LFY-637 Paving Material Combustion Performance Tester (Radiant Heat Source Method)
The main purpose
It is suitable for various floor covering materials, such as textile carpets, cork boards, wood boards, rubber boards and plastic floors and floor spraying materials. The result can reflect the tender burning performance of the floor material (including the base material). The test method is to ignite the floor material placed horizontally and exposed to the inclined heat radiation field with a small flame in a test combustion box to evaluate the material Flame propagation ability.
Instrument characteristics
1. The whole process of the test is controlled by computer, with a high degree of automation.
2. Automatic ignition, automatic timing, display of radiation flux curve, data processing,
Save and print test reports.
3. With air leakage alarm protection system.
Technical index
1. Radiant heat source: the size of the radiating surface is (300×450)mm±10mm, and the radiant panel can withstand a high temperature of 900℃.
2. Specimen fixture: made of fire-resistant L-shaped stainless steel with a thickness of (2.0±0.1) mm, and the size of the exposed surface of the specimen is (200±3) mm×(1015±10) mm.
3. Igniter: a stainless steel igniter used to ignite the test piece, with an inner diameter of 6mm and an outer diameter of 10mm. There are two rows of holes on the igniter, and 19 radial holes with a diameter of 0.7mm are evenly distributed on the center line. Under 60. 16 radial holes with a diameter of 0.7mm are evenly distributed on the line.
4. Propane flow controller: The flow of propane gas is controlled at (0.026±0.002) L/s, and the ignition flame height is guaranteed to be (60～120) mm.
5. Smoke removal: smoke exhaust speed: (2.5±0.2) m/s;
Smoke exhaust capacity: 39～85 m3/min;
The hot ball anemometer measures the flow velocity of the exhaust channel with an accuracy of ±0.1 m/s;
6. Water-cooled heat flux meter: measuring range of heat flux meter: 0～15Kw/m2;
Accuracy of heat flux meter: ±0.2Kw/m2;
Heat flux meter accuracy: <±3%
7. Temperature sensor: Two K-type stainless steel thermocouples with a diameter of 3.2 mm. They are installed in the floor material radiation test box and the flue at (150±2) mm from the top of the flue flue.
8. Radiation pyrometer: the test range is (480～530)℃ (black body temperature), the accuracy is ±0.5℃, the distance between it and the radiator is about 1.4 m, and the sensitivity of the radiation pyrometer is constant within the wavelength range of 1μm to 9μm .
9. Power supply: Power supply voltage: AC 220V±10%, 50Hz; maximum operating power: 5kW;
