Abstract
The invention relates to a textile material sample carrying table for a cone calorimeter. The textile material sample carrying table comprises a square box and a sample pressing frame corresponding to an upper end opening of the box. A supporting plate capable of moving vertically is arranged in the box. A screw rod is arranged in a screwed mode through a nut fixedly arranged in the center of a bottom plate of the box. The upper end of the screw rod is connected with the supporting plate through a bearing. A heat preserving brick in which a temperature sensor is embedded is arranged on the supporting plate. Inserting plates are arranged at the two sides of the bottom of the square box. The square box is inserted in a height adjusting frame through the inserting plates. A plurality of locating holes distributed vertically are formed in the height adjusting frame. By changing a clamping rod to penetrate into the different locating holes, the height distancing from a tested sample to a fire source can be adjusted; the distance between the tested sample and the temperature sensor is achieved by screwing and adjusting the screw rod. The protecting function of garment materials can be predicted by monitoring temperature changes at different distances between the tested sample and the temperature sensor. An effective test means is provided for analyzing the relation among factors influencing the protective property of shielding fabric.
Description
Technical field
The present invention relates to the experimental provision using cone calorimetry fire-fighting suit fabric to be carried out to thermal protective performance assessment, be specifically related to a kind of load sample platform of the tested textile material sample of carrying of modified node method.
Background technology
Cone calorimetry is the small scale fire test device for test material burning performance that America NI ST developed the beginning of the eighties in last century, and this instrument has modern design, tests the advantages such as easy and accurate.The appearance of cone calorimetry is the very important progress of fire test history of technique the next item up.ASTME1354, ISO5660-1 and ASTME1474 etc. are the standards about using cone calorimetry test material burning performance.The maximum feature of cone calorimetry is by the heat flow rate per unit area in taper well heater simulated fire, and material is burnt under accurate Fire Conditions, and energy is the multinomial dechforination in combustion such as the HRR of test material and the productive rate of burning gases simultaneously.Because the burning behavior of cone calorimetry test figure and vast scale fire test has correlativity, and cone calorimetry test is easier than vast scale fire test, economical, therefore, cone calorimetry test method(s) is more and more extensive in the application of the research field such as Fire Science, fire engineering and material be fire-retardant.
Cone calorimetry is all collected based on oxygen consumption principle and accurately measure the flow velocity of gas and the concentration of oxygen by all products of combustion in experiment, Heat liberation unit when just can calculate material combustion according to the change of oxygen concentration.
The composition of cone calorimetry, comprises the major parts such as load sample platform, taper well heater, laser tune cigarette system, cigarette ash measuring system, gas analysis system and data Collection & Processing System.When carrying out cone calorimetry test, ignited under the effect of the regulation heat flow rate per unit area that sample produces at taper well heater, the flue gas of generation is drawn out of under the deflation rate specified through gas skirt, gas exhaust duct; First gas analysis system sucks flue gas from sample tap, after filtration, imports gas analyzer after cooling and drying, and calibrated gas analyzer can be given vent to anger O in sample by Quick Measuring
2, CO
2with the substance withdrawl syndrome of CO, analysis result imports computer data processing system into after data acquisition system, and data handling system calculates HRR according to above-mentioned oxygen consumption principle, and CO
2with the productive rate of CO; Meanwhile, be fixed on the Laser Measuring cigarette system of exhaust duct both sides, according to the dim light of flue gas, measure the delustring area (amount of being fuming) during material combustion, mass loss rate during electronic scales synchronous recording sample combustion below sample cell.
The load sample platform that cone calorimetry is original-pack, mode only by adding and subtracting cushion block in process of the test carrys out the distance between adjusting sample (load sample platform) and taper well heater (burning things which may cause a fire disaster), and only play the effect supporting and hold sample, the Real-Time Monitoring to specimen temperature change and prediction skin burn time cannot be realized.
Summary of the invention
The object of the invention is to overcome fault of construction that original cone calorimetry load sample platform exists and expanding the test function of cone calorimetry, realize cone calorimetry to have and carry out Real-Time Monitoring and prediction garment material safeguard function to specimen temperature change, propose a kind of textile material load sample platform for cone calorimetry of improvement.
The present invention is used for the textile material load sample platform of cone calorimetry, comprise a square box and the magnetic pressure-like frame corresponding to this casing upper port, in described casing, arrange one can the supporting plate of vertical movement, by the nut being installed in box bottom center revolve put one can the screw mandrel of vertical movement, the upper end of screw mandrel is connected with described supporting plate by bearing, and supporting plate arranges the insulating brick that its inside is equipped with temperature sensor.
The plate extended along two side is provided with bottom described square box, by this plate, square box is plugged on height regulating frame, height regulating frame is provided with the pilot hole of several vertical characteristics, supports by the Ka Gang be plugged on this pilot hole the vertical height regulating square box.
The sidewall of described casing is provided with graduated scale and transparent window, to observe height residing for supporting plate.
The present invention is used for the textile material load sample platform of cone calorimetry, is set on different pilot holes by changing described Ka Gang, realizes the height regulating tested sample distance burning things which may cause a fire disaster; By tuning the distance that described screw mandrel realizes between tested sample and temperature sensor.By change and then the prediction that realizes garment material safeguard function of the thermograde under Real-Time Monitoring and sample different distance.For analyzing the relation of the thermal degradation of armored fabric and barrier propterty, air layer thickness and distribution to the impact of fabric thermal protective performance, provide effective research technique.
Therefore, the application of textile material load sample platform of the present invention on cone calorimetry, effectively extends the testing inspection function of existing general cone calorimetry.
