Have you ever noticed the clean and beautiful appearance of the plane when you fly? As a means of public transportation, the cleanliness of the airplane is directly related to the travel experience of each passenger and the safety of the airplane, so cleaning is essential.

Airplanes are high-value vehicles composed of various components with different properties and performance. Among them, the aircraft shell is made of aluminum alloy as the main material, with a part of high tensile polymer materials and steel. After a long-term high-altitude flight of an aircraft, the outer shell is adhered to by fuel combustion gas, various suspended particles in the air, and dirt in the sky, and various physical and chemical reactions occur. Smoke and dust will be deposited on the outer surface and components. , Oil, carbon, oxides and rubber. These deposited pollutants not only increase the weight of the aircraft, affect the appearance of the aircraft, but also reduce the surface finish of the aircraft and increase the frictional resistance, and often become an inducing factor for aircraft corrosion. The abdomen, wings, and hydraulic systems of the airplane are so many that dust and sewage are easy to stick to them. The vertical tail has a rudder. If it is not washed for a long time, it will cause blockage and corrosion of the mechanical parts.

Therefore, in every airline, "bathing" the aircraft is an essential task. Generally speaking, an aircraft needs to be cleaned every 3 weeks to 1 month.

When cleaning, it can not cause corrosion and damage to the aircraft shell, so the selection of tools and materials is particularly important. At present, there are two commonly used aircraft cleaning agents, one is alkaline water agent and heavy-duty cleaning fluid, and the other is alkaline cleaning agent containing abrasives. Both of these cleaning agents can clean the aircraft shell and play a protective role in corrosion protection. When cleaning the shell, a ladder is put on the plane. After fixing it, the cleaner fastens the seat belt on the ladder, and then takes the tools to lie on the ladder for cleaning. Before cleaning, first observe whether there are pits and scratches on the exterior, and make sure that the nose windshield and the cabin door are closed. Then use a condom to cover the wheels of the aircraft, as well as the aircraft hub and engine. At this time, the cleaner evenly spread the cleaning agent on the aircraft shell, let the shell soak for 5-10 minutes, and then wipe it with a washing machine rod wrapped in a towel, and then use a brush to strengthen cleaning and waxing in some places.

"You need water to wash the airplane. If the temperature is too low, it will easily freeze. So the temperature is lower than 4℃. It will not be washed. It will not be washed for the whole winter." It can not be washed in winter for three months. How to keep the airplane The body is clean? The answer is: polishing and waxing the whole machine! Lv Liguo, an "old master" who has been an "aircraft beautician" for 20 years, introduced "Any cleaning, polishing and waxing of aircraft must be carried out on the premise of aircraft safety, because the use of polishing machines has certain risks, so we are all Manual operation, you can’t use the machine like other people washing cars.” Because it’s all manual operation, polishing and waxing an airplane is a lot of work. “It takes 10 people to do 6-8 hours, but a clean body after waxing Keep it for 3 months."

The composite raised cloth melamine sponge developed by Xiamen Sihang is a new type of aircraft shell cleaning brush, which is made of high-density nano-sponge bonded with raised cloth. It has the characteristics of strong cleaning power and durability. It uses micro-grinding technology to penetrate deep into the micro pores and quickly remove stubborn dirt. Only clean water is required. It is a new type of cleaning material for aircraft shells.

        ● Micro grinding technology: extremely fine particles, leaving no scratches, quickly removing stubborn dirt;

        ● Pure physical cleaning: only clean water, easy to clean, suitable for uneven surface;

        ● Raised cloth bonding: Reinforce the sponge, bonding Velcro tools.

Xiamen Sihang's composite fluffing cloth melamine sponge quickly removes aircraft dust, dirt, and grease. It only requires clean water and no detergent. It is a new and easy-to-use aircraft cleaning product. High density, good toughness, can directly pinch water by hand; wear-resistant, durable, not easy to break, slag, good cleaning effect, is widely used in major airport aircraft shell cleaning.
