Agent for cleaning out oil stain on road surface of airport

Abstract

This invention discloses a method for preparing a detergent for cleaning airport runways. The detergent is composed of: orange oil 70-80 parts, sodium dodecyl benzenesulfonate 10-15 parts, potassium pyrophosphate 12-20 parts, triethanolamine 1-3 parts and deionized water 100 parts. The detergent uses orange oil with 80% or more limonene as the major component, which is added with multiple surfactants. The detergent has a low surface tension, thus can effectively remove oil stains on airport runways without any corrosion. Since orange oil is a natural extract from orange peels, it has no harm to the environment or human health. Besides, the detergent is not combustive or explosive, thus is safe for usage. Since the volatilization rate of the detergent is low, it can be recovered after cleaning, and recycled after distillation, thus lowering the cost. The method for preparing the detergent is simple.

Description

technical field [0001] The invention relates to an airport pavement oil stain cleaning agent and a preparation method thereof, in particular to an airport pavement oil stain cleaning agent using natural plants as main raw materials and a preparation method thereof. Background technique [0002] With the rapid development of the aviation industry, the number of aircraft is increasing rapidly, and the parking berth area of ​​each airport is also constantly expanding. In order to ensure the safety of passengers, when the aircraft is parked at the berth, the operator usually needs to carry out normal maintenance. During this process, some oil will drip on the ground of the berth, which will not only affect the external environment of the entire airport, And if these oils happen to cover the white lines on the airport runway, the pilot may not be able to get in place accurately when the plane lands because the white lines cannot be seen clearly, which may cause accidents. At pre...

Problems solved by technology

In order to ensure the safety of passengers, when the aircraft is parked at the berth, the operator usually needs to carry out normal maintenance. During this process, some oil will drip on the ground of the berth, which will not only affect the external environment of the entire airport, And if these oils just cover the white line on the airport runway, the driver may not be able to get in place accurately when the plane lands because the white line cannot be seen clearly, thus there is a hidden danger of accidents

At present, water-soluble detergent type solutions are mainly used in China to clean these oil stains, but the problem is that they are not thorough, that is, the oil stains cannot be completely absorbed, and as a result, there are still traces of oil stains on the road surface. phases are not miscible at all

If it is cleaned with chemical solvents, it will cause harm to the safety of the airport and cause environmental pollution due to inflammability and explosion. However, washing with high-pressure water cannot completely remove oily substances, and it will also cause serious waste of water resources.
