What else can the PET beverage bottle throw away after drinking?
There are two main methods for recycling PET waste. One method is to use degradation methods to recover monomer terephthalic acid and ethylene glycol, or to add organic solvents and additives to produce floor coatings, adhesives and lubricants, etc. . For example, alcoholysis of PET recycled material, and then adding dibasic acid anhydride to polycondensation to a certain acid value, diluting, filtering, and adding an appropriate amount of catalyst to obtain alkyd resin paint, which has good adhesion, acid, alkali, and waterproof It can be used as ground coating.
The other method is to directly regenerate and plasticize PET recycled materials or prepare modified recycled materials through blending and modification. For example, the recycled PET plastic bottles are washed, separated, dried and then pelletized. It can be used to prepare non-food containers, accessories, fibers, etc.
When it comes to fiber, someone may ask: PET raw materials can be spun, can the recycled PET mineral water bottles be spun to make fibers? This is really ok. At the end of the last century, the world's annual consumption of PET used in the fiber industry was about 11.4 million tons, accounting for 70% of the world's total PET production. The recycled PET is finally spun into polyester yarn and woven into polyester fiber fabric through processes such as separation, cleaning, crushing, drying, plasticization, stranding, and carding.
In addition to preparing polyester fiber fabrics, recycled PET can also be used to make non-woven fabrics, which is a product that applies new spinning technology. At present, the use of non-woven shopping bags instead of disposable plastic bags is strongly advocated to reduce the amount of plastic waste. In fact, PET non-woven fabric is also a kind of plastic. Therefore, I hope everyone can recycle non-woven shopping bags. In addition, recycled PET can also be used for spinning to make carpets. It can be seen that there are many ways to recycle PET.
The recycling of plastic bottles can effectively reduce the solid waste in the environment, save energy and protect the environment. Garbage recycling is the basis for garbage sorting, processing and utilization. Good garbage collection is of great significance.
