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.
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.
