Water glass (sodium silicate)
Description
Casting (adhesive for casting mold) The foundry sand is mixed with sodium silicate solution, and it is hardened with CO2 after setting. This is called CO2 formula, or Dical powder and sodium silicate. Self-hardening method. Civil engineering, kiln industry civil engineering basic engineering, subway construction engineering, tunnel engineering, mineral mining, dam engineering, bridging, excavation, etc., mixed hardener or bentonite, widely used in strengthening construction sites and water stop applications. In addition, it is used for refractory and acid resistant Mortar binders and some refractory brick binders in the kiln industry.
