In today's society, the development and application of environmentally friendly materials have attracted more and more attention. As a new type of material, EPP(Expanded Polypropylene, expanded polypropylene) stands out in many fields for its environmental protection characteristics.
Environmental advantages of 1. raw materials
The main raw material for EPP is polypropylene, a widely used and relatively readily available thermoplastic resin. Polypropylene itself has good recyclability and renewability. It is derived from petrochemical products, but compared with some traditional plastics that are difficult to degrade, polypropylene degrades relatively quickly in the natural environment. Moreover, with the continuous development of biodegradable polypropylene technology, the raw materials of EPP will be more environmentally friendly in the future.
Environmental performance of 2. production process
1. Low energy consumption process
The production of EPP adopts the physical foaming process, which greatly reduces the pollution to the environment compared with the traditional chemical foaming process. In the physical foaming process, gas (such as carbon dioxide or nitrogen) is injected into polypropylene particles at high temperature and high pressure to expand them to form a foam structure. This process does not require the use of large amounts of chemical blowing agents, thereby reducing chemical emissions and potential harm to the environment.
At the same time, the energy consumption of the physical foaming process is relatively low. In the production process, the required heating temperature and pressure are relatively low, which reduces the demand for energy and meets the environmental protection requirements of energy saving and emission reduction.
2. No pollution discharge
EPP production process almost does not produce waste water, waste gas and waste residue and other pollutants. Through the advanced waste gas treatment system, the factory can effectively treat the very small amount of volatile organic compounds (VOCs) produced in the production process, so that its emissions meet environmental protection standards. For the scrap and unqualified products produced in the production process, EPP can be reprocessed through the recycling system to realize the recycling of resources and further reduce the impact on the environment.
Environmental value in the use of 3.
1. Lightweight to reduce energy consumption
In the field of product application, EPP has made an important contribution to environmental protection with its lightweight characteristics. For example, in the automotive industry, the use of EPP materials for automotive parts can significantly reduce the overall weight of the car. According to research, for every 100kg of car weight reduction, fuel consumption per 100 kilometers can be reduced by about 0.3-0.6 liters. This not only reduces the energy consumption during the operation of the car, but also reduces the environmental pollution caused by exhaust emissions.
In the field of logistics and transportation, the use of EPP packaging materials can reduce the weight of goods, improve transportation efficiency, and reduce energy consumption and carbon emissions during transportation.
2, non-toxic and tasteless to protect human health
EPP does not release harmful substances during use, and is non-toxic and tasteless. This is of great significance for products that are in close contact with the human body, such as children's toys and household goods. It does not cause any potential harm to human health and meets the dual requirements of environmental protection and health. At the same time, the use of EPP materials in the indoor environment will not release harmful gases such as formaldehyde, which will help improve indoor air quality.
Environmental Protection Treatment of 4. after Abandonment
1, can be recycled
EPP has good recyclability. Waste EPP products can be collected and disposed of through professional recycling channels. The recycled EPP material can be crushed, cleaned, melted and other processes to be remade into new EPP products or other plastic products. This recycling method greatly reduces the demand for raw materials, reduces the waste of resources and the amount of landfill.
2, can be naturally degraded
Although the degradation rate of EPP is relatively slow, but in the natural environment, after a certain period of time and conditions, EPP can still be gradually degraded. For example, in soil, microorganisms can break down the polypropylene component of EPP, turning it into harmless substances. In the marine environment, EPP will not cause long-term harm to marine life like some traditional plastics.
To sum up, EPP shows remarkable environmental protection characteristics from the selection of raw materials to the production, use and disposal after disposal. It not only meets the needs of modern society for environmentally friendly materials, but also provides strong support for the sustainable development of various industries. With the continuous advancement of technology and the continuous improvement of environmental awareness, the environmental performance of EPP will be further optimized and improved, and will play a more important role in the future environmental protection field.
