Device for testing fire resistance of fireproof plugging material and use method thereof

Abstract

The invention provides a device and a method for testing the fire resistance of a fireproof plugging material. The device comprises a fire resistance test furnace body, the test assembly comprises a material placement pipe, a to-be-tested material and a plurality of thermocouples, the to-be-tested material is accommodated in the material placement pipe, and the lower end of the material placement pipe penetrates through the upper end surface of the fire-resistant test furnace body from top to bottom and is communicated with a hearth at the upper part of the fire-resistant test furnace body; the probe end of each thermocouple is inserted into the material to be tested through the upper end of the material placement pipe, and the other end of each thermocouple is electrically connected with the temperature collector; the weighing piece is used for measuring the mass of the material to be measured; according to the device, the temperature change of the material to be tested in the test process is measured through the thermocouples, the mass change is measured through the weighing piece, and then the fire resistance of the material is analyzed. The device is simple in structure and convenient to operate, and the temperature and quality change conditions of the to-be-tested material along with time can be obtained at the same time.

Description

technical field [0001] The invention relates to the technical field of material fire resistance performance testing, in particular to a device for testing the fire resistance performance of fire blocking materials and a method for using the same. Background technique [0002] Cable fire blocking material is a new material for fire blocking of cable-intensive areas, mainly including: organic fire blocking material, inorganic fire blocking material and fire protection package, etc. Fire resistance, as the core parameter of fire blocking materials, is the focus of current fire detection. The refractory test furnace is an important device for the research and testing of fire-resistant sealing materials. The traditional refractory test is carried out directly through the refractory test furnace. It is impossible to observe the temperature change of the refractory material by storing the data, which cannot be observed in real time during the test. At the same time, the traditiona...

Problems solved by technology

The refractory test furnace is an important device for the research and testing of fire-resistant sealing materials. The traditional fire-resistant test is to test the refractory material directly through the refractory test furnace, which directly leads to the fact that it can only be transferred out of the test furnace after the test. The stored data is used to check the temperature change of the refractory material, which cannot be observed in real time during the test. At the same time, the traditional refractory test furnace can only obtain the change of the fireproof material over time, but cannot obtain the change of the quality of the fireproof material, and the quality of the fireproof material in the fire resistance test The change is also one of the important parameters to judge its fire resistance
