The Textile Oxygen index tester is used to evaluate the combustion performance of polymers under specified test conditions, that is, to determine the volume percentage concentration of z low oxygen at which the polymer just maintains combustion.

 

1. Scope of application:

 

It is suitable for the determination of the combustion performance of plastics, rubber, fibers, foam plastics, flexible sheets and films, textiles and other materials.

 

2. Main technical parameters:

 

2.1. Using imported oxygen sensor, digital display of oxygen concentration does not need to be calculated, the accuracy is higher and more accurate, the range is 0-100 baifenhao

 

2.2. Digital resolution: ±0.1%

 

2.3. Display accuracy: 0.4 level

 

2.4. Flow adjustment range: 0-10L/min (60-600L/h)

2.5. Response time: <5S

 

2.6. Quartz glass cylinder: inner diameter ≥75mm high 480mm

 

2.7. Gas flow rate in the combustion tube: 40mm±10mm/s, the total height of the combustion tube is 450mm

 

2.8. The accuracy of the pressure gauge is level 2.5, resolution: 0.01MPa

 

2.9. Flow meter: 1-15L/min (60-900L/H) adjustable, test environment: ambient temperature: room temperature ~ 40℃; relative humidity: ≤70%;

 

2.10. Input pressure: 0.2-0.3MPa

 

2.11. Working pressure: Nitrogen 0.05-0.15Mpa Oxygen 0.05-0.15Mpa Oxygen/nitrogen mixed gas inlet: including pressure stabilizing valve, flow regulating valve, gas filter and mixing chamber.
