Automobile and others transportation industry.
  At present, there are many different types of cleaning agents for automobiles, external cleaning agents and automotive air-conditioning cleaning agents are mainly used. When engine of the car is running, it continuously radiates outwards, and suffered from the attack of external sand and dust, so it is easily to deposited dirt; due to the long-term operation of the engine, impurities such as carbon deposits and dirt are generated, which affects the performance and safety of the engine. For air-condition system, due to it’s running for long time, so need to be cleaned on time, if not, there will produce a large of dust, bacteria and so on, which are harmful for our heath. So completely cleaning is very important. APG is widely used in this filed.
 Cleaning inside and outside of the engine. The researchers developed a waterborne carbon deposit cleaning agent for automobile combustion chambers, composed of APG, Gemini surfactant, and imidazoline corrosion inhibitors and additives. The surface tension of this cleaning agent is about 26x103N/m. It has the characteristics of mild nature and good cleaning effect, and no corrosion for steel, aluminum and rubber materials. the researchers also developed a high-temperature carbon deposit cleaning agent for the combustion chamber of all-aluminum engines, composed of organic boronamide 10%~25%, APG (C8~10, C8~14) 0.5%~2%, and inorganic alkali 1%~ 5%, deionized water 68%~88.5%. as well as an external engine cleaning agent, by APG (C12~14, C8~10), AEC
And alcohol ether and chelating surfactants (lauryl ED3A and palmitoyl ED3A) compounded with dispersant, rust inhibitor, a small amount of small molecule alcohol and so on. Its decontamination power is about 95%. It has the characteristics of environmental protection and high safety. APG is not turbid or flocculated under strong alkali, which is conducive to the continuous stability of the system. For the cleaning of automotive evaporators, researchers have developed nonionic surfactant APG is compounded with Span, NPE, isomerized alcohol polyoxyethylene ether carboxylate, and anionic surfactants AES, SAS and N-lauroylsarcosinate sodium and chelating agent and corrosion inhibitor are added to prepare multi-effect cleaning agents for cleaning and bacteriostatic functions of automobile evaporator, which have achieved good results. Under other conditions basically unchanged, the use of APG has better bacteriostatic effects. Others such as automobile surfaces, aircraft outer surfaces and train steering systems clean. The researchers developed a train head shellac cleaning agent compounded with APG, AEO, LAS, and NPE, supplemented with citric acid, STPP, and defoamer. The cleaning rate is 99%, which is suitable for cleaning the surface of the ends of various rail transit trains, especially the cleaning of the dirt such as gums stuck on the windshield of the end of the car during high-speed operation.
The researchers developed a biodegradable cleaning agent that removes the outer surface of the aircraft such as the fuselage, glass, rubber, etc., which is composed of HLB value of 10~14 FMEE, APG, cosolvent, alkali metal silicate and rust inhibitor, etc. And developed the cleaning agent for the train steering device, which is composed of APG, isooctanol polyoxyethylene ether phosphate, Tween, etc., as well as the integration agent EDTA-2Na, sodium citrate, etc. Its cleaning efficiency is as high as 99%. It fills the gap of market of compatible cleaning of oil and dust products on various types of trains and their steering devices, which is safe and does not hurt the substrate.
