Jun 13, 2010· Phenolic urethane binders work when a polyfunctional alcohol (part 1) reacts with a polyisocyanate (part 2) in the presence of a tertiary amine (catalyst) to create a urethane. In no-bake applications the catalyst for the reaction is a liquid amine; cold-box processes use atomized amines such as DMEA, DMIPA, or TEA in a nitrogen carrier gas.

Dec 15, 2017· Components of a Typical Cold Box Formulation In the cold box amine process, amines are used for the hardening of cores and molds. When investigating emissions in the foundry process, the solvents with a low boiling point that are used in part 1 and/or part 2 must be taken into account above all.
In the cold box method, a volatile curing catalyst (gaseous reagent) is passed through a shaped mixture of the foundry mix, usually in a core box, as opposed to a freestanding pattern mold. In this particular method of manufacture, the foundry mix must have adequate shelf life, meaning that it will not harden in the absence of a catalyst.
This binder is used in cold-box technology to produce foundry cores. ... Guide to managing risks associated with foundry work, April 2013. Archives of Foundry Engineering 15(SI4) (2015) 167-170.
Jul 19, 2012· A "cold box" process for forming a foundry shape by curing a binder in a foundry mix operates by sequentially introducing a first vaporous curing catalyst to a pattern containing the formed foundry mix, followed by introducing at least a second vaporous curing catalyst. By arranging the amounts of the respective vaporous curing catalysts and the contact times, as well as by using the …

Jun 07, 2013· In the "cold box" process, a foundry mix is prepared by mixing an appropriate aggregate with a binder. After forcing the foundry mix into a pattern, a catalyst vapor is passed through the foundry mix, causing it to cure and provide a foundry shape useful as a mold or core. ... the result will be a foundry mix characterized by a work time in ...
Cold-box, or gas-hardened processes introduce a gas to the core box which reacts chemically to harden the core binder. For example, sands enriched with furan resins or epoxies can be hardened by introducing SO 2. Water glass, or sodium silicate, can be hardened using the CO 2 process.

Mar 15, 2016· ACIDS The acid used is a sulfonate organic acid (methanesulphonic and similar), in water solution, chloride-free. There are four different types of acid (medium, weak and very weak): the choice of an acid is essentially conditioned by the sand temperature (in summer a weak acid is preferable, in winter a stronger one), but also by the type of sand, of resin and by the required hardening speed.
