Abstract
The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for an airplane vacuum toilet system, which comprises the following components in percentage by mass: 5-20% of organic chelating agent, 0.2-3% of composite surfactant, 0.5-5% of corrosion inhibitor, 0.1-2% of other auxiliary agents and the balance of pure water, wherein the organic chelating agent is one or a mixture of more of diethylenetriamine pentaacetic acid, diethylenetriamine pentaacetic acid pentapotassium, dicarboxymethylalanine and dicarboxymethylalanine trisodium, the composite surfactant is a mixture of more than two of fatty alcohol polyoxyethylene ether AEO-9, isotridecanol polyoxyethylene ether 1309, cocamidopropyl betaine and dodecyl dimethyl amine oxide, and the corrosion inhibitor is one or a mixture of two of octyl phosphoric acid, dodecanoic acid and nonanoic acid. The invention has good cleaning and removing effect on dirt in the airplane closestool system, does not cause adverse effects such as corrosion on various metal and nonmetal materials on the airplane and various coatings and surface treatment layers of the materials, and is safe and reliable.
Description
Technical Field
The invention relates to the technical field of cleaning agents, and particularly relates to a cleaning agent for an airplane vacuum toilet system.
Background
At present, the mainstream type closestool sewage treatment systems of civil airliners are vacuum type treatment systems. The system utilizes a water source to flush the used closestool, then discharges the closestool under the action of system vacuum so as to maintain and provide a clean sanitary environment, simultaneously concentrates sewage in a sewage tank, and treats the sewage through ground service after an aircraft lands.
Scales such as water scales, soap residues, urine alkali and the like are easily generated on a sewage pipeline and a toilet bowl wall of the system, the flow rate of the pipeline is easily reduced due to the accumulation of the scales, and even the pipeline is blocked in serious cases, so that the system fails and the environment in an airplane cabin is influenced. Aircraft are special vehicles, and safety is the most important requirement. As a cleaning agent for aircraft maintenance, the cleaning agent has good cleaning and descaling effects and simultaneously needs to have no corrosion and adverse effects on various metal and non-metal materials of a system so as to ensure the safety and reliability of the aircraft.
The traditional toilet cleaning agent has various types, is generally used for cleaning a toilet system of household or ground facilities, has certain corrosivity on metal and non-metal materials, and cannot meet the requirement of an airplane on the safety of maintenance chemicals.
Through searching, the following patent publications related to the patent application of the invention are found: for example, the application number CN201210251535.7 discloses a matching type cleaning agent for vacuum sewage pipelines of airplane toilets, a preparation method and a cleaning process thereof, wherein the cleaning agent is formed by matching a cleaning agent I and a cleaning agent II, and the cleaning agents are synergistic to clean in stages. Firstly, cleaning by using a cleaning agent I, wherein the cleaning agent I is an acidic thixotropic cleaning agent, has good wall-hanging property, has good removal effect on scale on the inclined plane or the vertical plane of a pipeline system, and can be used for pipeline leakage detection; and then, the cleaning agent II is used for cleaning, and has the advantages of small viscosity, good fluidity and strong detergency.
However, the cleaning agent for the airplane toilet system in the prior art generally adopts strong acids such as hydrochloric acid and phosphoric acid as main components for descaling and cleaning, and although the cleaning agent has a good cleaning agent effect, the cleaning agent has strong corrosivity on various metal materials on an airplane and does not meet the safety requirement of airplane materials, and the strong acids are dangerous chemicals and have huge corrosion danger on human bodies, so that the cleaning agent has great potential safety hazard when stored in the closed environment of the airplane.
In view of the above, the present application particularly provides a cleaning agent for an aircraft vacuum toilet system to solve the above technical problems.
Disclosure of Invention
The invention provides a cleaning agent for an airplane vacuum closestool system, which has good cleaning and removing effects on dirt in the airplane closestool system, does not cause adverse effects such as corrosion on various metal and nonmetal materials on an airplane and various coatings and surface treatment layers of the materials, and is safe and reliable; the cleaning agent can be used for cleaning toilets and pipelines in an airplane vacuum toilet system, meets the requirements of a plurality of airworthiness standards, and is safe, reliable and environment-friendly to use.
