What is the difference between curing time and curing time of sealing ring?

The curing time and curing time of the sealing ring are two different concepts, which play different roles in the production and use of the sealing ring.

First, curing time

Vulcanization time refers to the time required for the sealing ring to form a certain strength from the beginning of the vulcanization reaction. Vulcanization is an important step in the production process of rubber products, which causes the cross-linking reaction between rubber molecular chains to form a three-dimensional network structure, thereby improving the elasticity, strength, wear resistance and corrosion resistance of rubber. The length of curing time depends on many factors, such as curing temperature, curing pressure, rubber material type and curing agent. In the vulcanization process, the vulcanization time needs to be strictly controlled to ensure the best performance of the sealing ring.

Second, curing time

Curing time refers to the time required from the curing stage to complete curing and final performance after the sealing ring is vulcanized. Curing is the continuation of the vulcanization reaction, which makes the cross-linking reaction between the rubber molecular chains more perfect, and further improves the strength and stability of the sealing ring. The length of curing time is also affected by many factors, such as the cooling time after vulcanization, the temperature, humidity and light conditions of the storage environment. The curing time is usually longer than the curing time because the curing process requires more time to optimise the cross-linking reaction between the rubber molecular chains.

Three, the difference summary

The vulcanization time is the time required for the sealing ring to begin the vulcanization reaction to form a certain strength, while the curing time is the time required after the completion of vulcanization to fully cure and achieve the end use performance.

The process is different: the vulcanization process mainly occurs the cross-linking reaction between the rubber molecular chains, so that the sealing ring has a certain strength and elasticity; The curing process is the continuation of the vulcanization reaction, which makes the cross-linking reaction between the rubber molecular chains more perfect.

The influence factors are different: curing time is mainly affected by curing temperature, curing pressure, rubber material type and curing agent. The curing time is more affected by the cooling time after vulcanization, the temperature, humidity and light conditions of the storage environment.

The curing time and curing time of the sealing ring play different roles in the production and use of the sealing ring, and need to be controlled and adjusted separately to ensure the best performance of the sealing ring.
