Description
"Waterglass waste sand" refers to the waste sand material that is generated and discarded during foundry, refractory material or moulding-sand preparation processes when waterglass (sodium silicate) is used as a binder, owing to moulding-sand failure, strength reduction or process obsolescence. This type of waterglass waste sand is mainly composed of silica sand and residual sodium silicate; after crushing, screening, regeneration or stabilization treatment, it can enter the resource-utilization stage as recycled foundry sand, building-material filler or road engineering material.

Process Description
"Water glass waste sand" refers to the waste sand produced and discarded due to the failure of the molding sand, decrease in strength, or process obsolescence when water glass (sodium silicate) is used as a binder in casting, refractory materials, or molding sand preparation. This type of water glass waste sand is mainly composed of quartz sand and residual sodium silicate. After crushing, screening, regeneration, or stabilization treatment, it can enter the resource utilization chain as recycled foundry sand, building material filler, or road engineering material.
