12.4. Anticorrosive protection of a body

Bearing hollow profiles of a body, the bottom, the bottom parts of doors, racks, and also connections of details of a body, including a spot welding place are most of all subject to corrosion.

Quickly corrosion develops in the latent cavities and the bottom parts of a body at hit on a surface of a moisture, a dirt, salts, acids.

In this connection while in service the car additional protection is required: internal surfaces and the latent cavities of a body – drawing of special anticorrosive structures, and connections of details – drawing of sealing mastics.

Applied materials for anticorrosive processing are specified in the table. Autopreservative «МОВИЛЬ» is used for processing of the latent cavities. It is recommended to process cavities every 1-1,5 year. Processing of surfaces, before covered нигролом and other oils, and also rusty surfaces is supposed.

Protective lubricant of NGM-ML is applied at processing of the latent cavities. This material processes cavities of all new cars.

Protective film covering НГ-216 Would be used for a covering of parts of the car under a body.

Mastic antinoise bitumen БПМ-1 is applied to protection against corrosion of the bottom of a body and for reduction of noise of vibration. Put mastic dispersion or manually in the thickness of 1,0-1,5 mm.

Пластизоль Д-4А it is applied to hermetic sealing of welded seams on external zones of a body.

Non-drying mastic 51-G-7 is used for hermetic sealing of joints of a body.

In internal cavities anticorrosive substance напыливается in the way of air or vacuum dispersion.

At air dispersion compressed air with pressure 0,5–0,8 МПа, a pistol-kraskoraspylitel with a tank, hoses and the extended nozzles for a pistol is required. Better quality of a covering is reached at vacuum dispersion under the pressure of 4–12 МПа which allows to spray materials of considerable viscosity.
