PET-Flaschenwäsche- & Recyclingausrüstung Leitfaden | Rumtoo Machine

The plastics recycling sector continues to advance with significant enhancements in machinery and operational methodologies. PET bottle washing systems are integral to ensuring bottles are meticulously cleaned prior to recycling. Understanding the necessary machinery for an efficient PET bottle washing system is vital for recycling facilities aiming to optimize output and maintain product quality.

The core function of a PET bottle washing system is to thoroughly cleanse and prepare PET bottles for subsequent processing stages like re-pelletizing or direct reuse. This process eliminates contaminants, ensuring the plastic meets recycling standards.

Establishing an effective PET bottle washing system requires a clear understanding of the involved machinery and their synergistic operations. Standard systems incorporate components such as shredders, washers, friction washers, dryers, and separators, each contributing uniquely to the cleaning and preparation pipeline.

What is a Bottle Washing Recycling System Used For?

A bottle washing system is a foundational element in the recycling workflow, specifically engineered to clean PET bottles. But what are its precise applications? It guarantees that PET bottles are devoid of impurities like dirt, oils, labels, and adhesive remnants before further processing.

The principal objective of a bottle washing recycling system is the effective cleansing of PET bottles, eradicating all contaminants to produce high-quality recycled plastic. This system is essential for manufacturing cleaner, safer end-products from recycled materials.

A PET bottle washing recycling system is primarily employed to convert used PET bottles into viable raw material for new PET product manufacturing. This process is critical for preserving the recycled plastic’s value and ensuring it adheres to requisite reuse standards.

Shredding and Washing Process

An initial phase in the PET bottle washing system involves shredding bottles into smaller fragments. This facilitates handling and increases surface area for enhanced cleaning. Post-shredding, plastic pieces undergo multiple washing stages, utilizing methods like friction washing or soaking for thorough cleansing.

Decontamination of PET Bottles

The decontamination process is a pivotal aspect of the bottle washing system. Removing contaminants such as labels, adhesives, and other substances is necessary to safeguard the integrity of the new product. This ensures the recycled PET maintains high quality for its intended applications.

Which Washing Processes are Used for PET Bottles Recycling?

PET bottle recycling incorporates various washing processes to guarantee the plastic is pristine and ready for reuse. What specific washing techniques are commonly utilized? These encompass both mechanical and chemical washing methodologies.

In PET bottle recycling, the washing process entails the removal of contaminants like dirt, labels, and oils. Diverse mechanical and chemical methods are applied to ensure the final product is clean and free from impurities.

The washing process for PET bottles typically involves a combination of mechanical friction, hot water washing, and chemical treatments. These approaches effectively break down oils, inks, or adhesives on the plastic’s surface.

Mechanical Washing (Friction Washers)

Friction washers are crucial in the PET bottle washing process. These machines employ high-speed spinning to eliminate dirt, grease, and labels from bottles. The mechanical friction cleans the plastic without causing damage, rendering it suitable for subsequent recycling stages.

Hot Water and Chemical Wash

Following initial mechanical washing, hot water and chemical wash stages are often implemented to remove lingering contaminants. Chemicals such as detergents or caustic soda dissolve stubborn residues, ensuring the PET is comprehensively cleaned before advancing in the recycling pipeline.

What Chemical is Used to Wash PET Flakes?

Chemicals are instrumental in achieving a deep clean during the PET flakes washing process. But which specific chemicals are employed, and why are they efficacious in PET recycling?

Chemicals like caustic soda (sodium hydroxide) and detergents are routinely used to wash PET flakes. These substances break down tenacious residues such as oil, ink, and adhesives, preparing the flakes for reprocessing.

Caustic soda is among the most prevalent chemicals in PET recycling. It proficiently removes contaminants like oils, inks, and adhesives that are challenging to eradicate with water alone. However, careful application is necessary to prevent plastic degradation.

Detergents and Surfactants

Besides caustic soda, various detergents and surfactants may be utilized for washing PET flakes. These chemicals reduce water’s surface tension, simplifying contaminant removal from the plastic. They are also effective at dissolving sticky residues present on the PET.

What Other Types of Plastics are Available for PET Bottles?

While PET is the predominant plastic for bottles, other types are occasionally used in bottle production. These plastics are not always suitable for PET recycling and must be separated before the process continues.

Other plastics, such as HDPE (high-density polyethylene), PVC (polyvinyl chloride), and LDPE (low-density polyethylene), are sometimes utilized in bottle manufacturing. These require distinct processing and must be identified and removed during the PET bottle washing process.

HDPE, PVC, and LDPE are commonly found in bottles but possess different properties than PET. Consequently, they necessitate separate recycling processes and must be segregated to ensure only PET is included in the final recycled product.

Identification and Separation

Effective PET recycling hinges on identifying and separating disparate plastic types. This is typically accomplished through advanced sorting technologies like infrared sensors or air classification. These methods help isolate PET from other plastics in the bottle waste stream.

How to Separate Other Types of Plastics in PET Bottles from PET?

Separating different plastics in PET bottles is a crucial recycling step. This ensures only PET is incorporated into the final product, preventing contamination from other plastics that require different processing.

The separation of different plastics in PET bottles is achieved via various sorting technologies. Methods like air classification, density separation, and optical sorting ensure PET is isolated from materials like HDPE, PVC, and LDPE.

Advanced sorting technologies, such as optical sorters and air classifiers, are essential in the separation process. Optical sorters use light and sensors to identify different plastics, while air classifiers leverage density differences to separate PET from other materials.

Density Separation

Density separation is one of the most effective methods for plastic segregation. This technique capitalizes on the varying densities of different plastics. PET, for instance, has a higher density than HDPE, allowing easy separation in a water-based bath where lower-density plastics like HDPE float, and PET sinks.
