Elastomers of liquid application, an alternative to the replacement of components of rubber

Marta Marco, Marketing Executive, Belzona 16/04/2013

Given the current economic situation, the costs of maintenance are an increasingly important worry in the industry. Like consequence, the possibility to repair equipment and machinery in place to replace them is turning into the option preferred between the professionals of engineering and maintenance.

Components of rubber like sellantes, together and attachments can damage by abrasive wear and result very difficult to repair. Because of the cost of the spare pieces and to his limited availability in some occasions, replace all the team is often the only option, what supposes a high cost. Even when the pieces of replacement are available, the times of delivery can be a problem.

Application of an elastomer Belzona in the mould.

Belzona Manufactures a wide range of products elastomers of liquid application for the repair and moldeo of components of rubber without need of work in hot. These elastomers can apply easily without need to use special tools, allowing an application in cold and fraguado to temperature acclimatise. Besides, they adhere to practically all type of substrata. Thanks to his liquid application, the elastomers of long length of Belzona allow to re-create complex forms, providing protection against the abrasion, the erosion and the wear.

The products elastomers of Belzona use in a big variety of situations, including the creation of flexible moulds and components of rubber, reconstruction of boards and sellantes, and repair of boards of horizontal expansion. The utilisation of conditioners of surface allows to attain an excellent adhesion to the sustrato. For moldeo of components, requires the use of an agent desmoldeante that it avoid the adhesion of the elastomer to the mould.

To way of example, the pumps of lobule employ in severe conditions like the processed of waste water in stations debuggers. The wear of the rotors of lobule causes losses of efficiency in the process, by what require to be replaced. The elastomers of the Series 2100 of Belzona can use to re-create and recover lobules damaged.

The reconstruction of cojinetes arbotantes is another typical application of the elastomers Belzona, since they can deteriorate and wear out with ease. In the inferior example, employed an elastomer of liquid application to re-create the cojinetes arbotantes lubricated by water in pumps elevadoras of water of mar. The high content in sand of the water had resulted in a fast wear of the cojinetes. It created a mould with Belzona in which it applied the agent desmoldeante Belzona 9411 (Release Agent). To continuation, Belzona 2131 (D&To Elastomer) poured in the mould to re-create the cojinete. Once that the material there was fraguado, the mould withdrew with ease.

To date, the success of the solution of Belzona has resulted in more than 300 cojinetes re-created for this customer. This solution allows to re-create cojinetes by a fraction of the cost of cojinetes new.

Other applications of the elastomers Belzona include the creation of boards to the measure and the repair of boards of expansion.

The elastomers of liquid application and fraguado in cold of Belzona allow to save big quantities in costs of maintenance and have showed an excellent resistance on a long-term basis to the abrasion, the wear and the erosion.
