The invention provides a liftable oxygen index tester. A PLC controller and an adjustment device are mounted in a box body; the PLC controller is connected with an operation panel; the operation panel is mounted on the outer surface of the box body; the liftable oxygen index tester also comprises an oxygen tank, a nitrogen tank and a fuel gas tank; the vent pipes of the oxygen tank and nitrogen tank are combined into a mixed pipeline through a Venturi mixer; the mixed pipeline is connected with a gas nozzle; the gas nozzle is mounted at the bottom of a gas flow disturbing device; a gas outlet is formed at the top of the gas flow disturbing device; a gas leakage chamber is mounted above the gas flow disturbing device; a glass cover is mounted outside the gas leakage chamber. In the liftable oxygen index tester provided by the invention, comprehensive mechanization and intelligentization are realized, various performance data and experiment parameters can be controlled and checked through the operation panel, and the test need for the combustion performance of various polymer materials can be met.
Description
technical field [0001] The invention belongs to the field of combustion performance testing, in particular to an adjustable oxygen index tester. Background technique [0002] The oxygen index tester is used to evaluate the combustion performance of polymers under specified test conditions, that is, to measure the minimum volume percentage concentration of oxygen that the polymer just maintains combustion. When a substance burns, it needs to consume a large amount of oxygen. Different combustibles require different amounts of oxygen to be consumed during combustion. By measuring the minimum amount of oxygen consumed during the combustion of a substance, the oxygen index value of the substance is calculated to evaluate the combustion of the substance. performance. The instrument is suitable for the combustion performance test of plastic, rubber, fiber, foam plastic and various solids, with good accuracy and repeatability, so it is widely used by countries all over the world. ...
