In recent years, with the accelerated pace of urbanization in my country and the continuous growth of automobile sales, there has been a strong demand for PVB laminated glass. At the same time, with the development of technology, PVB Film has been researched and developed, and the application market has been further developed. In this development process, we must not only pay attention to new technological innovation, but also overcome the technical difficulties in the process of PVB waste collection and recycling, so as to achieve the environmental friendliness and maximize the economic benefits of the PVB industry. At present, the recycling of PVB resin mainly includes physical recycling method, chemical recycling method and energy recovery method.   Physical recycling is to put the discarded PVB through a series of physical treatment processes, such as separation, purification, cleaning, etc., and at the same time, add certain additives as required for reuse. This method can effectively utilize PVB materials and greatly reduce environmental pollution. For example, the PVB solid waste and scraps discarded in the market are recycled, and after sorting, cleaning, drying, and crushing processes, plasticizers, tougheners, three-salt stabilizers and other additives are added, and waterproof membranes for construction are produced through high-speed mixing, mastication, tableting and other processes. Through experimental research, it has been found that the waterproof membrane has good mechanical properties, convenient processing, and a wide operating temperature range, and has broad market prospects in the construction field.   The chemical recycling method uses light, heat, radiation, and chemical reagents to degrade PVB polymer into low-molecular single or hydrocarbon substances. At the same time, the cracked raw materials can be reused. Common cracking methods include hydrolysis, alcoholysis, thermal cracking, hydrocracking, catalytic cracking, etc. However, the current technology of this deep chemical recovery method is not very mature, the technology cost is high, and the economic benefits are low. Currently, the most commonly used method is to process waste PVB to obtain pure polymer resins and additives. Supercritical separation technology is used to separate the additives and resin in colorless PVB.   Energy recovery is the process of extracting energy from waste plastic, typically used as fuel or to generate steam to generate electricity. Because PVB polymer contains a large amount of hydrocarbons, it is flammable. Although the energy recovery method is one of the methods for recycling PVB waste, it is not commonly used due to its high cost.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
