ТЕМПЕРАТУРНО-ВРЕМЕННОЙ ИНДИКАТОР

摘要

FIELD: measurement technology; medical engineering. ^ SUBSTANCE: device has flexible thermostatic base and temperature-sensitive coating containing pigment and binder agent. Mixed pH indicator is applied as the pigment composed of 4-dimethylamine-azobezene-2-carbonic acid and dyestuff. Polygraphic paint is used as the binder. The ingredients are taken in the following proportions in % by mass: pH indicator - 0.2-30.0 and polygraphic paint making the rest. Another embodiment of the invention comprises the composition with acid added with ingredients taken in the following proportions in % by mass: pH indicator - 0.2-11.0, acid - 7.0-25.0 and polygraphic paint making up the rest. ^ EFFECT: wide range of functional applications. ^ 9 cl
