Igniter 25 position is in the downside at instrument back, for the igniting of igniter plug 20；Described control system includes that this display screen 11 is driven by mainboard 9, and for controlling and the main frame of computing, described main frame is provided for external USB interface 4 for showing information or the display screen 11 of input information；Barometric pressure sensor 12, flame sensing transducer 7, PID regulating block 3, solid-state relay 8, temperature signal isolating transmitter 5, serial ports relay circuit plate 1 and probe chip 17, induction heat galvanic couple 19 and igniter 25 connect described main frame, and are controlled.Barometric pressure sensor 12 is for detecting the air pressure situation in experimental enviroment；Flame sensing transducer 7, for the temperature of flame is converted into the level signal of height change, is input in central processing unit, and central processing unit makes corresponding process according to the change of signal；Temperature signal isolating transmitter 5 is for being the readable signals of electronic devices and components by daily temperature inversion；PID regulating block 3 is used for regulating temperature and carries out thermostatic control.
Described chassis 3 lower end is provided with shockproof footing 2, and described shockproof footing is provided with 4, is used for supporting chassis.
Next sample cell 22 is placed on test platform, the syringe pin hole of injection mechanism is the most vertically placed in retaining collar, test(ing) liquid with syringe extraction more than 6mL (most 7mL), then magnetic clip is buckled, carrying out 3 efficiency tests for a temperature spot, concrete process of the test is as follows:
The first step: during start, confirm that current application program is opened, click on " entrance system " and jump to main interface, main interface is clicked on " starting test ", entering test interface, the left-hand component at test interface is filled in operator, substances, test number, is preset the fundamental test parameters such as test temperature, heat time, sample size.
Second step: test preparation and parameter are after setting completed, click on " starting test " button at test interface, eject " experiment porch whether level " dialog box, platform whether level is judged by the level meter on test platform, " determination " button is clicked on after determining level, in thermostatic control stage on-test, " test temperature-time " curve in the middle of test interface starts to draw, and this curve is accumulation curve.
3rd step: when temperature reaches to preset test temperature, spark plug starts igniting, can regulate flame size by pressure maintaining valve, after probe distal end detects flame, " please placing sample in syringe, click on and determine after placement " dialog box is ejected in test on interface, and buzzer can pipe the time of 2 ~ 3 seconds, alarm lamp is bright, clicking on " determination " after placement, start injection test and penetrate 1mL, injection mechanism is automatically moved at test platform, start injected sample, return to after injection in situ.
4th step: the details of the right display test progress at test interface, just carrying out the stage of the text box meeting output test under test progress word；The following information of text box is heating timing, flaming combustion time shows, test flame ignition, sample is lighted, sample sustained combustion etc..When some phenomenon occurs, such as, test flame ignition, then corresponding indicator lamp by grey virescence, when heated between reach 60s after, this test terminates automatically, and " test flame ignition " indicator lamp is the most dimmed.
5th step: after test specimen burning terminates, click on " lower one page " and enter data process interface, it can be seen that when time test data of record: as whether lighted a fire when content of the test, number of times, test flame are in off position and the information such as fired state, and correlation test result, by clicking on " derivation form " button, generate when time experimental report is Excel form, during preservation, note renaming, click on " checking form " and current result of the test can be checked.
Note: at the end of test carries out 3 times, eject " test has concluded that sample sustained combustion " prompting frame, click on " determination ", click on " lower one page " and enter data process interface, test data display interface will show the result of the test of 3 times, and show result of the test on the right side at interface: sample sustained combustion；Click on " derivation form " and " checking form " can result of the test be checked.When temperature control in process of the test, buzzer can persistently pipe, and alarm lamp is bright, until instrument adjusts temperature automatically to critical field.
nullThe incombustible process of the test of sample: when temperature reaches to preset test temperature，Spark plug starts igniting，After probe distal end detects flame，" test flame ignition " indicator lamp brightens，Test is ejected on interface and " is please placed sample in syringe，Click on after placement and determine " dialog box，Now carry out setting-out，" determination " is clicked on after placement，Start injection test and penetrate 1mL，Injection mechanism is automatically moved at test platform，Start injected sample，Return to after injection in situ and heating chronometric data starts change，After burning timing reaches 60s，It is not detected by flame，Flame-thrower nozzle moves near sample cell，Reheat 15s，Timing is started at heating timing，Flame still it is not detected by after 15s，" test flame ignition " indicator lamp is dimmed，Off-test，Click on " lower one page " and enter data process interface，It can be seen that when time test data of record，Result of the test display "No".
If not observing sustained combustion at test temperature 60.5 DEG C, then repeat whole program with new sample at test temperature 75 DEG C.
If a kind of situation should say it is sustained combustion below the generation that any one sample is in two heat times or two test temperatures:
A () test flame is when off position, sample is lighted and sustained combustion；
(b) test flame testing position stop 15 seconds time, sample light and test flame return to off position after sustained combustion more than 15 seconds.
The spark of interval should not be construed as sustained combustion.Generally at 15 seconds then, burning or stop the most significantly or continue, material should be regarded as sustained combustion.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be regarded as in scope.
