Introduction: The fire-retardant wood test device (fire tube method) is suitable for testing the burning quality loss rate and the flaming burning time of interior decoration wood and wood products (d ≤ 20 mm) treated by flame retardant impregnation under the specified combustion conditions. Standards compliant GA/T 42.2 Technical Parameters: The test equipment consists of a fire tube device, an electronic balance, and a control box. 1, fire tube device The fire tube is made of a stainless steel plate with a thickness of 1 mm and a metal mesh. The total height of the fire tube is 1 257mm, the inner diameter of the upper mouth is 76mm, the inner diameter of the lower mouth is 152mm, and there are 25 air holes of ø9.5mm on the side of the fire tube. The distance between two adjacent air holes is 38mm. 1.1. There is an observation window on the tapered surface of the metal mesh. The observation window is a trapezoidal window with an upper side of 27mm, a lower side of 48mm and a height of 39mm. 1.2. There is a ø48mm circular test piece retaining ring in the fire tube, and the fixing ring is made of ø3.2mm steel wire. 1.3. The entire fire tube is placed on top of the electronic balance. 2. Electronic balance The weighing range is 0~6 000g, which is accurate to 0.1g. 3, PLC + 5.7-inch touch screen control, can achieve automatic ignition, set the flame time, collect and store data and other functions 4. Burner Low-profile copper curved tubular blowtorch with inner diameter of 9.5mm, stable flame combustion 5, imported Japanese Omega rotor flowmeter, flow range 0-10L / min 6, gas: liquefied petroleum gas 7. Thermocouple: K-type armored thermocouple with precision class II and outer diameter of 3 mm, temperature detection range RT-1050°C
