Stainless Steel Flame Spread Ability Tester For Films And Textiles 220V 30A

Stainless Steel Flame Spread Ability Tester For Films And Textiles 220V 30A

Product introduction

The flame spread tester is used to determine the lateral flame spread performance of building products. The flame spread performance/flame spread speed can evaluate the fire retardant performance of materials.

The device measures the combustion of a material at a given radiant heat level by radiating heat through a gas-fired radiation panel and using an imported heat flow meter to calibrate the radiant heat and ignite the specimen through a mixed gas burner; the sample is exposed to a clearly defined radiant flux area and the ignition time, flame spread and final extinguishing time are measured. The test sample is placed in a vertical position, close to the radiation panel, and exposed to a clearly defined area of radiation flux. After ignition of the flame close to the test sample, but not in contact with it, the development of the flame front is recorded and the time taken for the flame front to burn horizontally on the surface of the sample to reach each calibrated distance is recorded. In turn, the material is tested for heat of ignition, heat of continuous combustion, critical flow rate, average heat of continuous combustion, total heat release and other related parameters.

Features

1. The box is made of stainless steel, beautiful and corrosion-resistant; easy to clean; main frame: it consists of two independent parts: the burner frame and the specimen support frame. The two parts are connected by bolts, and there are bolts for flexible mechanical adjustment.

2. Ignition source: radiation plate and propane torch imported from USA. Precise control of flame height

3 . Burner, (200±10) mm long double-hole ceramic tube.

4 . Cylinder type ignition burner supports IMO standard automatic flame impact test

5 . Double grill and enlarged lens for user to observe the flame spread

6. Radiation plate temperature controller: prevent the flame from turning to the back side of the heat sink, check the internal temperature of the heat sink, and prevent the flame from spreading in the flame.

7 . Flow controller can easily test the methane content when testing the critical heat flow of the gas

8 . Gas supply: equipped with pressure reducing valve, zero pressure valve, tempering valve, solenoid valve and mixer to deliver the mixed air and gas to the radiation plate.

9. Provide multi-hole calibration plate, and sliding heat flow meter moving track, can detect whether the heat radiation flux meets the standard requirements

10 . Equipped with angle adjustable observation mirror (750mm×120mm), the test can be observed through the glass mirror and specimen rake, the flame spread rate, and can be automatically recorded through the foot switch.

11. specimen chimney, 1, equipped with gas and chimney metal compensation thermocouple.

12 . All radiation plate combustion control system in the safety of explosion-proof, non-return valve, gas break solenoid valve can prevent gas backflow

13 . Camera to observe and save the test process condition in a program

14 . Measurement of the heat flow state of the radiation plate within a 50 mm interval

15 . Data acquisition system can store images of flame spread length and combustion characteristics

16 .19" analysis frame to measure flame spread rate, critical flow rate, heat release rate

17. Radiant plate burner system is fully automated with spark ignition and safety lock; all control systems are explosion-proof
