PET (polyethylene terephthalate) has a wide range of product varieties, including polyester staple fiber, polyester filament, PET polyester plastic bottle, PET polyester film, PET non-woven fabric, engineering plastics and composite versatility There are hundreds of products and thousands of specifications in many series. Due to the continuous increase in social demand, the production of PET polyester has grown rapidly. At present, most PET products are disposable consumer goods, which results in a large amount of waste PET materials. This material is chemically inert and will not be easily degraded by air or microorganisms in a short time, occupying a large amount of space and causing "white pollution". The current task of protecting the ecological environment is urgent. The recycling of waste PET materials is of great benefit to environmental protection, resource conservation and sustainable development. The recycling of waste PET beverage bottles can not only reduce environmental pollution, but also turn waste into treasure and obtain huge economic benefits from it. With the popularity of non-fiber PET and other packaging products, PET recycling and reprocessing technologies have emerged in large numbers.
However, the current market for the recycling of PET materials is mainly limited to materials such as bottles and films, and there is no report on the recycling of fiber fluff made of PET. PET fiber wool is mainly used in carpets, blankets, woolen coats, etc. However, a large amount of leftovers and tailings are produced during the preparation process. These leftovers and tailings are relatively clean, but cannot be directly reused. With the substantial increase in the amount, the waste of PET fiber felt has become a waste that cannot be ignored. Recycling it can not only reduce environmental pollution, but also obtain huge economic benefits and turn it into treasure.
1. Picture of PET chemical fiber filament receiving granulator
This equipment adopts ML crushing, extruding and granulating integrated machine. Strand and diced. Output: 120-1200kg
Working principle: belt conveyor-crusher-belt conveyor-chamber machine crushing again-extruder-screen change-die-cooling-pelletizing-drying-silo
2. Picture of PET bottle flake granulator
The equipment adopts TSSK twin-screw main engine, screw feeding, stranding and pelletizing, and the output is 120-1200kg
Working principle: PET bottle flakes → screw feeding → feeder → twin screw extruder → PET vacuum system → hydraulic change → granulation → air delivery system → silo storage
3. Picture of PET cloth head recycling granulator
This equipment is similar to PET chemical fiber equipment, using ML series crushing, extruding and pelletizing integrated machine. Stranding and pelletizing, the output is 120-1200kg
Working principle: PET cloth head→belt conveyor→closed chamber machine→twin screw extruder→PET vacuum system→hydraulic screen changing→stretch die head→water ring cooling→drying→granulator→air conveying system→silo storage
