The waste is the by-product of Cold-box casting process in which a phenolic resin is mixed with sand, and the mold is made by blowing amine. Due to the use of a phenolic resin, this waste has the potential of being hazardous for the environment. As a result, it is necessary to implement reclamation on it prior to any application or landfilling.
sand, 1-2% of phenolic resin is added during molding as part I, the acidic agent i.e. aldehyde is added in between 40-45% of weight of phenolic resin. The curing agent required for this system is a strong sulfonic acid type, however, phosphoric acids is not able to permit fast curing of phenolic resins at the rate required for foundry applications.

This chapter focuses on resin bonded sand, which is widely available for making sand molds and cores. There are other inorganic binders such as cement, which was the earliest of the chemical binders to be used; ethyl silicate, which is used in the Shaw Process and for investment casting; and silica sol, which is also used for investment casting.
Process for producing resin-coated sand particles for use . Jun 08, 1976 · A process for producing resin-coated sand particles for use in shell moles wherein a phenolformaldehyde resin in an initial stage of condensation is sprayed into a hot zone to form droplets which gravitationally descend to a cold zone and solidify.

The resin sand casting process, conceptually similar to sand casting process, has peculiarities as the type of elements used in the making of the mold. It takes, phenolic resins and urea-furan which, together with a chemical catalyst, are mixed before forming to the sand.
In this article we study the reclamation technology of alkaline phenol formaldehyde resin bonded sand. We find that there are a lot of evaporation components in the alkaline phenol formaldehyde resin bonded sand, and they can be effectively removed by drying or baking.
This invention relates to a process for reclaiming ester-cured phenolic resin bonded sand. The process comprises contacting attrition reclaimed sand with a compound which converts potassium compounds to a form having a melting point of least 550° C., and then thermally treating the sand at a temperature below that which the resulting potassium compound fuses.

What is 'dry reclamation' There are three main types of reclamation systems: Wet, thermal, and mechanical. For the purpose of this editorial, the focus is on mechanical reclamation of silica sand, specifically for ester-cured alkaline phenolic systems. Dry reclamation is fast emerging as the most accepted way to reclaim no-bake systems.
Phenolic resin macromolecules were decomposed to methylbenzene, phenol, etc., and graphitic carbon and amorphous carbon appeared. The reason for the decomposition of phenolic resin molecules was presented. Nano-zerovalent iron, as an electron donor, transferred electrons to pentabromodiphenyl ether molecules during ball milling.
Poor collapsibility property of CO2 hardened sodium silicate bonded sand mold and phenolic urethane no-bake (PUN) binder system, made the reclamation of the sands more important.
