Which failure cause is related to the application process of rubber lining?

Inadequate cure is a critical factor related to the application process of rubber lining. The curing process is essential for achieving the desired physical and chemical properties of the rubber material. If the rubber is not cured adequately, it can result in weaknesses in adhesion, flexibility, and overall durability of the lining. An incomplete cure can lead to issues such as blisters, peeling, or delamination, which ultimately compromise the performance of the lining. Proper curing ensures that the rubber reaches its optimal performance characteristics, making it crucial during application.

The other options, while important for different reasons in the application process or overall effectiveness of the rubber lining, do not directly pertain to the application process failures leading to immediate concerns. For example, using the correct rubber type is about selecting the right material for the environment, while proper storage ensures the material maintains its integrity before application. High temperature processing can affect the curing but in a different context from inadequate curing itself. Therefore, the focus on inadequate cure specifically addresses a direct failure cause during the application of rubber lining.
