Biopolymer bindings for casting manufacturing processes on the technological lignin basis

Abstract

The paper analyzes the problem of using technological lignins to make new bindings for casting manufacturing processes. The reasons, restraining their application in casting manufacture, are considered. The objective (based on the physical nature of the material) and subjective (based on commercial benefit) reasons are presented. The paper considers the perspectives of application of technological lignins by the example of technological lignosulfonates use which is the main representative of the technological lignins family on the Russian market of bindings.
