What is Portable Dangerous Liquid Detector？
Science promotes economic development and social progress. When mankind is creating history, there will also be bad materials. There will be good and bad things, and everything has its own yin and yang.
Dangerous liquids have the same yin and yang side, such as ethanol. It is a flammable substance that is forbidden to be carried into airplanes, but it is our women’s favorite perfume, sterilizing medical supplies necessary for doctors, and gasoline. He should be The important liquid that makes the machine work and makes the car start can burn when it comes into contact with the gas volatilized from the air or it encounters a small amount of sparks.
So what causes these items to be classified as dangerous liquids?
The answer is because they all contain flammable and explosive substances and these dangerous liquids include: gasoline, diesel, kerosene, absolute ethanol, acetone, benzene, banana water, ether, dichloromethane, trichloroethylene, petroleum ether, turpentine, Liquid paraffin, toluene, xylene, ethyl acetate, n-butanol, dichloroethane, n-pentane, cyclohexylamine, cyclohexane, carbon disulfide, methanol, isopropanol, ethylenediamine, nitromethane, liquid Flammable and explosive liquids such as explosives (IED).
Any liquid containing these substances should not be brought to public places where the human body gathers. Dangerous liquids that are forbidden to be carried include: hairspray, perfume, cologne, sunscreen spray, non-flammable non-toxic gas used in sports or household aerosols without secondary hazards, etc.
In order to prevent criminals from carrying these dangerous liquids into public places with a large flow of people, such as airports or railway stations, and bus stations, a Liquid Detector that specifically recognizes these dangerous liquids is designed to prevent dangerous incidents from happening.
The principle of hazardous liquid detector is mainly for plastic, glass, and ceramic containers. The instrument adopts the magnetic flux leakage method and uses different materials with different dielectric properties. After the liquid bottles with different components are placed in the electrostatic field, the induced electric field and other output changes are detected. , To determine whether the liquid is dangerous in turn; for the detection of aluminum and iron metal containers, according to the different thermal conductivity of different components of the liquid, the temperature rise is obtained as a function of time by measuring from the time the heating power is turned on. The thermal conductivity of the sample material is based on this principle to distinguish whether the liquid product is dangerous or not by sensing the output change. The above detection methods are all non-intrusive safety inspection technologies, which can realize safety inspection without opening the package, and have no impact on the health of operators.
The material of the detectable container is capable of inspecting liquids in plastic containers, glass containers, ceramic containers, and aluminum and iron metal containers.
The dangerous liquid checker can detect more than 30 kinds of dangerous liquids, including gasoline, kerosene, diesel, hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide, potassium hydroxide, isopropyl ether, petroleum ether, propionaldehyde, benzene, carbon disulfide , N-hexane, isopropanol, nitromethane, diethylamine, chloroform, ethylene glycol, xylene and other flammable and corrosive liquids, even dilute sulfuric acid, dilute hydrochloric acid and Dilute nitric acid can also be tested with 100% accuracy.
The hazard checker is suitable for factories such as airports, docks, railway stations, subways, bus stations, public security bureaus, fire stations, courts and other agencies, embassies and consulates abroad.
