Properties: Pure sulfuric acid is a colorless transparent oil-like liquid with a specific gravity of 1.82 -- 1.84 at room temperature, boiling point of 270℃, freezing point of 10.4 ℃. It can be mixed with water in any proportion. The corrosion is very strong, concentrated sulfuric acid has a strong water and oxidation.
Technical indicators
The qualified product sulfuric acid should meet GBT534-2002 standard, the index is sulfuric acid (H2SO4) quality percentage is greater than or equal to 92.5% or 98.0%, ash quality percentage is less than or equal to 0.10%
To use
Sulfuric acid is the basic chemical raw material used in the manufacture of chemical fertilizers, inorganic salts, man-made fibers, plastics, organic dyes and petroleum refining, etc. It is used in the manufacture of various explosives in the national defense industry, and a large amount of sulfuric acid is also used in metal processing and non-ferrous metal smelting in the metallurgical industry
Safety technical specification
Sulfuric acid burns make skin protein denaturate and solidify, which must be handled timely on site and every minute counts. Generally, the following principles should be observed:
1. Get the casualty out of the accident spot immediately
2. General burns first with a large amount of water continuous washing, the clothes, shoes and so on with sulfuric acid quickly removed straight to the trace of sulfuric acid disappeared
3. If the burn area is too large, the patient should lie on his back and keep warm all over the body. When the critical symptoms improve, the patient should be sent to hospital for treatment immediately
4. If the sulfuric acid splashes into the eye, it must be immediately rinsed with a large amount of water (no pressure) under the eyelid open and open under the condition of continuous 15 minutes, the eyelid and all the areas of the eyeball rinse
5. Do not apply oily or greasy medicine to the wound without the doctor's instruction.
