The thermal protection performance tester comprises a rack, a heating device arranged on the rack, a thermal insulation protection plate located above the heating device and a sample frame plate located above the thermal insulation protection plate, wherein the thermal insulation protection plate and the sample frame plate can be arranged on the rack in a rotatable or translatable manner; a sample fire passing through hole is formed in the center of the sample frame plate; the area of the thermal insulation protection plate is greater than that of the sample frame plate; the heating device comprises a fire head arranged towards the sample fire passing through hole; a heat dissipation device is arranged in the thermal insulation protection plate; the sample frame plate is provided with a heat insulation pressing and sensing plate for pressing a sample and sensing temperature of the sample; and the thermal insulation protection plate is provided with a temperature sensing part. The thermal protection performance tester provided by the invention has the advantages of simple and compact structure, comprehensive measured data, various measuring functions, accurate measured data, high measured data reference value, high temperature rising controllability, rapidness and stability, low energy consumption and energy saving.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a heat protection performance tester. Background technique [0002] The heating source of the existing detection device is often vacant, which may easily cause heat loss and uneven temperature in the heating area, and at the same time increase energy consumption and waste resources, and the existing single heating method increases the difficulty of temperature controllability. The accuracy of the data is low, and it is often necessary to repeat the detection many times to obtain more accurate data. At the same time, the existing detection device can only detect the time between two or three temperature differences at a fixed distance position, and the detection function is single. , The fire resistance test also needs another instrument for testing, and the data obtained by the sample test is not comprehensive. Contents of the invention [0003] The object of the present inv...
