use of permanganate in stopping leaching process


2018 3 29  use of leaded solders. However, the use of lead pipework and leaded solders has been prohibited for many years and so this is no longer an issue, except perhaps in very old buildings with original pipework. The following sections deal with the many different types of copper corrosion in plumbing systems.

2019 5 14  Discoloration of copper and its alloys also may occur at the curing temperatures normally recommended for thermoset coatings. It is wise to use low curing temperatures and short curing schedules to avoid such in process discoloration. Catalytic activity by copper sometimes allows lower temperatures or shorter curing schedules to be used.
