Solid Material Textile Testing Instruments , 170Kpa Smoke Density Meter
Scope of application:
This instrument is suitable for all solid materials, also can be applied to other materials of assessment (such as rubber, textiles, covers, paint, wood and other materials), by solid materials industry production factories and research of the unit is widely used.
Solid material smoke density meter is based on Standard "solid materials to produce than the optical density of smoke test method" and "Standard test method for specificoptical density of smoke generated by solid materials" in the technical conditions stipulated in the development of a new type of solid material was developed for the determination of smoke density test equipment, the standards applicable to the determination of smoke produced during the combustion of solid materials than light density, and the biggest than light density of the test results. It is used to evaluate the smoke performance of plastic under specified conditions.
Meet the standard:
In conformity with GB/t10671-2008, the test method for the density of smoke in solid materials and ASTM E 662: Standard test method for specificoptical density of smoke generated by solid materials in 2006.
Main parameters:
Heating system:
1. Radiant furnace: controlled by the thyristor voltage regulator, constant thermal radiation is produced on the sample surface during the test, so that the average radiance of the sample surface reaches 2.5 W/cm2.
2, the burner: all of the six standard burner nozzle and specimen exposed surface into a 45 ° Angle 0 ° 90 °, respectively, 90 ° nozzle on both sides, 45 ° nozzle in the center.
3. Heat flow meter: the range is 50kw/m2, and the area of flat area with radiation area of 10mm in diameter is coated with matte black, which is cooled by water cooling.
4, ignition, ignition nozzle is made from Φ 4.0 mm diameter copper tube, the flame length, horizontal measurement of 30 mm.
Air supply system:
5. Air source: the purity is 95%, propane and air mixed gas, pressure is 170Kpa
6. Propane flow meter: 1~100cm3/min
7. Air flow meter: 5~500cm3/min
Machine performance:
1. Transmittance resolution: 0.0001%;
2. Measuring range: 0-100%; Automatic shift in measurement.
3. Measurement accuracy: plus or minus 3%;
4. Working voltage: ac200-240v 50Hz;
5, environmental humidity: room temperature - 40 ℃
6. Working environment: when the instrument is running, it should avoid strong light direct shooting and no forced air flow.
