Rubber Mixtures In Metal Gumming Processes

Gumming is one of the ways of corrosion protection of materials. Gumming - application of rubber coating on surfaces exposed to aggressive media (acids, alkalis, gases) during operation.

Rubber mixtures used for gumming are applied to the metal surface with which it is joined during the vulcanization process. In this case, only high-quality rubber compounds are used.

Gumming is the most effective method of anticorrosive protection of metal surfaces from the influence of aggressive media such as organic acids, alkalis, salt solutions. This method has several advantages over other methods of corrosion protection, namely, coating:

- has high water and chemical resistance;

- resistance to abrasion;

- resistance to fluctuations in dynamic loads;

- resistance to significant fluctuations in temperature;

- Has low gas permeability.

With the help of gumming, they improve the wear resistance and temperature resistance of metals. This method protects the metal surface of various products, including shafts used in a wide variety of industries. Such protection can significantly increase the life of the shafts. It should be noted that after processing the product also acquires dielectric properties. The objects of gumming are often various tanks and cisterns intended for storage and transportation of acids, alkalis and other corrosive substances.

When performing work on rubberizing of metal surfaces, the worn is restored and a new coating is applied, for which raw rubber , silicone, polyurethane is used.

The gumming is carried out by a hot or cold fixing method.

When rubberized using the hot fixing method (without the use of a mold or using it), the raw rubber is bonded to the surface metal during the vulcanization process. In this case, high-quality silicone and rubber compounds are used.

When rubberizing with the method of cold fastening vulcanized rubber is fixed on the metal surface with the help of glue. In this case, special adhesives are used, working not only mechanically, but also chemically.

It is necessary to pay special attention to the method of gumming shafts - extrusion. This method makes it possible to obtain the highest coating quality and provides a significant increase in the service life of the shafts. When carrying out work using this method, only rubber compounds of high quality are used.

Processes of gumming equipment that has significant geometric dimensions, produce at the place of its installation.
