PET 清洗线是塑料回收过程中的重要系统，专门设计用于清洁 PET 瓶并将其加工成高质量的 PET 薄片。

The Key To Producing High-Quality PET Flakes

生产高品质的PET瓶用树脂，需要从以下几个方面入手：

Use of High-Quality Raw M aterials

选择清洁、分类良好的PET瓶作为原材料是基础。尽量避免混入PVC、金属等其他杂质，影响PET瓶片的纯度。

Remove Impurities

配置高效分离设备。如塑料瓶标签去除器和浮沉式塑料分离器，可有效分离PVC标签和PP瓶盖。

Optimizing the Washing Process

采用先进的清洗机和合理的工艺，如热洗槽和摩擦清洗机，有效去除油污、粘合剂和标签残留物。

热洗时应严格控制洗涤温度和时间，以免破坏瓶片的特性粘度。另外，可以适量添加洗涤剂，有效去除顽固污渍和变色，但同时要注意保持pH值在合理范围内。

Use of High-Quality Drying Equipment

清洗后，通过高效离心脱水机和热风干燥装置，确保瓶片含水量低于0.5%，避免了后续加工过程中出现问题。

What is High-Quality PET Bottle Flakes?

高品质的PET瓶片通常具有以下特点：

• High purity: Contains very few impurities, especially PVC, PP, and PE with less than 0.01%.
• Good color transparency: the color of bottle flakes is close to that of virgin PET material, with no obvious signs of yellowing or contamination.
• Low water content: kept below 0.5% to ensure the stability of subsequent granulation or injection molding process.
• Uniformity of particle size: contributes to uniform heating and handling for subsequent processing.

How Much Does It Cost To Set Up a PET Washing Line?

PET清洗线的价格主要取决于产能、设备配置、自动化程度。通常，小型回收生产线的成本约为数万美元，大型塑料瓶清洗生产线的成本可能高达数十万美元。

What Equipment Is Included In A Complete PET Washing Line?

• Conveyor belt: feeding PET bottles into the washing line.
• PET bottle label removing machine: remove the label on the bottle.
• PET bottle crusher machine: crushes PET bottles into small flakes for subsequent cleaning.
• Float sink separator: removes light impurities such as caps and labels.
• Hot washed PET flakes machine: removes adhesives and oils with hot water and detergent.
• Friction washer machine: Friction washes away residual stains and cleaning agents.
• PET flakes dryer machine: Removes most of the water from the surface of the flakes.
• Air separation machine: further drying and removal of fine contaminants and labels.

The Role of High Quality PET Bottle Flakes

生产高质量的PET瓶片不仅可以提高市场竞争力，还可以满足广泛的工业需求。主要用途包括：

Production of recycled PET pellets: Used in the production of high-value-added products such as bottle blowing and injection molding.

Textile Industry: PET bottle flakes can be processed into polyester fibre for the manufacture of garments, carpets, etc.

Packaging Industry: Recycled PET bottle resins can be used in the production of food-grade packaging materials, reducing the use of virgin plastics.

Industrial Applications: Used in the industrial field for the production of plastic sheets, pipes and other products.

通过PET清洗线产出高品质的PET瓶片不仅可以为企业创造经济效益，还有助于环境保护的发展。
