How to choose environmentally friendly raw materials and manufacturing processes to reduce the negative impact of prefabricated rubber track membrane on the environment?

At a time when sports facilities construction is booming, prefabricated rubber track membrane is widely used, but its environmental issues have attracted much attention. Choosing environmentally friendly raw materials and manufacturing processes has become the key to the industry's green transformation.In terms of raw material selection, natural rubber is a good choice. Compared with synthetic rubber, it comes from rubber trees, is renewable, has low energy consumption in the extraction process, and reduces carbon emissions. On the premise of ensuring the performance of the runway membrane, increasing the proportion of natural rubber can reduce dependence on petroleum-based raw materials and avoid pollution caused by mining and refining. At the same time, environmentally friendly fillers such as calcium carbonate whiskers are used to replace traditional carbon black. Calcium carbonate whiskers are non-toxic and harmless, and have a wide range of sources. They not only reduce costs, but also improve the mechanical properties of the product, and reduce the release of harmful substances during the use and disposal stages of the runway. In addition, it is crucial to select biodegradable plasticizers, which can ensure the flexibility of the runway and can decompose naturally over time after use to avoid soil and water pollution.Manufacturing process optimization is also indispensable. The use of low-temperature continuous vulcanization technology is a major breakthrough. Traditional high-temperature vulcanization consumes a lot of energy and is prone to produce volatile organic compounds (VOCs). Low-temperature vulcanization precisely controls the reaction in a lower temperature range, greatly reducing energy consumption, inhibiting the generation of harmful gases, and accurately controlling the degree of rubber cross-linking, thereby improving the quality and stability of the runway membrane. The introduction of water-based adhesives to replace solvent-based products uses water as a dispersion medium. There is almost no organic solvent volatilization during the construction and drying process, eliminating the pungent smell in the workshop, reducing the risk of explosion, making the working environment safer for workers, and ensuring the surrounding air quality.The combination of a precise batching system and an automated production line can achieve precise delivery of raw materials, reduce waste and defective rates. Automated equipment monitors process parameters in real time to ensure standardized operation of each link and avoid excessive material loss or environmental pollution due to human errors. A mechanism for recycling and reusing production waste also needs to be established. Leftovers and unqualified products are crushed and recycled, and then reintegrated into the raw material system. The closed-loop management of material flow can reduce the "harm" of prefabricated rubber track membrane to the environment from the source and process in all aspects, paving the way for green sports.
