Introduction: JL-SPB-1 type gypsum board fire stability tester, also known as paper gypsum board fire stability tester, is used to determine the fire stability of refractory gypsum board, also applicable to other building materials, decoration, Determination of the fire resistance of decorative materials. Test Description: The sample is drilled and processed under specified environmental conditions. The sample is suspended by a strut between the two fire exits, and the fire exit is perpendicular to the surface of the sample. The liquefied petroleum gas is used as a heat source to supply gas to the two burners of the fire stability measuring instrument, and the burner firing port is 30 mm from the plate surface. The load is suspended at the lower end of the test piece according to the standard, and the burner is ignited. The temperature was measured with a thermocouple at a distance of 5 mm from the surface of the plate. At the beginning of the test, the carbonized protective paper dropped on the thermocouple should be removed without shaking the sample. By adjusting, the temperature was controlled at (800 ± 30) °C within 3 min, and this temperature was maintained throughout the test. From the start of the test piece to the fire, the test piece breaks and breaks. The time during which each test piece was blown was recorded, and the minimum of the five test pieces was taken as the fire stability of the set of samples, accurate to 1 min. Technical Parameters: 1. Power supply voltage: 220V±10% 50Hz Power: 180W 2. Automatic ignition function 3. Dual thermocouple temperature measurement 4. Temperature and time digital display 5. Double burner, inner diameter Φ9.5mm±0.5mm, length 100mm, air conditioning nut 10mm, fire head diameter (40±1)mm, fire hole diameter (2.5±0.1)mm 6. Flame length 20mm-100mm range adjustable 7. Flame application time and ignition time can be adjusted within the range of 0~99 minutes and 99 seconds. 8. The test process is automatically controlled. 9. The pattern breaks automatically records the burning time. 10. Gas source: The gas source of the test flame is gas or petroleum liquefied gas (it is recommended to use gas with better temperament as much as possible) 11. Flow adjustment range 100～1000mL/Min 12. Timing accuracy (resolution): 0.1s 13. Test temperature: 800±30°C, maximum temperature 900°C, accuracy level 1 14. Temperature stabilization time: <3min(800±30)°C 15. Specimen: 300mm (length) × 50mm (width), drilled separately from 25mm on both sides 16. Suspension load: 7, 10, 12, 15, 17, 20N 17. Dimensions (mm) 700 (width) × 300 (deep) × 600 (height) 18. Outer package size: (mm) 800 (width) × 420 (deep) × 700 (height)
