Why does a match catch fire as soon as it is struck? What is used to extinguish a diesel fire

The match head mainly contains potassium chlorate, manganese dioxide, sulfur and glass powder. The matchstick is coated with a small amount of paraffin. The friction layer on both sides of the matchbox is made of red phosphorus and glass powder.

The main processes of match ignition are: (l) when the match head is struck on the matchbox, the heat generated causes phosphorus to burn; (2) The heat emitted by phosphorus combustion decomposes potassium chlorate; (3) the reaction of oxygen liberated by potassium chlorate with sulfur; (4) The heat emitted by the reaction of sulfur and oxygen ignites the paraffin, which eventually ignites the matchstick.

Because the match head contains a substance with a low ignition point, it will catch fire if it is rubbed slightly.

2 points will be awarded for the first time, and reward points and an additional 20 points will be awarded for the answer. Firewood contains substances with low ignition points, and a little rubbing can catch fire.

Frictional heat generation makes it easy for the chemicals on the match to reach the ignition point.

What should I do if a diesel drum catches fire? What fire extinguisher should I use?

If a diesel drum fires are not available, they can be crushed with sand, loose soil, or any covering of the non-flammable plant or the air can be sealed. However, do not splash water to extinguish the fire to avoid boiling and other combustibles.

What fire extinguisher is used to extinguish oil fire?

Oil** is a Class B fire, and the applicable fire extinguishers are as follows:

1. Stem ammonium phosphate dry powder fire extinguisher, Huixiao [commonly known as ABC dry powder fire extinguisher];

2. Sodium bicarbonate dry powder fire extinguisher [commonly known as BC dry powder fire extinguisher];

3. Foam fire extinguisher (depending on the type of oil, some cannot be extinguished);

4. Carbon dioxide fire extinguisher (it is recommended to use the fire area less than 5 square meters);

For example, oil tanks**, it is necessary to use a large amount of fire rolling water to cool the tank, and at the same time call 119 for rescue;

Since ABC dry powder fire extinguishers are commonly used in solid, liquid, gas, and live fires, it is recommended to configure ABC dry powder fire extinguishers in mixed places, which are simple to maintain and easy to use.

Oil fires are more difficult to extinguish, and easy to lead to deflagration, and even **, it is recommended to properly store in accordance with the specifications, or from the perspective of preventing fire sources, and the tank is recommended to be placed underground safer.

What to do if diesel gasoline catches fire.

The combustion of oil can not be extinguished with water, it is necessary to extinguish the fire by suffocation, if there is a dry powder fire extinguisher, it is sprayed with a dry powder fire extinguisher, and carbon dioxide gas can also be used, but the effect is not very good. The best and most cost-effective way to find more people to cover up the burning oil with sand and dirt. Ding Guo has an oil tank and must have the idea of cooling the tank to prevent high temperature**.

Diesel engine fire, what fire extinguisher to apply.

The oil in the pot should be extinguished with a lid and must not be extinguished with water, because the density of the oil is smaller than whom, and watering will make the oil continue to burn on the surface of the water Dry powder fire extinguisher can extinguish general fires, and can also extinguish fires caused by the combustion of oil and gas. Dry powder fire extinguisher uses carbon dioxide gas or nitrogen gas as the power to spray out the dry powder in the cylinder to extinguish the fire. Dry powder is a dry, easy-to-flow fine solid powder, composed of a base material that can extinguish fires and additives such as moisture-proof agents, flow accelerators, and anti-caking agents.

It is mainly used to extinguish flammable liquids such as petroleum and organic solvents, combustible gases and electrical equipment. Dry chemical fire extinguishers are divided into three types: portable, backpack and cart according to the way of movement.

Which is better to extinguish a fire, gasoline or diesel.

Although gasoline is more volatile than diesel, it is equally easy to extinguish a fire when both oils are ignited.

What are the reasons for the fire caused by the combustion of gasoline, kerosene, and diesel, which generally cannot be extinguished with water.

Because the density of oil and water is not the same, they will not be integrated when they are put together, so the water cannot dilute it when burning, and when adding water, it can only float on the water surface and increase with the flow of water before combustion. You can use a glassware filled with oil and water.

Why can't fires caused by gasoline and diesel be extinguished with water?

Not only oil, but when the fire is fierce, the water will burn and differentiate into hydrogen and oxygen, which will strengthen the fire!

What fire extinguisher is used for diesel?

dry powder, carbon dioxide, river sand.

1. The reason why the match catches fire as soon as it is wiped is that the bulging match head is sulfur and potassium chlorate.

For example, the matchstick is made of poplar or pine, and the matchbox is coated with red phosphorus.

and glass powder, etc. When you rub a match on the edge of the matchbox, the match head is stained with some red phosphorus, and when the red phosphorus is rubbed and heated, it will spark and ignite the potassium chloride and sulfur on the match head.

2. The firewood holding on the base of the fire has friction matches (also known as phosphorus sulfide matches) and safety matches.

The principle of ignition is not the same. The main components of the friction match nozzle are potassium chlorate and tetraphosphorus trisulfide, and the heat generated by a slight friction on the rough surface is enough to cause a chemical reaction between the two substances.

And angry. Ankongqing uses sulfur to replace tetraphosphorus trisulfide in the match head. The general frictional heat is not enough to make the medicine head react, only when the phosphorus layer on the side of the matchbox is scratched, the frictional heat first causes the sulfur to react with potassium chlorate, releasing more heat energy, and promoting the chemical substances in the medicine head to react and ignite.

1. The reason why the match catches fire as soon as it is wiped is: the puffed match head is sulfur and potassium chlorate, etc., the match stick is made of poplar or pine, and the matchbox is coated with red phosphorus and glass powder. When you take a match and rub it on the edge of the matchbox, the match head will be stained with some red phosphorus, and when the red phosphorus is rubbed and heated, it will spark and ignite the potassium chlorate and sulfur on the match head.

2. Matches are divided into friction matches (also known as phosphorus sulfide matches) and safety matches, and their ignition principles are not the same. The main components of the friction match nozzle are potassium chlorate and tetraphosphorus trisulfide, and the heat generated by a slight friction on a rough surface is enough to cause a chemical reaction between the two substances to ignite. Sulfur is used instead of tetraphosphorus trisulfide in safety match heads.

The general frictional heat is not enough to make the medicine head react, only when rubbing on the phosphorus layer on the side of the matchbox, the frictional heat first causes the sulfur to react with potassium chlorate, releasing more heat energy, and promoting the chemical substances in the medicine bucket base grip to react and ignite.
