With the continuous rapid development of economy and society in China, the demand for iron ore is also growing day by day. Facing the sharp upward pressure on international iron ore prices, plastics are gradually becoming the best alternative to steel by virtue of its unique performance advantages.

"Taking plastics as a substitute for steel" is an inevitable trend of environmental protection and sustainable development in the new century. Plasticizing enterprises should assume greater responsibility in promoting the application of new materials and in response to the utilization of environmental protection and renewable resources.

"Plastic Steel" cracked China iron ore demand dilemma
With the rapid economic and social development in China, China's steel industry has also made rapid development. At present, China has become the world's largest iron ore importer. According to the statistics of the General Administration of Customs, China imported a total of 619 million tons of imported iron ore in 2010, while its import volume in 2000 was only 69 million tons, an increase of nearly 10 times in 10 years. Faced with such a huge "appetite" for China's iron ore, international mining giants such as BHP Billiton and Vale began to arbitrarily use their monopoly position to promote the ore-based pricing model and exclude China from the global iron ore price Outside the core negotiations. How to reverse the domination of the people has become an important issue that troubles the Chinese steel industry and even the government.

Plastic to replace steel, plastic to non-ferrous metal will be the future development of China's major market trends, deputy director of Ningbo Science and Technology Bureau, CAS Ningbo Institute of Materials Technology and Engineering He Xiaonan, deputy director, said plastic with light weight, corrosion resistance, impact resistance Good, good insulation, good thermal conductivity, design space, low manufacturing costs and other unique advantages, since its inception, its prospects have been generally favored. With the increasing use of plastic raw materials, the current general plastics will be developed to higher strength, better impact engineering plastics, composites or plastic alloys, at the same time, this development will also greatly promote the material in the recyclable Use of research and development.

Applications continue to expand, "Plastic Steel" trend
With the rapid development of plastic industry in recent years, plastic has been widely used in agriculture, building materials, packaging, machinery, automotive, electronics, petrochemicals and human daily life and other fields. Plastic products to replace metal products is the trend of the times, the future of China's plastics industry trends in three directions, first of all, construction, packaging materials; followed by appliances and automotive industries; the third is engineering plastics and modified plastics.

In recent years, "Plastic Steel" performance in the automotive sector is very eye-catching. According to automotive industry experts, plastic applications in the car has been very broad, according to the function of the application is divided into three categories, namely, interior parts, exterior parts and functional parts. At present, foreign automobile interior parts have been basically plasticized. The new trend of plasticization of automobiles will be gradually extended to ordinary decorative parts including seats, lights, handles, ceilings, dashboards and sun visors to include fuel tanks, fenders, fans Leaves, etc., the functional structure. It is understood that developed countries such as Europe and the United States and even the amount of plastic car, as a measure of the level of automotive design and manufacturing an important symbol. At present, 20% of the weight of foreign vehicles is modified plastics, while the domestic ratio is 11%. Under the trend of light weight of automobiles, the market of modified plastics is promising.

Modern architecture requires building materials to be environmentally friendly, lightweight, high-strength, multi-purpose and prefabricated. Plastics are meeting this need. Some experts said the pipe as an example, the application of plastic pipe with energy saving, water, land, materials, recyclable and so on, showing that plastic pipe alternative metal pipe has great advantages. Data show that each outer diameter of 150 mm of HDPE (high density polyethylene) pipe weighs only 5 kg per meter, while ductile iron is 24 kg, copper is 28 kg.
