In the production of wire and cable, because the cost of raw materials accounts for more than 80% of the production cost, and copper, aluminum, steel core, rubber, plastic and sheath materials are the mainstay of raw material costs, which requires wire and cable enterprises. Work hard on designing distinctive products, saving raw materials, and developing new environmentally friendly materials. Therefore, the following measures must be considered in the future to create a circular economy in the wire and cable industry:
First, eliminate the cold rolling mill and the black copper rod. The production process of rolling the 芰8 black copper rod by cold rolling mill is backward, and its black copper rod has high oxide content, low electrical conductivity, poor performance, small tensile force ratio, consumables, energy consumption and serious pollution. Eliminated.
Secondly, actively promote the optimization technology of aluminum rare earth.
The production of electrical aluminum rods by continuous casting and rolling process has been quite popular in China, and the performance is also good, but the equipment still stays at the development level in the early 1970s, and there is not much innovation in technology. It is necessary to actively promote the unique aluminum rare earth optimization treatment technology in China. The aluminum-zirconium alloy is added to some of the key special equipments and technologies introduced, and the molten aluminum coal-fired furnace is transformed into a molten aluminum fuel or natural gas furnace, all of which eliminates the emission of coal-fired soot and flue gas from the molten aluminum coal-fired furnace, and sets the flue gas. The filter device purifies the flue gas, improves the discharge quality, improves the yield, reduces the cost, and increases the working temperature of the wire from 70 ° C to 150 ° C, and the current carrying capacity is increased by 1.6 times.
Third, actively introduce technology and independently develop and develop special equipment for wire and cable with excellent performance.
At present, the key production equipment of wire and cable leading products is still very different from foreign advanced equipment. The main technical gap is that the productivity is low, the degree of automation is not high, the energy consumption is large, the reliability is poor, and the development of the industry cannot be satisfied. Need, digestion and absorption is seriously delayed. The technical level, performance and reliability of wire and cable special equipment have incalculable benefits for improving wire and cable product quality, production efficiency and material utilization. It is necessary to actively introduce technology and independently develop and develop high-performance wire and cable equipment with high performance and to provide circular economy services for the wire and cable industry. Finally, we will actively develop environmentally-friendly wire and cable products and strengthen the recycling of waste wire and cable products.
At present, a large number of polymer materials such as rubber, polyvinyl chloride and polyethylene are used in the production of wire and cable products. A large amount of toxic and harmful gases are generated during the production of wire and cable products. Therefore, we must actively develop environmentally-friendly wire and cable raw materials and produce environmentally friendly wire and cable. After developing environmentally-friendly wire and cable products, Japan’s Fujikura and other cable companies have actively promoted the government’s environmentally-friendly wire and cable product standards in order to monopolize the market. In recent years, the sales share of environmentally-friendly wire and cable products has expanded dramatically, and ordinary wire and cable and flame-retardant wire and cable cannot compete with it at all.
The residual material generated in the production process of wire and cable can be directly recycled and reused. It is recommended to set up a professional "polyvinyl chloride" waste recycling treatment plant, fixed-point processing, and use it for other purposes to avoid secondary pollution.
