Description

Combustion test device

The present invention relates to a combustion test apparatus, in particular, all heating time when the autoignition switch is turned on after fixing a sample (eg plywood, synthetic resin, curtain, carpet, rope, etc.) to be tested for flame retardant performance. Excessive flame retardation and residual time are precisely measured (e.g .: up to 0.1 seconds), and then displayed digitally to make it easier to see the results of the performance verification on the sample. The present invention relates to a combustion test apparatus that opens and closes a door of an apparatus to remove gas remaining therein by a separate combustion operation to prevent a safety accident after a flameproof test.

As is well known, the combustion test apparatus is not shown, but composed of a combustion test apparatus box, a test tube supporter, an electric flame generator, a McKell burner, a microburner, and an air mix burner, and then a sample to be tested in the test receiver supporter. Put it on and ignite it to generate a spark.

And the flame resistance to a sample is measured by applying the said flame to a sample for a predetermined time.

However, the conventional combustion test apparatus as described above has not been able to calculate the accurate flame retardant performance on the sample because the performance measurement in the analog method.

In other words, when the flame generated from ignition burns a sample, the flameproof performance measurement of the sample according to the burning state is displayed in an analog manner, and this should be checked by the operator. It is a disadvantage that the flame retardant experiment is not performed properly.

In addition, since the combustion test apparatus cannot open the door of the combustion chamber for a predetermined time in a state where the flame test is completed on the sample, it is very difficult to remove the predetermined gas remaining inside the flame test after the flame test.

That is, the conventional combustion test apparatus does not have a function of removing the residual gas remaining inside after the flameproof test. In the next flame test, there was a big safety problem that caused an accident from the remaining gas.

Thus, in the related art, the door of the combustion test apparatus is often opened to remove the gas remaining in the combustion test apparatus, but at this time, the leakage of the remaining gas occurs, which affects the tester.

Therefore, the present invention was devised to solve the conventional problems as described above, the object of the present invention, after fixing a sample (eg plywood, synthetic resin, curtains, carpets, ropes, etc.) to test the flame retardant performance to the test body When the auto ignition switch is turned on, all heating time, afterflaming time, and remaining time are precisely measured (e.g.: up to 0.1 second), and then displayed as digital, so that the result of the performance verification on the sample can be more easily understood. In addition, to provide a combustion test device that can prevent the safety accidents after the flame test by opening the door of the combustion test apparatus and removing the remaining gas in the combustion test apparatus in a separate combustion operation after the flame test is completed. will be.

That is, when complex salts occur in the sample that has been burned, the heating time of the heating time meter 41 is first set again (for example, 30 seconds) as well as the heating time meter 44 after complexing through the up / down switch 4. ), The heating time after complexing (eg 3 seconds) is set.

Subsequently, when the ignition button unit 300 and the heating button 35 are sequentially operated in a state in which a new sample of the same type is placed on the sample holder 1a, the air-mixer is operated from the operation of the heating button 35. In 2), the ball flower is applied to the sample placed on the sample holder 1a.

In addition, when the post-dyling heating button 34 located on the panel 100b of the combustion test apparatus 100 is pressed, the system control unit 70 according to the pressing operation of the post-decomposition heating button 34 heats up post-dyling heating time. After supplying the gas to the airmixer 2 for the time set in the system 44, the switch SW2 is turned off to stop the gas supply to the airmixer 2, and thus the air mixer is stopped in accordance with the gas supply interruption. The flame in the burner 2 disappears.

At this time, while stopping the heating of the air-mixer (2) at the same time it is placed on the sample support (1a) while determining whether the residual salt is present in the heated sample for a predetermined time to measure the performance of the sample according to the determination result Will be.
