Chemical production of hualin

194 1 At the beginning of the year, in order to break the blockade of the Japanese invaders, the commander of the left-behind corps of the 18th Army asked Yan 'an Academy of Natural Sciences to complete the task of producing glass, and Xu Teli, the president, handed this task over. Hua Lin has never been engaged in glass production technology and lacks knowledge. However, inspired by the Yan 'an spirit of self-reliance and hard struggle, he braved difficulties and went forward bravely. Besides borax, he found that there are also raw materials for glass production in the border region, such as the raw materials for extracting soda ash in the northwest of Jinpenwan, limestone in Dufuchuan, clay in Qiaoergou and Wayaobao, and nitrate is everywhere. Another problem is the lack of technical conditions for producing glass. At this time, the Academy of Natural Sciences got more than 80 boxes of chemicals and instruments from China Alliance led by Soong Ching Ling, which provided technical conditions for the development of glass. Then there is the problem that there is no crucible for burning glass. Under the guidance of Dean Xu Teli, Hualin learned from craftsmen and consulted kiln workers. After repeated experimental analysis and theoretical discussion, she finally made a crucible that is resistant to high temperature and not easy to crack. After countless sleepless nights, Hua Lin and relevant personnel finally developed this kind of glass. Workers blow glass into pipes, bottles, lampshades, needles and test containers for military and civilian use. At the beginning of 1943, in order to expand glass production and solve the problem that refractory materials are urgently needed for ironmaking, Qiaoergou Ceramics Factory under the Military Bureau of the Border Region became a glass ceramics factory, and Hualin worked as an engineer in the factory. 1 year, he and his colleagues manufactured a complete set of ceramic equipment for producing sulfuric acid, hydrochloric acid, nitric acid, concentrated sulfuric acid and smokeless powder in this factory, which strongly supported War of Resistance against Japanese Aggression. At the beginning of 1945, Hua Lin went to Wayaobao Northwest Iron Works as the factory director, responsible for organizing coal mining, coking and building ironmaking blast furnace. In just half a year, coal was mined and half a blast furnace was built. When everyone was building factories around the clock, there came the good news of War of Resistance against Japanese Aggression's victory. Hualin was ordered to end the work of Wayaobao and took part in the work of the Military Industry Bureau led by Liu Ding. On the way to the northeast, Hua Lin and his party went through many twists and turns due to the influence of the war, and did not arrive in Dalian until the end of 1946. When he was the deputy director of Dalian Chemical Plant, he spent more than half a year organizing the recovery of nitric acid and sulfuric acid production. During 1947, Hua Lin and Zhang Dingyi visited the coal mine, power plant and Harbin factory of Jixi Mining Bureau in the Industrial and Mining Department of Northeast Economic Commission to promote the recovery and development of production. In order to solve the problem of lack of copper materials in these factories and mines, they also went to Tianbaoshan Copper Mine in Jilin to recruit workers and resume copper production.

1April, 948, Jilin was liberated, and Hualin was ordered to work in Jilin Chemical Industry Zone. At that time, the former Japanese puppet Jilin Electrochemical Company in the east of the chemical industrial zone had the remaining coal washing plant, 38-hole coking furnace and large calcium carbide furnace shell; There is an unfinished methanol gasifier in the petrochemical plant of the former Japanese military department in the west. The equipment in the chemical industry zone was transported away by the Soviet Union, and the factories and dormitories were destroyed and burned by the Kuomintang army. The chemical industrial zone is in ruins. Hualin lives in the home of an old worker, publicizes the policy of self-reliance to resume production, and makes plans to recruit workers and donate equipment. The scattered workers came back after hearing the news. They rely on a few wagons of corn shipped from Harbin to solve the problem of workers' meals. By recruiting technicians and old workers, the factory management organization was established. In half a year, the number of employees has increased to 800. After living in the conquered nation for more than 10 years, all the workers worked hard and full of energy, working day and night, and soon resumed the production of calcium carbide and yellow phosphorus workshops.

While Jilin Chemical Industry Zone resumed production, Hualin actively carried out investigation and research. He deeply felt that Jilin Chemical Industry Zone has good natural and economic conditions, with a length of more than 20 kilometers from east to west and a width of 3-5 kilometers from north to south. There are expressway and special railway lines. Songhua River, which flows through the chemical industry zone, is rich in water, good in water quality and low in water temperature, which is very suitable for chemical production. There is Fengman Hydropower Station in the upper reaches of Songhua River, and there are two remaining 70,000 MW units, which can generate electricity after repair. In a word, there are good conditions for developing chemical production here. For this reason, Hualin has repeatedly put forward ideas and suggestions for developing chemical production.

1948165438+10. In October, Hualin was ordered to lead more than 80 employees of Jihua to Shenyang to receive Shenyang Chemical Plant, Shenyang Paint Plant and Shenyang Grease Plant, and then take over Jinzhou Synthetic Oil Plant, Jinxi Chemical Plant and Huludao Sulfuric Acid Plant located in western Liaoning. Under the leadership of Hualin, chemical plants in Jilin and Liaoning resumed production one after another, which not only supported the War of Liberation, but also laid the foundation for the great development of People's Republic of China (PRC) after its founding.
