An introduction to the corrosiveness of hydrogen peroxide sterilization to the environment
The properties of the disinfectant itself. Hydrogen peroxide sterilization equipment is divided into two types: vaporization and atomization. The equipment itself is only a generating device. The disinfection effect mainly depends on the disinfectant itself. Hydrogen peroxide itself has oxidative properties. The atomization uses 2.2% hydrogen peroxide + 0.45% peracetic acid or 8% pure hydrogen peroxide disinfectant. The concentration is particularly low and the compatibility is particularly good, because the hydrogen peroxide used in the hospital is 3% hydrogen peroxide, which can be directly applied to the wound. It is coated on top, so the compatibility of 2.2% is better, even if it is condensed dozens of times, there will be no visible corrosion to the naked eye. Vaporization adopts 35% hydrogen peroxide. Once the temperature and humidity are not well controlled, the color steel plate will foam after condensation once, so the temperature and humidity before sterilization must be well controlled. The initial temperature is 18~26℃, and the humidity is 40~60%. Can.
It is also related to the material of the color steel plate. For example, the color steel plate before 2000 may have problems such as damage, aging, and many impurities in the material, which are easy to corrode, but the color steel plate after 2010 is generally very compatible. For the sake of rigor, before sterilization, we can use the leftovers of the color steel plate to do the disinfection liquid titration test, and use the disinfectant with different concentration gradients to test the compatibility of the color steel plate multiple times to judge whether the color steel plate is suitable for hydrogen peroxide. If the material is not resistant to hydrogen peroxide, it can also prevent corrosion by sticking PVC film.
