The benefit and harm of plastic
Plastics are synthetic macromolecule compounds, which can also be called macromolecule or macromolecule. They are also commonly known as plastics or resins. They can change their shape freely. It is a kind of material synthesized by synthesis or condensation of monomer raw materials. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. Its main component is synthetic resin.
Plastics have many excellent properties: 1. Light weight and high specific strength. 2. Good resistance to chemicals. 3. Excellent electrical insulation performance. 4. Excellent silencing and shock absorption. 5. Some plastics have good light transmittance. 6. Some resins and plastics have valuable special properties, etc. In addition, in an economic point of view, plastics also have the advantages of simple production process and form, low capital investment and production cost, and saving a large number of metals and other materials. Therefore, the application of plastics is more and more extensive.
It's a pleasure that plastics have so many advantages, which are cheap and convenient, and can be produced in large quantities for the benefit of mankind.
First of all, plastic food packaging is harmful to human health. We use special plastic food packaging bags in food packaging, so other plastic packaging can’t be used for packaging. For example, polyvinyl chloride plastics are toxic. Although polyvinyl chloride resin is non-toxic, it is toxic to add plasticizer and stabilizer in the process of making plastics.
In addition, plastics have a greater impact on the environment. 30% of global plastic production is disposable consumer goods in packaging, household and agricultural fields. These products are generally used for 1 to 3 months or half a year, and the longest time is only about one year. However, most of these disposable plastic products are polyolefin, which are inert materials. They are insensitive to microorganisms and are not easily biodegradable in natural environment. Therefore, the waste plastic packaging scattered along the roads of cities and tourist areas brings bad stimulation to people's vision, affects the overall aesthetic feeling of cities and scenic spots, destroys the city's appearance and landscape, and thus causes "visual pollution". At the same time, after waste plastic packaging entered the environment, it is difficult to degrade, resulting in long-term, deep-seated ecological environment problems. First of all, waste plastic packaging mixed in the soil, affecting crops’ absorption of nutrients and water, which contributed to crop yield reduction; secondly, waste plastic packaging discarded in land or water, swallowed as food by animals, leading to animal death.
At the same time, plastic manufacturing has also brought difficulties to the supply of resources. Over the past few decades, the resource base for large-scale production of plastic products in the plastic industry has been oil. It is reported that about 150 million petroleum and natural gas resources are used in chemical synthesis of "polymer" every year in the world. Oil resources are limited. In the long run, human consumption demand for oil is continuous and endless. One day, oil resources will be exhausted. In recent years, as several major oil-producing countries in the world are facing internal and external problems: war, political turmoil, oil production decline, the energy consumption of China and India, two populous countries, has soared demand for oil, resulting in a sharp rise in oil prices. This growth has brought about a great contradiction and impact on the supply and demand of the plastic industry.
Therefore, in order to solve the problems of environmental pollution and resource shortage, we put forward plastic recycling.
What is plastic recycling? Plastic recycling is the process of recycling waste plastics and reusing waste plastics. There are two main ways to recycle waste plastics. One is to regenerate plastics into raw materials of the same species or to decompose them into monomers, the other is to make them into other materials or energy that can be used synthetically. Among them, the direct regeneration method is to clean, crush and plasticize the old plastics for directly process or pelleting.
