Introduction>AtLTextile Testing Instruments, Testing Equipment Manufacturer
The test instrument is used to detect the flame resistance of the blanket fabric and the flame spread performance of the fabric surface. The test method is to burn the surface of the specimen with a standardized flame for a specified period of time. Thus, the burning, damage degree and color change of standard test paper are observed and then assess the test fabric grade.AtLTextile Testing Instruments, Testing Equipment Manufacturer

Structure>AtLTextile Testing Instruments, Testing Equipment Manufacturer
Flowmeter :Adjust the gas flow size.AtLTextile Testing Instruments, Testing Equipment Manufacturer
Fire tube : The gas is first connected to the flow meter through the hose, and then through the rear hose of the box into the flame pipeAtLTextile Testing Instruments, Testing Equipment Manufacturer
Windscreen: the upper part of the windshield is provided with glassAtLTextile Testing Instruments, Testing Equipment Manufacturer
The experiment was carried out in a ventilated kitchen. The round hole on the top of the box and the gap on the windshield make the gas convection.AtLTextile Testing Instruments, Testing Equipment Manufacturer
Control panel :Power- power switch ;Start:Start internal motor operation. When the flame tube moves to the test position (the vertical distance from the sample center is 8mm, the horizontal distance is 3.2mm), the internal timing switch is touched;AtLTextile Testing Instruments, Testing Equipment Manufacturer
Reset :Timer reset /Fire tube reset.AtLTextile Testing Instruments, Testing Equipment Manufacturer
Sample clamp and specimen holder :The sample frame substrate is provided with a knob which can adjust the left and right movement, and the sample frame substrate is moved and fixed by loosening and tightening the knob.AtLTextile Testing Instruments, Testing Equipment Manufacturer
Timer :Display settings and actual ignition time.After the time is cleared, the fire tube can complete the required movement. Or the fire tube can not return to the original position after moving forward.AtLTextile Testing Instruments, Testing Equipment Manufacturer

Operation>AtLTextile Testing Instruments, Testing Equipment Manufacturer
● After the sample is ready and the instrument is commissioned, place the assembled sample clamp on the specimen holder.AtLTextile Testing Instruments, Testing Equipment Manufacturer
● Open the gas valve and supply the gas to the fire pipe. Use the electronic igniter to fire the burnerAtLTextile Testing Instruments, Testing Equipment Manufacturer
● Press the start button on the control panel. The fire tube moves forward and moved to the test position under the action of the mechanical transmission. Then, Start the ignition of the sample and test paper on the sample holderAtLTextile Testing Instruments, Testing Equipment Manufacturer
● At the same time to start the ignition timing system, the control panel display and record the ignition time. After a second, the fire tube moving backwards, the timer stop time. The experiment is end.AtLTextile Testing Instruments, Testing Equipment Manufacturer
● Finally remove the sample and test paper for rating.AtLTextile Testing Instruments, Testing Equipment Manufacturer
