    Since the early 1950s, China's carbon black industry from scratch, has developed a number of production technology, and independent research and development of carbon black special equipment, reached the international advanced level -
    in 1949, when the founding of New China, China's carbon black industry is almost blank. After 70 years of industry-wide efforts, China's carbon black industry from nothing, from small to large, the current production capacity and output are ranked first in the world, and gradually to the world carbon black power.
    china's carbon black industry began in 1950 in Longchang, Sichuan Province, the establishment of the slot method carbon black test

    . By 1957, China had set up 11 carbon black factories, production tank method, mixed gas, rollers and sprays and other varieties of carbon black, carbon black annual output increased to 8700 tons. In the 1960s, China also developed the successful acetylene carbon black, general furnace carbon black (N660) and medium ultra-wear-resistant carbon black (N220), the annual output of carbon black increased to 50,000 tons. In particular, in the 1970s, the new process carbon black development success, exhaust power generation plant put into operation, so that the national annual carbon black production rose to 190,000 tons.
    1980, China's carbon-black industry has seized the great opportunity of reform and opening-up and achieved rapid development. In 1999, carbon black industrial research and design institute was transformed into a science and technology-based enterprise, who wholisted into the China Union Rubber Group and changed its name to china Oak Group carbon black industrial research and design institute. In July of the same year, jiangxi Jingdezhen coking plant carbon black plant 8000 tons / year production line was transformed into 15,000 tons / year production line; Since then, Suzhou Baohua Carbon Black Co., Ltd. 40,000 tons / year carbon black production line completed and put into operation, China's carbon black enterprises independent innovation to speed up.
    In 2000, China Synthetic Rubber Co., Ltd. acquired the original Maanshan Carbon Black Factory, the establishment of Zhong Oak (MaAnshan) Chemical Industry Co., Ltd., and the next year the acquisition of the former Anshan Chemical Co., Ltd. established Zhong Oak (Anshan) Chemical Industry Co., Ltd., Shanxi Polyyuan Carbon Black Co., Ltd., Shanxi Yongdong Chemical Co., Ltd., Jiangxi Black Cat Carbon Black Co., Ltd. have also been established.
    to 2003, China's carbon black production has reached 1.02 million tons, almost doubled from 1998, the first time over the United States to become the world's largest carbon black production and consumption, and the leading edge continues to expand. From 2003 to 2013, China's carbon black industry developed rapidly for 10 years, the domestic carbon black production capacity at an average annual increase of 400,000 tons. By 2018, the country's total carbon black production capacity has reached 7.52 million tons, the output of 5.7 million tons.
    , the development of carbon black production technology in China has experienced about 5 stages of development. In the early 1950s, China's carbon black industry started from zero, has successfully developed the groove carbon black, roller carbon black, mixed gas carbon black and gas furnace carbon black production technology, and began industrial production. In the late 1950s and 1970s, while producing carbon black varieties with natural gas as the main raw material, the production technology of carbon black of oil furnace method was developed and gradually improved, while the production technology of acetylene carbon black was developed. From the late 1970s to the 1980s, China successfully developed a new process of carbon black production technology and rapidly popularized, so that China's carbon black varieties increased, quality improvement, raw material oil consumption decreased, to achieve the first technological leap. At the same time, enterprises began to use the residual heat and exhaust gas of the carbon black production process. From the late 1980s to the end of the 20th century, China introduced tons of carbon black production equipment from abroad, and on this basis carried out digestion and absorption and upgrading innovation, to achieve the domestic carbon black industry's second technological leap.
    After nearly 70 years of development, especially 40 years of reform and opening up, China's carbon black industry has achieved extraordinary results, China's independent research and development of a single reactor capacity has reached 30,000 to 40,000 tons / year; During this period, carbon black production equipment such as reactor, high temperature air preheater, bag filter, wet granulator, dryer, micron shredder, automatic packaging machine, on-line residual heat boiler, exhaust boiler and other special equipment, as well as carbon black reactor with high temperature refractant materials, high-efficiency glass fiber filter bag development and production, but also further development, reduce the construction investment of carbon black device, shorten the construction cycle. The quality of some special equipment has reached the advanced level abroad, which greatly meets the needs of the development of carbon black production in China.
    the 21st century, domestic carbon black enterprises to large-scale installation, energy conservation and environmental protection as the main goal, but also developed a number of new technologies and new equipment, so that China's carbon black industrial development to a new level.
    , however, with the rapid development of the automobile and tire industry in recent years, the upstream carbon black industry blindly developed projects to expand production capacity, resulting in structural excess problems highlighted, the industry capacity utilization rate has been at a low level for a long time. Wei Ming, chairman of the carbon black branch of the China Rubber Industry Association and general manager of Jiangxi Black Cat Carbon Black Co., Ltd., pointed out that the carbon black industry is saying goodbye to the era of high growth and entering the new normal of "micro-growth". At present, domestic enterprises high-end product research and development capacity is not strong, unreasonable industrial structure, become an obstacle to the healthy development of the carbon black industry, the future should pay attention to new product design and development, international brand building, high-grade professional and technical personnel cultivation, and in product quality, enterprise management, sales services, product variety upgrading and other aspects to achieve leapfrog.
