How is the ignition point of solids measured?
Thread Content
Does that guy know what the ignition point of solids refers to? What is a definition? How can it be measured experimentally?
Combustible solids, liquids, or gases, when in contact with air and at a certain temperature, will catch fire upon exposure to an ignition source； It can continue to burn even after the source of fire is removed. The lowest temperature required for a combustible material to begin burning continuously is called the ignition point. The ignition points of several commonly used substances in households are shown in the table. For example, to light a coal ball stove, one first uses a match to light the paper; the paper then lights the wood shavings, and the wood shavings in turn light the coal balls. This shows that each material has a different ignition point. Ignition points of several substances: Name, Ignition point (°C); Name, Ignition point (°C). Coal, Oil – 86; Nylon fibers, 390; Turpentine, 53; Painted cloth, 165; Celluloid, 100; Wax, Candles – 190; Rubber, 130; Cloth, 200; Paper, 130; Soybean oil, 220; Cotton flowers, 150; Tobacco leaves, 222; Flax fibers, 150; Pine wood, 250
Sir upstairs, what I’m asking is how to determine the ignition point of solids. Hey, guys from Haichuan – this question has really stumped everyone!
The ignition point of a solid is measured using a thermogravimetric analyzer; on the weight loss curve, the temperature at the intersection of the two tangents is roughly the ignition point temperature. 3# xxchenjz
