Wedge wire screens are susceptible to rusting due to the breakdown of their passivation layer when exposed to substances in the air. To extend the lifespan of wedge wire screens, proper storage is crucial!
When wedge wire screens have scratches or nicks, avoid contact with acidic or alkaline substances and strictly prohibit the use of detergents. Scratches or nicks weaken the corrosion resistance of the passivation layer on the wedge wire screen surface, leading to pitting corrosion due to self-excitation reactions, forming small holes. Contact with unclean substances accelerates the corrosion process, which is very detrimental to the wedge wire screen.
Wedge wire screens should not have various acids or bleaches attached to their surface, and the accumulation of dust and dirt is strictly prohibited. If these substances are present, use a neutral detergent or warm water for cleaning.
For long-term storage, wedge wire screens should be kept in a well-ventilated room. Regular inspection and cleaning and maintenance of the wedge wire screens are also necessary to ensure proper storage and extend their lifespan.
Wedge wire screens should never be stored in a sealed room with high temperature or humidity. They must be stored in a well-ventilated room with a temperature controlled at around 20 degrees Celsius and a humidity level not exceeding 50%. They should also not be stored together with highly acidic or alkaline substances.
