1. Scope of application:
automatic comprehensive calorimeter, used to determine the thermal
calorific value of fireproof building materials, the results are
used to determine the fire rating of materials, so as to evaluate
the fire performance of materials, the measured results meet the
requirements of the national standard GB/T14402-2007 "combustion
performance of building materials and products - determination of
combustion calorific value", in the constant heat capacity of the
oxygen bomb calorimeter, the test of measuring the combustion
calorific value of building materials. This includes the total
calorific value and net calorific value of combustion.
Automatic comprehensive calorimeter is also used to measure the
calorific index of solid combustibles such as coal, coke, gangue,
etc., to measure the quality of the measured object. It is widely
used in electric power, coal, metallurgy, petrochemical, quality
inspection, environmental protection and other industries. The
measured results meet the requirements of the national standard
GB/T213-2003 "Methods for Determining the Calorific Value of Coal".
It is also the main instrument of the coal laboratory.
2. Performance characteristics:
1. Embedded high-precision data acquisition and computer system are
used to control the instrument to realize automatic water filling,
automatic water temperature adjustment, automatic water
quantification, automatic stirring, and automatic ignition.
2. It has all the functions of intelligent calorimeter, high test
accuracy, stable performance, low failure rate, system constants
and experimental results can be stored for a long time and are not
lost after shutdown, etc., and have the advantages of high cost
performance.
3. Using microcomputer control, equipped with professional testing
software, compatible with windowsXP and windows7 operating systems,
friendly software operation interface, users only need to install
aerobic bombs to complete the whole experimental process.
Intuitive, friendly, easy to learn, and easy to use. Equipped with
a serial printer, the experimental results are clear at a glance.
4. This equipment has the characteristics of simple test and
complete functions, which can not only test the thermal calorific
value of fireproof building materials, but also determine the
calorific value of solid combustibles such as coal, coke, gangue,
etc., and meet the two standards of GB/T14402-2007 and GB/T213-2003
at the same time, so as to realize the multi-purpose of one
machine.
3. Executive standard:
in line with GB/T14402-2007 "Combustion Performance of Building
Materials and Products - Determination of Combustion Calorific
Value", ISO1716-2002 "Fire Reaction Test of Building Products -
Determination of Combustion Calorific Value" and GB/T213-2003
