CCP PVB B-06HX

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, Polyvinyl Butyral Resin (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 (PVB SD-4 & PVB B-03HX) 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

PVB (Polyvinyl Butyral) is a synthetic resin, which is the product of the acid-catalyzed condensation of polyvinyl alcohol and butyraldehyde. It has many features and a wide range of applications. PVB molecules contain long branch chains, have good flexibility, low glass transition temperature, and high tensile strength and impact strength. PVB resin has good thermal bonding properties and can be connected to other materials through hot pressing or hot melting methods. It has excellent transparency, good solubility, good light resistance, water resistance, heat resistance, cold resistance and film-forming properties.   PVB resin has good weather resistance against ultraviolet radiation and atmospheric oxidation, and can provide long-term protection. Bonds well to glass and other materials. This makes PVB film an important material for manufacturing laminated glass, which can enhance the impact resistance and safety of the glass. This safety glass has good transparency and high impact strength, and is widely used in the aviation and automotive fields.   Because PVB resin has good transparency and optical properties, it is a transparent material with a high refractive index and low hygroscopicity. It is widely used in fields such as optical coatings, optical films and optical glasses.   PVB ( PVB SD-6 & PVB B-18HX) can also be used for flexo printing, gravure printing, embossing printing, screen printing, and thermal transfer printing in the printing industry. Because it is soluble in alcohol and non-toxic, the printed parts do not retain odor, and can be used in packaging that is sensitive to odor in the food industry. Such as tea/cigarettes, etc. Because the resin is cationic, it has adhesion to glass surfaces with strong anions, and is especially suitable for glass plate decorative silk screen printing.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
