Directly feeding unprocessed materials into the furnace will generate a large amount of smoke and fire, and all dust removal equipment cannot effectively treat them in the long term

We need a device to remove oil and paint from these secondary materials and preheat them before putting them into the furnace

What is paint stripping

Depainting is the process of removing paint, ink, paper, plastic, and oil from the surface of materials (usually metals) to improve recyclability. Traditionally, the substrate material is aluminum. Aluminum products now come in various forms, so they have various coatings. Some of the most common products are cans, extruders, lithographic materials, paint sidings, laminates, and chips. All coatings contain organic or inorganic compounds, and usually both. When released through thermal degradation or oxidation, they always undergo chemical changes because composite compounds are reduced to their basic forms. For example, polypropylene is reduced to carbon monoxide, carbon dioxide, hydrogen gas, and water vapor. It can be said that all products discharged during the paint stripping process, except for water vapor, are harmful to the environment.

UBC's recycling plan

 

Solution for dehydration and oil removal of aluminum shavings

Why do aluminum shavings need to be dehydrated and degreased

The main reasons or objectives include

The price of aluminum scrap can be increased by recycling and reusing the machining cutting fluid after separation, reducing wastewater treatment costs, lowering environmental pressure, aluminum scrap grade protection recycling, reducing costs, removing surface oil stains, and achieving higher recovery rates. Environmental protection emissions comply with occupational health and safety requirements, resource recycling, and carbon emissions are reduced
