The study of cracking of sheet polycarbonate by the method of exposure to its surface of adsorption active liquid media

Abstract

The effect of the composition of a liquid mixture of n-propanol with toluene on the rate of cracking in stressed polycarbonate sheets was studied. It is shown that the dependence of cracking time on stress can be described using equations in which the coefficient values depend on the ratio of the components of this test mixture. The method of wetting the surface of a sheet of monolithic polycarbonate with a test adsorption-active mixture (n-propanol with toluene) can be used not only to assess the quality of polycarbonate products, but also to measure the residual stresses in them. The conclusion is made that the influence of the investigated test liquid mixtures on the cracking of polycarbonate is multifactorial.
