Koji koraci osiguravaju čiste, višekratno upotrebljive PET pahuljice?

In the realm of plastic recycling, the demand for clean, high-quality PET flakes is on the rise, especially across the United States and Europe. As manufacturers and industrial recycling equipment purchasers seek reliable solutions, Rumtoo Machine has established itself as a trusted provider of cutting-edge recycling systems. A fundamental process at the core of this industry involves converting used PET bottles into clean, reusable flakes.

This article delineates the critical steps required to ensure PET flakes are free from contaminants and ready for reuse in new products, adhering to international quality standards.

1. Efficient Collection and Sorting

The journey to obtaining clean PET flakes commences with proper collection and sorting. Bottles must be segregated by material type, color, and degree of contamination. Manual or automated sorting systems can identify and isolate PET materials from other plastics, metals, and non-recyclables. Advanced optical sorters, now widely employed in modern recycling plants powered by Rumtoo Machine, significantly enhance the accuracy of this stage.

2. Label and Cap Removal

Labels, caps, and rings are generally made from materials other than PET (such as PP or HDPE). Their removal is crucial, as these impurities can compromise the integrity of the final flakes. De-labelling machines and pre-wash systems assist in separating these elements before the bottles enter the main washing line.

3. Pre-Washing and Crushing

The PET bottles then undergo a pre-washing phase to remove surface dirt, residues, and glue. Subsequently, they are mechanically shredded into smaller flakes. At this stage, the uniformity of particle size plays a pivotal role in the subsequent cleaning and drying efficiency. Rumtoo Machine’s PET bottle washing line ensures high throughput and minimal loss during this phase.

4. Hot Washing Process

Hot washing is essential for dissolving sticky contaminants such as glue, oil, and food residues. Utilizing heated alkaline solutions, this step ensures that any residual labels or adhesives are removed, yielding flakes of superior clarity and cleanliness. Rumtoo Machine integrates precise temperature control and agitation in its washing lines to optimize cleaning performance.

5. Friction Washing and Rinsing

Following the hot-wash, the flakes are subjected to high-speed friction washing. This mechanical action, combined with water flow, scrubs the flakes clean. The rinsing stage follows, which ensures all chemical and dirt residues are eliminated. The use of clean, filtered water in Rumtoo Machine systems guarantees that no recontamination occurs.

6. Drying and Final Separation

The cleaned flakes are then dried using high-efficiency centrifugal or thermal drying systems. Final separation techniques, such as air classification and float-sink tanks, assist in removing any remaining contaminants like fine paper or mixed plastic residues. This results in premium-grade PET flakes suitable for a variety of reprocessing applications.

7. Quality Control and Testing

Consistent quality control is imperative. Periodic testing of the flakes for intrinsic viscosity (IV) value, clarity, contamination level, and physical properties ensures compliance with regulatory and market demands. Rumtoo Machine offers integrated quality monitoring systems, providing real-time feedback and traceability.

FAQs: Clean, Reusable PET Flakes

Q1: Why is hot washing necessary in PET recycling?
Hot washing removes tenacious adhesives, labels, and food residues that cold washing cannot dissolve effectively, ensuring cleaner PET flakes.

Q2: Can your PET flakes be used for food-grade packaging?
Yes, when processed under stringent hygiene and regulatory conditions, the PET flakes produced can meet FDA and EFSA standards for food-contact materials.

Q3: What makes Rumtoo Machine’s washing line stand out?
Our systems are engineered with precision, automated quality control, and high-throughput capabilities, ensuring consistent, industry-grade performance.
