Description
Technical field
The present invention relates to a kind of outer railway carriage sanitising agent of Railway System locomotive that is used for, more particularly relate to the neutral liquid cleaning agent of the outer railway carriage of a kind of motor-car.
Background technology
Motor-car in the fast running process, outer railway carriage dirt main composition: 1) animal subacidity organisms such as birds movement and insect; 2) sand and dust, the clay kicked up of train high-speed cruising also has fine powdered carbon, iron powder, metals ion or metal oxide solid, 3) the oiliness greasy dirt, 4) rust staining of other various mixed dirts and formation thereof.And these dirts are trapped in lily EMUs outside surface, seem painted responsive especially to polluting, if in time do not wash removing, can quicken its yellowing and lose gloss of film.If but arbitrarily use washing composition, although the motor-car vehicle body coating is to protect light tint retention polyurethane finish preferably, the accelerated deterioration even the yellowing that also may bring the pure white coating surface.More long-range consideration be, be mainly duraluminum and stainless EMUs for the body construction material, in case the protectiveness paint film on it damages to some extent, then just be easy to produce corrosion.To motor-car surface different sites, the different characteristics of dirt needs suitable sanitising agent and cleans.
To the large-area cleaning of locomotive car body, use neutral liquid cleaning agent more, mainly utilize mechanism such as SURFACTANT ADSORPTION, emulsification, dispersion, reach good clean effect.This decontamination mode performance is gentle, does not contain the acid-basicity compound, to locomotive surface non-corrosiveness.Preferred biodegradability surface of good promoting agent, environmentally friendly.The mild detergent detergency ability that is used for locomotive surface big area cleaning at present is good; But because the tensio-active agent selection is reasonable inadequately; Corrodibility to duraluminum is more serious, and motor-car locomotive aluminum alloy spare part is had stronger corrosive nature, has reduced the work-ing life of this part parts of motor-car.
Clean the dirt characteristics that motor-car should produce according to motor-car in operational process fast, will consider that also cleaning product does not produce corrosive nature to motor-car surface paint, parts, the motor-car paint after the cleaning is wanted light as new; Detergent for washing car can not cause any corrosion to other parts of motor-car; Simultaneously, the chemical ingredients of cleaning product and easy washability all should meet direct minimizing water usage quantity and environmental protection requirement.The neutral liquid cleaning agent of the outer railway carriage of a kind of motor-car of the present invention is according to the corrodibility evaluation, and its outward appearance corrodibility is 1 grade, and etching extent is 1～2mg; And present commercially available sample outward appearance corrodibility under similarity condition is 3 grades, and etching extent is 7mg.
