Key issues for the development of new wire and cable materials

In the production of wire and cable, since the raw material cost accounts for more than 80% of the production cost, materials such as copper, aluminum, steel core, rubber, plastics, and sheathing are the main raw material costs, which requires the wire and cable enterprises to Designing distinctive products, saving raw materials, and developing new environmentally-friendly materials, etc. Therefore, the following measures must be considered in the future to create a circular economy in the wire and cable industry:

First, we eliminated cold rolling mills and black copper rods. The production process of rolling 芰8 black copper rods by using a cold rolling mill is backward, and its black copper rods have high oxide content, low electrical conductivity, poor performance, low pull-to-weight ratio, serious consumables, energy consumption, and pollution. Eliminated.

Second, actively promote the optimization of aluminum rare earth processing technology. The production of electrical aluminum rods by the continuous casting and rolling process has become quite popular in China, and the performance is also good. However, the equipment still remains at the level of development in the early 1970s, and there is not much innovation in technology. To actively promote China's unique aluminum rare earth optimization processing technology. The aluminum-zirconium alloy is added to some of the key special equipment and technologies introduced, and the aluminum-fired coal-fired furnace is transformed into a molten aluminum fuel or natural gas furnace. All the coal-fired fumes and fumes emitted from the coal-fired fusion furnace are eliminated, and the flue gas is set. The filter device purifies the flue gas, improves the discharge quality, increases the yield, and reduces the cost. At the same time, the working temperature of the wire is increased from 70° C. to 150° C., and the current-carrying capacity is increased by 1.6 times.

Third, actively introduce technology, independent innovation and development of excellent performance of wire and cable equipment. At present, the key production equipment for wire and cable leading products is compared with foreign advanced equipment. The gap in technology level is still very large, mainly reflected in low productivity, low degree of automation, high energy consumption, poor reliability, and can not meet the development of the industry. Needs, digestion and absorption are seriously delayed. The technical level, performance and reliability of special equipment for wire and cable have incalculable benefits for improving wire and cable product quality, production efficiency and material utilization. To actively introduce technology, independent innovation and development of excellent performance, high-level special equipment for wire and cable, in order to create a circular economy services wire and cable industry. Finally, actively develop environmentally friendly wire and cable products and strengthen recycling of waste wire and cable products. At present, the production of wire and cable products uses a large number of rubber, polyvinyl chloride, polyethylene and other polymer chemical materials. Produce a large number of toxic and harmful gases in the production of wire and cable products. Therefore, we must actively develop environmentally friendly wire and cable raw materials, production of environmentally friendly wire and cable products. After Japan Fujikura and other cable companies developed environmentally friendly wire and cable products, in order to monopolize the market, they actively promoted the government's enactment of environmentally friendly wire and cable product standards. In recent years, the sales share of environmentally friendly wire and cable products has expanded dramatically, and ordinary wire and cable and flame-retardant wires and cables have been unable to compete with them. In the production process of wire and cable corners surplus material can be recycled directly. It is recommended to set up a professional "polyvinyl chloride" waste recycling plant that will be processed at specified points and used for other purposes to avoid secondary pollution.
