19 13 years, he came to Tanggu for field investigation and found that Tanggu is a unique saline-alkali industrial base. Subsequently, with the support of Fan Yuanlian, then Minister of Education of the Republic of China, and his mentor Liang Qichao, Fan Xudong was founded by, Jing, Hu Ruitai, Li Jiyun, Fang Jilin, and was initiated by Liang Qichao, Fan Jingsheng, Wang Jiaxiang, Liu, Chen Guoxiang, Zuo Shuzhen, Li Mu and Qian Jinsun. 1968. At that time, the nine major shareholders were assisted by many military and political officials such as Li, Cao Kun, Cai E and Feng Yuxiang.
1965438+On April 6th, 2006, Jiuda Refined Salt Plant was completed and put into operation. In September of the same year 1 1, the first batch of refined salt was transported from Tanggu to Tianjin for sale, and then sold to Hunan, Hubei, Anhui, Jiangxi and other places. At this time, Jiuda refined salt began to reach the production capacity of 5 tons per day, with a profit of 500,000-600,000 yuan per year. After the expansion of 19 19 East Plant, the annual output can reach more than 62,000 tons. The completion and commissioning of Jiuda Refined Salt Plant provided raw materials and talents for the establishment of Li Yong Alkali Plant in the future, especially in terms of funds. 1965438+In August, 2004, World War I reduced the import of foreign caustic soda to China, and factories in Tianjin and Shanghai with soda ash as raw materials stopped working. At that time, the world soda industry had a history of 100 years, but at that time, China relied on "oral alkali" which was dissolved into alkaline water and then solidified into blocks. This "oral alkali" is of poor quality and extremely unsanitary. At the end of 19, "foreign caustic soda" began to be dumped in China, and a large amount of gold flowed out because caustic soda could not be manufactured in China.
19 14 years, based on the establishment of Jiuda Refined Salt Factory, Fan Xudong decided to "change salt into alkali" and set up "Li Yong Alkali Company", which was the first in China Alkali Industry. At that time, the British Bunniemen Company, which monopolized Solvay soda production technology, was worried that once Wynn soda production succeeded in squeezing out its market in China, it proposed to "cooperate" with Wynn soda production company to achieve the purpose of annexation, but it was rejected. Li Yong Soda Plant adopted the advanced soda production technology of Solvi in the world at that time, with a design capacity of 40 tons of soda per day. All the machines and equipment that can be manufactured in China are manufactured by Shanghai Dayao Iron Works, and all the machines and equipment that cannot be manufactured are purchased from abroad. From 19 18 to 1924, Li Yong Alkali Industry Company began to recruit talents for the design and infrastructure of alkali plants.
1918165438+10. In October, Director Chen Tifu went to the United States to invite consultant engineer W.D.Mount to take charge of the design, but the actual design work was undertaken by China students. At that time, Hou Zai 19 19, who was studying in the Department of Chemical Engineering of Columbia University, accepted the invitation of Steve Chen and participated in the design of Yongli Soda Plant.
192 1 year, Hou received his doctorate and was hired as an engineer of Wynn soda company.
1923, most of the mechanical equipment in the soda plant was installed and put into single-machine debugging one after another. The raw salt used comes from Luchang Yantian, and limestone and pulverized coal are supplied by Tangshan Beijiadian Stone Mine and Kailuan Coal Mine respectively. On August 1924 and 13, Li Yong Soda Plant started to produce alkali for the first time. But the produced alkali is red and black and can't be sold. In March of the following year, the main equipment drying pot burned out, which led to the shutdown of the whole plant.
