Technology introduction: 1. Using cone calorimeter cabinet design, removable analysis ark, can be applied to the test using cone calorimeter, also can connect large heat release rate measurement system, conform to ISO 5660, ASTM E1354, GB/T16172 the current domestic and international test standard. 2. Integration test tank body and 19 inches analysis, embedded PC type 17 inch touch screen computer, used for the control and test process. 3. The conical rated power 5000 w heater, heat output 0 ~ 100 kw/m2, controlled by PID temperature controllers, radiation cone can be horizontal or vertical placed at the same time; 4. The center of the exposed surface of sample, within the scope of the 50 x50mm irradiation in the center deviation is not more than + / - 2%; 5. Sample box can be placed maximum 100 mm x 100 mm x 50 mm samples; 6. Sample weighing range is 0 ~ 2000 g; Accuracy: 0.1 g; 7. Cutting device of high voltage spark ignition system with safety generator, automatic positioning; 8. Paramagnetic oxygen analyzer, use the method to measure pressure changes of paramagnetic oxygen concentration in the gas. The concentration range of 0-25%, T90 < 1.5 s, zero drift: < < 0.5% / month, measured value migration 0.5% / month, linear error < 1% of the current measurement range; 9. CO and CO2 non-dispersive infrared analyzer CO: 0 ~ 1%; CO2:0 ~ 10%; 10. Laser system is used to measure the density of smoke, smoke density analysis system by photoelectric diode, 0.5 mW he-ne laser, the main graphics detector and the auxiliary graph of detector 11. The exhaust system, collect smoke cover by the fan and fan inlet and exhaust pipe and the orifice meter, etc. Exhaust fan flow 0 ~ 50 g/s adjustable, accuracy of 0.1 g/s; 12. The ring sampler shall be installed at 685 mm from collect smoke cover of air inlet pipe, the sampler should have 12 holes to homogenize the flow components; 13. 350 mm above the exhaust flow rate should be measured by the fan's sharp edges on both sides of the orifice differential pressure to determine, sharp edges of orifice diameter of 57 mm + / - 1 mm; 14. The temperature of the air flow should be 1.6 mm diameter closed nodes kai thermocouple measurements, thermocouple should be installed in the current 100 mm above the orifice plate; 15. Gas sampling system includes a ring sampler, sampling pump, filter, cold trap, wastewater discharge, water filter and co2 filter; 16. The cold trap: 0 ~ 5 degrees, diaphragm pump, flow rate: 26 l/min, vacuum degree: 700 ㎜ Hg, pressure: 2.5 bar; 17. Temperature control should be in the range of 0-1000 ℃ temperature automatic adjustment, control, set the resolution and accuracy of temperature control are two degrees, and should be with a thermocouple cold junction compensation device automatically. 18. Should choose cardan foil type heat flow meter, design range 0 ^ 100 k W/m ', the diameter of the radiation received target is 12.5 mm, surface covered with a durable glossy black coating. Radiation received target for water cooled. The heat flow meter accuracy is 3%, repeatability for 0.5%, with a calibration can be traced back to the NIST report.
