[China Packaging News] PVC recycled materials have the characteristics of high mechanical strength, light weight, insulation performance, high strength, easy processing, corrosion resistance and so on. It is widely used in various fields, such as construction, pipe, electronic and electrical appliances, automotive industry, packaging and other fields

The application of PVC recycled materials has great advantages, especially in the field of pipes. PVC plastic pipes processed with PVC recycled materials are mainly used in the construction industry to replace traditional cast iron pipes to make indoor and outdoor drainage pipes, wire threading pipes and communication cable protection pipes

pvc pipe regeneration is tested according to SAE j1960 standard (energy 2500 kj/m2) recycling technology of materials

PVC recycled materials obtained from extrusion regeneration of waste PVC pipes are often used to make wire sheaths for circuit laying in buildings, which are required not to collapse when heated and bent

generally, rigid PVC waste pipe materials contain impact modifiers and other modifiers, so their elongation at break and impact strength are better than that of pipe grade PVC raw material resin, but their fluidity is poor. When extruding and regenerating, appropriately adding a certain amount of new resin or other rigid PVC waste products with less filling is helpful to improve the melting fluidity of recycled materials, and at the same time, adding an appropriate amount of stabilizer, To reduce the degradation of PVC during reprocessing and use

compared with the pipes made of new PVC raw materials, the impact resistance of the pipes made in this way is improved, and other physical properties have no obvious changes

soft PVC pipe materials need to be used in combination with hard pipe materials, or other inorganic fillers should be added at the end of production to ensure that its processing energy and use performance meet the use

pvc pipe recycled material 6. The open data structure allows users to randomly call whether the result parameters or process data, which is very beneficial to scientific research and teaching. Precautions for use

plastic pipe after regeneration processing, the performance decreases to varying degrees, mainly caused by light aging, oxidation and heat aging. The degree of performance degradation mainly depends on the service life and environment

waste edges and waste products produced in the production of molding processing plant. The performance of the recycled material decreases very little, and it can almost be used as new material; For products used indoors and with short service life, the performance of recycled materials also changes little; In outdoor use, products with long service life and poor environment (such as under pressure, electric field, chemical medium, etc.) have poor performance, and even cannot be recycled

during regeneration, PVC is degraded by thermal aging, and the color of recycled material changes from light to dark, according to the data. It is not recommended to mix or directly use recycled materials for industrial plastic products and pipes
