Silicone Rubber Drying Tunnel Oven

The Silicone Rubber Drying Tunnel Oven is a highly efficient continuous industrial drying system specially designed for secondary vulcanization, drying, preheating, and aging testing of silicone rubber products. The equipment adopts a horizontal or vertical hot air circulation system combined with high-precision temperature control technology, ensuring uniform heating of silicone rubber products during continuous conveying.The internal chamber is commonly constructed with stainless steel materials to prevent product contamination and effectively remove volatile substances released during the vulcanization process. It is widely used in silicone rubber processing industries.

FAQ

Q1: Why does silicone rubber require secondary vulcanization drying?

A1:After primary vulcanization, silicone rubber still contains certain residual low-molecular substances and initiators. Secondary vulcanization further improves cross-linking, eliminates product odors, and significantly enhances tensile strength and aging resistance.

Q2: What type of conveyor belt is commonly used for silicone rubber drying?

A2:Stainless steel mesh belts and Teflon mesh belts are commonly used. Stainless steel mesh belts provide excellent high-temperature resistance and long service life, making them suitable for heavier products. Teflon mesh belts have a smooth, non-stick surface, making them ideal for small silicone rubber parts with strict surface quality requirements.

Q3: How are volatile substances and odors generated during drying treated?

A3:The equipment is designed with an independent exhaust duct and powerful exhaust fan on the top of the oven. Volatile gases are collected and discharged through the factory exhaust treatment system for filtration and safe release.

Q4: Can each section of the tunnel oven have independent temperature control?

A4:Yes. The equipment adopts a multi-zone independent temperature control design. Each zone is equipped with an independent heating system, temperature sensor, and control instrument, allowing flexible adjustment of different process parameters.

Q5: How does the equipment ensure uniform temperature during large-scale silicone rubber drying?

A5:The system uses high-efficiency circulation fans installed on both sides, combined with professionally designed side and top air outlets. This creates strong horizontal or vertical airflow circulation inside the tunnel, ensuring uniform heating of products across the entire conveyor surface.
