PP cotton filter elements with different physical and chemical properties should be selected with different cleaning agents and disinfectants for cleaning. Choosing the appropriate cleaning agent and disinfectant can effectively prolong the service life of PP cotton cotton filter element.
1. Common PP cotton cotton filter element cleaning agent：The most general method, the use of high-pressure water spray washing dirt, preliminary cleaning PP cotton cotton filter element.
Particle grinding agent：The cleaner containing small abrasive material can dilute the dirt and is used for the PP cotton filter element that is difficult to clean.
Weak acid agent：Using weak acid washing, suitable for general PP cotton cottolonin routine cleaning.
Salt cleaning agent：Contains sodium chloride and other salts, used to remove calcium and other hard dirt.
organic solvent：Some organic solvents can effectively clean PP cotton cotton filter element, but they have some toxicity.
2. Selection of a disinfectant
Different disinfectants have different physicochemical effects on the polymer materials.
Chlorine preparation
Chlorine disinfectants are cheap but corrosive to polymer and have good disinfection effect.
hydrogen dioxide solution
Non-toxic and stable, with good compatibility for polymer materials.
Alcohol disinfectant
Cheap, efficient but volatile, with less effect on the polymer.
Polymeric ester amine disinfectant
The price is slightly higher but stable to the polymer materials, lasting disinfection effect.
In conclusion, the compatibility with polymer materials should be considered when selecting the cleaner and disinfectant of PP cotton filter element. Weak acid cleaners and hydrogen peroxide, alcohol disinfectants are more safe and convenient. Through reasonable selection, the service life of PP cotton cotton filter element can be extended.
