Advantages of Vacuum Pyrolysis Cleaning Ovens

■  Thorough Cleaning: ensure thorough cleaning of objects, even in hard-to-reach areas or intricate shapes.

■  Versatility: can be used for a wide range of objects and materials.

■  Time and Cost Efficiency: automative operation and precise temperature control reduce cleaning time and increases productivity.

■  Environmentally Friendly: acuum pyrolysis cleaning utilizes heat and a low oxygen environment to remove contaminants, eliminating the need for harsh chemicals.

■  Safety: The low oxygen environment prevents combustion, reducing the likelihood of fire or explosions.

■  Improves Equipment Performance: by removing contaminants, vacuum pyrolysis cleaning helps improve the performance and longevity of equipment.

■  Low Maintenance: no need for frequent repairs or replacements, resulting in minimal downtime and cost savings.

Cleaning Process

Thermal decomposition of polypropylene plastics through vacuum pyrolysis

⒈Melt-off phase

The oven is heated to 300 degrees, and most of the polymers are melted off. The dirty material flows into the waste collection tank.

⒉Vacuum pyrolysis phase

The temperature is raised to 450 degrees (temperature depends on the material being cleaned), and the remaining polymers will continue to be decomposed under vacuum conditions.

3 Vacuum Oxidation phase

In the state with a small amount of air entering, the polymer is fully decomposed, and the generated gas will be pumped away.
