Is the vulcanization process for equipment gaskets carried out at room temperature? Are there any standard requirements for this?

The rubber lining vulcanization process for equipment typically refers to the process of applying a rubber lining to the inner surface of the equipment, in order to improve its corrosion resistance, wear resistance, and sealing properties. The rubber lining vulcanization process can be divided into heat vulcanization and room-temperature vulcanization. 1. Thermosulfurization (thermo-curing): This is a process in which rubber materials are cross-linked by heating, usually at temperatures of 140–160°C. Heating can be achieved using steam, electric heating, or other methods. 2. Room-temperature vulcanization: It involves the use of rubber formulated in such a way that it can undergo spontaneous cross-linking and vulcanization at room temperature, without the need for additional heat energy. This method is very useful for equipment or large devices that cannot withstand high temperatures. Whether to use room-temperature vulcanization and the specific vulcanization conditions (temperature, time, pressure, etc.) generally depend on the type of rubber used, the design requirements of the product, and the actual application scenario. For the rubber lining vulcanization process, there are indeed standard and regulatory requirements, but these requirements may vary depending on **, region, or specific industry. For example, in China, the following standards may be referred to: - GB/T 528-2009 Rubber or plastics – Determination of tensile stress-strain properties of vulcanized rubber and thermoplastic rubber; - HG/T 21562-1995 General technical requirements for chemical anti-corrosion equipment; - HG/T 21631-1991 General technical requirements for rubber linings in chemical equipment. In the vulcanization process, it is important to follow the instructions and recommendations provided by the manufacturer, while also referring to relevant industry standards and specifications to ensure the quality and performance of the product. In certain applications, it may also be necessary to comply with relevant environmental, health, and safety regulations. Therefore, when carrying out the rubber lining vulcanization process, it is necessary to consult rubber material suppliers, professional engineers, and testing institutions to ensure that the vulcanization process and its results meet all relevant requirements. .
