Early strength of sodium metabisulfite as a water reducing agent in concrete

Sodium metabisulfite plays an early strength role in concrete. But the blending amount cannot exceed 0.1%-0.3%. If the added amount is too large, the later strength of the concrete will be affected. Fat-type water reducing agent is a kind of high water reducing and highly enhanced water reducing agent. It has the advantages of simple production process, short production cycle, and no three waste emissions during production and use. The main component of this product is sulfonated acetone formaldehyde condensate, which is formed by sulfonation and condensation of acetone, sodium sulfite (or sodium metabisulfite, plus alkali) and formaldehyde.

    Sodium metabisulfite is one of the important raw materials for the production of insurance powder, so our company has become the focus of attention for its preservation and transportation in high temperature weather.

    Here are some points for everyone, I hope to help you. For example, in the operation matters, it must be closed operation, strengthen ventilation. Operators must undergo special training and strictly abide by the operating regulations. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, and rubber gloves. At the same time avoid generating dust. Avoid contact with oxidants and acids. Handle lightly when handling to prevent damage to packaging and containers.

    For its packaging during transportation, we can use plastic woven bags lined with polyethylene plastic bags, net weight 25kg per bag. The package should be complete when loading and the load should be secure. During the transportation process, ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix and transport with oxidants, acids, edible chemicals, etc. Protected from rain and high temperature. The vehicle should be thoroughly cleaned after transportation.

    As for storage matters, try to store them in a cool, dry and well-ventilated warehouse. Keep away from fire and heat. It should be stored separately from oxidants, acids and edible chemicals, and avoid mixed storage. It should not be stored for a long time to avoid deterioration. The storage area should be equipped with suitable materials to contain the leakage. Storage and shelf life: shading, sealed and stored.
