are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve. Not only can it reduce vibration and noise, but it can also compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipe systems. The main material of single ball rubber joints is rubber. In rubber joint products, there will be internal or external foaming. Some are problems with raw materials, and some are not handled properly by workers when making balls. It is cooked. Some are not enough time to make mistakes. This is a raw bag. And what exactly caused them to do this? Is such a rubber joint defective? Can the rubber joint with air bubbles still be used? Let me explain the answer to this series of questions for everyone.
1. The quality of foaming agent, check whether the foaming agent is qualified within a limited period;
2. The plasticity of the rubber material is too low. Check whether the plasticity of the rubber material meets the standard. The plasticity is good for the low-level supplementary mixing and increase the plasticity pores.
3. The mixing temperature is too high, the foaming agent decomposes early, check whether the mixer discharge temperature is too high, the stick temperature is too high, and the rubber compound is scorched. Some rubber compounds can be mixed with a small amount due to the high mixing temperature. Addition of foaming agent to the processing industry;
4.If the rubber is parked for a long time or the temperature is too high, some foaming agents will be pyrolyzed and decomposed. The rubber should be back-chained for additional processing if it is parked for a long time;
5. The rubber vulcanization speed is too fast, the formula is adjusted, check whether the critical temperature of the vulcanizing agent and the decomposition temperature of the foaming agent are close, and coordinate with each other to make the vulcanization speed match the foaming speed.
The above 5 items are the main reasons for the surface packing of the single ball rubber joint, so we must take strict precautions during normal use, so that the single ball rubber joint can serve us for a longer time.
