Scope of application:

The steel structure fire retardant coating sample test furnace is suitable for the fire resistance test of all kinds of steel structure fire retardant coating small samples used inside and outside the building, and is not suitable for the sample with a length greater than 800cm.
operating interface and development software LabView, the interface style is fresh, beautiful and simple. During the test, the measurement results are displayed in real time and the perfect curve is dynamically drawn. The data can be permanently saved, accessed and printed out, and the report can be printed directly. It has the characteristics of high intelligence, guided menu operation, simple and intuitive, which makes the test results more accurate.

Standard:

GB/T9978.1-2008 "Building components fire resistance test method Part 1: General requirements" Chapter and Chapter 6 requirements, GB/T14907-2018 "Fire retardant Coatings for Steel Structures" test standard, GBJ17-2003 "Code for Design of Steel Structures" standard requirements, GA_T714-2007, GB/ T9779-1988 laminated architectural coatings.

Technical Parameter:
1.Equipment composition: Fire resistance test horizontal furnace, combustion control section, gas section and pressure reduction system, pressure release and measurement system, flue gas emission system, sample test stand, gas flow system, temperature measurement system (furnace temperature data acquisition system, test component temperature acquisition system), exhaust valve system, and dedicated test software.Using a 16 bit high-precision data acquisition module, various data such as temperature, pressure, flow rate, etc. are collected from various channels. Real time reproduction of the true information during combustion is generated through microcomputer analysis, processing, and control, and the results are directly obtained through microcomputer analysis and judgment. The whole machine adopts high-quality components to ensure the high quality, high-speed operation and progressiveness of the system.

2.Furnace structure: adopts a four layer structure, with the inner layer at 1300 ℃ and the outer layer at room temperature. From the outside to the inside, they are: the first layer is a stainless steel shell, and the second layer is a steel structure frame; The third layer is built with high-temperature bricks to form the periphery; The fourth layer is high-temperature ceramic cotton that can withstand temperatures up to 1700 ℃.

3.Burner:Two sets of high-pressure burners with a power of 60-80kw are used, which have air-fuel ratio control and closed-loop control formed by temperature feedback inside the furnace. The gas valve and air valve can be automatically adjusted to achieve the best combustion effect. To ensure safety, the burner selection and components are all from well-known brands.

4.Temperature measurement system:

Furnace thermocouple: The furnace adopts a wire diameter of 2.0mm that meets the requirements of 5.5.1.1 in GB/T9978.1 and GB/T 16839.1 Four K-type nickel chromium nickel silicon thermocouples, with heat-resistant stainless steel sleeves on the outer cover, heat-resistant materials filled in the middle, and stainless steel tube sleeves made of rigid material Jade tube sheath, with a length of no less than 25mm extending from the hot end of the sheath, and a temperature resistance of 1250 ℃ or above.

Back fire surface temperature measurement:There are 8 thermocouples on the back of the sample, of which 4 are copper plate thermocouples (welded with 0.5mm wire diameter thermocouples on the thick side)On a round copper sheet with a diameter of 12mm and a diameter of 0.2mm, it meets the requirements of the K-type nickel chromium nickel silicon thermocouple specified in the standard GB/T 16839.1,Each copper sheet is equipped with a 30 * 30 * 2 (± 0.5) mm asbestos insulation pad with a density of 900kg/m3 ± 100 kg/m3.The thermal coefficient is 0.117-0.143W/(m.k), which meets the requirements of 5.5.1.2 in GB/T9978.1. In addition, the outer diameter of the other 4 positions is 1mm.High precision K-type thermocouple, which can be buried on the back of the sample for insulation efficiency testing;

Mobile test temperature: meets the requirements of GB/T9978.1-2008; One handheld infrared measuring instrument is used to measure the surface temperature of each point on the backfire surface. Furnace temperature collection: K-type armored thermocouple is selected. High temperature resistance above 1250 ℃; The furnace temperature data acquisition system has real-time curve and historical curve storage functions, as well as thermocouple open circuit and short circuit alarm functions. Environmental temperature measurement: The equipment is equipped with a stainless steel armored thermocouple with an outer diameter of 3MM for testing.Verify the ambient temperature and comply with the K-type nickel chromium nickel silicon thermocouple specified in GB/T 16839.1.

5. Pressure measurement system: Furnace pressure measurement: measurement range 0-100Pa; We use a French imported differential pressure gauge, which is a T-shaped measuring probe with a measurement accuracy of ± 0.5Pa. Equipped with overpressure protection function, when the furnace pressure exceeds 100Pa, execute program overpressure protection, stop gas supply, and terminate the test; Compliant with GB/T9978.1-2008 standard; The pressure inside the furnace is recorded every 1 minute, and the accuracy of the recording equipment is 1 second. The data collection rate is 3 times per second. Furnace pressure control and data acquisition, ensuring real-time control of furnace pressure in accordance with the requirements of various standards in Chapter 2 and the smoke exhaust system control circuit.

T-shaped measuring probe: Using SUS310S high-temperature resistant stainless steel tube, it passes through the furnace wall from inside the furnace to outside the furnace, and the pressure inside and outside the furnace is maintained at the same level. Pressure transmitter: French Kaimao high-precision pressure sensor. Within 5 minutes of the start of the experiment, it is 15Pa ± 5Pa, and after 10 minutes, it is 17Pa ± 3Pa.

6. Pressure relief system: 6.1 There are smoke exhaust holes installed on the rear side of the furnace wall, connected to the smoke exhaust pipe, to control the pressure inside the furnace by discharging the smoke inside the furnace. The air supply and exhaust inside the furnace are controlled by a 0.3kw powerful fan and a frequency converter, and the air volume is automatically controlled by a computer program to meet the requirements of combustion, pressure, and smoke exhaust; 6.2 Pressure release pipeline: The section inside the furnace is made of high-temperature resistant SUS310S stainless steel pipes with a diameter of 300mm, capable of withstanding temperatures up to 1300 ℃. Use welded pipes with a wall thickness of 5mm outside the furnace; 6.3 Pressure release power: AC220, 0.3kw high temperature resistant high-pressure fan; 6.4 Furnace pressure control and data acquisition, the furnace pressure can ensure real-time control by forming a control loop with the smoke exhaust system according to the requirements of the above standards.