On June 29th, 1926, Li Yong Soda Plant was restarted after it was put into production again, and white products with sodium carbonate content exceeding 99% were produced. In order to distinguish "oral soda" produced by indigenous method from "imported soda", Fan Xudong named its product "soda ash" and determined the trademark of "Red Triangle" brand. China's "Red Triangle" brand soda won the highest honor gold medal, 1926, at the World Expo held in Philadelphia in August, realizing the first export of chemical products produced in China. After 1930, the "Red Triangle" soda won the gold medal in the Belgian Chamber of Commerce and Industry. The "Red Triangle" brand soda produced by Li Yong Soda Factory won the international prize twice, which laid the foundation of modern chemical industry in China. After the success of Wynn soda production, the development was difficult in the face of malicious competition from British companies and exploitation by warlords and bureaucrats. In order to monopolize the alkali industry market in China, the British businessman Bunniemen Company took advantage of Britain's privilege in China, and through the British Foreign Secretary and its diplomatic envoys in China, ordered the Salt Industry Holding Corporation to operate the British Ding En after the first alkali production in Wynn Alkali Factory in 1924. Without the approval of the government of China, a tax regulation on industrial salt was published without authorization, which stipulated that the tax should be 20 cents per 100 kg of industrial salt. In this regard, Wynn resolutely protested and exposed it in various ways. After many twists and turns, Dean agreed to temporarily waive for one year under the pressure of public opinion, and agreed to extend it for five years on 1925. On 1930, it was agreed that the industrial salt of Li Yong soda plant would be exempted from tax for 30 years.
Li Yong soda plant started construction for the second time on June 29th, 1926. After producing the first-class products, Buniemen Company took the measures of greatly reducing the price of soda to 40% of the original price, and crushed Li Yong soda plant in the market. In June, an English-language newspaper in Shanghai, Continental Daily 1925, published an article entitled "Look at Britain's methods of destroying domestic products", accusing the British Bunemen Company and calling on the people to support the national industry and Wynn soda factory. At the same time, in order to cope with this unfavorable situation, Wynn counterattacked in the Japanese market in the same way, selling alkali in the Japanese market at a price lower than that of Bouniemen Company, which caused huge losses to Bouniemen. In less than a year, Bunemen was forced to take the initiative to make peace, and declared that he would never arbitrarily reduce the price in the China market in the future. In the early stage of its development, Wynn Alkali Industry Company and Bunniemen Company both ended in victory.
In the early days of its establishment and development, soda plants were used by warlords and officials. Most of the raw fuel needed for production is transported by railway. Tanggu is a military important place, and also an important station and port of Beijing-Fengjing Railway. Due to the frequent military transportation caused by years of civil war, it is often impossible to send trucks to load materials for alkali plants for many days, which affects production. In addition, warlords often levy various transportation taxes. For example, the surtax on raw salt is 20 times higher than that of Ding En. Because transportation is often blocked, the finished soda ash can't be shipped out in time. The extremely unstable social environment led to the chaos of Tianjin's financial market and the increase of bank interest, so Li Yong Soda Factory had to borrow at heavy interest to maintain its operation. 1932 Huanghai chemical research institute was funded by boxer indemnity, the board director of China Education and Culture Fund, to explore the development of ammonium sulfate industry. 1933, Hou's English monograph The Manufacture of Soda Ash was published by American Chemical Society. This book reveals the century-old technical secrets of Soviets soda production, which has caused a sensation in the international academic circles and is recognized as a great contribution of China chemists to world civilization. Hou was awarded honorary membership by the British Chemical Society. 1934, Fan Xudong reorganized Li Yong Alkali-making Company into Li Yong Chemical Company, and expanded its business scope when the alkali-making industry was at the leading level. 1935, Li Yong Tancheng factory was established in Nanjing to produce ammonium sulfate and other chemicals. 1935, in order to solve the problem of brine refining in the production of pure alkali from Wynn Solvay, the Yellow Sea Research Institute of Chemical Industry successively adopted the salt washing method, drying method, lime soda method, lime mirabilite method and lime ammonium carbonate method, and finally decided to adopt the lime ammonium carbonate method. This method has simple equipment, conforms to the alkali production process and is a great contribution to the alkali production industry in China.
