Problems solved by technology

[0004] In the prior art, the ball pressure test after heating is commonly used to test the heat resistance of non-metallic materials to obtain the change of its physical properties; or, directly test the temperature of spontaneous combustion or softening at high temperature, and obtain it through visual observation. As a result, there is no quantitative or qualitative result; or, the test function is relatively single, and it is impossible to accurately grasp the burning time and degree of non-metallic materials

Abstract

The invention discloses a device for testing the heat resistance of a nonmetal material, which comprises a base, a clamping mechanism, an electric heating device, a data acquisition system and a central processor. The data acquisition processing system comprises a temperature sensing assembly, a visible light sensor and a smoke sensor. The central processor is used for acquiring data signals of the temperature sensing assembly, the visible light sensor and the smoke sensor and sending a control signal to a control circuit of the electric heating device. According to the device, the burning temperature of the nonmetal material can be acquired; three burning states of only smoke generation (no open fire), detonation (mainly, open fire) and smoke and fire coexistence of the nonmetal material can also be acquired; the time from heating to burning and the burning degree of the nonmetal material can be accurately obtained; heat resistance data of the nonmetal material can be comprehensively and accurately acquired and is analyzed to obtain a qualitative and quantitative testing result, so that the accurate theoretical basis is provided for the application of the nonmetal material to the high temperature environment.

Description

technical field [0001] The invention relates to a material testing device, in particular to a device for testing the heat resistance of non-metallic materials. Background technique [0002] Non-metallic materials are materials composed of non-metallic elements or compounds. With the progress of production and science and technology, especially the development of inorganic chemistry and organic chemical industry, many new non-metallic materials have been manufactured and synthesized. Non-metallic materials have various Excellent performance, many of which are inferior to metal materials, so the use in modern industry continues to expand, and the scope of application is developing rapidly; it is widely used in high temperature, high pressure, corrosion, chemical, mechanical, pharmaceutical, military, aerospace and national defense fields, etc. Inflammable and explosive occasions; it has the advantages of low cost and light weight. [0003] Although non-metallic materials have...
