Thermoplastic Heat Insulation Combustion Chamber , White Flame Test Apparatus

White Thermoplastic Material Flammability Testing Equipment With Heat Insulation Combustion Chamber

Scope of application:

Products are suitable for wall inner surface and the ceiling surface, especially for some reason (insulating substrate. Seams. The larger the effects of irregular surface), can in laboratory scale test of products, such as thermoplastic material.

Meet the standard:

Compliance with GB/t25207-2010 fire test method of physical room of fire test surface products;

Compliance with ISO 9705:1993 "fire test." standard requirements for laboratory test of indoor objects;

ISO9705:1993 Fire tests. Full scale room test for surface products.

Main parameters:

The whole machine consists of three parts: standard combustion chamber, large calorimeter and data acquisition and processing system.

1. Standard combustion chamber:

Inner dimensions: 2.4m wide x 2.2.4 m long x3.6m height

Structure: using masonry structure, indoor wall surface and top face are respectively attached with 15mm refractory glass second cotton. Built in a non-mechanical ventilation. Heat insulation and large enough room to ensure no impact on the lab.

The center of the north wall of the combustion chamber has a gate of 0.8m-wide x2m, and a 2m x2m viewing window on the east wall.

An electron is placed at the geometry center of the combustion chamber. The measuring range is 0--500 kg, and the measurement accuracy is 0.001kg, which can be used to measure the loss of the combustor during the combustion process.

2. The total fire

Southwest corner of the room set up total fire, firearms, the total fire use square openings of gas total firearms within the total is divided into two layers, the lower is the grit, the upper is fine sand, separated with wire mesh in the middle

Burner air source: more than 95% propane.

3. Measurement of heat flow in the test room:

Heat flow meter: range, 0--50kw/m2

Heat flow accuracy: plus or minus 3%

Reduplication error: less than 0.5%.

4. Smoke extraction system

Hood: sets at the bottom of the hood size is 3 m x3m, 0.1 m high. The bottom side to test room, the rest of the trilateral plate down 1.0 m. connected to the cross-sectional area of 0.9 long x0.9 wide x1m high mixing chamber, the mixing chamber set two 0.5 m x0.9 m partition.

Smoke exhaust pipe: connected with the mixing chamber, the inner diameter is 400mm, the straight pipe is 4.8m, and the two ends have 0.2m-long equalizer. The outlet is connected with the purification part (the purification is not included).

Smoke exhaust fan: the amount of smoke exhaust can be adjusted between 0.5kg- 4kg/s

Requirements of instruments in pipe line:

Volume flow: range, 0.1kg- 5kg/s

Measurement accuracy of volume flow: plus or minus 5%,

Volume flow response time: no more than 1s.

5. Gas analysis:

Oxygen: range 0-25%, measurement accuracy, plus or minus 0.05%, response time, 3s

Carbon monoxide range: 0-1%, measuring accuracy plus or minus 0.1%

Carbon dioxide range: 0-10% measurement accuracy, plus or minus 0.02%, response time: Angle 3s

6. Cigarette density:

Light source, halogen lamp 6v.10w

Lens: convex lens, 40mm in diameter, 50mm focal length

7. Temperature measurement:

Gas temperature measurement: 0.05m thermoelectric pot 7

Surface temperature measurement: 0.25mm thermoelectric pot 5
