How much is a ton of anhydrous sodium sulfate in Jingzhou? Market price of anhydrous sodium sulfate

The hydration product calcium sulphoaluminate is generated faster, thus accelerating the hydration and hardening speed of cement. The mixing amount of is generally 0.5%~2% of the cement quality, which can improve the early strength of concrete by 50%~. The 28 day strength sometimes increases, sometimes decreases, and the increase range is about 10%, which varies with the cement type, curing conditions and mixing amount. It is also used as the filler of synthetic detergent, as well as in paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.

Storage and transportation characteristics of sodium sulfate
Precautions for transportation: the package shall be complete and the loading shall be safe when starting transportation. During transportation, the container shall not leak, collapse, fall or be damaged. It is strictly prohibited to mix with acids, edible chemicals, etc. During transportation, it shall be protected from sun exposure, rain and high temperature. The vehicle shall be cleaned after transportation.
Precautions for sodium sulfate operation
Close operation and strengthen ventilation. The operators have been trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter type dust mask, chemical safety goggles, anti poison penetration work clothes and rubber gloves. Avoid dust generation. Avoid contact with acids. Handle with care to prevent package damage. Provide leakage emergency treatment equipment. Empty containers may leave harmful substances. When the dust concentration in the air exceeds the standard, wear a self-priming filter type dust mask. During emergency rescue or evacuation, you should wear gas mask.
Precautions for storage of sodium sulfate
Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. It shall be stored separately from acids, etc., and mixed storage is strictly prohibited. The storage area shall be equipped with appropriate materials to contain leakage.
