Hydrofluoric acid, fluorosilicic acid, hydrochloric acid ........ So many "acids", do you know them all?

What is hydrofluoric acid?

Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, a clear, colorless, fuming corrosive liquid with a strong irritating odor. Because of its ability to dissolve oxides, hydrofluoric acid plays an important role in the purification of aluminum and uranium. Hydrofluoric acid is also used to etch glass, can be engraved patterns, marking scales and text; semiconductor industry uses it to remove oxides on the surface of silicon, in the refinery it can be used as a catalyst for the alkylation of isobutane and n-butene, to remove the surface of stainless steel, oxygen-containing impurities in the "dip acid" process will also be used in hydrofluoric acid. Hydrofluoric acid is also used in the synthesis of a variety of fluorinated organic compounds.

What is fluosilicic acid?

Before a long time ago, fluosilicic acid was mainly used for the production of sodium fluosilicate. With the continuous development and optimization of the comprehensive utilization technology of fluosilicic acid, fluosilicic acid has been applied to hydrofluoric acid and anhydrous hydrogen fluoride, low-density aluminum fluoride, magnesium fluosilicate, alkali-free quicklime and other product series, which opens up a new field of fluosilicic acid application, and fluosilicic acid has been widely used in building materials in recent years. In recent years, fluosilicic acid has also been widely used in construction materials. Fluosilicic acid is applied to alkali-free quick-setting agent, which can improve the stability of quick-setting agent, shorten the setting time of cement and enhance the adaptability of cement. In addition, fluosilicic acid is also used in metal plating, wood anticorrosion, beer disinfection and so on.

How much do you know about hydrochloric acid?

Hydrochloric acid is one of the important raw materials of chemical industry, widely used in chemical raw materials, dyestuff, medicine, food, printing and dyeing, leather, sugar, metallurgy and other industries. It is also used for the regeneration of ion exchange resins and as a cleaning agent for electroplating and metal surfaces.

Phosphoric acid is an important chemical raw material

Phosphoric acid is an important chemical raw material, the main role includes: as a metal surface treatment, in the metal surface to generate insoluble phosphate film to protect the metal from corrosion; and nitric acid mixed as a chemical polishing agent, used to improve the finish of the metal surface; the production of detergents, pesticides raw material phosphate; the production of phosphorus-containing flame retardant raw materials.

What is Glacial Acetic Acid

In different industries, glacial acetic acid has different uses, in the industry, glacial acetic acid can be used for synthetic dyes and inks; can be used in rubber and plastics industry, used as a solvent and starting material for many important polymers (such as PVA, PET, etc.) in rubber and plastics industry; used as a starting material for the composition of paints and adhesives; in the laundry is mainly manifested in the clothes play to prevent the loss of color, have a very strong removal of stains. It can neutralize acidity and alkalinity, but it should be noted that it needs to be used in accordance with certain instructions and not blindly. In chemistry, it is used as a descaling agent and rust remover; it can be used to synthesize cellulose acetate, which is used in photographic film and textiles.
