铝是地球上使用次数最多的金属，也是生产中使用最广泛的金属饮料罐。对于将金属用于各种目的的消费者公司来说，铝产品的需求量很大，例如食品包装，药品包装，电力传输，海运，电子和建筑工艺。这使得铝成为高价值的金属。除了对现代生活方式的积极影响外，铝具有高废料价值，并且回收利用的能源成本非常低。为此，许多人优选其便利性和可回收性。使用过的饮料罐占铝合金的大部分用于回收的废料，约占所有废料的37％。到2020年，全球铝的稳定增长预计将达到7000万吨。这种需求水平意味着回收过程必须高效，节能且成本降低。

铝回收的起源
铝回收的做法不是一个新的概念。这是20世纪初的常见做法，在第二次世界大战期间尤为普遍。然而，直到20世纪60年代，饮料罐变得流行，回收的想法成为公众的主流。 铝回收的主要优点是这很便宜，可以多次无损回收。饮料罐目前是再生铝的主要来源。再生铝的其他来源包括汽车，飞机，炊具，计算机，自行车和船只。铝被认为是一种高价值的金属，因为它具有强大的轻质特性和高导热性。此外，在回收过程中，它不会失去质量或转化为另一个元素。它仍然是纯粹的形式。

为了开始铝回收过程，从垃圾收集中心，家庭和街道收集废料。这些可以是饮用罐，气溶胶，铝箔和其他铝制产品。然后将废铝用于铝处理厂的分选。
[/fusion_toggle][fusion_toggle title=”排序” open=”no”]
由于收集的物品是钢罐和铝罐的混合物，因此进行分选以分离金属。第二步对于确保整个过程成功至关重要，因为一些饮料罐由钢制成。收集的材料通过回收设备，该设备分离不同的金属流：铝和钢。然后将它们压缩并分开放置。[/fusion_toggle][/fusion_accordion][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”no” hundred_percent_height=”no” hundred_percent_height_scroll=”no” hundred_percent_height_center_content=”yes” equal_height_columns=”no” menu_anchor=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”center center” background_repeat=”no-repeat” fade=”no” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ video_mp4=”” video_webm=”” video_ogv=”” video_url=”” video_aspect_ratio=”16:9″ video_loop=”yes” video_mute=”yes” video_preview_image=”” border_size=”” border_color=”” border_style=”solid” margin_top=”” margin_bottom=”” padding_top=”” padding_right=”” padding_bottom=”” padding_left=””][fusion_builder_row][fusion_builder_column type=”1_1″ layout=”1_1″ spacing=”” center_content=”no” link=”” target=”_self” min_height=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” background_color=”” background_image=”” background_position=”left top” background_repeat=”no-repeat” hover_type=”none” border_size=”0″ border_color=”” border_style=”solid” border_position=”all” padding_top=”” padding_right=”” padding_bottom=”” padding_left=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” last=”no”][fusion_text columns=”” column_min_width=”” column_spacing=”” rule_style=”default” rule_size=”” rule_color=”” class=”” id=””]

下一阶段 铝回收涉及粉碎。分拣完成后，铝块进入下一阶段进行处理。这里，块通过传送带，在那里它们被引导到切碎机。碎纸机将铝撕成小块。这对于摆脱以前的着色和装饰很重要 铝。此外，切碎使熔化炉中的金属更容易。为了进一步确保铝中没有钢的痕迹，切碎的碎片通过磁铁。钢是磁性的，因此任何痕迹都会被磁铁吸引。该过程确保再生铝符合所需的质量标准。
[/fusion_li_item][fusion_li_item icon=””]
切碎的碎片通过使用传送系统的专用去涂器。这个过程分离了碎铝上的任何装饰和颜色。非常热的空气吹过碎片，装饰和颜色蒸发并变成气态。去除并清洁罐上的油漆，涂料和油墨。
[/fusion_li_item][fusion_li_item icon=””]
将脱涂的碎片送入加热至700℃的炉中，这是大多数金属的最低熔点。铝在此温度下熔化。在此阶段，将某些化学品添加到熔融铝中。这有助于为下一阶段实现正确的化学成分。熔融铝中的任何杂质漂浮在表面上，使用专门的刮削工具可以容易地除去。
[/fusion_li_item][fusion_li_item icon=””]
然后将熔融铝在保温炉中转变成锭。锭是纯铝块，铸造成合适的形状以备进一步加工。保温炉倾斜以将熔融金属倒入块中。单个铸锭可由约160万个铝罐组成。
[/fusion_li_item][fusion_li_item icon=””]
然后使用高架起重机将铸锭从铸造坑中提起并装载到准备运输到轧机上的轨道上。一旦进入轧机，就将它们轧成铝板，厚度约为1/100英寸。然后这些薄板可供罐头制造商使用。在五个星期的时间内，再生铝已经在您的商店和超市的货架上。然后重复该过程，同时铝的质量损失最小。

铝回收的好处
自20世纪之交以来，铝回收的实践已经存在。与氧化铝的电解相反，它已被证明是一种获得纯铝的成本有效方法。回收过程节省了通过电解获得新铝所需的约95％的能量。因此，它对整个环境来说是容易和有益的。以下是铝回收的其他一些优点。

再生铝仅使用通过电解从铝土矿中获得新铝所需能量的5％。这是一种具有成本效益的方法，可显着节约能源。

保持地壳中铝的供应。由于铝以铝土矿的形式存在于地壳中，因此回收减少了采矿的需要。这确保了铝的连续供应以备将来使用。
[/fusion_li_item][fusion_li_item icon=””]
铝可以无限循环使用而不会损失其质量或磨损。这种无损的铝质意味着它可以无数次地重复使用和回收。因此，消费者公司和汽车制造商更喜欢铝，因为它提供了一种具有成本效益的选择。

铝回收减少了垃圾填埋和废物。许多国家已经为垃圾场挖了大量垃圾填埋场 废物管理。铝制饮料罐是主要的 垃圾 材料 垃圾填埋场的。通过回收这些饮用罐，减少了垃圾填埋场的扩散。这进一步防止了严重的环境危害 垃圾和垃圾填埋场，如有毒排放。

由于对铝包装的需求不断增加，回收饮料罐提供了便宜且对环境有益的便利解决方案。回收过程比通过采矿和电解铝土矿获得铝便宜得多。
