1. Recycling technology for metal materials
According to relevant practical research, we can see that 80% of the automobile is made of metal materials, so if these materials can be effectively recycled, it will directly increase the overall recycling value. For most of the car companies, the ideal recycling method is directly on the end-of-life vehicle metal parts for secondary use, and at the same time, can also be directly applied to other vehicles after repair. For those parts that cannot be used in end-of-life vehicles, they are effectively recycled in the form of materials.
The recovery of steel is mainly through the method of steelmaking. As we all know, scrap iron and steel is the main material for steelmaking, and its overall dosage is as high as about 80% of the raw materials of steel. At the same time, scrap iron and steel in the oxygen converter is not only a metal material, we can also see it as a coolant.
Scrap aluminum materials in end-of-life vehicles to achieve recycling, mainly through direct melting into recycled aluminum alloy ingots, processed into aluminum materials used in ingot billets as well as direct melting and casting of the three main forms.
Magnesium recycling can be used mainly in two main forms of distillation and dissolution method. First, for the distillation method, is essentially pure magnesium recovery, but the specific operation is extremely complex, need to consume a lot of energy, so in the automotive end-of-life zero device recovery is not often used. The dissolution method is the main magnesium alloy recycling method, which adopts the process of melting, de-oxidizing, removing iron, increasing chemical composition, de-gassing, and ingot casting to realize efficient recycling.
2. Plastic materials recycling technology
Direct melt regeneration
Specifically, the technology is directly the waste plastic through the sorting, cleaning, crushing, molding and so on the process of direct molding methods and methods, generally speaking, this technology is only used in the recovery of poor quality plastics.
Modified regeneration
This technology mainly refers to the obtained waste plastics through physical or chemical ways to change its skills, especially mechanical properties will have obvious improvement. Generally speaking, we will use physical modification and chemical modification two main methods for plastic recycling.
3. Rubber material recycling technology
Old tires directly retreaded
Directly old tires for partial repair, secondary processing, affixed to the tread rubber and then use certain ways and means to make it vulcanized, so as to give play to its value. This way and method to a certain extent requires a better quality of the tire source, at the same time the level of relevant technical personnel to reach a certain standard, which is also an important part of the rubber industry recycling in China.
Vigorous production of vulcanized rubber
The so-called vulcanized rubber powder, mainly refers to the vulcanized rubber directly crushed and then produced powdery substances. It is worth noting that the material produced by this process we can understand it as fine rubber powder, and after its vulcanization of the overall performance is more prominent compared to recycled rubber, can be flexibly used in the construction industry, highways, airports, decoration, rubber products, and other decorative materials, the integration of environmentally friendly resources, regeneration and other diversified recycling, but at present our country for the use of rubber powder is not comprehensive.
Effective production of recycled rubber
The so-called recycled rubber, mainly refers to the vulcanized rubber through crushing, heating and other physicochemical operations, so that its characteristics from the initial elasticity to plasticity and viscosity, but also has a certain re-curing ability. This technical method is currently the most widely used recycling technology, which has been flexibly used in various countries and regions.
4. Recycling technology of glass materials
The recycling of glass is divided into two main modules: direct utilization and transformational utilization. Firstly, the so-called direct utilization is to dismantle the quality-inspected qualified glass in end-of-life vehicles directly for the design of other vehicle parts; secondly, the so-called transformational utilization is to process all the glass directly after recycling and transform it into raw materials.
In a certain sense, most of the glass in the end-of-life car is usually transformed to utilize the way directly back to the melting furnace, and then through certain ways and means to make it into glassware. At the same time, the broken glass and carbon powder can be directly mixed up, and then add certain raw materials, through the firing can replace the mineral wool foam glass material. In addition, glass and plastic can be used directly in the production of asphalt and concrete as an additive to concrete, which can make the building more robust.
For laminated glass, its own structure has a certain degree of complexity and specificity, so in its recycling before the first glass and glass between the polymer should be effectively separated, through the heating of the way to convert polymer to realize the separation of the glass and its separation, and then recycled separately. However, it is worth noting that the overall recycling value of laminated glass is low, so we usually end-of-life vehicles in the laminated glass directly to landfills.
