The history of the development of silicones in my country is due to the contribution of downstream private enterprises!silicone license plate frame reddit manufacture

　　Since the beginning of the 21st century, the private enterprises that use methylchlorosilane as the main silica gel products have made great progress in the downstream enterprises of organic silica gel products in my country. Due to the serious shortage of methyl chlorosilane production capacity of state-owned enterprises, the growth of methyl chlorosilane production is still far from meeting the needs of downstream enterprises. The price of the primary form of polysiloxane on the Chinese market once approached 40,000 yuan per ton.

　　Some far-sighted private entrepreneurs see that silicone is a high-tech industry encouraged by the state; the main raw materials, silicon metal, methanol and hydrochloric acid, can all be based in China. They also know that all kinds of silicone products are important materials to support the national economy, and China must not have its own silicone industry. As far as the author knows, the general manager of Foshan Hualian Xu Feng and others assisted Mr. Luo Liguo in planning the establishment of a private silicone monomer factory.

　　When some private enterprises started, the production capacity of methylchlorosilane was generally only 60,000 tons/year. Although the scale is not large, it starts from the procurement or preparation of raw materials such as chemical-grade silicon blocks, methanol, and catalysts with strict quality requirements, and goes through monomer synthesis, rectification, hydrolysis, and cracking to the synthesis of polysiloxane. Don't invest a lot of energy and money. Therefore, the establishment of private organosilicon enterprises is by no means achieved overnight.

　　Zhejiang Hesheng (originally known as Jimei), which started relatively early, has been developing very well under the operation of Chairman Luo Liguo since it was successfully put into operation in early 2007 and has always been profitable. The plant has developed to Xinjiang, which is rich in coal resources; it has also developed chemical-grade silicon production in the northeast by using nearby resources such as cheap electricity and charcoal. Many private enterprises, such as Zhejiang Hengyecheng and Shanxi Sanjia, are developing in Inner Mongolia, which is rich in coal resources, in order to reduce costs. It seems that the focus of most private enterprises is to vigorously reduce the production cost of monomers in order to gain a foothold.

　　The common feature of China's private entrepreneurs is their unremitting self-improvement and unstoppable pursuit of technological progress. With the help of retired senior engineers, master workers and university professors who had previously engaged in silicone research or production, they have continuously improved their craftsmanship, improved their level and expanded their scale. With the joint efforts of all the different types of silica gel product factories, the actual annual output of the fluidized bed for synthesizing methylchlorosilane can reach 80,000 tons, 100,000 tons or even more. At present, the largest single fluidized bed among Chinese-funded enterprises in China, designed by Prof. Li Jianlong of Qingdao University of Chemical Technology and capable of producing 150,000 tons of methylchlorosilane monomer per year, has also been successfully operated in the private Shandong Jinling Chemical Company.

　　At the beginning of the new century, due to the joining of a large number of private enterprises, China's silicone industry has undergone gratifying changes. From 2005 to 2007 and 2008, a number of monomer plants were built and put into operation.

　　The joining of private enterprises made the output of methyl monomer produced by Chinese-funded enterprises reach about 570,000 tons in 2009, increased to 850,000 tons in 2010, approached 1 million tons in 2011, exceeded 1 million tons in 2012, and stopped in 2013. Less than 1.3 million tons, in 2014 it was estimated to be around 1.5 million tons. It can be seen from Table 2 that there are more than ten Chinese-funded organosilicon enterprises with methylchlorosilane products. Among them, the total amount of methylchlorosilane produced by private enterprises has accounted for more than half of the total output of Chinese-funded enterprises in the country. Due to the rise of private monomer enterprises, the domestic shortage of methyl chlorosilane was quickly reversed.

　　The increase in the production of methylchlorosilane in my country has not only greatly eased the tight supply of intermediates, but also made the self-sufficiency rate of methylchlorosilane in China over 70%. Moreover, a large number of private silicone downstream product enterprises have used domestically produced raw materials, giving full play to their potential in meeting the needs of national defense and the national economy. The joining of upstream and downstream private enterprises has added strength to the young Chinese organosilicon industry; it has played a pivotal role in boosting the development of China's organosilicon industry. Their efforts have greatly changed the weak position of Chinese-funded silicone companies in the market, and China's private silicone companies have contributed greatly!
