Aluminum cans are not only lightweight, corrosion-resistant, and infinitely recyclable, but they also consume far less energy to recover aluminum than primary aluminum smelting. However, most beverage cans are covered with a layer of paint or printing coating, which, if left untreated, will seriously affect the quality of the aluminum to be smelted. Therefore, the paint removal process has become a key step in aluminum can recycling, and the UBC paint remover in the spotlight of this article is an important piece of equipment to solve this problem.

Working Principle of Thermal Paint Removal Furnace

The core device of the UBC paint remover is the Pyrolysis Furnace, the principle of which is to decompose and remove the coating on the surface of aluminum cans through high-temperature pyrolysis. Aluminum cans are heated to a set temperature (typically 450°C to 550°C) in a closed furnace chamber, which cracks the coating in an oxygen-free environment and turns it into a controlled gas or a trace residue, thus purifying the aluminum surface. The pyrolysis process does not destroy the structure and composition of the aluminum can itself, providing high-quality raw material for subsequent melting.

Advanced temperature control and heat recovery system

The modern UBC paint remover is equipped with an intelligent temperature control system that dynamically adjusts the furnace temperature according to the quantity of material to be processed and the thickness of the coating, effectively preventing overcooking or incomplete treatment. At the same time, the equipment integrates thermal energy recovery technology, which can reuse the hot gases released during the pyrolysis process for preheating new incoming materials or supplying energy to the furnace, significantly reducing the operating energy consumption. This heat energy recycling design not only saves energy but also reduces exhaust gas emissions and improves overall environmental protection.

Paint Removal Efficiency and Environmental Advantages

Compared with traditional chemical paint removal, thermal paint removers have significant advantages in terms of efficiency, environmental protection, and operational safety. High processing efficiency, capacity up to hundreds of kilograms per hour, and does not produce harmful waste water and strong corrosive residues, to adapt to modern green manufacturing needs. With compact structure and convenient maintenance, the equipment is widely used in aluminum processing enterprises, renewable resources companies, and metal recycling factories, and is an important equipment to promote the recycling of aluminum resources.
