PET常用于制造饮料瓶、试剂瓶、纤维等,是最常见的塑料之一,具有很高的利用和回收价值。然而,回收和清洗塑料瓶也面临一些挑战。在这篇文章中,我们将分析PET瓶片清洗过程中可能遇到的困难以及如何解决这些困难。

多种污染物使清洗变得困难

塑料瓶常用的有饮料瓶、油瓶、化学测试瓶等,因此收集到的PET塑料瓶中混有油类、化学试剂等多种污染物。面对这些不同类型的污染物,通过单一的清洗工艺不可能实现彻底的清洗。

Action: We have developed a three-step PET flakes washing method. First, we utilize a friction washing machine to eliminate surface stains, such as dirt. Next, we employ a plastic sink float tank to separate contaminants based on their density. Finally, we use a hot washer washing machine to dissolve any remaining contaminants like oil, and glue at high temperatures, ensuring a thorough cleaning process.

杂质影响 pET 瓶的清洁度

贴在PET瓶上的PVC标签不易去除,这将导致后续加热工作中PET碎片的热解释;其次,胶水或其他化学残留物会影响清洁效果。

Action: Using a de-labeling machine before washing can remove more than 98% of the label, reducing the difficulty of subsequent washing and improving the purity of recycled PET. In addition, a detergent can be added to the hot wash process to help clean the plastic bottle pieces

塑料洗衣机的堵塞

塑料瓶清洗过程中,标签、沉积物和其他杂质可能会堵塞机器,导致清洗效率降低甚至停机。因此,需要注意每个清洗阶段过滤器的安装以及每台塑料清洗机排料口的及时检查和疏通。

Measures: You can choose an anti-clogging design for your PET flakes washing machine. Our plastic bottle washing line is equipped with a trommel separator and other impurity filtration devices, which are efficient, convenient, and not easy to jam!

清洁成本较高

清洗 PET 瓶会消耗大量的水和能源,特别是在热洗和漂洗阶段。因此,选择节能环保的设备非常重要。

Suggestion: It is recommended to choose a site with abundant water resources for washing and equipped with a water recycling system to reduce water consumption. On the other hand, before discharging the sewage, introduce a sewage treatment system to ensure that the pollutants meet the environmental requirements.

结论

PET瓶片清洗关系到再生PET的纯度和质量。面对这些挑战,我们需要选择合适的设备来帮助彻底去除杂质并提高再生PET的质量。如果您对塑料瓶回收清洗还有任何疑问,请联系我们,我们将为您规划合适的塑料瓶清洗解决方案!
