Mechanical recycling involves a mechanic process: you clean the plastic waste and you shred it with a shedder. You keep the molecular structure of the polymer (polymer is the scientific name of plastic). Mechanical recycling is a physical process. Chemical recycling is a chemical process: you u...
Chemical recycling is one of two major ways to recycle waste plastic. It splits polymer chains and creates products such as oil. The other way is mechanical recycling, which crushes waste to make new plastic products. 化学回收是回收废塑料的两种主要方法之一。它分裂聚合物链并产生诸如油之类的产品...
Recycling cycles cause a decrease in mechanical paper properties due to cellulose fiber degradation. The use of cellulose micro/nanofibers (CMF/CNF) to reinforce paper strength has been well studied, although it has been found to have negative effects on drainage. However, the application of CMF/...
Mechanical recycling refers to XPS foam recycling by compacting and granulating XPS foam into recycled particles. Waste XPS foam is first collected and sorted, and contaminants such as tape are cleaned. XPS foam needs to be compacted into tight foam ingots by a professional XPS densifier to imp...
Investments in chemical recycling are important for broadening the scope of recyclable feedstock by targeting those plastics and their specific applications that are not suitable for mechanical recycling.Mass balance is a method of bookkeeping to ensure proper allocation of input material in the final ...
The present disclosure describes an apparatus and a method for a chemical mechanical polishing (CMP) process that recycles used slurry as another slurry supply. The apparatus includes a pad on a rotation platen, a first feeder and a second feeder where each of the first and the second feeder ...
(> 95% purity) or significant addition of H2for the stream to be used for ammonia synthesis. The captured CO2can be recovered as pure CO2stream at the cost of energy input, either in the form of combustion of fuel, as illustrated in Fig.6B [44], or from mechanical work to switch ...
The crisis of plastic waste in the environment calls for new polymers that are designed specifically for recycling at the end of their life. Lignin, which is present in approximately 15–40% of woody biomass, is an attractive biobased source for polymers given its aromatic nature. However, the...
On the other hand, the elastic modulus and tensile strength of PA6/PC/ABS decreased with the number of recycling processes, whereas MFI, flexural properties, and impact strength of the ternary blends improved. 展开 关键词: PC/ABS PA6/PC/ABS polymer blends injection molding recycling mechanical ...
The majority of post-consumer plastic waste is not recycled. Impediments to the recycling of commodity polymers include separation, impurities and degradation of the macromolecular structures, all of which can negatively affect the properties of recycled
