In line with JIS7201 standard model is DX8355 digital oxygen index detector

1. Meet the standard: GB / T2406 "Test method for flammability of plastic --- oxygen index" standard; meet JIS7201, BS2782, ANSI / ASTM, D2863, ISO4589, GB / T2406 standard. 2. Scope: For ease of judging material in contact with the flame in the air for a homogeneous solid materials, laminates, films and film materials. 3. The main parameters: oxygen concentration (oxygen index) oxygen concentration (oxygen index) Sensor: US imports Analog pressure of oxygen, nitrogen pressure, through a valve to adjust the size. Measuring range: 0-80%, resolution: 0.1L / min Accuracy: 2.5 combustion tube diameter: 75 mm cylinder combustion gas flow rate: 40mm ± 10mm / s Working pressure: 0.1Mpa oxygen, nitrogen mixed gas inlet include: regulator valve, flow control valves, gas filter and the mixing chamber. Sample holder that can be used in soft and hard plastic. Ignition: Special butane gas handheld electronic electricity Firearms: industrial grade oxygen, nitrogen. Power requirements: AC220 (± 10%) V / 50HZ. The chassis and the partial structure: control box: The CNC machining, circular shape nice quality SUS304 mirror stainless steel material, beautiful, rust and corrosion. Combustion tube: high temperature glass tube (inner diameter ￠ 100mm, length 450mm) exit inner diameter: φ40mm mixer: the use of glass beads filled in the form, the oxygen and nitrogen uniformly mixed. (Pearl φ4.5mm filling height 95mm) specimen holder: self-supporting jig, and can vertically across the sample. 5. The electric control system: relay control system, all electronic components are used in leading brands, to better ensure the performance and detection accuracy of the machine. Devices have the following safety devices: power overload, short circuit protection, overload control loop. Test methods for flammability of plastics - plastic oxygen index in the air by an external heat source or sources of ignition heating degradation, resulting in volatile products, flammable products and energy products, in the continuing role of the external heat source, it can reach a certain temperature combustion, part of the heat released by burning through conduction, radiation and convection other ways, by being degradable plastic absorb more volatile flammable products; combustion process exacerbated the flames surrounding air turbulence, increasing the flammability of volatiles and air The degree of mixing, the combustion is more intense. Biomass burning need to consume large amounts of oxygen, different fuel, different amount of oxygen consumed during combustion, by determining the minimum amount of oxygen consumed in the combustion process of the material, the oxygen index value is calculated to evaluate the substance of the combustion properties of the material. Oxygen index is under specified test conditions, the sample in oxygen and nitrogen mixed gas stream to maintain stable combustion (namely, flaming combustion) the required minimum oxygen concentration in the oxygen percentage share of volume (ie, the After the substance ignited during combustion to maintain oxygen 3min 50mm long, or need, a mixed gas of nitrogen concentration in the lowest percentage of oxygen by volume), it is a representation of the evaluation burning plastics and other polymer materials relative, as judged by material ease of contact with the flame burning in the air. Generally considered: oxygen index <27 is a flammable material, 27≤ oxygen index <32 genera of combustible material, oxygen index ≥32 is a flame retardant material. Oxygen index test method, is to sample a certain size folder with sample holder perpendicular to the transparent combustion cylinder, which has a certain proportion of oxygen by a mixture of upward mobility, nitrogen mixed gas stream. After igniting the upper end of the specimen was observed subsequent combustion phenomenon, records continued to burn time or burnt distance. Sample burns longer than 3min or flame marking the leading edge exceeds 50mm, reducing the oxygen concentration, the burning time is less than 3min sample or not marking the flame front, increasing oxygen concentration, so repeatedly, from upper and lower sides move closer to the provisions of value, to the concentration difference between the two is less than 0.5%. A set of test specimens in different oxygen concentrations, measured just maintain the minimum oxygen concentration plastic steady combustion, with the volume percentage of oxygen in the mixed gas expressed.
