Description

Technical Field

[0001] This utility model belongs to the field of heat treatment furnace technology, specifically a heat treatment furnace suitable for the production of silicone rubber. Background Technology

[0002] Heat treatment involves heating silicone rubber products at a specific temperature for an extended period to alter their physical properties, further cure them, reduce shrinkage, and improve dimensional stability. It also enhances heat resistance, aging resistance, and durability. Heat treatment makes the internal structure of silicone rubber more uniform and dense, preventing defects such as bubbles, shrinkage cavities, and foreign matter from forming during curing. This improves the density and durability of silicone rubber products, giving them better tensile strength and torsional resistance, allowing them to adapt to more complex working environments. Furthermore, it can prevent or reduce quality problems such as deformation and cracking caused by changes in temperature and humidity.

[0003] Silicone rubber heat treatment is usually carried out in a heat treatment furnace. In existing heat treatment furnaces, the silicone rubber is usually placed directly inside the furnace body, which can easily cause the silicone rubber to stack up, thereby affecting the heat treatment effect of the silicone rubber, the quality of silicone rubber production and processing, and the use effect is not good. Therefore, this application proposes a heat treatment furnace suitable for silicone rubber production. Utility Model Content
