Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vulcanization equipment, specifically relates to a rubber product secondary vulcanization equipment. BACKGROUND

[0002] Vulcanization equipment is a key device for converting raw rubber into vulcanized rubber by adding materials such as sulfur and carbon black under high-pressure heating conditions. In addition to the commonly used vulcanization tank and vulcanization machine, which are used for primary vulcanization of rubber products, secondary vulcanization equipment is also included.

[0003] Secondary vulcanization equipment is a key device for further improving the physical and chemical properties of rubber products by continuing to heat and vulcanize after reaching a certain degree of vulcanization. The core function of secondary vulcanization equipment is to re-vulcanize rubber products that have undergone primary vulcanization by precisely controlling parameters such as vulcanization temperature, time, and pressure. This step is crucial for improving key performance indicators such as tensile strength, resilience, hardness, swelling degree, density, and thermal stability of rubber products. At the same time, secondary vulcanization also helps to eliminate incomplete vulcanization or products that affect rubber crosslinking density during primary vulcanization, thereby further improving the quality and performance of rubber products.
