Abstract

The invention relates to an ignition device for a cone calorimeter. The cone calorimeter includes a shielding layer and an igniter. The shielding layer is connected with a driving mechanism that regulates its movement. There is a first control handle for adjusting and controlling the movement of the igniter. The driving mechanism includes a second control handle and a transmission assembly arranged between the second control handle and the shielding layer. The first and second control handles are hingedly connected to the frame respectively, and the igniter The first and second microswitches are arranged in series on the ignition circuit, and the first and second control handles are respectively connected with the first and second microswitches. In the above technical solution, by setting the first and second microswitches in series on the ignition circuit of the igniter and connecting the first and second control handles with the first and second microswitches respectively, the first control handle controls the shielding After the layer is fully opened, the igniter can be automatically started to ignite, ensuring the reliability of the ignition time and improving the accuracy of the experimental results.

Description

technical field [0001] The invention relates to the field of material performance testing equipment, in particular to an ignition device for a cone calorimeter. Background technique [0002] In recent years, new materials in construction and other fields have developed rapidly. When people pursue the excellent use effect of new materials, they often ignore that most of these materials are flammable materials, and there are great safety hazards in direct or indirect exposure to fire. Therefore, my country has successively National and industry standards for materials in different fields have been issued, and the flame retardant performance of various materials has been enforced. The flame retardancy of materials is generally tested in a cone calorimeter. [0003] According to the national standard GB / T16172-2007 "Test Method for Heat Release Rate of Building Materials", Article 11.3.3: The shielding layer must be removed within one second, and the igniter should be inserted a...
