Properties

The melting point of sodium Metasilicate Pentahydrate is 72.2℃,It is easily dissolved in water and difficult dissolved in ethanol and acid. The solution is slightly alkaline. It is easily to absorb moisture when it is stocked in the open air. It has characters of decontamination, decentralization, wetness, penetrability, and PH value buffer capacity.

Packaging and storage

Double bags, PE bag inside, PP bag or composite bag made of kraft paper and polypropylene braided fabric outside, with net weight of 25±0.2 kg. Alternatively, it may be packaged in other appropriate ways and with net weight of 1000/500kg. Don't store it in the open air. Avoid rain and direct sunlight and keep dry.
