Electronic level HCL
First, product introduction
Hydrogen chloride is a colorless, toxic, corrosive, non burning gas, a asphyxiant odor, strong irritation to the upper respiratory tract, eye, skin, and skin.
The mucous membrane is corroded. The proportion of hydrogen chloride is greater than that of air, and it produces white smoke in wet air. It does not react with water but easily dissolves in water, and hydrochloric acid is chlorine.
The aqueous solution of hydrogen is a colorless or yellowish liquid. The air is not burning, the heat is stable, and it is decomposed at about 1500 degrees C. Mixed with ethylene
An explosive gas.

Four, the application of hydrogen chloride
It is a very important basic raw material in the chemical industry. It is widely used in the production of medicine, pigment and plastics.
High purity hydrogen chloride is mainly used in the development of silicon epitaxy, gas phase polishing, etching and clean treatment in the production of large-scale integrated circuits.
Five. Precautions
The hydrogen chloride meets the wet air to smoke and dissolves in the water to produce a large amount of heat, forming a highly corrosive hydrochloric acid. An irritating sour taste
It can be detected at very low content (<5ppm). Direct contact with the skin can cause severe burns. The leakage of hydrogen chloride should be rapid
Evacuate the leak pollution area personnel first wind, and immediately carry out isolation, small leakage of 150m isolation, large leakage of isolation 300m, strictly limited
Go in and out. It is suggested that the emergency treatment personnel wear self-sufficient positive pressure respirator and wear chemical protective clothing. Enter the scene from the upper wind. Cut off the leakage source as much as possible.
Reasonable ventilation and accelerated diffusion. Neutralization of ammonia or other dilute lye. To build a large number of wastewater barrierpit to contain the. If possible, will
The residual gas or leakage gas is sent to the water washing tower or the ventilator connected to the tower by the exhaust fan. The gas leakage container should be properly treated, repaired and reused after inspection.
A steel bottle cylinder inspection time, does not meet the requirements of the cylinder should be entrusted ferrill specialty gas supplier to the pressure vessel inspection qualified
The unit is tested. The use of overdue steel bottles is strictly prohibited.
