TECHNICAL FIELD
[0001] The utility model relates to the field of waste PET polyester sheet recycling, especially a waste polyester sheet melting device. BACKGROUND
[0002] PET is the abbreviation of polyethylene terephthalate, which is a high polymer, and is obtained by the dehydration condensation reaction of polyethylene terephthalate. Polyethylene terephthalate is obtained by the esterification reaction of terephthalic acid and ethylene glycol. Polyester sheet is a polymer obtained by polycondensation of polyol and polyacid. It mainly refers to polyethylene terephthalate, and also includes polybutylene terephthalate and polyarylate linear thermoplastic resin. It is an engineering plastic with excellent performance and wide application, and can also be made into polyester fiber and polyester sheet.
[0003] With the development of social economy and the improvement of people's living standards, polyester products have become the preferred material for packaging and consumer goods due to their lightness, durability, transparency and other advantages. The demand in the fields of beverage bottles, food packaging, textiles and other fields is growing, leading to an increasing consumption of polyester materials year by year. However, these products are often discarded after use, resulting in a large amount of waste polyester sheet. In addition, the one-time use of polyester products also exacerbates the generation of waste polyester sheet. Therefore, recycling of waste polyester sheet is a necessary means to realize the recycling of resources. Recycling of waste polyester sheet can promote the development of circular economy and realize sustainable use of resources, which helps to reduce carbon emissions.
[0004] Melting is a key step in recycling waste polyester sheet. By melting and reshaping waste polyester sheet, recycling and utilization are realized. Melting refers to the process of increasing the kinetic energy of molecular thermal motion when the temperature rises, leading to the destruction of crystallization, and the change of matter from crystal phase to liquid phase, which is a first-order phase transition with an increase in enthalpy, entropy and volume. The waste polyester sheet is processed by melting device. The current waste polyester sheet melting device is derived from different products, so the shape and size of the waste polyester sheet are different, which increases the melting difficulty of waste polyester sheet recycling. If the polyester sheet with different shapes and sizes cannot be compatible, the recycling efficiency of waste polyester sheet will be reduced. Therefore, we propose a waste polyester sheet melting device to solve the above problems. Utility model content
