Do PET bottle flakes PET cleaning and crushing production meet the requirements of chemical fiber plants and bottle blowing plants

There are many cleaning manufacturers of PET bottle flakes, and the quality grades of the cleaned tablets are different. At present, the main manufacturers of PET bottle flakes are chemical fiber plants and preform factories. The requirements for the quality of bottle flakes are also different. There is no uniform standard, and the requirements and prices of different manufacturers vary. The following are the basic requirements for bottle flakes from general manufacturers in the industry for reference of PET bottle flakes washing manufacturers.

POY filament: the particle size is less than 12mm, the appearance is clean and translucent, no impurities are visible to the naked eye, no yellowing after baking at 210 ° for 30 minutes, and the PVC content is less than two ten thousandths;

Large chemical fiber: The particle size is less than 18mm, the appearance is clean and translucent, and no visible impurities are visible to the naked eye. Baking at 180 ° for 30 minutes does not cause yellowing, and the PVC content is less than five ten thousandths;

Small chemical fiber: The particle size is less than 18mm, the appearance is clean and translucent, no visible impurities, and no yellowing after 30 minutes baking at 180 °, and the PVC content is less than five ten thousandths; the appearance requirements are lower than that of large chemical fibers;

Preform factory :: The particle size is less than 10mm, the appearance is clean and translucent, and there are no visible impurities. It does not turn yellow after baking at 210 ° for 30 minutes, and the PVC content is less than two ten thousandths. The appearance requirements are lower than filaments.

At present, most washing material manufacturers can meet the requirements of chemical fiber factories in terms of particle size, appearance, and PVC content, but they are lacking in the indicator of yellowing at high temperature. The root cause is that caustic soda is used alone in the washing process ( Trisodium phosphate) causes excessive hydrolysis of the bottle flakes, so if you want to wash out qualified bottle flakes, it is best to choose a pet bottle flakes cleaning agent that does not turn yellow at high temperature.

How much do you know about PET bottle flakes cleaning and crushing production equipment?

1. Mineral water bottle washing machine
Unpacking machine → Conveyor → Drum screen → Pre-cleaning → Manual sorting table → Crushing → Rinse → Hot wash → High-speed friction wash → Dewatering → Pipe drying → Label separation → Packaging

What are the requirements for PET recycled pellets in chemical fiber plants and blow molding plants?

The viscosity of bottle pellets reaches about 0.65.

The viscosity of the regenerated particles of the cloth head is above 0.55,

PET powder recycled particle viscosity reaches 0.58-0.60

-Did you reach it?

2. Plastic granulation production line
Spiral feeding → Twin-screw extruder → Die / die head → Water tank (cooling function) → Drying → Pelletizing → Air feed silo (storage)

China Plastics Machinery Research Institute independently researched and developed a variety of waste plastic recycling equipment, mainly the development of cleaning and granulating machinery for waste plastics. Combined with European cleaning and granulation technology, the plastic recycling machine has local characteristics and high cost performance


Mineral water bottle recycling plastic cleaning and granulation production line includes unpacking, sorting, crushing, rinsing, separation, hot washing, dehydration, drying, label separation and other mineral water bottle cleaning lines and bottle pelletizing production lines. Bottle flake pelletizing production line includes equipment such as twin screw plastic extruder and draw bar pelletizing system.

In order to let our customers better understand the mineral water bottle recycling industry, this article mainly introduces the process of mineral water bottle cleaning line and the process of bottle pelletizer. By understanding these processes, users have a better experience with plastic cleaning and pelletizing opportunities.
