DX8810A Steel Structure Fireproof Coating Sample Test Furnace

1.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. With WINDOWS 7 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.

2.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.

3.Technical Parameter:
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.

4.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.
