reclamation - Opis:
- For the reasons of environmental problems connected with the use of furan binders the attention is increasingly paid to self-setting mixtures with alkali resols. A resol binder stabilized with KOH, NaOH is hardened by liquid esters with the formation of alkaline salts. The increase of their concentration affects the shortening of the mixture bench life, it decreases strength, abrasive wear of moulds and cores is growing, and it results in uneconomical dilution of the reclaim with expensive new base sand. Length of life (bench life) of mixtures plays an important role just in manufacture of huge and voluminous moulds and cores in self-setting mixtures. This contribution aims at analyzing the function of reactive alkaline salts in the reclaim, it monitors consequences of its thermal exposure on properties of self-setting mixtures, and it deals with development of methods evaluating its qualities.
