Rubber Oxygen Index Meterintroduction

The structure is simple and easy to operate, which can be used as a means of identifying the combustion performance of polymers, as well as a related research tool, thus obtaining a better understanding of the combustion process of polymers. It is applicable to the test of combustion performance of plastics, rubber, foam and other materials, with accurate results and good reproducibility. It is a testing instrument for researching and producing flame-retardant materials.

Rubber Oxygen Index MeterIt is an instrument that complies with the national standard GB/T2406.2-2009 and is used to determine the required oxygen concentration (volume percentage) during the combustion process of polymers. The polymer oxygen index value is the volume percentage of oxygen and nitrogen mixture gas with the lowest oxygen content required to maintain combustion for 50 millimeters or 3 minutes after ignition of the substance.
Rubber Oxygen Index Meterinstall

1. Unpack the instrument and place it flat on the workbench.

2. Connect the oxygen nitrogen mixed gas output end behind the control box to the pipe connector at the bottom of the host using the plastic reinforcement pipe in the random attachment, and tighten it with a pipe clamp. Attention: The nitrogen and oxygen inputs behind the control box correspond to the adjustment directions of the nitrogen and oxygen in front, respectively, and the mixed gas output end is in the middle (see Figure 1).

3. Install oxygen and nitrogen cylinders, and secure the pressure reducing valve on the cylinders. Connect the nitrogen and oxygen connectors on the rear panel of the control box to the output end of the pressure reducing valve of the oxygen and nitrogen gas cylinders respectively using the plastic reinforcement tube in the random attachment, and clamp them tightly with a pipe clamp. The steel cylinder and pressure reducing valve shall be provided by the user.

4. First, place the large hole diffuser ring column facing up and the small hole diffuser ring column facing down, and then install the combustion drum on the base (see Figure 2),

5. The method of filling glass beads and replacing fixtures is detailed in Figure 2

6. Igniter is an ignition device specifically selected for ignition, which can adjust the length of the flame. Users can inflate or replace the randomly carried igniter after the gas is exhausted (lighter uses gas).
