The English word for plastic is plastic.
1. Origin and Classification of Plastic
(1) Plastic is a malleable polymer material made from synthetic resins through processing.
(2) It originated at the beginning of the 20th century and was first used mainly as a substitute for natural materials such as ivory and wood.
(3) Plastics can be divided into two categories, synthetic plastics and natural plastics, according to their source, and synthetic plastics can be divided into thermoplastics and thermosetting plastics.
2. Characteristics and Advantages of Plastics
(1) Plastics are lightweight, corrosion-resistant, insulating, transparent, and processable, making them widely used in various fields.
(2) Plastic products are inexpensive, and production costs are relatively low.
(3) Plastic materials can be formulated to adjust their properties to meet different needs.
(4) Plastic products are easy to process into a variety of shapes and sizes and are suitable for a variety of processing techniques.
3. Application of plastics
(1) Packaging industry: plastic bags, plastic bottles, plastic containers, etc. are widely used in food, daily necessities, medicine and other packaging areas.
(2) construction industry: plastic pipes, plastic partitions, etc. play an important role in construction projects.
(3) Automobile industry: plastics play an important role in the manufacture of automobile parts, such as plastic body, interior accessories.
(4) Electronic and electrical appliances: plastics are widely used in the shells of electronic products, connecting wires, insulating materials and so on.
(5) medical field: plastics have important applications in medical equipment, medical devices, pharmaceutical packaging, etc..
4. Environmental Problems and Sustainable Development of Plastics
(1) Plastics have negative impacts on the environment during production, use and disposal, such as marine pollution and soil pollution.
(2) In response to the problem of plastic waste disposal, the international community is promoting sustainable development programs for plastics, such as advocating plastic recovery and recycling.
(3) Some new types of biodegradable plastics are under research and development, with a view to playing an active role in reducing plastic pollution.
5. Future Development Trends of Plastics
(1) With the pursuit of sustainable development, the plastics industry is developing in the direction of biodegradable plastics and recycling.
(2) The research and application of green plastics technology will become an important trend in the future development of the plastics industry.
(3) New synthetic plastic materials and advanced manufacturing technologies will continue to emerge to meet higher performance and environmental requirements.
Summary:
Plastic is an important synthetic polymer material with a wide range of applications and advantages. However, the environmental problems caused by plastic waste have also aroused concern, and the development of sustainable development programs and green technology will drive the plastics industry in the direction of more environmentally friendly and recyclable.
