Steam is typically used to create the heat and pressure required for curing.
However, using steam brings a number of disadvantages such as:
-
Lack of flexibility in setting individual parameters
-
High cost of steam
-
High maintenance effort
-
Need for additional protective antioxidants in some cases
-
Risk of quality impairment as a result of of local overheating following condensation.
Nitrogen-based Solution
In order to overcome these disadvantages, BOC has developed a gas-based tyre curing concept that replaces steam with nitrogen as the pressure agent.
Operators of nitrogen-operated tyre presses can select the system pressure independently of the curing temperature. The elimination of steam means that the rubber no longer overheats as a result of excessive steam, and less steam condenses in subsequent stages of the curing process.
