Description
Technical field
The present invention relates to experimental provision of the cone calorimetry to the progress thermal protective performance assessment of fire-entry suit fabric is used, specifically
It is related to a kind of load sample platform of the tested textile material sample of carrying of improved structure.
Background technology
Cone calorimetry is the small ratio for test material combustibility that U.S. NIST develops in the beginning of the eighties in last century
Example fire test device, the instrument have the advantages that novel in design, test is easy and accurate.The appearance of cone calorimetry is fire
The very important progress of experimental technique history the next item up.ASTM E1354, ISO5660-1 and ASTM E1474 etc. are relevant uses
The standard of cone calorimetry test material combustibility.The maximum feature of cone calorimetry is by taper heater simulated fire
In heat flow rate per unit area, the material is burnt under quasi- Fire Conditions, can test material simultaneously HRR and burning gases
The multinomial dechforination in combustion such as yield.Because cone calorimetry test data and the burning behavior of large scale fire test have phase
Guan Xing, and cone calorimetry experiment is easier than large scale fire test, economical, therefore, cone calorimetry test method(s) is in fire section
Learn, the application of fire engineering and the research fields such as material is fire-retardant it is more and more extensive.
Cone calorimetry is all to collect combustion product all in experiment based on oxygen consumption principle and accurately measure
The flow velocity of gas and the concentration of oxygen, so that it may Heat liberation unit when calculating material combustion according to the change of oxygen concentration.
The composition of cone calorimetry, including load sample platform, taper heater, laser adjust cigarette system, cigarette ash measuring system, gas
The major part such as analysis system and data Collection ＆ Processing System.When carrying out cone calorimetry experiment, sample heats in taper
It is ignited in the presence of regulation heat flow rate per unit area caused by device, caused flue gas is through gas skirt, discharge duct in defined exhaust speed
It is extracted under rate；Gas analysis system sucks flue gas from sample tap first, and gas analysis is imported after filtered, cooling and drying
Instrument, calibrated gas analyzer can quickly measure O in gas sample2、CO2With CO substance withdrawl syndrome, analysis result is through data
Computer data processing system is passed to after acquisition system collection, data handling system calculates heat release speed according to above-mentioned oxygen consumption principle
Rate, and CO2With CO yield；Meanwhile the Laser Measuring cigarette system of exhaust duct both sides is fixed on, according to the dim light of flue gas, survey
Determine the delustring area (smoke amount) during material combustion, mass loss during electronic scale synchronous recording sample combustion below sample cell
Speed.
The original-pack load sample platform of cone calorimetry, it is only capable of by way of adding and subtracting cushion block (carrying come adjusting sample during experiment
The distance between sample platform) and taper heater (burning things which may cause a fire disaster), and only serve support and hold the effect of sample, it can not realize to sample
The real-time monitoring of temperature change and prediction skin burn time.
The content of the invention
The invention aims to overcome fault of construction existing for original cone calorimetry load sample platform and extend taper amount
The test function of hot instrument, realize that cone calorimetry has and specimen temperature change is carried out to monitor and predict that garment material is prevented in real time
Protective function, propose a kind of improved textile material load sample platform for cone calorimetry.
The present invention is used for the textile material load sample platform of cone calorimetry, including a square box and corresponding to the casing upper end
Mouthful magnetic pressure-like frame, in the casing set one can vertical movement supporting plate, by the spiral shell for being installed in box bottom center
Mother's rotation put one can vertical movement screw mandrel, the upper end of screw mandrel is connected by bearing with described supporting plate, and one is set on supporting plate
Its internal insulating brick for being equipped with temperature sensor.
The plate extended along two side is provided with the square box bottom, square box is plugged on by height by the plate
Spend on adjusting bracket, the positioning hole of several vertical characteristics is provided with height regulating frame, passes through the Ka Gang being plugged on the positioning hole
The vertical height of support regulation square box.
Graduated scale and transparent window are provided with the side wall of described casing, to observe height residing for supporting plate.
The present invention is used for the textile material load sample platform of cone calorimetry, and different positioning is set in by changing the Ka Gang
Kong Shang, realize height of the regulation tested sample apart from burning things which may cause a fire disaster；Tested sample and TEMP are realized by the screw mandrel for tuning described
Distance between device.It can be realized by monitoring in real time with the change of the thermograde under sample different distance to garment surface
Expect the prediction of safeguard function.To analyze relation, air layer thickness and the distribution of the thermal degradation of armored fabric and barrier propterty to knitting
The influence of thing thermal protective performance, there is provided effective research technique.
Therefore, application of the textile material load sample platform of the present invention on cone calorimetry, existing general cone is effectively extended
The testing inspection function of shape calorimeter.
