Cleaning Protocol For Porous Materials

The dirt attached to the porous metal surface or the particles embedded in the micropores are washed away by using organic solutions or non-polar solutions. After cleaning, be sure to rinse with clean water to remove detergent residue.

Choosing the Right Detergent:

  • For inorganic compounds:
    Use diluted acids that won't corrode the base metal. Examples are Nitric, Phosphoric, Citric, and Oxalic acids. These can be combined with detergent additives if needed.
    Commercially available scale removers include Oakite 31 and 33 (acidic), Oakite Low Heat Cleaner 3 (alkaline), Calgon EZE 294S (alkaline), and Alkonox Citranox (acidic).
  • For organic foulants:
    Caustic cleaners are ideal. Solvents, soaps, and detergents can also be utilized.
    Common household detergents can be effective.
    If there's a mix of contaminants, start with caustics to get rid of oils. Then, employ acidic cleaners or acids to remove scales and mineral deposits.

  • For biological contaminants:
    Opt for potent oxidizing agents such as Clorox (sodium hypochlorite) or peroxide.
    Both acidic and caustic cleaners can be beneficial.
    Alconox TERG-A-ZYME is specifically effective against proteins and food residues.

Final Note: Always ensure the chosen cleaning agent is compatible with the material to avoid damaging the porous structure. After the cleaning process has been completed, the parts must be tested to determine if they are in fact clean.

Porous metal cups are vessels fabricated using metal materials that have micro-porous structures. These microscopic pores allow for specific properties such as controlled permeability, increased surface area, and enhanced adsorption capabilities. They can be used in various applications including filtration systems, diffusion processes, and certain advanced manufacturing techniques.

Porous metal cups can be made through various methods including sintering, metal injection molding, or additive manufacturing. Sintering, one of the most common methods, involves compacting metal powders at a temperature below the melting point which allows for bonding at contact points creating a porous structure. The size and distribution of pores can be controlled through the selection of metal powder size and the sintering process parameters.

Porous metal cups have a variety of applications across several industries. They can be used as filtering elements in liquid or gas filtration systems, where they can separate contaminants or particles from a medium. They are also used in fluidization processes, as catalytic supports, and in biomedical applications for instance as scaffolds in tissue engineering. Additionally, they can function as flame arrestors or in muffling components in noise reduction systems.

The choice of metal for making porous metal cups generally depends on the specific application and its requirements. Common materials include stainless steel, which offers resistance to corrosion, high strength, and temperature resistance. Other metals such as titanium, nickel, or aluminum can also be used, offering a range of characteristics including lightweight properties or enhanced biological compatibility in the case of titanium.

The maintenance and cleaning of porous metal cups depend on their usage and the type of contaminants they are exposed to. Typically, they can be cleaned by backflushing, ultrasonic cleaning, or by using appropriate cleaning agents to remove accumulated particles or substances. It's important to follow the manufacturer's guidelines to ensure proper maintenance and to avoid damaging the porous structure, which could potentially impair the performance of the cups. Regular inspections are also recommended to assess the condition of the cups and determine when replacements are necessary.
