The chemical formula of sodium hydroxide is NaOH, commonly known as caustic soda, caustic soda and caustic soda. It is a highly corrosive caustic soda, generally in flakes or blocks, which is easily soluble in water (soluble in water) to form an alkaline solution. In addition, it also has deliquescence and is easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air.
Caustic soda is widely used in pig farm disinfection because of its low price, but what you may not know is that if you don't pay attention to the concentration, your caustic soda solution may not have disinfection effect!
Misunderstanding of caustic soda disinfection:
The amount of sodium hydroxide added to the vehicle disinfection pool is not enough; Vehicle tires are disinfected in an unwashed caustic soda tank; The personnel's water boots were not cleaned and stepped on the disinfection basin with pig manure.
Pig farms often do not calculate the amount of caustic soda required or weigh the caustic soda and add it at will. For example, put 5 shovels of caustic soda (about 5 kg per shovel) in the vehicle disinfection caustic soda tank, which is considered to be very high. If calculated carefully, it may not be enough.
Correct operation: carefully calculate the amount of caustic soda in the disinfection tank. For example, how much caustic soda needs to be added to reach the concentration of 2% in a 6m * 3M * 0.2m deep caustic soda tank?
Primary water volume: 6 × three × 0.2=3.6m3，3600kg × 2%=72kg, it is necessary to add caustic soda 72kg to meet the required concentration. The shovel is only 25 Jin, not enough!
If the disinfection tank is irregular, the water flow per minute can be multiplied by the water addition time to calculate the total water volume, and then calculate the required amount of sodium hydroxide.
It is easily affected by organic matter. The disinfection effect will be affected if the tires are stained with mud and the boots are stained with pig dung. It can enter the disinfection tank only after cleaning.
