Scrap metal market to the healthy development need to understand some of the drawbacks of scrap metal is lost value of the metal or alloy, although the loss of use value, but scrap metal containing metal can be reused after processing. This reduces the use of natural mineral resources. Resources are non-renewable resources are depleted as the world equipment recycling, scrap metal market and growth is inevitable. Scrap metal recycling bound to the world stage, but the scrap metal market, there are some drawbacks to some extent limit the development of the industry. Waste plastics recycling but a systematic project, to distinguish the various waste plastics, probably have to go buy some books on polymer materials! Guangzhou waste recycling companies here to make some simple introduction. Many of the specific classification of plastic on the polymer material, probably not be able to include a few words of recovery, but in terms of plastic, is available from the following classification: definition of thermosets and thermoplastics thermosets: polymer resin by the introduction of auxiliary heating plastics or plastics, after cooling and solidifying amorphous thermoplastic molding material can not, such as phenolics, urea-formaldehyde plastics, steel and plastic resins, etc. 191 again. Namely thermosets can not be recycled granulated again. Definition of thermoplastics: plasticized polymer resin by heating, cooling through stereotypes, can once again needed reheating PP materials recycled plastics molding, again and again. Plastic recycling granulation refers to this type of plastic. Thermoplastics can be divided further classified by conventional thermoplastic plastics and engineering plastics, GE Plastics commonly used thermoplastic polyethylene (PE) polypropylene (PP) Polyvinyl Chloride (PVC) polystyrene (PS), and so on, there are engineering plastics acrylonitrile - butadiene - styrene (ABS) high impact polystyrene (AS) or (HIPS).
