1. Brief introduction of PET plastic PET plastic is the abbreviation of English Polyethylene terephthalate, referred to as PET or PETP. Chinese meaning: polyethylene terephthalate plastics, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT. Polyethylene terephthalate is also commonly known as polyester resin, commonly known as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET recycled plastic can be used in food packaging, which can achieve infinite recycling. This is my country's accessible environmental protection technology. Since the raw materials of plastic packaging come from petroleum, in order to save resources, many developed countries have developed recycling technologies for plastic packaging. As early as 1991, recycled PET plastic slices have been used as food packaging materials. 2. The development status of PET plastics in my country At present, the packaging containers of polyester pet plastics in my country are mainly limited to biaxially oriented polyester blow-molded bottles. Therefore, the following mainly introduces the development status of my country's PET plastics from the development of my country's PET bottles, and lists two leading groups in the PET bottle production industry. my country's biaxially stretched polyester blow molding bottle started late in the plastic packaging industry, but since the introduction of the injection stretch blow PET bottle production line from Japan in the 1980s, it has achieved good results in beverage packaging represented by cola , and then introduced a large number of foreign advanced injection stretch blow molding PET bottle production equipment, and on the basis of digesting foreign advanced technology, developed a two-step PET stretch blow molding machine with independent intellectual property rights, suitable for my country's national conditions, and simple structure , It is used in conjunction with the universal injection machine to blow the PET biaxially stretched bottle using the PET preform made by the universal injection machine. Among the domestic two-step biaxially oriented PET blow molding machines, some models can not only produce ordinary PET biaxially oriented bottles, but also heat-resistant biaxially oriented PET bottles. The volume of the products that can be produced basically covers Imported equipment can produce a vast field from tens of milliliter vials to 5 gallon vats. These simple blow molding machines not only have the advantages of low cost and strong maneuverability, but also can produce biaxially oriented PET blowing bottles with high quality and good practicability when properly controlled. Therefore, they have been generally recognized by the plastic processing industry at home and abroad. In addition to a large number of domestic use, some of them have been exported. Although there are still gaps between these equipment and imported advanced equipment, such as low production efficiency, poor degree of automation, and poor dimensional accuracy of products, there are still certain difficulties in their application in some application fields with particularly strict requirements. In addition, the production equipment for multi-layer co-blown PET bottles has yet to be developed in China, but the development and utilization of the domestic two-step biaxially oriented PET bottle blowing machine has played a huge role in promoting the rapid development of PET bottle production. . At present, my country's PET bottle production enterprises have large backbone enterprises with the most advanced PET bottle automatic production lines manufactured by well-known enterprises in the world, and at the same time, there are also a large number of simple and practical products with different degrees of automation designed and manufactured in my country. The small and medium-sized enterprises of the type two-way PET blow molding machine are showing an unprecedented situation of blooming flowers and thriving. At the same time as the rapid development of PET bottles, the production of bottle-grade PET resins in my country has also developed rapidly. The mainstream products of PET bottles in China were initially limited to packaging containers for beverages such as cola, mineral water, and distilled water. They were widely welcomed by users due to their excellent performance and reasonable price. On the basis of application, in recent years, PET bottles have been expanded in the application of heat-resistant bottled beverages such as black tea, green tea, fruit juice, edible oil, cosmetics, medicine, pesticides and other industries. my country's PET bottle plastic molding equipment has great prospects for development. At the same time, we should see that there is a large gap between PET bottle plastic molding equipment and industrially developed countries. In today's internationalized market, domestic PET bottle injection molding equipment, if there is no technical advantage in performance, the developed equipment can only be used as an exhibit, not as a commercial PET bottle blow molding production process polyethylene terephthalate The production of ester (PET) blow molding bottles can be divided into injection stretch blow molding and extrusion stretch blow molding according to the preform of the parison. Among these two molding methods, the injection-stretch-blowing process is easy to control, the production efficiency is high, and the waste and defective products are few, which are more common. PET blow-molded bottles can be divided into two categories, one is a pressure bottle, such as a bottle filled with carbonated beverages; the other is a non-pressure bottle, such as a bottle filled with water, tea, oil, etc. The tea beverage bottle is a modified PET bottle mixed with polyethylene naphthalate or a composite bottle of PET and thermoplastic polyarylate. It is classified as a hot bottle and can be heat resistant above 80 °C; a water bottle is a cold bottle. No requirement for heat resistance. The hot bottle is similar to the cold bottle in the molding process. The author mainly discusses the molding process of pressurized beverage bottles in cold bottles. 1 Equipment With the continuous advancement of science and technology and the scale of production, the automation of PET blow molding machines is getting higher and higher, and the production efficiency is also getting higher and higher. The production capacity of the equipment has been continuously improved, from the previous production of several thousand bottles per hour to the current production of tens of thousands of bottles per hour.
