Smoke Density Vertical Flammability Test For Building Material Decomposition

Smoke Density Vertical Flammability Test For Building Material Decomposition

Scope of application:

The test machine for decomposition of the smoke density of building materials is applicable to the determination of the static smoke volume of building materials and their products when they are burned, and also can be used for the determination of the amount of static smoke produced during the combustion of other solid materials.

Meet the standard:

Compliance with GB/t8627-2006 standard test requirements for smoke density test methods for building materials.

Main features:

Equipment structure:

The machine consists of a combustion box, a computer control system and two parts.

Size of combustion box: L300*W300*H790(mm);

The combustion box adopts high quality baking paint, CNC machine tool processing and forming, the arc shape is beautiful and large;

The internal parts are made of 304 stainless steel materials, and the rust resistance is excellent.

Conditions of use:

Ground level, good ventilation, free of inflammable, explosive, corrosive gas and dust.

There is no strong electromagnetic radiation source nearby.

Proper maintenance space surrounds the equipment.

Temperature: 25 ℃ ~ 35 ℃.

Power supply: AC220V/ 50HZ.

Voltage allowable fluctuation range: 220V plus or minus 10%.

Frequency allowable fluctuation range: 50Hz plus or minus 1%.

The user is required to configure the air or power switch of the corresponding capacity at the installation site, and the switch must be exclusively for use by the equipment.

Main parameters:

Gas source: 95% propane gas, or equivalent gas (customer's own);

Combustion lamp: for the original lamp, length 260mm, nozzle diameter 0. 13 mm, and the smoke box into a 45 ° Angle;

Photoelectric system: the light source is the filament - intensive meter lamp, working voltage 5. 8 v.

Exhaust air system: this machine has powerful exhaust fan. After the test, the exhaust can be discharged out of the air.

Smoke density measurement range: 0~ 100%;

Measurement accuracy of smoke density: plus or minus 3%;

Receiver: for the silicon photocell, the transmittance of the light is 0%. The transmittance of the light is 100%.

After processing the focal length: a focal length for the (60 ~ 65) mm lens will beams converged on the instrument right arm of the photocell, light source is installed in the smoke box left arm out to a light source box, located at the base of 480 mm high above the place;

Main burner work pressure: 276KPa (adjustable, note: 1Mpa=10kg/cm2= 1000Kpa);

Auxiliary burner pressure: 138KPa (adjustable, note: 1Mpa=10kg/cm2= 1000Kpa);

Automatic timing, automatic smoke exhaust; The luminous flux can be automatically corrected;

Computer control, a set of transmittance measurement software, output curve report, automatic data saving and printer;

Calibration of light transmittance: using different filters to calibrate the light source online, the average value of the display value and the calibration value of the filter is < 3%;

Data processing: computer automatic recording three parallel test, smoke density measured by every 15 s average value obtained, and the value against the smoke density and the test time of integral curve, and print out the test report;

Calibration filter specification: 25%, 50%, 75% of a set of three, according to standard gb8627-2007 7. Section 14 configuration.
