Description

A kind of gas leak detection agent of aircraft
Technical field
The present invention relates to a kind of gas leak detection agent, more particularly to a kind of civil aircraft routine testing that is used for is safeguarded and daily dimension Gas leak detection agent during repairing.
Background technology
Aircraft is in high-altitude flight, atmospheric pressure reduction, the oxygen partial pressure reduction of human body suction, and human life is made safely Into threat.The effect of oxygen system is exactly preventing high altitude anoxic, bad physiological reaction caused by low pressure effect.It is standing on aircraft Oxygen system have three kinds, respectively driving cabin supplies the pressure breathing system of crew;Passenger and service on buses or trains are supplied in main cabin The chemical oxygen generators of member;Carry-around oxygen bottle is on the aircraft of cabin pressurization, for first aid and some particular/special requirements Personnel.All pipe interfaces and valve in oxygen system, are required for carrying out leak detection work, general leak hunting method has two kinds, Listen air-tightness, if having " whooshing " sound;Using leak-checking agent, leak understands product continuously bubble.
With listening, the method reliability of air-tightness is not strong, and can not be accurately positioned gas leak;Presently used leak-checking agent In, it is diluter to there is solution concentration, is unfavorable for the problem of it is attached to around joint.
The content of the invention
It is an object of the invention to provide a kind of gas for during the maintenance of civil aircraft routine testing and ordinary maintenance Leak-checking agent.
A kind of aircraft gas leak detection agent, by the material composition of following parts by weight:0.2-20 parts of surfactant, anti-corrosion Lose 0.1-2 parts of agent, sterilized inhibitor 0.1-2 parts, 76-99.6 parts of solvent.
The surfactant is lauryl sodium sulfate, OP-10, AES, cocounut oil acyl methyl taurine sodium, Sorbitan One or more in alcohol laurate.
The anticorrosive is the one or more in BTA, sodium gluconate, sodium metasilicate.
The sterilized inhibitor is the one or more in Sang Pu IPBC- II, outstanding horse A, Kathon CG, Sang Pu G.
The solvent is deionized water and ethylene glycol.
Compared with prior art, the present invention has the advantages that:Gas leak detection agent product not oil-containing, the silicon of the present invention And hazardous solvent, it can quickly, reliably position the gas of aero tyre, aircraft high and low pressure oxygen system and other oxygen systems Body leak, and aircraft materials are not damaged, it is harmless to human body using rear noresidue.The surfactant component energy of addition Quickly, the gas leak of aero tyre, aircraft high and low pressure oxygen system and other oxygen systems is reliably positioned, is connected Continuous bubble.The sterilized inhibitor composition of addition can effectively suppress flourish and the breeding of bacterium, and with certain sterilized work With mould test can be passed through.The anticorrosive composition of addition can ensure that the security performance of aircraft materials, corrosion-free.
