Granular Sodium Sulphate Anhydrous 99% For Metallurgy Strength Agent

Sodium Sulphate Anhydrous 99% applicate in building materials and metallurgy, used as an early strength agent for concrete and can accelerate the hydration and hardening of cement .

Sodium Sulphate Anhydrous 99% 

Main Application : 

1.It is used in the chemical industry to produce sodium sulfide

Sodium silicate water glass and other chemical products.

2. A cooking agent used in the papermaking industry for manufacturing sulfate pulp.

3. It is used in the glass industry to replace soda ash as a cosolvent.

4. It is used in the textile industry to formulate the coagulant for vinylon spinning.

5. It is used in non-ferrous metal metallurgy, leather and other fields.

6. It is used to make sodium sulfide, pulp, glass, water glass and glaze, and also serves as a laxative

And barium salt poisoning

Antidotes, etc. It is a by-product of the production of hydrochloric acid from table salt and sulfuric acid. It is used in the chemical industry to produce sodium sulfide, sodium silicate, etc. It is used in the laboratory to wash away barium salts. It is used as a raw material for the production of NaOH and H2SO4 in industry, and is also applied in papermaking, glass production, dyeing and printing, synthetic fibers, leather tanning, etc. In organic synthesis laboratories, miralite is one of the most commonly used post-treatment desiccants

7. It enables the hydration product calcium sulfoaluminate to form more rapidly, thereby accelerating the hydration and hardening speed of cement. The dosage of sodium sulfate is generally 0.5% to 2% of the cement mass. It can increase the early strength of concrete by 50% to 100%. The 28-day strength sometimes increases and sometimes decreases, with an increase of about 10%, which varies with the type of cement, curing conditions and dosage

8. It is used as an analytical reagent, such as a dehydrating agent, a digestion catalyst for nitrogen determination, and an interference inhibitor in atomic absorption spectrometry analysis.

9. It can be used as a buffer in sulfate galvanizing to stabilize the pH value of the plating solution .
