Calcium hydroxide Ca(OH) 2 reacts with sodium silicate Na 2 Si 2 O 3 and this provides the insoluble calcium silicate CaO*SiO 3. This is why the solution hardens right in the air! By the way, calcium silicate is a rather popular material for modern day industry. E.g. it is used for passive fire protection and in some types of cement. Disposal

Sodium Silicate Binders for Green Sand Metalcasting Foundry

The liquid sodium silicate is typically applied via a transfer roller, by cascading the diluted solution on the material surface or by immersing the material in the adhesive solution. Some manufactures prefer sodium silicate as an adhesive because it is low cost, non-toxic and environmentally friendly.

The invention discloses a preparation method for sodium silicate sand used for casting. The method comprises the steps of preparing modified sodium silicate and preparing molding sand, wherein, the modified sodium silicate is prepared by using a composite modifier which comprises 35 to 50% of talcum powder, 6 to 12% of starch, 14 to 18% of polypropylene glycol and 25 to 35% of nanometer ...

silica sand for sodium silicate in tanzania

Sodium silicate is known as liquid glass for good reason: When the water it is dissolved in evaporates away, the sodium silicate bonds into a solid sheet of glass. Heat tempering makes the silicate patch harder, but the solution can still be used for fireproofing wood and stain-proofing concrete if applied and allowed to dry at room temperature.
