Problems solved by technology

[0003] The method of listening to air tightness is not reliable, and it is impossible to accurately locate the gas leak; in the current leak detection agent, there is a problem that the concentration of the solution is relatively dilute, which is not conducive to its adhesion around the joint

Abstract

The invention discloses a gas leakage detecting agent for an airplane, which is composed of the following materials in parts by weight: 0.2-20 parts of a surfactant, 0.1-2 parts of an anticorrosive agent, 0.1-2 parts of a bactericidal inhibitor and 76-99.6 parts of a solvent. The gas leakage detecting agent does not contain oil, silicon or other harmful solvents, and can position a gas leakage part of an airplane tire, an airplane high-pressure oxygen system, an airplane low-pressure oxygen system and other oxygen supply systems quickly and reliably. In addition, the gas leakage detecting agent does not damage airplane materials, has no residue after usage and has no harm to the human body.

Description

technical field [0001] The invention relates to a gas leak detection agent, in particular to a gas leak detection agent used in the routine detection and maintenance of civil aircraft and the daily repair process. Background technique [0002] When the aircraft is flying at high altitude, the atmospheric pressure decreases, and the partial pressure of oxygen inhaled by the human body decreases, which poses a threat to human life safety. The role of the oxygen supply system is to prevent adverse physiological reactions caused by high altitude hypoxia and low pressure effects. There are three kinds of oxygen supply systems standing on the plane, namely, the pressurized oxygen supply system for the crew in the cockpit; the chemical oxygen generator for the passengers and flight attendants in the cabin; First aid and some special requirements personnel. All pipeline connections and valves in the oxygen supply system need to be leak detected. There are two general leak detectio...
