore, it is very important to take anti-aging measures for the product. Outdoor installation needs to avoid sunlight as much as possible. In addition to these, let's take a look at what we need to pay attention to when installing and using: when we use mechanical rubber joints to connect, the strength of the joint can only reach 40% to 50% of the strength of the band body. When the quality is better, the strength of the joint can reach 60% to 70%, while the strength of the hot rubber joint can reach 80% to 90%. It is necessary to ensure that the joint method is accurate and free from quality defects.
1 . The strength of the joint part is relatively low, and if the bonding method is not accurate, the strength of the joint will be even lower, or even cracking will occur.
2 . The link is not long enough in the process of use, forcibly exceed the link length, and arbitrarily expand the shrinkage range may also appear cracks.
3 . After installation, cracks may also appear if the belt is pulled elsewhere in the pipe at will beyond the expansion range.
4 . Under the influence of outdoor bad weather, exposure to the sun, etc., it may crack below the use temperature.
5 . In the vulcanization process, the rubber used is not good or has been since the vulcanization, excessive grinding, rust on the wire rope, etc., the strength of the joint will be greatly reduced, and the joint is easy to pull off in the process of use damage. The phenomenon of open mouth.
