45 degree flammability chamber is designed to evaluate the flammability characteristics of fabrics. This instrument is applicable to evaluation of textiles such as clothing, furniture and drapery to name a few.
The 45 degree flammability test instrument has also been used to determine the flammability of paints and applied coatings under manufacturer specified procedures. Samples are placed into the chamber at a 45 degree incline.
A flame is introduced to the sample for a predetermined time and characteristics such as time to ignition, flame spread (propagation rate) and characterization of the residue are determined.
Structure of qinsun 45 degree flammability tester:
Flowmeter :Adjust the gas flow size;
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 pipe;
Windscreen: the upper part of the windshield is provided with glass;
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.
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;
Reset :Timer reset /Fire tube reset;
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;
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;
