回收:塑料废品的升级回收

升级回收工艺将塑料变废为宝

塑料瓶以可回收材料的新身份,在电子设备、汽车或户外家具的生产中大量应用。这就是“升级回收”概念:回收料的性能经过优化,达到了与原生料品质相当的程度。

这个生产过程将塑料废品变成了未来市场上一种富有价值的原材料。  

凭借我们创新的技术解决方案,塑料可以被机械性地回收并重新使用,全过程不会有任何质量损失。 

首先要收集并对瓶料或工业生产的塑料废品进行分类。随后,物料被粉碎成瓶片进行清洗。 

科倍隆楷创的高精度喂料机将瓶片高效喂入科倍隆挤出机中。物料与添加剂、填料和增强材料一同被均化,脱挥并加工成与原生料品质相当的颗粒。回收料的性能满足后续使用要求。

我们可以明确地表示,对于塑料行业来说,循环经济是大势所趋,发展空间巨大

Jochen Schofer, 科倍隆回收和直接挤出事业部经理

Aurora Kunststoffe是一家位于德国Neuenstein的公司,2019年底成为MOL集团的成员,该公司正在展示如何利用科倍隆技术进行塑料废品的回收再造。这家复合材料生产商以塑料部件制造中积累的废弃料作为主要原材料,并将其回收加工成新的工业塑料产品。

每种通过质量管控的塑料被磨碎后喂入配混工艺段并切粒。Aurora Kunststoff依赖科倍隆ZSK技术实现了这一目标。在ZSK双螺杆挤出机内,破碎料与添加剂、填料和增强材料共混、均化并脱挥。

熔体经挤出机工艺段末端的机头排出后,料条由科倍隆造粒技术公司的半自动输送系统牵引,经过冷却水槽和下游的传送带自动输送到切粒机中,并被切割成高质量的粒子。

一步法“升级回收工艺

一项节能省时的强大创新技术:COREMA®将回收和配混的优点整合在同一个系统中,生产为高质量需求的应用所量身打造的回收料。 

经回收的原材料,如PP羊毛、PE边料、PA纤维,经强大的EREMA技术转化为熔体,过滤后直接送入科倍隆同向双螺杆挤出机。 

凭借其出色的配混和脱挥性能,这部分系统可以承担所有的生产要求。除了加入多种添加剂外,还可以添加大量的填料和增强剂。

Coperion ZSK twin screw extruder

双螺杆挤出机

科倍隆双螺杆挤出机是我们塑料回收工厂的核心,是将塑料瓶片转变成具有特定性能的粒料的理想设备,配混和脱挥性能显著高效。在真空排气和自然排气之外,熔体中的气体也可以通过ZS-EG侧向脱挥装置排出,从而提高产品质量。与产品接触的所有部件都采用了特殊的耐磨保护处理,确保了高质量生产的长期持续进行。 

切粒机

熔体在挤出机工艺段的末端通过机头挤出后,再进行拉条切粒。通过科倍隆切粒技术的自动或半自动线拉条切粒系统,可以实现该工艺步骤的自动化生产。料条经过冷却水槽和下游的传送带自动输送到切粒机中,并被切割成高质量的粒子。
