The basic process of UBC decoating process includes three main steps: pretreatment, paint stripping and post-treatment.
1. Pretreatment
The pretreatment stage mainly involves cleaning and sorting discarded cans. First, the cans are cleaned by high-pressure water guns or sandblasting machines to remove surface dirt and residues. Then, the cans are sorted according to their types and materials for subsequent paint stripping.
2. Paint stripping
Paint stripping is the core step of paint stripping of discarded cans. At this stage, professional paint stripping equipment, such as continuous can paint stripping and plastic stripping equipment, is required to carry out efficient and environmentally friendly paint stripping of cans.
The continuous can paint stripping and plastic stripping equipment uses advanced physical and chemical methods to quickly decompose and remove the coating on the surface of the cans through high temperature, high pressure, chemical solvents and other means. The equipment has the advantages of high automation, high processing efficiency, environmental protection and pollution-free, which can greatly improve the efficiency and quality of paint stripping of discarded cans.
During the paint stripping process, it is necessary to pay attention to controlling the paint stripping temperature, time and concentration of chemical solvents to ensure the paint stripping effect while avoiding damage to the can body. In addition, the waste liquid and waste gas generated during the paint stripping process need to be effectively treated to prevent harm to the environment and human health.
3. Post-processing
The post-processing stage mainly involves cleaning, drying and testing the cans after paint stripping. First, use clean water to thoroughly clean the cans after paint stripping to remove residual chemical solvents and coating fragments. Then, the cans are dried by drying equipment for subsequent recycling and reuse. Finally, the cans are quality tested to ensure that they meet the standards for recycling and reuse.
