Solutions Belzona for the maintenance of tanks

Protection in front of the chemical attack

Given the products with which work, the chemical plants are installations that require of a complex equipment and big measures of hygiene. One of the indispensable elements in this industry are the tanks. These are key pieces in the storage and processed of the chemical products and his operation and conditions of hygiene are of main importance for the optimum performance of the plant and to fulfil with the rules of valid hygiene.

Because of the conditions in that they work, these tanks are exposed to different chemical agents that affect the integrity of the materials in which they are manufactured and what can cause escapes contaminantes.

To protect the interior of the tanks these revisten generally with ebonita, which offers very good properties of chemical resistance but at the end of his useful life, cuartea and cracks allowing so the chemical product penetrate and damage the helmet of the tank. In front of this situation, the solution more commonly used in the industry, is the application of a new revestimiento of ebonita. Given the properties of this, to llevar his application requires of work in hot and personal and skilled team, by what has to move the tank to a workshop conditioned; all this involves high costs to which it will be necessary to add the derivatives of the stop in the production.

At present in the market of the coatings industrial exist compound polymeric that offer a solution on a long-term basis for these problems, allowing solve them in situ and with a minimum time of stop. One of the products stood out, is Belzona 4311 (Magma CR1), a revestimiento of high performance that offers an exceptional protection in front of chemicals and that thanks to his composition, without dissolvent and fraguado in cold, can be applied in situ without need of work in hot.

Permanent protection

The optimum performance of the properties of this solution Belzona has been checked by several chemical plants in Spain. One of the most stood out cases is the one of an important factory of PVC situated in the province of Barcelona, which had a problem in the interior of one of his tanks that stored a dissolution of acido clorhídrico to 26%; the damage concentrated in the near internal surface to the filter where because of the profile of the zone, the revestimiento of ebonita suffered fractures by which penetrated the acid that was damaging the helmet of the tank. To solve this situation the company decided to contact with Rodator, distributor authorised Belzona for the north of Spain. Like this, the technicians of Rodator recommended the use of a solution based in Belzona 4311 (Magma CR1).

First prepared the area damaged, withdrawing part of the revestimiento in bad state and leaving the sustrato in optimum conditions for the application of the solution. It proceeded then to apply Belzona 4311 (Magma CR1) a product that recovers the profile of the stray metal and protects it in front of the chemical attack. Thanks to his properties this solution offers in addition to resistance to the chemical attack, an optimum adhesion to different substrata what allows to seal the zone warning the entrance of acid.

This solution Belzona, without dissolvent, provided a permanent protection in front of the chemical attack allowing do the application in situ, by a notably inferior cost to the that had supposed the revestimiento complete of the tank, deleting the risks of the work in hot and minimising the time of stop.
