KP8033 display oxygen index apparatus
1. Standard:
Conform to GB/T2406 "plastic combustion performance test methods - oxygen index method and JIS7201, BS2782, ANSI/ASTM, D2863, ISO4589, test standards.
2. The scope of application:
Used to judge the material in contact with the flame in the air when it is the ease of burning, is applicable to homogeneous solid materials, laminated materials, film and thin film materials.
3. The main parameters:
3.1 oxygen concentration (oxygen index) : in order to display direct reading
3.2 (oxygen index) of oxygen sensor: American imports.
3.3 three gauges provide oxygen respectively output pressure, nitrogen output pressure and mixed gas output pressure, size can be adjusted through the control valve pressure.
3.4 measuring range: 0-80%, resolution: 0.1 L/min
3.5 accuracy: 2.5 on the Richter scale are unlikely
3.6 combustion tube, quartz glass tube, the inner diameter: 100 mm height: 500 mm
3.7 combustion tube at the top of the gas flow rate: 90 mm - 10 mm/s
3.8 combustion gas inside the cylinder velocity: 40 mm + / - 2 mm/s
3.9 input pressure: 0.25 ~ 0.5 Mpa is adjustable;
Oxygen, nitrogen mixture gas entrance 3.10: including voltage regulator valve, flow regulating valve, gas filters and mixing chamber.
3.11 the sample holder can be used for soft and hard plastic.
3.12 igniter: dedicated butane handheld electronic electric firearms
3.13 gas: industrial oxygen, nitrogen.
3.14 timer accuracy: + / - 0.5 s
3.15 the power requirement: AC220 (+ / - 10%) V / 50 hz.
4. The case and part of the structure:
Control box: the numerical control machine processing molding, circular modelling beautiful generous. High quality SUS304 mirror stainless steel material, beautiful, rust corrosion.
Combustion tube, high temperature resistant high quality glass tube (￠inner diameter 100 mm, 100 mm) long
Outlet inner diameter: phi is 40 mm
Mixer: USES the glass bead filled form, oxygen and nitrogen gas mixing. (4.5 mm bead phi fill height 95 mm)
Sample clamp: self supporting jig, and vertical clamp samples.
5. Electrical control system:
The relay control system, all have electronic originals adopt domestic leading brand, can better guarantee the performance of the machine and testing accuracy.
Equipment has the following safety protection device: power overload, short circuit protection, overload protection of control circuit.
