Ethylene amines refers to the acyclic ethylenediamine polymer products, as an important fine chemical intermediates, ethylene amines in organic synthesis, medicine, dye, pesticide, chemical fertilizer, rubber plastic additives, organic solvents and epoxy resin curing agent, and other fields has been widely used. which become to be one of the fine petrochemical intermediates for the development of China. Ethylenediamine (EDA) is a very important intermediate, mainly used to produce EDTA(chelating agent) and TAEDA(bleach activator), can also be used to produce Organic Dye, Dye-fixing Agent, coating, pesticide, etc. Piperazine can be used to produce anhydrous piperazine, n-methyl piperazine, n-ethyl piperazine, pharmaceutical intermediates, fluperacid, halogen free flame retardant, triethylene diamine. Piperazine has been exported to India and Japan.

Since the State approved the establishment of the first national key laboratory in the field of remanufacturing in 2001, China's automobile remanufacturing has gone through a 12-year history of development. Compared with the mature remanufacturing markets in Europe and the United States, although China's automobile remanufacturing has made great progress in technology, it is in a situation of “internal cooling and external heatâ€.
What is car remanufacturing?
Automobile remanufacturing, also known as remanufacturing of auto parts, broadly speaking, takes product life cycle theory as a guide to achieve the goal of improving the performance of used products, and regards high quality, high efficiency, energy conservation, material saving, and environmental protection as guidelines, and Parts are repaired and rebuilt to recycle used parts and components.
Under normal circumstances, automotive remanufactured products mainly include internal combustion engines, tires, transmissions, clutches, steering gear, starters, carburetors, brake shoes, water pumps, air conditioning compressors, wiper motors, oil pumps, and brake actuators. , power control pumps and buffers, etc.
China's automobile remanufacturing is still in the pilot and promotion stage. The automobile remanufacturing products mainly focus on engines, starters and generators, gearboxes, tires, and steering systems. Among them, the remanufacturing of automobile engines, transmissions, generators and starters occupies a large proportion.
Car remanufacturing output value has reached 8 billion
According to data released by the China Association of Automobile Manufacturers on China's auto parts manufacturing remanufacturing data for 2010, China produced about 110,000 remanufactured engines in 2010, produced about 60,000 more transmissions, and manufactured about one million more generators and starters. . In June 2012, the State Council issued the “12th Five-Year Plan for Energy-saving and Environmental Protection Industry Development†and proposed that by 2015, 8 million sets of remanufactured engines, gearboxes, starters, and generators will be remanufactured.
Xie Jianjun, secretary-general of the Auto Parts Remanufacturing Branch, said: In 2012, the output value of China's automobile remanufacturing industry has reached 8 billion yuan. In 2005, the output value was less than 0.5 billion yuan. In 2010, the output value was less than 2.5 billion yuan, and the overall market scale expanded rapidly.
Three major problems restrict the development of the industry
The “2013-2018 China Automotive Remanufacturing Industry In-Depth Survey and Investment Strategic Planning Analysis Report†research shows that although China’s auto remanufacturing industry has great development potential, it is still at the market’s primary level in view of the development status in recent years. stage. There are still factors that restrict the development of the industry in the areas of national laws and market applications.
