Metal / Scurf - Organic Residues

Organic corrosion on stainless steel can lead to corrosion, since, for example, blood contains chlorides, among other things. At elevated concentrations, they cause pitting corrosion and / or corrosion cracking due to internal stresses.

Metal / Scurf - Organic Residues

  1. Metal / scurf - remnants of process chemicals
    Depending on the size of the residue, the type of instrument and the nature of the surface, light to dark gray raids / blooms may appear as spots or dots. Their visual distinction can still increase after sterilization. Types of surface changes {foto28} Hollow handle with visible residues {foto29} Loading trolley suitable for washing and rinsing ophthalmic instruments {foto30}
  2. Metal / scurf - lime water stains
    Types of surface changes {foto31} Limescale wash chamber Corollary: tools with traces of lime Pour / paint from milky to gray. Depending on the situation, large or irregular spots with an edge on the surface of the instrument or washing / disinfecting installations. Lime content in water too high during cleaning or last rinsing.
  3. Metal / plaque - silicates and other mineral compounds
    Types of surface changes {foto32} Typical silicate dyeing of the washing chamber and instrument surface due to the use of a cleaning agent containing silicates, or high content of silicic acid in water {foto33} Typical silicate surface dyeing of instruments with steam sterilization completely desalted
  4. Metal / scurf blackening due to oxidation
    Types of surface changes {foto34} Sample - tires made of titanium: Left tire - new, from the factory. Right tire - after machine washing. Usually the color changes evenly. However, it can also be in the form of spots / various colors. {foto35} Clamp part: retainer and ring area {foto36} Wound hook with black painted hardened Cr-steel rod and the remaining clean handle and sheet
  5. Metal / scurf - staining / discoloration of color plasma layers
    Types of surface changes {foto37} Example: black, TiAIN coated stamp. Motley brilliant color change or complete absence of coating with unchanged gold-plated components (end screw, springs) {foto38} Stamp: new Origin and causes Surface reaction under the action of cleaning solutions with addition of hydrogen peroxide and / or washing solution, for example, with high
  6. Metal / Corrosion - Rust and Rust / Secondary Rust
    Types of surface changes {foto58} Left - filter holder with partial corrosion Reason: severe rust damage of the sterilization chamber causes secondary corrosion / raids ¦ Separate randomly scattered rust particles. ¦ Brown, usually locally limited sediment / rust buildup. ¦ In direct extensive contact with highly corroded tools as secondary
  7. Non-infectious diseases of the umbilical cord and umbilical cord
    The umbilical cord represents the transition of the skin of the anterior abdominal wall to the umbilical cord sheath. The size of the skin growth usually measures no more than 1-1.5 cm. It does not affect the condition of the newborn. It may be regarded as a cosmetic defect, decreasing with age. The treatment does not require. The amniotic navel is a transition of amniotic membranes from the umbilical cord to the anterior abdominal wall in
  8. MEATING OF MEAT AND FORMATION OF DRY SPIN
    Slime may form on the surface of the meat. The cause of meat mucus is the intensive development of mucus-forming microorganisms. Such microorganisms include various types of lactic acid bacteria, yeast and micrococci. On the dry surface of meat, the microbes that form mucus do not grow, the main conditions for their development are the presence of humidified areas, and a relatively high temperature.
  9. Diseases of the skin, subcutaneous tissue, umbilical cord and umbilical wound
    Diseases of the skin, subcutaneous tissue, umbilical cord and umbilical cord
  10. Organic nitrates
    Nitrates have been used in clinical practice for more than 100 years. Nitroglycerin has been prescribed to relieve angina attacks since 1879. The main representatives of the group of organic nitrates are glycerol trinitrate (nitroglycerin), isosorbide dinitrate and isosorbide mononitrate. The latter is a natural active metabolite of isosorbide dinitrate. All drugs in the group
