Production details:
The tester is designed to test rubber and plastic specimens of cord’s insulator or jacket. The tensile strength , elongation and hardness of dumbbell specimens before / after aging can be compared. This tester uses hot – air – circulation to make specimens aging. Its interior is sealed well and it is equipped with the induced draft device and auto shut-off protection if overheated.Inner air is changeable. Also can be used as a drying oven by introducing web-frame.
Main Functions:
.·Meet the test standard for GB/T2951, UL1581, Astm-D5423, VDC, CCC,
.·Apply to test the material aging in rubber , plastics, artificial leather and other chemical optimization.
.·Adopt high precision micro-computer and PID Auto-heating system, high accuracy of temperature control,
.·Adopted multi-blade centrifugal fan , and the device has forced air supply can ensure the internal temperature stable and even.
.·Hanger and Interlayer can free disassembly, the hanger rotating speed is 10 r/m,
.·Adopted the convenient air regulating system, easy to adjust the fresh air.
.·Provide bright and broad observation window, convenient to observe the experiment,
.·The inner box is processed with stainless steel at the mirror surface, the outside box is painted with electrostatic electrolytic plate ,
.·Multiple safety protection devices can ensure the machine running stable
