Oxidation induction period analyzer operation steps

Oxidation Induction Time (OIT) is a measure of the time at which an autocatalytic oxidation reaction begins to occur at high temperature (200 ° C) oxygen. It is an indicator of the thermal degradation resistance of a material during molding, storage, soldering, and use. The Oxidation Induction Period (OIT) method is a method for testing the accelerated ageing of plastics in high temperature oxygen using differential thermal analysis (DTA) based on the exothermic reflection of plastic molecular chain breaks. The principle is to place a plastic sample and an inert reference material (such as alumina) in a differential thermal analyzer to rapidly replace the inert gas (such as nitrogen) in the sample chamber with oxygen at a certain temperature. The change in the DTA curve (differential thermal spectrum) due to the oxidation of the pattern was tested, and the oxidation induction period (time) OIT (min) was obtained to evaluate the heat aging resistance of the plastic.

1. First open the purge gas, and the gas flow rate is controlled at about 120ml/min. The atmosphere is generally selected from inert gases such as nitrogen, helium, and argon, and some samples may be used in an air atmosphere.

2. Turn on the computer, connect the instrument data cable to the computer, plug in the instrument power, and turn on the switch on the back of the instrument.
3. Open the software and measure at the oxidation induction interface.
4. In the menu bar [Settings] option, select [Parameter Setting], the dialog box shown in Figure 2 appears, the cut-off temperature is 200 °C, the heating rate is 20 °C / min, and the constant temperature time is 200min. Click "Settings" to exit.
5, the appropriate amount of sample, usually 10 ~ 20mg, placed in the sputum
6. Open the DSC furnace body (guaranteed to room temperature), place the crucible containing the sample on the sample tray in the furnace body with tweezers, and take another identical space on the reference tray for reference. Cover the furnace cover
