Resumo(s)
Muitas instalações municipais são alvo de manutenção permanente, devido ao uso de
produtos químicos que provocam a corrosão e degradação dos mais diversos materiais.
Esta degradação acarreta custos elevados para os municípios e privação de uso de
algumas instalações devido a manutenção curativa ou preventiva.
Um estudo adequado do efeito dos produtos utilizados, poderia conduzir à utilização de
materiais mais nobres, que aumentasse significativamente o tempo de vida dos produtos
mais atacados pela degradação por corrosão, através de estudos que permitissem avaliar
a relação custo-benefício e, caso esta fosse favorável, proceder à substituição de
determinados componentes em materiais relativamente fracos, por outros com uma
maior capacidade para resistir aos ataques produzidos pelo meio em que estão inseridos.
Este estudo foi efectuado com vista a estudar a degradação de determinados materiais
expostos essencialmente à acção do Cloro em instalações municipais, permitindo assim
seleccionar novos materiais que permitissem uma vida útil dos componentes mais
alargada, estudando convenientemente a relação custo-benefício.
Foi possível observar que a introdução de alguns materiais mais nobres, poderá reduzir
drasticamente as operações de manutenção, diminuindo os custos e reduzindo também o
tempo de indisponibilidade dos equipamentos municipais.
Many municipal facilities are subject to ongoing maintenance, due to the use of chemicals that cause corrosion and degradation of the most diverse materials. This degradation entails high costs for municipalities and use loss of some facilities due to curative or preventive maintenance. A proper study of the effect of the products used, could lead to the use of noble materials, which can increase significantly the lifetime of products more attacked by degradation by corrosion, through studies that allow to evaluate the cost-benefit ratio and, in the case of this being favourable, proceed to the replacement of certain components made in relatively weak materials, by others with a greater capacity to resist to attacks produced by the environment into which they are installed. This study was carried out with a view to studying the degradation action of certain materials exposed primarily to the chlorine in municipal facilities, thus allowing select new materials that let a longer component life, studying conveniently the corresponding cost-benefit ratio. It was possible to observe that the introduction of some better selected materials, can dramatically reduce maintenance operations by lowering costs and reducing the time of municipal equipment unavailability.
