Gulvbelægning Radiant Panel Tester
Gulvbelægning Radiant Panel Tester rustfrit stål Test Box Can Records den Flame Spread Tid af sig selv
Produkt Profil of Gulvbelægning Radiant Panel Tester
ISO 9239 Radiant Gulvbelægning Panel test er hjørnestenen i gulvmaterialer reaktion på brandtests i Euroclass systemet. Testen måler flammespredningen af prøven under termisk eksponering ved anvendelse af en strålevarme antændelseskilde. Den termiske eksponering er, at en brand vokser i lokale, svær en døråbning, udstråler onto gulve i et tilstødende rum eller korridor. Apparatet kan også anvendes til prøvning standarder ASTM E648 og DIN 4102; Del 14.
Strålingen testeren af belægningsmateriale anvendes til at måle den kritiske varmestråling flux af formalet beklædningsmateriale. Den kritiske Strålingsfluxen refererer til den indfaldende varme per arealenhed. Jo større den indfaldende varme, jo højere den krævede opvarmning mængde materiale, den mere stabile materialet er, og jo mindre mulighed for antændelse. I denne test enhed, bliver en termisk strålingskilde og en T-type brænder installeret. Jo længere prøven er fra strålingskilden, flux jo lavere varme stråling modtaget på overfladen. Prøven antændes af en T-type brænder. Skaden afstand af prøven efter flammen slukkes måles, og den tilsvarende varmestråling flux værdi, dvs. kritisk varmestråling flux, måles.
Funktionskendetegn af Gulvbelægning Radiant Panel Tester
1. rustfrit stål testboks vedtager hoveddøren design, som er praktisk til rengøring af indvendige væg af kassen.
2. The inner wall of the box is calcium silicate plate, which can prevent high temperature and corrosion.
3. Stainless steel smoke collector, as for the upper part of the combustion test box;
4.300mm X 450mm porous ceramic thermal radiation plate, placed at 30 degrees angle;
5. Provide T-type porous burner, apply open fire to the sample and adopt cylinder driving mode.
6. The optical system consists of an incandescent lamp with a light source of 2900 +100 K color temperature and a silicon light diode as the light source.
7. A shutter is installed at the front end of the silicon light-emitting diode, which can be opened and closed automatically by computer testing software for easy calibration.
8. Rotor flowmeter adjusts the flame height of T-type burner.
9. Propane mass flowmeter adjusts the gas flow rate of radiation plate and displays it digitally.
10. Self-contained blower provides air source and passes Venturi mixture test gas.
11. Mass flow controller is used to adjust the intake flow of radiation plate.
12. SB water-cooled heat flow meter, working range is 0-50 kW/m2, the accuracy of heat flow meter is less than 2%, response time is 0.2 s. It provides portable cooling water source without external water.
13. The user can move the heat flow meter to calibrate the radiation flux of the radiation plate conveniently. At the same time, the test software can draw the standard heat radiation flux curve.
14. It is equipped with pedal switch. According to the flame spread distance, users can acquire the flame spread time to reach the test distance. At the same time, the computer records the flame spread time by itself.
15. Install one chimney thermocouple and one thermocouple in the box, which can be displayed by computer software.
16. Equipped with infrared radiometer, the temperature of radiation plate can be detected and displayed by computer software.
17. Equipped with 15 inch industrial touch screen computer, users can monitor the whole combustion test process through the test software.
18. The software can display the data of heat radiation flux, smoke density curve, transmittance curve and wind speed.
