Developing of dividing lube for concrete forms
Influence of concentration of various base oil additives on a wetting angle of lubricant compositions for forms of concrete products is investigated. Influence of wetting angle on lube operational characteristics is studied. The technique of an estimation of lubricant structure of a separation from the form is developed. Dependence of surface category from force of form separation is shown. Forces of form separation of the Russian and foreign lube analogues, base oils with additives, rapeseed oil, a ethyl ester of rapeseed oils are determined. Dividing lube for concrete forms is developed.
