China has a anti-corrosion coating market worth up to 200 billion. Judging from the regional distribution of heavy-duty anti-corrosion coating manufacturers, there are relatively many heavy-duty anti-corrosion coating manufacturers in Guangdong, Jiangsu, Shandong, Hebei, Liaoning, Hubei and other places. Neiqiu Xixin Resin Co., Ltd. (hereinafter referred to as "Neiqiu Xixin") is located in Hebei.
In order to seize market opportunities, Neiqiu Xixin decided to invest 34 million yuan to build an epoxy resin project with an annual output of 20,000 tons in Neiqiu Industrial Park (North Park), Hebei. On May 30, 2022, Neiqiu Xixin Resin Co., Ltd.’s annual 20,000-ton epoxy resin project was registered with the Neiqiu County Administrative Approval Bureau. html On June 23, the official website of the Neiqiu County People's Government announced the environmental impact report of the Neiqiu Xixin annual production of 20,000 tons of epoxy resin project.
The environmental impact assessment report pointed out that the Neiqiu Xixin epoxy resin project with an annual output of 20,000 tons covers a total area of 11.29 acres. It mainly builds factories, warehouses, comprehensive service office centers and other structures, and purchases reactors, storage tanks, tablet crushers, etc. Production equipment. The construction period of project is 6 months for . After the project is completed, it will be able to produce 20,000 tons of epoxy resin annually.
html The construction period of 620,000 tons of epoxy resin is only 6 monthsQutu (Qutu.com) learned that Neiqiu Xixin was established at the end of last year, and it has only been 7 months. The address is the North Park of Neiqiu Industrial Park, Hebei Province, and the south side of Weiyi Road. Its business scope includes the manufacturing of primary plastics and synthetic resins. Epoxy resin manufacturing and sales (excluding hazardous chemicals).
Through the environmental impact assessment report of Neiqiu Xixin, it is not difficult to find that Neiqiu Xixin and Hebei Xixin Resin Co., Ltd., an established resin manufacturer, are actually related companies.
Sky Eye Check shows that Hebei Xixin Resin Co., Ltd. was established in 2010, covering an area of 150 acres, with an investment of 220 million yuan, and an annual designed production capacity of 22,000 tons of epoxy resin and 6,000 tons of powder. The company is located in Guangzong Economic Development Zone, Hebei Province. With a superior geographical location and convenient transportation, it is currently one of the largest epoxy resin manufacturers in Hebei Province.
The 4,000-ton epoxy resin project completed by Hebei Xixin Resin Co., Ltd. in 2021 is going extremely hard. The preparation for the project began as early as 2011. If compared with this, the construction period of Neiqiu Xixin Construction's 20,000-ton-per-year epoxy resin project only lasted 6 months, which is not a smooth process.
The new project adopts the one-step method
It is worth mentioning that the Neiqiu Xixin annual output of 20,000 tons epoxy resin project bisphenol A uses epichlorohydrin , liquid chlorine , and bisphenol A three raw materials in one step. Synthesis, the process is simple.
In this regard, the environmental impact assessment report pointed out that Neiqiu Xixin relies on Hebei Xixin Resin Co., Ltd.’s many years of experience in the production of bisphenol A resin, and its technology is mature and stable.
According to disclosures, this epoxy resin project with an annual output of 20,000 tons uses epichlorohydrin and bisphenol A as the main raw materials, and uses a water washing process to produce solid epoxy through several processes such as polymerization, water washing, dehydration, cooling, crushing and packaging. resin. The production process of the project is intermittent production. The project builds 8 sets of polymerization production devices. Each set of production devices produces 4 batches per day, and each batch produces 2.08t of epoxy resin.
Interestingly, the epichlorohydrin used by Neiqiu Xixin will be directly produced by the company next door, Hebei Zhuotai Fertilizer Co., Ltd., and can be directly measured from the storage tank of Hebei Zhuotai Fertilizer Co., Ltd. by the metering pump . Pipelined to Neiqiu Xixin epichlorohydrin storage tank.
Reaction principle: The
project uses an alkaline solution to dissolve bisphenol A, and then adds epichlorohydrin. Under alkaline conditions, bisphenol A and epichlorohydrin undergo a polymerization reaction, and the reaction produces epoxy resin, water and chlorine. sodium. The remaining small excess of epichlorohydrin can produce complex organic compounds such as autopolymers and oligomers that exist as monomers (i.e., impurities). The main raw material consumption of the
project is as follows: the annual consumption of bisphenol A is 15,360 tons, the annual consumption of epichlorohydrin is 7,488 tons, and the annual consumption of liquid alkali (32%) is 10,176 tons.
The industry pointed out that epoxy resin refers to a resin compound containing at least two reactive epoxy groups in the molecule. Epoxy resin has many outstanding excellent properties after curing, such as strong adhesion to various materials, especially metals, strong chemical corrosion resistance, high mechanical strength, good electrical insulation, corrosion resistance, etc. . bisphenol A type epoxy resin is a polymer compound made by polymerizing bisphenol A and epichlorohydrin under alkaline conditions, washing and dehydrating. It has good physical and mechanical properties and chemical resistance. , electrical insulation properties, so it is widely used in coatings, fiberglass and other fields, and its development prospects are very broad.
