Application: Sodium orthosilicate is used as an inorganic adhesive preparation ( can be mixed with talcum powder, etc. ), soap filler, and acid-resistant concrete. After adding pigments, Sodium orthosilicate can be used as a coating for external walls, and poured into the foundation soil of ancient buildings to make the soil strong to prevent collapse.
Properties: Sodium orthosilicate is a colorless crystal with a melting point of 1291K ( 1088 °C ). The water glass solution is alkaline due to hydrolysis. Carbon dioxide should be carefully prevented from entering during storage, and rubber stoppers should be used to prevent sticking to the mill glass plugs.
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.
