The prospects are vast! Juhua Accelerates the Layout of This Fluorine Containing New Material!
On July 18th, the environmental impact report of the 4000 ton/year TFE downstream high-end fine product technology renovation project of Zhejiang Jusheng Fluorine Chemical Co., Ltd. was announced.
It is understood that Zhejiang Jusheng Fluorine Chemical Co., Ltd. plans to invest approximately 80 million yuan to build a 3200t/a hydrofluoroether (HFE) series of products, bringing the total production capacity of fine products to 4000t/a. This project mainly adds 800t/a tetrafluoroethyl methyl ether (HFE-254), 400t/a tetrafluoroethyl tetrafluoropropyl ether (D2), 1500t/a tetrafluoroethyl trifluoropropyl ether (D3), and 500t/a tetrafluoroethyl octafluoropentyl ether (D4). The original 400t/a tetrafluoropropanol (TFP) and 400t/a hydrofluoroether are added.
Zhejiang Jusheng Fluorochemical Co., Ltd. (hereinafter referred to as Jusheng Company) was established in July 1994, located in the Sino Russian High tech Industrial Park of Juhua Group Co., Ltd. in Quzhou, Zhejiang. It was jointly established by Juhua Group Co., Ltd. and the Russian National Applied Chemistry Research Center, with a registered capital of 12 million US dollars.
At present, Jusheng has many grades of products, such as PTFE suspension fine powder, suspension medium particle, suspension granulation, suspension pre sintering, dispersion fine powder, concentrated dispersion solution, modified dispersion fine powder, modified dispersion lotion, etc., with complete grades and brands, and the performance is equivalent to that of imported resins. Among them, suspension granulation and suspension fine powder fill the domestic gap and are recognized as national key new products.
About hydrofluoroether
1、 Introduction to hydrofluoroether
Hydrofluorinated ethers (HFEs) are ether compounds composed of carbon, hydrogen, oxygen, fluorine and other atoms. They have high volatility, low thermal conductivity, low surface tension, and low flammability, and can be used as refrigerants, cleaning agents, and foaming agents. Since there are no ozone depleting chlorine and bromine atoms, ODP is zero, GWP is low, and the residence time in the atmosphere is short. Following Hydrofluorocarbon, HFEs are considered to be one of the ideal alternatives to Chlorofluorocarbon and hydrogen Chlorofluorocarbon.
In addition to its excellent environmental properties, hydrofluoroether also has excellent thermal and chemical stability, moderate solubility, low toxicity, non corrosiveness, non combustion, no smoke generation, and good material compatibility. It is easy to store and transport, and is widely used in many fields such as medicine, electronics, metals, precision instruments, optical lenses, communication, and aerospace.
However, the dielectric constant of hydrofluoroether is relatively high, with values far greater than 2.5. The reason for this is the high molecular polarity, which increases its dielectric constant. At present, hydrofluoroether is mainly used in fields where the dielectric constant requirements are not very strict.
The synthesis technology of hydrofluoroether has been monopolized by foreign countries for a long time, and the high product prices have become a "bottleneck" problem that restricts the development of China's fluorine chemical industry. Domestic enterprises have made tremendous efforts to achieve the industrial production of various hydrofluoroethers. Currently, the main production enterprises include Juhua Group, Changlu New Materials, Jiangxi Zhongfu Group, New Zebang, etc.
2、 Application of hydrofluoroether
Hydrofluoric ether can be used in fields such as cleaning agents, refrigerants, solvents, foaming agents, electrolyte additives, etc.
1. Cleaning agent
Due to the strong electron absorption ability of fluorine atoms, hydrofluoroether can clean both non-polar organic pollutants and polar inorganic pollutants; Moreover, its surface tension and viscosity are relatively low, and it is easily volatile without residue, making it widely used in the following fields:
(1) Clean precision instruments such as circuit boards and picture tubes;
(2) Clean LCD/OLED displays, optical components, and lenses;
(3) Clean the semiconductor etching chamber and parts;
(4) Remove residual fluoride deposits;
(5) Clean car engine parts;
(6) Clean communication equipment, aviation engines, and oxygen pipeline equipment;
(7) Clean medical equipment parts, etc.
However, in most cases, hydrofluoroether needs to be mixed with other azeotropes to achieve better cleaning results.
2. Solvent
As a solvent, hydrofluoroether has low viscosity and surface tension, is easy to evenly diffuse and wet, and is easy to quickly dry, non flammable, and has good material compatibility. It can be used in the following fields:
(1) Media for air tightness testing and voltage resistance testing;
(2) Electronic coating and screen coating diluent;
(3) Fluorine oil, fluorine resin, fluorine coating diluent;
(4) Flame point regulator for flammable solvents;
(5) Reaction solvents and extraction solvents for analysis.
3. Refrigerant
Hydrofluorinated ethers have excellent electrical properties, a wide range of applicable temperatures, low absolute viscosity in the ultra-low temperature range, non combustible, high chemical stability, and good material compatibility. They can be used as refrigerants, mainly including:
(1) Temperature control refrigerant for dry etching devices, photolithography devices, ion injection devices, probes, and information processing devices;
(2) Immersive refrigerant in data centers;
(3) Immersive refrigerant for power devices;
(4) Food industry cooling devices, freeze-drying, freezing and crushing of rubber and plastics, chemical industry grade pharmaceutical industry cooling devices, etc.
