Product introduction:
The UL910/NFPA262 steiner tunnel furnace is mainly used for testing the flame retardant performance of CMP grade wire and cable. It is mainly used for laying the cable directly in the ventilation or forced ventilation environment without metal pipeline in the horizontal subsystem.The flame retardant test standard represents the strictest flame retardant test standard for UL and even the whole wire and cable. Only the fluorine sheath cable can pass the flame retardant test method.Due to its high decomposition temperature (over 400 degrees) and high ignition point (over 800 degrees), fluoroplastic is not easy to burn in a small fire, so it has better fire resistance than other organic materials.
Technical parameters:
1. The combustion chamber is made of stainless steel, with firebrick laid inside.Good insulation.The inner dimensions of the combustion chamber are 305mm x 451mm and 7.6m long.
2. The internal tools and fixtures are made of SUS304 stainless steel, rust and corrosion resistant.
3. Double-layer quartz glass observation window can observe the flame spread distance, and display the flame advance position through the indicator light, which makes the recording more intuitive.
4. The height of the combustion chamber is suitable for people to watch the combustion state and install, and adjust the sample;
5. The combustion box cover is designed as a whole, and the tank seal is designed according to the standard. The tank is equipped with the stainless steel water seal of 2mm thick to ensure that the smoke will not leak during the test.
6. The box cover is made of refractory materials and stainless steel. The box cover is equipped with a hook and a hoisting cover device.
7. The sample holder is equipped with cooling water circulation support bracket, which is resistant to high temperature and can support combustion coverings such as calcium silicate plate.
8. SUS304 stainless steel upper cover of the insulation body, filled with heat-resistant insulation materials
9. Provide escalator-type sample installation platform for easy installation, installation and removal of samples and overhaul of furnace tube;
10. Stainless steel smoke exhaust pipe, beautiful and corrosion-resistant;
11. Independent and multi-functional exhaust pressure testing device: real-time monitoring of exhaust pressure changes during testing.Test range: 0 ~ 250Pa; accuracy: 0.5pa; system pressure:±2Pa
12. Fan: 380V, 50Hz and 3Kw are equipped with frequency converter to change the wind speed.The maximum flow rate shall be at least 8000m3/h, which can timely discharge the flue gas generated under the severe combustion of the sample out of the room to ensure the safety of the test;
13. Dual-head copper gas burner: the burner is 1320mm away from the air inlet, and can output the heat of the standard 5.3mj /min. The gas flow can be controlled by the mass flowmeter according to different standards.
14. Automatic ignition system: ensure the safety performance of the test, high-pressure ignition, 12KV, 50mA, and the minimum high pressure of ignition electrode is 1.8kvp;
15. Smoke density system: a separate signal processing system is provided to ensure that the sensor is linear;
16. Automatic recording of temperature and flue gas sensor signals, sample acquisition frequency of 1Hz;
17. Mass flow controller:SUS316 stainless steel material, the maximum pressure of 1000 psi (70 bar), the leakage rate is less than 1 x 10-7 ml/s, the NIST calibration, 0 ~ 5 VDC and 4 ~ 20 ma signal, circuit protection, propane flow range 0 ~ 2.3 g/s, 2 s or less control speed, the range of 0.6 ~ 2.3 g/s control accuracy of plus or minus 1% FS, repetitive ± 0.5 FS, temperature range of 0 ~ 50 ºC, humidity range of 0 ~ 90%, digital display, automatic control test in the process of gas supply to meet 5000 btu (MJ) 5.3 / min quantity of heat,The software automatically records the amount of gas used;
18. Standard test software can automatically record the wind speed, temperature, smoke density and other test data of the system.
Auxiliary equipment:
1. Self-supplied water system
2. Methane combustion gas system
3. Hoist system
