Title Using a modified water-glass binder to improve working conditions of casting knockout workers
Original title Primenenie modificirovannogo židkostekol'nogo svjazujuščego v celjah ulučšenija uslovij truda vybivščikov [in Russian]
Bibliographic information Jan. 1987, No.1, p.29-30. Illus. 5 ref.
Abstract The working environment in a casting knockout operation was studied in order to improve the safety and health of workers. The results were computer processed and a mathematical model was developed. By way of improvement it was suggested that the additives ammonium sulfate and sodium sulfite be used, which improve the strength of water-glass (sodium silicate) mixtures and facilitate knocking out. This measure decreases the physical work load of the operation and helps to bring down dust levels in the workplace air.
