METHOD OF NON-DESTRUCTIVE DETERMINING TEMPERATURE CHARACTERISTICS OF STRUCTURAL TRANSITIONS IN POLYMERIC MATERIALS

摘要

FIELD: test engineering.SUBSTANCE: body under study is brought into thermal contact with the reference body in the plane in which the local circular heater is located. At regular intervals of time the difference of values of the temperature between the heater and the point of plane of contact of the body under study and reference body is measured. The tests end up in excess of the specified value by the controlled dynamic parameter. The dependence of the current value of thermal activity on the temperature of the body under study is made. The structural transitions in polymeric materials are determined by the presence of peaks on dependence of the current value of the thermal activity on the temperature of the body under study.EFFECT: improved method.9 dwg
