Título Risk of electrostatic buildup during glue production
Título original Riziko elektrostatických nábojů při výrobě lepidel [en checo]
Información bibliográfica 1975, Vol.25, No.12, p.343-344. Illus. 10 ref.
Resumen This study is concerned with glues for the shoemaking industry, prepared from natural and synthetic rubbers or polyurethanes dissolved in commercial grade petrol or various combinations of toluene, acetone and ethyl acetate. The risk of formation of electrostatic charges is present mainly at the mixing stage. After stating the problem, the authors report the preventive measures taken in the undertaking concerned: earthing of all conductive parts of machinery; elimination of polyethylene in the packing material for the glue granulate; injection of solvents tangentially to the mixer wall by a non-sparking metal nozzle; improvement of conductibility of granulates by means of conductive additives which do not affect the properties of the end-product; maintenance of a moderate flow rate of the solvents in relation to the pipe diameter.
