Introduction

Hydrofluoric acid is a kind of important chemical raw materials, its industry development and application field is extended to wider space, today's hydrofluoric acid industry has changed greatly from raw material to production technology, from application scope to environmental protection technology, so the research of hydrofluoric acid industry is important and complex. Through the analysis of the development status, production technology, application field and environmental protection technology of hydrofluoric acid industry, this paper studied the future development of hydrofluoric acid industry.

Hydrofluoric acid industry development status

Hydrofluoric acid is an important chemical raw material in chemical industry, and is widely used in electronic communications, energy chemicals, oilfield chemicals, chemicals, medicine and other industries. It has strong permeability and etching ability, which can be used for drilling, heat exchange and lubrication in oilfields, and is an irreplaceable raw material for wet etching and cleaning of precision electronic components. At present, the application of hydrofluoric acid is mainly applied to electronic communication products, such as circuit board insulation, capacitors, chips, etc., cleaning of quartz plating and metal parts, fluorocarbons, high performance Fluoroplastic production, and cleaning of materials such as glass and stainless steel.

The production technology of hydrofluoric acid industry

The production of hydrofluoric acid belongs to the fluorine chemistry industry, and the production process mainly includes fluorspar, sulfuric acid and hydrochloric acid cocrystallization, wet or dry fluoride refining and other processes. The raw materials of fluoride can be obtained from nature and produced synthetically. By leaching and refining or electrolysis, the raw material of hydrofluoric acid can be obtained from fluorspar. The main method of producing hydrofluoric acid from sulfuric acid and hydrochloric acid is actinolite cocrystallization, which needs to use certain reaction temperature and pressure during production. In addition, the dry method of producing hydrofluoric acid also needs to use certain reaction temperature and pressure, but the pressure is not very high.

Field application of hydrofluoric acid industry

Hydrofluoric acid is widely used in the electronics industry, including surface treatment of silicon wafers, etching of integrated circuits, production of plutonium oxide and electrical insulation. In addition, it is also widely used in the glass industry, as a glass etching agent for automotive windows, electric cooker glass refractory materials and special glass coatings, as well as for cutting high-viscosity glass films. In industry, hydrofluoric acid is used for non-electric hot dip galvanizing of iron and steel, treatment of automobile exhaust gases, production of aluminum fluoride, surface treatment of metal parts and production of electrical equipment. It is also used in the oil, chemical and pharmaceutical industries, and is an important component in the production of medical drugs and medicines.

Environmental protection technology in hydrofluoric acid industry

Hydrofluoric acid is a corrosive chemical, and its production process will produce a large amount of pollution. In order to reduce environmental damage, enterprises are making progress in environmental protection technology. Fluorine-producing enterprises have taken the lead in meeting the emission standards for air, water, solid waste and other environmental media. For example, the waste gas can be treated by chemical absorption or activated carbon absorption, or it can be purified by wet gas desulfurization, modified bag dust removal or scrubbing tower spraying tower method. In addition, industrial wastewater can be treated by chemical precipitation and coagulation method, and the solid waste produced in the production process can be recycled and reused.

Conclusion

Above is the research on hydrofluoric acid industry, and it can be seen that the hydrofluoric acid industry not only has a broad application field, but also has a wide range of raw materials, production methods and environmental protection technologies, and its development has a bright future. In the future development of the hydrofluoric acid industry, the key points will be the source of raw materials, the control of pollution, the development of advanced production technologies, and the study of new application fields, so as to promote the development of hydrofluoric acid industry in China.
