På den snabba återvinningsmarknaden för skrot har aluminium länge ockuperat en viktig position med sina överlägsna egenskaper såsom lätthet, korrosionsbeständighet och hög värmeledningsförmåga .
1. Aluminiums unika charm
Aluminum has become an indispensable material for industry, construction, and electronic products due to its low density and high strength. The latest industry data shows that the recycling rate of aluminum has exceeded 85%, which not only effectively reduces production costs, but also contributes to environmental protection. It is these advantages that make recycled aluminum extremely valuable in the scrap Market .
2. Vanliga aluminiumtyper och applikationsområden
1. Aluminiumplattor används ofta i hushållsapparater, bildelar och arkitektonisk dekoration . När återvinning av aluminiumplattor av olika tjocklekar är klassificeringsstandarderna strikta, vilket är direkt relaterat till kvaliteten och priset för återvinningsresurser .}}}}}}}}}}}}}}}}}}}}}}
2. Products such as aluminum bars and aluminum tubes usually play a key role in mechanical manufacturing and aerospace. Their stable physical properties make scrap aluminum bars and aluminum tubes very popular in the recycling market. Many recyclers have reported that the recycling ratio of aluminum tubes has steadily increased in recent år .
Aluminiumprofiler Aluminiumprofiler som formas genom extrudering har olika former och används i stor utsträckning i dörrar, fönster, gardinväggar och industrinutrustning. Enligt branschstatistik står aluminiumprofiler för nästan 40% av den totala återvinningsvolymen, och deras komplexa ytbehandlingsprocess ställer högre krav på återvinningsprocessen.
4. Aluminum alloy grades and recycling value Aluminum alloys of different grades perform differently in recycling. For example: 1100 series: known for its high purity and good formability, commonly used in thin and light products. 5052 and 6061 series: have good corrosion resistance and mechanical strength, and are popular choices for manufacturing structural parts. 7075 series: Despite its outstanding strength, due to its low corrosion resistance, special attention should be paid to the processing process during recycling. Each grade not only determines the use of the product, but also directly affects the economic value and processing difficulty of waste recycling. Professional recycling masters often adopt different sorting and pretreatment strategies according to the characteristics av materialet för att säkerställa kvaliteten och marknadskonkurrensen för återvunnet aluminium .
3. Påverkan av ytteknologi på återvinning
Anodizing, electrophoretic painting, sandblasting and wire drawing processes improve the appearance and durability of products, but also increase the difficulty of handling waste during recycling. There are many cases in the industry where the residual adhesion layer has been successfully reduced by improving pretreatment technology, which not only improves recycling efficiency, but also brings more high-quality raw materials to the recycling industri .
