The testing principle of the flame retardant property tester is that the flame retardant property of the test sample is judged by recording the time (after-burning time) from ignition of the protective boot according to the specified requirements to flame extinction, checking whether each layer of material of the test sample has the phenomena of melting, dripping or obvious peeling and cracking separation and the like, and judging whether all hard accessories have good performance.
Wherein the recording of time is triggered by a proximity switch sensor disposed below the flame housing; when the flame cover is opened, the proximity switch sensor is triggered, the system starts to burn and time, when the time reaches 12s, the gas is automatically closed through the electromagnetic valve to extinguish the flame, the system stops burning and time and starts to time the 'afterflame time'; when the flame of the sample is extinguished, the experimenter presses a 'after flame stop' button to stop 'after flame time' to time and record the time in the touch screen.
Referring to fig. 1 and 7, the test procedure is as follows:
before starting up and debugging the instrument, the reliable connection of the power line and the sensor line of the instrument is required to be checked, whether the electrical component is normal (if obvious damage exists, the detection and the repair are required), whether the grounding of the instrument is reliable (the resistance of a column head from a shell non-insulator to a power socket is less than or equal to 1 omega), then the instrument is powered on, a power switch is turned on, and the starting up and the debugging are required to be carried out under the condition that the instrument is powered on
On a protective boot fixing seat for fixing the sample, a boot fixing handle is rotated anticlockwise to fix the sample (to ensure the reliable fixation of the sample);
loosening the rotary locking handle, rotating the protective boot fixing frame to enable the test sample to rotate to a corresponding test point, determining the height from the test point to the bunsen burner by using a randomly matched height column, recording the positions of the horizontal and vertical scales, moving away the bunsen burner, taking down the height column, vertically moving the test sample to the scales, and locking the rotary locking handle.
The Bunsen burner is removed, a gas outlet valve is opened, then a Bunsen burner adjusting valve is opened and ignited, the flame height is adjusted to 75mm, and random accessories, namely a flame height caliper gauge, can be used for confirmation.
After the flame is stably burnt, the flame housing covers the flame, and the bunsen burner is moved back to the test point position; then the flame housing is moved away to start the experiment, and the proximity switch sensor is sensed and timing is started when the flame housing is moved away; when the test is burnt for 12s, the system closes the gas through a gas solenoid valve on the gas inlet of the Bunsen burner, the flame is immediately extinguished and the afterflame time begins; the experimenter observes that the experiment stops when the flame of the protective boot is extinguished by pressing the 'continuous burning stop' button, and the system automatically records the 'continuous burning time'.
And continuing the experiment of other parts according to the steps two to four.
After the experiment is completed, whether each layer of the material of the sample has the phenomena of melting, dripping or obvious peeling and cracking separation and the like is checked, whether all the hard accessories have good performance, and finally, the test result is obtained.
