Anticorrosive processing of a body. Anticorrosive treatment of the bottom of the car. Anticorrosive materials

The domestic car industry readily absorbs alltechnologically the charm of the world industry. This process is expressed in the fashionable editions of the exported versions of the best Togliatti models, and in the general enthusiasm for new electronic assistants. But there are a lot of Russian traditions in this sphere, which are still quite relevant today. Means of combating the rust of the body just this and belong. It is another matter that modern methods of combating metal damage seriously differ from Soviet "recipes". So, if up to the 90s the metal was covered with tar and rubber bituminous mastic, today the anti-corrosion treatment of the body provides for a wider range of effective techniques.

Principle of action of anticorrosive

To begin with it is necessary to be defined, from whatthe car body must be protected. Of course, first of all, this is contact with water, which can penetrate the paintwork. But the rusting process usually starts at the places where the metal contacts the foreign materials, as well as with the electrolyte. Accordingly, any anti-corrosion treatment of the body of the car is primarily aimed at sealing the base. The effect of isolation is achieved in different ways, but the main task is to prevent contact of the surfaces of the structure with other materials. This does not mean that the entire body must be reinforced with an anticorrosion. Most of the area is completely preserved under the factory layer of paint and varnish. Additional processing is required in the most vulnerable areas, including door racks, spars with thresholds, wheel arches, etc.

Which cars are suitable for?

In Russia, the popularity of anti-corrosion treatmentis associated with a prolonged nature of the operation of cars, while Europeans change their cars every three years. If you plan to quickly change used foreign cars or domestic novelties, then in such operations there is no sense. Another thing is that the anti-corrosion treatment of the body is necessary in cases of mechanical damage to its elements. Even the slightest break-off requires adequate protection. It is important to take into account one more aspect - the presence of the factory plast-polymeric protection, which lasts 2-3 years. If the road reagents and abrasives can not start the reaction during this time, this indicates a high quality of the protective layer. But you do not have to put special hopes on staff funds either. When calculating the long-term use of the machine still it makes sense to turn to special services in the car service.

How is the anti-corrosion treatment of the body performed?

Much depends on the specific material thatIt is planned to cover the body, but in most cases, the execution algorithm is the same. First of all, a surface is prepared. Experts clean the machine and carefully dry it. If there are traces of previous processing, they are deleted. Next, a new tool is applied - again, the processing techniques can be different. For example, the paint is applied with spray guns, and the mastics are applied with special spatulas. The main thing is that the anti-corrosion treatment of the body covers all the problem areas. After that, the "working" zones will dry for several hours.

What materials are used in the processing?

In the market you can find a huge selection of differentmeans of protection. The most common options include paint, mastics, films and primers. The application of film coating, from the point of view of sealing, is a good solution, but the smallest damage can lead to a sad result. Quite good reviews are obtained by bituminous mastics, wax mixtures and anticorrosive materials on a synthetic basis. But here each manufacturer has its own brand composition, the effectiveness of which is to a large extent determined by additives in the form of bronze, zinc, rubber and polymeric impurities. The advantages of combined means include the fact that they can counteract both corrosion and other destructive processes. As a result, the overall service life of the vehicle's load-bearing elements is extended.

Anticorrosive protection for the bottom

The bottom requires special protection, since this partis exposed not only to the effects of chemical properties, but also to mechanical damages. Accordingly, the film and varnish-and-paint compositions are completely rejected. Perhaps the use of mastics, but only from the category of strongly hardening. The most effective solution to protect this part is a multilayer coating comprising a mixture of phosphates supplemented with inclusions of aluminum or zinc. An anticorrosive paint with protection from a primer or the same mastic is also applied here. As a result, a kind of "pie" is implemented, capable of protecting the bottom from both corrosion processes and physical damage. The most radical way to protect this part of the car involves the installation of protective plates from the same combination of zinc and aluminum. But such structures are expensive and in all variations require regular updates.

Price issue

Car repair services in most cases offer twoapproach to processing. The first provides full protection of the car, and the second - a partial adjustment of the state of problem areas. Means are used about the same, and the cost depends on the class of the car. For example, a compact A-class can be partially ennobled for 5-7 thousand rubles. For off-road cars, it is usually recommended full anti-corrosion treatment, the price of which varies from 10 to 15 thousand rubles. The protection of hidden and inaccessible elements, to which the exhaust system, fenders and thresholds belong, is separately assessed. But in such cases and means the most effective ones are used - for example, thermolac, anigravine films and liquid lockers. The cost of such protection is 3-5 thousand rubles.

Conclusion

anticorrosive materials

A good help for the function of protective coatingswill become and careful nature of the car. Supporting the body in a clean, timely restoration of the paintwork and sparing use of the car in bad weather - these are the main preventive measures available to any driver. Of course, anti-corrosion protection contributes to the prevention of destructive metal processes, but it may not be enough. In any case, compliance with preventive measures will increase the intervals between renewals of rust-preserving coatings. Also do not forget that every body repair must be accompanied by a special treatment of the damaged area, whether it is the formation of a small cleavage, or the formation of a welded seam.
