Can paint removal technology is mainly divided into mechanical paint removal, chemical paint removal and carbonization pyrolysis paint removal methods.
1. Mechanical paint removal: use mechanical tools such as grinding wheel, spatula, wire brush, etc. to polish or scrape off the paint layer on the surface of cans. This method does not require the use of chemicals, but may be less efficient and requires manual operation. 2.
2. chemical paint stripping: the use of solvents, acids and alkalis and other chemicals, the surface of the cans will be dissolved or corrosion of the paint layer. This method is highly efficient and suitable for large-scale paint stripping, but need to pay attention to safety, to avoid chemical damage to the human body.
3. Carbonization and pyrolysis paint removal: the cans are first crushed, and then preheated and heated by a continuous carbonization furnace, so that the coating can be pyrolyzed in an oxygen-free and high-temperature environment, thus removing the paint layer. This method is environmentally friendly and efficient, can avoid the use of chemicals, reduce environmental pollution.
Jiu Tian Machinery is a professional manufacturer of continuous carbonization furnace and other advanced equipment, carbonization furnace to cans paint is a pyrolytic way to remove paint, through the dry distillation in an oxygen-free high-temperature environment to achieve paint removal paint, does not produce wastewater, exhaust gas after exhaust gas treatment and discharge, which can be in line with environmental requirements.
The process flow of paint removal in Jiu Tian machinery canister charring furnace:
- Preheating stage: Preheat the continuous carbonization furnace to the temperature of aluminum can pyrolysis (about 500 degrees).
- Feeding stage: Start feeding after starting the equipment, make sure the feeding port is sealed to prevent heat dissipation.
- Pyrolysis Stage: The can pieces undergo a high temperature pyrolysis reaction in the furnace and the paint layer is removed by pyrolysis. This process takes about 20-30 minutes.
- Discharge stage: The can fragments after paint removal are discharged from the discharge port and cooled down by water cooling device.
Jiu Tian Machinery has achieved the goal of environmentally friendly and efficient paint removal by selecting advanced equipment, optimizing the process and implementing environmental protection measures in the can paint removal process. This practice not only improves the recycling rate of cans, but also reduces environmental pollution, in line with the requirements of sustainable development.
