Introduction: The instrument is used to detect high-temperature expansion properties of solid inorganic materials and metal materials, especially corundum, refractory materials, casting and core materials, ceramics, ceramic raw materials, porcelain clay, glaze, glass, graphite, carbon Such as inorganic (organic) materials, metal products, polymer materials performance, scientific research, teaching provide the necessary testing methods. Through the instrument can be completed line variable, linear expansion coefficient, body expansion coefficient, thermal expansion, softening temperature, sintering kinetics, glass transition temperature, phase transition, density changes, sintering rate control (RCS) and their changes curve. GB / T16920-1997 glass - Determination of average linear thermal expansion coefficient. Features: A computer automatically calculates the expansion coefficient, body expansion coefficient, linear expansion, rapid thermal expansion. 2 Automatic calculation of compensation factor and automatic compensation, can also be manually corrected (online). 3 Automatically record, store, print number , print temperature - coefficient of expansion curve. 4 temperature spacing free to set the minimum spacing of 1 ℃. 5 can also root user requirements for the sample respectively for atmospheric protection, can be evacuated 6 imported linear bearings drive to achieve the expansion of friction-free transmission, transmission accuracy and repeatability. 7 The instrument is equipped with a standard computer interface, which can be connected with a general-purpose computer. All the test operations are completed by a computer interface, which is easy to operate and provides a full set of software.
