The prevention

At carrying out the robot, the antinoise mastics connected with drawing or anticorrosive structures, it is necessary to exclude hit of these materials in locks of the doors, directing a trench of glasses of doors, mechanisms Glass lifts, coils safety slaughter, and also on any mobile and rotating details of a running gear located from below of the Body of the car. After Body processing it is necessary to be convinced that all drain apertures of the Body are opened. Wrong drawing of materials can lead to decrease in service life of mobile details or increased to probability of corrosion damages of the Body. Besides, drawing of harm to personnel health is possible.

For protection of the Body from corrosion special anticorrosive materials which are put on internal and external surfaces металличес ких panels are used. Some steel details are protected with one – or two parties a metal galvanic covering or zinced. Wings are made of a steel sheet with a sheeting, doors, lateral panels, the panel located before a windscreen, a cover of a luggage carrier and лючки, floor panels, mudguards of wheel niches and the other details of the Body treated to action of excited environments and subject mechanical damages. In Body places where the moisture congestion is possible, apply special technologies of preliminary anticorrosive processing of metal surfaces. On the prepared internal surfaces of details of the Body put a protective layer from paraffin mastic. Open connecting seams of the Body are processed by hermetic, on mudguards of wheel niches, the bottom of the Body and internal surfaces of doors is put a layer водооттал nodding and shumo-absorbing mastic. Any repair work connected with damage or removal of an anticorrosive covering, can lead интенсив ache the subsequent corrosion of not protected sites of the Body. Therefore it is very important after end of repair or replacement of details of the Body qualitatively to put an anticorrosive protective layer from the materials recommended for application in the conditions of service station. At Body manufacturing all metal surfaces are exposed to preliminary anticorrosive processing and preparatory layers of a sheeting are put on them. After repair or replacement of details of the Body it is necessary to process anew all not protected metal surfaces of the Body. This processing should be spent before putting гермети зирующие structures, шумоизолирующую mastic or the basic layer of an anticorrosive covering.

In the course of Body manufacturing connect тельные seams of details are condensed with hermetic which not only interferes with penetration of water and a dust into the Body, but also is anticorrosive protection. Hermetic is put on interfaced surfaces of external and internal panels of doors, covers of a luggage carrier, a cowl, details of wheel niches, lateral panels of the Body, panels of a floor, a roof and other details of the Body. The condition герметизированных connections of Kuzovnyh of details can be easily estimated visually. At detection of damages of consolidations of connecting seams it is necessary to restore their hermetic sealing at once. Places of interface of new panels with Body details should be processed hermetic before installation on the car. New doors and the luggage carrier cover, established instead of old, also should be processed hermetic on all perimetre of an edge of a connecting seam.

Welded seams, фланцевые connections or connections of details of the Body внахлестку are condensed with plastic hermetic of an average consistence. Hermetic should keep elastic properties after drawing on the Body and give in to colouring. With the big backlashes it is necessary to apply hermetic of a semifirm consistence to processing of open seams. At structure drawing необходи мо to be guided by firm-manufacturer instructions on packing. After Body repair it can be demanded подкраска some details, for example, a cowl, wings, doors, lateral panels, a cover of a luggage carrier, a roof of walls of a motor compartment, the bottom panels of the Body or internal panels. Thus it is necessary to apply the usual technology including preparation of a surface under painting/drawing of a first coat and the basic layer of a paint and varnish covering. Antinoise mastics which are put by dispersion on various metal panels, provide except noise level decrease in car salon also anticorrosive protection, and consolidation of connections of details of the Body. If the antinoise covering is damaged as a result of failure or at carrying out of repair work, it should be restored by means of the materials recommended for application in the conditions of service stations. At installation on автомобильновой Kuzovnoj of a detail (instead of old) it is necessary to put on it a layer of antinoise mastic. The arrangement of places of drawing of a covering and a thickness of a layer should correspond to the detail which have passed factory processing.

For anticorrosive protection of details of the Body it is recommended to use structure of mark ЗМ Rust Fighter-1 or an equivalent substitute For protection against corrosion of large-sized details (doors, lateral panels, panels of a floor, a cover of a luggage carrier, a cowl, wings etc.) it is necessary to cover them with a first coat layer. Drawing of an anticorrosive covering is made in the following sequence.

PERFORMANCE ORDER

1. To clear a metal surface of a detail of the Body. 2. To put a preparatory layer. 3. To put a hermetic layer on all preliminary condensed connections. 4. To put a paint coat in necessary places of the Body on opened фланцевые connections, external seams and details of the bottom part of the Body. 5. To put a layer of antinoise mastic (similarly factory processing). 6. To put a layer of anticorrosive structure. 7. To put on the bottom of the Body a layer of protective structure.
